RESUMEN
Án intensive plant survey by the senior author of the St. Marks National Wildlife Refuge included discovery
of an unusual Xyris that in normal years would probably have been accessible only by boat, but the drought
for the spring months of 2007 was the most severe on record for the Florida panhandle (USA). This enabled
collecting the plants on foot—albeit I was up to my armpits in water on one occasion because at some sites
the new Xyris grows on floating islands. The species description follows the format and terminology of Kral

Common name. —*“St. Marks yellow-eyed grass” would be an appropriate common name
Phenology.—Transplants of all relevant collections were potted in orginal substrate and cultivated in
a flooded wheelbarrow in Anderson's backyard for observation. The new species blooms from late June to
early October. Flower buds unfurl and petals are fully expanded around 11:30 am (EDT); in a close associ-
ate, X. fimbriata Elliott, the flowers open around 1:00 pm and stay open about two hours, whereas those of
X. panacea remain open until around 4:00 pm. Flowers of X. smallinana Nash (in this region) open around
5:00 pm, and their flowering does not overlap with the other species. Flowering observations among the
transplants were confirmed in the field.
Habitat.—The Refuge Comprehensive Conservation Plan (U.S. Fish and Wildlife Service 2006) lists
ponds in the Panacea unit variously as “coastal depression ponds” or “basin lakes” or “flatwoods lakes.”
The St. Marks yellow-eyed grass grows either in mucky, loosely matted sandy loam in shallow depression
ponds in longleaf pinewoods (with stems bases submerged in 10 or more centimeters of water or in poorly
congealed loam of floating islands in those depression ponds (with stem bases only slightly submerged).
Some ponds are ringed with a thicket of Cyrilla racemiflora L., whereas others are bounded by Hypericum
fasciculatum Lam. The new species was vouchered from five ponds in the area; it is presumably present in
several other ponds that Anderson planned to visit, but his 2007 field season was terminated abruptly with
a broken leg.

DISCUSSION
The common associate Xyris in these ponds is X. fimbriata, a species of similar habit and pigmentation but
with two scabrid scape costae (rather than a single, smooth one), with spikes mostly shorter and of broader
outline, with lateral sepals strongly exserted, their keels densely fimbriate (Fig. 2). Also, a few diminutive
flowering plants of X. jupicai L. Rich. were seen at the type locality. Ponds 3.8 km and 4.3 km NE of the
new taxon’s range had the “X. panacea zone” replaced with X. smalliana exclusively, see Anderson 23456,
23457 (FSU, VDB). In the general area, though not an associate, is X. stricta Chapm., another tall species
with similarly ascending, long-sheathed, slender-bladed leaves and similar pigmentation. This taxon also
hasnarrowly ellipsoidal to subcylindric spikes with similar design of bracts. However, this taxon has scapes
distally broader, flatter, actually 2-edged, its lateral sepals are broader, with broader, firmer, ciliolate keels
whose tips are not exserted; its seeds are typically farinose.
The St. Marks yellow-eyed grass is distinctive with a suite of vegetative and floral features. The dark
red stem bases are somewhat bulbous and firm (being pale green and soft in X. fimbriata or pale green and

mucilagionous in X. smalliana); larger plants have stout vertical, rhizome
The flowering scapes are smooth with weakly developed ribs below the spikes. The spikes are cylindric,
longer than those of any other taxa in North America (Kral 2000). Flowers open earlier in the day and are
larger than those of other species (equally large petals are found in X. caroliniana Walter, but that species
differs in habitat and very many E e pd M More attention ae to be given to style position
amongst North American species; the | X. panacea may be exclusively
unique. The known range of the new species is ida Sech to warrant designating it a threatened or
endangered species.

Consideration of the role of hybridization in evolution has received new impetus SIM the availability of
molecular genetic data (Arnold 2006). It has long been clear that intersy y is a widespread

phenomenon in plants, with numerous clearly documented examples (e.g., Grant 1980), but there are still
questions regarding its evolutionary significance. Of perhaps greatest interest is hybridization between
species of lineages that have diverged morphologically to the point of being recognized as distinct genera.
This represents a potentially dramatic reversal of the process of evolution, which is normally considered
to be divergent, and it also presents a challenge to systematic classification based on phylogeny. It is thus
of considerable interest to examine closely possible cases of intergeneric hybridization to be able to assess
how frequently this phenomenon occurs.
A persistent myth is that intergeneric hybridization is common and perhaps even pervasive within
Asteraceae. For example, Robinson (1983) and King and Robinson (1987) invoke intergeneric hybridiza-
tion as an explanation for discordant distribution of morphological characters in Liabeae and Eupatorieae,
respectively. A search of the literature, however, reveals few well documented cases of natural intergeneric
hybridization in Asteraceae. Naturally occurring intergeneric hybrids have recently been documented by
McKenzie et al. (2004) and Saito et al. (2006). In some cases, artificial intergeneric hybrids have been made
successfully (e.g., Powell 1985; Carr 2003), and studies have found incongruence between nuclear and
chloroplast markers suggestive of past wide hybridization (Schilling & Panero 1996; Fehrer et al. 2007).
But documentation of intergeneric hybrids in most groups remains elusive. This prompted us to undertake
a detailed study of a putative case of intergeneric hybridization within the Astereae.
The name of the horticultural plant known as Solidaster cv. Lemore (Fig. 1) reflects its presumed
hybrid origin as a cross between species of Solidago L. and Aster L. The plant is unknown in the wild, but
appeared in European gard Iter the import of plants from North America (Nesom 1993). Its status as an
intergeneric hybrid depends in part, however, on the classification of one of its putative parents, the Upland
White Aster, which has been variously placed in Aster, Solidago, and Oligoneuron Small. The Upland White
Aster, S. ptarmicoides (Torrey & A. Gray) B. Boivin, has long been a source of puzzlement for taxonomists.
Its superficial outward appearance, especially its open corymbose and relatively large heads
with white rays and disk flowers, seems clearly that of an aster, as traditionally conceived, and is reflected
in its common name. Despite this, considerable evidence has PEEL a bal affinity to the goldenrods,
including the observation of abundant natural hybrids with species go (Boivin 1972), considerations
of phytogeography and technical features of morphology (Brouillet & apie 1981), and a chloroplast DNA
restriction site study placing it within Solidago L. tl al et al e Nev ertheless, it is still widely referred
to as an Aster s.l. Another, somewhat different int tion of the genus Oligoneuron as
distinct from Solidago (e.g., Nesom 1993), which would include the Upland | White Aster as well as five other
species. Although the second parent of Solidaster has generally | considered to be a Solidago, particularly
S. canadensis (Brouillet & Semple 1981), Nesom (1993) suggested that based on morphology it was more
likely to be Euthamia graminifolia (L.) Nutt.
The taxonomic history of the Upland White Aster, Solidago ptarmicoides, has been reviewed by Brouillet
and Semple (1981), and only a brief summary will be presented here. Not only the generic placement but
also its species epithet has varied. The plant was originally described by Nuttallin Inula L., where it received
the appropriate epithet alba for its white rays and disk HOMES Menem GE to either Aster or Solidago
this epithet proved to be already occupied, and the alt its | to Achillea
ptarmica L., a widely cultivated garden plant; Fernald 1950) v was BE ig Nees. When placed in still
another genus, such as Oligoneuron (e.g., Nesom 1993), it reverts to the epithet album. Over its taxonomic
history, the species has been placed in nine separate genera by various authors (Semple & Cook 2006).
The taxonomic treatment of Solidago has been notoriously difficult (Semple & Cook 2006). Although
there are a large number of e similar SE in eastern North America, no clearcut morphological
apomorphy has been discovered that genus. Similarly, delimitation of infrageneric
groups has been elusive as has aa and ion of individual species, many of which differ
from one another by minute details of inflorescence form or pubescence. The situation is further compli-
cated by the frequent occurrence of both interspecific hybridization and polyploidy. Some representatives

of the genus are quite common and widespread and are particularly significant as dominants during early
successional stages of old fields, where several are components of a well studied ecological model system
(e.g., Abrahamson et al. 2005). Additionally, Solidago taxa have become invasive in Europe (Weber 2001)
and Asia (Dong et al. 2006), and are being used as models to understand the general evolution and ecology
of invasive species (Van Kleunen & Schmidt 2003; Jakobs et al. 2004; Meyer et al. 2005). The abundance
and ecological importance of Solidago therefore make a sound taxonomy highly desirable.
A number of studies have applied molecular data to the resolution of systematic problems in Astereae
(Suh & Simpson 1990; Morgan & Simpson 1992; Lane et al. 1996; Zhang 1996; Noyes & Rieseberg 1999;
Roberts & Urbatsch 2003; Urbatsch et al. 2003; Beck et al. 2004), so a considerable body of molecular data
has begun to accumulate for the tribe. Other than a chloroplast DNA restriction site analysis (Zhang 1996;
Semple et al. 1999), there has been no focus as yet for DNA sequence analysis on Solidago, although a few
sequences are available from other work. As part of an initial survey for suitable molecular markers, we
analyzed ITS and ETS sequence variation for several samples of Solidago that represented the major subunits
of the genus, as delimited by Semple and Cook (2006). Although the lack of suitable variation in these
markers led us to abandon any attempt to make a complete survey of the genus, one of the species that we
sampled was S. ptarmicoides, and sufficient data have been acquired to allow for an assessment of its generic
placement, as well as to clarify the parentage of its hybrid offspring, Solidaster cv. Lemore, which we report
here.
MATERIALS AND METHODS
Plant Material
A sample of Solidaster cv. Lemore (Fig. 1) was grown from material obtained commercially (Bluestone
Perennials, Ohio, USA). Samples of Solidago (Appendix) were either collected in the field or obtained from
herbarium specimens. Sampling was designed to include at least one member of each of the currently rec-
ognized sections and subsections of the genus (Semple & Cook 2006). To evaluate intraspecific variability,
multiple accessions of four species (S. canadensis, S. riddellii, S. ptarmicoides, and S. nitida) as well as an
additional sample of Brintonia discoidea were analyzed. Note that we have elected to follow the most recent
treatment of Solidago (Semple & Cook 2006), which deviates from nomenclature used in our earlier paper
10 | tl | ical | f Texas 2(1)
(Beck et al. 2004) by including Oligoneuron within Solidago but recognizing Brintonia parate from it; the
classification of related genera also follows the Flora of North America treatments.
Molecular Methods
Preparations of total DNA made from fresh (0.5-2.0 g) leaves generally followed the procedure of Doyle and
Doyle (1987), and those from herbarium material (ca. 0.1 g) were performed with the Dneasy Plant Minikit
(Qiagen, Valencia CA). The crude DNA extracts of some samples required further purification using the
Wizard Kit protocol (Promega, Madison, Wisconsin). Methods for DNA amplification and sequencing were
as described in Schmidt and Schilling (2000). Amplification and sequencing reactions for the IT'S region
were both performed using primers “ITS-4” and “ITS-5” (White et al. 1990). Amplification and sequencing
reactions for the ETS region were performed using primers Ast-1 (Markos & Baldwin 2001) and 18-S-ETS
(Baldwin & Markos 1998). All PCR products were checked by agarose gel electrophoresis. Sequencing was
done at the University of Tennessee Automated Sequencing Facility, utilizing the ABI Prism Dye Terminator
Cycle Sequencing reaction kit on an ABI 373 or ABI 3100 DNA sequencer (Perkin-Elmer Inc. Foster City,
CA). The initial sequence data text files were edited following comparison with the same data displayed in
four-color electropherograms before further analysis. Sequence alignment was performed using the Clustal
X (version 1.6) program (Thompson et al. 1994
RIDE of the ITS region for the sample of Solidaster cv. Lemore was undertaken to confirm ITS poly-
| from direct sequencing. The purified PCR products were ligated into pGEM-T (Promega,
Madison: Wisconsin) according to the manufacturers instructions. Competent Topl0 Fº (Invitrogen, San
Diego, California) cells were transformed via electroporation and the resulting colonies were screened for
plasmas d inserts by PCR using the original amplification primers. Plasmids were isolated from single
g an alkaline lysis/PEG precipitation protocol (Sambrook et al. 1989). Sequences
were obtained for ten independent clones.
Data for additional ITS and ETS sequences for Solidago were obtained from GenBank, as well as for
all of the samples placed in the same clade as Solidago s.s. in Beck et al. (2004; “Clade III”). Two data sets
were analyzed, the first of which utilized ITS sequences from a broad sampling of Solidago, with samples
of Brintonia discoidea as outgroups. The second utilized both ITS and ETS data with a broader sampling
of related genera (Appendix) to assess the placement of Solidago ptarmicoides and of Oligoneuron relative to
other Solidago, and samples of Sericocarpus tortifolius and Cuniculotinus gramineus were added as outgroups
for this analysis. ENEE E were analyzed using both maximum parsimony and Bayesian
approaches. Parsimony analys ted using PAUP* 4.0b10 (Swofford 2003), with gaps treated as
missing data, using a heuristic ac with 1,000 random addition replicates and with TBR branch swapping.
Bootstrap analysis (Felsenstein 1985) was performed with 10,000 replicates using the FASTSTEP search
option. Bayesian analysis was implemented in MRBAYES 3.0B4 (Huelsenbeck & Ronquist 2001) run for
ten million generations with four separate chains and trees saved every 100 generations. The number of
trees to discard as “burn-in” was assessed by plotting likelihoods of trees sampled throughout the run and
discarding all trees prior to the stable likelihood plateau (in both analyses the first 10% were discarded). An
appropriate maximum likelihood model of sequence evolution (GTR+I+G; General Time Reversible model
with a proportion of invariant sites and gamma distributed rates) for the Bayesian analysis was chosen for
both analyses using Modeltest (Posada & Crandall 1998).
RESULTS
Newly obtained ITS sequences for Solidaster cv. Lemore and for Solidago were consistent in length with
previous reports for the genus. In particular, there was extraordinarily little variation in length among any
of the sampled members of the genus; eae Sequence lengths varied from 627-629 bp. Insertion of
single 1 bp indels ired for five samples (tl 1 two deletions) to produce a completely
aligned matrix of length 631 bp for Ee entire ITS region. Similarly, there was little sequence length varia-
tion in allied genera, with individual sequences varying from 627-630 bp, and the aligned matrix was of
Schilling et al., Molecul lysis of Solidast Lemore 11
bi a 634. Tasse was also ony limited Palo variation between species of Solidago for the ITS region;
airwise comparisons revealed sequence divergence f generally less than 1%, with total differences between
samples of 1- 10 bp. Samples of Bier senem: were generally, although not always, more divergent, with
pairwise divergence values of 1-3% and total differences of 7-19 bp. The sample of Sericocarpus tortifolius
differed from all Solidago samples for at least 15 bp, but was still relatively similar, with overall divergence
values of 2—396; the sample of Cuniculotinus gramineus was somewhat more divergent, differing by 23—29
bp (496 overall divergence) from samples of Solidago. In the five species (S. canadensis, S. riddellii, S. nitida,
S. ptarmicoides, and Brintonia discoidea) where multiple accessions were examined there was at most one bp
difference among samples and no evidence of nonmonophyly.
The ITS sequence for Solidaster cv. Lemore was very similar to other Solidago sequences, but displayed
bp polymorphisms (Fig. 2) at the following positions: 18 (A/G), 106 (C/A); 514 (C/T), 611 (G/T), 612 (C/T),
613 (A/G). Visual inspection revealed that this pattern of bp polymorphisms would fit exactly with a com-
bination of the ITS sequences characteristic of S. ptarmicoides and S. canadensis (Fig 2.) Cloned ITS repeats
from Solidaster cv. Lemore exhibited ITS sequences that matched closely either those of S. ptarmicoides or
those of S. canadensis. Phylogenetic analysis in comparison to a broad sampling of Solidago showed that
consensus sequences from the clones clustered with some ESTE DEEN ie those Eon S. pone

of uland graminifolia, proposed by Nesom (1993) as the second potential parent of Solidaster, has been
shown to be relatively divergent from those of Solidago (Noyes and Rieseberg 1999), and its reported ITS
sequence (GenBank AF046982) differs from that of S. ptarmicoides by 4 indels as well as a minimum of 32
bp. Because the ITS sequence of Solidaster cv. Lemore did not show any evidence of indel polymorphisms,
and only a few bp polymorphisms, Euthamia graminifolia is clearly not one of its parents.
Approximately 450 bp of the ETS region were amplified for each sample of Solidago with the primer
pair 18S-ETS and Ast-1. Removing regions of poor sequence and uncertain alignment produced a matrix
with a total length of 444 bp, including 18 bp of 18S coding sequence. As with ITS, length variation among
sequences was minimal among Solidago samples: only a single 1 bp deletion in S. patula, and only a single
1 bp insertion in Stenotus and a 3 bp deletion in both outgroup taxa, Cuniculotinus and Sericocarpus, were
required for complete alignment of this portion of the ETS region. Levels of sequence divergence for ETS
were similar to those for ITS, with pairwise divergence values among Solidago samples of 0-1% (0-4 bp)
and among all samples reaching a maximum of 4% (17 bp). The ETS sequence of Solidaster cv. Lemore was
basically identical to that of S. ptarmicoides, although each sequence ex hibited a single, non-informative bp
polymorphism (position 124 in Solidaster, 36 in S. tadas both A/G). Other than the polymorphic
positions, the ETS sequence of S. canadensis differed from those of S. ptarmicoides at only a single position,
and there was no evidence of polymorphism in the sequence of Solidaster cv. Lemore at this position.
For phylogenetic analysis to assess the placement of S. ptarmicoides relative to Solidago, the ITS and
ETS sequence data were analyzed together, producing a combined matrix of 1078 bp in which there were
46 potentially parsimony-informative characters and 85 additional variable but parsimony-uninformative
characters. The results of phylogenetic analyses (Fig. 4) reflected the overall low levels of divergence in
providing a poorly Ee tree with ne dni > ver of EEN for many branches. The results of the
parsimony and Bayesian h the Bayesian tree was more resolved.
A monophyletic group m to clade HI af Beck et al. (2004) was defined relative to Cuniculotinus
gramineus and Sericocarpus tortifolius with a posterior probability of 1.00 (Bayesian) and 100% (bootstrap),
respectively. At the next level of branching there was a large polytomy in the strict consensus tree, within
which there was a strongly supported clade formed by the three species of Chrysothamnus, C. scopulorum,
C. stylosus, and C. viscidiflorus (1.00; 99%), a variably supported clade with Petradoria and Stenotus (0.97;
57%), and a strongly supported clade formed by Solidago, Chrysoma, and Brintonia (1.00; 76%). Within the
last clade, there was a Chrysoma + Brintonia clade (0.79; <50%) that was sister to a Solidago s.s. clade (1.00;
69%). Within the Solidago s.s. clade, there was littl lution in the tree, with the only bootstrap

with those presented by Urbatsch et al. (2003) in placing Oligoneuron within Solidago as well as showing
Chrysoma as a near outgroup to Solidago relative to Sericocarpus. They also support the revised classification
of Chrysothamnus and related genera presented by Urbatsch et al. (2005).

DISCUSSION
Molecular data showed that Solidaster cv. Lemore is not an intergeneric hybrid by providing evidence not
only to identify its parents (Figs. 2, 3) but to show clearly that both are accurately placed as members of
Solidago (Figs. 3, 4). The combination of Solidago ptarmicoides and S. canadensis as its progenitors fits well
with what is known of the origin of Solidaster, and has been proposed previously (e.g., Brouillet & Semple
1981). It has been clear based on morphology that S. ptarmicoides was one of the parents, and S. canadensis
was one of the few goldenrod species naturalized near the nursery where Solidaster was first discovered
(Nesom 1993). Although Solidaster does not show complete additivity in morphological features relative to
S. ptarmicoides and S. canadensis (Nesom 1993), there are now numerous well documented cases of hybrids
failing to exhibit one or more seemingly characteristic traits of their progenitors (Rieseberg 1995). Note
that these results apply specifically to the cultivar Lemore, and other material marketed as “Solidaster” (or
in florists shops as “Aster”), which may exhibit somewhat different morphologies, may not have a common
origin. Laureto and Barkmann (2005, pers. comm.) present molecular-based evidence for the hybrid origin
of another species, S. houghtonii Torr. & A. Gray ex A. Gray, that involves members of sect. Ptarmicoidei (S.
riddellii) and sect. Triplinerve (S. gigantea), and similarly does not show additivity in morphology. Ge
of Euthamia graminifolia as a potential parent of Solidaster also refut ther potential interg
ization hypothesis (Nesom 1993).

The major conclusion from phylogenetic analysis of ITS = ETS sequence data is that there is strong
support for the inclusion of S. ptarmicoides within Solidago. PI learly placed it in the clade
EE to Solidago s.s s Fig, 4), ine it Seneca in lle sequence (ITS and ETS combined) from other
lit ff (vs. S. shortii). There wa sequence
data to segregate Oligoneuron, presea in the data set by five of its six species dude S. ET
as a distinct genus; the combined ITS and ETS data in fact placed one of the Oligoneuron species, S. riddellii,
with S. caesia from sect. Solidago, albeit with only weak support (Fig. 3, 4; see asterisks). The sequence data
did, however, provide weak support for restricting the limits of Solidago to exclude Brintonia and Chrysoma,
although the group formed by inclusion of these genera with Solidago would be monophyletic. These results
Cd mirror those presented by ara Kee reproduced in Semple et al. 1999) dran on pepe
NA restriction site data, and ] tional support for the most recent and
treatment of the abovementioned taxa (Semple & Cook 2006).
A notable aspect of the ITS and ETS sequence data was the striking lack of divergence among mem-
bers of Solidago. By contrast, ITS divergence in Eupatorium L. another genus of Asteraceae with a similar
geographic range and occurrence in old field habitats, is 2-6% between species (12-43 bp differences;
Schmidt & Schilling 2000; Schilling et al. 2007); Eupatorium is further differentiated from Eutrochium Raf.,
which are widely treated as congeners, by two indels (loss of a 13 bp region in Eupatorium and addition of
a 3 bp region in Eutrochium) in addition to a minimum of 896 (33—61 bp) divergence. It should be noted
that a previous chloroplast RFLP analysis (Zhang 1996) reports a higher level of variation within Solidago,
and the resulting phylogeny strongly supports certain previously hypothesized groups. These contrasting
levels of phylogenetic signal are best explained by the relative amount of DNA sequence scored in each
study. Extrapolating from the values reported in Lane et al. (1996), approximately 2.5—3 kb of chloroplast
sequence was assessed for variation in the Zhang study, compared to the approximately 1.1 kb ITS/ETS
dataset analyzed here. In addition, previous work in Asteraceae indicates that chloroplast RFLP datasets
can be more informative relative to those from ITS sequence (Morgan 1997). The most obvious possible
source of the lack of ITS divergence in Solidago is that species level divergence is very recent. Other possible
contributing factors include relatively large effective population sizes and the potential for homogenization
through widespread interspecific hybridization followed by concerted evolution. Hybridization is tradition-
ally viewed as widespread within Solidago (Cronquist 1980), and homogenization via concerted evolution
is potentially a rapid process DIE o (Franzke & Mummenhoff 1999). The relative lack of
differentiation in ITS seq y distantly related congeners, which because of geographical
considerations are unlikely to be part di a Geen hybridization network, suggests that the primary cause is
recency of divergence. This suggests that the striking ecological differences between Solidago species may
have arisen during relatively short periods of time and indicates that resolving the phylogeny of Solidago
will be a major challenge that will require markers evolving more rapidly than ITS and ETS.

Key Wonps: Kohleria, Capanea, Monopyle, Ecuador, Gesneriaceae
The most recent treatment of the genus Kohleria Regel is that by Kvist and Skog (1992), who recognized 17
species. More recently, Roalson et al. (20052) transferred the two species of the genus Capanea Decaisne ex
Planchon to Kohleria making it currently a genus of 19 recognized species. The revised circumscription of
Kohleria to include Capanea (Roalson et al. 2005a) is based primarily on molecular data from the nuclear
ribosomal DNA internal transcribed spacer region, the chloroplast DNA trnL intron and trnL-trnF intergenic
spacer region (Roalson et al. 2005b). Traditional Kohleria (e.g., the recent monograph by Kvist and Skog,
1992) would be paraphyletic with the exclusion of Capanea. Thus, many of the features that differentiated
Capanea are autapomorphic for a well-supported clade nesting in Kohleria (Roalson et al. 2005b).
The new species described here has a history of being collected in the Carchi province where it is locally
abundant in cloud forests. It was initially assumed to be a new species of Capanea by Hans Wiehler when
it was collected and appeared in a photograph in the horticultural journal The Gloxinian (McDowell 1995).
Images of K. hypertrichosa also appeared in the Gesneriad Journal as a new species of Capanea in a report of
a collecting expedition to Ecuador (Dunn 1997). The species was assumed to be a member of this formerly
recognized pane ARN e Ge woolly pubescence the shape of the corolla, and its epiphytic habit.

is also abundant (cf., field ci É Clark 6298). The two species often grow E by-side and e
them apart vegetatively is challenging.
The species described here is remarkable in that it has been collected and specimens annotate d as be-
longing to Monopyle or Capanea, but not Kohleria. The correct placement of this new species has perplexed
many Gesneriaceae workers because of its habit (facultative epiphyte instead of the more typical terrestrial
habit in Kohl ena Gees E pune on the outer surface of the corolla Ee typical of Capanea); and
.
of Monopyle) The key sy y tor recognizing traditional
str ongl
Kohleria is a ERU dehiscing by a single dorsal slit from apex to base (Biss 1D and 2G). The presence of this
type of fruit in this species was unknown until it was observed and photographed in 2001 (cf., field collec-
tion J.L. Clark 6288). Many other collectors (e.g., Tirado and Hoover) had documented this new species in

flower, but not in fruit, thus making it a difficult species to place without molecular data. The presence of
a bilobed stigma is a SR ee that K. LL adn shares SH most dani adi Á EE
stigma is present in À y in the two traditionally g d species of Capanea
that were eg — in Kohleria o et P 20053).
Another morphological feature of many species in Kohleria, which is also present in K. hypertrichosa, is
the presence of a ventricose apical pouch on the lower side of the corolla. The ventricose pouch in K. hyper-
trichosa is sometimes obscured a d: and on pressed herbarium collections (e.g., the pouch was not

Th t of K. hypertrichosa is al ly supported by molecular data from the nuclear
ribosom al DNA internal t ] region, the ala DNA trnL intron and trnL-trnF intergenic
spacer region (Roalson et al. 2005b). One of t] that appeared in the pl y published by Roalson
et al. is a tissue sample from silica Ln dried leaves of a paratype of K. eri hasi (cf., field collection J.L.
Clark & R.W. Dunn 2446). The sp llection is noted in Roalson et al. (2005b) as, “Kohleria sp. nov. 2446”
where it was shown as being strongly supported as the sister taxon to Kohleria villosa (Fritsch) Wiehler.

abundant sometimes covering trees and trailsides, especially in the Mirador de las Golondrinas, a private
reserve managed by Fundación Golondrinas and the Gualpi area near the Reserva Awá (collections exist
both inside and outside the Territorio Awá). No collections of Kohleria hypertrichosa have been made outside
of the Carchi and Esmeraldas provinces, but it is likely to also occur in the adjacent Department of Nariño,
Colombia where limited recent botanical exploration has taken place.
Etymology.—The epithet hypertrichosa is derived from the congenital condition of generalized “Hyper-
trichosis,” the medical term referring to a condition of excessive growth of body geg in humans. The condi-
tion is commonly known as “Werewolf syndrome” which comes from a mythological werewolf of which the
person is completely covered in hair or fur. Although not Ge PINE in ión: the plant species
is known among horticulturalists as “Chewbacca,” for the famous hairy biped character (^Wookie") from

RESUMEN
Se describen e ilustran d peci para Sur América papi Md G. chaparensis. Guadua incana del suroriente de
Colombia, crece en el pie d te del tiente oriental d e los Andes, y G. chaparensis de Bolivia, se localiza en el
Distrito Biogeográfico Amazónico del Chapare. Con base en evidencias morfológicas, G. incana Gs G. MU CAD se relacionan entre
si y también con Guadua weberbaueri, la cual se lectotipifica aquí. Además, se hace otras especies afines y se
incluye clave para identificación.
During a 1987 field trip to Caquetá and Putumayo, Colombia (Colciencias-Inciva Project No. 2108-07-009-85),
sterile specimens of a new species of Guadua (Londoño & Quintero 144 & 214) were collected. A living rhizome
was brought to the bamboo germplasm bank of the Juan Maria Cespedes Botanical Garden in Tuluá, Valle
del Cauca, Colombia, and after 14 years in cultivation (1987—2001), accessions Londoño 144 & 214 flowered
and made possible their identification.
Because of the absence of flowering material in the majority of woody bamboo herbarium specimens
(in part, a result of their long flowering cycles), several species of bamboo are described from vegetative
material alone, e.g., Eremocaulon setosum Londoño & L.G. Clark, Chusquea riosaltensis L.G. Clark and Ch.
caparaoensis L.G. Clark (Londoño & Clark 2002a; Clark 1992). Vegetative characters such as culm leaves,
buds, branches and rhizomes have been utilized to delimit many new species (McClure 1966; Judziewicz
et al. 1999; Soderstrom & Young 1983). We waited 14 years for the opportunity to describe G. incana with
flowering material, but for the new species from Bolivia, G. chaparensis Londoño & Zurita, we decided to
describe it on the basis of sterile material alone, in order to provide a name for this distinctive species.
In addition to the vegetative and reproductive characters used to delimit G. incana, the genetic AFLP
analysis done by Marulanda et al. (2002) reported a clear genetic differentiation between G. incana and G.
angustifolia (accessions, varieties and biotypes), and also between G. incana and Guadua uncinata Londoño
& L.G. Clark (2002b), a species that is sympatric with G. incana. This genetic result helped corroborate the
diagnostic morphological features that identify Guadua incana as a new species.
Guadua chaparensis was collected by the second author in central Bolivia. It occurs not only in the type
locality (Comunidad Israel) but in various communities such as Capinota, Hermanos Ledesma, Agua Rica,
24 de Septiembre, Monte Sinaí, Villa Jerusalen, Villa Imperial, Valle de Sajta, Valle Ivirza, Villa Nueva, Alto
San Pablo, Tarija and Puerto Aroma, all of them in the Chapare area.
The two new pecies, G. incana and G chaparensis, are clearlv ref to Guadua | 1on their] ked
rhizomes, white bands on the culms, thorny branches, enla culm leaves, and, in the case of E incana,
pseudospikelet structure with winged-keeled palea (Judziewicz et al. 1999). Both species are closely related,

grow in lowland tropical rain forests, and appear to be endemic to the localities in which they were collected.
Both are also utilized by local communities for corrals, fences, water conduction and light rural construction.
Guadua weberbaueri, the taxon most closely allied to the two new species, was described by Pilger
(1905), who selected as the holotype number 4562 collected by the German botanist August Weberbauer
(1871-1948) in Moyobamba, Perú. As with many other collections by Weberbauer, the type chosen by
Pilger and deposited in Berlin (B) was destroyed during World War II. In 1991, the first author visited the
herbarium of the Universidad Nacional Agraria, La Molina (MOL) in Lima, Peru, and found a complete du-
plicate of Weberbauer 4562. This isotype, which we have selected to serve as the lectotype, includes a foliage
leaf complement and one inflorescence branch.
Morphological study reveals that Guadua weberbaueri Pilger, G. ol usd Sege and e sarcocarpa
Londoño & Peterson (1991) share several features with each other and the two species, forming
the basis for a group within Guadua, here recognized informally as the G. weberbaueri eos (Table) The
following combination of characters delimits this group: a) culms erect at the base with the apical portion
leaning on or pendent from trees; b) internodes hollow, with walls up to 1.5 cm thick, elongated up to 90 cm;
c) culm leaves with persistent blades, these 1/4 to 1/5 as long as the sheaths; d) culm leaves with canescent
inner ligules; e) synflorescences terminating in leafy or leafless branches with capitate coflorescences in
the earliest state of development; f) pseudospikelets with wide-winged palea keels (0.8 to 2.5 mm); and g)
ovaries fusoid in shape.
These five species, Guadua weberbaueri, G. sarcocarpa, G. incana, G. chaparensis and G. tagoara, grow
in very humid, lowland forests and they have in common the presence of water inside of the hollow in-
ternodes. Herbarium labels from Guadua sarcocarpa (Calderon & Soderstrom 2348-US#2810196 and Smith
5275-US#3080541), the description for G. tagoara in Londoño and Clark (2002b), and Louton et al. (1996)
for G. weberbaueri reported the presence of internodes filled with water. This internal water phenomenon
seems to be associated with very high relative humidity and a high water table. Why water accumulates
inside the internodes is still uncertain. It may occur after strong changes of temperature that break tissues
allowing water to leak into and accumulate in the lumen.
A key to the species of the G. weberbaueri group based on vegetative characters is presented here.

Etymology.—Ihe specific epithet refers to the evidently canescent abaxial surfaces of the culm leaf
sheath when young
Distribution and habitat. —This species occurs in southern Colombia, in the departments of Caqueta
and Putumayo, in the foothills of the eastern side of the Cordillera Oriental de los Andes, at elevations
between 280—1200 m. It grows in the interior of very humid mountain forests, along creéks, but does not
form dominant clumps and is generally uncommon.
Common name.—Guadúa (with accent).
Uses.—Farm fences and light rural infrastructure.
Phenology and Fruiting.—The flowering behavior of bamboos is still unexplained and mysterious. The
factors that switch a bamboo plant from a vegetative to a flowering state are not fully understood (Janzen
1976; Judziewicz et al. 1999). Guadua incana can flower continuously for at least 2-3 years and without
dying. A flowering culm in this species is leafy and the production of fruit and seedlings is uncommon. As
in G. weberbaueri, only a few culms from the whole clump flower at any given time. Despite this research,
it is still impossible to establish its regular flowering cycle, but we know that it takes at least more than 14
years.
The BEE of mature fruit in G. incana is scarce. Only one fruit was found in a functional i
from tl iddle part of t] lospikelet. This floret falls along with the rachilla, lemma and }
to the base as in other ree species, e.g., G. chacoensis (Rojas) Londoño & Peterson (Londoño & Peterson
1992). The dorsal surface of the fruit has a conspicuous linear hilum, purplish in color, extending down the
| | Z I ta Al . Er | £ fe Lo E A 31
length of the fruit and the ventral surface has a prominent embryotegium. The embryo is 1/5-1/6 of the
length of the whole fruit, and is located at the base of the ventral surface. The indument of the fruit is very
peculiar, with the upper 1/9th e MESE the fruit is strigillose and covered with a whitish waxy coating.
Pseudospikelet.—The p tisa phy for Guadua + Eremocaulon within the subtribe
Guaduinae (Ruiz et al., in tess) and among estaria woody bamboos is also found only in the genera
Elytrostachys McClure, Amta Soderstrom & Londoño, and Atractantha McClure, all of them in the sub-
tribe Arthrostylidiinae. The term is used to describe synflorescences of woody bamboos that rebranch to
produce successive orders of spikelets (McClure 1966; Judziewicz et al. 1999; Young & Judd 1992, Bamboo
Phylogeny Working Group 2005). According to Londoño and Clark (2002b) the following structures are
all homologous at some level: subtending bracts, gemmiparous bracts, glumes, and both sterile and fertile
lemmas. However, this is not the case with the prophyll, which is homologous to the palea (Stapleton 1997;
Bamboo Phylogeny Working Group 2005). In G. incana, the most proximal bract to the prophyll gives the
impression of being the prophyll itself, because the midnerve is similarly keeled and conspicuously asym-
metrical, the apex bifurcate and shortly mucronate, and always fertile, enclosing a bud (Fig. 1: HD The
prophyll when present is conspicuously ciliate but frequently the hairs rub off in situ.
Affinities —Guadua incana is most similar to G. weberbaueri Pilger and G. sarcocarpa Londoño & Peter-
son. The three species share the following characters: a) triangular culm leaves with the margins slightly
discontinuous at the junction with the blade; b) culm leaf blades 1/4 to 1/5 as long as the sheaths, adaxially
pubescent and with a strong mucro at the apex; c) adaxial surfaces of the lemmas See on their upper

halves; d) paleas with pubescent ; e) conspicuous winged |
an acute apex; f) lodicules strigilllose in the upper third; and g) ovaries and styles antrorse-hispidulous.
However, G. incana differs from G. weberbaueri and G. sarcocarpa in having (1) blade and sheath of the
culm leaves conspicuously distinguished by color and pubescence (vs. inconspicuously distinguished by
color and pubescence); (2) subglabrous adaxial surfaces of the leaf blades (vs. entirely glabrous); and (3)
strigillose sulcus of the palea (vs. pubescent) (Table 1).
Guadua incana differs from G. sarcocarpa in its (a) culms erect at base, arching apically (vs. erect at base,
then branching above and reaching over trees for support); (b) white-greenish and hairy culm leaves when
young, (c) conspicuously ciliate overlapping margin of the foliage leaf sheaths, (d) shorter and narrower
pseudospikelets, (e) the winged palea keels marginally ciliolate, and (f) dry caryopsis fruit. It differs from
G. weberbaueri in its (a) longer pseudospikelets, (b) smooth and papery margins of the lemma, (c) abaxially
BEE put basally SEHEN, ciliolate Map ps iet Ge x
heath margins, (b) similar pseudospikelet
size, (c) gemmiparous bracts with the miden strongly ed (d) the lemma margins exceeded by the
winged-keels of the palea, (e) a palea with two conspicuous winged-keels and a pubescent sulcus between
nerves; and (f) a fusoid antrorse-hispidulous ovary (Table 1).
According to the molecular analysis done by Marulanda et al. (2002), G. incana shows a wide genetic
distance in relation to G. angustifolia and greater genetic similarity with G. amplexifolia which shares a canes-
cent indument on the abaxial surfaces of the culm leaf sheaths, the inner ligule extending from margin to
margin and the strong mucro at the apex of the culm leaves; DNA isolation for G. weberbaueri, G. sarcocarpa
and G. tagora, the three closely allied species, was not successful in the above mentioned research.

Etymology.—Th itl to the Amazon biogeographical district of the Chapare
River, Cochabamba, Bolivia where this species is found.
Distribution and habitat. —Known only from the department of Cochabamba, Carrasco, Chapare, below
900 m of elevation, with a total annual precipitation estimated to be 6000 mm and a median temperature
of 25°C. It occurs along rivers and creeks, such as the Sajta and Ivirza, and is associated with Hura crepitans
L., Guadua sarcocarpa Londoño & Peterson, Mendoncia aspera Nees, Cecropia sp., and Costus sp.
Common name.—Tacuara hembra or tacuara.
Uses.—Guadua chaparensis culms are used by local communities to make fences, walls, water contain-
ers, and for conducting water.
Affinities —Guadua ch j t closely resembles G. tagoara (Nees) Kunth and G. incana. They share
a culm that is whitish-green ¡nen young to dark green at maturity; er and SE nua 20
to 80 cm long with walls less than 15 mm thick; coriaceous culm leaves wit ight to slightly
curved at the middle, abaxially with a canescent indument, looking like wool and easily dead ed with the
margins densely ciliate; a eae ee page as leaves in complements of 5 to 8(-10); foliage
leat sheaths bearing a patch of I the apex; pulvinate pseudopetioles that
are abaxially glabrous; and a prominent and vello midnerve and primary nerves on the abaxial surfaces
of the foliage leaf blades (Table 1).
Although they share several characters, Guadua chaparensis has a combination of vegetative features
that distinguishes it from G. incana and G. tagoara even in the absence of inflorescences. The most evident
ones are (a) the sericeous abaxial surface of the culm leaf sheaths, covered by one type of hair (vs. pubes-
cent, covered by two or three different types of hair and forming a hispid surface); and (b) the absence of
fimbriae at the summit of the foliage leaf sheath (vs. present) (Table 1). With respect to G. weberbaueri and
G. sarcocarpa, G. chaparensis also shares several vegetative characters listed in Table 1.

ua herbarium material of a distinctive species was collected in the Sierra Martin Garcia (by W.S.
Judd, in 1992 and 2006) and Sierra de Baoruco (by T. Clase, in 2001). It is now evident that these collections
represent an undescribed species of Tetrazygia (Miconieae, Melastomataceae), which appears to be closely
related to T. longicollis Urb. & Cogn. and T. elaeagnoides (Sw.) DC. These plants are described here, provided
with the name T. paralongicollis, and compared morphologically with the above mentioned species.
Recent molecular-based phylogenetic analyses (F. Michelangeli, R. Goldenberg, W. Judd, and others;
unpublished data) indicate that Tetrazygia, a genus of ca. 20 species (Judd & Skean 1991; Liogier 2000), is
not monophyletic as traditionally circumscribed. The species of Tetrazygia Rich. are intermixed in prelimi-
nary cladograms with members of SE other pe of Miconieae, especially Pachyanthus A. Rich. and
Calycogonium DC., two genera that y Antillean in distribution, asis Tetrazygia. Clarification
of generic limits within this sidade of the EEN i.e., an Antillean complex (see Michelangeli et al.
2004, 2008) is beyond the scope of this paper, but we note fat T. elaeagnoides, which has 4-merous flowers
(as does T. longicollis and the species described herein), in preliminary cladistic analyses does not appear
to be closely related to the species with 5- or 6-merous flowers, such as T. bicolor (Mill.) Cogn., T. coriacea
Urb., and T. lanceolata Urb.

Distribution and habitat —Tetrazygia paralongicollis is restricted to the southern part of the Dominican
Republic where it has been collected only in the Sierra de Baoruco and Sierra Martin Garcia (Fig. 2), from
720—860 m. In the Sierra de Baoruco it occurs in Pinus occidentalis Sw. forests, while in the Sierra Martin
Garcia it grows in moist montane forest (on limestone). In the Sierra Martin Garcia, associated melastomes
include Calycogonium hispidulum Cogn., Miconia laevigata (L.) DC., Sagraea fuertesii (Cogn.) Alain, Tetrazygia
elaeagnoides (Sw.) DC., and T. longicollis Urb. & Cogn.
Etymology.—Ihe specific epithet highlights the purported close relationship of this species with Tetra-
zygia longicollis, especially as evidenced in the characteristics of its flowers and fruits.
Vegetative anatomy.—Stem, leaf, and petiole anatomy were assessed in material of Tetrazygia paral-
ongicollis, i.e., Judd 8148 (FLAS) and Clase & Delprete 3035 (FLAS), and leaf and petiole anatomy were as-
sessed in material of T. longicollis, i.e., Judd 6656 (FLAS) and T. elaeagnoides, i.e., Judd 6553 (FLAS) using the
phloroglucinol-hydrochloric acid technique outlined by Howard (1974). As is typical of Melastomataceae,
me stems =o eS "eue a ring of xylem with phloem das both externally and internally

fed, and petivásculi fibers are lacking, but there are scattered lignified idioblasts in the inner portion of
the cortex, which may have a protective function (because they surround the stele). Druses also are present
in the cortex. The nodes are unilacunar/unifascicular, but the vascular bundle divides within the petiole
base, forming several bundles in the petiole. The petioles (sectioned at their midpoint) of all three species
exhibit a U-shaped pattern composed of 7 to 11 vascular bundles, with the individual bundles composed
of xylem surrounded by phloem. The ground parenchyma is unlignified, but in T. paralongicollis there are a

The leaves of all three species have dorsoventral blades with an epidermis, palisade and spongy ——

present in the parenchyma associated with the midvein vascular bundles of T. paralongicollis and T. longicollis,
while these cells are lacking in T. elaeagnoides. The abaxial leaf surface of all three species is covered with a
thick layer of stellate hairs, which are variably lignified. As with the petiole, the parenchyma of the midvein
of T. elaeagnoides contains very abundant druses. Druses are present in the lamina of all three species, with
these iun placed below the epidermis in either the palisade or spongy mesophyll.

DISCUSSION
Tetrazygia paralongicollis is most similar to T. longicollis (incl. T. brevicollis Leonard). This is especially seen
in the form of its flowers and fruits, i.e., 4-merous, with conical-terete external calyx lobes, broadly trian-
gular internal calyx lobes, ovate-obovate, white petals, stamens with ovate-elongate anthers, an ellipsoidal

ovary (only slightly 4-lobed) and with the placentas inserted into locules, T-shaped in cross section, and
globose-ellipsoid berries with strongly constricted hypanthium. However, it is consistently differentiated
from T. longicollis by its globose-stellate hairs, i.e., with branches radiating in all directions from a globose
central region (vs. flattened-stellate hairs, i.e., with branches more or less radiating outward from a central
region), the tertiary veins usually connected by reticulate quat y veins, i.e., only occasionally separated
by composite-intertertiary veins (vs. tertiary veins usually separated by composite-intertertiary veins, thus
making the leaf “tertiary” veins appear to be closer together than they actually are), and external calyx lobes
that are ca. 1.2 mm long (vs. variable in length, ca. 1-5 mm long). Tetrazygia paralongicollis is also quite
similar to T. elaeagnoides, especially in the morphology of its stellate hairs and in the pattern of venation
of its leaves. Tetrazygia paralongicollis is easily distinguished from this species by its hypanthia (and fruits),
which are globose-ellipsoid and only very slightly 4-lobed when in flower, becoming unlobed in fruit (vs.
subglobose and strongly 4-angled), placental form, i.e., the placenta extended into the locule and T-shaped
in cross-section (vs. elliptic in cross-section), and the presence of lignified idioblasts in the parenchyma of
the petioles (vs. lignified idioblasts lacking). In addition, many plants of T. elaeagnoides have shorter exter-
nal calyx lobes, e.g., ca. 0.2-0.4 mm long, but in some plants Ge B BE as long as 1.6 mm. Plants of T.
le, elon gate, multiseriate
paralongicollis from the type locality differ from both of tl
hairs intermixed with the globular-stellate hairs on their stems, abaxial leaf Seet kal margin (in associa-
tion with the teeth), inflorescence axes, and hypanthium. The plants of the Sierra Martin Garcia, however,
lack these hairs, but these plants (unfortunately, only collected in sterile condition) are considered within
T. paralongicollis because their leaf shape, venation, and stellate-hair morphology closely match that of the
type specimens. It is noteworthy that the leaves of the Sierra Martin Garcia population are frequently larger
than those of either T. longicollis or T. elaeagnoides. This new species occurs with both T. longicollis and T.
elaeagnoides in the Sierra Martin Garcia, but no intermediate plants were seen in that region. Only T. longi-
collis, however, is known from the Sierra de Baoruco, in the vicinity of the type EES
Tetrazygia paralongicollis, exhibiting a distinctive combination of | characters, satisfies the
expectations of the morphological-phenetic (Judd 2007) and diagnostic (Wheeler & Platnick 2000) species
concepts.
The description of Tetrazygia paralongicollis brings the number of species of Tetrazygia known from
40 | PR | A a | Li sta fTexas 2(
Hispaniola to eight (Liogier 2000), given that we consider T. urbaniana (Cogn.) Croizat ex Moscoso to be
a synonym of the morphologically variable T. tuerckheimii (Cogn.) Ekman & Urb. All the other species of
Tetrazygia show fairly broad geographical distributions on the island compared to T. paralongicollis.

ABSTRACT
Cuatresia amistadensis, a new species from Costa Rica and Panamá is described and illustrated, and its taxonomic relationships are
discussed.
Key Wonps: Solanaceae, Cuatresia, Talamanca, Parque Internacional La Amistad, Costa Rica, Panamá.
RESUMEN
Cuatresi istadensi para Costa Rica y Panamá, es descrita e ilustrada, y se discuten sus relaciones taxonómicas.
PALABRAS CLAVE: Solanaceae, Cuatresia, Talamanca, Parque Internacional La Amistad, Costa Rica, Panamá.
La familia Solanaceae se distribuye en áreas templadas, tropicales y subtropicales, pero su mayor represen-
tación se encuentra en el trópico, con ca. 95 géneros y 2200 especies (Nee 2004). El género Cuatresia Hunz.
(Hunziker 1977) de origen Neotropical, posee 12 especies publicadas y 6 para Costa Rica (A.Soto en prep.)
se distingue del género Witheringia L'Hér. por sus anteras ee y pe no ados (Hunziker
1987); un carácter importante de notar es que el género Cuatresia se distingue de otros g relacionados
por su patrón de estivación induplicada (N. Sawyer, com. pers.).
En el trabajo de campo para el proyecto 'Baseline tools for management in PN La Amistad (Costa
Rica/Panama), realizado en el Parque Internacional La Amistad entre Costa Rica y Panamá, se recolectó la
siguiente especie de Cuatresia, la cual es descrita a continuación.

Fenología.—Se ha recolectado con flores de Diciembre a Mayo, y con frutos de Febrero a Marzo.
Etimología.—El epíteto de este taxón está dedicado al parque internacional La Amistad, ubicado entre
Costa Rica y Panamá (PILA).
Cuatresia amistadensis es fácilmente distinguible por poseer pedúnculos péndulos, muy largos y del-
gados, hasta 10.5 cm, además con hojas dimidiadas secando de un color café claro. Esta especie se podría
confundir con Witheringia cuneata (Standl.) Hunz., ya que comparten un rango de distribución geográfica
similar y porque tienen pedúnculos alargados, pero en W. cuneata son más cortos y robustos, miden como
máximo 6 cm. Las diferencias entre ambos taxones se mencionan en el Cuadro 1. Otra especie muy similar
es Cuatresia plowmanii A.T. Hunziker, que se distribuye en el Sur de Colombia y Ecuador, el largo de los
pedúnculos es similar pero los lobos de la corola en C. plowmanii son triangulares vs. oblongo—acutados,
están divididos por < 1/3 del largo de la corola vs. divididos por > 1/3 del largo; además la inflorescencia es
una cima unípara vs. compuesta por dicasios y las hojas presentan una venación terciaria muy continua y
d otras diferencias entre estos taxones se anotan en el Cuadro 1.

The infrageneric classification of Baccharis was recently worked for Giuliano (2001, 2005) to Argentina,
Giuliano and Nesom (2003), and by Müller (2006) to Bolivia. Müller used the name “Baccharis genistelloides
Group” for the species belonging to Baccharis sect. Caulopterae, which consists of perennial herbs, subshrubs,
and shrubs with 2-3- alate stems, normal to squamiform leaves, capitula sessile and arranged in spikes or
vithout paleae, and achenes (5-20)-ribbed and glabrous or papillose. Section
Camlonienies is ded. to South America.
During a taxonomic revision of Baccharis sect. Caulopterae of southern of Brazil two new species were
recognized with morphological characteristics that distinguish them from all other species.

In EE of a DE of the genus Cotoneaster two new species and one new series have come to
light, all in the subgenu Cotoneaster, and are described | t] for use in the upcom-
ing treatment of the genus in the Flora of North America.

Shrubs, small t lium sized, often densely branched. Leaves deciduous or semi-evergreen, subcoriaceous
or coriaceous, lower surface tomentose, upper surface rugose. Inflorescences 1-20-flowered; the fertile
shoots 10-70 mm long. Flowers with hypanthium tomentose-pilose. Anthers mostly white. Fruit orange-
red. Pyrenes (2—)3—4(—5). Fruiting mid to late season.
Cotoneaster series Sterniani includes five species: Cotoneaster elegans (Rehder & E.H. Wilson) Flinck
& B. Hylmó; C. induratus J. Fryer € B. Hylmó; C. insculptus Diels; C. qungbixiensis J. Fryer & B. Hylmó; and
C. sternianus. Members of the series Sterniani are distributed in Asia from China (Yunnan, Xizang (Tibet),
Sichuan) to Myanmar.
Species belonging to series Sterniani are closely related to those of series Franchetioides, which differ
in having evergreen leaves, with the upper leaf surface grayish-green, anthers mauve, pink, or purple, and
pyrenes 2 or 3 per fruit.

Phenology and ecology.—Flowering June to July; fruiting October to November. Natural populations in Yun-
nan Province, China, are in full sun on rocky slopes over calcareous bedrock. In cultivation, Cotoneaster
qungbixiensis is hardy to -18°C, and is an attractive shrub with good autumn fruit color.
Cotoneaster qungbixiensis is named for the type locality on Cangshan Mountain in Yunnan. It is closely
related to C. sternianus, which differs in having leaves that are evergreen, thicker and coriaceous, broadly
elliptic to broadly ovate with apex acute or acuminate and lateral veins in 4—6 pairs.

Shrubs, 1.5-2 m tall. Branches erect and arched; branchlets distichous, maroon and minutely verruculose,
initially pilose-strigose. Leaves deciduous, chartaceous or subcoriaceous, on sterile shoots elliptic, often
broadly so, 15-25 x 11-25 mm, base cuneate or obtuse, apex acuminate or acute, lower surface whitish
tomentose-pilose, upper surface dark green, dull, strigose, veins 3(4) slightly impressed pairs; petiole 3—4
mm long, strigose. Inflorescences 2—5 flowered; fertile shoots 20-40 mm long, with mostly 4 leaves; pedicels
2-6 mm long, strigose. Flowers (including hypanthium) 5-6 mm long. Hypanthium turbinate, densely
strigose; sepals cuspidate or acuminate, densely strigose, membranous, reddish-brown, and glabrous near
margin, margin villous. Corolla closed; petals erect-incurved, pink with dark red base and white and pink
border. Stamens 14-17, filaments dark red or red with pink apex; anthers white. Fruit rich red, intensely
shiny, narrowly obovoid, 10-11 mm long, sparsely pilose, calyx lobes infolded, appressed, densely pilose.
Pyrenes 2—3—4 (ca. 1096—6096—3096), persistent style on abaxial surface, 2/3 from base.

Phenology and ecology.—Flowering June; fruiting September to October. Little is] bout its habitat
or associates where it is native in China, in Yunnan and Sichuan Provinces. In cultivation it is hardy to -21°C.
Cotoneaster floridus is frequently found in cultivation as C. rubens hort. non W.W. Sm., a misnomer
under which it was distributed as seed from the Royal Horticultural Society Wisley Gardens in England.
It can also be found under the name e dielsianus var. rubens hort. Unfortunately, Professor Yü's collection
bers have | confused in cultivation, hence various species of Cotoneaster can sometimes be found
SE a single collection number.

INTRODUCCIÓN
Meliosma Blume (Sabiaceae) es un género de árboles y arbustos nativos de Asia y América tropical. En el
Neotrópico comprende ca. 70 especies, y se encuentra distribuido desde México hasta Brasil, Bolivia y las
Indias Occidentales (Gentry 2001; Morales 2003; Arbeláez 2004; Cornejo, unpubl.). En América del Sur
Meliosma se encuentra concentrado al norte de los Andes (Gentry 1980, 1986, 1992, 2001; Cornejo 2006),
pero el conocimiento taxonómico de muchas de las especies andinas de este género es aún limitado debido
a la falta o insuficiencia de especímenes con flores en los herbarios. En la mona grata de Meliosma para Co-
oia Geen & EE SE se trataron 12 especies, seis de | f nuevas para la ciencia
Post han sido descritas para la flora de este país (Cuatrecasas & Idrobo
1988; Cuatrecasas 1988; Idrobo 1988). Al revisar el material colombiano, encontré la siguiente novedad.

ls MA MN es una s las especies ne este género que posee las hojas mas grandes en América
del Sur. Vegeta! a M. donnel i, distribuida en Costa Rica y Nicaragua (Gentry 2001;
wl
Morales 2003), pero facilmente se diferencia de ésta por tener las hojas con los peciolos más largos (1,5-3,5
vs. 0,3-1,1 cm), las flores pediceladas están laxamente dispuestas a lo largo de las ramificaciones (vs. sésiles,
densas), los pétalos internos son más pequeños (0,7—1 vs. ca. 1,8 mm), éstos poseen el ápice bífido (vs. en-
tero) y el estilo si presente es muy corto (ca. 0,1 vs. 0,8-1 mm, linear). Por sus flores pediceladas con pétalos
internos bífidos, distintivamente más pequeños que los estambres y estilo muy corto, Meliosma antioquiensis
es parecida a la especie colombiana M. ellipticifolia Cuatrec. Sin embargo, esta última difiere por presentar
láminas foliares mucho más pequeñas (7-12 x 3,5-5 cm), con menor número de nervios laterales (9-11),
60 j t tanical h Insti Texas 2(
peciolos más cortos (0,6—1 cm), inflorescencia más corta (8—12 cm), y flores con sépalos más grandes (1,5—2
mm). Por sus grandes láminas foliares Meliosma antioquiensis es algo similar a M. itatiaiae Urb., restringida
a las tierras bajas de Brasil, pero ésta presenta hojas con peciolos más cortos (ca. 1 cm), láminas con base
redondeada hasta subauriculada y margen fuertemente aserrado, con curvos dientes corniculados e inflo-
rescencias opuestas a las hojas, más densas, que portan flores sésiles.

Capparis L. s.s. es un pequeño género de distribución casi estrictamente Holárctica, centrado alrededor de
su tipo Capparis spinosa L., la especie proveedora de las conocidas alcaparras y alcaparrones comestibles,

un género de dee enemies de Australia, antes que a Md Capparis del Nuevo Monde (Hall et al.
2002: 1839; Inocencio et al. 2006: 123). Basado en gicos, Hutchinson (1967: 307) concluyó
que más de un género debía de ser reconocido en Capparis s.l., y propuso su reordenamiento genérico. 5in
embargo, debido a la falta de un conocimiento satisfactorio y a las muy incompletas colecciones de las espe-
cies de esta familia en América hace 40 afios atrás, el reordenamiento genérico de Capparis s.l. propuesto
por Hutchinson prácticamente ha sido ignorado.
En aiios recientes, al realizar los estudios de Capp para Flora? | y Flora de Ecuador
(Iltis & Cornejo, ms. sometido; Cornejo & Iltis, en prep.), con base a las colecciones Gees relativa-
mente más completas obtenidas en las pasadas décadas, así como meticulosas Io en pe ha
llegado a ser claro que los Capparis s.l. de América son divisibles en varios géneros Cornejo
& Iltis 2006, 20083, b, c; Iltis & Cornejo 2007, 2008).
En los Capparis s.l. de América, el tipo de pubescencia es un caracter m útil, estable, bien definido y
confiable (Iltis et al. Po Desde este pue Es vista, los Capparis sl dividen en dos grandes
grupos, que están j t ados con el número cromosómico: 1) los de ec simple
o glabros, y 2) los de pul ia peltada a estrellada, candelabra o dendroidea (Iltis & Cornejo, manuscrito
sometido). Entre los Capparis s.l. de pubescencia simple o glabros están "v géneros Cynophalla (DC.) J. Presl
y Capparidastrum Hutch. I pect le e ás un nuevo género
de este grupo están en proceso (Cornejo & Iltis 2008b, C). Ene esta publicación se presentan
dos nuevos géneros sudamericanos pertenecientes al grupo de las Capparaceae de hojas y pubescencias
simples.
Para obtener las imágenes de polen se tomaron prefloraciones justo antes de la antesis de los espe-
címenes respectivos (Vogel 483, de Michel 156, Gentry et al. 10992, Santos et al. 2066, Mori & Kallunki 5379) que
reposan en el herbario WIS y fueron enviadas a la Estación de Agricultura Experimental de Kansas (Kansas
Agricultural Experiment Station). Éstas prefloraciones fueron suavizadas en KOH al 10 % y acetolizadas
de acuerdo con Erdtman (1960). Las muestras de polen fueron dividas en dos grupos para ser estudiadas
en el microscopio de luz (ML) y en el microscopio electrónico de barrido (SEM). Para ML, las muestras de
polen fueron montadas en un gel de glicerina y examinadas con un microscopio óptico Zeiss Universal de
campo brillante. Para SEM, las muestras de polen fueron suspendidas en agua destilada, pipeteadas sobre
un portaobjetos y secadas al ambiente. Las muestras fueron rociadas y recubiertas con una película de oro-
paladio y examinadas con un microscopio electrónico Eteck Autoscan SEM, en la Estación de Agricultura
Experimental de Kansas. Las placas con los respectivos granos de polen y las imágenes SEM reposan en el
herbario WIS de la Universidad de Wisconsin, en Madison

las, dimórficas, escuamiformes y carnosas, éstas son una proyección de la capa carnosa del tejido nectario
que cubre al receptáculo. Las escamas mayores son transversalmente SCH geg hasta semicirculares,

Estambres exsertos, ca. 20-50, insertos al mismo nivel sobre un grueso andróforo carnoso (en vivo), éste es

Éste se et y distingue de codos] los demás gé (Hutchinson 1967) tradicionalmente
tratados en Capparis s.l. por presentar: 1) Escamas nectarias dimórficas (vs. nectarios [e.g., Cynophalla],
escamas nectarias [Beautempsia] o apéndices nectarios [e.g., Capparicordis], siempre isomórficos); 2) semi-
llas x subglobosas (vs. cocleadas o reniformes hasta elípticas); y, 3) embriones con cotiledones separados,
Cornejo et al., N South A i fC 65
extremadamente anisocótilos, muy distintos en tamaño y forma entre sí, con un cotiledón mayor compacto,
especializado para almacenar (Fig. 1D), y un cotiledón menor muy reducido o ausente, único en las Cap-
paraceae del Nuevo Mundo. Éstos han sido discutidos en detalle e ilustrados por Franceschini & Tressens
(2004 [ver Capparis speciosa]).
Por la apariencia externa de sus frutos y el color blanco marfil de los embriones de sus semillas, Ani-
socapparis superficialmente se asemeja a algunos miembros de Capparidastrum Hutch. (e.g., Caparidastrum
petiolaris [Kunth] Hutch., comparar con Cornejo & Iltis 2005a: 158, fig. 2C [tratado como Capparis peti-
olaris]). Pero además de los tres caracteres anteriormente mencionados, Anisocapparis también se diferencia
de Capparidastrum por tener un cáliz notoriamente anisosépalo, con aestivación decusada-imbricada (vs.
cáliz isosépalo, frecuentemente 1-seriado) y granos de polen con una ornamentación finamente reticulada
(Fig. 4, vs. tectada-espinulosa [Fig. 7] o tectada-perforada). Otras diferencias menores de Anisocapparis en
comparación con Capparidastrum son la presencia de láminas foliares de menores dimensiones, 3-8 cm
(vs. usualmente 10-50 cm), y una densa Tue en la base de los filamentos de los estambres externos
(vs. filamentos glabros), cuya función es desconocida. Bajo el estereoscopio se ha observado que ésta retiene
granos de polen, por lo que se presume podría estar relacionada con la polinización.
Entre las Capparaceae de América, el tipo de cáliz anisosépalo que presenta Anisocapparis, con los
sépalos dimórficos dispuestos en dos series, decusados-imbricados desde la prefloración, cuyo par de sé-
aie EE externos es pa menor dimensión en comparación con el par de sépalos internos, es
ola Ha (Iltis & Cornejo 2005, tratado como Capparis subg. Cynophalla). Debido a esta
similitud, la especie SH E EN (Capparis speciosa) fue originalmente descrita como perteneciente
a las “Cynophalla” (Grisebach 1879: 18). Pero Anisocapparis fácilmente se diferencia de Cynophalla por la
ausencia de las características glándulas nectarias extraflorales, dispuestas en las axilas de las ramas termi-
nales e inflorescencias; también por la diferente estructura y disposición de los nectarios florales (éstos en
Cynophalla son siempre E dci hasta un pee cóncavos y dispuestos + horizontalmente sobre el
receptáculo), y por el polen de iculada (vs. tectado-espinuloso en Cynophalla). Además,
los pepos globosos a AA con semillas subglobosas, D de cotiledones separados con un
1
cotiledón mayor muy desarrollado y compacto, est ma , de color blanco y no clorofílico
de Anisocapparis, contrasta grandemente con los frutos capilares, nas, con semillas elipsoideas,
isocótilas, de embriones de cotiledones delgados, convolutos, verdes y clorofílicos de Cynophalla (véase en
Franceschini & Tressens 2004 [Capparis speciosa vs. C. flexuosa L. y C. retusa]; Iltis & Cornejo 2005).
Etimología.—Aniso, el prefijo de su nombre, se refiere a los distintos tamaños de los sépalos, nectarios
florales y cotiledones que caracterizan a este nuevo género.

colección concuerda con la fecha referida en la publicación original, por tanto esta última colección es aquí
designada lectótipo. En K, la colección K-220553 tiene dos etiquetas que leen “Capparis pruinosa Gr. Salta”
y “Argentine Comm. Dr. Grisebach, Dec. 1878.” Aunque esa es una colección histórica, sin embargo carece
de mayor información y no se puede determinar si es un duplicado del lectótipo.

Usos.—Los frutos de Anisocapparis speciosa al madurar caen al suelo y la pulpa en el interior se vuelve
muy suave, de color naranja brillante. Éstos se parten a lo largo de las suturas al presionarlos con los dedos,
la pulpa es consumida directamente y la piel es desechada. La consistencia de los frutos es como la de los
mangos (Mangifera indica L.), y tienen un sabor agridulce, entre mango y naranja (I. Gragson 153). Anisocapparis
speciosa es principalmente utilizada para forraje. El ganado come las hojas y frutos de esta especie durante
todo el año, aunque está reportado que las vacas se atoran al intentar tragar el fruto (Vargas et al. 2000).
Fenología.—Floración nocturna (Vogel 483).
Interacciones biológicas. —Las flores de Anisocapparis speciosa son visitadas por por abejas melíferas y
grandes avispas negras (Vargas et al. 2000, Nee 51204). Sus frutos son alimento de mamíferos, como los
venados Mazama | y M. goauzoubira (Stallings 1984; Rivero et al. 2005). Así como en otras especies
de Capparaceae de frutos grandes en América (Iltis et al. 1996), se presume que los frutos de Anisocapparis
speciosa en el pasado sirvieron de alimento para una megafauna extinta en la actualidad.

Monilicarpa se teriza por f brácteas lineares, hasta de 13 mm, localizadas
en y cerca de la base del pedúnculo de las estacas flores con cálices gamosépalos que contienen un
pequeño hipantio, nectarios florales cupulares o disciformes, en cuyos bordes están fusionados los pétalos,
filamentos de los estambres insertos en dos verticilos alternos, granos de polen poseen una ornamentación
estriada-reticulada (Figs. 5, 6, única entre los seis tipos de polen observados entre = EE de hojas
simples en el Neotrópico), y frutos lineares-torulosos a moniliformes, de ápices dos, que
contienen pequeñas semillas elipsoides dispuestas en una hilera, separadas entr sí por las constricciones
de las paredes del fruto.
El nectario floral cupular o disciforme de Monilicarpa está localizado alrededor de un androginóforo
central y fusionado al interior de- y recubriendo a- un pequeño e inconspicuo hipantio. Debido a la pres-
encia de este pequeño panio; el cáliz de Capparis viridiflora Kunth (Humboldt et al. 1821: 92), uno de los
sinónimos aquí citados de liqua, originalmente fue descrito como: “turbinato-urceolatus.”
El nectario floral de Monilicarpa en sus bordes y entre las bases de los pétalos posee cuatro apéndices erec-
tos, dentados o triangulares (Monilicarpa tenuisiliqua) o rudimentarios en forma de inconspicuos lóbulos o
ausentes (M. brasiliana), como se aprecia en la lámina de Capparis brasiliana en Flora Brasiliensis (Eichler en
Martius 1865: 279, tab. 62, hg 1:3, nótese did superior a ia del cáliz. En contraste, Cappa-
ridastrum y Cynophalla, | géneros restantes de las Capparaceae yI p América,
tienen flores con cuatro nectarios, apéndices o escamas nectarias y mox insertos sobre un receptáculo
usualmente plano. Adicionalmente, Monilicarpa se diferencia de Capparidastrum por tener los filamentos de
los estambres insertos en dos verticilos (vs. filamentos de los estambres insertos en varios verticilos), y los

+ redondeados, pocas veces agudos, pulpa! abundante hasta escasa y semillas cocleadas, dispuestas en dos
ó más hileras).
Por sus frutos capsulares lineares-torulosos Monilicarpa se parece a Cynophalla, pero a más de los
caracteres genéricos previamente mencionados, Monilicarpa fácilmente se diferencia de este último género
por poseer flores con cálices 1-seriados (vs. cálices 2- seriados, decusados-imbricados), y vegetativamente
por la ausencia de las glándulas nectarias axilares extraflorales (vs. presentes en Cynophalla) y la diferente
filotaxia.
Algunos géneros distantemente relacionados a Monilicarpa como Atamisquea Miers, Capparicordis Iltis
& Cornejo y Colicodendron Martius, también presentan tazas nectarias o nectarios cupulares, pero éstos
fácilmente se diferencian de Monilicarpa, principalmente por presentar indumento de escamas lepídotas o
tricomas estrellados, diferente tipo de polen y distintos tipos de frutos capsulares o amfisarcos, globosos
hasta oblongos. Frutos lineares-torulosos también están presentes en algunas especies de Quadrella DC.)

Etimología.—El nombre Monilicarpa, alude a los delgados frutos moniliformes a linear-torulosos que
presentan las especies de este nuevo género.
Monilicarpa y Capparidastrum son inermes (Cornejo & Iltis 2005b) y no presentan tallos generalmente
espinosos, como ha sido reportado (Inocencio et al. 2006: 122, 125, ver Capparis sect. Capparidastrum y
Capparis brasiliana).

Los lectótipos de Capparis tenuisiliqua, C. obovatifolia, C. viridiflora y Colicodendron obovatum son aquí des-
ignados debido a que ninguna colección fue referida bajo estas especies en las respectivas publicaciones
originales. En el herbario US, H. García-Barriga 3109 (15933661) no constituye un isótipo de Capparis Garciae,
ésta procede de una localidad distinta, Purificación, y fue colectada en diferente fecha, 7 Jul 1934.
Monilicarpa tenuisiliqua es una especie de hojas deciduas, su follaje se regenera durante la época de
floración (Smith 2100).

Key Wonps: Colicodendron, Capparaceae, Brazil, Ecuador, Perú, Venezuela, endemics
During our studies of the neotropical species of a s.l. (Capparaceae), carried out to produce a generic
realignment of this extremely t became clear that Colicodendron Mart. is a well defined
South American genus of stellate dhrubs mid trees, a by having a l-seriate valvate calyx with a
dentate or lobed nectary-dish or nectary-cup, and thick-walled, indehiscent amphisarcous fruits.
Colicodendron was established by Martius (1839: 25), for two Brazilian species: Colicodendron yco Mart.,
tl ic type, and C. longifolium Mart. (the latter recently placed in Neocalyptrocalyx, as N. longifolium [Mart]
X. mae & H.H. Iltis [2008a]). Subsequently, Seeman (1852: 78) correctly transferred to Colicodendron:
Capparis scabrida Kunth, but also the unrelated Capparis avicennifolia Kunth, and Capparis pulcherrima Jacq.
(the latter as Colicodendron pulchellum Seem., nom. reject.), as well as the quite unrelated glabrous or simple-
haired Capparis subbiloba Kunth (=Cynophalla flexuosa [L.] J. Presl). Two years later, Turczaninow (1854:
321—328) erratically described three species in Colicodendron, all of them synonyms of unrelated species of
Capparis s.l., a contribution that obfuscated any clear concept of that genus.
Colicodendron was treated as a subgenus of Capparis L. s.l. (Eichler 1865: 272), and later as a section of
Capparis (Pax & Hoffmann 1936: 181). In both mentioned infrageneric taxa, the members of Colicodendron
were mixed up in a heterogeneous assemblage with the Mexican Capparis angustifolia Kunth (2 Quadrella
angustifolia [Kunth] H.H. Iltis & X. Cornejo), and the South American C. crotonoides Kunth and C. tweediana
Eichler (both members of Capparicordis H.H. Iltis & X. Cornejo, a recently described stellate neotropical
genus, Iltis & Cornejo 2007). Most recently Hutchinson (1967: 309), in his attempted generic realignment
of Capparis s.l., made seven additional, but all inappropriate combinations to produce a poorly defined
—
Colicodendron.
In this work, a revision of Colicodendron is presented. The genus is validated and amended, its mor-
phological limits are defined, and the relationships with the morphologically closely related genera are
discussed.

Evergreen shrubs or trees, covered by stellate to echinate tric! d hout. Leaves simple, short-petiolate
to sessile, opposite to spirally or castes Inflorescences terminal, "T and/or axilar, a panicle,
raceme or racemose spike, rarely a solitary axillary flower (in Colicodendron yco); floral bracts filiform or
subulate, deciduous. Flowers with calyx 1-seriate, valvate, + cup-shaped, the 4 sepals free, + equal, distinct
and entirely enclosing the corolla in bud, their margins and tips touching each other from early bud until
near anthesis, at the base fused forming a hypantium, coated by a 4-dentate nectary dish or nectary cup or
a 3-lobed nectary cup within. Petals 4, imbricate or torsivus in bud, sessile. Stamens 14 to 60, the filaments
geniculate or spirally arranged in bud, at anthesis exserted, inserted on an expanded flat androgynophore,
anthers basifixed. Fruits amphisarcous or pseudoamphisarcous (in C. scabridum), woody, thick-walled
and multilocular, bearing white- or yellow-embryoned seeds, ca. 1-2 cm, cotyledons ca. 1-1.5 mm wide,
convolute, testa crustaceous.
Due to the stellate pubescence, 1-seriate valvate calyx with the lobes covering the corolla from early
bud until near anthesis, and the presence of a nectary cup or nectary dish, Colicodendron is related to the
recently described neotropical genus Capparicordis H.H. Iltis & X. Cornejo. However, Colicodendron differs
from the latter by having elliptic, lanceolate, oblong to oblanceolate, pinnately nerved leaf blades (vs. cor-
date to reniform or suborbicular and basally subpalmatly-nerved leaf blades); a 4-dentate nectary dish or
3-lobed nectary cup (vs. a nectary cup with four filiform to triangular-filiform appendages); higher number
of stamens, 14 to 60 (vs. 4 to 8); and larger indehiscent thick-walled amphisarcous fruits, with an inflexible
woody pericarp bearing larger seeds, ca. 1-2 cm (vs. smaller dehiscent fruits, with a soft and flexible, thinly
coriaceous pericarp, which splits and falls off at maturity, bearing smaller seeds, ca. 5-7 mm, dispersed by
birds, Cornejo pers. obs., 2002). Colicodendron is also related to the South American genus Calanthea (DC.)
Miers, as was correctly stated by Martius in the original publication (p. 27, cf. with Capparis pulcherrima
Jacq., the type of Calanthea [DC.] Miers). However, Calanthea mainly differs from Colicodendron by the very
distinctive calyx with open aestivation, in which the not valvate linear-ligulate sepals are widely spaced
from each other, exposing a valvate corolla from the very young bud; and by the seeds with barely folded,
very thick cotyledons, 4-7 mm wide (Cornejo & Iltis 2008b).
Colicodendron could be also related to the stellate to peltate, Central American-West Indian genus Qua-
drella (DC) J. Presl. However, Colicodendron differs from the latter by having flowers with a hypanthium coated
by a nectary dish or nectary cup (vs. flowers without hypanthium, but with a flat ptacle and four scales
inserted on it in Quadrella); and indehiscent, ellipsoid to globose thick-walled woody amphisarcous fruits
with larger seeds (vs. capsular, dehiscent, linear or oblong and few times to ovoid, with seeds distinctively
smaller, usually arranged in a single row in Quadrella).
Colicodendron was previously known by two widely disjunct endemic species: Colicodendron yco trom
eastern Brazil, and C. scabridum (Kunth) Seem., restricted to the dry forests of western Ecuador and adjacent
Peru. In this work, two additional South American endemic species, both with whorled subsessile leaves
and beautiful inflorescences are added to this genus.

subsessile, with blades narrowly oblanceolate to narrowly elliptic, 13—40 x 3-7(-10) cm, stiff, coriaceous
(alive), chartaceous (dry), attenuate and revolute at the base, acute and apiculate to sometimes shortly
rostrate at the apex, shiny green (alive) with an impressed to often sulcate midvein, nerved and glabrous
above, paler green (alive) and with a strongly prominent glabrous or echinate-stellate midvein beneath,
margin inconspicuosly thickened, with 15 to 25 major upward-arching lateral nerves on each side of the
midvein. Inflorescences terminal and subterminal racemes, sometimes cauliflorous in older wood, densely
stellate-echinate; axis short, 1-5 cm, stout, bearing to 25 flowers at the same time. Floral bracts linear, 3—7
mm, deciduous, densely echinate-stellate. Pedicels 1.8—4 cm, articulate to the axis. Sepals oblong-elliptic or
ellipsoid to lanceolate, 12-22 x 6-8 mm, abaxially keeled, mainly toward the base, + acute at apex, yellow
(alive), rusty brown (when dry), stellate-echinate abaxially; hypanthium 4—6 mm deep, coated by a subtet-
ragonal 4-dentate nectary dish within, nectary appendages broadly deltoid to semiorbicular, 1.5 x 2.5-4
mm, glandular, stellate. Petals torsivae in bud, apparently inserted at the SE e the nectary cup, oblong to
obovate-oblong, 20-28 x 7-12 mm, widely obtuse to rounded at apex, longi lly nerved, sulfur yellow
and erect at anthesis (Mori, pers. com.), dull rusty-brown (when dry), stellate on both sides. Stamens 30 to
42, filaments 2-3 cm, geniculate in bud, glabrous, inserted on a white-stellate-tomentose expanded torus-
like androgynophore, anthers ca. 2 mm, white (alive). Gynophore 1.6-2 cm, glabrous; ovary oblong, 5-6
x 2-3 mm, longitudinally sulcate, glabrous; stigma sessile, capitate. Infructescences with gynophores ca.
2-2.5 x 0.3-0.5 cm, pedicels ca. 3-3.5 cm. Amphisarcous oblong-ellipsoid, 7-12 x 2-4 cm, subpendulous;
fruit wall 3—7 mm thick, mature seeds 1.3-1.7 mm in diam.
Colicodendrum bahianum is somewhat related to the equally yellow-flowered C. yco, is allopatric in the
dry Caatinga to the north (Fig. 7). However, the more mesophytic C. bahianum can be easily distinguished
by dense whorls of subsessile leaves, arranged toward the end of the terminal branches (Fig. 1A, vs. sub-
opposite and pedicellate leaves, more spaced out along the branches). The inflorescences of Colicodendrum
bahianum are short dense racemes (vs. larger and longer, paniculate inflorescences, or rarely solitary axillary
flowers in C. yco), bearing flowers with erect (vs. reflexed) sepals at anthesis, higher number of stamens (30
to 42 vs. 14 to 20 in C. yco), smaller anthers (ca. 2 mm vs. 4 mm), shorter glabrous gynophores (1.6-2 cm
vs. 3.5—5 cm, pubescent) and glabrous (vs. DUE ovaries.
Due to the whorled subsessile leaves, Coli
to the herein also described Colicodendron valerabellum H.H. Iltis, T. Ruiz & C 3x Sura (for differences see
comment under the latter species).
Phenology.—Collected in flower in February, July, August, November and January, and fruit in August.
The sulfur yellow flowers are visited by hermit hummingbirds (Webster 25010).
Cytology.—Unknown.
Distribution —Eastern Brazil, restricted to the southern extension of the moist or wet evergreen Atlantic
rain forests (ca. 2000 mm) into southeastern Bahia State (Fig. 7).
Conservation concern.—Habitat is under intense human pressure from both agriculture and wood har-
vesting, especially for so decorative species Colicodendrum bahianum (Scott Mori, per. comm., Sep 1979; “It
was one of the most beautiful species that I’ve ever seen”). Images of this potential ornamental species are
available at the New York Botanical Garden Web site (NYBG, 2003).

Nomenclatural note. —The herein selected lectotype of Cap; brida housed at P, has a label with a correct
origin of the specimen, *in America equatoriale," and the number *19? added. The B isolectotype of Cap-
paris scabrida consist of a branch with a terminal inflorescence, with the two leaves, one inflorescence, and
floral pieces detached and remounted. That isolectotype, originally only identified as Capparis, was named
Capparis speciosa (a Willdenow's nomen nudum, non Capparis speciosa Griseb. [1879], = Anisocapparis speciosa
[Griseb.] X. Cornejo & H.H. Iltis), as reads the label which is at the upper left corner of the photo 9478, now
in a separate sheet (B-W 10055 -00 O). That label has the following handwritten information: "Polyandria
Monoginia Capparis speciosa racemi(?) terminali, foliis ovato-lanceolatis obtusis mucronatis supra nitidis
glabris subtus tomentosis foliola elliptica. Habitat in America meridionali." The discussed isolectotype later
was correctly identified by Eichler himself, in a handwritten label of determination, which reads: “Capparis
(Colicodedron) scabrida H.B.K.
Multi-branched shrubs to trees, to 10 m and 25 cm dbh, erect to low and widely spreading; the stem

cm, pendulous, + umbonate at the apex, densely stellate, when mature exhibiting 8 longitudinal + sulcate
(dried) lines (usually 4 major, indicating the valves); fruit wall fibrous, 6-10 mm thick, pulp bright orange
at maturity, insipid; seeds 15 to 60, subspherical-reniform, often strongly beveled, ca. 1-2 x 1-1.5 cm, sur-
rounded by a densely orange testa infiltrated by many hairs from the crustaceous reddish-brown testa;
embryo yellow.
The amphisarcum is a simple, indehiscent fruit, provided with a thick, woody to subwoody fruit-wall,
which retains the shape upon removal of sarcocarp, and never splits in valves after maturity (Spjut 1994:
23. 37). In Colicodendron scabridum, the fruits at maturity fall on the ground to eventually decompose and
release the seeds, leaving usually four thickly-subwoody, elliptical, abaxially convex, unattached, persistent
valves. That fruit type of Colicodendron scabridum, which doesn't fit in any of the fruit types known (Spjut
1994), is herein proposed as Pseudoamphisarcum (pseudo + amphisarcum) X. Cornejo (mod. nov, which
means a false amphisarcum.
Local names.—ECUADOR: Sapote (Spanish, Little 6725), sapote de campo (Spanish, Van den Eynden et
al. 1999: 42), sapote de perro (Spanish, Cornejo & Bonifaz 7583), sapote gomoso (Spanish, Steyermark 54842);
Zapotillo (Spanish, Brandbyge 42789); Zapote de perro (Spanish, Acosta-Solis 8521, Mille 1940, Madsen 64103).
PERU: Sapote (Spanish, Díaz & Baldeón 2374), sapote de perro (Spanish, Woytkowski 5672). Zapote (Spanish,
Vargas 42), Zapotillo (Spanish, Simpson & Schunke 567).
The bright orange color of the mature fruit pulp of Colicodendron scabridum strongly resembles the color
of the pulp of a locally (in Ecuador) well known edible fruit called “Sapote” (Quararibea cordata |Bonpl.]
Vischer, Bombacaceae). This is the origin for the several similar and derived local names of Colicodendron
scabridum.
“Sapote de perro,” one of the local names, refers to Pseudalopex sechurae Thomas. This is an endemic
canid locally known as “Perro de monte" (Spanish) or *Sechura fox” (English), that has a distributional pat-
tern similar to that of Colicodendron scabridum in the dry coastal areas of Ecuador and Peru. When the food
is really scarce, the Pseudalopex sechurae facultatively eats the fruits of Colicodendron scabridum (Bruning
1985; Cornejo 2005).
Zapotillo (Spanish), a town located in a dry forest at the Province of Loja in Southwestern Ecuador,
owes its name to the local name of the locally well known Colicodendron scabridum.
Phenology.—Flowering mostly between February to October, fruiting mostly September to December.
A single tree 4-6 m high, produces 20 to 60 flowers at anthesis per night. Within the nectary cup, three
droplets of nectar start to be produced at 19:00 h., each droplet from below of each nectary lobe. By 19:30 h,
the nectary cup is full of nectar. But by the next morning at 6:00 h, the flowers don't have nectar anymore,
perhaps due to the intense bat activity during the night. The nectar is secreted during one night per flower
only. The flowers live one night only and don't produce any scent (Cornejo field obs. in Bahía de Caráquez,
Ecuador, July 2004).
Cytology.—n = 8 [!Pazy, icu: Manabi: Iltis Ena e ee "E Iltis unpublished ms).
Distribution.—Colicodend nent of dry to very dry or xerophytic
areas of western Ecuador and Perú, where is a dune former. This species ranges from sea level in Ecuador
from the Province of Manabí, to ca. 2500 m in the mountains of the Province Loja, and in Perú south to
Dept. Ancash (Fig. 7).
Ecological interactions and field observations.—The flowers of Colicodendron scabridum are visited by the
common domestic honey bee, Apis mellifera L. Dozens of buzzing bees can be heard from under a tree when
the nocturnal flowers are just about to open. The honey bee's activity peaks in and around the flowers of
Colicodendron scabridum is between 18:30 to 19:30 h. The domestic bees re-start re-visiting the flowers the
next morning, as well between 6:00 to 8:00 h. Nocturnal, presumably pollen predator bees such as Halictidae
(Megalopta?), also visit the flowers at 19:00 h. While both species of bees touch the anthers and the ovaries,
it seems however that the true pollinators are bats. From 20:00 to 5:50 h, many small bats frequent the
flowers of Colicodendron scabridum, which are exposed on long peduncles high above the foliage. The bats
beat their wings hovering in the air while licking the nectar from each flower during less than one second,

as hummingbirds are apt to do. The bats do not hold themselves from the flowers as happens to the African
Bignoniaceae, Kigelia africana [Lam.] Benth. (seen in Bahía de Caráquez, Ecuador, the same locality where
Colicodendron scabridum was studied by the senior author). When leaving the flower, the bat shakes the inflo-
rescence, presumably helping pollination. It is interesting to note that only the individuals of Colicodendron
scabridum growing in total darkness are visited by bats. These conspicuously have a higher fruit productiv-
ity per tree than the remaining individuals located around the nocturnal lights along the roadsides in the
same locality. Additionally, the flowers of Colicodendron scabridum are also visited by Amazilia amazilia, a
hummingbird who visits the old (previous night's) flowers between 7:00 to 8:00 h, and the new flowers just
about to open at ca. 18:00 h. Finally, the flowers of Colicodendron scabridum are ly visited by wasps,
coleoptera and several species of ants (Cornejo field obs. in Bahía de Caráquez, Ecuador, July 2004).
Uses.—The fruits have been reported as edible for humans and as medicinal against colds and coughs.
They are commonly eaten by cattle and donkeys (C. Cerón et al. 22424, Van den Eynden et al. 1999: 42,
Cornejo field obs.), while the wood is used for fuel and to make handicrafts (Cornejo & Bonifaz 7583, Van
den Eynden et al. 1999: 42). Finally, a "glue" for paper can be obtained from the cut, gum-oozing ends of
the stems (Cerón 11876).
Conservation biology.—A characteristic common species in the dry landscape, it does not appear to be
in danger of extinction.

Colicodendron valerabellum differs widely from C. yco by the characters written in the Latin diagnosis.
Due to the leaves arrangement in crowded whorls at the end of the terminal branches (Fig. 3A, 5A) and
unbranched inflorescences (Fig. 3C), Colicodendron valerabellum seems more closely related to the Brazilian
C. bahianum (Fig. 1A). However, Colicodendron valerabellum differs from the latter by having spicate inflo-
rescences with a larger central axis, 10—30 cm (Fig. 3C, vs. racemose, with shorter central axis, 1—5 cm,
Fig. LA), bearing subsessil (vs. 1.8-4 cm, pedicellate) flowers, longer gynophore, 8-9 cm (vs. 1.6-2 cm),
subglobose (vs. oblong) ovaries; subglobose fruits (Fig. 6H, vs. oblong-ellipsoid, Fig. 2) and by its localized
distribution, in northwestern Venezuela (vs. eastern Brazil, Fig. 7).
Phenology.— Colicodendron valerabellum apparently begins to flower in November, not long after the end
of the rainy season, and continues to bloom into April or May (or *does it flower twice a year, once in May
and again in November?”), with older hermaphrodite flowers beginning fruit enlargement with the com-

istem that continues to grow from the center of the upper-most leaf whorl. It is, TIENE er, a structure most
lly sessile or subsessile
unusual in many respects, not the least of which is the fact that its fl
on the peduncle axis, with the pedicels very short and thick, so that this structure, rather than a raceme,
could better be called a racemose spike. The remaining species of Colicodendron and even of the neotropical
Capparaceae s.s. have flowers borne on well developed pedicels. In this comparatively specialized species,
this loss of pedicel is linked to a basically primitive, racemose inflorescence, while its three relatives, C.
bahianum, C. yco and C. scabridum, have pedicellate flowers in racemes or panicles, presumably the derived
condition. Correlated with this loss of pedicel in C. valerabellum may be the great length, thickness and
stiffness of the peduncle, truly spike-like in the non-botanical meaning of the word, ultimately becoming
a full centimeter thick and to 40 cm long, which eventually decompose. Around the stubby remains of
the old inflorescence in the center of the leaf whorl, several axillary buds, densely covered with subulate
bracts, may be initiated. These in turn may produce 1 to 3 replacement axes, essentially by continuing the
unbranched growth upward and the production of another flowering spike, or else lead to the branching
of the stem into 2 or 3 axillary branches.
Although variable in particulars among individuals, the paran terminal Bp bear flowers in the
following sequence: the lowest floral buds soon abort, leaving only pedice Isca duncle (these buds
are usually naked, but in some inflorescences subtended by up to 20 or so small leaves rapidly decreasing in
size upward and spaced over a distance of some 10 cm). Moving upward, the next 3 to 6 flower buds, well
spaced and the first to burst into bloom, develop into fully functioning hermaphrodites, in which the many
stamens are exceeded for about 1 cm by a gynophore bearing its well-developed ovary. Finally, towering above
the circle of hermaphrodite flowers, and densely aggregated at first into a narrowly conical inflorescence,
are some 20 to 100 staminate flower buds, with only 2-3(-5) of these blooming at one time, beginning at
base and continuing upward. The whole inflorescence thus has a long-extended flowering period lasting
perhaps a month, and in the process gradually elongating the peduncle to its maximum length. Once the
staminate flowers finish blooming, they soon wilt and fall off, leaving only the symmetrically placed, oval
pedicel scars on the peduncle.
If the hermaphrodite flowers at the base of the spike become fertilized and commence fruit develop-
ment, the peduncle above them eventually dries up and tually decomposes. But if these hermaphrodite
flowers are not fertilized, not only do they fall off, but also the peduncle then often retains its stiff, thick
structure to eventually produce a new set of hermaphrodite flowers near its tip some 30 cm or more up from
its base. This double insurance that seeds will eventually be produced may be the key to understanding the
function of so massive a structure.
Clues to the enigmatic reproductive morphology of Colicodendron valerabellum must lie in its pollina-
tion agents. Of the eight main attributes of the bat pollination syndrome (Chiropterophily) cited by various
authors (Pijl 1961: 51; Faegri € Pijl 1966: 114; Vogel 1958: 492), the following six would seem to apply to
Colicodendron valerabellum: 1) Nocturnal anthesis, the flowers lasting only one night. 2) Flowers and inflo-
rescences strong enough to carry the weight of a bat (subsessile, often many flowers on the strong pedicels,
thick calyx, powerful peduncle, i.e., racemose spike axis). 3) Honey abundant, mucilaginous, accessible
(to sphingid moths as well). 4) Flower (corolla) yellowish or creamy. 5) Pollen abundant. 6) Inflorescence
exposed high above the foliage.
Biological interactions. According to a local informant, the fruits of Colicodendron valerabellum are eaten
by deer (Iltis et al. 30547, WIS).
Why the big fruits of Colicodendron valerabellum should be borne high above the leaves is a curiosity,
when in its close relatives, as in most Capparaceae, heavy fruits hang down. Or were the fruits/seeds of
Colicodendron valerabellum dispersed internally by the now extinct megafauna as the giant Gomphotheres
(Janzen & Martin 1982), as suggested for Neocalyptrocalyx muco (H.H. Iltis, Cumaná, Delgado & Aymard)
X. Cornejo & H.H. Iltis, another giant-fruited Capparaceae of northern Venezuela and Colombia! (Iltis et
al. 1996: 379, see Capparis muco).
Cornejo and Iltis, Revision of Colicodendron 89
Cytology.—Unknown.
Distribution. — Colicodendron valerabellum is known only from one limited metapopulation of several,
scattered minute populations, with perhaps a total of 20 to 40 plants, growing in extremely disturbed, open
tropical deciduous forest remnants and thickets on top of 10—20 m high, steep and badly eroding road cuts
and local trash dumps scattered for 3 to 7 km north of Valera (654 m) along and immediately above the old
highway to Motatán (ca. 500 m), in northwest Venezuela (Fig. 7). Growing in seasonally dry, semi-deciduous
to deciduous open forest or woodlands of medium-sized trees, the *bosques higrófilos y mesófilos de las
sierras en la región Andina" (Hueck 1960), or in degraded secondary thorn thickets (matorral).
Conservation biology.— Colicodendron valerabellum appears to be close to extinction, but with all known
populations restricted to the edge of the old yet easily accessible Valera-Motatán highway, and the rest of the
landscape barely explored, the possibility exists that the extensive woodlands covering the hills above the
road may wel! hold more extensive stands. In fact, this is also suggested by the presence of a common name,
"fruto de venado” (fruit of the deer), since rare species are generally not honored with common names.
The few plants known to exist are certainly in trouble reproductively: except for the inflorescence with
two young fruits photographed by Bunting in 1983, the two somewhat older fruits collected by Ruiz-Zapata
in 1997, and the five hermaphrodite flowers with developing ovaries at the tip of an inflorescence collected
by Ruiz-Zapata in 1998, no other fruits, young or old, have ever been located despite assiduous searching.
Perhaps, like many a taxon at the end of its evolutionary career, C. valerabellum is not reproducing well.
Negative human influences such as firewood gathering, land clearing, and grazing by cattle as well as the
unknown but negative impact of pesticide spraying can also not be discounted.
What is clear, in any case, is that the limited fruit production in all the ined populations (by H.H.
Iltis) may be due to one or more of the following: 1) The often densely crowded stems may be clones, and,
if self-incompatible, cannot form fruit unless cross-pollinated; 2) land clearing may have reduced genetic
diversity to the point of no return; 3) the population is inbred, reducing seed production; 4) populations
of the pollinating agents (sphingid moths, bats, or hummingbirds) have been much reduced by pesticide
application to the local maize fields; 5) the species is adapted to an undisturbed summergreen open wood-
land periodically cleared by fire, and now these relictual stands have to compete with weeds in a liana-rich,
secondary community induced by human disturbance; 6) A remarkable number of Capparoids in the region,
have extra-large, more or less woody, indehiscent fruits that, as one of us suggested (Iltis et al. 1996) may
have had Gomphotheres, now extinct, as their dispersal agent (Janzen & Martin 1982).

INTRODUCTION
f lass Dep 1] fA A 7 E WE | ^
About fifty sp subtribe Got inae (Apocynaceae: Ásclepiadoideae) occur ronthe islands comprised
by the Greater and Lesser Antilles, the Bahamas E and E and Aruba and the Netherland An-
tilles. Evidence from the chloroplast (Rapini et al. 2003; Liede-Schumann et al. 2005; Rapini et al. 2006;
Krings et al. 2008) and nuclear genomes (Krings et al. 2008) supports the monophyly of the subtribe. Genera
referred to the subtribe with M centanon o in dees GE ees Phera DC., Gonolobus Michx., Matelea
Aubl. (incl. Ibatia Decne., Jacaima Rendle, P ] EECH Decne.), Macroscepis
Kunth, and Metalepis Griseb. (Fontella & Schwarz 1981a: Rinze 1995; Died: 1997; Morillo 1997; Rapini et
al. 2003; Liede-Schumann et al. 2005; Rapini et al. 2006). Subtribal position has been most controversial
kers have also placed within a broad Cynanchum L. (Woodson 1941; Spellman
for Metalepis, which some
1975; Sundell 1981). Recent evidence places it basal to a well-supported Metastelmatinae-Oxypetalinae-
Gonolobinae clade (Liede & Kunze 2002; Liede-Schumann et al. 2005). The last regional treatment of
Gonolobinae is now over 100 years old (Schlechter 1899) and a number of new species have recently been
described by various workers, including Britton, Krings, Liogier, Proctor, Spellman, Urban, and Woodson
(see Krings 2005b, 2006, 2007). Most members of the subtribe have never been monographed (Rapini et
al. 2003) and the circumscription of most genera remains poorly defined. The Gonolobus-Matelea complex
in particular is in desperate need of taxonomic revision. However, the size of the complex (ca. 200-350
sppJ requires an approach focusing on smaller, more tractable subgroups. Considering the support for a
monophyletic Gonolol s. based on recent evidence from chloroplast (trnL-F, rps16) and nuclear (LEAFY)
data (Krings et al. 2008), recent t ic changes in West Indian taxa (Krings 2005a—d), and that several
species have been published from the area since the last comprehensive treatment over a hundred years ago
(Schlechter 1899; Krings 2006, 2007), a revision of the genus in the West Indies seemed appropriate. This
revision treats all ten West Indian Gonolobinae species referable to Gonolobus s.s. (i.e., characterized by the
presence of laminar, dorsal anther appendages, winged follicles, and a synapomorphic guanine; Krings et
al. 2008). In addition, two new combinations are made in Matelea: M. dictyopetala and M. pubescens (see
Doubtful and excluded names).

METHODS
This treatment is based on critical study of ca. 250 specimens of the fifty some known species in West
Indian Gonolobinae, obtained in part through: (1) loan requests from ninety herbaria—of which sixty-hve
responded with either loans, digital images, or negative search results (see Acknowledgements), (2) visits
to BM, BSC, DUKE, HAC, HAJB, IJ, K, UCWI, UPRRP, US, and P, and (3) forty-eight days of field work by
the author in the Bahamas (Long Island), Cuba, Dominica, Jamaica, Puerto Rico, St. Lucia, and St. Vincent.
The treatment is also informed by analyses of sequences of portions of the chloroplast (trnL-F, rps16) and
nuclear genomes (LEAFY) of selected accessions (see Krings et al. 2008). The species concept employed is
an amalgam of the Phylogenetic Species Concept (PSC) of Nixon and Mee (1990) and the Evolutionary
Species Concept (ESC) as Hoc by Wiley (1978), namely that: a species is a lineage of ancestral-descendent
populations, which tained their identity from other seh] lineages, and sieh are diagnosable by a
unique combination of character states in Ge individuals. Although the PSC has been critiqued as
a non-historical concept—and tl tially failing to identify instances of phenotypic homoplasy (Baum
& Donoghue P een has not been accepted universally (Luckow 1995). The concept has been
useful both as t efinition and operational delimitation criterion. However, as the application of the
PSC, and its ONE EE EE EEN ge (PAA; Davis & Nixon 1992), requires study
of populations, its application is limite uniquely from a population, or worse, from
a single collection a Bis e also In the absence of ODDS multi- porn accessions ini extant
and historical species, the po EE E here is to rely on obse I
with the general phy! due to a variety of biological BE

L L
underlying tl hologi ide al integrity of species (McDade 1995). As a result, character states
of each lone papules a I tative were assum ed fixed a together used to form a population profile
for PAA. Specimens representing each distinct aggregated population profile were considered to belong to
distinct species, even if represented by only single collections, if they exhibited unique, qualitative morpho-
logical character states, unknown from other population profiles. As with any hypothesis, concepts of these
pee are open to modification and reinterpretation in light of SCH new collections.
tion status oft d | lly evaluated by applying the criteria articulated
in version 3.1 of the International Union for on of Nature and Natural Resources (IUCN) Red
List Categories and Criteria (IUCN 2001) and version 6.1 of the NatureServe Conservation Status Ranks
(NatureServe 2006).
RESULTS
Ten species of Gonolobus are recognized from the West Indies, here defined to include the Bahamas, the
Greater Antilles, and the Lesser Antilles (excl. Aruba, Bonaire, Curacao, Trinidad, and Tobago; Fig. 1). All
ten species are endemic to the region. Descriptions of the species are provided following a discussion of
morphology and keys to the species. Corona morphological terminology follows Liede and Kunze (1993)
and Kunze (1995): Ca = faucal annulus (corolline corolla); Cd = dorsal anther appendage; Ci = interstaminal
gynostegial corona; C(is) = fused staminal and interstaminal gynostegial corona; Cs = staminal gynostegial
corona. Species are arranged alphabetically. IUCN criteria justifying an assigned conservation category are
listed following each category. Following Franz et al. (accepted), taxon concept mapping is provided to facili-
tate databasing. The operators «, =, and > are used to indicate whether a given taxon concept is respectively
narrower than, equal to, or broader than a previously published concept. The symbol + is used to indicate
the misapplication of a name to a concept. Herbarium abbreviations follow Index Herbariorum (Holmgren
& Holmgren 1998-present). Book abbreviations follow TL-2 (Stafleu & Cowan 1976-1988) and journal
abbreviations B-P-H (Lawrence et al. 1968) and B-P-H/S (Bridson & Smith 1991). Author abbreviations
follow Brummitt and Powell (1992).

TAXONOMIC HISTORY
The genus Gonolobus was erected by Michaux in 1803 based on a taxon from t] theastern United States—
Gonolobus suberosus (L.) R.Br. Reveal and Barrie (1992) reviewed the complicated nomenclatural history of
the type species and Krings and Xiang (2004, 2005) its t y. About 318 names have been published in
Gonolobus. Estimates of species numbers in the genus vary from 100 to 150 (Rosatti 1989; Mabberley 1997:
Stevens 2001). The degree of variation is largely the result of still poorly known tropical taxa and differ-
ences regarding generic limits. Woodson (1941) considered that the genus Gonolobus should contain plants
characterized by only none: oo EE EE dorsal anther Ap pensas. M" smooth, angled or
A 1
] 1 by glandular ] trichomes,
ni
winged follicles,
anthers lacking laminar dorsal appendages, wi muricate follicles. Unconvinced that laminar dorsal anther
appendages should serve as a generic character and citing examples of smooth [but not angled or winged]
fruits in Matelea, Shinners (1950) argued against Woodson's generic concept and later included twelve of
Woodson's (1941) Gonolobus combinations in Matelea (Shinners 1950, 1964). Drapalik (1969) essentially
followed Shinners by maintaining the type of Gonolobus Oe. G. suberosus, syn. G. gonocarpos (Walter) L.M.
Perry) in Matelea, although noting its morphological distinctness vis-a-vis other subtribal members in the
southeastern United States. Taking a broader geographical persp f logy, Rosatti (1989)
argued for renewed circumscription of Gonolobus based on the presence y. laminar deal anther append-
ages. Most recently the concept of Gonolobus as characterized by short, capitate-glandular, short acicular,
and long acicular trichomes, laminar dorsal anther appendages (typically), and smooth, winged follicles
has been used by Stevens (2001). However, glandular hairs, although thought characteristic of Matelea by
Woodson (1941), also appear without circumscriptional value in the Gonolobus-Matelea question, being pres-
ent in both the type of Gonolobus and numerous species lacking dorsal anther appendages (Rosatti 1989).
Nonetheless, the monophyly of Gonolobus, whether narrowly or broadly circumscribed, was supported in
a recent analysis of chloroplast and nuclear data (Krings et al. 2008). Although parsimony is equivocal on
98 | loft tanical Insti Texas 2(
whether laminar dorsal anther appendages evolved once in the most recent common ancestor of Gonolobus
s.l., or once in Gonolobus s.s. and once in the Fimbristemma Turcz. group within Gonolobus s.l. (Fig. 2), the
character remains restricted to the Gonolobus s.l. clade within Gonolobinae. Interestingly, winged follicles
appear to have arisen twice independently and can be considered sy napomorphic for both Gonolobus s.l.
(Krings et al. 2008), as well as for a mostly West Indian ocellate-petaled complex that likely includes Matelea
acuminata (Griseb.) Woodson, M. bayatensis (Urb.) Woodson, M. correllii Spellman, M. costata (Urb.) Morillo,
M. nipensis (Urb) Woodson, M. oblongata (Griseb.) Woodson, M. pusilliflora L.O. Williams, M. rhamnifolia
(Griseb.) Krings, and M. tigrina (Griseb.) Woodson. None of these latter taxa exhibit laminar dorsal anther
appendages. This putative complex did not evolve within the Gonolobus s. L clade and may deserve indepen-
dent generic recognition. Members of the complex tend to share morphological characters apparently rare
in Gonolobus s.l., such as reticulate, ocellate corollas.
A no E Gonolobus s.l. can be characterized by the pium e two synapomorphic indels in
LEAFY, as well as winged follicles (Krings et al. 2008). A p! bus s.s. can be characterized by
a synapomorphic transversion in ml. F (thymine to guanine) not sated by any of 154 other Asclepiadoideae
species sampled across Secamoneae, Ceropegieae, Marsdenieae, and Asclepiadeae. The former circumscrip-
tion (i.e., Gonolobus s.1.) essentially agrees with that of Woodson (1941), Rosatti (1989), and Stevens (2001),
and stands in contrast to that of Shinners (1950) and Drapalik (1969). To remain monophyletic however,
Gonolobus s.l. must include the Matelea denticulata (Vahl) Fontella & E.A. Schwarz complex. Considering
the morphological and molecular distinctions between the three lineages in the Gonolobus s.l. clade (Fig. 2),
recognition of three separate genera currently seems preferable to me.
MORPHOLOGY
A discussion of the morphology of species of Gonolobus s.s. (hereafter simply Gonolobus, unless otherwise
specified) is provided below. The discussion concentrates on West Indian Gonolobus species, but when pos-
sible provides a broader context of variation within West Indian Gonolobinae.
Growth form.—Species of West Indian Gonolobus are twining vines, as are all currently known members
of West Indian Gonolobinae (Fig. 3A). Older stems may become somewhat woody, but no collection or live
plant has been seen by the author that approached 1 cm or greater in diameter. Individuals may climb as
high as a few meters in gaps and openings.
Latex.—Latex is known for the following species: Gonolobus iyanolensis Krings, G. jamaicensis Rendle,
G. stapelioides Desv. ex Ham., G. stellatus Griseb., G. stephanotrichus Griseb., G. waitukubuliensis Krings,
and G. youroumaynensis Krings. It has been primarily described as either milky or white, observations
confirmed by the author in the field for G. iyanolensis, G. EE G. E MAN G. Beer G.
tar +
waitukubuliensis, and G. youroumaynensis. Latex was described by collectors a
Puerto Rican collection of a young sterile vine referred to G. las (Acevedo- Rodrigues e» nos
7785, US!). Published studies of latex chemistry in Gonolobinae are unknown to the author, although such
inquiry would likely yield interesting results based on studies of other members of Asclepiadoideae (see
Uses). Latex chemistry has been applied to solving taxonomic problems in Cynanchinae (Liede et al. 1993;
Liede & Kunze 2002).
Pubescence.—Most | f subtribe Gonolobinae, exhibit at least two distinct t
frequently more. West Indian species of Gonolobus exhibit Du types: (1) multi-cellular, sharp, eglandular,
(2) uni-cellular, sharp, eglandular, (3) uni-cellular, glandular-capitate, and (4) papillate (Fig. 3B). Papillae
appear to be restricted to the adaxial surface of the corolla lobes—typically borne only on the right side of
the lobes. The remaining trichome types may be found anywhere else on the stem, leaves, inflorescences, or
flowers, usually in combination. Multi-cellular, um aes Home found on stems are primarily

West Indian Gonolobus are not borne in two distinct lines.

Leaves.—In general, species of Gonolobus exhibit simple, opposite, membranous, cordate leaves, al-
though a few taxa, such as the Jamaican G. stellatus, G. jamaicensis, and G. stapelioides, exhibit truncate to
cuneate leaf bases (Fig. 3A & C). The leaves of G. jamaicensis and G. stapelioides tend to be coriaceous. Leaf
apices vary from acute to acuminate. Leaf size and shape may be influenced by position on the stem (e .g.,
basal vs. terminal) and habitat (e.g., ge vs. Pes interior; sun vs. shade) (Krings, pers. obs.).
Laminar colleters.—1n West In G } ies, as in all West Indian Gonolobinae, two or more
colleters are borne on the adaxial midrib near the eegen of the leaf base and the petiole apex (Fig. 3D).
Colleters vary from deltoid to lanceoloid.
Stipular colleters.—In West Indian Gonolobus species, a single colleter is borne on each side of the
petiole at its extreme base (Fig. 3E). Colleters vary from deltoid to lanceoloid. Inter-petiolar (borne along
a ridge or line between two opposing petioles at a node) colleters are rare and infra-petiolar (borne within
the width of a petiole at its base) are apparently absent. Stipular colleters in other West Indian Gonolobinae
vary in position, but frequently appear to be associated with the stem rather than the petiole.
Inflorescences.—Inflorescences of most West Indian Gonolobinae species, including all Gonolobus
species in the area, are extra-axillary and racemose (umbelliform inflorescences appear to be restricted
to Haitian Matelea crispiflora (Urb.) Jiménez). Inflorescences can be borne at nodes with immature leaves

as short as 13 cm long. The inflorescence is indeterminate and a series of flowers are produced on lateral
pedicels from a single axis, the oldest at the base and the youngest at the apex (Fig. 3F). The axis is frequently
significantly contracted and may not measure more than 1 cm in some species. In West Indian Gonolobus,
bracts are frequently borne at pedicel bases, although they tend to be small and caducous in most species.
For additional a review of inflorescence structure in other members of Asclepiadoideae, see Liede and We-
berling (1995).
Based on specimens of West Indian Gonolobus seen in the course of the present study, one to three
flowers may be open at a time. No phenological studies in West Indian Gonolobus have been undertaken and
the life span of individual flowers remains unknown. Based on prior studies in Gonolobinae (see Lipow &
Wyatt 1998; Krings 1999) and informal observation, it is unlikely that individual flowers last much longer
than a week. In Gonolobus suberosus of the southeastern United States, individual flowers were open (2-)
4.61 (-10) days (N = 175; s.d. = 1.53) and inflorescences had open flowers for (2 8.96 (-23) days (N = 57;
s.d. = 4.63) (Lipow & Wyatt 1998).
Aestivation. Sane EEN of West nd Mid. species are imbricate and dextrorse in bud (Fig.
3G). Imbricat t also i of West Indian Gonolobinae, but not all other genera
exhibit dextrorse buds.
Calyces.— Calyces of Gonolobus species consist of five, green sepals (Fig. 3H). Apices are g lly nar-
rowly obtuse to rounded. Adaxial surfaces are uniformly glabrous. Abaxially surfaces vary from pubescent
to glabrous. Frequently, the distal pedicel pubescence (when present) creeps onto the calyx base.
Calycine colleters.—West Indian Gonolobus species, as most members of West Indian Gonolobi
bear 1-2 colleters in each sepal sinus us 3D. The colleters are DT to cds
Corollas.— Corollas inr Indian Gonolobinae, including all G I in the area, are 5-lobed
(Fig. 3)). Corollas are late to campanulate at the base with lobes spreading to reflexed.
The corolla lobes of SR DCH are EM An exception is Jamaican G. stapelioides, which exhibits wavy
and recurved EE EES Corolla lobes of Gonolobus in the area nd overlap at the base and frequently
bear a minute gl g in the sinus. Adaxial corolla coloration of West Indian Gonolobus species
varies from anio green (most taxa) to burgundy tinged (G. stephanotrichus) to maroon (G. jamaicensis).
Pubescence of the adaxial surfaces, when present, is limited to the faucal annulus and surrounding corolla
lobe bases, and the right side of the corolla lobes.
Corolline coronas: Faucal annuli.—Faucal un sensu Liede and Kunze (1993), non sensu
Woodson and Moore 1938 (see Kunze 1990, 1995) —are nular thickenin gs of the tubular por-
tion of the corolla (Fig. 3Ki-iii, L). Endress and Bruyns (2000) considered the Ca and Cc (corolline corona)
of Liede and Kunze (1993) homologous, although Fishbein (2001) and Kunze (2005) explicitly rejected this
hypothesis. Kunze (2005) noted that early ontogenetic EES of even taxa such as G. lasiostemma (Hemsl.)
Woodson, which exhibits a Ca of five large fleshy lobes int inally (similar to Jamaican G. stapelioides),
show a closed annular meristem at the initial stage. Faucal annuli (Ca) are distinctive in West Indian
SCH species and generally much more developed in members of this genus than in other West Indian
Kunze (1995) found faucal annuli present in continental Gonolobus spp., as well as Matelea
lanata (Zucc.) Woodson, and Matelea dictyantha Woodson, and absent in Matelea tinensis (T. Mey.) Pon-
tiroli and Fischeria spp. (all Gonolobinae). He also noted that outside Gonolobinae, al annuli were found
mainly in some Stapelieae. The faucal annulus occurs immediately to the outside of the gynostegial corona
Oe, closer to the corolla lobes than the center of the flower). Annuli may be "interrupted" and reduced to
a ridge opposite each corolla lobe sinus (e.g., G. martinicensis Decne.; Fig. 3L) or “uninterrupted” and well-
developed (e.g., G. jamaicensis; Fig. 3Kiii). They are frequently pubescent, but not always, in contrast to the
always glabrous, cns APR coronas.
Gynostegial ost a oronas are quite varied in West Indian Gonolobinae (Fig. 3Ki-iii,
L), bare can bedescubed tly in terms of staminal (Cs) and interstaminal (Ci) segments. The coronas
have been interpreted as a “fusion” Games the Cs and Ci (Liede & Kunze 1993), although it remains un-
102 j tl tanical Insti Texas 2(
clear whether the combined structure in fact represents a true fusion of disparate elements (see Endress &
Bruyns 2000). In Gonolobus, the Cs region typically is raised and ridge-like, often meeting the lower portion
of the laminar dorsal anther appendages (Cd). There are no instances of free, ligulate Cs segments as seen
in other West Indian Gonolobinae taxa, such as M. ovatifolia (Griseb.) Woodson or M. pentactina Krings,
or three-dimensionally complex Cs segments as seen in M. tamnifolia (Griseb.) Woodson and M. oblongata.
Ci segments are single and cup-like in most West Indian Gonolobus species, and double (i.e., ligulate) only
in G. iyanolensis and G. martinicensis (Fig. 3L). The interstaminal ligules of the double coronas of the latter
two species are not positionally homologous with the staminal ligules seen in numerous species of Matelea,
such as West Indian M. ovatifolia and M. pentactina, or continental M. pubiflora (Decne.) Woodson. However,
some Matelea species, such as M. maritima (Jacq.) Woodson, also exhibit interstaminal ligules. In the Ascle-
piadoideae in general and West Indian Gonolobus in particular, the Ci region appears to serve as a holding
cup for nectar secreted from a primary nectary on the flanks of the filaments insi de the guide rail and in the
stigmatic champer (Christ & Schnepf 1985, 1988). Among West Indian Gonolobus species, defined second-
ary nectaries are evident—at least as far as can be determined from herbarium specimens—only in a few
species (e.g., G. dussii Krings). Kunze (1995, 1999) also found defined secondary nectaries in continental G.
chloranthus Schltdl. and G. fraternus Schltdl., as well as the gonolobinoid Matelea reticulata (Engelm. ex A.
Gray) Woodson and M. argentinensis. Secondary nectaries are epithelial, consisting of enlarged epidermal
cells enriched with cytoplasm (Kunze 1995). Epithelial nectaries on the filament flanks appear to be wide-
spread in Asclepiadoideae (Christ & Schnepf 1985; Kunze 1991; Kunze 1995).
The gynostegial stipe is generally edentate, although G. jamaicensis, G. stephanotrichus, and G. yourou-
maynensis have distinct teeth or “notches”. The stipal teeth or “notches” of all three species are distinct in
shape and occur in idi locations. Their homology is unclear.
Laminar dorsal dages.—Laminar dorsal amtner EE (Cd sensu Kunze 1995; Fig.
3Ki-ii, L-M) are restricted to Gondlabus s.l. or s.s., although it remains u whether they evolved once in
the most recent common ancestor of the former, or once in the ancestor of the latter and in the ancestor of
the Fimbristemma group within Gonolobus s.l. (Krings et al. 2008). Parsimony is equivocal on the question
(Krings et al. 2008). The only other genus exhibiting sr anther iM within Gonolobinae (and
Asclepiadoideae, fide Kunze 1995) is Fischeria, but the apr ther than laminar (Murphy
1986; Vethacke 1994; Kunze 1995). Laminar dorsal MA vary in shape from truncate to rounded to
strongly, divergently bi-lobed. They tend to be spreading, but are conspicuously (and spectacularly) erect in
mature flowers of G. stapelioides (Fig. 3Ki).
Style-heads.—Style-heads vary conspicuously in West Indian Gonolobinae, but tend to be essentially
planar (varying from somewhat convex to somewhat concave) in Gonolobus species in the area (Fig. 3Kii, L).
West Indian eons Lundi PED lack terminal style-head appendages, in contrast to other West Indian
ies such as itima, M. corynephora, M. rhynchocephala, and M. torulosa (see Krings
2006).
Pollinaria.—Pollinaria in Asclepiadoideae consist of a secreted corpusculum and two connected pollinia
(pollen sacs; Kunze 1994). The two pollen sacs are the result of a reduction in anther locules from four in
the more primitive Secamonoideae to two in the more derived Asclepiadoideae (Kunze 1996; Rapini et al.
2003: Liede-Schumann et al. 2005; Rapini et al. 2006). The pollinia are borne essentially horizontally in
West Indian Gonolobus species—as they are in most members of the Gonolobinae—and should be considered
broad, rather than long (Kunze 1995; Endress & Bruyns 2000; Fig. 3N). Only a portion of each pollinium is
fertile and hyaline, sterile portions are easily visible. The corpusculum in the Gonolobinae (based on studies
of Matelea reticulata and M. argentinensis) consists of solid side walls and a thick, three-layered floor (Kunze
1994). Kunze (1994) suggested that the formation of the side-walls originates in two primarily separated
strands of secretion which eventually merge into one compact wall. Caudicles are present (Fig. 3N), but
Kunze (1994) noted it was difficult to determine whether they are extensions of the outer flanks or new ad-
ditions. He suggested the latter, based on the lack of staining with either hematoxylin or safranin, although
Krings, Revisi f Gonolobus in the West Indi 103
noting that caudicle initiation in the two Matelea species occurs very early in ontogeny and directly from
the corpusculum, rather than apart from it.
Follicles.—Follicles in West Indian Gonolo! ies (as in most continental G
2001), when known, are 5-winged (Fig. 30), MM -— murications may be seen d the wings of
some taxa (e.g., G. stellatus). Some continental species of Gonolobus also exhibit 4-winged (G. albomarginatus
(Pittier) Woodson) or apparently 3-winged (G. incerianus W.D. Stevens & Montiel) follicles (Stevens 2001).
Winged follicles are also exhibited by other members of West Indian Gonolobinae, such as M linearipetala,
and the putative members of an ocellate complex M. acuminata, M. bayatensis, M. correllii, M. nipensis, M.
oblongata, M. rhamnifolia, and M. tigrina.
Seeds.—Seeds of West Indian Gonolobus species, as of most West Indian Gonolobinae, are essentially
planar and pyriform in outline (distinctly plano-convex in Matelea maritima and M. rubra (H. Karst.) Spell-
man & Morillo). Distal margins vary from entire to dentate or crenate (Fig. 3P). Comas are translucent.

HABITAT
In general, West Indian Gonolobus species occur in small gaps or openings in mid-elevation, moist or wet
forests on limestone derived soils. They are absent from high-elevation dwarf forests, coastal thickets, man-
groves, marshes, or dry forests. Occurrences are infrequent to rare and likely limited by available habitat.
Small gaps in minimally disturbed forests appear vital to seedling germination as vines are rarely encoun-
tered elsewhere. Changes in gap dynamics or forest condition, thus could have profound impacts on the
maintenance of Gonolobus populations. With the exception of G. youroumaynensis, the species have not been
found along roadside edges, where other vines (particularly Ipomoea L. spp. and Dioscorea L. spp.) are gener-
ally superior competitors and quickly form thick, tangled thickets. Gonolobus youroumaynensis was found
along a roadside patch of vegetation in St. Vincent, although it remains unclear whether the population is
competitive there or merely persistent following a colonization event. A population of Gonolobus iyanolensis
persists on top of Gros Piton in St. Lucia among boulders.
POLLINATION
As there have been no pollination biology studies on West Indian Gonolobus species, their pollinators remain
unknown. In fact, pollinators appear to be documented for only two species of Gonolobus range wide: G.
fraternus (Mexico and Central America) and G. suberosus (United States).
Kunze (1999) studied the pollination ecology of G. chloranthus and G. fraternus, but was able to observe
putative pollinators only on the latter. Pollinarium uptake was confi ] for two diptera species (Calliphori-
dae, Tachinidae), a bee (Apidae), and a wasp (Vespidae) (Kunze 1999). Other observed visitors included Apis
mellifera Linnaeus (Apidae) and unidentified butterflies (Lepidoptera) (Kunze 1999). However, pollinarium
removal by these could not be verified. Corpuscula were removed by the wasp and bee by their legs, and by
the bee and the flies by their probosces. Foraging behavior differed among the observed species, with the
wasp and bee prefering upper regions of the studied vine, and the flies, the middle and lower.

Lipow and Wyatt (1998) also Se G. suberosus, but despite daily and nightly searches were
pollinators.
Gonolobus suberosus appears to DESCH considerable variation in the numbers of flowers per individual
plant, the number of fl , and the number of infl individual plant (Lipow
Sr Wyatt 1998). Only a mall fraction of P monitored by Lipow and Wyatt (1998)—less than 596—were
pollinated and per flower removal rate of pollen was only 0.31. This rate was less than previous reports in
other asclepiads (Table 1).
Ollerton and Liede (1997) noted that subtribe Gonolobinae appears distinct in being predominantly
dipteran pollinated, although this claim was based on only five Matelea species in the southeastern United

examined species also studied by Drapalik (1969) and found additional dipteran floral visitors (Liede 1994;

INSECTS HOSTED
There are no published records of insects hosted by West Indian Gonolobus species known to the author.
However, a few records of primarily dipterans and lepidopterans have been published for continental spe-
cies in the genus. Castrejon-Ayala and Camino-Lavin (1991) reported Gonolobus sorodius, nom. nud., as
host for papaya fruit fly (Toxotrypana curvicauda Gerstaecker)—the principal insect pest of commercial
papaya (Carica papaya L.). Norrbom (unpubl.) suggested this plant may be Gonolobus barbatus Kunth. Baker
et al. (1944) reported another asclep host plant of papaya fruit fly—a wild species known as talayote or
talayotillo in northeastern Mexico (Santa Engracia and Cañon de Rosario). Castrejón-Ayala (1987) suggested
the plant may be a species of Gonolobus and Landolt (1994) suggested perhaps G. erianthus DC. Gonolobus
salvinii Hemsl.—commonly called champeron in Guatemala—may yet be another host for the papaya fruit
fly (Norrbom & Muñiz, unpubl.).
Capinera (2005) reported “Gonolobus sp." among hosts for the saltmarsh caterpillar (Estigmene acrea
(Drury))—a species ranging from Canada to Central America. An unidentified species of Gonolobus was
reported as host for Erinnyis obscura obscura (Fabricius) —a sphingid found in Amazonas, Brazil (Silva Motta
& Xavier-Filho 2005).
There are a number of reports of Gonolobus laevis Michx. serving as host plant for various lepidopterans,
including Danaus gilippus Cramer and D. plexippus (Linnaeus), however G. laevis belongs to the Cynanchinae,
not Gonolobinae, and should be recognized as Cynanchum laeve (Michx.) Pers. (Liede & Tauber 2002).
SEED DISPERSAL
The follicles of known West Indian Gonolobus species are smooth and uniformly 5-winged, dehiscing along
a solitary suture between two wings to release the comose seeds. Seeds are very light (Table 2) and can
travel on slight breezes. Unfortunately, mature follicles have been do cumented by collections for only three
Krings, R ESI Er ILL H al 3AF PE | je 105
of the ten species of West Indian Gonolobus (Table 2). Immature follicles are known for G. stapelioides (see
Additional specimens examined). The paucity of fruiting collections is echoed in West Indian Gonolobinae
as a whole. Follicles have been collected for less than half of the estimated fifty species in the West Indies
(Krings, unpubl.). The low rate of fruit collections may be due to naturally low levels of fruit set in the
subtribe (Lipow & Wyatt 1998), as well as collector habit, flowers being necessary for most species level
determinations. Lipow and Wyatt (1998) suggested that low fruit set in Gonolobinae may be attributable to
pollen limitation. Less than 5 % of flowers monitored were pollinated and only a single fruit matured from
352 flowers on 13 plants (Lipow & Wyatt 1998).
CHROMOSOMES
There are no published reports of chromosome numbers in West Indian Gonolobus or Gonolobinae. Previ-
ously published reports for continental Gonolobinae, including continental Gonolobus, show the same basic
chromosome number x = 11 that predominates the subfamilies Asclepiadoideae, Periplocoideae, and Se-
camonoideae (Albers & Meve 2001). Only 6% of 672 species surveyed in the three subfamilies by Albers and
Meve (2001) were polyploid and deviations (reductions or increases in chromosome numbers) were found
only in the Asclepiadoideae. No deviations within the Gonolobinae from 2n = 22 were found by Albers and
Meve (2001), although only five species in four genera were included from the subtribe in their survey.
USES
As there are no published accounts of human uses of West Indian Gonolobus species known to the author, a
survey of uses in other areas may be of interest to the reader. The Ecuadorian endemic and IUCN Vulnerable
(VU) listed Gonol onus zip mane monto has been reported to be used by the Saraguro native people as a
medicinal plant (sp ifi ), under the name sacha ango (Pitman 2003). Unspecified medicinal
uses are also reported for boum yucatanensis (Woodson) W.D. Stevens, a taxon described in Trichostelma
Baill. (Durán García et al. 1997). Standley and Williams (1969) noted that the tender, young fruits of Gonolo-
bus species are commonly used as vegetables in Guatemala, and may be available in local markets under
the name cuchamper, although this name has also been applied to the fruits of related genera. Specific uses
are noted by Standley and Williams (1969) for G. salvinii (tender follicles eaten raw when almost mature,
and cooked and eaten at almost all stages of growth) and G. stenanthus (Standley) Woodson (young follicles
boiled or otherwise cooked with sugar to make sweetmeats or dulces). Stevens (2005) noted that "most, if
not all, species of Gonolobus have fruits that are eaten when young, either raw or cooked." Numerous studies
have examined potential medicinal properties of latex in Asclepiadinae (Asclepias L.: Liggieri et al. 2004;

CONSERVA TION
Human disturbance disproportionately affects infrequent plant species more than common taxa as further
reductions of already low population si y not be sustainable (Lawton 1993; Casagrandi & Gatto 2000;
Hendrix & Khyl 2000; Benitez Walvis & Martinez Ramos Sch West ud Gonolobus species, as many
other species of Asclepiadoideae (Kunze & Liede 1991), appear to be quite i t, if not rare, and are in
need of serious survey (particularly in Cuba and the Lesser Alles to Ste a conservation status
However, some provisional remarks are possible, based on study of collections and field observations as-

The habitat requirements of West Indian Gonolol in need of
evidence suggests that most eS are Ke limited to Small gaps or openings in mid- dyi, moist or
wet forests. They appear to be p long forest edges. The combined infrequency of occurrence
of individuals, poor competitive SCH long edges, ely low pollination and fruit set rates (see Pollination
and Seed Dispersal SE) ane meee d SE SE or openings in specific forest community types, suggests
that Gonolol erable to loss of habitat. This is of particular concern consid-
ering the high rate of island endemis — the species. Eight of the ten West Indian Gonolobus species
are endemic to single islands (Fig. 1). Gonolobus dussii occurs on two islands and G. stephanotrichus occurs
on three islands. Seven of the ten West Indian Gonolobus species are known from five or fewer collections or
localities (Table 3). None of the remaining three species appears to be known from more than ten localities.
Provisional estimates of conservation status according to the criteria outlined in Version 3.1 of the IUCN
Red List Categories and Criteria (IUCN 2001) and Version 6.1 of NatureServe Conservation Status Ranks
(NatureServe 2006) are provided in Table 3. Provisional estimates are based on historical collections, the
number of known localities, whether taxa are known from protected areas, and inferred habitat or popula-
tion changes. These estimates need to be followed by targeted survey to better establish the conservation
status of the species.

synonym for his G. macrophyllus, Perry (1938) proposed the combina-
tion G. gonocarpos as the correct name for Reen sG. — M Recent study found the entity variously
known as G. gonocarpos or G. macrophyllus cons pecific with G. suberosus (Krings & Xiang 2004, 2005). The
latter name has priority following Reveal and Barrie (1992).
Some Robert Brown names have sometimes been incorrectly dated. In 1810, a preprint of his "On the
Asclepiadeae, a Natural Order of Plants separated from the Apocinae of Jussieu" was made available. This
same work later appeared in the first volume of the 1811 Memoirs of the Wernerian Natural History Society
(Stearn 1960; Stafleu & Cowan 1976; Mabberley 1985). Although sometimes incorrectly cited from the first
reading of the paper in 1809, communication at public meetings does not constitute effective publication
(Forster 1991; Greuter et al. 2000; McNeill et al. 2006). Names should also not be ascribed to the 1811
appearance of the Memoirs of the Wernerian Natural History Society but rather to the preprint released in
1810. Thus the combination Gonolobus suberosus (L.) R. Br. should be cited as above, rather than in Mem.
Wern. Nat. Hist. Soc. 1:35 (1810). As Brown's 1810 combination in Asclepiadeae is validly published (by
definite association of the final epithet with the genus name), it takes priority over the Schultes combination
in Systema Vegetabilium 6:59 (1820).

Notes.—Gonolobus dussii can be distinguished from G. youroumaynensis of St. Vincent by the short
pedicel trichomes, the edentate stipe, and the adaxially glabrous corolla lobes. The gynostegial coronas of
G. absalonensis, G. dussii, and G. youroumaynensis are most similar to each other among Lesser Antillean
Gonolobus species, but G. dussii uniquely exhibits two distinctly raised and rounded mounds in the inter-
staminal position (Fig. 5). The mounds appear very close and near ridge-like in Martinique specimens, as
well as Duss 3775 of Guadeloupe. Additional collections are needed to determine the extent of variation in
the coronas and to evaluate whether additional taxa are represented.

Distribution.—Gonolobus iyanolensis is apparently endemic to St. Lucia (Fig. 1), occurring in seasonal
deciduous woods from 180—400 m in elevation. An established population occurs on Gros Piton. Roger
Graveson (pers. comm.) noted having seen vines away from the Pitons, but that they have not established
themselves well. Woodland boundaries and recent forest openings appear to be the prefered habitat.

Notes.—Roger Graveson (pers. comm.) noted that the collection date is i t on the label of his col-

species that shares this corona pe in the a area is G. martinicensis. (Fig. 8). In contrast to the robust-flowered
G. iyanolensis, G. martinicensis exhibits distinctly more slender flowers with elongate-campanulate bases (ca.
2 mm long) that are longer than wide (as wide as long or wider than long in G. iyanolensis) and a narrower
gynostegial corona (see key). The distinct dorsal ridge of the narrow upper ligulate corona lobe of the Ci in
G. iyanolensis has also not been seen in G. martinicensis, which is either plane in the homologous position or
exhibits a a sightly raised bump.

Taxon concept mapping.— = G. rostratus sensu Schlechter (1899); = G. jamaicensis sensu Adams (1972).
Notes.—Gonolobus jamaicensis was proposed by Rendle (loc. cit.) as a nomen novum for the Jamaican
endemic t Schlechter (1899) treated as G. rostratus (Vahl) R.Br. Not only did Robert Brown never make
the combination attributed to him (see Mem. Wernerian Nat. Hist. Soc. 1:35. 1810), but the true Gonolobus
rostratus (Vahl) Schult. is only known from Trinidad (and perhaps South America). It is based on the type
of Cynanchum rostratum Vahl. Because Rendle corrected a misapplication, his name—G. jamaicensis—is
a new species name, not a nomen novum as he mistakenly stated. A nomen novum is an avowed substitute
(replacement name) for a validly published but illegitimate name, the type of which would be the same as
that of the name which it replaced.

(1972
Notes.—An appropriately labeled red type folder is present at P, but was found empty during visits in
2004 and 2006. In the absence of the specimen, G. stapelioides is neotypified here. Schlechter (1899) noted
that Hamilton (loc. cit.) likely mixed up the localities when describing G. stapelioides and G. virescens Ham.
The locality of the former was given as ER ana that of the EEN as Jamaica. However, neither entity is
known by any other speci from t] land indicated in t tol In addition, Hamilton's
description of ovate and acute corolla pubes would be an inaccurate decctiption of the Jamaican entity to
which Schlechter (1899) and subsequent workers have applied the name G. stapelioides. However, Hamil-
ton’s corolla lobe description is a very nice match of the type of G. virescens. Thus, it appears that while the
localities were mixed up, Hamiiton’s protologues clearly allow association of the name G. stapelioides to the
Jamaican entity and G. virescens to the Tobagoan entity as Schlechter (1899) proposed.
Gonolobus stapelioides is immediately recognizable by the white Cd segments that are fully vertical at
maturity (Fig. 9E, F

Phenology.—Flowering in March, May, June, and July.
Distribution.—Gonolobus waitukubuliensis is endemic to Dominica (Fig. 1). It has been found primarily
in middle elevation rainforests (ca. 609-1067 m; 2000-3500 ft). Like most West Indian Gonolobus taxa, G.
waitukubuliensis appears to require small gaps in mature forests. It does not appear to be able to compete in
large gaps or roadside edges in which other vines quickly become dominant. It is rather infrequent to rare,
especially in mature forests with few gaps.

Notes.—Gonolobus waitukubuliensis is immediately gnizable among Lesser Antillean Gonolobus
species by the combination of a distinctly raised, completely circular faucal annulus (ca. 0.5 mm tall), an
erect gynostegial corona that appears quite folded apically, and a relatively tall gynostegial stipe (1-1.5
mm). It shares with G. absalonensis, G. iyanolensis, and sometimes G. martinicensis, the absence of hairs from
the abaxial corolla lobe surface. The trichomes of the pedicel are fine and not as long (ca. 0.3 mm) as in G.
iyanolensis (0.3-0.9 mm

the windward side of the island at the foot ER a Soufriére in the Orange Hill Estate area. Vines were found
take amidst banana and pigeon pea plantations. Vines were not found
growing along the road to the water i
along the trail to the crater of La Soufrière. However, only a half day was spent searching this trail and they
could have been overlooked.

Notes.—Gonolobus youroumaynensis is readily recognizable among Lesser Antillean Gonolobus species
by the combination of a single, prostrate-undulating gynostegial corona exhibiting a small bump towards

DOUBTFUL AND EXCLUDED NAMES
The following list includes names that are excluded from Gonolobus s.s. based on their morphology (e.g.,
130 J | of the Botanical R h Institute of Texas 1(2)
lack of laminar dorsal anther appendages), and names of uncertain status. Two new combinations are made
below: Matelea dictyopetala and M. pubescens.
Gonolobus bakeri Schltr., Symb. antill. 7(3):341. 1912. Tee: CUBA: Cult. in Santiago de las Vegas, May 1907, Baker 7286
OLOTYPE: location unknown
Gonolobus bakeri is apparently only known from the type collection, which has not been located despite
query of nearly one hundred institutions known to house West Indian collections. If the specimen was at
B, it may have been destroyed in WW II. The position of G. bakeri appears uncertain. Schlechter does not
describe dorsal anther appendages in the protologue. Combined with his note that the species is "mit G.
variifolius Schltr. [now Matelea variifolia (Schltr.) Woodson] am náchsten verwandt," there is reason to believe
that G. bakeri may better belong in Matelea. Matelea variifolia clearly lacks laminar dorsal anther appendages
and also exhibits suborbicular corolla lobes. It is known only from Puerto Rico (Schlechter 1899; Acevedo-
Rodríguez 2003, 2005). As the single specimen representing G. bakeri was cultivated in Cuba, it may be that
the species is merely a pubescent form of M. variifolia. Among West Indian Gonolobus s.s. (if not the entire
genus), G. bakeri would be the only species with suborbicular corolla lobes.

Matelea BEE is apparently known only from the type collection, which has not been located despite
query of nearly one hundred institutions known to house West Indian collections. Ifit was at B, it may have
been destroyed in WW II. Thus, the species can be placed solely based on the protologue and past treat-
ments. Although Krings et al. (2005) maintained the taxon in Gonolobus, the combination in Matelea may
be more correct based on the glabrous, reticulate corolla lobes and very narrow, linear-lanceolate leaves
(0.5-0.7 cm wide)—a leaf form quite atypical for Gonolobus. The description of the corolla lobes as being 9
cm long, is likely a print-setting error to be corrected to 9 mm. Grisebach (1866) did not mention laminar
dorsal anther appendages in his protologue for G. tigrinus var. angustifolia and, upon reconsideration, it
is unclear to me whether Schlechter (1899) was refering to them or not [italics mine]: *Diese Art ist trotz
ihrer habituellen Aehnlichkeit mit G. tigrinus Griseb. von diesem vollstánding verschieden. Die Blátter sind
schmaler, die Blúthen grösser, die äussere Corona ganz verschieden und die Schuppen der inneren Corona
viel deutlicher vom Antherenrúcken abgehoben, Gei von oben gesehen, in der Mitte nicht ausgerandet,
sondern eher verdickt.” 1 am hesistant to pres tinct, as another Cuban Gonolobinae species—
G. stephanotrichus—was recently oral in the country m having been known from the island only
from the type, collected between 1860 and 1864 (Krings et al. 2005).

Krings, Revision of Gonolobus in the West Indi 131
Gonolobus haitiensis P.T. Li is a nomen novum for Gonolobus stipitatus Alain (Phytologia 64:345. 1988). It is
here reduced to synonymy beneath Matelea crispiflora, as its type (Ekman H4693) clearly belongs with Poicil-
lopsis crispiflora Urb. However, see also note for Gonolobus membranaceus Schltr.

The location of the type remains unknown. Ekman H4693 (IJ!) is labelled Gonolobus membranaceus. The
specimen consists of mostly stem and 3-4 leaf fragments held in a fragment pocket. It appears to match
Poicillopsis crispiflora Urb. Gonolobus membranaceus is likely very closely related to Matelea haitiensis as, based
on the protologues, the two appear to differ only in the shape and apices of the leaf blades and calyx lobes.
Additional collections and discovery of the type may prove them synonymous.

Sometimes cited as Gonolobus ottonis Walp. (Ann. Bot. Syst. 5:502. 1859). However, Walpers (1859) clearly
cited G. ottonis C. Koch & Bouche and should not be considered author of a homonym. Walpers (1859)
repeated Koch and Bouche's citation: “Ex insula Cuba reportavit Otto.” However, Schlechter (1899) thought
that the specimen collected by Otto (apparently formerly at B) was from Caracas, Venezuela, not from Cuba.
The location of the type is unknown.

INTRODUCTION
Subtribe Gonolobinae (A Asclepiadoideae) j| bout fifty in the West Indies, here
defined to include the cies and Lesser Antilles: the Bahamas, ee Kë Tobago, Aruba and the Neth-
erland Antilles, and the Cayman Islands. Evid plast (Rapini et al. 2003; Liede-Schumann
et al. 2005; Rapini et al. 2006; Krings et al. 2008) and nuclear genomes (Krings et al. 2008) supports the
monophyly of Gonolobinae. Generic circumscriptions remain poorly defined and it is likely that the broad
concept of Matelea Aubl. sensu Woodson (1941) is not monophyletic. Genera referred to the subtribe with
representation in the region include Fischeria DC., Gonolobus Michx., Matelea (incl. Ibatia Decne., Jacaima
Rendle, Poicilla Griseb., Poicillopsis Schltr., Ptycanthera Decne.), Macroscepis Kunth, and Metalepis Griseb.
(Fontella & Schwarz 1981a; Kunze 1995; Liede 1997; Morillo 1997; Rapini et al. 2003; Liede-Schumann et
al. 2005; Rapini et al. 2006). Subtribal position has been most controversial for Metalepis, which some work-
ers have also placed within in a broad concept of Cynanchum L. (Woodson 1941; Spellman 1975; Sundell
1981). Recent evidence places it basal to a well-supported Metastelmatinae-Oxypetalinae-Gonolobinae clade
(Liede & Kunze 2002; Liede-Schumann et al. 2005). The last regional treatment of Gonolobinae is now
over 100 years old (Schlechter 1899) and a number of new species have been described by various workers,
including Britton, Krings, Liogier, Proctor, Spellman, Urban, and Woodson (see ne 2005b, 2006, 2007,
as well as the present study). Recent effort as part ofa l tudy of Gonolobinae and treatment
for the Flora de la República de Cuba (Krings 2005a—d, 2006, 2007 Runes et al 2003, iun & Fantz 2006;

Fourteen lectotypes and one neotype are designated here. A new name and a new combination in Matelea
are proposed for Jacaima parvifolia Proctor and J. costata (Urb.) Rendle var. goodfriendii Proctor.
METHODS
Names in West Indian Gonolobinae were compiled from searches of the TROPICOS database (http://www.
tropicos.org) for species with West Indian types, as well as from review of pertinent literature (i.e., Grisebach
1862, 1866; Duss 1897; Schlechter 1899; Millspaugh 1902; Boldingh 1909, 1914; Woodson 1941; Moscoso
1943; Cheesman 1947; Alain 1957; Gooding et al. 1965; D'Arcy 1967; Adams 1972; Little et al. 1976; Correll
& Correll 1982; Proctor 1984; Howard Ee We 1991; Liogier 1994, 1995; Fournet 2002; Acevedo-
Rodríguez 2005). Protologues were compiled from held at the North Carolina State University Libraries
or obtained through inter-library loans. Subsequently, queries were made to ninety institutions known to
house West Indian collections—of which sixty-five responded with either loans, digital images, or negative
search results (see Acknowledgments). Visits were also undertaken to BM, BSC, DUKE, HAC, HAJB, IJ, K,
UCWI, UPRRP, US, and P.
Nearly half of the species names in West Indian Gonolobinae can be attributed to three German work-
ers: August Heinrich Rudolf Grisebach (1814—1879), Friedrich Richard Rudolf Schlechter (1872-1925), and
Ignatz Urban (1848-1931). The former worked from the University of Góttingen (GOET) and the latter two
from the Botanical Garden and Museum Berlin-Dahlem (B).
The general philosophy followed herein, is that for taxa described by Grisebach, applicable specimens
judged original material at GOET are considered holotypes—although, in a strict sense, Grisebach did not
designate them as such, although his use of them is evident by his notes and annotations. However, typi-
fication of Grisebach names based on collections by Charles Wright (1811-1885) can be problematic, as
collections cited under a single collection number frequently represent gatherings from different localities
and different times (Howard 1986, 19892). The philosophy adopted herein is that Grisebach names based
on Wright collections should be lectotypified when (1) it can be shown that specimens distributed under
a single number represent gatherings from different localities at different times, and/or (2) no specimen of
a Wright number remains extant at GOET. When it cannot be shown that gatherings came from different
localities and different times, duplicates of a Wright number designated lectotype are considered isolecto-
types (see Krings & Fantz 2006). When it can be shown that gatherings came from different localities and
different times, duplicates of a designated lectotype are treated as syntypes.
Urban described West Indian taxa largely based on specimens received by him from Erik Ekman (Cuba
and Hispaniola), William Harris (Jamaica), and Walter Elias Broadway (Trinidad, Tobago, and Grenada).
For these taxa, holotypes are presumed to have remained at B until their destruction in a fire in World War
IL. Thus, lectotypes are chosen for Urban names from duplicates of numbers cited in his protologues.
RESULIS
Overview.—Names of novelties in West Indian Gonolobinae can be attributed to seventeen workers (Table
1). The majority of taxa were described during four phases of intensive interest in the region that occurred
at ca. 20-30 yr intervals over the past 140 yrs. The first phase was dominated by Grisebach and based on
the collections of Wullschlagel (Antigua), Charles Wright (Cuba), Imray (Dominica), and Alexander, Higson,
Macfadyen, and Purdie (all Jamaica). Important works resulting from activity during this phase include the
Flora of the British West Indian Islands (Grisebach 1862) and the Catalogus Plantarum Cubensium (Grisebach
1866). The second phase was dominated by the activity of Schlechter—based primarily on collections by
Broadway (Grenada; Trinidad & Tobago), Eggers (Tobago), Poiteau (Haiti), Sintenis (Puerto Rico), and Wright
(Cuba)—and Urban—based primarily on the collections of Broadway (Tobago), Buch (Haiti), Ekman (Cuba
& Hispaniola), and Harris ww d e most important relevant work resulting from this later period of
activity is Urban's multi-volume S; e Antillanae (1898—1928). The third phase was dominated by Liogier
(a.k.a. Hermano Alain), ND SES more West Indian SE SES novelties based on his own collec-
tions than any other worker before or since Additional species described by Liogier are based on collections

by Ekman (Hispaniola) and Howard (Dominican Republic). Important works resulting from his efforts or
contributions include floras of Cuba, Hispaniola, and Puerto Rico (Alain 1957; Liogier 1994, 1995). The
fourth phase of interest is the result of current efforts undertaken by the present author (Krings 2005b,
2006, 2007). New discoveries during this phase are based on collections by Eggers (Dominica), Ekman
(Hispaniola), Graveson (St. Lucia), Krings and Springer (St. Vincent), Liogier (Dominican Republic), Marcano
and Jiménez (Dominican Republic), and Quentin (Guadeloupe). No new names in West Indian Gonolobinae
resulted from R.A. Howard's efforts toward his Flora of the Lesser Antilles (Howard, 1989b).
List.—Names are listed index style and include legitimate, illegitimate, and misapplied names. They are
arranged strictly alphabetically by basionym or combination. The most recent combination for a respective
name follows the basionym (3). Currently accepted names are in bold or specified under “Notes.” Under the
name, the locality and/or collector the type is given as it appears in the protologue. Type specimens seen
and verified by the author are indicated by an exclamation point (‘!’) following the herbarium of deposit. The

Protologue: Neither specimens, nor locality cited.
Type: Herbar. Du Jacquin, 2 Insulae Caribaea, De Ponthieu (Lectotype designated by Krings & Saville
2007: BM).
Notes: Only a single sheet of Asclepias ala was located that could qualify as belonging to the origi-
nal material. Eight fragments, all Asc] itima, are mounted on a single sheet held at BM and barcoded
(BM000834432). A handwritten dies on the top left of the back of the sheet reads "Herbar. Du Jacquin."
followed by “2 Insulae Caribaeae. De Ponthieu.” Based on the note, the fragments appear to represent two
elements, but they cannot be delineated. A dehisced follicle is mounted along with leaves in relatively good
condition and a few flowers in poor condition. Fruits and flowers are not mentioned by Jacquin in the pro-
tologue, and these elements may represent the collection later combined with the vegetative fragment used
for the protologue. Consid that this sheet app t the only remaining collection of Asclepias
maritima from the herbarium af Jacquin, it was desieneted lectotype by Krings and Saville (2007).

Notes: Most recent authors have accepted this entity under the name Matelea denticulata (Vahl) Fontella &
E.A. Schwarz. However, in a recent phylogenetic analysis based on chloroplast and nuclear data, the taxon
emerged in a clade of Gonolobus s.l. (Krings et al. 2008) and should be recognized as Gonolobus denticulatus
(Vahl) W.D. Stevens in a broad interpretation of the genus.

oodson, Ann. Missouri Bot. Gard. 28:222. 1941
Notes: Kee aos have mistakenly attributed the combination in Cynanchum to Linnaeus” Syst. Nat.
(1767). However Linnaeus (1767) clearly referenced Jacquin (1763). In Syst. Nat. (1767), he wrote: *C. caule
volubili, fol. ap BH Se tomentosis, pedunc. Aggregatis. Mant. 54.” The Mantissa plantarum
(Mant.) pul lix to volume 2 of his Syst. Nat. (1767). In the Mantissa, Linnaeus
(1767) provides further SE cc to Jacq. amer. 86, t. 56, and describing corollas of C. maritimum as
‘atropurpurea. Although C. maritimum is described on pages 83 and 84 in Jacquin’s Select. Stirp. Amer. Hist.
(1763), rather than on page 86 as cited by Linnaeus (1767), the illustration reference (plate 56) is correct
and is not inconsistent with plants known most recently as Matelea maritima in the West Indies. Thus, it is
clear that Linnaeus accepted Jacquin's combination and was not himself proposing a new one. Continued
citation of Cynanchum maritimum L. is incorrect.
See Asclepias maritima Jacq.
Cynanchum maritimum (Jacq.) L., Syst. Nat. 2:192. 1767, err. cit. [2C. maritimum (Jacq.) Jacq., see above].
Notes: Linnaeus (1767) never made this combination mistakenly attributed to him by subsequent workers.
Cynanchum rostratum Vahl, 2 Bot. 3:45. 1794. = Gonolobus rostratus (Vahl) Schult. in Roemer &
Schultes, Syst. Veg. 6:61. 1820.
Protologue: “In insula Trinitatis legit Dn. v. Rohr,” loc. not cited.
Type: Trinidad, (von Rohr?) Hb. Liebmann (HOLOTYPE: C [IDC microfiche photo: Vahl herbarium nr. 17:111,
51]; isoryre: BM!).
Notes: Although Stafleu and Cowan (1986) ven that wane S SE Geen are ipis on the Forsskál
material at C; G is not listed in the i IDC fiche of the Forsskál
herbarium. However, there is a specimen in the Vahl befharium corresponding to Cynanchum rostratum.
The specimen label identifies it as having been part of the Hb. Liebmann at some point, however the hand,
identifying the collection as Cynanchum rostratum, belongs to Vahl. Von Rohr is not indicated on the label.
Cheesman (1947) mistakenly considered *Gonolobus rostratus R.Br. sens. Griseb Fl. 420" a synonym
of *Matelea viridiflora (G.EW. Meyer) Woods.” However, the latter clearly corresponds to Matelea denticulata
(Vahl) Fontella & E.A. Schwarz based on Cheesman’s description (e.g., “callyx] lobes lanceolate,” "corolla
[...] lobes ovate,” “anthers without dorsal appendages”) and not to Gonolobus rostratus sensu Grisebach
(1862) (e.g., “calyx [...] segments ovate,” "corolla [...] segments lanceolate-linear”). Grisebach’s (1862) taxon
(also from Trinidad) is clearly referable to G. rostratus (Vahl) Schult. The two taxa are difficult to confuse by
anyone familiar with them. The combination in Gonolobus is to be attributed to Schultes as Robert Brown
never made the combination erroneously attributed to him by some authors such as Grisebach (1862) and
Schlechter (1899).

the only species of Fischeria she recognized from Trinidad.

Notes: In contrast to Grisebach himself (loc. cit.), Schlechter (1899) believed that Grisebach's F. multiflora
did not belong to Decaisne's Brazilian species by the same name, but rather to F. havanensis Decne. Chees-
man (1947) accepted this as well. Murphy (1986) considered F. havanensis Decne. a synonym of F. scandens
DC., but did not recognize this taxon from Trinidad, the locality from which Grisebach (loc. cit) cited his
F. multiflora (based on Purdie and Crueger collections). Murphy (1986) recognized only F. stellata (Vell) E.
Fourn.—under which she submerged F. multiflora Decne.—from the island.

Notes: Based on Schlechter's (1912) description, Gonolobus grenadensis Schltr. is a synonym of Gonolobus
denticulatus (Vahl) W.D. Stevens. Schlechter (1912) considered it a close relative to G. ciliatus Schltr. (also
a synonym of G. denticulatus), from which he distinguished it only by larger faves and flowers. Howard
(1989b) also treated G. grenadensis as a synonym of G. denticulatus, although confusing it with G. martinicen-
sis in key and description (though not in illustration). Unfortunately no original Bate of G. grenadensis
could be located. Proctor 17225 (IJ) appears to be the only extant specimen of this taxon from Grenada. It

Notes: Ekman H4693 (IJ!) is labelled Gonolobus membranaceus. The specimen consists of mostly stem and
3-4 leaf fragments held in a fragment pocket. It appears to match Poicillopsis crispiflora Urb. Gonolobus mem-
branaceus is likely very closely related to Matelea haitiensis as, based on the protologues, the two appear to
differ only in the shape and apices of the leaf blades and calyx lobes. Additional collections and discovery
of the type may prove them synonymous.

Type: Hispaniola: ‘St. Domingue, Bertero s.n. (Lectotype designated by Krings 2006: P!; isoLecToTYPE: G-DC

Notes: Bertero collections were among specimens in the fragmented Sprengel collection acquired by B
in 1890, but no Bertero specimen corresponding to G. pauciflorus was found extant at that institution. As
neither extant duplicate of Bertero s.n. at either G-DC or P corresponding to G. pauciflorus bears the hand of
Sprengel and as no other Bertero material corresponding to the taxon has been located at the other institu-
tions queried (see Acl led ts), itis assumed that the holotype was destroyed. Consequently, having
been able to examine the Se at P, but only the microfiche of the specimen at G-DC, Krings (2006)
designated the sheet at P lectotype for G. pauciflorus.

Type: Jamaica, Macfadyen s.n. (HOLOTYPE: GOET!; Isotype: KT).
Notes: The GOET specimen consists of an unmounted section of stem with five nodes, but only three de-
veloped leaves. A fourth developed leaf and a fragment of a fifth are loose in the pocket. A smaller fragment
pocket contains floral parts. Macfadyen s.n. (K) is a superior specimen relative to Macfadyen s.n. (GOET) in
bearing many more leaves, as well as an openly pressed flower kept in the fragment pocket. Both the K and
GOET specimens are annotated in Grisebach’s hand.

Protologue: “Jamaica!, Al., S. Anns, near Moneague,” loc. not cited.
Type: Jamaica, R.C. Alexander s.n. (HOLOTYPE: GOET!).
Notes: See Krings (2005a) for a discussion of the morphology of this taxon. The type locality was visited
on an expedition to Jamaica by the present author and Dale Suiter in March 2006. However, the area was
unfortunately flooded (houses under 10—15 feet of water) and inaccessible. The species was not observed on
any of the access roads up to the flooded valley. Dr. George Proctor noted collecting a specimen in a narrow
patch of woods between a road and a pasture. The area appears to be in similar condition currently, with
many pastures separated from rural roads by narrow patches of woods.
Gonolobus rostratus (Vahl) Schult. in Roemer & Schultes, Syst. Veg. 6:61. 1820.
Notes: Schultes (1820) cited Vahl's protologue of Cynanchum rostratum (see above) and attributed the com-
bination in Gonolobus to Robert Brown. However, as Brown never made the combination in Gonolobus that
has been attributed to him, Schultes should be considered the author of the valid combination.
See Cynanchum rostratum Vahl.
"Gonolobus rostratus" auct. non (Vahl) Schult.: Schlechter in Urb., Symb. Antill. 1:284. 1899.
Notes: Schlechter (1899) mistakenly attributed a Jamaican entity to the name Gonolobus rostratus (Vahl)
R.Br., for which Rendle later proposed the name G. jamaicensis (see above). Robert Brown never made this
combination attributed to him (see Memoirs of the Wernerian Natural History Society 1:35. 1810).

Notes: Schlechter (1899) noted that there was likely a label mix-up | the Jamaican entity G. stapelioides
and the Tobagoan G. virescens Ham. It would indeed be unlikely for G. stapelioides to be limited in distribu-
tion to Jamaica and Tobago. The taxon is not represented by any other specimens from Tobago. Similarly,
G. virescens is not known from Jamaica by another specimen. A neotype is proposed as the holotype could
not be found.

Notes: Á new name is required as a new combination in Matelea is blocked by M. parvifolia (Torr.) Woodson.
As Proctor 37887 (IJ) is labelled isotype, it is assumed that the GH duplicate was intended to serve as the
holotype. Dr. Proctor accompanied the current author, Dale SEN and ER Campbell, on an expedition
to the type locality in March of 2006. At the time tl ibed the area was called Broom Hall and
the valley was mostly in pineapple cultivation (Godo pers. comm.). On a change of ownership, the area
is now mostly in coffee and under the name Baron Hall. Although the hills maintain forest cover, much is
disturbed and has either been converted to coffee or is in the process of conversion. Specimens of J. parvi-
folia were not located. There are forests not owned by Baron Hall which are part of the endemic Peckham
complex and may retain populations of J. parvifolia, but further research is needed.

legitimized the latter's nomen in schedula. Three sheets were cited in the PROTOLOGUE: R. & E. Howard 8512

latter collection (the paratype), which incidentally was also collected by both Howards, contains material that
clearly does not belong to the holotype and isotype. Although also glabrous, leaves of R. & E. Howard 8590
exhibit: (1) more numerous secondary veins, and (2) secondary veins nearly straight (vs. ascending in R.&
E. Howard 8512). The seeds associated with R. & E. Howard 8590 are also: (1) significantly longer (11-11.6
mm vs. 5 mm in R. & E. Howard 8512), (2) of a thin papery texture (vs. hardened in R.& E. Howard 8512), and
(3) lack the distally swollen margin seen in Howard 8512 (and other West Indian Matelea species). Although

is Ekman H1933 (EHH nv., K!, S!): Haiti, Morne de la Selle, Furcy, 1540m, in Buchs [sic] Botan. Garden, 17
Sept 1924. The sheets at K and S are in exceedingly good condition, bearing numerous leaves and flowers.
The sheet at EHH has not been seen, but is listed here based on the catalogue provided by: http://www.

Names of uncertain application or excluded from Gonolobinae. The following names include those
for which neither protologues nor types could be obtained, or for which the specimens do not belong in
Gonolobinae. Names of the former category have long been placed in synonymy by authors of treatments
of West Indian Gonolobinae (e.g., Schlechter 1899; Alain 1957).
Cynanchum. crispiflorum Sw., Prodr. 52. 1788. = Fischeria crispiflora (Sw.) K. Schum., Nat. Pflanzenfam
4(2):230. 1895.
Protologue: “India Occidentalis, Jamaica,” loc. not cited.
Type: Plum., Pl. amer. 216, f. 1. 1759.
Notes: According to Murphy (1986), the name Cynanchum crispiflorum Sw. (and various subsequent combina-
tions in Fischeria) has been misapplied by various workers to what she recognized as Fischeria scandens DC.
Murphy (1986) excluded the type of C. crispiflorum Sw. from Fischeria and recognized only the following
two species in the West Indies: F. scandens DC. (Cuba and Jamaica) and F. stellata (Vell.) Fourn. (Trinidad).
A current annotation in TROPICOS suggests that the type of C. crispiflora Sw.—the Plumier figure—may
be Prestonia agglutinata (Jacq) Woodson (= Allotoonia agglutinata Jacq.) J.F. Morales & J.K. Williams). I am
unfamiliar with this latter taxon, but a comparison of the Plumier figure to that of Allotoonia agglutinata
(syn. Echites agglutinata) as illustrated in Acevedo-Rodríguez (2005), shows differences in the corolla lobes
(linear-lanceolate in Acevedo-Rodríguez (2005) vs. suborbicular in the Plumier figure).
Fischeria crispiflora (Sw.) Schltr. in Urban, Symb. Antill. 1(2):268. 1899, nom. illeg.
Notes: A superfluous combination; see F. crispiflora (Sw.) K. Schum.

See Cynanchum crispiflorum Sw.
Gonolobus ottonis C. Koch & Bouche, Ind. Sem. Hort. Berol. 13. 1855.
Protologue: unknown.
Type: unknown.
Notes: Sometimes cited as Gonolobus ottonis Walp. (Ann. Bot. Syst. 5:502. 1859.). However, Walpers (1859)
clearly cited G. ottonis C. Koch & Bouche and should not be considered author of a homonym. Walpers
(1859) repeated Koch and Bouche’s citation: “Ex insula Cuba reportavit Otto. However, Schlechter (1899)
thought that the specimen collected by Otto (apparently formerly at B) was from Caracas, Venezuela, not
from Cuba. The location of the type is unknown.
Gonolobus oxyanthus Turcz., Bull. Soc. Imp. Naturalistes Moscou 25(2):318. 1852.
Protologue: "Venezuela, Funck 2," fide TROPICOS (protologue n.v.).
Type: Venezuela, 1845-1852, Funk 2 (G, n.v.; P, nv.) fide TROPICOS.
Notes: Fide Fontella & Schwarz (1981), a synonym of Gonolobus rostratus (Vahl) R.Br. ex Schult. (Systema
Vegetabilium 6:61. 1820). TROPICOS (23 Aug 2006) cited Funk 2 (Venezuela) as the type, but a copy of the
protologue could not be located. Specimens were not found on either of two visits to P.
Gonolobus virescens Desv. ex Ham., Prodr. Pl. Ind. Occid. 32. 1825.
Protologue: “Herb. Prof. Desvaux, Jamaica. (S. v.),” loc. not cited.
Type: Jamaica,” Herb. Desvaux (HOLOTYPE: P!).
Notes: Rendle (1936) considered G. virescens Desv. a species incerta. Schlechter (1899) noted that there was
likely a locality mix-up between G. stapelioides and G. virescens, and that the latter was likely collected from

Tobago and not Jamaica (see discussion under G. stapelioides above). The morphology of the flowers of Des-
vaux s.n. (P) places it in Marsdenieae Benth., rather than Gonolobinae.
Lachnostoma ovatum Turcz., Bull. Soc. Imp. Naturalistes Moscou 25(2):318. 1852.
Protologue: unknown.
Type: unknown.
Notes: Cited as L. ovata and as a synonym for Matelea ovatifolia (Griseb.) Woodson by Alain (1957). Neither
protologue, nor type could be located.

The tribe Stipeae Dumort. are enparan, cool-season (C; 3) E that ae] occupy somewhat moist to
predoptinan dry open grass} teppe pt Antarctica. Worldwide
the Stipeae consist of a minimum of 21 Bened and 524—604 species, denen: on how Ásian taxa are
recognized (Soreng & Davis 2005). In the New World there are 279 species of Stipeae (Soreng et al. 2008);
of these, 222 (79.696) are found in South America. Thirteen genera are indigenous, and nine are endemic
to the New World. The Stipeae s.s. (excluding elements of Phaenospermateae Renvoize & Clayton, and
subtribes Ampelodesminae Connert and Duthieinae Pilg. ex Potztal) are characterized by having single-
flowered spikelets with terminally-awned lemmas where the awn is the result of the fusion between the
central and two lateral vascular traces, simple starch grains, florets with two or three linear lodicules, and
small-sized chromosomes with a base number of x = 10-12. The Stipeae are placed in subfamily Pooideae
(GPWG 2001). Within the Pooideae they are an 'early diverging lineage that arose after the separations of
the Brachyelytreae Ohwi, and Lygeeae J. Presl plus Nardeae W.DJ. Koch (Davis & Soreng 2007).
Historically, delimitation of genera within the American Stipeae was based on a broad concept of the
genus Stipa L. Hitchcock (1935, 1951) accepted three genera in North America: Oryzopsis Michx., Piptocha-
etium J. Presl, and Stipa. In South American Stipeae, Spegazzini (1901) recognized only Aciachne Benth.,
n 1 ' sal ni yl geny CA e Sti J , Pappostipa 167
i
Oryzopsis, and Stipa. In the second part of the 20th century, Stipeae taxonomy was characterized by the
consecutive resurrection of previously described genera or emendation of taxa considered by Spegazzini
(1901, 1925) as subgenera of Stipa. Nassella (Trin.) E. Desv. was restored to generic status by Parodi (1947)
and significantly expanded, and thus became the most species rich genus among American Stipeae (Bark-
worth 1990; Barkworth & Torres 2001). In considering the distribution of morphological features among
stipoid grasses and lemma epidermal features (Thomasson 1978, 1980, 1981, 1982), Barkworth and Everett
(1987) suggested that Stipa includes only Eurasian species: Hence the name Stipa should not be used for
any American species. In subsequent major rearrangements of the American Stipeae, five species were
transferred to Hesperostipa (M.K. Elias) Barkworth. Thirty-seven other American species formerly placed in
Stipa or Oryzopsis were shown to share some morphological features with the Eurasian representatives of
Achnatherum P. Beauv.; they were transferred to the latter genus (Barkworth 1993). Stipa subg. Anatherostipa
Hack. ex Kuntze (Kuntze 1898; Spegazzini 1901, 1925), including the Obtusae group of Parodi (1946), was
recently established at the generic rank by Peñailillo (1996), currently with 11 species (Soreng et al. 2003).
Nassella now includes 115 and Piptochaetium 35 species, respectively (Soreng et al. 2003).
The genus Jarava Ruiz et Pav. was resurrected by Rojas (1997), in the sense of Stipa subg. Jarava (Ruiz
et Pav.) Trin. & Rupr. (Caro & Sánchez 1973), and significantly expanded by Peñailillo (2002, 2003) to 55
species by inclusion of Stipa subg. Pappostipa Speg. and S. subg. Ptilostipa. Speg. The expansion of Jarava
effectively completed the removal of all remaining accepted eae Oe New wens pede im the Reus
Stipa, as anticipated by Barkworth and Everett (1987). However, Sti
that such a broadly circumscribed Jarava was probably Hopi lert, and Arriaga p Barkworth (2006)
began to revise it by transferring five Jarava s.l. species to a new genus, Amelichloa Arriaga & Barkworth.
Parodi (1960) recognized two main morphological leaf types in Spegazzini’s Stipa subg. Pappostipa,
represented by Stipa speciosa and S. humilis (Arriaga 1983). The first type (leaf anatomical “type I” of Arriaga
1983) encompassed species with stiff, thick, and usually pungent leaves. The second type (“type II” of Ar-
riaga 1983) covere d species with comparatively thin, slender, and non-pungent leaves. Later, Parodi (1960),
followed by Roig (1964) and Nicora and Rúgolo de Agrasar (1978), noted that species with the former type
had brownish-red basal sheaths and species with the latter type had pale basal sheaths.
There have been several attempts to infer phylogenetic relationships among stipoid genera based on
morphological evidence (Tzvelev 1977; Barkworth & Everett 1987; Thomasson 1978, 1985) and preliminary
molecular analyses (Jacobs et al. 2000, 2007; Cialdella et al. 2007). The origins of Hesperostipa, Jarava s.s.,
Piptochaetium, and Stipa s.s. have been reported as monophyletic (Jacobs et al. 2000, 2007; Cialdella et al.
2007), but the overall phylogeny of the American Stipeae remains poorly bin E and EOD)
Our preliminary study of the Stipeae phylogeny based on ITS sequence data ko et al. 2007)
revealed a deep separation between a Euro-Mediterranean clade, EE Sia s.s., and a clade including
genera and species of East Asian, Australian, abs nM v pn In addition, Jarava (sensu Peñailillo
2003) was resolved as polyphyletic, with a clade y placed in Stipa subg. Pappostippa, clearly
independently derived from the core species of aram S.S.
The main objectives of this paper are to present a phylogenetic hypothesis for the American Stipeae
and to evaluate the monophyly of Jarava s.l. based on an analyses of plastid (matK, EE trnH-psbA
and trnL-trnF) and nuclear ribosomal ITS DNA sequences. We also discuss phological and anatomical
characters that support our phylogenetic M RAM

Sher RE? and Nardus stricta were chosen as outgroups based on the paculie of eo else
of phylogenetic relationships in Pooideae (Hilu et al. 1999; Soreng & Davis 2000; GPWG 2001; Davis &
Soreng 2007; Soreng et al. 2007). These outgroups were used to root trees in the ITS analyses of the Stipeae
(Jacobs et al. 2000; Romaschenko et al. 2007).
DNA extraction, lifi ing.—Leaf tissue was homogenized using Qiagen TissueLyser,
and DNA was isolated using a BioSprint 96 DNA Plant Kit (Qiagen, Valencia, California, USA, 2005). For
some specimens, the CTAB method (Doyle & Doyle 1987) was used.
PCR amplifications were performed in MJ Research or PE 9700 thermal cyclers. Genomic DNA was
combined with 1x reaction buffer (200 mM Tris-HCl, 500 mM NH) (Bioline Biolase Taunton, Madison,
USA) without Mg++, 2 mM MgCl,, 200 mM dNTP's, 1.5pl of Taq polymerase (Bioline Biolase Taunton,
Madison, USA), 40 pmol/ul each of forward and reverse primers.
The entire nuclear ribosomal ITS regio ified using primers ITS1, ITS2, ITS3, ITS4, ITS5 (White
et al. 1990) and ITS5A (Stanford et al. 2000) with the following thermal cycler settings: initial denaturation
step of 2 min at 94°C, followed 35 cycles at 94°C for 30 s, 50-55ºC for 30 s, 72°C for 1 min 30 s, and a final
extension of 10 min at 72?C.
Four chloroplast DNA regions were sequenced: trnK-matK, matK, trnH°V°-psbA, and irnL5'-trnF.
The 5'-end of trnK-matK and 5'- matK were amplified separately. The 5'trnK-matK readily amplified using
the forward primer trnK3914F (Johnson & Soltis 1995) and newly designed reverse primer trnK6605R
(5'-CGAATGATGATACATAGTGC-3) positioned close to the end of the 5'-trnK-matK intron. The reverse
complement (i.e. forward version) of the latter primer (trnK660SF; 5'-GCACTATGTATCATC ATICG-3) and
the reverse complement of a slightly modified matK1412F primer (Johnson & Soltis 1995; i.e., matK14125R
3- CTGATACATAAGAGTTRTAT-3) were used to amplify hos poe: of Me E end of matK. The DCH ze
lified with primers trnHSUS (Tate & Simpso d psbA (Sang etal. 1997). The
trnL- trnF Econ (which included a portion of 3'-trnL intron, the 3- trnL exon, and the trnL-trnF intergenic
spacer) was amplified using primers 5'trnLU^^(f) and trnFS44(c) [Taberlet et al. 1991]. The amplification
parameters for all chloroplast regions were: 94°C, 2 min; 35 cycles of 94°C for 45 s, 58-62°C for 45 s, 72°C
for 1 min 30 s; 72°C for 10 min. PCR products were cleaned with ExoSAP-IT (USB, Cleveland, Ohio, USA).
DNA sequencing was performed with BigDye Terminator Cycle Sequencing v.3.1 (PE Applied Biosystems,
Foster City, CA, USA) according to the following parameters: 80°C, 5 min; 25 or 30 cycles of 95°C for 10 s,
50°C for 5 s and 60°C for 4 min. Sequenced products were analyzed on an ABI PRISM 3730 DNA Analyzer
7900HT (ABD.
Sequences were aligned manually using BioEdit v.7.0.5.3 (Hall 1999) and then by eye. All sequences
were submitted to GenBank (http://ww bi.nlm.nih.gov); voucher information, and GenBank accession
numbers are provided in Table 1. Even though some indels, especially in chloroplast regions, seemed to be
very specific for phylogenetic groups, they were not re-coded for this analysis and were excluded along with
ambiguously aligned regions. The following gene regions were excluded: trnK-matK with four regions of
2-25 bp in length; trnH-psbA with 10 regions of 1-4 (22) bp in length; trnL-trnF with 31 regions from 1-6
(20) bp; and ITS with 15 regions 1-4 (-22) bp. No regions were excluded from matK. All gaps were treated
as missing data. Parsimony analysis was performed using PAUP v. 4.0b10 (Swofford 2000) and PAUPRat
v.1b (Sikes & Lewis 2001), which implements the Parsimony Ratchet of Nixon (1999). Parsimony searches
were carried out for individual E combinen P and combined plastid and nuclear regions. In
searching for the optimal tree, the | d and tree bisection-reconnection (TBR)

was chosen as a branch swapping algorithm. Character states specified as unordered and unweighted.
PAUPRat searches were set for generating 1001 most parsimonious trees. Because PAUPRat finds the most
parsimonious tree in each iteration, a set of 1001 iterations is recommended by program developers as suf-
ficient to derive a consensus tree. All of the most parsi in our analyses were of the same length.
These data sets were used to yield the oa consensus trees.
Bayesian posterior probabilities were ci Bu Mae ds v.3.01 (Huelsenbeck & Ronquist 2001;
Ronquist et al. 2005) and the best ilabl tit was selected using MrModeltest 1.1b (Nylander
2002). The symmetrical model (SYM+I+G; Zharkikh 1994) with gamma-distributed rate variation across
sites was selected by hierarchical likelihood ratio tests (hLRT) and Akaike information criterion. Bayesian
analysis was initiated with random starti 1 was initially run for 1 x 10° generations with sampling
frequency of the chains set to every 100% iteration. If this number of generations was not sufficient for the
Markov chains to reach stasis, additional generations were invoked. The standard deviation value of the
split frequencies below 0.01 indicates that Markov chains reached their stasis (Ronquist et al. 2005). The
number of generations needed to complete the analysis varied from 1 x 10º for individual DNA regions to
4 x 10º in analysis of the combined data. Branches with posterior probabilities (PP) >0.95 were considered
statistically significant. For additional information about the stability of phylogenetic groups the branch
frequency or parsimony frequency (BF) value was used. The BF value indicates how often a branch appeared
in the analysis, i.e., when this value was 100% it means the node appeared unchanged in all iterations (i.e.,
strict consensus).
Bootstrap has a long history of being used as a standard measure when estimating phylogeny and we
have included bootstrap analysis. Felsenstein (1985) states, “Bootstrapping provides us with a confidence
interval within which is contained not the true phylogeny, but the phylogeny that would be estimated on
repeated sampling of many characters from the underlying pool of characters.” We agree with Felsenstein
that bootstrap values are measures of repeatability rather than measures of accuracy (see Soltis & Soltis
2003). Regardless of interpretation, bootstrap values are affected by the number of characters supporting
the clade of interest and the data set as a whole (Soltis & Soltis 2003). For a dataset with no conflict among
characters, at least three characters are needed to provide 95% support (Felsenstein 1985). With real data a
greater number of characters may be needed to achieve 95% support (Soltis & Soltis 2003). Thus bootstrap
tends to be overly conservative, often underestimating a well-supported clade (Sanderson & Wojciechowski
2000). Bootstrap (BS) values were calculated using PAUP v. 4.0b10 (Swofford 2000) from 10 x 106 fast-
heuristic bootstrap replicates with random addition sequence. Sequence divergence was calculated based
on the uncorrected “p” distance measure included in Neighbor-joining search settings.

Scanning electron microscopy.—Lemma ultra st was studied using dry mature seeds sampled from
herbarium of the following species used in the phylogenetic analysis: Jarava chrysophylla, Jarava speciosa,
Jarava nicorae, Jarava pseudoichu, Jarava plumosula, and Amelichloa caudata. Wax from the seed surface was
removed by soaking the seeds in xylol solution for six to eight hours. After soaking, seeds were mounted on
scanning electron microscopy sample tables. Mounted samples were covered with gold in the vacuum spray
gun (JII-4X, Japan). The ultra structure of the lemma was studied using scanning electron microscope Jeol
(J5M35C, Japan) at varying magnifications.
Light microscopy.—Cross-sections of leaf blades were prepared with the use of a rotary microtome. Intact
leaf blades of Jarava barrancaensis, Jarava speciosa var. major, and Jarava chrysophylla from herbarium speci-
mens were rehydrated for 10-12 min in distilled water at 100 °C. For studies of the sclerenchyma tissue,
the cross-sections were stained with safranin.
RESULTS
Amplification of the trnK intron was significantly improved when the 5'-end of the intron and the maturase
K gene were amplified separately. This enabled us to optimize our protocol for routine amplification of all
chloroplast regions, even when old herbarium material was used. With this approach, PCR reactions were

up to 6096 more successful than when the traditional intron primers were used (i.e,, trnK3914F-2R). Conse-
quently, the trnK! intron had the highest rate of amplification (92.6%) compared to the non-coding regions
trnH-psbA (91.496) and trnL-trnF (8996), which are traditionally considered to be the most easily amplified
regions of the chloroplast genome (e.g., Kress et al. 2005). The matK gene had a lower rate of amplification
(85.296); lack of matK sequence data for a subset of taxa probably affected branch support in the combined
chloroplast analysis. For the most of the silica preserved samples or recently collected herbarium specimens
the entire ITS region was easily amplified (10096). A few specimens that lack several chloroplast regions
were not included in the chloroplast analysis but we did include them in the combined analysis based on
ITS and partial plastid sequences. A small subset of samples with two or more missing chloroplast regions
was included in the combined analysis (see Table 1 for details). The plastid data set is missing 11.4% and
the combined analysis is missing 996, mostly due to unsequenced plastid regions for some samples. There
is no missing ITS data.
Analyses of DNA sequences.—The general characteristics of the DNA regions used to infer phylogeny in
our data set are detailed in Table 2. The greatest number of potentially parsimony informative characters
per region was provided by the nuclear DNA ITS region.
The topologies of the trees produced by parsimony and Bayesian analyses for each of the four plastid
regions sequenced were not inconsistent with that produced by the combined plastid data. Since the sepa-
rate pane datasets d comparatively low numbers ei Ge e cds EE and low levels of
nc ombined (Fig 1). The phylog tr nH-psbA
and trnL-trnF EE were stronger than other gene regions and were eclighily better oa partly due to
their higher Ee of EE SE ds 2)
Noc derived from the trnH-psbA and trnL-trnF regions were
found in this amd se The only region that ud sae substitutions responsible for separation of the
Pappostipa clade of Jarava s.l. was the trnL-trnF region (data not shown).
The ITS tree was more than two times longer than the plastid tree and had lower CI and RI values
(Table 2). There was relatively minor topological incongruence among clades in the trees generated from
the combined plastid DNA-ITS data set (Fig. 3) and the ITS data (Fig. 2).
The monophyly of the Stipeae is well supported (BF=100, PP=0.64-1.00, BS=96-100) in all three cla-
dograms (Figs. 1-3). Several major clades were consistently resolved in all three analyses (Fig. 1-3). A clade
including Achnatherum, Amelichloa, Austrostipa, Jarava s.l., and Nassella [AAAJN] was detected in all three
analyses (Figs. 1-3). Within the AAAJN clade a primary deep split between the Pappostipa clade and the
clade of Austrostipa plus Achnatherum, Jarava (excluding the Pappostipa clade), Nassella and Amelichloa was
maintained in all three analyses (Figs. 1-3). Austrostipa (from Australia) was resolved in all three analyses
as sister to a clade of Achnatherum, Jarava (excluding the Pappostipa clade), Nassella, and Amelichloa; this
relationship received strong support only in the nuclear and combined analyses. The latter clade is denoted
in Figs. 1-3 as the Major American Clade or MAC.
Within-MAC, Achantherum was always monophyletic and the sister group of the rest of the clade. A
clade of Nassella with Amelichloa nested within it was detected in all three analyses (Figs. 1-3); this clade

statistics i.e., consistency index, retention index, and rescaled consistency index, for the combined plastid
DNA-nrDNA set was higher than for nrDNA set alone.
Early diverging clades at the base of the Stipeae included the genera Ptilagrostis (only as a polytomy in
Fig. D, Anatherostipa, and Piptochaetium. All analyses su

current level of taxon sampling (Figs. 1-3) ción of
the datasets. Analysis of the plastid data set yielded a consensus Rs with these VEHI and Hesperos-
tipa in a polytomy with a large clade including Jarava s.l., Austrostipa, Achnatherum, Nassella, and Amelichloa
[AAAJN]. Analysis of the ITS data set yielded a stepwise grade leading to Hesperostipa as sister group to
AAAJN. The analysis of the combined plastid-nuclear data set resulted in a fully resolved and a moderately
well supported resolved basal clade of ur E as sister group to Anatherostipa and Piptochaetium (Fig. 3;
BF=71, PP=0.93), and Hesperostipa ter group to AAAJN (Fig. 3; BF=100, PP=1.00, BS=100). Henceforth,
for ease of discussion, we Exil the set of Anatherostipa, Piptochaetium and Ptilagrostis the "basal lineages"
(BL in EIS 1-3). The position of these the basal lineages with respect to the core of the tree needs further
examinati n, particularly including Old World genera, and is not the focus of the present study. Both of the
Piptochaetium groups (Cialdella et al. 2007), Piptochaetium sect. Podopogon (Raf.) Parodi (P. ruprechtianum)
and Piptochaetium sect. Piptochaetium (P. panicoides) are represented in the analysis. In all topologies, the
Piptochaetium clade had high statistical support (BF=100, PP=0.95-1.00, BS=59-96; Figs. 1-3).
Representatives of the two extant geographical lineages of Ptilagrostis chosen for analysis were P. mon-
gholica from Asia and P. porteri from the Americas. These species formed a consistent and well supported
clade (BF=100, PP=1.00, BS=95) on the ITS tree (Fig. 2) and the combined tree (Fig. 3; BF=100, PP-1.00,
BS=97). A phylogenetic relationship between these two species was resolved as a polytomy in the consensus
tree from the plastid analysis (Fig. 1).
There are two clades adjacent to the basal lineages. One comprises the representatives of the genus
Hesperostipa in a clade in all three trees (BF=100, PP=0.99-1.00, BS=99-100; Figs. 1-3). A second clade
contains AAAJN members showing deep split (polyphyly) in the genus Jarava: Stipa subg. Pappostipa (Pap-
postipa clade) of Spegazzini (1901) elements of Jarava are separated from Jarava s.s. by sequentially diverging
clades of Austrostipa and Achnatherum (BF=99-100; PP=0.63, «0.50, 0.99; BS=99, «50, 99; respectively in
Figs. 1-3). In combined analyses as well lear DNA ITS sequence analysis, the Pappostipa clade
was well supported (BF=100, PP=0.95-1. ER BS- Se 99; Figs. 2 & 3).
4 was sister group to MAC. These clades had high statistical
support (BF=100; PP=0.68-1.00; BS=90, «50, 80; respectively in Figs. 1-3) and their relationship as sister
clades was consistent.

Comparative morphology.—We evaluated a series of morphological and anatomical characters including:
awn indumentum, form of the callus, lemma epidermis, and anatomy of the leaf blade in transverse section
that differ among the DODGE adn of Jarava s.l. Nearly all samples of Jarava s.l. listed in Table 1
were surveyed and re] examples are given in Fig. 4. In addition, features of Amelichloa have also
been evaluated.
1 e J. A) 1.1 4
Callus.—In the Pappostipa clade (Fig. 4A-C) the callus i te to acuminate
the callus base plane and floret axis is low; callus base is lanceolate; seel See is marginiortit with
proximal borders near one another, not fused nor thin, leaving an open foveola (literally, “small depression
or scar"; the term used to name the section of conducting bundle at the base of the callus, but not only its
open ventral part as it was for species resolved here in the Pappostipa clade by Roig 1964); distal, flat prow
of the peripheral ring is not developed or is moderately developed. The foveola is fusiform or lanceolate,
usually the same shape as the peripheral ring.
In the Jarava ichu group (Fig. 4D) the call hort, truncate, blunt to acute; the angle between the callus
base plane and floret axis is higher CS in Pappostipa clade; callus base is obovate or ovate, rarely orbicular
or lanceolate; peripheral ring is marginiform to flat, proximal borders not near each other, thinned and not
fused, leaving the foveola open; distal, flat prow of the peripheral ring is not developed, inconspicuous or
is slightly conspicuous. The foveola is obovate, ovate or orbicular, rarely lanceolate, and usually the same
shape as the peripheral ring.
In Jarava media, J. plumosula, and J. polyclada, (Fig. 4E) the
the callus base plane and floret axis is high; callus base is ovate or acuminate, eege to the M MEM long
but obtuse point; peripheral ring is flat or slightly marginiform, proximal borders joined, usually fused and
not thinned, closing the foveola; distal, flat prow of the peripheral ring is well developed, characteristically
fused at the base. The foveola is oval or orbicular and does not follow the shape of peripheral ring.
In Amelichloa caudata and A. cladestina (Fig. 4F) the callus is short, blunt; the angle between the cal-
lus pare plane and floret axis is high: callus base is obovate or oblong; peripheral ring is conspicuously
, proximal borders not near each other, thinned, leaving the foveola open; distal, flat prow of
the pesca ring is not developed or is inconspicuous. The foveola is oval or oblong ellipsoid and usually
follows the shape of the peripheral ring.

Lemma epidermis.—In species of the EE clade (Fig. 4G) the epidermal fundamental cells regularly
alternate with silica cells and are all apy tely the same dd or shorter than the silica cells; end walls
are straight or slightly uneven, sidewalls slightly si s are oval to oblong rectangular, slightly
unequal. In the Jarava s.s. group (Fig. 4H) the — fundamental cells regularly alternate with silica
cells and are considerably shorter than the silica cells (designated here as *maize" pattern); end walls are

Leaf blade transection.— Basal leaf blade cross-sections from Jarava barrancaensis, J. speciosa var. major,
and J. chrysophylla are shown in Fig. 4J-L, and represent anatomical forms in the Pappostipa clade. We
found two distinct types of leaf morphology and anatomy as detected by Arriaga (1983) that correspond
with the two subclades P and C in our trees (Figs. 2&3). The P clade has type I leaf blade anatomy (incl.
Jarava barrancaensis, J. hieronymusii, J. nicorae, J. patagonica, J. speciosa var. major, J. speciosa var. speciosa, and
J. vaginata) with stiff, relatively thick usually pungent leaf apices, adaxial ribs well developed, separated by
deep furrows; primary veins (vascular bundles) are numerous (5 or 6), often adaxially and abaxially con-
nected by sclerenchyma girders (rarely by Geer EE girders; Fig. 4J); tertiary veins are often
abaxially connected by scl | girders; bulliform t at the bottom of all f ; abaxial
sclerenchyma is MM ACE dal sitet da is rd (Fig. 4K).
The C clade (Figs. 2&3) has type II leaf blade anatomy (incl. Jarava atacamensis, J. frigida, J. humilis, and
J. ibarii) with slender, usually non-pungent leaf apices, adaxial ribs not well developed separated by shallow
furrows; primary veins not numerous (1-3, rarely to 4), often only abaxially connected by sclerenchyma
girders (rarely adaxially connected at the midrib); tertiary veins are AMI not depen by sclerenchyma;
bulliform cells are present only close to the midrib; abaxial ; adaxial scleren-

TAXONOMY
The phyl ic inf tion provided by our DNA analyses coupled with significant morphological differ-
ences n the Jarava s.l. clades detected, forces us to recognize the Pappostipa clade as an independently
derived monophyletic genus if we are to maintain the monophyletic status of the other genera currently
recognized in the AAAJN clade. Here we propose combinations in the new genus Pappostipa for all 14 spe-
cies resolved in this clade in our DNA analyses, and Stipa speciosa f. major which is raised to the rank of
species in Pappostipa. Eight additional species are transferred to Pappostipa that were formerly included in
Stipa subg. Pappostipa by Parodi (1960) and or Jarava s.l. by Peñalillo (2002, 2003), based on their shared
morphology with the DNA tested set of species. All currently accepted infraspecific taxa (Peñalillo 2003)
in these 23 species are also transferred to Pappostipa. Leaf anatomy types described by Parodi (1960) and
Arriaga (1983) correlated with the two Pappostipa subclades (P & C) detected in our DNA analysis. Further
review of Pappostipa leaf blade and sheath morphology after our DNA analyses (based on Roig 1964, Nicora
Sr Rúgolo de Agrasar 1978, and pers. obs.), continue to support this correlation. Therefore we conclude that
Pappostipa can be divided into two morphologically distinct sections of 14 (P. sect. Pappostipa) and nine (P.
sect. Chrysovaginatae) species.

DISCUSSION
Basal lineages.—1n order to focus on Jarava s.l. and the major American lineages of the Stipeae in the
present paper we have excluded all except representatives of two extra-American lineages (i.e., one Asian
Ptilagrostis and five species of the Australian genus Austrostipa) of Stipeae from our DNA analyses. Several
small American genera were excluded from the present paper as they were not considered to be pertinent
to the subjects of the present paper (see Methods), but they will be treated in subsequent publications. The
phylogenetic patterns we detected with the present data are consistent with those detected with our larger

story in the full dataset, not too much should ie radi into e placement of Austrostipa by itself as sister to
the Major American Clade (MAC) in which, Achnatherum, Jarava s.s., Nassella, and Amelichloa are included.
Nevertheless, some things can be said about the basal lineages as resolved here.
The early diverging or sister group position of the basal lineages (here Piptochaetium, Ptilagrostis, and
Anatherostipa) in relation to Achnatherum, Amelichloa, Austrostipa, Jarava s.l., and Nassella [AAAJN] has never
been indicated in previous reconstructions of the phylogeny of the Stipeae. An early diverging position of
Piptochaetium (as a part of a complex of North American Piptatherum/Oryzopsis plus Piptochaetium) within
Stipeae was reported by Jacobs et al. (2000) based on ITS sequence analysis. However, the authors assigned
more weight to morphological similarities of this group with Nassella and consequently the early diverging
position of Piptochaetium was thought to be an artifact. The early diverging position of Piptochaetium also was
not recognized when a larger data set was used (Jacobs et al. 2007). Various morphological characters, such
as: short, obovate floret, eccentric straight hairless awns, development of a crown, bulbous-based hairs on
the apex of the lemma, silicified walls of fundamental cells ofthe lemma epidermis, and type of epiblast has
suggested a close relationship between Piptochaetium and Nassella Thomasson 1978; Barkworth & Everett
1987; Barkworth 1990, 1993; Jacobs et al. 2000; Barkworth & Torres 2001; Cialdella & Giussani 2002).
In contrast to these conclusions, our data support a monophyletic origin of Piptochaetium near the base of
the American Stipeae, thereby rendering Nassella and Piptochaetium as distant relatives. An independent
origin of the above suite of characters in Piptochaetium, well removed from Nassella, is in agreement with
the latest revision of Piptochaetium based on phylogenetic analysis of plastid trnL-F and rpl16 sequences and
morphological characters (Cialdella et al. 2007).
All three genera of our “basal lineages” set (i.e.; Piptochaetium, Ptilagrostis, and Anatherostipa) have a
"saw" like pattern on the lemma fundamental cells, where the side walls are usually much longer than end
walls, strictly sinuate, lobate or dentate, and fundamental cells do not regularly Ee We SE Ree
(Barkworth 1983; Barkworth & Everett 1987). This lemma epidermal pattern is ev idently the p
condition in Stipeae and can be assumed to be an unspecialized characteristic within the Pooideae since no
other pattern has been ii SO i in Méien to EE fossil stipoid grasses (Thomasson 1978, 1980, 1981,
1982, 1985). There a ¡fiable fossils from the Oligocene of the Stipeae called Berriochloa
M.K. Elias with a “saw” like pattes in Xd lemma epidermis. Some early Pliocene fossils referred to Nassella
(Thomasson 1978) have short fundamental cells but still have sinuate sidewalls and end walls like the basal
lineages identified here, such as Piptochaetium but unlike extant species of Nassella.
Our molecular analyses indicate that Ptilagrostis and Achnatherum are also phylogenetically distant.
This conclusion is further supported with micromorphological data, as the two genera have different lemma
epidermal patterns (Barkworth 1983; Barkworth & Everett 1987). Based on the topology of our trees (Figs.
1-3), the polarization of the epidermal characters from Achnatherum (as a conditionally ancient state) to
Ptilagrostis (as a conditionally derived state), as proposed Tzvelev (1977) and Barkworth and Everett (1987),
is not parsimonious. We deduce that Ptilagrostis has the ancestral conditions for epidermal characters.
The monophyly of the genus Anatherostipa is supported by all our molecular analyses (Figs. 1-3) and
Ptilagrostis appears to be the sister group of Anatherostipa plus Piptochaetium (Figs. 2 S » Rr dees of
Anatherostipa other than the “saw” like lemma epidermal pattern, are the short glumes relative to the lemt
long (often prow-tipped) paleas, and lemmas occasionally with small teeth or lees at the apices (! (Matthei
1965; Barkworth & Everett 1987). These lemma apex characteristics were considered by Tzvelev (1977)
to be an ancestral or plesiomorphic state in the Stipeae. Species of Anatherostipa share the lemma surface
pattern and apical teeth character with Ptilagrostis.
The great variation in morphological forms, particularly the diversity of modifications in shape and
size of floret and awn indumentum with apparent adaptive functions, within the basal lineages and MÁC,
is a primary reason why these separate groups were difficult to detect based solely on the study of mor-

in phylogenetically distant groups of Stipeae. Desp eto
or herbivoric adaptations, in addition to sharing the unc (ane E pattern, the basal lineages
among themselves have relatively low levels of divergence in DNA sequences. The divergence value for the
most variable ITS region was 17.696 for the out-group to ingroup taxa and is only 2.996 for the basal lin-
eages. This latter value is not significantly higher than for Nassella where it was 2.696. Relatively high (up
to 4%) sequence divergence values between the basal lineages and the Hesperostipa clade indicates a greater
evolutionary distance between them even though they share the “saw” like lemma pattern. The “saw” like
lemma epidermal pattern found in the basal lineages is also known to occur in Hesperostipa (Thomasson
1978, 1980, 1982, 1985; Barkworth 1990; Cialdella & Giussani 2002). Hesperostipa also shares a long and
prow-tipped palea with Anatherostipa (Barkworth & Everett 1987). Hesperostipa is a small phylogenetically
and geographically isolated genus of the North American Stipeae.
Pappostipa.—The phylogenetic history of the Pappostipa clade supported by our molecular analysis of
plastid DNA and nrDNA sequences (Figs. 1-3) provides evidence that Jarava s.l. is polyphyletic and the
circumscription of the genus proposed by Peñailillo (2002) cannot be maintained. Consequently, we el-
evated all of Spegazzini's Stipa sect. Pappostipa to generic status based on corroborating morphological and
anatomical evidence of differences with the remainder of Jarava. The phylogenetic resolution of Austrostipa
and Achnatherum clades between Pappostipa clade and more highly derived Jarava s.s. clade clearly indicates
that Pappostipa and Jarava s.s. do not share a most recent common ancestor. Pappostipa appears to be inde-
pendently derived from the group we have called the Major American Clade (MAC). MAC is comprised of
related genera that are geographically ca to Due ro dd vun Jarava s.s. and Nassella constituting
the principal part of the clade. Recent phyl on plastid DNA for the South
American Stipeae (Cialdella et al. 2007) ee the affinities of Pappostipa with the basal lineages since
Pappostipa vaginata was inferred to be the sister group of an Aciachne-Anatherostipa-Piptochaetium clade. The
phylogenetic position of Pappostipa speciosa (reported as “Achnatherum speciosum”) within the Achnatherum
clade based on ITS sequences by Jacobs et al. idi zn is pone oy our more extensive analysis.
Some key morphological features of the Pap; itional characteristics leading to
the more advanced states found in MAC, or to analogous states of characteristics independently derived in
other genera. Unigeniculate awns, straight and long-hairy columns, and usually straight glabrous bristles
are the principal diagnostic characters for Pappostipa (Spegazzini 1901). The same suite of morphological
features of the awn is developed in central Asian Stipa sect. Pseudoptilagrostis Tzvel. (Tzvelev 1977) and two
Mediterranean genera, Celtica F.M. Vázquez & Barkworth and Macrochloa Kunth (Vázquez & Barkworth
2004). Among awn characteristics, Ptilagrostis differs from Pappostipa by having twice geniculate awns, and
Macrochloa ditfers from Pappostipa by having falcate rather than straight bristles. The callus of Pappostipa is
narrowly acute to acuminate with a characteristic lanceolate or linear-lanceolate form with a basally open
foveola that follows the shape of the peripheral ring a O However, a similar structure is known in
Stipa subsessiliflora (Rupr.) Roshev. and Stipa sect. P tis (Freitag 1985; Barkworth & Everett 1987.
After complete removal of the cuticle the walls of the leming epidermal cells appear to be sinuate in Pap-
postipa (Fig. 4G) and not lobate. This type of lemma epidermal wall can be considered transitional between
the “saw” like pattern found in Hesperostipa and other basal lineage genera (Fig. 4G) and the pattern found
in MAC. However, the moderate shortening of the fundamental d e their TRAE alternating pattern
with equilateral silica cells (*maize" like pattern) enables us to l f Pappostipa with other
achnatheroid type species rather than with the pattern encountered in the basal lineages.
Our ITS analysis and combined plastid DNA and nrDNA analyses (Figs. 2&3) divides Pappostipa into
two clades that are correlated with anatomical types 1 & II of Arriaga (1983). These lineages are here named
as Papposti Pa ipa and P. sect. Chysovaginatae. Based on our molecular anal 1 by possessing
a Bue of teca and Tea morphological characteristics we placed Pappostipa barrancaensis, P. braun-

lealii, P. speciosa, P. vaginata, and P. vatroensis in P. sect. Pappostipa; and include P. ameghinoi, P. atacamensis,
P. chrysophylla, P. chubutensis, P. frigida, P. humilis, P. ibarii, and P. nana in P. sect. Chysovaginatae. Within P.
sect. Pappostipa we also recognize an informal “long-bristle” group that includes P. barrancancaensis, P. major,
P. malahuensis, and P. vatroensis. These four species all have long straight bristles, whereas the other spe-
cies have “short bristles.” We have recognized P. speciosa var. major as a species, P. major, based on different
chromosome number reports (2n=60 in P. major; 2n=66 in P. speciosa; Parodi 1960; Stebbins & Lóve 1941;
Covas & Bocklet 1945), distinct differences in the length of the hairs on the lemma and glumes, thickness
of the basal leaf blades, and color of the sheaths.
Austrostipa.—The monophyly of the Australian Stipeae, i.e., Austrostipa was supported in all of our sepa-
rate and combined analyses of plastid DNA and nrDNA regions (Figs 1-3). The Austrostipa clade is clearly
positioned as a sister group to the Major American Clade (MAC) composed of Achnatherum, Jarava s.s., and
Nassella (with Amelichloa nested inside). This general relationship, but with more Asian genera represented
in the clade in which Austrostipa was included, was detected by Romaschenko et al. 2007. The monophyly
of the Austrostipa was supported by Jacobs et al. (2000, 2007) based on the ITS analysis. However, the clade
was thought to be the most derived group in the Stipeae, preceded by clades or grades containing Nassella,
Jarava, and Achnatherum. It has been pointed out by Barkworth and Everett (1987) that the majority of the
Austrostipa species do not have shortened fundamental cells, which is a distinctive character in species of
Nassella and Jarava s.s. In addition, it was found that Austrostipa species typically have fundamental cells
with slightly sinuate walls that sometimes are two or three times longer than the silica cells (Jacobs &
Everett 1996). Therefore, we consider Austrostipa to be a somewhat specialized group and transitional to
the American Achnatherum. However, the nature of this lineage will be covered in more detail in a separate
paper where it will be placed in context of a World wide sample of the Stipeae.
Major American Clade.—One of the primary challenges of this study was to verify monophyly and ascer-
tain the boundaries of the largest group of American Stipeae. We call it the Major American Clade (MAC)
because it contains nearly 72% of the species in the American Stipeae. MAC appears to be monophyletic
and is a geographically distinct lineage comprised of Achnatherum (American lineage), Jarava s.s. (as a clade
or grade), Amelichloa, and Nassella. MAC has consistent statistical support (Figs. 1-3) as a lineage and ap-
pears as a sister group to Austrostipa. The detection of MAC provides a new phylogenetic hypothesis for the
evolutionary derivation of the majority of the American Stipeae.
Achnatherum.—The monophyly of the subset American species of Achnatherum sampled (4 out of 34 spe-
cies) was supported by our plastid and nuclear-derived trees (Figs. 1-3) and this Achnatherum clade was
always the sister group to the Jarava s.s. plus the Nassella-Amelichloa complex, in agreement with analyses
by Jacobs et al. (2000). Jacobs et al. (2000) suggested that Achnatherum was a close relative of Austrostipa, a
hypothesis that is also supported by our analysis. BOUM e exhibits a derived lemma epidermal
pattern (with fundamental cells that alternate with silic clear ^maize" pattern), and does not
have the “saw” like lemma epidermal pattern found in the basal lineages and Hesperostipa.
Jarava s.s-Nassella complex.—The core of MAC is the Jarava s.s. plus Nassella-Amelichloa complex. This
group contains ca. 160 species, representing ca 60% of ES American Stipeae. In all combined analyses
of plastid DNA and nrDNA this clade letic with high statistical support (Figs. 1-3).
Jacobs et al. (2000, 2007) did not detect this complex as a dale: in their ITS tree, whereas recent phyloge-
netic inferences based on plastid DNA data (Cialdella et al. 2007) are consistent with our results. However,
A coto a
topologies yielded by parsimony and Bayesian analyses were not consistent when
plastid and nuclear markers. Based on combined data of plastid DNA regions, Jarava ista was placed
in a polytomy between the Nassella-Amelichloa clade and the core of Jarava s.s. clade. Jarava s.s was resolved
as monophyletic only in combined ee of all pie markers (Fig. Sc

mental cells. These traits are most highly developed in Nassella where species are characterized by having
a “ladder” pattern of the lemma epidermal cells, designated by Barkworth (1990) as the “nasselloid type"
(short, silicified fundamental cells not alternating with silica cells, or fundamental cells and short cells that
lack silica) that are indistinguishable from each other. Another distinct feature of species with nasselloid
type lemma anatomy is the develo] t of the crown (a fleshy, ciliate formation) at the apex of the lemma.
Species of Jarava s.s. are characterized here as the “achnatheroid type,” with fundamental cells that alter-
nate with silica cells of the same form (Fig. 4H), forming a clear “maize” pattern, and with the absence of a
lemma crown. Among other achnatheroid traits common for Jarava s.s. species, but not observed in Nassella
or Amelichloa, are the protruding and/or in some cases reduced, lemma lobes.
Jarava s.s.—Based on our current set of samples, as seen in Figs. 2&3, the Jarava s.s. clade consists of two
distinct groups: 1) Jarava ichu group; and 2) J. plumosula group. In the ITS analysis, the Jarava s.s. clade was
resolved to be polyphyletic, with three species constituting J. plumosula group forming a clade that is sister
group to Nassella-Amelichloa (Fig. 2). In the plastid analysis (Fig. 1) only J. plumosula resolved in a polytomy
between the core of Jarava and Nassella-Amelichloa, whereas J. media and J. polyclada were placed just at the
base of the clade of Jarava s.s. (core) plus Nassella-Ameichloa complex. In the analysis of the whole molecular
dataset, all species of Jarava s.s. were weakly supported as monophyletic clade (Fig. 3). Jarava media, J. plu-
mosula, and J. polyclada all share the same habitat and a habit that includes such characters as culms havin g

Nassell luding Amelichloa. —According to the latest revision, Nassella is one of the largest genera in the
tribe (Barkworth & Torres 2001) with some e 119 spese listed as accepted by Soreng et al. (2003). A number
of subgeneric and sectional names were employed in Stipa s.l. by Spegazzini (1901, 1925) and Roig (1964) to
recognize the many forms now placed in Nassella. Despite some striking morphological differences among
the species, the majority of the species of Nassella share the same "nasselloid" pattern of the floret defined
by Barkworth (1990). This pattern includes short paleas, strongly overlapping lemma margins, presence
of crown, and a unique lemma epidermal pattern. Our nuclear and combined plastid-nuclear consensus
trees yielded a Suae i ie clade with high statistical support (Figs 2 & 3). The era structure

CONCLUSIONS
Jarava s.l. is polyphyletic and species formerly in Stipa subg. Pappostippa are removed from Jarava s.l. and
placed in the new genus Pappostipa. This new genus is phylogenetically intermediate between a group of
genera designated as the basal lineages in the American Stipeae and a set of genera designated here as the
Major American Clade. The Major American Clade includes: Achnatherum of the New World, Jarava s.s., and
Nassella (in which the genus Amelichloa is phylogenetically nested). The American basal lineages include a
clade of Anatherostipa and Piptochaetium as sister group to the Asian and American genus Ptilagrostis. Phy-
logenetically, the North American genus Hesperostipa stands between these American basal lineages and
Pappostipa plus the Major American Clade.

A PROPOSED SECTIONAL ARRANGEMENT OF PYCNANTHEMUM SPECIES
Up to the time of George Bentham's treatment of Pycnanthemum for the Prodromus of Alphonse de Candolle
(1848), two principal species-groups had MR d been recognized, first as the two genera Pycnanthemum
and Brachystemum by Michaux (1803) and tl
Tullia and Section Bracl | y Bentham (1834).
In his more elaborate treatment of 1848, Bentham formally described six sections, to be discussed below.
The much later generic monograph by Grant and Epling (1943) did not recognize formal sections, but rather
defined two principal groups, termed the Incanum Phylad, of 8 taxa, and the Virginianum Phylad, of 5 taxa
The remaining 8 species were irregularly connected to these groups in a chart (their Figure 1) displaying
a network of relationships and suggesting multiple transitional forms and gene exchange between taxa. In
their analysis, only P. californicum and P. nudum “present no transitional forms with other species.”
n our previous papers and unpublished work (Chambers 1961a, b; Chambers & Chambers 1971;
Chambers 1993) no formal sections of Pycnanthemum were recognized, but the taxa were arranged in six
informal “species groups.” These paralleled the named sections of Bentham but differed in
ts, due

194 t tani i Texas 2(
to the addition of SC Se to ee e after his publication, as well as new information gained from
tological and hy! ion studies. We went beyond Grant and Epling (1943) in not only recognizing
hee cana and “Virginianum” merde but also in organizing the outlying taxa of their relationship
network into arbitrary species groups. Our informal classification is given in Table 1, which lists the known
somatic chromosome numbers of each species (Chambers & Chambers 1971).
While Grant and Epling (1943) spoke of transitional forms between species and the possibility that
some species were themselves of hybrid origin, our later work (Chambers 1961a, b; Chambers & Chambers
1971, Chambers 1993) has defined the genus as a polyploid complex, with 9 extant diploid species (Table
1), apparent autopolyploidy in P. albescens, P. muticum, and P. tenuifolium, and 10 taxa that are limited to the
tetraploid level. The latter appear, for the most part, to be morphologically EE between known
diploids, such that an alloploid origin is strongly suggested. A pan; ploid evolution in some
species has been the development of facultative or obli y, da hologically by flow-
ers with short filaments and aborted anthers. Where Mese in sse anthered danis of P. vigina, Pp
verticillatum, and polyploid P. muticum, seed-set was normal in both bagged and un-bagged inflorescences
(Chambers 1961). Plants with aborted anthers also occur in P. tenuifolium, but although apomictic behavior
is suspected, it has not yet been checked experimentally (Chambers 1961).
Although it would be desirable to divide the genus entirely into monophyletic sections, we believe
that the reticulate nature of evolution in Pycnanthemum, involving, as it does, allopolyploidy, a polyphyletic
hybrid origin! for several widespread taxa, and the preservation of sterile hybrids via apomixis, precludes
such a classification at present. Our approach is to propose a practical infrageneric classification involving
certain arbitrary decisions about the placement of species that putatively are derived from allopolyploidy or
E £i or DDR Basic to our Meca is that each section contains one or more of the
and
y OL POly HI fallo
or apomicts). By his plat. we have EH to Opa each taxon de suspected hybrid MM into E
section contains the diploid(s) it most i This has involved a choice of emphasis on
r
certain key features, especially those of habit, leaf morphology, anid details of the inflorescence. An example
of this decision process is discussed under P. setosum, below.’
Complementing the cl l and hybridization research mentioned above have been two recent
studies using molecular approaches. The ¡Hed by Yetter (1989) examined relationships in the Virginianum
Group, using 12 enzyme systems to identify synapomorphic alleles as well as alleles unique to particular
diploid taxa. The work of Williams (2005) developed a cladogram of relationships among all but one spe-
cies of Pycnanthemum, based on sequence data from the ITS region of nuclear ribosomal DNA. (Technical
difficulties prevented the inclusion of P. setosum. Nominally no P. clinopodioides was included in her study,
but it may have been represented by a population that she classified as P. torreyi)
Our propossu or Ree eee takes account of the molecular EE from the above re-
search. It emphasi d species, using PEMEX
taxon arbitrarily in iation with che parent species that it more o The pamed sections ate their

Lectotypes are proposed, above, for the sections of Bentham con taining more than one species. As noted, the
genus Brachystemum was earlier typified by Grant and Epling (1943) with B. muticum, so Bentham’s Section
Mutica becomes superfluous. For Sect. Capitellatae, of the two species cited by Bentham we have elected
Mere S EE B. Geh (= P. virginianum) as the type rather than his B. linifolium (= P. tenuifolium),
, and Willdenow's d së tion is at variance with the type and descrip-
tion of Satureja virginiana L. ET origin of his cited synonym Thymus virginicus L. (1771).
Section Pycnanthemum is the only section containing more than one diploid species. Its members are
characterized by loose, well-branched flower clusters, both terminal and (often) in the axils of 1—4 bracte-
ate leaf pairs below this. Leaves are broad, petiolate, and often canescent on one or both sides, especially
distally on the plant. We hypothesize that this section contributed to the origin of intersectional alloploids
showing a tendency toward relatively tight but visibly branched flower clusters, for example P. beadlei, P.
floridanum, and P. pilosum, the other putative parents having tight capitula.
We dd Bentham dd in ice n EE in Sect. Aristatae, in association with its very likely
derivative P. I g of 19 IIsand 18 Is at meiosis in triploid backcross
hybrid #75, Chambers 1993). The tlie: putative parent of P. setosum, P. muticum, is in Sect. Brachystemum. An
alternative would be to create a monotypic section for P. flexuosum and leave P. setosum alone in an alloploid
Sect. Aristatae, but this goes against our plan to have each section contain at least one diploid species. Ad-
ditionally, it would create a precedent for other alloploid species like P. floridanum, P. beadlei, P. virginianum,
et al., to be seg l into monotypic sections of their own. The resemblance of P. setosum to P. flexuosum is
expressed in feat puberulence, distinct |
reduced calyx pubescence, and calyx teeth acuminate with an aristate tip up to 1 mm long. EM MES in
the northern portion of its range, P. setosum often resembles its other putative parent P. muticum in traits of
habit (general absence of leafy, sterile side-branches), leaf shape (more broadly lanceolate leaves), and up-
per bracteate leaf pair subtending the capitula (reduced, ovate, canescent, and often drooping). Besides its
morphological intermediacy, P. setosum has 2n=76, which is the sum of the diploid numbers of the putative
parental species.
Section Brachystemum, centered on oe P. muticum, also p
being included, by choice, with one of their likely diploid ancestors Á MN ri tetraploid P Mala
to P. muticum, as is suggested by the DNA data of Williams (2005), implies that the gametic number n-39
in P. floridanum must include a 20-chromosome genome derived from P. muticum. On morphological and
cytological grounds, P. floridanum's other diploid parent is probably a species with n=19 in Sect. Pycnan-
themum (as predicted by Grant and Epling 1943, p. 210, referring to their Incanum Phylad). One candidate
taxon is P. albescens, but this possible PRU ied not yet Hus tested experimentally. In a further ex-
ample, P. beadlei, another tetraploid, has traditionally been associa ically with P. montanum (they
are sympatric in the southern Appalachians). ete Williams' DNA data from nuclear ribosomal ITS
genes (2005) do not support a close phylogenetic relationship between the two. Instead, P. beadlei appears
in a clade with P. muticum and some of its other tetraploid derivates. The chromosome numbers of n=38 in
the former species and n=20 in the latter suggest that a second genome of 18 occurs in P. beadlei, perhaps
from an ancestral diploid in Sect. Pycnanthemum, where x-18 is known (although no extant species have
n-18). Artificial hybrids #12 and #15 between P. beadlei and P. muticum (Chambers 1993) showed up to 20
chromosome pairs and 18 singles at first division of meiosis in pollen-mother cells. Pycnanthemum beadlei
is therefore assigned to Sect. Brachystemum.
Section Capitellatae contains the core of the earlier Kees ee nn we view as comprising
P. tenuifolium plus hybrid derivatives of that taxon with ] ne or more t Pycnanthemum
tenuifolium is distinguished by its linear leaves, numerous small and compact floral heads, bractlets of the
heads acuminate, pungent, and arcuate basally, with stout, emergent midnerve, and a bushy habit due to
numerous vegetative branches arising from the stem nodes. In the derived tetraploid species P. virginianum,
osum, P. torreyi and P. verticillatum, the leaves are usually lanceolate, the heads somewhat looser (espe-

cially P. pilosum), the capitular bractlets less pungent (though still with a notably stout midnerve), and the
habit frequently less bushy. There is good molecular evidence that the broader leaves, less-branched habit,
and non-pungent bractlets came from the second parent of many tetraploid forms, namely P. muticum (Yet-
ter 1989; Williams 2005). From his allozyme studies, Yetter concluded: “Tetraploids traditionally labeled
Pycnanthemum virginianum and P. pilosum are thought to be allopolyploid derivatives of diploid P. muticum
and P. tenuifolium as indicated by the possession of alleles which are unique to the diploids" (1989, p. 80).
In the DNA analyses by Williams (2005), samples of the alloploid taxa P. virginianum, P. pilosum, and P.
verticillatum, of Sect. Capitellatae, were always associated in her cladograms with P. tenuifolium or P. muticum,
not with species from other sections. Additional evidence comes from the artificial diploid hybrid of P.
muticum x P. tenuifolium (#84, Chambers 1993). In the morphology of habit, leaves, and floral capitula, this
hybrid can easily be classified as P. virginianum (voucher OSC 192224). Our assignment of P. muticum to the
separate Sect. Brachystemum recognizes its involvement in other intersectional hybrids in addition to those
involving P. tenuifolium. Finally, we differ from Bentham (1848) in placing P. torreyi in the same section as
P. tenuifolium rather than with P. muticum, but this is tentative awaiting further study, since DNA evidence
suggests that P. torreyi is itself of complex, polyphyletic hybrid origin (Williams 2005).
The monotypic sections Macrocephalae, Nudae, and Californicae are not at this point implicated in the
origin of any polyploid taxa. However, intersectional hybrids have been produced artificially (Chambers
& Chambers 1971; Chambers 1993), and a natural hybrid of P. nudum x P. flexuosum has been described
(Chambers & Chambers 1971). Hybrids with mostly sterile pollen have been produced in crosses of P.
muticum x P. montanum, P. muticum x P. californicum, P. muticum x P. tenuifolium, P. flexuosum x P. nudum, P.
flexuosum x P. tenuifolium, and P. flexuosum x P. loomisii (Chambers 1993). Puzzling int liate forms will
no doubt be found in nature involving these and other species, such that species boundaries, especially at
the tetraploid level, will be blurred (Grant & Epling 1943, pp. 233—236). Even if sterile, such hybrids may
occasionally persist through seed apomixis or vegetative clonal reproduction.
Our revised sectional classification of Pycnanthemum is summarized in Table 2. A taxonomic treat-
ment of the genus is in preparation for inclusion in a future volume of Flora of North America (Flora of North
America Editorial Committee, 1993 onwards).
LECTOTYPIFICATION OF PYCNANTHEMUM VIRGINIANUM L.
There are three species named by Linnaeus in Species Plantarum (1753) that today are placed in the genus
Pycnanthemum. These are Satureja virginiana (p. 567), Nepeta virginica (p. 571), and Clinopodium incanum (p.
588). Clinopodium incanum L., now Pycnanthemum incanum (L.) Michx., is the conserved type of the genus
(Rickett & Stafleu 1960; McNeill et al. 2006). It was lectotypified with a Kalm specimen, Herb. Linn. No.
742.4, by Reveal et al. (1987, see Jarvis 2007, p. 428). We would not hazard a guess as to why Linnaeus cited
"Habitat in a parean" Hex this SD North Ámerican species
The name Sat Linnaeus 1753, p. 567) has since 1908 or before been treated in all North
American lies as ER GEN of Pycnanthemum virginianum (L.) Robins. & Fernald, a common and wide-
spread taxon in eastern North America. Its lectotypification has been uncertain, in part because some of
the pre-Linnaean polynomials cited in the original description are known to refer to the related species, P.
tenuifolium Schrad. (Epling 1929; Grant & Epling 1943; Jarvis 2007). Epling (1929) at first suggested that
P. virginianum was synonymous with P. linifolium (Willd.) Pursh, a synonym of P. tenuifolium. However, in
Grant and Epling (1943) he changed his mind, saying that Linnaeus had in his herbarium a specimen of
what we today know as P. virginianum, and because this usage “has now become well established. ...it seems
preferable not to make another change” Epling did not formally propose the Linnaean Herbarium specimen
as a lectotype, however. This specimen is Herb. Linn. 744.21. It is annotated in Linnaeus’ script "Sat[ureja] 1
virginiana” and reannotated by Smith “Sp. Pl. 1. Pycnanthemum linifolium Sm. in Rees's Cyclop.” It is filed
as sheet number 21 under the genus Thymus (Savage 1945).

nds nnus org»), and we find that it is undoubtedly a specimen of Pycnanthemum virginianum as that
plied in North America for the last 100 years. There are certain details in Linnaeus’ descrip-
tion of Satureja virgini that aptly fit this specimen but that are inappropriate for P. tenuifolium (the other
species to which “virginiana,” or the variant “virginica,” have been applied). Firstly, Linnaeus described the
leaves as "foliis lanceolatis," and in citing his earlier polynomial from Hortus Cliffortianus (Linnaeus 1737,
p. 305), he changed the “foliis linearibus acuminatis" from that work to "foliis lanceolatis acuminatis,"
E better to fit the specimen he had at hand. Secondly, this specimen has tiny stamens and clearly
of P. virginianum which is the common type found in the Atlantic Coast
states s (Chambers 19614) E non- ain stamens are well described by Linnaeus in his observation,
corolla is effoetis, ut fere posset genere proprio tradi”? This differs from
P. tenuifolium, which in this same region ieu uses sexually and has exserted stamens with functional
anthers (Chambers 19613).
Therefore, based on tl iderations, we here designate Herb. Linn. 744.21 (LINN) as the lectotype
of Satureja virginiana L., Sp. Pl. 1:567. 1753.
The difficult case of the name Nepeta virginica L., which also lacks lectotypification, is under study by
James Reveal and Charlie Jarvis (pers. comm.), and their recommendation will be published in due course.
The epithet "virginica" is not available in Pycnanthemum, due to the preexisting P. virginicum (L.) Pers. (1806)
based on Thymus virginicus L. (1771).

ABSTRACT
New Manual of Botany of the Central Rocky Mountains, by J.M. Coulter & A. Nelson (1909) is an earlier source than previously noted
for Potentilla sections Supinae, Concinnae, Subjugae, Niveae, and Multifidae. Sections Rubricaules and Leucophylleae are also established,
with the latter de Mi sect. Hippianae (Rydb.) Ertter & Reveal. The segregates from P. pensylvanica sensu lato that will be used in
a forthcoming volume of Flora of North Ámerica are briefly summarized, with Potentilla jepsonii Ertter established as a new name
for P. pensylvanica var. ovium Jepson. The distinction and identity of P. nivea var. dissecta S. Watson and P. concinna var. divisa Rydb. are
clarified. Complete lectotypifications are provided for P. litoralis Rydb., P. pensylvanica var. ovium, P. nivea var. dissecta, P. concinna var.
divisa, and P. pseudosericea Rydb.

For a forthcoming volume of Flora of North America (FNA), several nomenclatural notes, lectotypifications,
and a new name are required for Potentilla (Rosaceae); these are provided herewith.
I. Some overlooked sectional names in Potentilla
Subsequent to the publication of Potentilla sect. Hippianae (Rydb.) Ertter & Reveal (2007), a previously over-
looked source of validly published sectional names has been encountered that supersedes sect. Hippianae
and several other sections, at least as far as author attribution. In the key to Potentilla on page 255 of New
Manual of Botany of the Central Rocky Mountains (Coulter & Nelson 1909), Nelson adopts several of Rydberg's
unranked "groups" and explicitly refers to them as sections. The nomenclatural results are as follows:

II. Segregates from Potentilla pensylvanica L. sensu lato
Several entities frequently included within a broadly defined Potentilla pensylvanica L. (e.g., Hitchcock &
Cronquist 1961, McGregor 1986) will be recognized as distinct species in FNA. The critical nomenclature
is briefly summarized here, along with a new name and a lectotypification.

to accommodate all New World and some Old World plants previously placed in P multifida L., which as now circumscribed is
confined to the Old World.
III. Lectotypifications and identities of Potentilla nivea var. dissecta and P. concinna var. divisa
Potentilla nivea var. dissecta S. Watson (Proc. Amer. Acad. Arts 8:559. 1873) was described on the basis of four
syntypes: “in the Rocky Mts. of British America and Montana (368 Drummond; Douglas; Howard); and in
the Uintas, Utah (335 Watson, in part)” When Rydberg (1896b: 431) proposed "P. concinna divisa n. v." he
cited P. nivea var. dissecta “at least in part" in synonymy and included the Douglas (“Rocky Mountains”) and
Howard (*Montana") syntypes of P. nivea var. dissecta among the specimens representing his concept of P.
concinna var. divisa. The other collections cited by Rydberg were "South Dakota: Jenney. 1875; W.H. Forwood,
1887; P.A. Rydberg, nos. 672 and 673. 1892. Assiniboia: John Macoun, no. 10,468, 1895.”
Ertter, Al | p [| 4 H AS XL. A H Dus PES f | 203
Rydberg’s citation of Potentilla nivea var. dissecta in synonymy has led to the interpretation that the two
names are nomenclatural synonyms, with the epithet divisa superfluous at the varietal level (e.g., Boivin
1952, Hitchcock & Cronquist 1961). This interpretation is not supported, however, by Rydberg’s use of “in
part” and his explicit citation of some of Watson’s syntypes to the exclusion of others. Rydberg (1896b)
preceded the citation of specimens with the statement that “Dr. Watson included the three first specimens
[actually only two, those by Douglas and Howard] cited below in his P. nivea dissecta, but in every respect
they are much nearer P. concinna than P. nivea." As proof that Rydberg had two distinct entities in mind, he
(1896a: 303) had not only previously cited P. nivea var. dissecta in the synonymy of P. nivea var. quinquefolia
Rydb., but in his subsequent 1898 monograph of North American Potentilleae, he cited P. nivea var. dissecta
“in part" in the synonymy of both P. nivea var. altaica (Bunge) Rydb. and P. concinna var. divisa. The Drum-
mond and Watson syntypes of P. nivea var. dissecta, which were excluded from P. concinna var. divisa, were
instead listed among the specimens seen of P. nivea var. altaica, preceded by the statement that *Watson's
specimens agree exactly with the figure of P. altiaca [sic] in Ledebour's Illustrations, and this name is the
only one available . . ." (Rydberg 1898: 87). This dual citation was repeated in Rydberg's 1908 revision, in
which P. divisa (Rydb.) Rydb. was raised to a species and P. nipharga Rydb. replaced P. nivea var. altaica.
With the distinction of Potentilla nivea var. dissecta and P. concinna var. divisa established, lectotypifica-
tion and identity need to be determined for both entities. Rydberg's removal of the Douglas and Howard
syntypes from P. nivea var. dissecta leaves only Drummond 368 and Watson 335 as candidates. Soják has an-
notated the NY sheet of Drummond 368 as lectotype of P. nivea var. dissecta; this choice is herewith honored
and formalized. The identity of the single small, one-flowered plant is unfortunately ambiguous, with no
precise locality to aid identification; because of the subpalmate/subpinnate leaves and short columnar style
(ca 1 mm), it is tentatively identified as P. saximontana Rydb.
Of the syntypes of Potentilla concinna var. divisa, first stage lectotypification has been already been effec-
tively accomplished by Holmgren's (1997: 100) st t that Douglas's coll from the Rocky Mountains
was designated lectotype by Rydberg (N. Amer. Fl. 22:330. 1908). In that Rydberg only indicated that the
Rocky Mountains were the type locality, without actually citing a specific collection, Holmgren's statement
serves as an inadvertent lectotypification, without designating which herbarium houses the type. This would
be GH 19535, annotated as holotype by B.C. Johnston and cited as such in his (1980:165) unpublished dis-
sertation.

IV. Lectotypification of Potentilla pseudosericea Rydb.
Potentilla pseudosericea Rydb. (Mem. Dept. Bot. Columbia Coll. 2:98. 1898) was described on the basis of
three syntypes: “Nevada: Shockley, No. 592, 1888. Rocky Mountains: Nuttall; Fremont, No. 218, 1845-7.”
Ás noted by Jepson (1936: 184), Shockley 592 is actually from the White Mountains of Mono Co., California,
not Nevada. Of the two Shockley collections in GH annotated by Rydberg as "P pseudosericea n. sp.”
19583 is labeled in S. Watson's handwriting as originating in Esmeralda Co., Nevada, but with the caveat
“I think—ticket lost.” The other (GH 19584) bears an original label on which a printed “Esmeralda Co.,
W. Nevada” is supplanted by Shockley's handwritten “White Mts., Mono Co., Calif., Aug. 19, 1888, W.H.
Shockley ae ous that the Nevada citation was indeed erroneous.

cited Nuttall's manuscript name “Potentilla holosericea" in synonymy y (Rydberg 1908: 348)
specified “Rocky Mountains” as the type locality. This led B.C. Johnston to EE Nuttall's specimen at
NY as lectotype, and to annotate Shockley's “Nevada” syntype (GH 19583) as an unpublished variety of P.
pensylvanica honoring the collector. However, citation of a locality alone is insufficient for lectotypification
(Art. 37.3, Note 2, McNeill et al. 2006), so that effective lectotypification begins with W. Jepson's (1936: 184)
citation of “White Mts., Mono Co., Cal., Shockley 592” as type locality. To complete the process, GH 19583
is herewith formally designated the lectotype of P. pseudosericea.

INLRODUCLION
The representatives of the genus Vaccinium in Mexico and Central America were most recently treated by
Sleumer (1936) in a study with the deceptively modest title of “Die Arten der Gattung Vaccinium L. in Zentral-
und Südamerika." Sleumer' account actually covered the species of both the West Indies and Mexico as
well as those occurring in Central and South America. Sleumer recognized 30 species in his treatment, but
of these only 12 were known from Mexico and Central America. The present synopsis includes 27 species
from Mexico and Central America, which gives some indication of the rich yield resulting from the more
intensive field work that has taken place within the region in the past seven decades. More than half of the
Mexican and Central American species of Vaccinium have been described in the most recent three decades,
while only four species (or about 15%) were named in the first seventy-five years of the twentieth century
and nine ML (or 3396) during the nineteenth FERE
thing should be said about the generic concept adopted in the present study. The generic
limits are ge broad m inclusive like that of ene (1936) in e treatments of the West Indian, Mexican,
Central American, and South American members of the genus, as well as his survey of the genus Vaccinium
(1941) throughout its total range. In the latter paper Sleumer recognized 33 sections in the genus Vaccinium,

the senior author was exposed to a much narrower concept ol genera. In the case of vaccinoioid genera such
as Batodendron Nutt., Polycodium Raf., Herpothamnus Small, Oxycoccus Hill, Hugeria Small, and Cyanococcus
Rydb., they still appear to demark natural groups biologically meanmglul as Ja than E into
the vast diversity of the genus Vaccinium s.l. However, traditional generic were recently followed by
the authors (Luteyn & Wilbur 2005). Molecular data is sparse at SE but it is Steeg to be helptul in
sorting out some of the relationships within the tribe Vaccinieae (see Kron et al. 2002). Molecular evidence
mE po iode et al. (2002) and Powell and Kron (2003) strongly suggests that the genus Vaccinium is
pol tural; vander Kloet (2004) and Stevens et al. (2004) are also of this opinion. Kron
et "E (2002) concluded, however, that a much more thorough molecular survey must be completed before
any formal nomenclatural changes could be made. Their prognosis for Vaccinium is ominous for those who
were content with the heterogenous genus of 33 or so sections. Their molecular survey so far suggests that

“Vaccinium will need to be enlarged to include all species currently recognized in the tribe Vaccinieae, or to
be broken up" (Kron et al. 2002). Their first alternative would seem to be biologically unsound, because the
resulting "Vaccinium" would contain so many and biologically diverse groups as to be meaningless; so we
are left with the second possibility. Fortunately, Kron et al. (2002) agreed that a vast amount of work, both
morphological and molecular, needs to be done before anyone should contemplate how the diverse tribe of
several hundred species might best be redistributed. It seems certain that some of those groups to be recog-
nized may be those identified by Small and others a century or more ago. We also feel that the recognition

al. SE " ee

and Central America may prove a asa a
classification. Hence, this synopsis of the Mexican e Conil American Vaccinium is ed in the hope
that a new species-oriented base line will prove to be a useful summary of what is now known about the
genus Vaccinium in the extensive and biologically interesting region of Mexico and Central America.
The newly described taxa strongly suggest that additional collecting is still very much needed. The er-
roneous impression exists that most of the thousands of new species that are described as new each year are
present in abundance in our herbaria and that diligent general collecting is no longer needed. The species
of Vaccinium described in the past half century—and that genus clearly is not exceptional in this regard—
certainly demonstrate that all or nearly all of the newly described species are the result of material collected
since Sleumer's treatment appeared and definitely are not due to the failure of Sleumer or others to make
full use of the specimens available to them. A compelling case can be made that what is still needed is a
well-planned, intensive collecting campaign throughout much of the area.
VACCINIUM L.
Shrubs or rarely trees, often rhizomatous, sometimes arising from lignotubers (=burls). Leaves alternate
to pseudo-opposite, deciduous or briefly persistent (i.e., barely through the first unfavorable season) or
persistent and evergreen, petiolate, the blades with margin entire to (slightly) serrate, the venation pinnate
or plinerved. Inflorescences terminal or axillary, racemose, corymbose, rarely paniculate, or 1-2-flowered;
floral bract 1, subtending each pedicel; pedicels articulate or rarely continuous with calyx; bracteoles 2.
Flowers 4—5-merous, without odor; calyx synsepalous, the tube usually cylindric to globose, the lobes rarely
obsolete; corolla sympetalous, aestivation imbricate, valvate or rarely open, cylindric, urceolate, globose or
campanulate, white to pink, greenish or yellowish-green; stamens 8 or 10(-12), equal, included or exserted,
the filaments equal, distinct or weakly connate at base, equal to or longer or shorter than anthers, the con-
nectives lacking disintegration tissue, spurs on filaments present or lacking, sometimes with apparently
vestigial spurs, the anthers equal, lacking awns, the thecae surfaces smooth or papillate, the anther tubules
2, distinct or rarely shortly connate at base, dehiscing introrsely (sometimes obliquely), latrorsely or termi-
nally by pores or clefts; pollen grains in tetrahedral tetrads, lacking viscin strands; ovary inferior, 4—5 (or
falsely 8 or 10 by partial partitions)-locular; style included or rarely slightly exserted, glabrous, the stigma
small, simple or somewhat capitate. Fruit a berry, crowned by the persistent calyx lobes and capped by the
conspicuous nectariferous disc; seeds many, sometimes with mucilaginous sheath.
Vaccinium is a genus with approximately 450 species distributed in the Northern Hemisphere, Meso-
america, the West Indies, South America, E. Africa and Madagascar, Malesia, and Pacifica. Twenty-seven
species from Mexico through Panama are recognized here.

ous above, although the lamina also somewhat pustular above, all nerves raised and conspicuous beneath;
petioles ca. 1-2.5 mm long, subterete but narrowly canaliculate above, densely puberulent or pilosulose as
branchlets. Inflorescences axillary, of often leafy racemes, 3—8-flowered; rachises sharply angled, 4-34 mm
long, pubescent hlets; floral bracts leaf-like to leafy, persistent, EE acute, 5— S mm long, glabrous
to pilosulose abaxially; pedicels 5- 5—6 mm long, sometimes nodding, p
or near base, linear to oblanceolate, ca. 1.5-3 mm long, hirsutulous. Flowers 5-merous; calyx ca. 2.5-4.5 mm
long, continuous with pedicel although rarely appearing articulate as fruit matures, the tube campanulate
and x flaring distally, ca. 1-1.5 mm high and 2 mm in diam., glabrous to densely hirsutulous with white,
downwardly reflexed, delicate, white trichomes, the limb flaring above, glabrous to pilosulose, the lobes
deltoid, acute to obtuse, ca. 1-2 mm long, ciliate or puberulous to pilosulose; corolla with aestivation open,
membranaceous, unistratose, campanulate, ca. 4.7-6(-8) mm long, white, glabrous, deeply-lobed, the lobes
deltoid to oblong, acute to rounded, ca. 3-4 mm long; stamens 10, conspicuously exserted (rarely included),
ca. (4.88.5 mm long, the filaments ca. (2.733 mm long, flattened, densely hirsutulous externally and
glabrous internally, the anthers ca. (3-)5-6.5 mm long, bearing dorsally, ascending or horizontally wide-
spreading, slender, finely muricate spurs ca. 0.7-2 mm long, the thecae ca. (1.3-)2-2.5 mm long, sharply
and finely muricate, the tubules ca. (1.72)3—4.5 mm long, muricate, dehiscing by short, introrse, slightly
oblique pores that are marginally irregularly 2-4-dentate (lacinate); styles long-exserted, to 11 mm long.
Berry spherical, 5-10 mm in diam., black, sparingly to moderately pilosulose, 5-locular (2).
Distribution.—Montane forests, dry pine forests, and oak-pine forests of the Sierra Madre Oriental of
Mexico from Nuevo León and Tamaulipas, south through San Luis Potosi, Puebla, Hidalgo, and Vera Cruz,
at 1550-1785 m. Flowering: Apr-Jul; fruiting: Jun-Sep.
Vaccinium kunthianum is characterized by a calyx that is continuous with the pedicel, a corolla that is
open prior to anthesis and enlarges thereafter, by anthers conspicuously exserted beyond the corolla tube,
and by anther spurs present.
This is the only Mexican representative of the very
codium (Raf.) Rehder], a largely eastern North American taxon often Rede separate genus Polycodium
Rar e is all too easy for us to discount Rafinesquian genera out-of-hand, but this Ce genus does have
lent approbation of Nuttall (1843), one of our historically most critical and acclaimed botanists,
who Segen this group of species from Vaccinium as the genus Picrococcus Nutt. The systematics of Poly-
codium whether treated as a section, subgenus, or genus is unresolved. As many as 20 species or as few as
one species (Baker 1970) have been recognized. EEN Vander Kloet nid Ge a single species in

to synonymy. Too little material is available to bé md but the Mexican plants seem very unlike the
common V. stamineum of eastern North America. Therefore, for the present the Vaccinium kunthianum is best
treated as a distinct species. Like almost all species in Mexico and Central America much more intensive
field observation and collecting is needed.

The most ext scussion 1 Guat ] ] [the V. cespitosum - geminiflorum
complex was that of Camp (1942), based largely on his observations in western Mexico. Vander Kloet (1988)
recognized both V. cespitosum Michx. and V. geminiflorum Kunth as occurring in Mexico with V. cespitosum
represented by “one disjunct population” although his map shows three widely separated localities in west-
ern Mexico. Camp noted that the plants of V. geminiflorum from lower elevations, seldom if ever subjected
to frost, had persistent leaves while those from higher elevations had deciduous leaves. Roughly correlated
with persistence and lower elevations were more deeply grooved twigs and narrow, relatively longer leaves
at the lower elevations, while at higher li E use are more likely to be subterete and the leaves
wider. Camp concluded that because of the I tion that it would be best to maintain
the Mexican material of this complex or section EN a melena name, V. geminiflorum. He speculated that in
the Pleistocene the widespread northern V. cespitosum had had to migrate into Mexico where it encountered
V. geminiflorum and hybridized with it resulting in the great variability in the populations encountered in
the mountains of central Oaxaca. We are unable to evaluate this suggestion.
The focus of vander Kloet’s earlier publications was upon the North American representatives of the
Geng i Luteyn, S — ——— — 213
genus, but he also delt with the species of “northern Mexico.” Only Mexican species whose range was
largely in the United States and Canada were included in his account: Vaccinium cespitosum Michx. and V.
kunthianum Kunth (as V. stamineum L.). Little material was available to him for study. From vander Kloet's
keys and descriptions the following key has been extracted.

Vaccinium dissimile is characterized by its lianoid, thin-stemmed habit, short pedicels, and dark red,
campanulate corollas. This is another species of Vaccinium that rests not too comfortably with its supposed
congeners. S.F. Blake, who orginally named the species as a Vaccinium, later transfered it into the genus
Disterigma. Luteyn, currently the leading authority on the neotropical representatives of the family, has
concluded that this species should be placed in the genus Sph; Poeppig & Endlicher as shown by
the mature fruit: "The fruits of Vaccinium and Disterigma (and most eri blueberries) have a thick and
leathery pericarp that dries that way, and the seeds have normal embryos whereas in Sphyrospermum and
Themistoclesia the pericarp is very thin and papery ... and the seeds have a green embryo ...” (Luteyn 1987,
p. 126). [Note: RLW, first author of this paper, wishes to treat this species in Vaccinium; JLL, second author

Vaccinium terized by its broad, crenate-serrate leaves, long-racemose inflorescences,
its calyx articulate with the pedicel, spurred to unspurred anthers, and a falsely 10-locular berry. No other
species of Vaccinium in either Mexico or Central America has proven as baffling as V. leucanthum. As inter-
preted in this treatment, it has the greatest range of floral morphological variability of any species in the
area. On numerous occasions it was felt that a set of characters had been detected that would allow the clean
separation of a block of disconcerting variability but analysis of more specimens dashed the supposed solu-
tion. The most strikingly variable features are in leaf size and shape, number of perianth parts, and length
of the anther spurs. The variablility of spur length proved especially vexing for a priori it was felt that spur
length was of "fundamental" importance. These spurs ranged from slender, upwardly arching, long, horn-
like appendages to the merest protuberance and in some cases could not be detected with certainty and so
might well be absent. The presence or absence of spurs has usually been treated as of sectional, subgeneric
or even generic significance within the Vaccinieae. Belatedly and no doubt reluctantly, it was impossible
to employ anther spurs as a taxonomically useful character in this species. This is not a wholly satisfactory
solution; it just happens to be the best that can be done now. Extensive field work throughout the range of
V. leucanthum would probably be most helpful in resolving the apparent uncertainties. It would also appear
that the problems associated with this species can only be resolved in conjunction with its relatives in the
Andes of South America and the West Indies.

Vaccinium stenophyllum is characterized by narrowly lanceolate, lance-elliptic to linear-oblong leaves
with prominent venation and mucronate tips, inflorescences of leafy racemes or flowers solitary in the axils
of apparently normal or reduced leaves, a calyx that is articulate with the pedicel, spurred anthers, an often
shortly and densely pilose nectariferous disk, and falsely 10-locular berry. Louis Williams (1965, and in
Standley & Williams 1966) included V. stenophyllum in the Flora of Guatemala even though he stated that *the
material from Guatemala is hardly, if at all, distinguished from V. leucanthum." For this study, no specimens
of V. stenophyllum have been seen south of Jalisco, while V. leucanthum is well-represented in Guatemala.
Plants of V. stenophyllum are not at all reminiscent of V. leucanthum. We agree with Sleumer (1936) that V.
RR is dd a broader leaf form of V. eee

This species was included by Standley (1920-26, pp. 1101-1102) as a member of the woody flora of Mexico,
but its presence north of Costa Rica was questioned by Sleumer (1936) and the species was not included by
Standley and Williams in the Flora of Guatemala (1966). The species is known only from the mountains of
Costa Rica and western Panama. Flowering: throughout the year with the preponderance between Jan—Jul;
fruiting: throughout the year.

racemose inflorescences with small white to pink flowers, spurred connectives (these rarely vestigial), and
glaucous berries. The species varies from small, densely branched shrubs to large trees to 10 m tall. Leaf size
also varies greatly with trees often having leaves at the higher end of the range. The small-leaved populations
of V. consanguineum look especially like V. floribundum. Both species have spurred (or vestigially-spurred)
anthers, although the Costa Rican populations of V. floribundum lack spurs. Nevertheless, V. floribundum
would appear to be its closest relative.

Vaccinium matudae Lundell, a most distinctive species was first described as Gay-Lussacia cordifolia
Martens & Galeotti (21842), but was later determined to be a Vaccinium by Hemsley (1881). In attempting
to form the new combination based on Martens and Galleotti’s binomial, he instead unfortunately pub-
lished Vaccinium cordatum (1881), mistakenly, and carelessly also citing the basionym as Gaylussacia cordata
Mart. & Gal., Bull. Acad. Brux. 9:529. 1842. As a result, instead of establishing the intended and needed
binomial in Vaccinium, Hemsley created an illegitimate name (Article 52 of the ICBN) that is to be rejected
as nomenclaturally superfluous. When Hemsley published Vaccinium cordifolium, there would have been
no obstacle to proposing the binomial Vaccinium cordifolium based on Martens and Galeotti’s binomial, but
after 1894 Vaccinium cordifolium Stapf had been published (Trans. Linnean Soc. Ser. II. 4:189. 1894) and
therefore a combination based on Martens and Galeotti’s ee Re nb EH ina ater a
However, when querried on this problem, three very
J. McNeill, G. Moore, and D. Nicolson) all agreed that Hemsley's melee in transfering Gage
cordifolium M Martens & Galeotti into Vaccinium as V. cordatum OM Martens & Galeotti) Hemsley, while also
mistakenly citing the basionym as G. cordatum, should nevertheless be treated as a correctable error rather
than as the publication of a later invalid synonym that Lundell corrected by publishing a new name since
by that time Vaccinium cordifolium Stapf had been published for a species from Borneo. Consequently, the
American species will be known as V. cordifolium (M.Martens & Galeotti) Hemsley as originally intended,
while the Borneoan plant is provided with a binomial in the footnote below”.

that is articulate with the pedicel, anthers lacking spurs, a greenish Bares and possibly falsely 10 SE
ovaries (mature fruits are needed). Although unable to make better suggestions as to the closest relatives
of the very distinctive Vaccinium breedlovei, we do not see the close relationships with V. poasanum and the
relatives of that species (sect. Leptothamnia Benth. & Hook.f.) as originally suggested by Williams. The
inflorescence pattern would seem to argue against any close relationship with species centered around V.
poasanum, although the stamens do suggest such a relationship.
Vaccinium tolbertianum Lundell was named from perhaps two incomplete collections made by the same
collector at about the same time and place in Guatemala. The specimens (both LL) consisted of attached
leaves, stems, and young fruits. The most unusual feature was the presence of coarse, stiff, rigid trichomes
on a few centimeters of older stem on two of the six sprigs and on a few nearby leaves. Nothing like those
trichomes has been seen in Meso-American vaccinia, but they are frequent in the genus Gaultheria. Other
than for the presence of these gland-tipped trichomes, the specimens would fit reasonably well within the
current concept of V. haematinum Standley & Steyermark. It seems they can still be best placed there in spite
of the presence of those unique trichomes. Obviously further collecting may change our "(— of
this little known variant. Specimens with flowers and trichome-bearing stems are unknown and it seems
reasonable to conclude that without the presence of those coarse trichomes on a few centimeters of certain
of the older branchlets, the species never would have been UM

Distribution —Oak forests, evergreen cloud forests, and mossy thickets, in southern Mexico (Oaxaca
and Chiapas), south through Guatemala (El Quiché, Huehuetenango, and Zacapa) into Honduras (Lempira
and Morazán) and El Salvador (Santa Ana), from 1600-3200(-3700) m. Flowering: (Jan)May—Aug(Dec);
fruiting: throughout the year.
Vaccinium selerianum is a morphologically variable species characterized by its congested leaves that
are elliptic to oblong-elliptic to lanceolate, 2-4.5 cm long, with margins crenate-serrate, short-racemose
inflorescences, an articulate calyx, glabrous to pilose corollas, anthers that lack spurs, and a 4—5-locular
ovary.
Recently, as exemplified by the treatment in the Flora of Guatemala (L.O. Williams in Standley & Wil-
liams 1966), two species have been recognized within what is treated here as a single species of Vaccinium.
They are separated there by the following straightforward couplet:
Flowers glabrous V. haematinum
V. minarum
V
Flowers densely pubescent
The brief descriptions there indicate that the calyces of V. haematinum vary from “sparsely and minutely
puberulent or glabrate." Specimens have been examined with glabrous or at least glabrate calyces and pilo-
sulose corollas. The leaves and vegetative features of both "species" seem to have the same range of variation.
It cannot be claimed that a morphological continuum exists between the two extremes, but the variation
exhibited by the small sample available suggests that a much larger sample would in all probability further
blur the supposed distinctions between the named extremes. It seems that only one, not extremely poly-
morphic species is represented. The extremes in pubescence of the calyx seem to be rather widely bridged,
but there seems to be no similar blurring in corolla pubescense; those previously assigned to V. minarum
have densely pubescent corollas while those attributable to V. haematium are glabrous.
The flowers on the type specimens of V. minarum, V. quicheanum, and V. hondurense are e actly similar
as to pubescence, although the leaves of V. quicheanum are more elongate, while those of V. minarum are
smaller and narrower. As far as the long list of names is concerned, V. selerianum (Loes.) Sleumer (1936) has
priority.

Vaccinium furfuraceum is characterized by its generally densely glandular-fimbriate leaf blades and flo-
ral parts, thin-petiolate leaves with blades that are bullate, apically short-acuminate, and basally rounded,
plinerved venation with the reticulate veinlets conspicuously raised beneath, short calyx lobes, thin and
membranous corollas that are cylindric-campanulate, and staminal tubules that are pubescent along the
inner surfaces and dehiscent latrorsely. The corollas are proportionally conspicuous with respect to the
calyx. Its morphological relationships lie near V. monteverdense and V. jefense with which it has in common
pilose inner surfaces of the staminal tubules and latrorse dehiscence. It also shares densely fimbriate leaves
and inflorescence parts with V. jefense, perhaps its closest relative. Vaccinium furfuraceum differs most con-
spicuously from V. jefense by its possession of an overall shorter calyx (3-4.5 mm long vs. 6-10 mm) and
calyx lobes (1-1.2 mm long vs. 4.5-6 mm), inconspicuously apophysate (not 10-ribbed) calyx tube, and
non-striate calyx limb and lobes.

Vaccinium floccosum is characterized by its alternate to pseudo-opposite leaves with flat blades, entire

with apices longer acuminate, and bases tapering and cuneate. All leaf blades with rounded bases are also
pseudo-opposite, whereas leaf blades with cuneate leaf bases may be either distinctly alternate or pseudo-
opposite. The EE of Eus oes as listed ane Eeer come UNE of the extent of its anomalous
characteristics. The relationships of this species are as close to the species centere d about Vaccinium poasanum
as they are to the largely West salian species usually treated as pL Mes racemosa (Vahl) Stearn (= Horne-
mannia racemosa Vahl). The inclusion of all these species within Vaccinium does not significantly expand the
limits of that extremely diverse genus and still seems to us to be the best treatment for the complex until a
worldwide revision of the generic limits is undertaken. Vander Kloet (1985), whose study was largely based
upon the West Indian V. racemosum (Vahl) Wilbur & Luteyn [= Hornemannia racemosa Vahl and Symphysia
racemosa (Vahl) Stern], argued against such an extension of the generic limits of Vaccinium claiming that
such an expansion “is tantamount to making the genus a dumping ground for any Vaccinieae of uncertain
affinity.” In Vander Kloet’s experience “the character unique to the genus “Vaccinium” is the absence of calyx
tube enlargement prior to anthesis” (see vander Kloet 1985 and vander Kloet et al. 2004 for an alternative
opinion).

Distribution.—Mountain slopes covered by premontane rainforests, on Atlantic slope of Costa Rica
(Heredia and San José) and Continental Divide forests in Panama (Bocas del Toro and Chiriquí), between
(700-)1100-2000 m. Flowering and fruiting: throughout much of the year.
Vaccinium costaricense is characterized by its combination of acutely tapering to rounded leaf blade
bases, a calyx tube that is longer than the limb, corollas that are pilose internally at the throat, and short
anther tubules. Vaccinium costaricense has a longer rachis, shorter calyx limb and lobes, smooth, not stri-
ate, calyx limb and lobes, and longer anther tubules than its morphologically closest relative V. floccosum,
from western Chiriquí Prov., Panama. These differences in the calyx may be influenced by where and how
the plants grow, i.e., epiphytes in the closed forest vs. terrestrial in exposed, windswept areas (JLL, pers.
observ.). Vaccinium costaricense differs from V. orosiense by acutely tapering to rounded leaf blade bases (not
cordate and amplexicaul) and shorter calyx lobes (at least in the Costa Rican populations). The characters
that distinguish these three species of Vaccinium are admittedly few and collections are needed to help
clarify their morphologies and relationships.

Vaccinium orosiense is characterized by its amplexicaul leaves with rounded or cordate blade bases,
short calyx lobes, corollas that are moderately to densely pilose internally at the throat, and by short anther
tubules. When fresh, the basal region of the leaf blades is red, as is also the case in V. costaricense, V. floc-
cosum, and V. luteynii, but usually not in V. poasanum. The relationships of V. orosiense are mentioned under
the discussion of V. costaricense.

ACKNOWLEDGMENTS
Grateful acknowledgment is made to the National Science Foundation whose support over the years made
this study possible. Obviously a study such as the present one would be impossible without the cooperation
of the curators of the many herbaria who loaned their collections for this investigation. We am very much
indebted to the curatorial staff of the following herbaria: A, BM, BR, CAS, CGE, CR, CU, DAV, D5, DUKE,
F, G, GH, INB, K, LL, MICH, MIN, MO, MSC, NY, OXF, P, PH, PMA, POM, RSA, SCZ, TEX, US, WIS. We
know the care and effort each of those loans take to prepare but without their effort this project could not
be undertaken. We also express our sincerest thanks to Bobbi Angell for making the new species come alive
through her beautiful illustrations. We thank Drs. J. McNeill, G. Moore, and D. Nicholson for their advice
on the nomenclature of V. cordifolium for which we are most appreciative. JLL wishes to thank the Missouri
Botanical Garden for providing him facilities to complete this manuscript.

Herbarium work has now revealed the true identity of and the ability to typify Thibaudia laurifolia M. Martens & Galeotti, Macleania
insignis M. Martens & Galeotti, and Macleania coccinea Decne. Orthaea laurifolia (M. Martens & Galeotti) Luteyn is proposed as a
new combination.

INTRODUCILON
In 1967, Yeo wrote a nice little Paper d Tone on some SES of Macleania (Ericaceae).” That paper
helped to sort out the t of Macleania, the species numbered
1—15 in Smith's (1932) Geh of the Thibaudieae. That sions was characterized by having a single
anther tubule and connate staminal filaments, the subgenus Macleania as defined by Luteyn (1997), several
of which are still cultivated. Yeo recognized Smith's taxonomy as “largely satisfactory, but that he [Smith]
has misinterpreted a number of type specimens." ie pue 51 i: of the article, Yeo discussed M. insignis
with its numerous synonyms. Yeo's attempt to clarify the t of some of these names was also largely
satisfactory, but the types of three names discussed b still need further clarification.
Henri Galeotti was one of the first botanical explorers of Mexico. His collections were offered for sale
and this explains their dispersion over many institutions. However, the herbarium (BR) of the National
Botanic Garden of Belgium acquired large quantities of Galeotti material on two separate occasions. A first
and the largest part was purchased after Galeotti's death in 1858, as reported in the minutes of the meeting
of 14 February 1859 ofthe "Société royale d'Horticulture" [which later became the National Botanic Garden].
This was not a complete set, however, of Galeotti's Mexico collection of ca. 7300 specimens (perhaps only
about half). Much later, in 1932, Pierre Martens donated the herbarium of his father Martin Martens to BR.
It contained circa 2000 Galeotti specimens that M. Martens himself had examined with Galeotti. Upon
his return from Mexico, the horticulturist Galeotti developed a collaboration with M. Martens (himself a
professor in chemistry and botany at Louvain). The main output was the “Enumeratio synoptica plantarum
phanerogamarum ...," identifying the Mexico collection and published in a long series of articles presented
at the meetings of the "Académie royale des Sciences et Belles-Lettres de Bruxelles" (Martens & Galeotti
1842—1845) (pers. comm. 2008 with E. Robbrecht).
It is with the aforementioned brief introduction that I set the context for the typifications mentioned
in this paper.
Thibaudia laurifolia M. Martens & Galeotti
In 1842 (page 530), Martens and Galeotti described Thibaudia laurifolia based on Galeotti 1814 (protologue:
leaves short-petiolate, acuminate; racemes elongate, 6—8-flowered). In 1932, in his classic "The American

Species of Thibaudieae,” A.C. Smith cited the Galeotti 1814 sheets at B and US as the “type collection of
Thibaudia laurifolia."
Unfortunately, Galeotti 1814 is now seen to be a mixed collection of at least four elements based on ma-
terial seen at BR, G, K, NY, P, US, and W. These include examples of Macleania insignis, Satyria warszewiczit
Klotzsch, an unknown species possibly Satyria panurensis (Benth. ex Meisn.) Benth. & Hook.f. ex Nied.,
and the true Thibaudia laurifolia. Based on my studies, there were at least 11 herbarium sheets numbered as
Galeotti 1814 including one destroyed at B (after A.C. Smith had seen it), but not including the fragments at
F. All the duplicate collections of Galeotti 1814 seen, except the herein designated lectotype, have original
printed Galeotti herbarium labels (Fig. 1A) that cite the collection locality as “Chinantla” and [Oaxaca]
“Mexico,” and the collector as "H. Galeotti.” All the duplicates were identified as Macleania insignis, with the
Eee of the maa sheet. They are renes by:

The sheets of Galeotti 1814 from B and US that A.C. Smith (1932) cited as the “type collection of Thibaudia
laurifolia” in his “The American Species of Thibaudieae" are now both seen to be M. insignis. In that same
paper, on page 369, Smith also included Thibaudia laurifolia in the synonymy of Macleania insignis. He did
not see (or at least did not annotate) the specimens of either Galeotti 1814 or 1827 at Brussels (BR), but re-
lied on sheets at B and US for his concept. Thus he did not know that Galeotti 1814 was a mixed collection;
therefore, he synonymized Thibaudia laurifolia under Macleania insignis. Nevertheless, the only specimen
that fits the protologue of T. laurifolia is one of the sheets at BR, which Smith did not see, and which bears
an original hand-written specimen collection label (Fig. 1B) that perfectly matches the handwriting sample
for Martin Martens kept at BR (pers. comm. 2008, E. Robbrecht). That sheet has now been properly an-
notated as the lectotype of T. laurifolia and the remaining sheets as Macleania insignis, Satyria warszewiczii,
or Satyria cf. panurensis.
In 1976, Luteyn described Empedoclesia stipitata based on MacDougall 606.5 (holotype: NY). Later,

Luteyn (1987) synonymized the genus Empedoclesia Sleumer under the genus Orthaea Klotzsch and made
the new combination Orthaea stipitata (Luteyn) Luteyn. As a result of herbarium studies carried out in the
United States (F, GH, MO, NY, US) and in Europe in 1986, 2006, and 2007 (B, BR, CGE, E, G, K, L, MA,
OXF, P, S, W), it is now clear that both Thibaudia laurifolia and Orthaea stipitata represent the same species.
Therefore, the new name becomes Orthaea laurifolia (M. Martens & Galeotti) Luteyn.
Macleania insignis
Martens and Galeotti (1842, page 531) also described Macleania insignis in tl ticle as above, based on
Galeotti 1827 (protologue: leaves subsessile, ovate, obtuse, 3-nerved; es fasciculate). The protologue stated
that the species was found on oaks near to the German colony of Mirador at 4000 feet elevation, and that it
was also found in the eastern cordillera of Oaxaca near Talea and Llano-Verde at 5000 and 6500 feet.
Based on my studies, there were at least nine herbarium sheets numbered as Galeotti 1827 including
one destroyed at B, but not including the fragments at F. The original printed Galeotti herbarium labels of
all the duplicates of Galeotti 1827 (Fig. 1C,E) give the general locality as “Cordillera, (Vera Cruz) Mexico,”
along with the dates of “Jun.—Oct.” and “Coll. H. Galeotti, 1840,” although the individual labels of some of
the duplicates seen at BR2x), G, KQx), NY, and P have three small differences with regards to more specific
hand-written information. Two of the sheets at BR mention Llano Verde at 6000 feet (Fig. 1D), while the
sheets at G and P give no specific locality, but do say the plants were “parasite” on oaks; the K-Herb. Hook.
sheet says “parasite on oaks at 4—6000 ft." One of the BR sheets that was relatively recently designated as
“HOLOTYPUS” by P. Bamps (curator at BR) bears two hand-written labels at the bottom of the sheet—one
an original hand-written specimen collection label mentioning “Prés Llano Verde 6000" (Fig. 1D), and the
other an original printed Galeotti herbarium label that reads “Macleania insignis, nobis” (Fig. 1C). This is
the only sheet upon which the original printed Galeotti herbarium label gives the word “nobis”. The two
labels match the handwriting of H. Galeotti based on personal communication in 2008 with E. Robbrecht
(BR). This I feel means that this sheet was seen by the authors and is appropriate to designate as the lecto-
type, which is how I have annotated it. The W sheet reads “Macleania insignis nobis,” but does not have
an original printed Galeotti herbarium label nor is it written in a recognized hand. The other Galeotti 1827
sheets have all been annotated by me as syntypes. All of these are identified as Macleania insignis and are

Macleania coccinea
The name “Macleania coccinea" was first introduced in the protologue of M. cordata Lem. (Lemaire 1848). In
that publication, which included a color illustration of the new M. cordata, Lemaire mentioned that his new
Luteyn, Typifi ti | bination in Eri 247
species was cultivated at the establishment of “M. Jacob-Makoy, de Liége,” having been introduced alive in
1842 or 1843 by “M. Ghiesbregt” along e two other "pes “les i coccinea ... et insignis...
In 1851, Decaisne formally described Macleania a cultivated plant collected by A.B. Ghies-
brecht, presumably from Mexico (see Yeo 1976). The protologue (Decaisne 1851) included a description of
the new species (in French), a paragraph about cultivation techniques for species of Macleania, and a beautiful
color illustration of M. coccinea that as Yeo (1976) mentioned is *very similar" to the one of M. cordata. It does
not, however, give any information about the original collection or its locality; therefore, the actual location of
any type material is still uncertain. There are two herbarium specimens at BR bearing the name M. coccinea,
the one of Linden 432 (barcode S.P. 627954) from the *Collection Martin Martens," donated to BR by Pierre
Martens in 1932, bears the name "Macleania coccinea” on an original hand-written specimen collection label
in the hand of Martin Martens (pers. comm. 2008, E. Robbrecht) (Fig. 1F). The second sheet, Galeotti 1827pp
(type number for M. insignis), also ex "Collection Martin Martens," donated to BR by Pierre Martens in 1932,
has the more explicitly written name "Macleania coccinea Nobis" in the hand of Galeotti on an original printed
Galeotti herbarium label that gives the general locality as “Cordillera, (Vera Cruz) Mexico,” along with the
dates of “Jun.—Oct.” and “Coll. H Galeotti, 1840" (Fig. EE These are the ony two herbarium sheets that I

INTRODUCTION
Siphonandra is a small, distinctive, high-elevation genus of five species that are endemic to the geographical
range from northern Peru (Amazonas) to northern Bolivia (Cochabamba). It was named by Klotzsch (1851)
on the basis of its long and slender staminal tubules, but is also characterized by its articulate calyx, usually
connate filaments, and perfectly terminal pores at the tips of the tubules (Smith 1932; Luteyn 1998, 2002b).
Siphonandra elliptica, the type species, spans the entire geographical range of the genus from northern Peru
(Amazonas) to northern Bolivia (Cochabamba), where it is common. The other four species, however, are
only known from one collection site each, thus making it difficult to assess relationships between any of
the species in this genus. The description of Siphonandra nervosa and S. santa-barbarense brings to three the
number of species found in Peru and to five the number described overall in the genus, which until a few
years ago was only known a the bue e S. elliptica (see Luteyn 20022).
(1932) ically with Lysiclesia (=Orthaea), Ceratostema, and Orthaea
EN A )
on the basis of their hayi ing in common the characte: of articulate calyces and anther dehiscence through
apical pores, although he believed that these similarities were “doubtless derived by distinct and somewhat
parallel courses.” It is true that the genus Siphonandra is morphologically most similar to those species of
Ceratostema that have anther dehiscence by perfectly terminal pores (but there are about as many species
in Ceratostema that have dehiscence through oblique or lateral pores); both genera have articulate calyces,
large corollas, and equal stamens with very slender anther tubules with apical dehiscence. The major dif-
ferences are that Ceratostema has corolla lobes proportionally very long and narrow (usually greater than
4 mm long) and its corolla is also usually basally ventricose, whereas Siphonandra has corolla lobes very
short (equal to or less than 2 mm long) and its corolla is cylindric with parallel sides along its entire length.
Also the geographical ranges of the two genera do not overlap, with Ceratostema ranging from Venezuela
to northern Peru (Piura, Cajamarca), north of the Huancabamba Depression, whereas Siphonandra ranges
from northern Peru (Amazonas), south of the Huancabamba Depression, and into northern Bolivia (south
to Cochabamba). Orthaea seems more distantly related having alternately unequal stamens.
Morphological and molecular studies clarify that Siphonandra is definitely found within the blueberry
tribe Vaccinieae (Kron et al. 2002a). The only published molecular phylogeny of Vaccinieae that included
Siphonandra (Kron et al. 2002b) used matK s HIE data, which placed Siphonandra within an “Andean
clade" sister to a polytomous group containing , Disterigma, and one species of Ceratostema.

A subsequent study within the “Andean clade" did not include Sip! lra (Powell & Kron 2003). Therefore,
the overall data that was based on only one sequence from one Geet of Siphonandra p and
there is still uncertainty about its affinities.

Siphonandra magnifica is herewith maintained despite the fact that the type and only specimen was
destroyed during World War II. Sleumer (1934: 133) mentioned that it “surpasses both species as yet known
[S. elliptica and S. pilosa] in all dimensions”, but differed from S. elliptica by the very short, often indistinct ra-
chis, the very large corolla, the hairy filaments, and the calyx which was covered with fleshy squamules.

the filaments connate, 4—4.5 mm long, glabrous, the anthers 17-18 mm long, the thecae 4.8-5 mm long,
strongly papillose, the tubules 12.5-13.5 mm long, the pores 0.2 mm diam.; style slightly exserted, glabrous.
Berry not seen.
Distribution (Fig. 2).—Endemic to southern Peru (Puno) and known only from the type, collected in
heavily-disturbed, mature montane forest along a river margin, at ca. 2600 m elevation. Endangered due to
its proximity to gold mining and road building activities.
Siphonandra nervosa is characterized by its comparatively large, lanceolate leaf blades with prominent
brochidodromous venation, few-flowered inflorescences, short rachis, pedicels and corolla, and connate
staminal filaments. When fresh the corolla is 5-angled and red with yellowish lobes. Morphologically it is
most similar to S. elliptica, differing primarily in the characters mentioned in the key.

Siphonandra santa-barbarense is characterized by its flat, marginally crenate, obscurely plinerved leaves
with sharply mucronate tips, relatively long rachis, many-flowered inflorescences, articulate (sometimes
inconspicuously) calyx, and staminal dehiscence by obliquely subterminal, elongate pores. The type was
also found growing in the vicinity of S. elliptica.

Guy anais.I
In the past few years, a better understanding of the relationship between taxa of the Boraginales was the
focus of several papers through the re-examination of old and the gathering of new morphological data
and the analysis of molecular data (Diane et al. 2002, 2003; Hilger & Diane 2003; Gottschling et al. 2005;
Miller & Gottschling 2007). Familial and generic limits have been re-considered. In the preparation of the
treatment of the Boraginales for the Flora of the Guianas, I had to decide whether 1 should follow the tra-
ditional taxonomy as used for the Boraginaceae treatments in *Flora of Venezuelan Guayana" (Miller et al.
1997) and in "Checklist of the Plants of the Guiana Shield" (Feuillet et al. 2007) or to adapt it to reflect the
changes proposed since 1997 in the systematic of this group. As it is often the case with work in progress,
some proposals should be adopted, like the era e Varronia P.Br. from Cordia L. (Cordiaceae) and of
Myriopus Small from Tournefortia L. (Heliotropiaceae), when otl 1 further work including more
species in the data sets, like the split of Heliotropium L. and its (eon with Tournefortia s.s. Currently less
than 10% of the species have been analyzed in the whole Heliotropiaceae and it is likely that some major
clades of Heliotropium s.l. and Tournefortia s.s. are missing from the data sets.
The part of the new classification of the Heliotropiaceae proposed by Diane and her colleagues that
is most likely to resist larger sampling is the separation of Myriopus from Tournefortia and its standing as
a sister group to Heliotropium s.l. and Tournefortia s.s. It was pointed out by Johnston (1930) that his new
Tournefortia sect. Cyphocyema 1.M. Johnst. was distinct from the core of Tournefortia. He suggested on a
morphological basis that the two sections of Tournefortia were closer to other genera than to each other.
Small (1933) included two species of sect. Cyphocyema in his new genus Myriopus and said there was more
Neotropical species. The morphological characters that separate Myriopus apart from Tournefortia s.s. are
its elongated corolla lobes, narrow with involute margin, its anthers connate and always hairy at apex, its
drupoid fruits distinctly lobed and not dividing into mericarpids, its four 1-seeded endocarpids that are
strongly curved, and its curved embryos (Johnston 1930; Diane et al. 2002). The molecular and morpho-
logical data sets used by Diane et al. (2002, 2003), Hilger and Diane (2003) confirmed the deep separation
between Tournefortia sect. Cyphocyema and most of the Heliotropiaceae. The Cyphocyema/Myriopus branch
is EE Së Beete Ee of 100% in all trees. Logically Diane et al. (2002) proposed to use
of Tournefortia sect. Cyphocyema. The conspectus presented
boues is Tires the Si? of Myriopus present in the Guianas (Guyana, Surinam & French Guiana) and the
Venezuelan Guayana (Amazonas, Bolivar & Delta Amacuro), the most part of a region often referred to as

Both Dryander (1789) and Lamarck (1789) published a taxon named Passiflora heterophylla. According to
TL-2 (Stafleu & Cowan 1976), Dryander’s name was published between Aug 7 and Oct 1, while Lamarck’s
name was from Oct 19 (Stafleu & Cowan 1979), thus giving Dryander’s name priority. Killip (1938) ac-
cepted Lamarck's species and name but cited Dryander’s as a synonym under P. suberosa L. as “Passiflora
heterophylla Dryand. in Ait. Hort. Kew. 3:309. 1789, not P. heterophylla Lam.” Dryander's species is now con-
sidered a synonym of P. pallida L. in subgen. Decaloba supersect. Cieca (Medic.) J.M. MacDougal & Feuillet
(Porter-Utley 2003) and P. heterophylla Lam. is a good species without a valid name and without synonym.
Passiflora heterophylla “Jacq., Hort. Schoenbr. t. 181. 1797” is Dryander's species because Jacquin credited
“Ait. kew. vol. 3. pag. 309.” There is no name available for the taxon currently called P. heterophylla Lam.,
so we propose the following new name:
— insueta Feuillet @ MacDougal, nom. nov. lla Lam., Encycl. 3:41. 19 Oct 1789, non
. 7 Aug-1 Oct 1789. (including the Latin diagnosis). Tyee: HAITI: ases à Pitres, omn Icaque, Plumier? s.n. (HOLOTYPE: Pt).
Passifl ta belongs in sub Decalol t. Multiflora (Small) J.M. MacDougal & Feuillet (Feuil-
let & MacDougal 2003). The leaf blades of this poorly known species are lobed nearly to the base and the
lobes themselves are unlobed or lobed in their apical half.
Etymology.—The epithet comes from the Latin adjective “insuetus” meaning “unusual” in reference to
the leaf shapes.
Passiflora insueta is known from Haiti and western Cuba.

This paper is the first of a series describing new species of Gesneriaceae from the Venezuelan Guayana.
This region of Venezuela includes the states of Amazonas, Bolívar, and Delta Amacuro, totaling 454,000
km? that represents 50% of the area of Venezuela. The two new species of the subfamily Gesnerioideae
Link described herein belong to Besleria L., tribe Beslerieae Bartl. & H.L. Wendl., and were collected in the
state of Amazonas.

part of the Municipio Río Negro, Amazonas (Venezuela) near the base of Cerro d la Neblina, at 100-140
m elevation. The Neblina massif is on the border with Brazil and it is possible that populations of this new
species are present in nearby Brazil.
Phenology.—Blooming probably not seasonal, documented in February-March, May, July, November.
Besleria neblinae corollas have a spur at the base that prolongs the tube at a 0-20” angle (cf. Fig. 1 inset)
and displaces the attachment to the receptacle in a lateral position. According to Morton (1939), this char-
acter places B. neblinae in sect. dcl CV. E Geer, its obsolete inflorescence peduncle
and the size of the corolla limb indicate the sp long t. Axillares CV. Morton, one of the two
subsections of sect. Neobesleria that remain alter hve were transferred to the reinstated genus Gasteranthus
Benth. In the same subsection and from Amazonian Brazil and Venezuelan Guayana, B. gibbosa (Poepp.)
Hanst. also has white corollas, but B. neblinae differs by: 1) the leaf blades which are clearly unequal in a pair
(versus equal or subequal) and narrower, 2) the calyx lobes that are longer, narrower, and hirsute (versus
glabrous), and 3) the dorsal glands that are smaller. In the specimen Liesner 17300, most pairs of leaves are
subequal but the smaller petioles are 1/2 as long as the larger ones which is distinctive from B. gibbosa. The
collection Thomas 3396 was made in the same locality and the same day as the type collection, Gentry &
Stein 47253. Although a different collection (W. Thomas, pers. com.), it is possible that both represent the
same population. This species was Besleria “sp. B" in Feuillet and Steyermark (1999).
Etymology.—Besleria neblinae is named for Cerro de la Neblina near the base of which all the known
collections have been made.

Feuillet, New species of Besleria 273
It has white corollas like B. gibbosa and B. neblinae, but differs from the first one in having leaves that are
strongly unequal in a pair (versus equal or subequal) and long acuminate (versus acute to acuminate), its
longer and appressed-pubescent (versus glabrous) calyx lobes, and its smaller dorsal gland Besleria yatuana
differs from B. neblinae in having the leaf blades adaxially glabrous (versus appressed pubescent), the calyx
minutely appressed pubescent (versus hirsute), calyx lobes free to the base, and the slightly shorter corolla
tube. Besleria yatuana was Besleria “sp. C” in Feuillet and Steyermark (1999).
Etymology.—Besleria yatuana is named for the Río Yatúa near which the type specimens have been col-
lected.

The two new species of the subfamily G joideae Link described below were collected in the Venezuelan
state of Amazonas. They belong to Eun Mart. in the tribe Episcieae Endl. Since the regional treatment
by Leeuwenberg (1958) and the formal infrageneric classification he proposed for Episcia, the genus has
been split into four groups. Most authors now follow Wiehler (1973, 1978) in adopting Alsobia Hanst. and
Paradrymonia Hanst., as well as the transfer of several Episcia species to Nautilocalyx Linden ex Hanst. The
transfer to the other genera affected all the species of six of the seven sections and in section Episcia, three
of the five subsections. The current concept of Episcia is the equivalent of two of the subsections of Leeu-
wenberg (1958), i.e. section Episcia subsections Episcia and Trematanthera Leeuwenb., and follows the most
recent molecular studies (Smith 2000; Zimmer et al. 2003; Clark et al. 2006).

hirsute, trichomes 2-2.5 mm long; blade carnose, suborbicular-ovate to broadly elliptic, 2—4.5 x 14-2.5
cm, base rounded to obtuse, apex rounded to broadly obtuse, margin crenate, with dense, long, appressed,
yelow trichomes on both surfaces, except above on s main veins that show their dark green color, 3—5
ide of the midrib, ending i in margin sinuses reduced pair- -flowered cyme,
fasciculate, 1-4-flowered, axillary in the apical part of the stem with small leaves still growing; pedicel about
8 mm long. Flowers with sepals free, entire or 1-2-toothed in apical half in the same flower, lanceolate to
oblanceolate, 8-9 x 1.5 mm, densely hirsutulous on both sides, the posterior one slightly involute and nar-
rower; corolla held transversal in the calyx, crimson, basal gibbosity 3 x 4 mm, uniformly densely pilose,
tube 15-18 mm long, densely appressed-pubescent outside, inside papillate in apical third and glabrous
below, lobes suborbicular, rounded, serrulate, 7 x 4 mm, glabrous on both sides except at very base where
joining the tube; stamens inserted about 2.5 mm above base of corolla tube, filament glabrous, broadened
at base, anthers suborbicular, 1.5 x 1.2-1.5 mm; dorsal glands fused in a tongue-like gland, about 1 x 1
mm; ovary superior, ovoid, 3 x 3 mm, densely sericeous—pilose, style 12 mm long, densely pilose. Capsule
globose, 4.5-5 mm long.
Distribution.—Episcia duidae is known from Cerro Duida (Munic. Alto Orinoco) and Serranía Parú
(Munic. Atures) in the state of Amazonas (Venezuela) between 1500 and 2000 m. It was collected at the
bases of waterfalls and in wet crevices.
Phenology.—1t has been collected in bloom in February-March and November, and in fruit in Febru-
Episcia duidae resembles the red-flowered species of subsection Episcia: E. andina Wiehl., E. cupreata
(Hook.) Hanst., and E. reptans Mart. Inside the corolla tube, E. duidae has the apical third with large papil-
lae, E. cupreata and E. reptans have a ring of glandular trichomes in the throat, E. andina is said to have
a corolla glabrous inside (Wiehler 1984; but this could not be checked). The style is densely pilose in E.
duidae, unknown in E. andina, and glabrous in the other two, occasionally with scattered trichomes at the
apex in E. cupreata. Ge duidae and E. andina differ from the other two by much smaller leaf blades with
a long dense app | on both sides rather than hirsute leaf blades found in the other two spe-
cies. The corolla of E. tenian is about twice as long as in the other three; it is cylindric and nearly straight
in E. duidae and E. reptans, infundibuliform and straight in E. andina, and clearly curved in the middle in
E. cupreata. E. duidae differs from E. cupreata by the dense appressed (versus hirsute) indumentum on the
leaf blades, the corolla posture transverse (versus oblique) in the calyx, with a tube straight (versus curved
near middle), densely appressed-pubescent (versus pilose), smaller corolla lobes, and a style densely pilose
(versus glabrous or with a few trichomes near the apex). Episcia duidae was “sp. B” in Feuillet and Steyermark
(1999), where it should be noted that numbers 2 and 3 were switched in the first bracket of the “Key to the
species of Episcia” in that publication.
Etymology.—The new species is named after Mt. Duida at the base of which the type specimens have
been collected.

Distribution and phenology.—Episcia rubra is known only from the type collection from crevices in
moist, shaded, rocky canyon along a tributary of Río Coro-Coro, in Amazonas, Venezuela, around 200 m
in elevation. It was blooming and had young fruits in February.
The anthers dehiscent only in the basal half place Episcia rubra in sect. Trematanthera with E. fimbriata
Fritsch and E. sphalera Leeuwenb. among which it differs by its red corollas.
Etymology.—The new species is named after the color of its red corolla, unique in Episcia sect. Trema-
tanthera.

In Feuillet (2007) two new species were described in Passiflora subg. Passiflora supersect. Coccinea Feuillet
& J.M. MacDougal, and a key to the species was given. In that paper, one branch in bracket 11 of the key
led to “P. sp. (Guyana)", known only from photographs. Since publication of that manuscript, herbarium
material has become available, thus allowing a good description to be drawn from actual specimens. This
new species is described as Passiflora tecta

Liana climbing on shrubs and small trees at forest edge, probably reaching the canopy. Young stems terete,
slightly striate, with short, irregularly curved trichomes. Tendrils long, thin, with short arched trichomes.
Vegetative bud in apical position, less than 1 mm away from the rest of the axillary complex (petiole, stipules,
pedicel, tendril), prophylls acuminate at apex, densely short-pubescent. Stipules linear, 2.5 x 0.8 mm,
short-pubescent, deciduous before the leaf differentiate in petiole and blade, leaving a round scar. Petiole
8-12 mm long, curved at base, with 2 lateral glands at the very base; glands scar-like, glandular surface
oval, ca. 1 x 1.5 mm, with 1-2 tufts of long white trichomes, otherwise glabrous, rim minute pubescent.
Blade ovate, 5-10 x 2.5—6 cm, bi-serrate, teeth ending in small, stipitate, round glands, acuminate and
mucronate at the apex, broadly cordate and briefly cuneate at the base, drying brown adaxially and yellow-
brown abaxially, 2-3 main lateral veins on each side of the midrib, the first pair about 2/3 as long as the
midrib, tertiary venation scalariform. Inflorescence sessile, 1-flowered. Pedicels erect, 4.5—6.5 cm long, with
dense short pubescence. Bracts three, verticillate, orange red, ovate, concave, 3-5 x 2-2.5 cm, free to base,
round at the apex, glandular serrate at the margin on the apical two-thirds, with dense short trichomes
on both surfaces. Flowers orange red, perianth lobes adaxially whitish at base; hypanthium 7 mm long, 9
mm broad on live material, round at base, inflated with the point of contact with the pedicel invaginated,

Distribution —The only specimen of Passiflora tecta known to me was collected in flower from Guyana,
in Tue Potaro- EE EE near Peer Mountain in a clearing at the edge of the forest in September 2006.
phed twice in Guyana, once in February 1990 (C. Feuillet) in the Upper
Takutu- oe Essequibo num near Surama, at the forest edge along a dirt road (with bud and young fruit),
and again in Rep SE (C. Kelloff) in the Rotator paral region, in Kaieteur National Park (flower),
though no herl were made. The three localities are in western centra ] Guyan a and the plants
were collected or Bst graphed at the edge e lowland rainforest (less than 500 m elevation Passiflora tecta
could be easily confused with P. coccinea, the most common species of Passiflora in the Guianas.
Passiflora tecta sp. nov. clearly belongs to P. subgen. Passiflora supersect. Coccinea due to its distinctive
leaves with serrate margins, red floral bracts with glandular-serrate margins, red-colored perianth, and
straight corona filaments that form a cone angled towards the androgynophore. In this supersection, P. tecta
most closely resembles P. coccinea Aubl. (Fig. 3), a species with a large Amazonian and Guianan distribution
described from French Guiana (Aublet 1775). However, the Guianan endemic P tecta has narrow-elliptic
rather than ovate bracts and red rather than white outer corona filaments. Passiflora tecta also resembles P.
miniata Vanderplank (Fig. 4), described from western Amazonia (Colombia, Brazil, Peru, and Bolivia) by
John Vanderplank (2006), from which it differs in its outer corona fil ts that are orange-red and slightly
oblique inwards, rather than dark purple and slightly oblique outwards.
Etymology.—The Latin specific epithet means "covered." This refers to the tl f fil t
that restrict pollinator access to the nectar chamber contrary to the condition in P. miniata, where only the
innermost row of filaments guard the throat.

woetully ied. Concentrated biodiversity studies in the Department of Cusco
in s ae Peru (www.andesamazon.org) have recorded many species in the genus, some new to Peru
and some, no doubt, new to science. Critical study and dissemination of this information has just begun
(Repasky & Christenson, in press)
Recent collections of Pachyphyllum ecallosum from the Department of Cusco, Peru, have emphasized
the distinct nature of its inflorescence. Unlike the few flowered inflorescences of the type collection from
the Department of Huancavelica, more recent collections consistently bear 4—6 flowers arranged in a well
defined capitulum. A new section is proposed for P. ecallosum and its sister species, P. tortuosum. In addition,
the genus Orchidotypus is given formal status as a section of Pachyphyllum.

Baccharis riograndensis Malag. & J.E. Vidal, an endemic species from Rio Grande do Sul State, in southern
Brazil, was described by Malagarriga (1949, under his monk name Irmáo Teodoro Luis) based on two speci-
mens collected by J.E. Vidal (syntypes) and two collections (paratypes) made by Malagarriga himself. After
the publication, accounts of this species appeared in the taxonomic literature several times (Malagarriga
1957, 1958, 1977, Barroso Mid Diesel 1987; and Oliveira et al. 2007), but no lectotypification was made.
The study of the synt at Herbarium R, Museu Nacional do Rio de Janeiro, along with general
collections de various herbaria: confirmed this taxon as distinct and allowed a choice of lectotype. Along
with the lectotypification, additional data ted, including a hological description, illustration,
specimen citations, geographic distributional map, and IUCN (2001) status a conservation.

and sparsely in the northern half (islands of discontinuous grassland areas on plateau sites inserted in the
Atlantic Forest biome). Increasing land use and planned forest projects may disrupt the habitat of the spe-
cies. Due to the anthropogenous pressure on the south Brazilian subtropical grasslands (campos) with the
increasing of displacement of native vegetation in substitution to large-scale Eucalyptus and Pinus plantations,
the species is E as Near Threatened (NT), concerning the IUCN (2001) status of conservation.
Comments.—Baccha lensis is assigned to subgen. Molina Heering and sect. Caulopterae DC., to
the latter mainly die: to estado of winged stems, clinanthium with glandular hairs, and pappus bristles
of female flowers that are enlarged basally and fused into a ring. Seege lo aq pl is SE in its
entire limited range to Baccharis crispa Spreng., which has a wider distribut l area in sout South
America. Similar characteristics to the both species are the similar habitat, erect branches with undulate
wings, involucre of male capitula campanulate and uniseriate pappus in male and female flowers. Baccharis
riograndensis differs from B. crispa due to the fertile branches distinctly narrow-winged (vs. not distinctly
winged fertile branches), lateral spikes reduced to solitary capitula (vs. lateral spikes fully developed or
294 t tani titute of Texas 2(1)
with reduced axis seeming glomerules), involucre of female capitula cylindrical (vs. campanulate) and
larger cypselas, 2.5-4 mm long (vs. smaller, 1-1.5 mm long). Another taxon, similar to B. riograndensis, is
the alopatric Baccharis genistelloides subsp. lorentzii Joch. Mull., from central Argentina, which shares some
characteristics with B. riograndensis, such as the pseudospikes with the lateral spikes generally reduced to
one capitulum, cylindrical involucre of female capitula and larger capitula and cypselas, but differs on the
basis of its erectopatent branching (vs. erect), usually narrower capitulescences (vs. wider), fertile branches
not distinctly winged (vs. distinctly narrow-winged fertile branches), fewer cypsela ribs (9-12 vs. generally
12-20) and multiseriate pappus (vs. uniseriate).

Calyptranthes websteri is distinguished from all other Andean species by the elongate peduncles and
pedicels of the many-flowered inflorescence. This very distinctive species is named in memory of its dis-
coverer, Grady Webster, an astute student of the Euphorbiaceae and respected teacher at the University of
California, Davis, who passed away in 2005.

Eugenia concava is characterized by small, elliptic, glabrous leaves, abruptly acuminate at apex, the
midvein convex on the upper surface; the inflorescences are fasciculate, with slender pedicels and flowers
with concave calyx lobes. The pulp is characterized as "sweet" by Palacios & Rubio (9977). Eugenia concava
resembles E. rhombea Krug & Urb., a species from Southern Florida, Mexico, Central America, and West
Indies (McVaugh, 1989), but differs by the leaves with distinctly convex midvein (vs. concave), lacking a
distinct cartilaginous leaf — (vs. present), and by the ellipsoid fruits (vs. globose).

INTRODUCTION
The present work seeks to clarify the status of the incorrect, confused, and/or misapplied names [e.g., Bor-
reria flavovirens Bacigalupo & E.L. Cabral, Borreria gymnocephala DC., Diodia gymnocephala (DC.) K. Schum.,
Diodia schumannii Standl. ex Bacigalupo] of taxa related to Spermacoce schumannii (Standl. ex Bacigalupo)
Delprete (Rubiaceae, Spermacoceae).
Candolle (1830, p. 549) described Borreria? gymnocephala DC., and was uncertain deet its generic
position. He cited a specimen in his herbarium without giving the collector or tl ollection locality.
After the description he stated that this species, collected in Brazil, is so distinct that it could even be treated
as a separate genus and is cl terized by 4-angular, smooth stems between the capitate inflorescences and
small Ronda with included anthers.
Schumann (1888) transferred Candolle’s taxon to the genus Diodia as D. gj hala (DC.) K. Schum.
After the description, he stated that it is very similar to Borers latifolia (Aubl) K. Schum. var. siderites
(Cham. & Schltdl) K. Schum., from which it differed by the yellowish color of the vegetative parts and the
fruit and style morphology. However, both Schumann's description and the specimens he cited apply to a
mixture of two species.
According to Bacigalupo and Cabral (1998), Se was ME d to notice that Schumann's Diodia
gymnocephala suco Md two distinct species. He specimens EEN e to
the part of D. gy la that differed from Candolle's B i hal B
Bacigalupo (1974) ened this same sf volume 6, part 6 ofi the Flora Ilustrada de Entre Ríos (Argentina),
and published Standley's name as “Diodia schumannii Standley ex Bacigalupo, nov. nom.” with Schumann's
D. gy hala listed as a synonym and Candolle's B. gymnocephala specifically excluded. Article 69 of the
ICBN (Stallen et al. 1972) in force at that time stated that “A name is to be rejected if it is used in different
senses and so has become a long-persistent source of error.” Whether Bacigalupo intended to completely

reject D. gymnocephala (DC.) K. Schum. or was simply creating a new name for D. gymnocephala sensu K.
Schum. is not entirely clear in this Flora, since no further discussion of nomenclature was provided.
Since the type of D. gymnocephala, i.e. Borreria gymnocephala DC., was explicitly excluded by Baciga-
lupo (1974), the citation of this earlier name does not make D. schumannii illegitimate under current ICBN
Art. 52 (McNeill et al. 2006). But, apart from having the correct Latin form, does this name meet the other
requirements under Art. 32.1 for valid publication, namely provision of a Latin description or diagnosis
(since 1935) and indication of a type (since 1958)? Bacigalupo (1974) provided only a Spanish description,
but her reference to Schumann's name, for which a full Latin description was provided, is an acceptable
"reference to a previously and effectively published Latin description" under Art. 36. In addition, under
this species Bacigalupo cited only the single specimen “Dpto. La Paz, isla Curuzú Chalí, Burkart 27.103
(SD." When Bacigalupo (1974) published her new species, Art. 37 of the ICBN (Stafleu et al. 1972), then in
effect, stated: "Publication on or after 1 Jan. 1958 of the name of a new taxon of the rank of family or below
is valid only when the nomenclatural type is indicated ..." thus her citation would not then have satisfied
this requirement and her new name was not validly published under the 1972 Code.
It was this fact that motivated Bacigalupo and Cabral (1998) to later propose a new name, B. flavovirens
Bacigalupo & E.L. Cabral, to replace Diodia schumannii Standley ex Bacigalupo, “nom. illeg.”, which had
been published “sin seleccionar el tipo”, although in reality this shortcoming would have affected its valid
publication and not its illegitimacy. However, these authors had overlooked the fact that already in the 1988
ICBN (Greuter et al. 1988) Art. 37 had been expanded considerably to include, in Art. 37.3, the following:
"for the name of a new species or infraspecific taxon, citation of a single element is acceptable as indication
of the holotype.” In the current ICBN (McNeill et al. 2006) this is now stated as: “for the name of a new spe-
cies or infraspecific taxon, mention of a single element or gathering ..., even if that element is not explicitly
designated as type, is acceptable as indication of the type." Since Bacigalupo's (1974) citation of a single
specimen fulfills the requirement for a type indication, D. schumannii has been validly published under all
editions of the ICBN since 1988. Thus B. flavovirens was at the outset a nomenclaturally superfluous and
illegitimate replacement name for D. schumannii.
In their 1998 paper, Bacigalupo and Cabral finally clarified the status of Diodia gymnocephala (DC.) K.
Schum., which from their examination of the type of the basionym, B. gymnocephala DC. (1830), at G-DC
they determined to be synonymous with Borreria palustris (Cham. & Schltdl.) Bacigalupo & E.L. Cabral,
this based on the earlier Diodia palustris Cham. & Schltdl. (1828).
A further point should be made with regard to the type of Diodia schumannii Standley ex Bacigalupo.
Because this name was *validly published by reference to a previously and effectively published description
or diagnosis,” that of Schumann (1888) as has already been noted, Art. 7.7 dictates that it “is to be typified
by an element selected from the context of the validating description or diagnosis, unless the validating
author has definitely designated a different type.” While Bacigalupo can be said to have satisfied the Art. 37
requirement for "indication" of a type, according to Art. 7.11 “designation” S a a EH the Meuse of
Luna a] mat
“the term ‘type’ or an equivalent.” So unless the term “Exsiccata” used by B
o “type,” which seems unlikely, does this mean that the indication of type ner Art. 37 does not Poss,
as Mi LN of a different type under Art. 7.7, such that D. schumannii must be typified on an element
cited by Schumann? It is our interpretation that in this case an "indication" in the one case is equivalent to
a "designation" in the other, such that the type of D. schumannii is that indicated by Bacigalupo in 1974.
In conclusion, the species discussed above is maintained within the genus Spermacoce, as S. schumannii
(Standl. ex Bacigalupo) Delprete, following the circumscription adopted by Delprete et al. (2005), Delprete
and Cortés-B. (“2006” [2007]), and Delprete (2007).

INTRODUCTION
The genus Aristida I | 250—350 species, nearly worldwide in distribution, growing in warmer,
more arid environments (Allred 2003). Members are characterized by a panicle inflorescence, one-flowered
spikelets, and relatively large glumes, usually larger than the floret. The florets are characterized by three
awns, the two lateral awns absent or much reduced in some species, and a sharp pointed callus with a tuft
of hair at the base. In some cases the lemma body is drawn out into an elongated beak below the divergence
of the awns. The genus has its share of taxonomically difficult species complexes. Members of such groups
often differ only slightly morphologically and commonly overlap in their geographic distribution (Allred
1984a, 1984b; Longhi-Wagner 1990).
The Aristida gibbosa complex is one such group. This New World complex is characterized by the fol-
lowing two features: 1) floret sulcate, the margins of the lemma slightly overlapping, and 2) callus short,
0.3-0.4 mm long, the attachment scar circular and tiny, 0.2-0.3 mm in diameter (Fig. 1). New World taxa
corresponding to these features have received the following names (in chronological order):
Chaetaria gibbosa Nees (1829): In his ample description, Nees noted the regular branching of the
culms, short lower sheaths exposing the gibbous nodes (whence the specific epithet), and folded or rolled
leaf blades. Blade margins are not thickened, the marginal veins being no wider than those inward, and the
adaxial surface is lacking pilose hairs except at the corners of the sheath. Panicles lack pulvini and are thus
narrow and contracted. This is a South American species, and the name was unused in North and Central
American works until Longhi-Wagner (1990) called attention to the sulcate lemma of numerous specimens
J. Bot. Res. Inst. Texas 2(1): 309 — 322. 2008.

at MO and US and annotated them as this. The name was then applied, in an expanded
sense, to Meso-American plants by Pohl and Davidse (1994) to include Aristida sorzogon-
ensis, A. orizabensis, and A. marginalis.
Aristida sorzogonensis J. Presl (1830): Erroneously believing Haenke's specimen
to be from Sorsogon on the island of Luzon in the Philippines, Presl applied the specific
epithet sorzogonensis to his new species. It is highly probable that the specimen actually
came from Central America or Mexico (annotation in 1921 on the type by E.D. Merrill;
Henrard 1928). The type collection is represented by at least two sheets, both with a single
flowering culm: the holotype at PRO) has three mid- to upper blades, but lacks the base
of the plant or any basal blades; an apparent isotype at PR(!) has a culm with three upper
blades and two mid- to lower blades. Presl described the blades as convolute-setaceous,
which the upper are, but the middle and lower blades are flat (perhaps rolled a bit upon
drying) in both specimens. Blade margins are noticeably thickened, with a wide band of
sclerenchyma at the margin; this is easily visible even on the upper blades that are rolled.
The adaxial surface has prominent pilose hairs upwards from the throat region. A close
examination of the panicle branches and pedicels reveals small (perhaps young) pulvini
in nearly all the axils, with the resultant slight spreading of the axes, a feature not noted
“this species in any previous works. The name Aristida sorzogonensis has been largely
ignored or unknown by nearly all North American botanists, even though Henrard recog-
el, ue nized it in both his Revision and Monograph of Aristida (Henrard 1929, 1932). Pohl and
paesi idse (1994) rightly called attention to the priority of j izabensis and
rre “2 ) rightly called attention to the priority of sorzog over orizabensis an
marginalis, but we believe they misinterpreted the typification in tentatively applying the
name sorzogonensis to plants with rolled, rather than flat, blades
Aristida liebmanii E. Fourn. (1886): Fournier's description came from a collection
by Liebmann (whence the specific epithet) and noted the following distinctive features: basal blades are flat
and the upper blades are rolled (much as in the type of A. sorzogonensis), and first glumes are longer than
the second. He did not call attention to the nearly complete absence of an elongated beak on the lemma,
the awns immediately diverging from the apex, but this was stressed by Henrard (1927), is easily observ-
able in the type, and was re-emphasized by Pohl and Davidse (1994). An isotype at MOO) contains three
Se Se and one basal portion. Tue margins of the blades are noticeably thickened, and the lower
lat the base hat flexuous. Panicl pulvinate. Pohl and Davidse
(1994) called attention to its similarity with A. succedeana Henr., a species of Bolivia and Brazil that also
has sulcate lemmas, flat blades, and sub-flexuous panicle branches, with the suggestion that the two may
be conspecific. However, because of the scarcity of specimens further analysis and conclusions concerning
this species must await the availability of more material.
Aristida orizabensis E. Fourn. (1886): Fournier’s description, though short, mentions flat blades
(rolled upon drying), somewhat unequal glumes, and a narrow lemma that was slightly shorter or longer
than the glumes. Material came from “Valle de Orizaba,” Veracruz, Mexico (whence the specific epithet),
with Fournier citing two specimens, which are considered syntypes. Isosyntypes at NY() and USC) have
flat, curling blades with thickened margins and with long pilose hairs on the adaxial surface near the ligule,
and panicles lacking pulvini. Henrard (1927) contrasted A. orizabensis with A. arizonica Vasey and A. appressa
Vasey, two species excluded from this complex that lack sulcate lemmas.
Aristida marginalis Ekman (1911): This species was named from material collected along the dry,
grassy edges of forests or woods (“in margine silvulae,” whence the specific epithet) in Matto Grosso, south-
ern Brazil. The new species is very well described by Ekman. In type material (isotypes G!, US!), sheaths
are about half as long as the numerous internodes with gibbous nodes; lower blades are flat, curling, and
thick-margined with pilose adaxial surfaces; the panicle is obscurely and incompletely pulvinate Oe. with
poorly developed pulvini in the axils of some branchlets and pedicels); and the lemmas are sulcate with a
scar (arrow).
Strahan and Alired, Re-evaluation of the Arístida gibbosa complex 311
short, circular callus. Longhi-Wagner (1990) subsumed this name under A. gibbosa, using comparisons of
spikelet features such as beak length and relative glume length. The name A. marginalis has been applied to
numerous Mexican specimens with flat, curling blades and well-developed pulvini.
This study investigates the relationships among Aristida gibbosa, A. sorzogonensis, A. orizabensis, and
A. marginalis using multivariate analysis of morphological characters scored from herbarium specimens to
assess species boundaries and determine the usefulness of certain traits used to distinguish them.
MATERIALS AND METHODS
For analysis of taxonomic relationships, specimens identified as Aristida gibbosa, A. sorzogonensis, A. oriz-
abensis, and A. marginalis were obtained from the following herbaria: F, G, MO, NMCR, US, and WIS. All
specimens were examined for a sulcate lemma to distinguish them as members of the A. gibbosa complex.
A complete examination of all specimens yielded 90 OTUs (operational taxonomic units) for the analysis,
including t fA. gibbosa, A. sorzogonensis, A. orizabensis, and A. marginalis. The specimens used
represented the full geographic distribution of the species complex from northern Mexico through Central
and South America. A complete data set is available upon request. Roughly two-thirds of the specimens
received that were identified in herbaria as A. orizabensis were actually A. appressa, and not included in this
study. In addition to not having a sulcate lemma, A. appressa develops a thicker beak (0.2-0.3 mm), usu-
ally longer lemma (7-16 mm), and longer callus (0.6-1 mm) with a longer, elongated (rather than circular)
attachment scar.
Each OTU was scored for 13 characters, seven discrete and six continuous (Table 1). All discrete
characters were oes for mature vegetative features as pe or absent, with and without the aid of a
dissecting mi di the nature of the character. All spikelet ts were taken using
e
an ocular comer on a dise cine microscope and were obtained from one mature spikelet from each
specimen. Panicle measurements were taken using a standard metric ruler. Principal components analysis
(PCA) of the standardized data was conducted using Kovach (2005).
RESULIS AND DISCUSSION
An initial PCA of all OTUs indicated morphological differences with 83% of the variability among speci-
mens occurring along the first three components (Table 2). This is due in part to high variable-to-variable
correlations among various discrete features of leaf blade pubescence, type of blade involution and curling,
thickness of margins, and shape of nodes (Table 3); the high correlations render these features taxonomi-
cally important.
Component I accounted for 60.196 of the variability among OTUs, mostly reflecting weak correlations
of vegetative features. Component II accounted for 14.996 of the variability, correlating variation in awn and
glume lengths, and Component III correlated with pulvini and panicle length (Table 2).
Dispersion of OTUs was greatest along the first two components, with resolution bet two morpho-
logic groups occurring along component I (Fig. 2). The two groups were distinguished by a combination of
vegetative and spikelet features. OTUs corresponding to Group 1 are characterized by leaf blades folded and
straight (Fig. 3), gibbous nodes (Fig. 4), lacking pilose hairs on the adaxial surface, margins not thickened
(Fig. 5), smaller glumes, shorter awns, and shorter callus to awn lengths (Figs. 6-7). OTUs clustered in Group
2 are characterized by contrasting features: curling leaf blades (Fig. 8), terete nodes (Fig. 9), leaf blades flat
with thickened margins and prominent pilose hairs on the adaxial surface (Fig. 10), larger glumes, longer
awns, and longer callus to awn lengths (Figs. 11-12). The type of Aristida gibbosa fell within Group 1, and
the types of Aristida sorzogonensis and A. orizabensis fell within Group 2. The placement of the type specimen
of A. marginalis between Groups 1 and 2 is a result of its having some features of Group 1 (gibbous nodes,

was conducted on all 54 OTUs of Group 2 (Fig. 13). The first three components of the PCA explained 82%
of the variability of this second analysis (Table 4). Dispersion of OTUs along component I was a function of
variability in awn lengths, glume lengths, and callus to awn length. Component II revealed differences in
the central awn, glume two, and panicle lengths, as well as the pulvini development. Component III cor-
responded to variation in panicle length and pulvini development (Table 4).
Dispersion of Group 2 OTUs reveals no further clear morphological distinctions, nor a clear separation
between pulvinate and non-pulvinate forms, in spite of these being visually distinctive. Axillary pulvini
cause panicle branches and pedicels to spread outward, giving the panicle a somewhat diffuse appearance,
contrasting with the dense contracted appearance of non-pulvinate panicles (Figs. 14—17).
In summary, spikelet feat are deceptively similar among the three species analyzed, and may lead
one to consider them as conspecific. In contrast, vegetative features, though often thought to be of lesser
value in grass taxonomy, serve very well in distinguishing the species.

TAXONOMIC TREATMENT
Consequent to the results of the PCA, three species are recognized (in addition to A. liebmannii, which was
not analyzed in this study): Aristida gibbosa (Group 1 OTUs), Aristida sorzogonensis (Group 2 OTUs), and
Aristida marginalis (represented solely by the type specimen). Variation in features is described in Table 5.
The recognition of Aristida marginalis (based on the two isotypes from a single collection) is problematic,
since so little is known about it. It is distinguished from the other two species by a suite of peculiar vegeta-
tive features: taller, more robust culms with numerous nodes and conspicuously short sheaths, about half
as long as the internodes, exposing the many gibbous nodes. Other features are a mix of A. gibbosa and A.
sorzogonensis: ak during DAMES with adaxial pilose hairs characteristic of A. sorzogonensis, and gibbous
nodes and | Ims teristic of A. gibbosa. We leave the name A. marginalis intact until further
analyses are Bosse

Aristida gibbosa is characterized by blades that are folded or rolled, stiffly erect, glabrous, and usually lacking
thickened margins. The culms regularly branch above the base and have prominently gibbous nodes, with
2—6(—8) nodes elevated above the base. Panicles are narrow and non-pulvinate.
Distribution.—South America: Bolivia, Venezuela, British Guiana, and Brazil (Fig. 18).

Aristida marginalis is known only from the type collection, and is characterized as follows: culms robust,
generally about twice as thick as in A. gibbosa or A. sorzogonensis, branching above the base, with numerous
(7-8) nodes elevated above the base; sheaths short, about Y the length of the internode, straw-colored and
contrasting with the pale greenish internode; blades flat, curling, with thickened margins, pilose on the
adaxial surface; panicles narrow, but weakly pulvinate.
Distribution —Known only from Brazil: Matto Grosso, Cuiba (Fig. 18).
The name Aristida marginalis has been applied to similar plants from North America, many of which

are conspicuously pulvinate, particularly collections reported as such by Howard Scott Gentry (1942) from
the Rio Mayo region in western Chihuahua. All of these North American plants fall well within the A. sor-
zogonensis cluster on the PCA, and differ from the true Brazilian A. marginalis in the features given in the key.
Further field and herbarium work are needed to fully explain the distribution and variation of Aristida
marginalis. Its apparent int liacy between A. gibbosa and A. sorzogonensis seems coincidental, and not a
result of hybridization or introgression. As with many species of Aristida, species boundaries are likely to
be delicate, yet decipherable, and the name should not be discarded as inconsequential.

Bromus L. is a large and t ically complex grass g that includ than 160 species distributed
in temperate regions worldwide. The, genus is distinguished from other grass genera by the combination of
leat sheaths that are closed for most of their length, awns that are inserted subapically and hairy append-
ages on the apices of the ovary (Clayton & Renvoize 1986). Approximately 80 Bromus species are currently
recognized in North, Central and South America (Pavlick et al. 2003): 29 of these reportedly occur in Canada
(Pavlick & Anderton 2007). Among the 10 Canadian provinces and three territories (Fig. 1), the western-
most and topographically diverse British Columbia has the greatest number of Bromus species. Bromus is
the second-largest grass genus in British Columbia; only Poa L., with 31 species (Soreng 2007), has greater
species richness in the province.
In North America most workers recognize five sections in Bromus (reviewed by Saarela et al. 2007),
but multiple recent molecular phylogenetic studies indicate that not all are natural groups, particularly the
globally widespread B. sect. Bromopsis Dumort., which appears to comprise distinct Sierra Madrean (Mexi-
can), North American, South American and Eurasian lineages (e. g., Pillay & Hilu 1990, 1995; Saarela et al.
2007). More work is needed to clarify higher-level phylogenetic relationships in Bromus. Nonetheless, the
traditionally recognized Bromus sections can generally be recognized morphologically and learning their
key characteristics can greatly aid in species identification in the field and herbarium.
There has been considerable progress in clarifying lower-level taxonomic problems in Bromus. Several
species that occur in North American have received recent taxonomic study, including; B. ciliatus L. and B.
richardsonii Link (Peterson et al. 2002); B. grandis (Shear) Hitchc., B. hallii (Hitchc.) Saarela Er P.M. Peterson
and B. orcuttianus Vasey (Saarela et al. 2005); Bromus catharticus var. elata (E. Desv.) Planchuelo (Planchuelo
2006); and B. carinatus Hook. & Arn. (Barkworth et al. 2006). Similar recent taxonomic work has been con-
ducted on taxa from South America (Massa et al. 2001, 2004; Saarela et al. 2006) and Eurasia (Sales 1993,
1994; Spalton 2002). Comprehensive taxonomic treatments of Bromus for North America north of Mexico

a detailed and updated taxonomic treatment for Bromus in British Columbia, including a dichotomous key,
synonymies, species descriptions, distribution maps and citations of representative specimens.
Bromus in British Columbia
Bromus in British Columbia includes multiple native and introduced species that are currently classified in
four sections. Most of the introduced species are annuals classified in B. sects. Bromus (B. briziformis Fisch.
Sr C.A. Mey., B. commutatus L., B. hordeaceus L., B. japonicus Thunb., B. racemosus L., B. secalinus L. and B.
squarrosus L.) and Genea Dumort. (B. diandrus Roth, B. sterilis L. and B. tectorum L.). All of these (and other)
introduced species in B. sects. Bromus and Genea occur throughout western North America, mostly north
of Mexico (see Pavlick & Anderton 2007; Saarela & Peterson in press), and several have caused serious eco-
logical disruption. In general, annual species can be distinguished from perennial species based on basal
vegetative characteristics. In perennial B species, the dried remains of the previous years’ growth are
normally present, whereas there is no previous years’ growth in the annual species. In most cases the annual
taxa are generally smaller in stature and have a more delicate appearance (with some exceptions, such as
some individuals of the large annual, B. diandrus), compared to the perennial taxa. Bromus sect. Bromus is
characterized by 3-5-nerved first glumes, 5-7-nerved second glumes and lemmas rounded over the backs,
Saarela, Bromus in British Columbia, Canada 325
whereas B. sect. Genea is characterized by 1(-3)-nerved first glumes, 3(—5)-nerved second glumes and nar-
row, elongate lemmas. Species of B. sect. Bromopsis in British Columbia are perennials with 1(-3)-nerved
first glumes, 3(-5)-nerved second glumes and lemmas rounded or slightly keeled over the backs (i.e., flat-
tened dorsiventrally). Two B. sect. Bromopsis species in British Columbia are introduced: the highly invasive
smooth brome (B. inermis Leyss.) and meadow brome (B. riparius Rehm.), which is reported here as part of
the British Columbia flora for the first time. The remaining five B. sect. Bromopsis species in the province
are native: B. ciliatus L., B. pacificus Shear, B. pumpellianus Scribn., B. richardsonii Link and B. vulgaris (Hook.)
Shear. The remainder of the Bromus taxa in British Columbia are classified in B. sect. Ceratochloa (P. Beauv.)
Griseb., a group that is widespread throughout the province and easily recognizable on the basis of its
strongly laterally flattened and keeled glumes and lemmas. Species limits within B. sect. Ceratochloa are
not clear, both in ind Columbia and more o d throughout western North America. Taxa in B. sect.
Ceratochloa variously reco gnized at different ranks; in British Columbia these include B. aleutensis
Trin. ex Griseb. [-B. sitchensis Bongard var. aleutensis (Trin. ex Griseb.) Hultén], B. carinatus Hook. & Arn.,
B. marginatus Steud. [=B. carinatus var. marginatus (Nees.) Barkworth & Anderton], B. polyanthus Scribn. ex
Shear and B. sitchensis Bongard (e.g., Calder & Taylor 1968; Hitchcock et al. 1969; Hubbard 1969; Pavlick
1995; Douglas et al. 2001; Clayton et al. 2002 onwards; Barkworth et al. 2006; Pavlick & Anderton 2007).
Because taxon circumscriptions are not clear in B. section Ceratochloa, the section is not treated here (al-
though it is included in the key).

names that have been applied to the introduced taxa in their native European ranges (i.e., species of B. sects.
Bromus and Genea); these names are rarely used in the North American literature. Information on common

Distribution and Habitat. — Introduced. Bromus briziformis is native to Eurasia. In British Columbia it is
known only from a handful of populations near the Canada/ U.S.A. border (Fig. 3A). It has been collected
in the northwestern United States and in a few scattered locations in central and eastern North America
(Pavlick & Anderton 2007). Habitats include waste places, roadsides and other disturbed areas. Elevation:
600-914 m.
Common Names.—rattlesnake brome, rattlesnake bromegrass, rattlesnake chess, rattlegrass.
Notes.—Bromus briziformis is an annual species that superficially resembles the quaking grasses (Briza
L.; the introduced B. major and B. minor are reported from British Columbia), but it is easily distinguished

Distribution and Habitat.—Native. Bromus ciliatus is the widest-ranging native B. sect B psis species
in North America. lt occurs across the continent, absent only in south-central and south-eastern U.S.A.
(Pavlick & Anderton 2007). Bromus ciliatus occurs throughout British Columbia, mostly east of the coastal
mountain ranges (Fig. 3B). Its distribution is P with that of B. richardsonii, but B. ciliatus generally
occurs at lower elevations (Peterson et al. 2002). B s ciliatus occurs in a wide range of habitats, including
wet ditches, roadsides, boggy areas, dry terraces, moist woodlands, forest openings, stream banks, rocky
flats and grassy areas. Elevation: 396-1554 m.
Common Names.—English: fringed brome; French: brome cilié.
Notes.—Bromus ciliatus and B. richardsonii have been variously treated as the same or r separate taxa (see
comments under B. richardsonii). Peterson et al. (2002) d trated that tl lly and
L e +
genetically distinct and appropriately recognized at the species level. Because B. ciliat in a variety of
habitats, there is interest, particularly in western Canada, for developing ecological adavan for re-seeding
disturbed areas and clearcuts (see May et al. 1998, 1999; Fu et al. 2005). Fu et al, (2005) used AFLP data
to examine molecular variation within and among B. ciliatus populations across Canada and found high
among-population variation and low within-population variation.

Distribution and Habitat. — Introduced. Bromus tatus is native to Europe. It is common in eastern
and western North America and occurs in scattered locations across the United States Great Plains (Pavlick
& Anderton 2007). In British Columbia, B. commutatus occurs in the southern portion of the province (Fig.
3C). Habitats include waste places, fields and grasslands. Elevation: 0-967 m.
Common Names.—English: hairy brome, hairy chess, meadow brome, upright chess; French: brome
variable, brome confondu.
Notes.—Bromus commutatus and B. hologicall il ies t] f
difficult to distinguish. They are both native to Europe, bur now SE) more del distributed. Hess
& Chase (1951:49) noted that these taxa are "differentiated only by arbitrary characters.” In his classifica-
tion of subgenus Bromus (=B. sect. Bromus), Scholz (1970) placed B. commutatus and B. racemosus in different
series, and many authors recognize them as separate species (e.g., Clapham et al. 1987; Conert 1997; Smith

1980, 1985; Stace 1997; Douglas et al. 2001; Pavlick & Anderton 2007; Saarela & Peterson in press), but
others have treated B. commutatus as a subspecies of B. racemosus (e.g., Shear 1900; Acedo & Llamas 1999;
Lauber & Wagner 1996; Meijden 1996) or at least suggested that this treatment might be appropriate (e.g.,
Pavlick 1995; Planchuelo & Peterson 2000). Some workers lump these taxa and recognize only a single,
variable species (e.g., Liang et al. 2006). Acedo & Llamas (1999) noted substantial phological variation
among these taxa in the Iberian Peninsula, and indicated that environmental conditions influence plant
and inflorescence size.
In most treatments, B. commutatus is circumscribed as having longer lemmas (8-11 mm vs. 6.5-8 mm
in B. racemosus), broadly angled lemma margins (vs. rounded) and shorter anthers (but measurements in
earlier keys vary substantially) [reviewed by Spalton 2002]. Additionally, B. commutatus is generally con-
sidered to have more open panicles with longer branches that sometimes have more than one spikelet (vs.
less open panicles with shorter branches usually with a single spikelet), but these characters have not often
been used in keys. Spalton (2002) conducted a morphological analysis of B. racemosus, B. commutatus and
E Rap a a B. secalinus, jdn on material from throughout their native ranges. He
overlap i liy used to distinguish B. racemosus and B. commutatus
(e.g., lemma length) and found that the single best diagnostic character to distinguish the taxa is the length
of the lowest panicle branches (including the terminal spikelet) (i.e., > 4 cm long in B. commutatus vs. < 4
cm long in B. racemosus). Consequently, Spalton’s (2002) circumscriptions of B. commutatus and B. racemosus
are slightly different from those employed by earlier authors, but his work is also the most comprehensive
study of variation in the complex. Spalton (2002) conc luded that B. commutatus is distinguished by its larger,
more open and often branched inflorescences and larger spikelets, and B. racemosus is distinguished by its
narrower, unbranched inflorescences and smaller spikelets. Using these characters, most British Columbia
individuals can be readily placed into one of these two taxa. My observations of material from British Co-
lly more robust, usually with some
lumbia indicate that plants with long
branches that have more than one spikelet and larger spikelets. 1 M Spalton’s circumscription here and
recognize B. commutatus and B. racemosus at the species level, as in most recent treatments of these taxa in
North America and Europe. I have ol 1 mixed populations of B. commutatus and B. racemosus in British
Columbia near Princeton [Saarela, Sears & Maze 586A (CAN, UBC), 586B (CAN)] and Elko [Saarela 405A
(CAN, UBC), 405B (CAN)]. A comprehensive genetic study of this complex, ideally based on material from
throughout their native ranges, would contribute to e the natural boundaries between these taxa.

Distribution and Habitat. —Introduced. Bromus diandrus is native to Europe. In North Geer itis com-
mon in the west from Washington to California and Texas, with ttered localities in tl
United States (Pavlick & Anderton 2007). In British Columbia the species occurs on southern Vancouver
Island and in the Vancouver area (Fig. 5A), where it is distributed in waste places, roadsides, thickets, river
banks, sand bars, rocky outcrops, grassy banks and disturbed ground. Elevation: 0—290 m.
Saarela, Bromus in British Columbia, Canada 335
Common Names.—ripgut brome, ripgut grass.
Notes.—In British Columbia (Douglas et al. 2001) and elsewhere in western North America, this intro-
duced taxon has previously been treated as B. rigidus Roth. Sales (1993) conducted a comprehensive survey
of morphological, geographical and ecological variation in the Bromus diandrus/ rigidus complex based on
material collected throughout its native European range, and recognized these taxa as varieties: B. EE
var. diandrus and B. diandrus var. rigidus (Roth) Sales. However, Sales (1993) noted that the diff
her varieties are very subtle and that it is often very difficult to one variety or the other.
I therefore treat all British Columbia material as B. diandrus s. L witha no recognition of intraspecific taxa, as
in the recent Bromus treatment for North America by Pavlick and Anderton (2007) and that forthcoming for
California (Saarela & Peterson in press). Bromus diandrus has the largest spikelet characters (glumes, lem-
mas, awns) among the three B. sect. Genea species in British Columbia; consequently, it is straightforward
to identify.

Distribution and Habitat. —Introduced. Bromus hordeaceus is thought to be native to the Meditteranean
basin (Smith 1986). It is now distributed widely in North America (Pavlick & Anderton 2007), Europe, Africa
and Australia. In British Columbia B. hordeaceus occurs throughout the southern portion of the province
and on the Queen Charlotte Islands (Fig. 5B). It is distributed in waste places, roadsides, fields, grassy areas
and sandy beaches. Elevation: 0-1110 m.
Common Names.—English: soft chess, soft brome-grass, soft cheat, tender brome-grass, soft-brome, soft
brome; French: brome mou, brome doux, brome mollet.
Notes.—Bromus hordeaceus can be very difficult to distinguish from B. racemosus, even with considerable
experience. These taxa have been lumped E some workers, reflecting Hus EE e B^ Wilken & Painter
1995), but most workers recognize both taxa. Their major di degree of lemma
nerve protrusion. In B. hordeaceus, the lemma nerves are id and M (Fig. 7B), whereas in B.
racemosus the lemmas are smooth, with nerves raised Ld or not at A Fig 7A). This dnd is usually
most easily observed near the apex of the lemma. B tend d
compared with B. racemosus, but there is variation in this character and it is not always reliable.
Bromus hordeaceus is a morphologically variable species (Fig. 6). In Europe, most workers recognize
several intraspecific taxa (as subspecies) in the complex, differentiated by lemma length, awn width at its
base, awn curvature, culm height and spikelet pubescence (e.g., Smith 1968, 1980, 1985; Zajac 1996).
These subspecies are generally difficult to tell apart, but they have been recognized in recent treatments
for North America (e.g., Pavlick 1995; Pavlick & Anderton 2007). Two subspecies [subsp. hordeaceus and
subsp. thominei (Hardham ex Nyman) Braun-Blanquet] were recognized in British Columbia by Douglas
et al. 2001). Douglas et al. (2001) also indicated that the putative hybrid B. x pseudothominei P.M. Sm. (B.
hordeaceus subsp. hordeaceus x B. lepidus Holmberg) is infrequent on southern Vancouver Island.
In material of the B. hordeaceus plex from British Columbia, I have observed that many individuals
have a combination of the morphological characters typically used in keys to distinguish the subspecies,
and they cannot be reliably differentiated. Specimens of the putative hybrid are also indistinguishable from
other B. Nee EE SE et al. (1996, oai found no Moda of DNA sequence or al-

traditionally used to segregate intraspecific taxa among populations they examined. Intraspecific taxa in
this group in North America are not recognized here.

Saarela, Bromus in British Columbia, Canada 341
Distribution and Habitat.—Introduced. Bromus inermis is native across central Eurasia, and introduced
in Africa, Australia, North America and South America. It is distributed widely across North America and
it is extremely common (Pavlick & Anderton 2007). Bromus inermis has been collected throughout British
Columbia, mostly on southern Vancouver Island, in the Vancouver area and east of the coastal ranges (Fig.
5C; also see Othnowski et al. 2007:188). Habitats include roadsides, fields and pastures, wet ] and
open woods. Elevation: 0-1256 m.
Common Names.—English: Austrian brome, Austrian brome grass, awnless brome, awnless brome
grass, Hungarian brome, Hungarian brome grass, Hungarian fodder grass, Russian brome, smooth brome,
smooth brome grass; French: brome inerme, brome de HORES brome sans arétes
Notes.—The introduced B. inermis and the native B. pum] ly
(e.g., Elliott 1949; Wagnon 1952; Scoggan 1978) or ani species (e.g., Pavlick 1995; Pavlick & Ander-
ton 2007). Elliott (1949) demonstrated that the taxa are partially interfertile and presented morphological
evidence (i.e., intermediate specimens) indicating that hybridization has likely occurred between the taxa.
Nevertheless, the taxa have different morphological characteristics and native distributions and they occur
in different habitats, suggesting that they have independent evolutionary histories. Bromus inermis is also
morphologically similar to the relatively recently introduced B. riparius (see discussion under that taxon).
Bromus inermis was introduced into North America in 1884 by the California Agricultural Experi-
mental Station. In Canada it is widely cultivated for hay and pasture and used in revegetation projects, but
although economically beneficial as forage, B. inermis is extremely invasive and poses serious threats to
Canadian ecosystems (Otfinowski et al. 2007). It was recently ranked as the 8'^ most serious invasive alien
plant threatening natural habitats in Canada (Catling & Mitrow 2005). Otfinowski et al. (2007) provide a
detailed review of the biology of Bromus inermis.

Distribution and Habitat.—Introduced. Bromus japonicus is native to Europe. In North America, B.
japonicus is distributed widely throughout the U.S.A. and in southern Canada (Pavlick & Anderton 2007).
Bromus japonicus has been collected in various places throughout British Columbia; it is most common in
the interior of the province (Fig. 9A). Habitats include roadsides, grassy areas, hillsides and meadows. El-
evation: 152-1050 m. Whisenant (1990) suggested that B. japonicus has become problematic in areas that
have reduced occurrence of fire and grazing by large animals.
Common Names.—English: Japanese chess, Japanese bromegrass, Japanese brome, spreading brome;
French: brome du Japon, brome japonais.
Notes.—The authority for this name has been variously attributed to ‘Thunberg’, ‘Thunberg ex Mur-
ray’, ‘Thunberg in Murray’, and ‘Murray’, because it was published in both Flora Japonica (Thunberg, 1784,
August) and Systema Vegetabilum, ed. 14 (Murray 1784, May-June), being attributed to Thunberg in the latter.
Because of this confusion, Bartholomew et al. (Taxon 46:311-314. 1997) considered the author citations of
the many new names published in these works and concluded that their authorship should be attributed
to ‘Thunberg in Murray’ when a complete bibliographic citation is given (as above), or as ‘Thunberg’ when
only me aon is E
CES T CE ished on the basis of their
Kee lemma EE vith and E degree of ade branching (see Savoie Key). Some individuals
wit be difficult to determine, but the taxa have consistently been
— a as dista species in eine native and introduced ranges. Molecular (Ainouche & Bayer 1997,
Ainouche et al. 1999) and serological data (Smith 1972) indicate that they are closely related. Based on al-
lozyme and morphometric data, Oja et al. (2003) suggested that the two taxa might be more appropriately
recognized as intraspecific taxa of a single polymorphic species. Oja et al. (2003) did not, however, propose
a formal taxonomic revision of the group. I recognize these taxa here at the species level.

eastern Alaska to central Oregon (Pavlick & Anderton 2007). Pavlik & Anderton (2007) indicated that B.
pacificus also occurs in northern California, based on two specimen s from HSC identified as B. pacificus (M.
Barkworth, pers. comm.). Examination of these specimens indicates that they were incorrectly determined
[Barker 1035 (HSC-44691!) from Del Norte Co. is B. vulgaris; and Anderson 5120 (HSC-22840!) from Hum-
boldt Co. is B. carinatus Hook. & Arn. var. marginatus (Nees) Barkworth & Anderton]. Bromus pacificus is
not known from California (Saarela & Peterson, in press). In British Columbia, B. pacificus occurs in coastal
regions of the province (Fig. 9B); absence of collections along much of the coastline likely reflects a paucity
of collecting activities in difficult-to-access areas, rather than the absence of the species. Habitats include
moist ravines, shaded woods, grassy swards, saline beaches, ditches and along roadsides. Elevation: 0—50
m.
Common Names.—Pacific brome, Shear Pacific brome.
Notes.—Many B. pacificus specimens from British Columbia have previously been determined incor-
rectly as species of B. sect. Ceratochloa (i.e., B. carinatus or B. sitchensis). With large, open panicles, B. pacificus
is superficially similar to these taxa, but it can be easily distinguished from them by its lemmas that are
rounded or slightly keeled over the back (vs. lemmas that are strongly laterally flattened and keeled in spe-
cies of B. sect. Ceratochloa), and 1- and 3-nerved lower and upper glumes (vs. 3-5- and 5-9-nerved lower
and upper glumes, respectively). Additionally, B. pacificus occurs only on or near the coast, whereas plants
in B. sect. Ceratochloa are distributed much more widely.

Distribution and Habitat. — Native. B teri in sout hern Alberta, Saskatcl and Manitoba
and south to western Texas and California (Pavlick & Anderton 2007). In British Columbia B. porteri occurs
mostly in the interior of the province. Habitat includes dry talus slopes, meadows, open ground, woodland
flats and grasslands. Elevation: 152-1310 m.
Common Name. — nodding brome.
Notes.—Bromus porteri has been variously treated as a distinct species (e.g., Gould & Moran 1981;
Pavlick 1995; Pavlick & Anderton 2007; Scoggan 1978; Soderstrom & Beaman 1968) or as a synonym of
Bromus anomalus Rupr. ex E. Fourn. (e.g., Douglas et al. 2001; Wilken & Painter 1993). Bromus anomalus and
B. porteri are morphologically and geographically distinct taxa. Bromus anomalus is easily separated from
B. porteri by its 1-nerved lower glumes [vs. (1)3-nerved in B. porteri] and conspicuously narrowed midvein
of the leaf below the collar (Wagnon 1952; Pavlick 1995; Pavlick & Anderton 2007, J. M. Saarela, personal
observation). The two species are largely allopatric. B teri has a wide distribution in western North
America where it is distributed from Manitoba to British Columbia and south to California, New Mexico
and northeastern Mexico (Wagnon 1952; Pavlick 1995; Herrera Arrieta 2001; Pavlick & Anderton 2007;
Saarela & Peterson in press), whereas B. anomalus is distributed in Texas and throughout northern and cen-
tral Mexico (Soderstrom & Beaman 1968; Pavlick et al. 2003; Herrera Arrieta 2001; J. M. Saarela, personal
observation). Plants in British Columbia are clearly referable to Bromus porteri.

Distribution and Habitat—Introduced. In North America, B. racemosus occurs in scattered locations
across the S.A. e southern Canada (Pavlick & EE ZOON In British Columbia B. racemosus occurs
mostly in t tern and southcentral parts of the province (Fig. 12B). Habitats include waste places,
field, roadsides and gravelly hillsides. Elevation: 0-967 m
Common Names.—bald brome, meadow brome, smooth brome, smooth chess.
Notes. —Bromus racemosus is often confused with Bromus hordeaceus because both taxa have relatively
narrow inflorescences, and the two have sometimes been treated as synonyms (e.g., Wilken and Painter
1993). Bromus hordeaceus is distinguished by its lemmas with conspicuously raised nerves and generally
denser inflorescences. See additional comments under B. commutatus and B. hordeaceus.

Common Name.—Richardson's brome.
Notes.—Bromus richardsonii has been variously recognized as a distinct species (Shear 1900; Hitchcock
1913; Wagnon 1952; Mitchell & Wilton 1965; Mitchell 1967; Hultén 1968; Welsh 1974; Pavlick 1995; Herrera
Arrieta 2001; Peterson et al. 2002; Saarela et al. 2005; Pavlick & Anderton 2007; Saarela and Peterson, in
press), as a synonym of B. ciliatus (e.g., Allred 1993; Hitchcock 1951; Soderstrom & Beaman 1968; Wilken
& Painter 1993; Douglas et al. 2001) or as a variety of B. ciliatus (e.g., Kartesz 1999). In a detailed study of
the complex, Peterson et al. (2002) identified distinctive morphological, cytological and genetic differences
that support recognition of these taxa as distinct species (see Taxonomic Key).

Distribution and Habitat.—Introduced. Grassy meadows, pastures. Bromus riparius is known only from
a single collection along Highway 3 in southeastern British Columbia (Fig. 13A). It is promoted in western
North America for forage, but its precise distribution is not clear (Pavlick & Anderton 2007). See additional
notes below.
Common Name.—English: meadow brome; French: brome des prés.
Notes.—Meadow brome (Bromus riparius) is native to southeastern Europe, Turkey, the Caucasus and
central Asia. It was introduced into North America in the last century as a potential forage crop. A cultivar
(Regar selected from material collected in Turkey was registered in the United States in 1966 and in Can-
ada in 1980 (de Araújo & Coulman 2004). Bromus riparius is now promoted and grown widely for forage
across western Canada and in adjacent regions of the U.S.A. There is substantial interest in this grass in the
agronomic community and several cultivars (Fleet, ‘Paddock’, ‘Cash’ and ‘Montana’) have recently been
developed (Knowles 1990a, b; Cash et al. 2002; Jensen et al. 2004). From its first release, the name applied
(incorrectly) to meadow brome in the United States was B. biebersteinii Roem. & Schult., a name that is still
widely used in many government agronomy publications and in the seed trade. Bromus biebersteinii is a
Mid ded SENG AC NA (EIS ae 1976) that is not reported for North America.
lly similar and closely related (Saarela et al. 2007) to B. inermis (smooth
iom. see EE ee introduced species widely used for forage and hay, which is seriously invasive
in native plant communities (Otfinowski et al. 2007). Smooth bromegrass is widely grown because it is
drought-tolerant and sod-forming, but it has slow regrowth characteristics and is considered better suited
for use as hay. Meadow brome has better re-growth characteristics and is thus considered better suited for
forage in pasture conditions (e.g., Thompson et al. 2003). Several reports indicate that B. riparius is less

aggressive than B. inermis and not invasive (Anonymous 2000; de Araújo 2001; Ogle et al. 2004). Through
da PEN two i iin EE have been developed and selected by Agriculture and Agri-Food
anada: g from a B. inermis and B. riparius (Knowles”, Coulman 2004), the other
originating Doni a B. inermis x B. riparius hybrid backcrossed with B. inermis (Success”, Coulman 2006). These
hybrids combine characteristics of each of their parents; they are.considered suitable for use as both hay and
pasture (Knowles & Baron 1990; Knowles et al. 1993; Coulman 2004, 2006). Because of their agricultural
importance, numerous aspects of morphology, forage quality and genetic diversity have been characterized
in B. inermis, B. riparius, and their hybrids (e.g., Ferdinandez and Coulman 2000, 2001, 2002; Ferdinandez
et al. 2001; de Araújo & Coulman 2004). There are no reports of B. riparius being adventive in Canada.
Bromus riparius was treated in the Flora of North America (Pavlick & Anderton 2007). It was included
there shortly before the volume went to press, but a detailed distribution map for the taxon was not available.
In Canada, Bromus riparius is recognized as part of the flora in Saskatchewan (determined incorrectly as B.
biebersteinii Roem. & Schult.; Harms 2006). Almost certainly it is present in Alberta, and a recent collec-
tion from Manitoba is cited below. It has not yet been reported for British Columbia. There is no mention
of B. riparius (or B. biebersteinii) in recent treatments of the British Columbia flora (Qian & Klinka 1998;
Douglas et al. 2001), nor in Pavlick's (1995) treatment of Bromus in North America. In May 2006 I collected
B. riparius in southeastern British Columbia in a fenced-in meadow at a rest stop along Hwy 3 [Saarela 417
(CAN, UBC)]; this collection apparently represents the first record of the species in the province. Indeed,
the species has been grown in field trials in British Columbia (e.g., at Devick near Kamloops; May et al.
1999). and cultivars of B. riparius are EU S p in oa Columbia and used for amelioration S.

may have been deliberately planted here as De or it may la been introduced by road traffic. Sg of B.
riparius is sometimes found as a contaminant in smooth brome seed commodities (Allison et al. 2001; SJ.
Darbyshire, pers. comm. March 2007). Whatever the source of the introduction, Bromus riparius should be
recognized as a component of the British Columbia flora, and additional occurrences for this species should
be looked for.
The morphological description is based on my field collections from British Columbia and Manitoba, as
354 tani i Texas 2(
well as several specimens of cultivated plants (mostly greenhouse grown at the Agriculture and Agri-Food
Canada Central Experimental Farm in Ottawa, Ontario, Canada) in DAO. Some of this cultivated material
represents the cultivars ‘Fleet? ‘Paddock’ and ‘Regar’, differentiating morphologically among these and the
other cultivars was beyond the scope of this study. Bromus riparius is one of three Bromus species in British
Columbia (including B. inermis and B. pumpellianus) with rhizomes and long anthers (usually > 4 mm), and
it therefore is relatively straight forward to identify. These three species are members of an Old World al-
liance of taxa (B. pumpellianus is the only native species in North America that is part of this group) whose
evolutionary relationships with other North American perennial Bromus species are not yet clear (Saarela et
al. 2007). Because B. riparius is a relatively recent addition to the New World flora, there is little information
in the North American botanical taxonomic literature for the species.
There are several morphological characters that distinguish Bromus riparius. In an effort to identify
characteristics to help seed analysts distinguish florets of B. inermis and B. riparius, which are sometimes
mixed in seed commodities, Allison et al. (2001) conducted a careful study of the floret morphology of these
taxa and found useful variation in the cilia (described by them as ‘siliceous prickle hairs’) on the palea keels.
In B. riparius, cilia on the palea keels are present only distally, whereas in B. inermis cilia are present on the
keels along the entire palea length. Figures 1-4 and 9 in Allison et al. (2001) illustrate this cl ter clearly.
Allison et al. (2001) did not examine this character for B. pumpellianus. In B. pumpellianus cilia are present
along the entire length of the palea keels, like in B. inermis, or only along the lower 34. Bromus riparius is
further distinguished by its longer awns, which are (3-)4-7.1 mm long [vs. 0-3 mm long in B. inermis and
1-4 mm long in B. pumpellianus]. Several vegetative characters are also useful in distinguishing the three
species. Leaf blade margins of B. riparius are characterized by the presence of long, stiff hairs (to 2.5 mm
long) that are conspicuously wider at their base (Fig. 14); such robust hairs do not occur in B. inermis and B.
pumpellianus. In his keys to Bromus in the (former) U.S.S.R., Tzvelev (1976) distinguished B. riparius from B.
inermis and B. pumpellianus by the degree of shredding of basal leaf sheaths. Examination of this character
in Canadian material confirms that it is very useful for distinguishing B. riparius from the other two taxa.
The basal sheaths of decaying leaves in B. riparius are reticulate-fibrillose (i.e., they have a ‘thatched’ ap-
pearance), the readily decaying basal sheaths in B. pumpellianus are split into straight fibers and the basal
sheaths of B. inermis, which do not appear to decay as readily as those in B. pumpellianus or B. riparius, also
split into straight fibers (Fig. 15). Pavlick & Anderton (2007) distinguished B. riparius from B. inermis and B.
pumpellianus based on culm height and rhizome length; they noted that time constraints did not allow them
to fully clarify its similarities and differences with these other taxa. Bromus riparius is weakly rhizomatous,
B. pumpellianus is moderately so and B. inermis is strongly rhizomatous. Pavlick & Anderton (2007) also
noted that it is not clear how B. riparius differs from B. pumpellianus subsp. dicksonii W. W. Mitch. & Wilton,
a taxon known only from the Yukon River drainage in northwestern North America (Yukon and Alaska);
characterization of differences between these two taxa was beyond the scope of this study.

Distribution and Habitat.—Introduced. Bromus squarrosus var. squarrosus is native to Eurasia (Izvelev
1976). In North America it occurs across the Great Plains in the northern U.S.A., around the Great Lakes
area and in other scattered locations (Pavlick & Anderton 2007). In British Columbia it is most common
in the interior and in the Columbia basin (Fig. 13C). Habitats include grasslands, hillsides, disturbed areas
and roadsides. Elevation: 311-823 m
Common Names.—corn brome, downy brome, field brome, nodding brome, one-way brome.

Similar to var. squarrosus, but glumes and lemmas densely pubescent with hairs to 0.8 mm long.
Distribution and Habitat — In North America B. squarrosus var. villosus is only known from the three
southern British Columbia collections cited below. Additional occurrences in North America should be
searched for in the field and in herbaria. Tzvelev (1976:335) indicated that, in its native range, the variety
is somewhat rarer in distribution than the typical variety.
Notes.—Nomenclature used here follows Kerguélen (1999). Bromus squarrosus var. vi
reported here for the first time for continental North America. Material examined from British Columbia
closely matches material seen from Russia le.g., Skvortsov s.n. (CAN-578016) collected in Volgograd]. The
description for B. squarrosus by Pavlick (1995) and Pavlick & Anderton (2007) does not mention the presence
of dense pubescence in the taxon, which suggests that these authors did not observe pubescent forms of
the species. The 1993 record from British Columbia was collected by Pavlick, but this was likely long after
he completed work on his revision of Bromus for North America (Pavlick 1995).

Distribution and Habitat.—Introduced. Bromus sterilis is native to Europe, northern Africa and south-
western Asia (Sales 1993). In North America it occurs in western and eastern North America (Pavlick &
Anderton 2007). In British Columbia B. sterilis occurs only in the extreme southwest of the province in the
Vancouver area and on central to southern Vancouver Island (Fig. 19A). Habitats include roadsides, sandy
beaches, meadows and waste places. Elevation: 0-425 m.
Common Names.—barren brome, poverty brome.
Notes.—Several intraspecific taxa that have been previously recognized are mentioned by Sales
(1993:5-6), but she did not recognize these; none have been recognized in the North American flora.

Distribution and Habitat.—Introduced. Bromus tectorum is widespread across the United States and
southern Canada, with scattered collections from locations in Alaska, Yukon and the western Northwest
Territories (Pavlick & Anderton 2007; Valliant et al. 2007). The species is most common in the southern
half of the province and it has been collected sporadically in northwestern British Columbia [Fig. 19B; see
Valliant et al. (2007) for another recent distribution map]. Habitats include roadsides, fields, meadows, arid
slopes, woodlands, cliffs and talus slopes, hillsides, dry rangeland, pastures, sandy beaches, railroad tracks
and other waste places. Elevation: 0—1800 m.
Common Names.—English: cheatgrass, cheat grass, downy brome, drooping brome, early chess, military
e e
grass, thatch bium duds EE SE des toits, brome des murs.

Distribution and Habitat. — Native. In North America, B. vulgaris o in British Columbia, soutl
PONO and da to western Wyoming and south-central California (Pavlick & Anderton 2007). Bromus
t the southern half of British Columbia (Fig. 19C). It was only recently reported from
Wio erby Island (Queer Charlotte Islands; Lomer & Douglas 1999) A SE collection [Saarela & Percy 1169
(CAN, UBC)] represents the first record of B. vulgaris from tl ] Island. Habitats include
moist woods, stream banks, damp thickets, along trails, meadows and rody banks. Elevation 0-2286 m.
Common Names.—Columbia brome, narrow-flowered brome, common brome.
Notes.—In herbarium material of B. vulgaris, leaf blades tend to appear conspicuously thin and papery
compared to those in other species of B. sect. Bromopsis, though it is difficult to adequately describe this
qualitative characteristic. This characteristic does not seem to be as evident in the field. At present, there
are no leaf blade anatomical data for North American B. sect. Bromopsis species which might allow further
evaluation of this character.

Notes on Excluded Species
There is a single, early collection of B. arvensis L. (field brome) from British Columbia [Invermere, 29 Jul 1915,
M.O. Malte 108375 (CAN!, DAOU) In his distribution maps, Pavlick (1995) indicated that B. arvensis occurs
in British Columbia, probably based on this collection. The annual B. arvensis, a species classified in B. sect.
Bromus, is native to Europe; it occurs in scattered locations across North EE more commonly in the
eastern U.S.A. (Pavlick & Anderton 2007). It is not known if B. o i ists in British Columbia;
it therefore is not formally treated here. Should the species be collected SECH in Bh Columbia, it can be
distinguished from other B. sect. Bromus species in the province as follows: anthers 2.5—5 mm [vs. anthers
< 2.53) mm]; linear-lanceolate spikelets that narrow only slightly towards their apex [vs. ovate-lanceolate
spikelets that narrow conspicuously towards their apex]; lower leaf sheaths with dense, softly appressed
hairs 0.4—0.6 mm long [vs. lower leaf sheaths glabrous, sparsely to densely pilose with stiff hairs 0.5-0.6
mm long, or with soft and wavy hairs to 1.2 mm long]; and often purple-tinged spikelets (this colouration
is not always present in dried specimens).
Taylor and Macbride (1977) reported B. rubens L. [=B. madritensis subsp. rubens (L.) Husn.] from Brit-
ish Columbia. Following this report, Salo (2005) indicated that red brome occurs in British Columbia, but
she did not include any specimens on her distribution maps. There is a single collection of this species
from British Columbia, collected over a century ago (Nanaimo, Vancouver Island, 13 Jul 1893, Macoun 118
CAN-39043!, photo: DAO-56101!). The species seems not to have persisted in British Columbia and it is
therefore not treated here.
Scoggan (1978:252) noted that B. orcuttianus Vasey had been previously reported from near Victoria,
Vancouver Island. Bromus orcuttianus does not occur in British Columbia (see Saarela et al. 2005).

which are very distinct from the g ME E and Pseudoxytenanthera.
Therefore. we are erecting a new genus to accommodate the species.
It was Colonel Munro (1868) who first described the new species in his monograph on Bambusa.
Bambusa ritcheyi, was based on a herbarium specimen collected by J.C. Ritchie from Kala Nuddi, Bombay,
India. In the addenda of the same publication, Munro corrected the spelling of the ritcheyi to 'ritchiei'
to commemorate Ritchie's name. After a lapse of five years Beddome (1873) collected this bamboo from
Anamalai and included it under the genus Oxytenanthera Munro. Due to the presence of a monostigmatic
ovary, Beddome named this species as Oxytenanthera monostigma. This species was subsequently reported
by various workers from Western Ghats, hills of south west India from Ra NE to Anamalai up to
Palakkad gap such as Brandis from Sattara Ghats in 1870; R.S. Fagan at Mahabalesl in 1892; WA. Talbot
from North Canara in 1884 and 1889; R.C. Wroghton, from Pune district and A.D. Wilkins from Ahamed
Nagar in 1892 (Gamble 1896). Gamble stated that Munro himself had also agreed with the new treatment
as Oxytenanthera monostigma. Later, Brandis (1906) and Bourdillon (1908) followed this treatment. Gamble,
noted that the species has very well-marked velvety culms, a narrow culm sheath, long narrow spikelets
with only one flower, and a glabrous ovary and style. While working on this species at a later day, Gamble
commented, "I am rather in doubt whether Munro's specific name should not und pee. one Es
doubt was clearly noted by Blatter and McCann (1929) and y
(Munro) Blatt. & McCann. Without considering the ee species name as "itchier. several workers
erroneously spelled the epithet as ritcheyi in their publications. Nayar and Ansari (1982) also followed the
species name spelling it ritcheyi.
While preparing an account of the enumeration of Indian monocotyledons, Majumdar (1989) came to
the conclusion that the Indian species of Oxytenanthera do not fit the generic description of Oxytenanthera.
He erected a new genus, Pseudotenanthera, to include species having sub-scandent to scandent branches in
tufts, no resting central bud, a thin solid style, a pericarp thin and separable from seed, and made a new
combination Pseudotenanthera ritcheyi (Munro) R. Majumdar.
Subsequently, Naithani (1990) treated ritcheyi in the genus Pseudoxytenantl f Soderstrom and Ellis
T

(1988) to accommodate Oxytenanthera monadelpha (Thwaites) Alston which has a vine like culm, numerous
basal branches, capitate cluster of spikelets, and six stamens. Naithani (1990) maintained that Majumdar's
new genus, Pseudotenanthera, coincidentally possesses similar characters of Pseudoxytenanthera Soderstr. &
Ellis. Therefore, Naithani considered the genus a superfluous name and transferred all the species known
of Oxytenanthera from India to the genus Pseudoxytenanthera Soderstr. & Ellis.
During revisionary studies on Indian Bamboos the authors conducted a detailed comparative account
on generic characters of Oxytenanthera, Pseudoxytenanthera and noted that the Pseudoxytenanthera ritchiei
(Munro) Naithani, possesses a number of distinct characters such as, completely solid culms, prophyllum
buds without keels, inflorescence with strongly capitate heads, with leaf sheaths, palea without keels, and
a EEN ovary. The other species Hodie under the genus Oxytenanthera possesses hollow culms,
keeled p y of buds, Is without leaf sheaths, palea two keeled, and three stigmas. The
L
distinsvishimg characters of the species also were compared with other genera of the sub tribe Bambusinae
such as Dendrocalamus, Bambusa and Gigantochloa It has been noted that the diagnostic characters like
solid culms clothed with silky white tomentum; prophyllum buds and palea without keel; monostigmatic
ovary, and united filaments, together make this species distinct and therefore, belongs under a new genus
Munrochloa.
Inter generic affinities
The genus Munrochloa shows some affinities with Dendrocalamus, Oxytenanthera, Pseudoxytenanthera and
Gigantochloa. (Table 1). The habit and habitats of this taxon resembles Denrocalamus stocksii and Dendro-
calamus strictus both having thick walled culms for those clumps especially growing in dry areas. Though

of Oxyt thera and Pseudoxyt thera is divided in to ye and Munrochloa has a monostigmatic ovary
similar to Dendrocalamus and egen oa. The inter generic affinity of the Munrochloa shows that there is
an interlink between Dend d Oxytenanthera and also having distinct generic status with few key
characters like, imperfectly keeled prophyllum buds, fully solid culms, palea without any keels.

Etymology.—The generic name is to commemorate the name of Colonel William Munro (1818-1880),
who had contributed the most valuable monograph on Bamboos of the world. This genus is represented
only with a single species and endemic to Western Ghats of India.

Distribution and ecology.—This species is endemic to Western Ghats. It is distributed in northern Kerala
and Karnataka. It was also reported from Maharashtra. It is found growing from an altitude of 200-1100
m. It is a component of moist deciduous forests and also found as pure patches. Sporadic flowering is
common during summer months. Gregarious flowering was observed in the year 2001 at Nilambur forests,
Malappuram district, Kerala.
Conservation status.—This potential bamboo of south India is extracted for various uses. The recent
study by the authors revealed that the species is Conservation Dependent as per the IUCN standards and
needs appropriate tion and management strategies for a sustainable utilization of this species.
es e solid culms of this bamboo are used for making furniture, lathi, etc. It is also used as a
support for betal plants, for making baskets, umbrella handles and walking sticks.

The genera Cyperus L. and Fimbristylis Vahl consist of ca. 300 and 250
in tropical and warm regions of the world (Mabberley 1997). Karthikeyan et al (1989) in his enumeration
of Monocotyledons, listed 86 taxa (71 species) of Cyperus and 102 taxa (90 species) of Fimbristylis from
India.
During the course of botanical explorations of the tropical evergreen forests in the Western Ghats, two
interesting specimens belonging to Cyperaceae were collected viz., Cyperus (Section Mariscus) and Fimbri-
stylis (Section Fimbristylis, Series Dichotomae). Based on a perusal of the literature, comparison with the
herbarium collections at Herbarium of Cyperaceae, Majalgaon College, Majalgaon (HCMCM), BSI & CAL,
and our own field observations, the specimens were found to be very distinct and both are described here
as new species viz., Cyperus karthikeyanii and Fimbristylis naikii.

With its smoothly t surface pattern having more than 15 fine close vertical striations
or rows of thin walled cells and conspicuous tuberculations, F. naikii is very unlike to F. dichotoma or F.
merrillii J. Kern, but somewhat approaches to F. alboviridis C.B. Clarke. The latter is distinguished by the
smaller nuts (0.8—1 x 0.5-0.7 mm) and white-brown variegated nerveless glumes (ca. 2 mm long). The new
species is undoubtedly more close to F. tomentosa and can be thus distinguished from the latter and other
allies as under.

Molecular phylogeneti l f the angi d, m ifically, of Rosidae Tahkht. (summarized in

our perception of the relationships of Rosaceae, and have resulted in slight changes to its circumscription.
Traditional Rosales Bercht. & J. Presl (e.g., Cronquist 1981) included families that are now dispersed in
many orders and subclasses (Angiosperm Phylogeny Group 2003). Rosales now has a circumscription that
includes members of the former Rhamnales Linnk and Urticales Juss. ex Bercht. & J. Presl (Angiosperm
Phylogeny Group 2003). Similarly, phylogenetic analyses have led to a new classification of the Rosaceae

as a result of this analysis. One may
pa for instance, the traditional classification used by Kalkman (2004) to that of Potter et al. (2007):
the classic subfamilies Spiraeoideae Arn., Rosoideae Arn., Prunoideae Horan., and Maloideae Weber, rec-
ognized in the former, were reduced to three in the latter, Rosoideae, Dryadoideae Sweet, and Spiraeoideae.
Ihe last subfamily now incorporates genera formerly included in three subfamilies, including Prunoideae
and Maloideae. In the phylogenetic analysis of Potter et al. (2007), Lyonothamnus A. Gray appeared at the
base of Spiraeoideae, sister to all other members of the clade. In their classification, Lyonothamnus was not
assigned to a tribe. Historically, Lyonotl has been considered part of tribe Quillajeae Endl., along with
Quillaja Molina. Quillaja is now treated as the only genus in o ae D. Don of the Fabales Bromhead
(Angiosperm Phylogeny Group 2003). The subfamilial and tribal classification of Potter et al. (2007) is be-
ing used as the basis for EE Seege in the Flora of North America project (volume 9, Rosales in part).
Currently, no tribal f (Pankhurst 2007; Reveal 2006). Therefore, I am proposing
the creation of a tribe, irons made to accomodate Lyonothamnus.

The taxonomy of Lotus s.l. (Fabaceae: Loteae) has been controversial, particularly with respect to the issue
of including or excluding the North American species from the genus; Cullen (1959) and Sokoloff (1999,
2000) together provide a summary of the taxonomic history involved. Following Greene (1890), it became
usual (though not unanimous) to treat North American species within Lotus s.l., as was done, among others,
by Ottley (1923, 1944, cl (1981, 1993), Barneby (1989), Arambarri (2000), and Stenglein et al. 2003).
Traditionally, three subgenera have been recognized in North America: Hosackia, Syrmatium, and Acmispon,
the latter subdivided into sections Microlotus and Simpeteria. In the last 10 years, however, morphological
studies have shown that North American taxa were distinct from Eurasian Lotus s.s. Therefore, Sokoloff
(1999, 2000a, b; Sokoloff & Lock 2005) proposed the recognition of four genera of North American Loteae:
Hosackia, Acmispon, Syrmatium, and Ottleya (section Simpeteria segregated), corresponding with the four
traditionally used subgeneric groups mentioned above. This taxonomy was accepted by Arambarri et al.
(2005) in their numerical taxonomic study of the American species. The molecular phylogenetic analyses
of Allan and Porter (2000) and Allan et al. (2003), based on the nrDNA internal transcribed spacer (ITS),
confirmed that the North American taxa were distinct from Lotus s.s. and resulted in the recognition of two
clades among American species: pas EE clade and the clade comprising the subgenera icto id d.

Syrmatium, Sé section S pet ] Ifrerealled the A cmispo
etic on both morphological (e.g., aporte pollen, leafy stipules) and molecular bind except for he
unexplained position of L. aboriginus in Allan and Porter (2000). Nomenclatural transfer of some varieties
recognized in Hosackia species has yet to be done, however.
The taxonomic disposition of species within the Acmispon clade (Allan & Porter 2000; Allan et al.
2003) (with 4-aperturate pollen and gland-like stipules, among others) appears less clear-cut. While there
was some resolution within the clade in the ITS-based phylogenetic study of Alan and Porter (2000), Allan
et al. (2003) showed a well-supported but unresolved Acmispon clade. In the Allan and Porter analysis, sub-
genus Syrmatium appears monophyletic, with L. salsuginosus (Acmispon maritimus, sect. Acmispon, Sokoloff
2000) — L. aboriginus (Hosackia) as sister to the subclade. A second subclade includes members of sections
Simpeteria (Ottleya, Sokoloff 1999) and Microlotus (L. wrangelianus; Acmispon sect. Anisolotus, Sokoloff 2000).
It is worth noting that Ottley (1944) included her new section Simpeteria within Lotus subgenus Acmispon.

Thus Acmispon, as defined by Sokoloff (2000) and as traditionally understood, appears polyphyletic in the
ITS phylogeny, each section belonging to a separate clade. Only two Va dr ein dde were included in
the study, which prevents further conclusion. i contrary to what y suggest, it does
not seem possible to clearly delimit tl ps within the clade. Therefore, I am suggesting
that two genera should be recognized among d mcum) Loti at the present time, corresponding to the two
clades recognized in molecular analyses: Hosackia and Acmispon (the oldest generic name available for the
Acmispon clade). Given the ambiguity concerning the monophyly of lineages within Acmispon, I prefer not
to recognize subgeneric taxa at the present time, even though the Syrmatium group appears monophyletic.
The delimitation of such taxa will have to be evaluated using more complete molecular and morphological
data sets.
The purpose of this paper is to provide the nomenclatural combinations that are needed in Hosackia
and Acmispon, particularly in view of the upcoming treatments of these genera for the second edition of The
epson Manual and for the Flora of North America project. I am mainly following the taxonomy of Isely
(1981, 1993) for the North American species. A list of already accepted names in Hosackia and Acmispon for
North America north of Mexico is provided.

Micranthes nelsoniana
Recently, Brouillet and Gornall (2007) presented new combinations in Micranthes for the North American
flora. In the treatment of the genus for the Flora of North America, Elvander and Brouillet (ined.) are merg-
ing two iras did taxa e Micranthes cn (D. Don) Small in had traditionally been considered
distinct: let ifi I ildi Sul E ifi 1 varietal names exist for both entities

the varietal ievel, however, porsildiana has priority over pacifica ( y below). Dicam the varietal
level is being used for the Flora of North America EECH M publishing new names, however, Brouillet
and Gornall (loc. cit.) made a combination for var. pacifica but not for var. porsildiana. A new combination
in Micranthes for the latter is therefore required and is presented here. Since Gornall and Ohba (ined.) had
prepared combinations for all varieties in Micranthes nelsoniana, I am attributing the new combination to
these authors.

Nemacladus is an isolated genus in Campanulaceae p a B H.G. Gustafsson, Lammers 2007a,
2007b, or Nemacladaceae Nuttall, Takhtajan 1997, which include ladus McVaugh and Parishella
A. Gray) basal to the Campanuloideae and Lobelioideae (Cosner et al. 1994) or sister to a clade comprising
Cyphiaceae, Cyphocarpaceae, and Lobeliaceae (Gustafsson & Bremer 1995). Distributed in southwestern
U.S. and northern Mexico, extending south to Sonora and Baja California and north into southeastern
Oregon and western Wyoming, it is most diverse in California. Filaments connate for part of their length
distinguish it from Campanuloideae, free anthers distinguish it from Lobelioideae, and absence of a fluid
filled cavity in the stigma separates it from Cyphioideae.
A detailed study of Nemacladus has been in progress since the author prepared a treatment of it for
the Jepson Manual (Morin & Milburn 1993). Extensive field work, study of herbarium specimens, and, in
collaboration with TJ. Ayers at Northern Arizona University, analysis of DNA and study of floral and seed
morphology using SEM, have been done for a monograph that is in preparation. In order to reflect the results
of this work in the revision of the Jepson Manualin preparation, it is necessary to make some nomenclatural
changes in advance of the full monograph.
The monospecific Parishella A. Gray, found in the Mojave Desert and disjunct in mountains in Santa
Barbara County, California, has long been thought to be the genus most closely related to Nemacladus and
is here transferred into Nemacladus. In ITS (Haberle 1998), and atpB (Ayers in prep.) analysis Parishella
californica is nested within Nemacladus, with closest alliance to N. rigidus Curran. Ás in other Nemacladus,
large, clear cells are attached to the filaments; the non-resupinate, nearly actinomorphic flowers with white,
cup-shaped corolla are similar to those of N. pinnatifidus Greene.

McVaugh (1939) recognized three varieties in N. glanduliferus based on their habit and the aspect of the
pedicels, considering the flowers to be similar in all three. The flowers differ significantly, however, and
these taxa are here recognized as species. Nemacladus glanduliferus and N. orientalis are sister taxa in the
atpB and ITS analysis (Ayers, in prep.).

Etymology.—The epithet “aliformis” (from ala, wing, and -formis, with the form of) refers to the winged
appearance of the flowers, which resemble small flying insects.
Robbins (1958) helped clarify the circumscription of Nemacladus species that have resupinate flowers
with corollas that are mostly white or white with a lilac or pink tinge. One of these is Nemacladus secundiflo-
rus G.T. Robbins, known from the South Coast Ranges and Greenhorn Mountains in California. He noted
an unusual population (Raven 9138 and Bacigalupi 5649) from San Benito County but concluded it was not
different enough to warrant recognition. Study of fresh Ra ana additional populations indicates that
the flowers of these plants consistently differ from typical i in being much smaller and in having
a narrower corolla tube.
Nemacladus secundiflorus var. secundiflorus has flowers with a white corolla, sometimes with pinkish
veins, tube 2.5-3.5 mm long, broadly cylindrical, upper 2 lobes widely spreading, 2-2.5 mm long, glabrous
to hairy, lower lobes reflexed, 2.5-3 mm long; filaments + 2-2.5 mm long, anthers 0.5-0.7 mm long, with
many long, ca. 0.7 mm hairs. South Coast Ranges in Monterey and San Luis Obispo counties, and the
Greenhorn Mountains in Tulare and Kern counties.

Em 08y. moo i is named in honor of Guy Thomas Robbins, 1916-1960, in recognition of
his ] dies of Nemacladus. He received a B.S. from the University of California, Berkeley
and an M.S. at University of Colorado, Boulder, after which he was on the faculty at University of Arizona and
at Oklahoma State College, ine He then entered the Ph.D program at University of California, Berkeley and
in 1952 took a full-time position as a Research Botanist in the Jepson Herbarium. In addition to his work on
Nemacladus, he published a revision of North American Androsace (Robbins 1944). Additional information
about his life can be found in the memoirs of Lavinia Pearl Butler Robbins (1882-1985), his mother, who
donated her memoirs in 1972 to the Bancroft Library at University of California, Berkeley, in his memory.

calyx lobes splayed outward.
Nemacladus calcaratus is known only from the Chimney Creek area, Tulare County, California at the
southern end of the Pacific Crest.
Etymology.—Calcaratus is in reference to the nectar spur. Ertter et al. (6331) noted the red stripes on
the corolla, and Boyd and Bramlet (1931) pointed out the small spur. It is the first species of Nemacladus
known to have a definite nectar spur, although the corolla of Nemacladus ramosissimus Nutt. 1s gibbous. The
flat ovary apex and relatively large corolla with all petals n ad: on the upper part are also distinctive.

INTRODUCTION
Prunus is one of the larger genera of the Rosaceae with about 200 species, which are most abundant in the
North Temperate zone but also range into the tropics and Southern Hemisphere (Rehder 1940; Robertson
1974). It is important commercially as the source of cherries, almonds, peaches, nectarines, apricots, and
plums; numerous species are grown ornamentally for their beautiful early-spring flowers. The classifica-
tion of Prunus has been debated from Linnaeus to the present day, with some botanists arguing for a broad
concept of the genus that includes all of the fruits mentioned above (e.g., McVaugh 1951; Robertson 1974)
and others dividing Prunus into a variety of segregate genera including Amygdalus, Armeniaca, Cerasus,
Laurocerasus, Padus, and Persica (e.g., Iwatsuki et al. 2001; Flora of China Editorial Committee 2003). The
most widely used classification has been that of Rehder (1940) who recognized Prunus in its broad sense
with five subgenera.
At the species level there has been considerable taxonomic uncertainty among the North American
plums (Prunus sect. Prunocerasus) In 1892 Bailey called Prunocerasus the "hardest puzzle in American
pomology,” a memorable phrase quoted by Shaw and Small (2004) more than a century later in reporting
the use of multiple cpDNA sequences to bear on this enduring puzzle. Shaw and Small (2004) provided an

extensive review and analysis of the taxonomic history of P and they noted that the unresolved
classification of North American plums is the result of inters] imilarities, intraspecific variation, and
probably interspecific hybridization.
The earliest studies using DNA sequences to examine relationships in Prunus focused on a limited
number of cultivated species (Badenes & Parfitt 1995; Uematsu et al. 1991). In 2001 two research groups
sought to clarify phylogenetic relationships among the subgenera and numerous sections of Prunus by ex-
amining species on a worldwide scale (Bortiri et al. 2001; Lee & Wen 2001). Unfortunately relationships
among the species of section Prunocerasus remained unresolved. Both groups used ITS sequences and found
slight variation among the native plums included in their studies. Analyses by Bortiri et al. (2001) using
chloroplast trnL-trnF sequences ; also dia nd slight variation among six North American species.
Rohrer et al. (2004) used alysis in an attempt to find molecular markers more variable
among species of Prunocerasus than ITS or trn seque However, all pairs of species in the study shared
fewer than half of their alleles, indicating greater geneti g mong the North American plums than
expected given their similar ITS and trn sequences. Accessions of two or three individuals of the same spe-
cies often did not cluster together, suggesting that microsatellites La ad too Ms to be informative in
resolving species relationships in Prunocerasus. Seeking to test the] monophyly for Prunocerasus
and to resolve relationships among the species, Shaw and Small (2004, 2005) turned to seven noncoding
regions in the chloroplast genome shown to be highly variable across a wide array of taxa (Shaw et al. 2005).
Given their taxonomically broad sampling of species both within the section and across all of Prunus, Shaw
and Small (2004, 2005) provided unequivocal support for the monophyly of sect. Prunocerasus. Within the
section the analyzed sequences varied little among the species. They demonstrated strong support for P.
subcordata as sister to the rest of Prunocerasus. An unexpected result was the inclusion of the hairy-fruited
P. texana within Prunocerasus positioned between P. subcordata and the other species, which formed three
primary clades with little resolution within each clade. Many of the species have exemplars on more than
one clade, and the chloroplast haplotypes show greater correlation with geography than species limits.
Bortiri et al. (2002) demonstrated that the nuclear gene s6pdh was more variable among Prunus species
than either ITS or trn and showed greater promise for resolving relationships in the genus. However, only
three species of Prunocerasus were included in their analysis. In addition, Oh and Potter (2003) reported
sequences from the second intron of the nuclear gene LEAFY were more phylogenetically informative than
either ITS or cpDNA in the rosaceous genera Mine ane Stephanandra. In this study we explore the use of
these low-copy nuclear genes for resolving relati among the species of Prunocerasus. Specifically we
expand the use of s6pdh to all commonly recognized nE in KR section and include seq from the
second intron of LEAFY.
MATERIALS AND METHODS
Plant Material —We were able to obtain at least one accession from each of the 15 (or so) species of North
American plums. The exact number of pes is subject to the differences in opinion concerning species
circumscriptions that ani ebate. Apricot (P. armeniaca), cherry plum (P. cerasifera), and two
varieties of sand cherry (P. pumila var. pumila and P. pumila var. susquehanae) were used for outgroup com-
parison. In all, we analyzed 37 accessions of North American plums plus the four outgroup taxa (Table 1).
Some specimens were collected from wild plant populations; others were collected from cultivated plants of
the University of California, Davis campus, the USDA National Clonal Germplasm Repository in Davis, and
the USDA Southeastern Fruit and Nut Research Station in Byron, GA. All sources of DNA are documented
by ] j ted in the University of Wisconsin-Eau Claire herbarium (UWEC). We verified
TTT against published descriptions and authentic herbarium material.
DNA Extraction, Amplification, and Sequencing.—Total DNA was isolated by grinding approximately
100 mg (wet weight) of fresh or frozen leaves in liquid nitrogen and using the DNeasy Plant Mini Kit (Qia-
gen) according to the standard protocol. We prepared PCR reactions in 50-pl volumes containing ~10 ng

of genomic DNA, 1.25 units of ExIaq DNA polymerase (Takara), 1x PCR buffer, 200 pM dNTPs, 0.2 uM of
each primer, and sterile water. Intron 2 of the nuclear gene LEAFY was amplified using primers modified
from Oh and Potter (2003): LFY5: 5'-CAGAACATTGCCAAGGAGC-3', LFY4: 5'-GGCTTGTTGATGTAGCT-
TGC-3'; and nuclear gene s6pdh from Exon 2 to Exon 6 was amplified using primers modified from Bortiri
et al. (2002) plus a new primer (0): sópdh-k: 5'-CAAGAGTGAAGCAGACGTTGG-3', s6pdh-h: 5-AGACCA-
ATGCTACGAACTAGGCCG-3', s6pdh- o: 5'-AGAATAAGGTGTTGGACATAGACG-3', s6pdh- p: 3'-AGAGTG-
GTCCTGGATTTCTTATCTA-3’. Thirty-five cycles of three-step PCR, preceded by an initial melti p of 4
min at 94°C and concluded by a final extension of 7 min at 72°C, were carried out as follows: den
at 94°C for 30 sec, primer annealing at 52°C (LEAFY) or 54°C (s6pdh) for 1 min, and extension at 72°C
for 2 min.
Following electrophoresis we excised PCR products from 1% agarose gels and purified them using a
QlAquick Gel Extraction Kit (Qiagen). We sent the fragments for direct sequencing using the PCR primers
either to Davis Sequencing (Davis, CA) or the DNA Sequence Laboratory of the University of Wisconsin
Biotechnology Center (Madison, WT). PCR products with unreadable sequences or a significant number of
ambiguous base calls were cloned using the TOPO TA Cloning Kit for Sequencing (Invitrogen) following
the manufacturer's instructions. Sequencing of all clones using T3 and T7 primers was done by the DNA

nelysium Pty Ltd), and the Ses ess were aligned by eye in GeneDoc 2.6.002 (Nicholas & Nicholas 1997).
The close relationship among P jes made manual alignment of the sequences straightforward. For
data analysis, parsimony informative indels were coded as additional binary characters. Seven indels were
included for LEAFY and eight for s6pdh. LEAFY sequences were trimmed to just Intron 2; s6pdh sequences
were truncated to begin 18 bp downstream from the end of primer k, located in Exon 2, and end 14 bp
upstream from the start of primer p in Exon 6. Sequences were submitted to GenBank (accession numbers
listed in Table 1).
Phylogenetic Analyses.—Both data sets were analyzed using maximum parsimony (MP) with PAUP*
4.0b10 (Swofford 2002) and Bayesian inference (BI) with MrBayes 3.1.2 (Huelsenbeck & Ronquist 2001;
Ronquist & Huelsebeck 2003). Two heuristic MP searches with TBR branch swapping and the Multrees
option were performed: the first with MaxTrees set to one million; in the second, the “nchuck” and “chuck-
score" options were employed so that 10,000 trees were saved and swapped for each of 30 random addition
replicates. The results of each search were summarized as strict consensus cladograms. Relative support
for each branch was assessed by heuristic searches of 1000 bootstrap replications with 10 random addition
replicates each and TBR branch swapping. For each random addition replicate 100 trees were saved. For
BI analyses each data set was partitioned into nucleotide characters and indel characters. ModelTest 3.7
(Posada & Crandall 1998) was used to select the substitution model that best fit the nucleotide data using
the Akaike information criterion: TVMef for LEAFY and HKY+I+G for s6pdh. Each of two BI runs for each
gene consisted of three heated and one cold chain with samples drawn every 100 generations. We ran the
LEAFY data for 1,000,000 generations discarding the first 500,000 generations, whereas for s6pdh we ran
1,500,000 generations discarding the first 750,000 generations. The runs for each data set were combined
and a majority rule consensus tree constructed with a 6796 threshold.
Determination of chloroplast haplotypes.—In order to compare our phylogenetic results from nuclear
LEAFY and s6pdh with those of Shaw and Small (2004, 2005), we sequenced the trnL-trnF intergenic spacer
from the chloroplast genome for our accessions. We amplified the spacer using the e-f primer pair of Taberlet
et al. (1991) and used primer e, and sometimes primer f, for sequencing (GenBank accessions EU606152-
EU606192). We aligned the 18 Prunocerasus exemplars used in Shaw and Small
L
406 | ti tanical Insti lexas 2(
(2004). The maximum parsimony tree from the combined dataset was used to place each of our native plum
accessions into one of the primary chloroplast haplotypes (A, B, C, S, or T) of Shaw and Small (2005).
RESULTS
For clarity in the results and discussion sections we refer to specific sequences by their names on the phy-
lograms, omitting the genus name and differentiating among clones from the same collection by decimels
following the last three digits of the collection number
LEAFY Alignment and Data Analysis.—PCR with primers LFY5 and LFY4 yielded fragments approxi-
mately 750 or 1000 nucleotides in length, the difference being a 250-bp insertion. Only 1000-bp fragments
were PCR amplified for Prunus hortulana and P. murrayana. All three individuals of P. rivularis and two of
the four collections of P. munsoniana (513, 676) had both 750 and 1000-bp fragments (Fig 1). The other
collections of P. munsoniana and the remainder of the species yielded only 750-bp fragments. Some of the
cloned P. rivularis sequences appeared to be recombinations of the 750 and 1000-bp sequences, similar to
those of P. angustifolia and P. hortulana/P. murrayana respectively (Fig 2). Putative recombinant sequences
were omitted from the phylogenetic analyses. Trimmed to LEAFY Intron 2, the ingroup sequences varied
in length from 658 bp in P. texana to 925 bp in one clone of P. rivularis (528.22). The final alignment used
in the LEAFY data analysis included 930 nucleotide characters, of which 856 were invariant, 35 varied but
were parsimony-uninformative, and 39 (4.296) were parsimony informative for the ingroup taxa.
The strict consensus MP cladograms from the two parsimony analyses are identical (not shown), each
of length 194 with consistency index (CI) of 0.634 and retention index (RI) of 0.796. Their topologies are
similar to the Bayesian analysis phylogram (Fig. 3), but several nodes (indicated by the solid circles) are
collapsed and there are minor rearrangements within Clades 3 and 4 (topology indicated by dotted lines).
Species of Prunus sect. Prunocerasus form a monophyletic group split into three lineages: P. subcordata plus
Clades 1 and 2. Clade 3 is composed of P. angustifolia and angustifolia-like sequences from P. munsoniana
and P. rivularis. The latter two species (names in bold on Fig. 3) also have cloned sequences from the same
individuals on Clade 2. Relationships among P. americana, P. mexicana, and P. nigra are unresolved; they
diverge from a basal polytomy on Clade 2. Sequences of Clade 4, including those of P. hortulana, P. mur-
rayana (except 5255), P. munsoniana, and P. rivularis, have a 250-bp insertion not found among the other
sequences.
s6pdh Alignment and Data Analysis.—The final ali t for the s6pdh analysis includes 1272 nucleotide
characters, of which 1197 were invariant, 46 varied but parsi inf tive, and 29 (2.3%) were
parsimony informative for the Prunus sect. Prunocerasus species. The Soest gthe ingroup
were those of P. hortulana (628), P. maritima, and P. subcordata at 1204 Alice des including 7 or 8 IC
repeats in Intron 3, whereas one P. americana clone (505.2) had the longest sequence at 1256 nucleotides
with 31 TC repeats.
Just as in the LEAFY analyses, the strict consensus MP cladograms from both parsimony analyses of
s6pdh are identical (not shown) and have lengths of 153, consistency indices (CI) of 0.699, and retention
indices (RI) of 0.854. The MP cladograms are nearly identical to the BI phylogram (Fig. 4). On the MP cla-
dograms, Clades 5 and 6 are sister groups such that Prunus sect. Prunocerasus forms a monophyletic group,
albeit with bootstrap support less than 5096, the branch indicated by the black circle is collapsed, and
americana.684.1 is sister to americana.495.3/americana.505.23 on Clade 5 (indicated by dotted lines). Clade
5 includes P. subcordata plus subcordata-like sequences from five individuals of P. americana and one of P.
munsoniana. These accessions (names in bold on Fig. 4) also have sequences on Clade 6, which includes all
the other native plum taxa. There is poor resolution among these taxa. Prunus angustifolia, P. texana, and
angustifolia-like seq from P. munsoniana and P. rivularis compose Clade 7. Clade 8 consists solely of P.
americana and P. mexicana, plus a similar sequence from one individual of P. umbellata (520.4), which also
has a sequence among the taxa of the Clade 6 basal polytomy (umbellata.520.3).

DISCUSSION
The nuclear genes LEAFY and s6pdh provide weak resolution of relationships among species of Prunus sect.
Prunocerasus. The majority of taxa diverge from polytomies on the MP consensus and BI trees. The topology
of these trees is different from the cpDNA cladogram of Shaw and Small (2005) where P. subcordata and then
P. texana are sister groups to the remaining species, which segregate into three primary clades: American

(A), Beach (B), and Chickasaw (C). Clade 1 on the LEAFY tree and s6pdh Clades 5 and 7 consist largely of
accessions with cpDNA haplotype C, otherwise taxa on the nuclear gene trees do not resolve into the A,
B, and C clades of Shaw and Small (2005). fica qas all chloroplast and nuclear phylogenies is

American ds are ee to os endis (Medel 1911; Shaw & Small 2004).
Although Prunus texana, known as peachbush or Texas wild peach, has historically been placed in
sect. Amygdalus due to its hairy-skinned fruit, Shaw and Small d dée that it has a plum chloroplast
genome. Evidence from the nuclear genes LEAFY and s6pdh tin sect. Prunocerasus. On
the cpDNA cladogram P. texana was sister to the other pums of eastern North America, a position we could
not confirm. It is sister to P. geniculata, the rare endemic of the Lake Wales Ridge in central Florida, on our
LEAFY phylogram. However, this relationship is based on one character change and has weak bootstrap
support. On the s6pdh phylogram P. texana is part of Clade 7 with P. angustifolia and the angustifolia-like
sequences of P. munsoniana and P. rivularis.
Prunus alleghaniensis, P. gracilis, P. maritima, and P. umbellata form a paraphyletic group on LEAFY
Clade 1, basal to Clade 3. These four species clustered on the UPGMA dendrogram based on similarity
of microsatellite markers in the study of Rohrer et al. (2004). These species closely resemble each other
morphologically and were allied by early students of American plums such as Wight (1915). On the sópdh
EE EE are part - the a Clade 6 basal bis
Prunus 1 be difficult to sep hologically, especially when working
with herbarium specimens. pue their LEAFY and s6pdh sequences were mia and without resolution
into monophyletic P. americana and P. mexicana groups. On the LEAFY phylogram the P. americana and
P. mexicana sequences diverge from a basal polytomy along with P. nigra, munsoniana.592.1, and Clade 4.
LEAFY sequences americana.508 (WD, americana.684 (PA), mexicana.518 (TX), and mexicana.545 (cult.)
differ trivially by the length of a poly-A run and some nucleotide characters heterozygous for one or two
sequences but with only one of the two bases on the other sequences. Otherwise they are identical.
Although our data do not separate Prunus americana from P. mexicana sequences on either LEAFY
Clade 2 or s6pdh Clade 8, Boonprakob et al. (2001) calculated a UPGMA dendrogram, based on similarities
of RAPD markers, on which all 13 of their accessions of P. americana clustered together and distinct from
a cluster of all 11 accessions of P. mexicana. Clearly more collections with a wide geographic distribution
and more genes will need to be examined and correlated with the morphological characteristics of those
accessions before the taxonomic structure of the P. americana-mexicana complex is understood.
In an earlier microsatellite study, Rohrer et al. (2004) included two collections from east Texas near
Marshall Ge e P (americana x mexicana?) 10517 and 10518 in that publication) that are morpho-
logically int typical Prunus americana and P. mexicana. The lack of differentiation between
P. americana and P. mexicana LEAFY and s6pdh ee leaves their determination ambiguous. However,
because neither 517 nor 518 have a subcordata-like s6p e and | t modern fl exclude
P. americana from Texas, we have provisionally deeem ed these accessions to be P. mexicana.
Two distinct sequences were isolated from five of the six accessions of Prunus americana by cloning
their s6pdh PCR products. One sequence from each pair is on Clade 8 along with P. mexicana and the single
sequence of P. americana oe the omen is on Clade 5 with P. subcordata. Given that Së P. americana se-
quences form a ph; group sister to P. subcordata and that P. subcordat y in California and
Oregon, far west of P. ge in eastern North America, it seems alle that che five P. americana
collections with two s6pdh sequences are recent hybrids independently involving P. subcordata. If sópdh is
a single copy gene in all diploid Prunus species as concluded by Bortiri et al. (2002) and if P. americana is
diploid as it is reported to be (2n = 16, Love & Love 1982), then a high degree of heterozygosity is being
maintained at a single locus. However, we cannot rule out the possibility that there are two heterologous
Rohrer et al., Phyl g ti lysis of North A j p t. Prunocerasus 411
ancestral s6pdh loci across Prunus with only one or the other copy observed in most North American plums,
or alternatively gene duplication in P. americana. Bortiri et al. (2002) found divergent s6pdh sequences in
Prunus caroliniana and P. emarginata. They | thesized that divergent paralogs in P. caroliniana, a tetraploid
species, may have arisen through EHE np lesion associated with polyploidization. In P. caroliniana the
inferred polypeptides of the diver ger ent clones es at P» of 251 amino acids (Bortiri et al. 2002), whereas
for each of our five accessions of Prunus americana with divergen t s6 , the inferred polypeptides
of the two clones differ by only 1—4 out of 223 amino ads To Boer pan the existence of divergent
sequences in P. americana, it would be useful to have chromosome counts from each of those accessions to
verify that they are indeed diploid. Also because Southern blotting with a Malus domestica cDNA s6pdh probe
by Bortiri et al. (2002) detected more than one region of sequence similarity in several genera of Rosaceae,
the possibility of paralogous genes might be further investigated.
Alleles closely related to those of Prunus americana, and possibly P. mexicana, were found in other plum
species suggesting introgression. P iana 592 has both s6pdha EAFY sequences monophyletic
with sequences from P. americana 607. On the sópdh tree munsoniana 592.23 is i with the five subcordata-
like P. americana clones and has the same amino acid sequence as americana.495.3 and americana.505.23.
On the LEAFY tree munsoniana.592.1 is sister to americana.607. Also P. umbellata 520 has an americana!
mexicana-type s6pdh sequence (umbellata.520.4) in addition to a sequence similar to that of the P. umbellata
620 collection.
Sequences from both LEAFY and s6pdh suggest that Prunus rivularis may be an allopolyploid with P.
angustifolia as one parent. The LEAFY sequences further suggest that the other parent is most likely P. hor-
tulana or P. murrayana and that recombination between parental sequences has taken place. Three or four
distinct sequences were cloned from each of the P. rivularis accessions. LEAFY is believed to be a single-copy
nuclear gene (Frohlich & Parker 2000; Oh & Potter 2003) and would be expected to have one or two alleles
in a diploid species. At least one sequence from each P. rivularis accession is monophyletic with sequences
of P. angustifolia (Clade 3 on the LEAFY phylogram and Clade 7 on the sópdh phylogram). The other se-
quence is on Clade 4 of LEAFY along with sequences of P. hortulana and P. murrayana. In addition, some
LEAFY recombinant sequences were cloned where part of the sequence matches P. angustifolia and the rest
matches P. hortulana/murrayana (graphically illustrated on Fig. 2). Although it is possible for recombinant
sequences to arise as PCR artifacts (Cronn et al. 2002; Posada et al. 2002), in our study they were isolated
only from P. rivularis and they were found among the LEAFY sequences of all three P. rivularis accessions.
This would seem to support the hypothesis that the recombinant sequences arose through meiotic recom-
bination following hybridization between P. angustifolia and either P. hortulana or P. murrayana. Given the
few phylogenetically-informative characters in the s6pdh data, if there were recombinant s6pdh sequences,
we were unable to identify them.
Plants in our study determined as Prunus munsoniana appear to be a mixture of hybrids having P. an-
gustifolia as one of the parents. All four P. munsoniana collections have a LEAFY sequence on Clade 3 with P.
angustifolia and P. rivularis, and three collections have s6pdh sequences on Clade 7, again with P. angustifolia
and P. rivularis (we are lacking a s6pdh sequence for P. munsoniana 676). Two P. munsoniana collections (513
and 676) have a second LEAFY sequence with the 250-bp insertion found also among sequences B P. hortu-
lana, P. murrayana, and P. rivularis on Clade 4. On the BI cladogram, munsoniana.513.2 676.3
form a trichotomy with rivularis.527.24, but on the MP cladogram they are sister to hortulana.628. Thus,
these two P. munsoniana collections have LEAFY sequences closely related to those of P. rivularis, which lends
support to the suggestion by Diggs et al. (1999) that P. munsoniana is simply a larger version of P. rivularis.
However, the other two specimens of P. munsoniana (592 and 626) lack hortulana/murrayana-like LEAFY
sequences, yet are very similar morphologically to 513 and 676. For P. munsoniana 626 we were only able
to isolate angustifolia-like LEAFY sequences. Likewise we isolated only a single s6pdh sequence, which lies
on Clade 7 with P. angustifolia and P. rivularis. P. munsoniana 513 and 592 each yielded three distinct s6pdh

sequences, suggesting that at least some P. munsoniana

has a sequence on s6pdh Clade 7 (592.24) with P. angustifolia, and on Clade 5 (592.23) sister to a clone of
P. americana (607.2), just as on the LEAFY phylogram. The third sópdh sequence (592.21) is sister to rivu-
laris.527.2 and these two are sister to munsoniana.513.1.
To our knowledge we are the first to suggest a close phylogenetic relationship between Prunus mur-
rayana and P. hortulana (Clade 4 on the LEAFY phylogram). P. murrayana.525L and murrayana.526 form a
clade with hortulana.598.1 having 93% MP bootstrap support and 100% BI posterior probability. The s6pdh
sequences do not confirm or refute the close relationship between P. murrayana and P. hortulana, because
their sequences along with those of P. alleghaniensis, P. geniculata, P. gracilis, and several other species all are
unresolved on the Clade 6 basal polytomy. Until a decade ago, P. murrayana was a poorly known species
endemic to Texas west of the Pecos River and represented in herbaria by only a handful of specimens. When
originally described, Palmer (1929) wrote that it might be most closely related to P. rivularis. Enquist (1997)
formalized this relationship by designating P. murrayana as a synonym when he described P. rivularis var.
pubescens Enquist. He discovered numerous plums on the western don e the Edwards Plateau SH pubes-
cent first-year branchlets, pubescent pedicels, and pul ,an led that
these plants were the same taxon as P. murrayana — from her west Many di Enquist's collections
are morphologically well matched with authentic P. murrayana specimens. He explained how most of the
apparent differences between P. murrayana and P. rivularis did not hold in light of the new collections and
that the only distinguishing character was pubescence; the branchlets, pedicels, and petioles of P. rivularis
are glabrous or Pd so (Enquist 1997). Clade 4 of ER LEAFY phylogram includes not only P. hortulana
and P. from all three accessions of P. rivularis and a couple from P. munsoniana.
Our P. Wu IA eden: are from Coke and Tom Greene Counties east of the Pecos River at localities
where Enquist (1997) collected P. rivularis var. pubescens [= P. murrayana]. These collections have only Clade
4 LEAFY sequences, whereas our three collections of P. rivularis have both Clade 4 and Clade 3 sequences.
SE P. Mii i accessions have s6pdh sequences only from the Clade 6 polytomy, whereas all three
s have a cloned sequence on Clade 7 with P. angustifolia and from the basal polytomy of
Clade 6. We believe that P. murrayana is a diploid species distinct from P. rivularis, which we believe is an
allopolyploid derived from P. angustifolia and either P. murrayana or P. hortulana.

Recent investigations in the taxonomy of tribe Colurieae Rydberg of the Rosaceae have led to the conclu-
sion that Waldsteinia Tratt. is abu ou - embedded within Geum L. and Pedes be combined with it
(Smedmark 2006). Smed 2006), Smedmark et al. (2003), and Smed ] Eriksson (2002) presented
11 1 a
strong evidence that Waldsieiniái is involved in ancient from which parts of Geum have
arisen, and they argue that the most reasonable GER of the genus is to include all the perennial
herbs of Geinae involved in the reticulate evolution. Morphologically, Waldsteinia is comfortably congruent
within a broadly defined Geum, differing only in the style dehiscent at its base; and Geum (in a narrower
sense) already includes a wide diversity of style morphologies, apparently adaptations to a variety of pol-
lination and dispersal Denon due
Most North American ted three taxa of Waldsteinia for eastern North America: Taxon
A (" fragarioides," sensu stricto), a northern EE entity with trifoliolate leaves; Taxon B “parviflora”
r "doniana"), a southern smaller-petaled entity with trifoliolate leaves; and Taxon C (“lobata”), a Southern
Aun endemic with small petals and lobed, rather than trifoliolate, leaves (Table 1). A notable excep-
tion to the acceptance of Taxon A and Taxon B as distinct at some formal taxonomic level is the treatment of
Radford et al. (1968), which lumps Taxa A and B and does not mention W. lobata, reported for the Carolinas
by earlier authors. Smedmark (2006) made transfers into Geum of Waldsteinia species, but regarded Taxon
B asa synonym of Taxon A (without explanation, but perhaps because of the nomenclatural and taxonomic
confusion discussed below), leaving it without a name in Geum.
Although their acceptance as taxa has been nearly universal, the appropriate taxonomic level at which
to recognize these entities (species, subspecies, or variety) has remained controversial and variable (Table 1).

variation in petal size. Moreover, the “Waldsteinia group" of i lly conservative, with rela-
g taxa on different BN such) as the North Ámerican
tively minor morphological characters set
G. fragarioides and the Eurasian G. ternatum (Stephan) Smedmark. Indeed, the morphological relationships
of the three taxa make the closer affinity of Taxon B problematic (if leaf lobing is the more phylogenetically
revealing character, then Taxon B may be more closely related to Taxon A, but lacking molecular data it is
plausible that the floral characters are more phylogenetically revealing, and taxa B and C are more closely
related, forming a southern, small-petaled clade). For these reasons, we agree with Phipps (in prep.) that the
best current (and conservative) taxonomic treatment of the “Waldsteinia group” in eastern North America
is as three species.
Nomenclature has also been contentious, with disagreement as to the appropriate basionym (doniana'
or ‘parviflora’) to apply to Taxon B (Table 1). Fernald (1935) believed that the application of the epithet 'do-
niana' to the small-petaled southern taxa was a misapplication. He argued that the type plate "seems to me
a garden-development in which, presumably through unwonted nutrition, the sepals become exaggeratedly
large, the petals remaining fairly typical for W. fragarioides.” Teppner (1968) convincingly argued the op-
posite case, that the relative size of the sepals and petals are clearly shown and described, and this primary
diagnostic characteristic between the two taxa should be taken at face value. A review of the description
and plate (which serves as the type) confirms Teppner's opinion, making ‘doniana’ the correct basionym for
the southern taxon, should it be recognized taxonomically at the specific level. The plate in Sims (1813) (on
which Trattinick's name is based) resembles Taxon B closely and obviously, in that it shows a plant with
petals shorter than the sepals, a characteristic that is also stated in the text of both Sims (1815) and Trattin-
ick (1823) as a distinctive or diagnostic characteristic. The stated provenance of the plant illustrated (Sims
1813) is pertinent, as well: “the plant, from which our drawing and description were taken, was brought
from America, by Mr. Lyons [sic], and purchased at his sale, by Mr. Kent, of Clapton, by whom it was kindly
communicated to us.” Ewan & Ewan (1963) show that John Lyon listed this plant in a catalogue in 1812 (as
y i, | ic history of Waldes teinia 417
Dalibarda fragarioides), and also listed Mr. William Kent as having purchased plants for 14 £, 18 sh. in 1812.
Presumably the plant illustrated the following year was in this lot. Though the location from which Lyon
collected the plant cannot apparently be definitely known, the identification of John Lyon as the source of
the plant illustrated and described is of interest, since Lyon collected extensively within the southeastern
United States range of the small-petaled Taxon B. Thus, it seems very plausible that the plant described and
figured as Waldsteinia fragarioides by Sims, and later described and named by Trattinick as the distinct W.
doniana, is exactly what it appears to be.
Based on our review of generic circumscription, taxonomic distinctiveness, appropriate taxonomic
rank, and nomenclature, we hereby effect the transfer of "Taxon B" to Geum at the rank of species:

The Nyctaginaceae is a taxonomically complex family because of the heavy reliance upon mature fruit for
identification (Galloway 2003; Welsh 2003). This is particularly true in the genus Abronia, where vegetative
morphology can be highly variable within and among species while fruit morphology remains constant and
distinct among taxa. The genus Abronia consists of 20 species, distributed throughout the Southwest, high
Great Plains, Mexico, coastal California, and Pacific Northwest (Galloway 2003). Five species have been
reported for the state of Colorado: Abronia argillosa Welsh & Goodrich, A. carletonii Coult. & Fisher, A. el-
liptica A. Nelson, A. fragrans Nutt. ex Hook., and A. nana S. Wats. var. nana. Abronia bolackii Atwood, Welsh
& Heil is a newly described species endemic to San Juan County, New Mexico (Atwood et al. 2002).
Abronia argillosa is practically identical to A. elliptica vegetatively, and it is only through analysis of the
fruit that identification can be made. Both species are perennial from a branching caudex with elliptic to
ovate or suborbicular, entire leaves, and with white or purplish tinged flowers grouped in heads that are
subtended by ovate to suborbicular bracts. However, Abronia argillosa has wingless fruit while A. elliptica has
winged fruit with the wings dilated and inflated at the top (Fig. 1A,C). Abronia argillosa was described in
1980 (Welsh & Goodrich 1980) as a new species Pas Utah and Colorado restricted to Mancos Shale sub-
strates. Examination of the original description of Abronia glabrifolia (Standley 1909) and the type specimen
[Colorado: 1878, Wm. F. Flint s.n. (UC)] e that this is deai the same species. The type specimen of A,
glabrifolia has the characteristic dark brown, wingless fruit with conspicuous white lines seen in the fruit of
A. argillosa (Fig. 1C). The name Abronia glabrifolia predates that of Abronia argillosa by almost 70 years, and
should thus be the name applied to all specimens of A. argillosa. William F. Flint was in Colorado at the Los
Pinos Indian Agency in 1878 (Flint 1878), where he also collected a type specimen of Senecio flintii Rydb.
[Colorado: S.W. Colorado, Wm. F. Flint s.n. (NY)]. Los Pinos was the name for the Ute Indian Agency, located
about 25 miles north of Ouray and 11 miles south of Montrose, near the town of Eldredge (Young 1997), on
what was then the reservation for the Uncompahgre Ute tribe. This locality is close to the Montrose-Ouray
County line. Mancos Shale, the type of habitat known to support A. glabrifolia populations (Fig. 2), occurs
in the vicinity.

The presence of Abronia carletonii in Colorado in particular has been questioned or misinterpreted by
numerous taxonomists (Weber & Wittmann 2001). Assumption of its presence was based on the type col-
lection made by Mark Carleton in 1891, and attributed to eastern Colorado. Abronia carletonii has not been
collected in the state since, but is known to occur in New Mexico and Texas, where it is usually restricted to
gypsum soil, very unlike the sandy soil that is found on the eastern plains of Colorado. Examination of the
type specimen of A. carletonii [Colorado: Eastern Colorado, 1891, M.A. Carleton 459, (F)] confirms that it is
actually a narrow-leaved, trailing form of A. fragrans. The fruit is winged, but the wings are not dilated and
are thick and indurate as in typical A. fragrans (Fig. 1B). This form of A. fragrans is seen in other specimens
from the plains growing in sandy soil [Colorado. Baca Co.: sand hills on south bank of Cimarron River,
31 Aug 1949, Weber & Anderson 5157 (KANU); Kansas. Finney Co.: ca. 2.5 mi S Garden City, scattered in
sand dune area south of Arkansas River, 11 Sep 1989, Brooks & McGregor 19676 (KANU)]. In addition, the
specimen was probably not collected in Colorado at all, but in extreme southwestern Kansas, just north of
Elkhart, where the only Abronia known to be present is A. fragrans. The name A. carletonii should now be
subsumed under A. fragrans, and specimens of A. carletonii in New Mexico and Texas should be referred to
as A. nealleyi Standley, as suggested by Turner (2004).
In the Holzinger tabulation (Holzinger 1892), collection number 459 is not an Abronia at all, but is
shown to be Cnicus altissimus and was collected in Kingfisher County, Oklahoma in August. The specimen

labeled collection number 459 of Abronia carletonii likely has the wrong label information, and is probably
collection number 352 of Abronia fragrans collected in July in Morton County, Kansas, along the Cimarron
River, probably near Point of Rocks north of Elkhart. According to Holzinger (1892), Carleton collected
in Oklahoma, Kansas, and Texas, but not Colorado. Carleton began his collection trip in Oklahoma in
June, collecting in the Cimarron Valley (collection numbers 202-235). He then continued north to Kansas
where he collected until July (collection numbers 236-353), traveling across the southcentral counties of
Comanche, Barber, Harper, and Sumner before going north to Sedgwick County. He continued westward
from Wichita making collections in Reno and Stafford counties, and then in Seward, Stevens, and Morton
counties in extreme southwestern Kansas. Carleton then traveled back to Oklahoma and Texas in July and
August (collection numbers e ALA).
Some taxonomists consider Abronia elliptica to be with, or a variety of, Abronia fragrans. In
particular, Welsh (2003) includes A. elliptica within a broad: concept of A. fragrans. However, he misquotes
Galloway (1975) as saying that the fruit of A. elliptica is 2-winged with a groove between the wings, and
that of A. fragrans is 2-5-winged but not especially grooved. In fact, Galloway (1975) states that A. elliptica
is 5-winged or 2-winged with the wings folded together, with dilated wing tops on the fruits that are not
folded. Galloway (1975) further states that A. fragrans is deeply grooved or narrowly winged, with thick wings
that are not inflated at the top. The fruits on the periphery of the heads in both A. fragrans and A. elliptica
are often contorted, with 2 wings folded together, while the fruits in the middle of the head are 5-winged.
Careful analysis of the fruit as well as habit shows that A. elliptica and A. fragrans are indeed different
species, as shown by the following characters. First, the fruit of A. fragrans is wingless or winged, with hard,
rather indurate wings that are flat and lacking dilations (Fig. 1B). The fruit on the periphery of the heads is
41
422 t tani i Texas 2(1)
often wingless in A. fragrans while within the central portion, fruits are winged. In contrast, A. elliptica has
winged fruit with papery thin wings that are inflated and dilated at the top (Fig. 1A). Second, A. fragrans
is generally a prostrate and spreading or semierect plant with more robust stems 3-5 mm wide, and with
leaves that are ovate to triangular or lanceolate, especially on the upper part of the stem. Abronia elliptica,
however, is generally erect or sometimes ierect with narrower stems typically 2-3 mm wide, with ovate
to elliptic-oblong leaves. In addition, the distribution of A. elliptica in Colorado is scattered in the western
counties. In contrast, A. Jaunes is common on the eastern peus but is also found in Chaffee County near
Buena Vista. It is int ties with a few records from Montezuma County and
one from Mesa County (Fig. 2).
Abronia nana var. nana in Colorado is! only from gypsum outcrops in the Sinbad Valley in extreme
western part of the state, on the Mesa-Montrose Eun) ime "his is the easternmost edge of its distribution
range. It is a very distinctive species with acaulescent stems, and the entire plant is usually extremely viscid
glandular. The fruit of A. nana var. nana is conspicuously viscid glandular and also winged. The five wings
are broad, flat, and not dilated at the top (Fig. 1D).
Abronia bolackii Atwood, Welsh & Heil is a newly described species of Abronia endemic to gypsum soil
in Ge Juan County, New Mexico (Atwood et al. 2002). It is delimited from A. elliptica based on the presence
fewer flowers per head (15-25 opposed to 25-75). However, the fruit and habit of A. bolackii
are identical to that of A. elliptica. Specimens of A. elliptica with rhizomes have been collected as far north
as San Juan County, Utah [Utah: San Juan Co.: E base of Comb Ridge just N of Hwy US 613, 1 Jun 1999, L.
Yeatts 4251 (COLO). Richard Spellenberg (pers. comments) has also observed rhizomatous A. elliptica plants
throughout its range from northcentral Arizona and northwestern New Mexico to northeastern Utah and
L er including western Colorado. Welsh (2003) st that gnition of the occasional
ts (of A. elliptica, included within his description of A. fragrans) at any taxonomic level seems
enel. In addition, several specimens of A. elliptica have as few as 19-24 flowers per head [Colorado:
Moffat Co.: ca. 2.5 mi E of mouth ai Irish Canyon, 7 Jun 1983, Baker & Kennedy 83-32 (CS); Colorado: Mot-
fat Co.: Junction of Green and Yampa rivers, 8 Jul 1945, H.D. Harrington 1480 (CS); Colorado: Mesa Co:
Rabbit Valley, sandstone outcrop in sandy soil, 21 May 2004, Wm. F. Jennings s.n. (CS)]. Finally, the range of
A. bolachii is well within the range of A. elliptica. Consequently, the status of A. bolachii as a species appears
unjustified, and should be included in synonymy under A. elliptica.
The following key includes the common name, scientific name, synonyms (if applicable), ecology and/
or distribution, elevation range, flowering time, and occurrence on the eastern or western slope of Colorado
(designated by an E or W, respectively) for each species.

INIT RODUCI MUN
The genus Chenopodium L. (Chenopodiaceae) in its traditional wide circumscription has long been sus-
pected to be an unnatural (polyphyletic or paraphyletic) union of taxa belonging to different phylogenetic
lineages. Consequently, many segregate genera and infrageneric taxa of various ranks were described and
accepted within this group 9r various authors (see an overview in Scott, 1978). The genus Dysphania R. Br.
during its turbulent t an latural history also experienced numerous shifts: from a single
genus of a separate family Dysphaniaceae (Pax & Hoffmann 1934) or a representative of Illecebraceae or
Caryophyllaceae— to a mere section of Chenopodium s.l. (Aellen 19302, 1930b; see also di ion in: Eckardt
1967; Mabry & Behnke 1976; Scott 1978; Wilson 1983, 1984; Mosyakin & Clemants 2002, and references
therein). The present article continues a series of our publications (Mosyakin 1993; Mosyakin & Clemants
1996, 2002; Clemants & Mosyakin 2003) on Chenopodium Ge s.l. ana its Ne
Earlier (Mosyakin & Clemants 2002) we justifie di the t y placed in Chenopodium
L. subg. Ambrosia A.J. Scott, commonly called Rus HEHGOIDEER ed to as glandular chenopods, to the
genus Dysphania, and validated new t | preparat ion for t] t of the genus in
Flora of North America north of Mexico (Clemants & Mosyakin 2003). At that time we made 18 new combina-
tions, including 11 at the species level, 4 at the section level, and 3 at the level of subsection. Nomenclatural
changes were essentially limited to taxa occurring in North America (both native and introduced), leaving
a number of glandular chenopods yet to be formally transferred to Dysphania.

The t j ] latural decisions t landular cl 1s withi expanded Dysphania
were further discussed in the Dr. Sci. dissertation of Mosy akin 2003). The genus Dysphania circumscribed
so as to include all glandular taxa of Chenopodium has been accepted for the — of Chenopodiaceae
in Flora of North America north of Mexico (Clemants & Mosyakin 2003) and Flora of China (Zhu Gelin, Mos-
yakin & Clemants 2003). At least one additional transfer of a species from Chenopodium to Dysphania (D.
pdseudomul inis (Murr) EE Sr Lambinon) has been made (Verloove & Lambinon 2006) since then.
Here we validate new tions in Dysphania for other species not transferred to that genus earlier.
We refrain here from mal ific conclusion on phylogenetic relationships within Dysphania. However,
judging from a thorough dni os of relevant literature, our herbarium and field experience, studies of mor-
phology and biogeography of glandular chenopods, we firmly believe that Dysphania in the new circum-
scription is a natural phylogenetic unit distinct from Chenopodium s.s. Since 2002 it was partly confirmed
by molecular phylogenetic studies.

Scott, 1978). In particular, Kadereit et al. (2003, p. 976) indicated: “In Chenopodieae III, a close e
of the Eurasian species Chenopodium botrys and Teloxys aristata, and of the Australian species Chenopodium
cristatum and Dysphania glomulifera, is supported by the presence of multicelluar glandular hairs (type 8
in Carolin 1983). By that character, they fit into subgenus Ambrosia (Scott 1978; Simón 1996). <...> These
results confirm the proposal of Mosyakin and Clemants (2002) to transfer Chenopodium subg. Ambrina [sic!
—S. M. & S. C] to Dysphania <...>.” In a study of the origin and age of Australian Chenopodiaceae Kadereit
et al. (2005, p. 74) indicated that "[rlecently, Mosyakin and Clemants (2002) used morphological characters
to separate subg. Ambrosia from Chenopodium, and included it in Dysphania. This last view is strongly sup-
ported by our results.”
Other options alternative to our wide circumscription of Dysphania would be to recognize several gen-
era, for example, Teloxys Moa. (including only Chenopodium aristatum L. = T. aristata (L.) Moq., or also other
related taxa), Roubieva Moq. (mainly an American group, which may be recognized either in the original
sense of Moquin-Tandon (1834), or with addition of other American taxa), the Australian group previously
placed in Chenopodium sect. Orthosporum R.Br., and Australian Dysphania in its traditional circumscription.
These groups, corresponding mainly to sections in various classification schemes of Chenopodium s.l., seem

In the present article we validate 21 new
the transfers of glandular-pubescent species to Dysphania. A moderately narrow —€— concept is applied,
which is mainly consistent with prevalent taxonomic treatments of “glandular chenopods” and species of
Chenopodium s.l. We admit that many species of the considered groups are in need of further revisions and
more detailed studies, but that should not preclude making available new combinations in Dysphania for

them. In addition to our experience and herbarium studies of these taxa, we especially consulted with and
relied upon the basic taxonomic publications by Aellen (19302, 1930b, 1933, 1973), Aellen and Just (1943),
Wilson (1983, 1984, 1987), Simón (1995, 1996, 1997), as well as other relevant works (Voroshilov 1942;
Scott 1978; Carolin 1983; Weber 1985; Palomino et al. 1990; Kühn 1993; Schwarzová 1993; Uotila 1997,
2001).
VALIDATION OF THE NEW COMBINATIONS
1. Dysphania sect. Orthospora (R. Br.) Mosyakin & Clemants, Ukrayins'k. Bot. Zhurn. 59:382. 2002.
Several names of putative hybrids between Australian taxa belonging to ape sect. EE were
published (Aellen 1933, 1961; Wilson 1983, 1984). However, since their t
and their hybrid origin is mostly in need of confirmation, we refrain from making here any new combina-
tions for hybrids.

Dysphania saxatilis (PG. Wilson) Mosyakin & Clemants, comb. nov. Basionya: Chenopodium saxatile PG. Wilson,
Nuytsia 4:179. 1983
The last species was described by Wilson (1983) from Western Australia as C. saxatile. The author of the
species noted that “Isluperficially this species would appear to be related to the 4-merous species in the
genus Dysphania (e.g. D. rhadinostachya) but in seed character it is obviously different, being very similar
to Chenopodium pumilio and its allies of the section Orthospora. Yet even here its placement is uncertain
since the other species of this section have flowers arranged in compact glomerules, have one stamen, and
normally a 5-merous perianth." (Wilson 1983, p. 180). Wilson also compared his species with members
of the Chenopodium botrys group (which evidently differ from C. saxatilis in having 5-merous perianth and
horizontal seeds) and section Margaritaria (which has whitish subglobose, as well as glandular, hairs, and
some other distinctive characters, see Brenan 1956), and concluded that *it appears that C. saxatile does not
fit satisfactory into any of the presently recognized groups." P.G. Wilson refrained from describing a new
monotypic section and instead expanded the circumscription of Chenopodium sect. Orthosporum to include
his species. Pending further research, we keep the species in Dysphania sect. Orthospora.
2. Dysphania sect. Adenois (Moq.) Mosyakin & Clemants, Ukrayins'k. Bot. Zhurn. 59:382. 2002.
In our previous puplicanans (Mosyakiii & Clemants 2002; Clemants 2 ME 2003; Zhu Gelin et al.
2003) we mentioned that opinions vary widely regarding the proper st in this section, with
some authors ae Es a few species, including ext ly polymorphic Chenopodium ambrosioides L.
with infraspecific taxa, \ t] l (up to 12) ly ci il
(Aellen 1929, 1961, 1973; Aellen & Just 1943; fotos diy 1942: Simón 1996, 1997; tom 1997). Gam ance
the same author (notably Aellen) in different periods of his work was of differing opinions regarding the
number of species related to C. ambrosioides. We believe that taxa in this group differ from each other not
less than many generally recognized species of Chenopodium s.l. (subg. Chenopodium), especially in the C.
album group. Numerous infraspecific entities were recognized in C. ambrosioides and some other variable
taxa. In the present article we are concerned with the species-level taxonomy, and thus for the time being
refrain from making any new infraspecific and infrageneric combinations.

The name of this subsection within the genus Chenopodium is often incorrectly cited as a combination Che-
nopodium subsect. Botrys (W.DJ. Koch) Aellen & Ijin. Since the name published by Koch is illegitimate,
the above subsectional name should be attributed to Aellen and Iljin, who provided its description only in
Russian, but also included a reference to the earlier pre-1935 publication and description by Koch, which
makes their subsection validly published.

An arctic—alpine race of Equisetum arvense L. has in recent years been accepted as subsp. boreale (Bong) A.
Love (e.g., by Ollgaard 2000). Schónswetter et al. (2001) argued that the name “boreale” is Eege for
the race in question. It is based on a Bongard plant from Sitka in soutl Alaska req morph
within subsp. arvense, differing from the arctic and high alpine plants in many morphological aiies The
next available name is Wahlenberg's var. alpestre, and a combination as subspecies is proposed here.

Northern North American plants of Stuckenia filiformis (Pers.) Börner differ from the main race by their
broader leaves and more congested inflorescences. Such plants have been considered by authors (e.g., Hul-
J. Bot. Res, Inst. Texas 2(1): 433 — 446. 2008

tén 1968a; Cody 1996, 2000) as subsp. or var. borealis, based on Rafinesque's Potamogeton borealis from the
St. Lawrence River region. Les and Haynes (1996) synonymized Potamogeton borealis with the Norwegian
Potamogeton marinus L. f. alpinus Blytt, Norges Fl. 1:370 (1861), described from southern Norway, and they
raised f. alpina to subspecific rank as the accepted name for the North American subspecies. Haynes et al.
(1998) transferred Potamogeton filiformis to the genus Stuckenia, which we accept. Haynes and Hellquist
(1998) reported subsp. alpina as restricted to North America and perhaps northeastern Asia, in spite of it
being described from Norway.
Blytt's f. alpinus has not been lectotypified. The syntypes (O!) from the six sites listed in the protologue
are all from southern Norwegian mountain valleys. They have not been studied by Les, Haynes or Hellquist.
Les and Haynes (1996: 390) stated, when they synonymized Norwegian ‘alpina’ and North American ‘borealis’,
with PROS. for the former, that they had not seen type material (P) of ‘borealis’. Neither have we, but when
i y of Blytt's Norwegian f arma 5 Mol Moni American paian we Ge Hen different.
We consider the N lant tane f European S
as an EE race peda, whereas we consider the North American plant an aceptable race. We
the North American name "borealis" for the northern North American plants. This
taxon is characterised by two differential characters as given by Haynes and Hellquist (for subsp. filiformis
vs. subsp. alpina, slightly modified here): leaves 0.2-0.4 mm vs 0.5-0.8(-1.0) mm broad, and infrutescence
strongly interrupted and extending up to 4 cm vs more compact to somewhat interrupted and extending

not
only up to 2 cm.

Greene (1980, 1984) recognized two races in the very widespread Calamagrostis purpurascens: var. purpura-
scens from northern Siberia to northern Greenland (and recently found also on Svalbard) and var. laricina
restricted to northeastern Canada and southern and western Greenland. The latter race is characterized by
being short-rhizomatous and by having awns not distinctly exserted from the spikelet. Sorensen's descrip-
tion of C. poluninii in 1954 was made without reference to (and probably while unaware of) Louis-Marie's
earlier description of var. laricina in 1946. Greene seems to have been the first to compare the types and
recognize that the two names apply to the same plant.
The southern and western Greenland plants named C. poluninii are an extension of the northeastern
North American C. purpurascens var. laricina. As this is a major geographical race, the rank of subspecies is
preferable to variety, and a new combination is proposed.

Within the polymorphic, circumpolar Puccinellia phryganodes, Sorensen (1953) informally named four enti-
ties as “types”: a fertile, tetraploid “Beringian type” (2n = 28) and three asexual types: a triploid “Greenland
type” also widespread in arctic North America (2n = 21), a tetraploid “Spitsbergen—Novaya Zemlya type”
restricted to these islands, and a “Siberian type” ranging from northeastern Norway (triploid) Maie un arctic
Russia and Siberia to ica (tetraploid). Serensen (1953) d trated anatomical and
differences in addition to the ploidy differences. We prefer to consider Sgrensen's types major UM
cal races, i.e., subspecies, of a morphologically coherent species phryganodes. Subsp. neoarctica is a sterile
stoloniferous race that reproduces by detached shoots

Tzvelev (1964) made a mistake in the basionym, replacing “sibirica” with “asiatica” when publishing Puc-
cinellia phryganodes subsp. asiatica. At the rank of subspecies, the epithet “sibirica” (Hadat & Love in Love
& Lóve 1961) has priority over “asiatica” (Tzvelev 1964).

The small genus Vahlodea (a segregate of Deschampsia) is disjunct in three very distant regions: around
the North Atlantic, the northern Pacific, and in southernmost South America. From one to four species or
subspecies have been proposed. Tzvelev recognized, besides the South American V. magellanica (Hook. f.)
Tzvelev, three northern species: V. Se M ii ia pd V. onem The amphi-Atlantic V. atropurpurea
s. str. is fully allopatric with the two Pacifi ically from both of them. The most
evident difference between the mainly ees Asian plant Y feos or V. POramusmténsis and the
North American one (V. latifoli that the Asian plant has hai merican
plant has glabrous leaves. They also ice in senal habit, but there are or intermediates, especially in
southern Alaska. Soreng et al. (2003) recognized only one species with two subspecies: subsp. atropurpurea
(including both V. latifolia and the South American V. magellanica) and subsp. paramushirensis. The solution
chosen for the Panarctic Flora Checklist is two northern species: one amphi-Atlantic (V. atropurpurea) and
one amphi-Pacific (V. latifolia), the latter with two subspecies (subsp. latifolia and subsp. paramushirensis)
inasmuch as the entities intergrade. This necessitates the new combination.

The widespread Bistorta officinalis Delarbre s. lat. is disjunct tane and arctic. The northern montane and
arctic plants differ from non-arctic European Bistorta officinalis s. str. in several characters, and they should
be accepted as different race(s) or species. Freeman and Hinds (2005) accepted the northwestern North
American and northeastern Asian plant as B. plumosa (Small) Greene. Petrovsky (1966), treating the plants
for arctic Russia as races of Polygonum bistorta, assigned the plants from northeastern Europe and northern
Siberia (Taimyr) to subsp. bistorta (= subsp. officinalis) and those from northeastern Sil (Anabar T ne
to the Chukchi Peninsula to subsp. ellipticum. He considered the North American si ibsp. pl sa as different
from both of these. We agree with this division of the arctic Russian material but not ih the application of
the names. Tzvelev and Yurtsev (pers. comm.) assumed the "elliptica" name to belong to the western entity.
Polygonum ellipticum was described from non-arctic parts of the Lena River area. In the Arctic, the limit
between the western and the eastern entities runs through the Taimyr, but further south in Siberia and the
Russian Far East this otherwise western arctic entity occurs in the mountains all the way eastward to the
Okhotsk Sea. We therefore recombine Polygonum ellipticum within Bistorta and accept it as the name for the
northern Russian and northwest Siberian plant. We consider the northeast Siberian and northern Russian
Far East plants as indistinguishable from the North American Bistorta plumosa, in spite of a suggested dif-
ference in chromosome numbers.

i
We find the races distinct at the level of subspecies. In three areas of co-occurrence (in the lower Lena River
area of northern Siberia, in eastern Chukotka, and in northern Alaska—northwestern Canada) they are
fully distinct in nature. Subspecies furcata then becomes the most widespread of the races. Silene furcata
Raf. is not typified, but this race is the only one present in the Hudson Bay—Labrador area from where it
was described. A subspecific combination based on this name is proposed. This was also the opinion of
Tzvelev (2000).

inclusion of M. macrosperma within S. soczavana, not within S. uralensis. According to the material we have
inspected, Silene soczavana var. macrosperma is a widespread taxon from eastern Chukotka and the north-
ern Bering Sea islands northeast to the Alaskan North Slope and south and southeast to Kodiak Island and
northern British Columbia.

We accept Ranunculus subborealis Tzvelev (the name replacing R. borealis Turcz. in a northern context) as a
species separate from R. acris L
There can be two different interpretations of the name “pumilus” and two different meanings derived
from them. The older meaning is Nordic and based on Ranunculus acris var. alpha Wahlenb. 1811, formal-
ized as R. acris var. pumilus Wahlenb. 1824. Nurmi's typification assigns this name to a Scandinavian alpine
subglabrous race more closely related to R. subborealis than to R. acris. Intermediates are frequent between
subsp. pumilus and other races of R. subborealis but not between subsp. pumilus and R. acris.
438
The other meaning is Russian and based on R. acris var. pumilus “Wahlenb. ex” J. Fellm., Bull. Soc.
Naturalistes Moscou 8:271. 1835. If Fellmann really based his variety on Wahlenberg's var. alpha, then it
is homotypic and a superfluous combination antedated by Wahlenberg 1824. Thus the Nordic meaning as
established by the typification of Nurmi is also valid for Fellmann’s variety. If not, var. pumilus sensu Fell-
mann is a later homonym. From the descriptions in several Russian floras, the application of the name var.
pumilus J. Fellm. in Russian areas is different from that of the name var. pumilus Wahlenb. in Nordic areas.

This race connects morphologically with Ranunculus subborealis s. str. in northeastern Fennoscandia, with
transitions in the Norwegian provinces of Troms and Finnmark and in northern Sweden and Finland.
Transitions towards R. acris s. str. are rare. Subspecies villosus is the dominant entity of the R. acris group

The eastern Canadian and Greenlandic Papaver labradoricum resembles P. lapponicum (Tolm.) Nordh. and P.
radicatum Rottb. and has been considered as a subspecies of either one of these (e.g., Fedde 1936; Knaben
1958, 1959a, 1959b). The assignment to P. radicatum has been justified by morphology (Kiger & Murray
1997), that to P. lapponicum by sharing the same octoploid chromosome number (2n - 56), whereas P. radi-
catum is decaploid. In an unpublished study by Solstad et al., based on Structure analysis of AFLP DNA
markers, P. labradoricum is a distinct entity (species) which joins comparatively closely with a Beringian
species (P. cf. detritophilum) out is M TE from the Atlantic European P. radicatum and the amphi-Atlantic
P. lapponicum. Several res are also shared with the Beringian species, but P. detritophilum
is hexaploid (2n = 42) A separon is further supported by the low fertility found by Knaben (1959b) in
crosses between P. labradoricum on one hand and P. lapponicum and P. radicatum on the other, at the level
of crosses between species according to Knaben. Papaver labradoricum is probably an allopolyploid with a
complicated parentage, as are P. lapponicum and P. radicatum.

in the group. We are able to recognize the arctic entities on morphological criteria, and transitional forms
have not been documented. Arabidopsis petraea s. lat. also differs in some morphological characters from A.

Saxifragaceae
The phylogenetic analyses of Soltis et al. (1996, 2001) show that there are two major branches of genera
in Saxifragaceae, and that a large segregate of traditional Saxifraga L., i.e., Micranthes Haw. (s. lat.) together
with, e.g., Chrysosplenium L., belongs in a different branch from Saxifraga s. str. The molecular evidence
makes it difficult to retain Micranthes within Saxifraga, and (like Brouillet & Gornall 2007) we accept it as a
separate genus for the Checklist. Several combinations within Micranthes have been made in earlier times,
and Brouillet and Gornall (2007) made the combinations they needed for their treatment for Flora of North
America. This treatment does not cover the Asian taxa, and also for a few North American taxa we prefer
another rank than chosen by Brouillet and Gornall.

There is also a suggested ploidal difference. All reports of comparatively low chromosome numbers (2n =
56 and 63) are from northeastern Yakutia and Chukotka where these numbers are reported together with
the prevalent much higher numbers everywhere else in northern and arctic regions (2n - 100-120). From
Alaska, only highly polyploidal counts are reported (2n = >100 and 112), but these reports are partly from
localities outside the range of subsp. longifolia as we have recorded it.

The names subsp. longifolia and subsp. czukczorum were published one year apart (1980 and 1981),
and we assume that they represent the same taxon and that the authors were unaware of the other publica-
tion.
On the American side, subsp. longifolia is common in western Alaska north and east to the western
Brooks Range (on the north coast as very rare east to Demarcation Point) and to the Kobuk and Yukon river
valleys. In southwestern and south-central Alaska it is the exclusive race, e.g., in the Goodnews Bay area,
Alaska Peninsula, and on Kodiak and smaller offlying islands.

Micranthes redofskyi is a diploid (2n = 20) belonging in sect. Micranthes together with at least three assumed
close relatives: the seed-reproducing, amphi-Atlantic M. stellaris (L.) Galasso, Banfi & Soldano (2n - 28), the
also seed-reproducing, Pacific North American M. ferruginea (Graham) Brouillet & Gornall (2n = 20), and
the bulbil-reproducing, arctic circumpolar M. foliolosa (R.Br.) Gornall 2n = 40—64). All four species are mor-
phologically distinct, but M. foliolosa has been assumed (Zhmylev in Elven et al. 2007) to be: *... a complex
of 2-3 entities formed as a result of polyploidy of pseudoviviparous races of Saxifraga stellaris, S. redofskyi

inherited from the parental entities. Arctic plants of Micranthes foliolosa are morphologically much closer to
M. redofskyi than to M. stellaris or M. ferruginea. An unpublished investigation based on AFLP DNA mark-
ers and comparing these species (A. SEH Salzburg) connects M. foliolosa sampled throughout the Arctic
closely to M. redofskyi (and not to M. stellaris). The more floriferous populations of M. foliolosa are found in
he Beringian regions, with lower chromosome numbers than the majority of the plants, overlapping in range
with M. redofskyi and close to the range of M. ferruginea. Micranthes redofskyi is restricted to northeastern Asia

sidered it a subspecies, as we do, and recombined it as subsp. subarcticum, probably unaware that the epithet
decumbens, even if not available for a species, is available and has priority for a subspecies. We accordingly
make a recombination on the priority name.

Vaccinium uliginosum L. is polymorphic as described by Young (1970). Komarov's Vaccinium vulcanorum
is, according to Tolmachev and Yurtsev (1980), a prostrate-pulvinate dwarf shrub with small, imbricate,
rotundate leaves persisting in winter, and globose berries. In a phylogenetic analysis by Alsos et al. (2005),
the “vulcanorum” entity is a central node from which both an amphi-Pacific and a circumpolar clade emerge.
Both phylogenetic and morphological evidence support the taxon vulcanorum as a race, preferrably as a

The entities of the Gentianopsis detonsa—barbata group in northern North America are still insufficiently
studied, in spite of two revisions (Gillett 1957; Iltis 1965). They are rare taxa, restricted in their ranges and
often disjunct. The “raupii” entity has | considered a separate species or a subspecies of Gentianella / Gen-
tianopsis detonsa. Hultén (1968b) accepted Gentiana raupii as a separate species in northwestern Canada but
said that it is “similar to G. barbata, but with fewer stem leaves; calyx rounded at base; corolla tube broadly
obconic, the lobes broad, rounded". We support that view and hereby assign "raupii" to Gentianopsis barbara
as a regional race. It occurs mainly along the Mackenzie River, and the entire range is within the glaciated
areas. This is an entity that at some time (most probably postglacially) was able to differentiate in isolation
from the main body of Gentianopsis barbata.
Asterac
Achillea alpina L. subsp. multiflora (Hook.) D.E Murray & Elven, on E ME nov. Bastonvm: Achillea multiflora
Bor.-Amer. 1:318. 1833. Type: CANADA: "Throughout the wo y, klin,” (HOLOTYPE:
5 ia multiflora (Hook.) Tzvelev in Jurtz., Fl. Arct. URSS 10:107. 1987.
The North American representative of the Achillea alpina complex has been treated in most northwestern
North American works (e.g., Hultén 1968a; Cody 1996, 2000) as A. sibirica Ledeb. Both names, alpina and
sibirica, are based on Asian plants. Trock (2006) applied the name A. alpina without discussion for the
North American plant. Russian authors have mostly treated the entities of the A. alpina complex as several
species. Rank as largely allopatric subspecies of Achillea alpina is the better solution. The northwestern
North American plants differ from the northeastern Asian ones in some quantitative features: capitulae
more numerous, ligules smaller, and leaves slightly more dissected. We hereby recombine A. multiflora as
a subspecies of A. alpina.
The Achillea alpina complex has been considered part of the segregate genus Ptarmica (e.g., Yurtsev
ri ] AA Al kh: el HET | D ti 443
1987). Acceptance of Ptarmica as a separate genus is untenable according to phylogenetic evidence (Guo et
al. 2004)

Artemisia alaskana Rydb., N. Amer. Fl. 34(3):281. 1916. Tyre: U.S.A.: ALASKA: Yukon River, Nulato-Nowikakat, 23-27 Jul 1889,

Hultén (1968b) compared thwestern North American Artemisia
A. kruhsiana and considered them related but specifically distinct. Artemisia “o was described with
three allopatric to a SE in northeastern Ásia E 1987). Korobkov (pers. comm.)
indicated that A. alaskana lly closest to A. kruhsia bsp. multisecta (Leonova) Korobkov.
We consider A. alaskana to be des enough to A. kruhsiana to be best considered a subspecies of the latter
(see also Tkach et al. 2008 wherein A. kruhsiana and A. alaskana were very close in the phy logeny). In our
opinion, the closest relationship is found with the Chukotkan subsp. kruhsiana. There is, however, an ap-
preciable gap between the westernmost geed occurrence of subsp. alaskana and the easternmost Asian
occurrence of subsp. kruhsiana, as th bsent from all of Chukchi Peninsula. We therefore propose
subsp. alaskana as a fourth subspecies gi A. kruhsiana.

Transfer of Senecio hyperborealis to Pachera necessitates the new combination. Pachera hyperborealis s. str. is
diploid (Packer 1972, northwestern Canada, 2n 2 46; Yurtsev & Zhukova 1972, northeastern Asia, 2n = 48).
Subspecies wrangelica, on the other hand, is hexaploid (Zhukova & Petrovsky 1987, Wrangel Island, 2n =
138). This high number is more in accordance with the wide range of numbers found in the closely related
P. heterophylla (Fisch.) E. Wiebe (= Senecio cymbalaria Pursh, Senecio resedifolius Less.).

The new combination is necessitated by the transfer of Leontodon ae L. to Mie EE Scorzoneroides
Moench (cf., Sell & Murrell 2006). The provenience and characters of I tensis is not
known to us, but the customary use of the name pratensis in northern Europe is for Tue Blast considered
here. The Nordic plants currently assigned under var./subsp. pratensis include Linnaeus' Hieracium taraxaci
and are different from the central European alpine plants.

Solidago multiradiata Aiton is widespread and polymorphic. The plants around the Bering and Chukchi seas
in eastern Chukotka and western and southwestern Alaska constitute the westernmost extension of the
range for S. multiradiata and differ in several quantitative features. Hulten (19682) accepted a variety, var.
arctica. Russian authors (e.g., Korobkov 1987) have instead treated it as a separate species, 5. compacta. We
prefer to see S. compacta or var. arctica as a regional race, i.e., a subspecies. It might be uniformly tetraploid
(2n = 36), as indicated by Lóve and Lóve (1975), but both diploid and tetraploid counts are known from S.
multiradiata s. str.

The Capitan Mountains are the most northeastern range in the greater Sacramento Mountains complex, a
group of mountain ranges in Lincoln and Otero counties of south-central New Mexico which also includes
Sierra Blanca, Carrizo Mountain, and the Sacramento Mountains proper. These mountain ranges include
the highest point in the southern half of New Mexico, Sierra Blanca Peak at 3,649 m, and contain large
areas over 2,500 m elevation. There are no similar mountain ranges nearby. The nearest peak exceeding
3,000 m is South Baldy in the Magdalena Mountains, ca. 190 km to the west-northwest, while the nearest
peak equalling Sierra Blanca's height is Tesuque Peak in the Sangre de Christo Mountains ca. 320 km to
the north. Consequently, there is a well-developed high-elevation flora in the Sacramento Mountains com-
plex that is isolated from other areas with similar floras. This area contains some of the most southeastern
populations of typical members of the Rocky Mountain flora, such as Picea pungens Engelm. and Abies bifolia
A. Murr. and is home to 21 endemic plant taxa. Most botanical exploration in the area has been conducted
in the Sacramento Mountains proper and on Sierra Blanca. The Capitan Mountains and Carrizo Mountain,
both granite laccoliths on the northern end of the Sacramento Mountains complex, are comparatively dif-
ficult to access and distant from centers of botanical research. Their floras remain poorly known. It is thus
no coincidence that the Capitan Mountains yielded the most recently described of the endemics of the
Sacramento Mts. complex, Astragalus kerrii Knight & Cully (Knight & Cully 1991), as well as the presently
described species.
The endemic flora of the Sacramento Mountains complex has traditionally included a Heuchera, H.
wootonii Rydb. of section Parvifoliae (Small & Rydberg b Ge & A d Rosendahl et al. 1930).
This species, however, has recently been reported iption is uncertain
(New Mexico Rare Plant Technical oun 1999; B. Shipes, personal communication). With the pron -
described H. woodsiaphila, the Sacramento Mountains complex gains an endemic Heuchera at the sam
that it risks losing one.

Etymology.—The specific epithet refers to the close association of this species with Woodsia plummerae
Lemmon, which is ubiquitous at populations of H. woodsiaphila and is often the most abundant vascular
plant in the SHOE vicinity.
Phenology.—Specim n llected in July and August include both mat fruit d flowers at anthesis
Geography m habitat —Heucl tly known only from Capitan Peak at the eastern
end of the Capitan Mountains in Lincoln County, New Mexico (Fig. 3), where it has been observed from
2,550 to 2,900 m in elevation along the Capitan Peak Trail, Lincoln National Forest Trail #64. It is found at
locally moist sites on north or northeast, stable, forested granitic talus, usually under cover of Pseudotsuga
menziesii (Mirb.) Franco or Abies concolor Lindl. & Gord. and in association with Woodsia plummerae. These
moist sites are many, but small and scattered. Much of the forest in this area has burned recently, and H.
woodsiaphila appears to be equally abundant in burned and unburned areas.
Distinction from other Heuchera. Heuchera woodsiaphila is very similar to members of Heuchera section
Holochloa Nutt. subsection Cylindricae Rydb. Like other members of subsection Cylindricae, it has elongate
(5-8 mm in the subsection), white or whitish, actinomorphic or slightly zygomorphic, apetalous flowers
with campanulate hypanthia and long (2.5—6 mm in the subsection), erect sepals. Heuchera woodsiaphila is
widely disjunct from other members of the subsection, which are present in the northwestern United States
and adjacent Canada. The nearest known populations of H. cylindrica Dougl. are in northeastern Nevada
more than 900 km to the northwest.
Taxonomy of subsection Cylindricae is uncertain. The subsection includes up to 9 taxa at varietal to
specific ranks, all of these taxa apparently intergrading to a greater or lesser extent (Calder & Savile 1959;
Alexander, A i f Heuc! f New Mexi 451
Rosendahl et al. 1936). In comparatively recent floras of the northwestern United States and adjacent Canada,
subsection Cylindricae is generally treated as two species: H. chlorantha Piper and a highly polymorphic H.
cylindrica (e.g., Douglas et al. 1991; Hitchcock & Cronquist 1973). Based on the most recent monographic
treatment of subsection Cylindricae (Calder & Savile 1959), H. woodsiaphila is most similar to H. saxicola E.
Nelson and H. cylindrica Dougl. vars. cylindrica and orbicularis (Rosend. et al.) Calder & Savile. It differs from
the former in lacking dense, viscid pubescence, in having leaves with cordate bases, and in having smaller
bracts within the inflorescence. Heuchera woodsiaphila differs from the above-mentioned varieties of H. cy-
lindrica in having shorter scapes (8—20 vs 22—70 cm) and usually having sterile bracts with well-developed
blades. Although Calder and Savile (1959) do not discuss characters of the androecium or gynoecium in
depth, these are described in detail by Rosendahl et al. (1936). Following the latter treatment, H. woodsiaphila
also differs from the known members of subsection Cylindricae in having shorter anthers (0.7 vs. 0.9-1.5
mm) and longer true closed styles (1-1.5 vs. < 0.5 mm). To aid in distinction of this species from others in
New Mexico, a key is provided below.

Although production of new comprehensive keys for subsection Cylindricae best awaits revision of the group
and is thus beyond the scope of the present work, the key of Calder and Savile (1959) can be modified to
accommodate H. woodsiaphila by replacing the first half of couplet “2” with the following:

Other specimens.—Of the other major regional herbaria only UNM and UTEP have specimens of Heuchera
from the Sacramento Mountains complex. On viewing the collections of these herbaria no additional speci-
mens of H. woodsiaphila were found.
Discussion.—Although a conspicuous component of the flora at Capitan Peak, H. woodsiaphila was still
unknown when I stumbled upon it while hiking the peak in 2006. Although I quickly found S. Chaddie's
452
1995 i (also from Capitan Peak but misidentified as H icana) and determined it was the same
A
as m» new collection, I could not identify these plants. Discussion with other botanists in the state, notably
Robert Sivinski, quickly made it clear that this was not a species known from New Mexico but left open the
possibility that it was a species well-known elsewhere. In the comprehensive monograph of Heuchera by
Rosendahl et al. (1936), H. woodsiaphila clearly falls into Heuchera section Holochloa subsection Cylindricae.
Although E deiere eg is readily distinct from taxa of subsection Cylindricae as they are described in the
of Rosendahl et al. (1936) and Calder and Savile (1959), the confused nature of this
sube don makes it difficult to ascertain the limits of the considerable variation found in both the named
taxa and their various hybrids. The proper status of H. woodsiaphila is thus difficult to determine at present.
Although it could be argued that H. woodsiaphila is better treated as a variety of H. cylindrica, hiding varia-
tion within species tends in practice to obscure it or give the impression that it is unimportant. Further,
this would not in any way reduce the taxonomic uncertainty in subsection Cylindricae, but would merely
maintain the same uncertainties at a different taxonomic level. Unfortunately an adequate resolution to this
problem must await a modern revision of the BUDE.
Although H. Isiaphila i imil hol llyt | f subsection Cylindricae, the pos-
sibility that this species may en bom hybridiza done kiun New Mexican Heuchera and be only
convergent with members of subsection Cylindricae should not be excluded. Leaves of H. woodsiaphila are
identical in appearance to those of some specimens of the polymorphic H. rubescens, a member of section
Rhodoheuchera R. B. & L. subsection Rubescentes Rydb. and, although difficult to distinguish in technical
Ea
characters, seem subjectively rather different from those of subsection Cylindricae. Furthermore, most char-
acteristics in which this species differs from New Mexican members of section Holochloa, including the long
sepals, short scapes, and well-developed, leaf-like sterile bracts of the scape, can be found in H. rubescens.
Molecular phylogenetic analyses will probably be necessary to ascertain the affiliations of H. woodsiaphila
with any certainty.
The highly restricted distribution of H. woodsiaphila is also noteworthy. The apparent limitation of this
species to high-elevation, forested talus may explain this limited distribution. On the Capitan Peak Trail,
H. wootonii occurs in similar habitat to H. woodsiaphila but at lower elevations (1,950 to 2,400 m). On trips
to the otherwise geologically and floristically similar mountains nearby, Sierra Blanca and Carrizo Moun-
tain, I could find neither high-elevation, forested talus nor H. woodsiaphila. Instead, on these tains the
talus is either bare or has only low, tangled vegetation and H. wootonii occurs to at least 3,000 m. In these
mountains, H. wootonii is often found near Woodsia neomexicana Windham or W. phillipsii Windham. Here
W. plummerae, which is typically present with H. woodsiaphila, is conspicuously absent. Both the Capitan
Mountains and nearby Carrizo Mountain are poorly explored botanically, however, and H. woodsiaphila may
well have a broader geographic or ecological distribution than is presently known.

The state of HE was ad from the state of Goiás in 1988, and since then the Brazilian government
encouraged its econom t through the creation of new cities and new roads, and by stimulating
immigration from other Prom states. For example, Palmas, the state capital and the newest city in Brazil,
in 2007 has already grown to more that 200,000 inhabitants, and many other new urban agglomerations
have been founded throughout the state during the last decade. As for the vegetation, the southern por-
tion of the state is located within the Brazilian Savannah (Cerrado Biome). Whereas, the central-northern
portion of the state is an area of transition between the Savannah and s Amazon Basin, with a floristic
composition from both biomes and unique to this vegetation. Thi larly true for the floristic
composition of the gallery forests geg water courses flowing northwards, which act as migratory routes
connected with the Amazon Basin. This region continues to be botanically little-known, and only recently
has received some attention through several botanical expeditions organized by local institutions. At the
same time, the entire state is under rampant anthropic pressure due to aggressive and extensive farming,
construction of new state roads leading to remote areas, and massive human migration that took place dur-
ing the last two decades. In addition, even the potentially protected areas are not safe from this ongoing
environmental destruction, as it is common to see large herds of cows grazing among the vegetation of the
state and national parks present in this state.
During the preparation of the Rubiaceae treatment for the Flora de Goiás e Tocantins, three interesting
collected in the forests of the central-
species of Ixora were encountered. All of them are understory shru bs
northern portion of the state of Tocantins. After consulting all the available literature dedicated to South

the specimens present in herbaria with large Brazilian collections (see acknowledgments), it was concluded
that they are, in fact, new to science. One species, Ixora congestiflora Delprete is known from two collections,

Maranháo, near the Tocantins River, in semideciduous and gallery forests with Amazonian influence. The
second species, Ixora araguaiensis Delprete is also known from two collections from northern Tocantins,
near the Araguaia River. The third species, Ixora irwinii Delprete, is known from a few collections from gal-

Distribution and ecology. — Known only from the type material and an additional collection, near the
Araguaia River, as an understory shrub growing in sandy soil, in northern Tocantins.
Observations.—To my knowledge, Ixora araguaiensis is unique within the genus because of its bifid
Supe, as Ixora is SE EE by stipules with one arista. In several other species, older
k up irregularly into two units, but this is not the case in I. araguaiensis, because its stipules have
pe aristae (sometimes basally connate) since very early stage (Fig. 2B-C). However, the consistency of this
character within the species remains to be confirmed, as it is currently known from only two collections.
Conservation.—A rare species collected in the Parque Nacional do Araguaia, in the municipality of
Pium. Although it was collected inside a national park, this species should be included in the category with
imminent threat of extinction, due to the presence of large herds of cows grazing on the vegetation of this
park, especially during E season (May—September).
Etymology. —TI pithet of this taxon is dedicated to both the river and the national park where
it was pad
vations.—Thi ies is similar to Ixora brevifolia Benth. (Delprete 2003, 2007) because
of the terminal, corymbose to peda inflorescences, but differs by being a shrub ca. 1 m tall (vs. tree

INTRODUCTION
Amber is well known for its preservative qualities of both animal and plant remains (Poinar 1992, Poinar
& Poinar 1999). Amber flowers, maintained in three-dimensional form, are often preserved with such
detail that they can be assigned to extant genera (Spahr 1993). Such fossils can be useful in paleontological
reconstructions (Poinar & Poinar 1999).
The majority of described amber flowers originate from Baltic deposits (Spahr 1993); however legume
(Dilcher et al. 1992; Poinar 1991) and palm (Poinar 2002a, 2002b) flowers have been described from Do-
minican amber, and there are also descriptions of Early Cretaceous flowers in Burmese amber (Poinar &
Chambers 2005; Poinar et al. EE

MATERIALS AND METHODS
All 5 pieces of amber containing the fossil flowers originated from mines in the northern mountain range
(Cordillera Septentrional) of the Dominican Republic, between the cities of Puerto Plata and Santiago. Dating
of Dominican amber is controversial, with the youngest proposed age of 20-15 mya based on foraminitera
(Iturralde-Vincent & MacPhee 1996) and the oldest as 45-30 mya based on coccoliths (Cépek in Schlee
1999). Most of the amber is secondarily deposited in turbiditic sandstones of the Upper Eocene to Lower
Miocene Mamey Group (Draper et al. 1994).
The 6 flowers are similar in the morphology of their floral cup (hypanthium) and are assumed to have
originated from t] lant species. The amber piece containing the flower assigned to catalogue number
Sd-9-154A (Holotype) is el in outline, measures 13 mm in diameter, 9 mm in greatest thickness and
weighs 6 grams. The amber piece containing specimen Sd-9-154B is roughly triangular in shape, measures
12 mm along the sides, 7 mm at the base, is 3 mm thick and weighs 3 grams. The third amber piece (Sd-9-
154C) is rectangular, measures 8 mm by 7 mm along the sides, 2 mm in thickness and weighs 2 grams. The
fourth amber piece (Sd-9-154D), which contains the specimen with the petals, is semicircular in outline,
measures 17 mm in greatest length, 9 mm in greatest width, 7 mm in greatest thickness and weighs 1 gram.
The fifth amber piece (Sd-9-154E), which contains the specimen with the fruits, is trapezoidal in outline,
measures 17 mm in greatest length, 12 mm in greatest width, 8 mm in greatest thickness and weighs 1
gram. All specimens are deposited in the Poinar amber collection maintained at Oregon State University.

opposite the calyx lobes. The specimen in early flower (Sd-9-154D, Fig. 6) has all 5 petals visible, and one
is detached at the base, illustrative of what we term an early-deciduous corolla. The petals are clearly seen
when the specimen is viewed from the top as well as the sides. The center of this flower is unsuitable for
study due to an accumulation there of apparent insect remains and frass. The sharp hypanthial rim on the
3 flowers at or near anthesis shows where the petals presumably were attached, alternate with the sepals. It
remains ambiguous whether the sepal lobes were imbricate or valvate in the bud, perhaps because of ditfer-
ent degrees of spreading and separation in the samples at hand. Because no slits or pores are evident on the
back, sides, or tips of the anthers, we suggest an introrse dehiscence, which is supported by observations of
the adaxial side of one strongly inflexed stamen. The nature of the mature fruit is uncertain, although from
the shape and thick-textured exocarp of the 2 specimens here (Fig. 7), a non-compressed, l- or few-seeded
drupaceous fruit is suggested. Although atypical for members of the Fabaceae, several extant genera of the
Cassieae have similar indehiscent, drupaceous fruits. Dialium s.l. is characterized by small fruits consisting
of one seed surrounded by a soft, but somewhat dry, edible aril (Gentry 1993). Few-seeded, ovoid, fleshy-
or thick-walled fruits are not unusual in Fabaceae subfamily Caesalpinioideae (e.g. Lewis et al. 2005). This
fruit-type, together with a well- EES hypanthium, a superior simple pistil, regular corolla, reduced
stamen number, and a ium and pistil, are what lead us to suggest assigning the fossil
1 d
to this family anid ny
The caesalpinioid legumes are extremely diverse in floral characteristics, including numbers of stamens,
presence or absence of a hypanthium, numbers and form of petals, length of filaments, form of anthers and
stigmas, shape and structure of fruits, floral symmetry, modification to unisexuality, etc. The compendium
by Polhill and Raven (1981), with its taxonomic treatments of the relevant tribes (Cowan & Polhill 1981;
Irwin & Barneby 1981; Polhill & Vidal 1981), was E ina Sie for modern genera with the particular
combination of features seen in the fossils. Illust f genera were examined in Taubert
(1894), Hutchinson (1964), and Lewis et al. (2005). No examples have been found that correspond in all
respects with Lasiambix, but its described traits are present separately in numerous caesalpinioid genera.
A cup-shaped, externally puberulent hypanthium occurs frequently in the subfamily. Bilateral sym-
metry (zygomorphy) is also common, and this accompanies a reduction to three stamens in such genera as
Tamarindus, Macrolobium, Gilbert lron, Elizabetha, CES Dialium, etc. As discussed by Tucker (1998,
2002) there are parallel evolutionary trer dè | of stamen number in groups of related genera
in separate tribes (her examples were Detarieae-Amherstieae and Dialiinae). From the basic number 10,
stamens may be reduced to as few as 1 (some Dialium spp.), and during development, some of the stamen
primordia that form early may cease their growth and become rudimentary or staminodial (e.g. Gilbertio-
dendron, Macrolobium; Tucker 2002). Except for Dialium and Apuleia, the 3-stamen genera mentioned fall
into the Amherstieae (including Macrolobieae) clade, as defined by analysis of the chloroplast trnL intron
(Bruneau et al. 2001). This group is also recognizable in the rbcL analyses by Doyle et al. (1997) and Kajita
et al. 2001). However, the corolla evolution in these particular genera leading to loss of all but one petal
to form an adaxial vexillum (e.g. Cowan 1953) , the 2-many-seeded, mostly dehiscent pods, plus the usual
absence of a hypanthium, argue against a relationship to Lasiambix. Cynometra, also in this clade, is discussed
below.
Dialium and Apuleia, of subtribe Dialiinae, show some blance to Lasiambix in their zygomorphic,
few-stamened flowers and their few-seeded, indehiscent fruits. According to Irwin and Barneby (1981, p.
101) Dialium “can be defined accurately and rigorously by its pod, a sort of indehiscent, 1- or 2-seeded nut,
sometimes strongly, sometimes scarcely compressed laterally, consisting of a crustaceous exocarp and a
pulpy, when ripe mealy endocarp enveloping the seeds." In their key (p. 100) the fruit is termed “drupa-
ceous." The flowers of Dialium, a pantropical genus, are hypogynous and have only 1 or 2 petals and usually
2 stamens. The related Apuleia, of South America, possesses a hypanthium and 3 stamens, but its pistil is
exserted, not sessile, its perianth is 3-merous, and its pod is compressed and coriaceous, not ovoid. Despite
bix dominicensis, V—— E "S 469
= H d
Poinar et al., |
their few-seeded, indehiscent pods, neither of these few-stamen genera of Dialiinae suggests a close affinity
to Lasiambix.
Other possible relationships of the fossils are with genera having regular flowers and more numerous
stamens but with a similar type of few-seeded fleshy fruit. One such example is Vouacapoua of tribe Caesal-
pinieae (Lewis et al. 2005). This lar flowers with 10 short stamens, but its hypanthium,
sepals, and short petals much sale bio and its fruits are round, thick-walled, 1-seeded, and
dehisce by a single furrow (Lewis et al. 2005, p. 161; Polhill & Vidal 1981, p. 89). The genus is presumed to
have affinity to the Peltophorum group of tribe Caesalpinieae (Bruneau et al. 2001; Haston et al. 2003), but
as yet the DNA support for this connection is weak.
A similar type of fruit occurs in the large genus Cynometra of tribe Detarieae (Lewis et al. 2005, p.
89). Its pod is described as thick, turgid, rugose to verrucose (rarely smooth), 1-seeded, and regularly in-
dehiscent with a spongy pericarp (Hutchinson 1964, p. 235; Dwyer 1958); it lacks a floral disc, its ovary is
usually hairy, and its style may be eccentric in the hypanthium (Dwyer 1958, p. 322). However, it has 10
long-exserted stamens, a shorter hypanthium, and a usually showier perianth than in Lasiambix (Dwyer
1958). Other differences, besides these, are that its sepals are glabrous adaxially (except C. cubensis Rich.)
and its filaments are united very briefly at the base. Modern-day Arcoa, of Hispaniola, has turgid, 1-seeded,
indehiscent fruits (Lewis et al. 2005, p. 132), but its flowers differ considerably from Lasiambix in being
unisexual, bearing ca. 12 stamens, PA p an exserted pistil with capitate stigma (Herendeen et al.
2003). Another Caribbean genus, Stahli Caesalpinieae), has fleshy, 2-seeded, indehiscent fruits, regular
5-merous perianth, imbricate sepals, eg well-dev pel. dorsally puberulent petals (Hutchinson 1964, p.
235; Lewis et al, 2005, p. 145). It differs from Lasiambix principally in having 10 erect, connivent stamens
with filaments ely woolly in the lower half. Placement of Stahlia near the large genus Caesalpinia and its
segregates was established by the molecular and morphological studies of Simpson et al. (2003).
The examples mentioned, falling into several distinct clades within the subfamily, illustrate the paral-
lelisms in floral and fruit morphology that Ge it difficult to Mg a EE definitive placement of
Lasiambix. Alarge amount of recent phylog h, both 1 molecular, was reviewed
by Lavin et al. (2005), to estimate the time frame of early ven of this and other subfamilies of
Leguminosae. Earlier estimates of a Late Cretaceous origin of the family and a “basal” position for Caesal-
pinioideae (e.g. Polhill et al. 1981; Herendeen et al. 1992), are no longer accepted as “conventional wisdom.
Rather, the fossil record supports an origination in the Paleocene, allowing some 60 my for diversification
within the family (Lavin et al. 2005). In molecular phylogenetic studies, with best resolution provided by
the matK chloroplast gene, divergence of 6 early-formed lineages of caesalpinioids was found, along with
the similarly old crown nodes of many papilionoid and mimosoid clades. Caesalpinioids are viewed as a
paraphyletic grade from which stem the mimosoids and papilionoids, but because of the very early, rapid
branching of the ancestors of modern clades, the caesalpinioid grade “harbor(s) neither the oldest diversi-
fication nor some other quality of legume LÀ (Lavin et al. 2005).
If our suggested placement of Lasiambix is correct, it offers a well-preserved example of several special-
ized floral characteristics of Tertiary-age caesalpinioid legumes. These include the loss of all but 3 stamens
and accompanying bilateral symmetry of the flowers, an ins of peas at anthesis, and presence of few-
seeded, fleshy, probably indehiscent fruits. What polli ted by flowers with short,
incurved stamens and no apparent nectar disc, is difficult to m Perhaps Seia was produced at the base
of the ovary, which was not visible to us. In this case small bees might have been able to enter the flowers
and remove pollen from the arched, introrse anthers. The ecology of the plants is likewise unknown, other
than that they grew in proximity to Hymenaea in moist tropical forests such as those described by Poinar
and Poinar (1999). Such habitats are opes for many EE of modem: day Caesalpinioideae.
Note: In the illustrations, becau e orientation of | , we have not tried to suggest
a placement of the stamens as either abaxial, as in Macrolobium et al. (Cowan 1953) or adaxial as in Dialium
et al. (Tucker 1998).

In a recent paper (Phipps 2007) I inadvertently stated an incorrect collection date for the holotype of Cra-
taegus pisifera Sarg. It should be 28 September 1901 rather than 26 July 1901 as recorded in Phipps (2007).
The remainder of the commentary on C. ddp in ot Ge EE however.
With respect to the same paper pecialist at Harvard University,
Kanchi Gandhi, indicated " me hat I was in error in piis two lectotypes, as the names with which
I was dealing had never been validly published. Since 1 January 1958, in order to be validly published,
names must have a type indicated and a type must be a single specimen (see Vienna Code Art. 57.1, 8.1 and
8.2). However, the two names below were designated with a “type” representing specimens from different
gatherings. Thus, in order to validate Kruschke's names, holotypes rather than Tees i: have been
designated. Accordingly, the two names are validly published below with ap] ate
It may also be noted that were I to have ascribed the names to myself the Citations of the relevant names
would have been ‘J.B. Phipps’ but I retain ‘Kruschke, also permissible, therefore accepting Kruschke as the
author since he provided the validating Latin diagnoses (Art. 46.2)

RESUMEN
Thomas Walter, el autor de la Flora Caroliniana (1788), no dejó un herbario. Muchas de las especies que describió de las Carolinas y
Georgia no tienen tipo. Se seleccionan aquí especimenes que se su ponen representan 63 de las especies de Walter, para servir como
neotipos o epitipos.
This number of the Thomas Walter Typification Project is a continuation of a report begun previously
(Ward 2007c). Here, an additional 63 of Walter's species are addressed, with selection of appropriate
neotypes or epitypes.
Although the number of Walter neotypes, as treated in this and previous reports of the Project,
have been many, even now not all Walter names have been examined. No effort has been made to typify
most of the numerous Walter names that are now remembered only in synonymy. And those names not
represented by suitable materials in the herbarium of the present participating institution (GH) will be
addressed in a subsequent Dd
This report and its i iate predecessor (Ward 2007c) select types for 106 Walter names. Within
this number, 101 were selected as neotypes, and 5 as epitypes. The largest proportion, or 98, were of South
Carolina collections, 22 of them from Berkeley County; 4 were from Georgia, and 2 each from North
Carolina and Florida. A third, or 37, bore a total of 43 annotations confirming the label identifications.
The typifications are presented here in the format used previously (Ward 2007a, 2007b, 2007c), in
alphabetical sequence, using the names given them by Thomas Walter.

WALTER'S NAME: Galega spicata Walter (p. 188)
MODERN NAME: Tephrosia spicata (Walt.) Torr. & A. Gray
Common throughout. Spm. 49-B may be the specimen referred to by Wood (1949: 292) as the type of
Galega spicata (^GH - photograph of Type in Herb. Walt."). But since Wood cited only the herbarium,
not a specific specimen, leaving uncertainty which specimen was intended, unambiguous typification
is justified. Godfrey & Tryon 1310, 7 Aug 1939 - GH, from 14 mi S of Columbia, Lexington County, South

WALTER's NAME: Hibiscus coccineus Walter (p. 177)
MODERN NAME: Hibiscus coccineus Walt.
Not presently known in NC, SC, or GA (reported from GA by Small 1933), apparently unknown n. of Duval
Co., FL. An old (undated) specimen has been seen from Charleston, SC (GH), perhaps from cultivation.
Spm. 58-E is clearly this; it bears Fraser's number “674” (an indication of mid-season collection, thus it
could not have been obtained on Fraser's spring trip into southern Georgia). It was labeled "Hibiscus" by
Walter, with “Coccineus” added by Fraser. Though spm. 58-E could be claimed a lectotype, the possibil-
ity that Walter may have had seen it near Charleston, his market town, and his failure to note Fraser's
specimen as a species of his own making, makes that status unlikely. Blanchard 173, 14 Jul 1968 - GH,

Florida, is here selected as NEOTYPE of Hibiscus coccineus Walt. Known ISONEOTYPES: CAS.
WALTER' NAME: Hydrastis caroliniensis Walter (p. 156)
MODERN NAME: Trautvetteria caroliniensis (Walt.) Vail
Nearly absent from SC, but common in western NC; probably a Fraser discovery. Spm. 1-E is of poor
quality, and was mislabeled “Actea racemosa?” by Walter. Although Walter may have known this species
only by way of Fraser's collections, his failure to recognize spm. 1-E as a species he himself had named
makes unlikely his having used it in his writing. Thus, rather than designating spm. 1-E as lectotype,

WALTER'S NAME: Hypericum petiolatum (p. 191)
MODERN NAME: Triadenum walteri (Gmel.) Gleason [= Hypericum walteri Gmel.; 2 Triadenum petiolatum

Frequent throughout. Not Hypericum petiolatum L.; Walter's Hypericum petiolatum was a later homonym
(1763 vs. 1788) and thus illegitimate. But Gmelin's replacement (1791) was based on Walter's name and
description. No specimen has been identified. Duncan hie 20 SC nari GH, from 4.2 mi E of Lafay-

WALTER'S NAME: Ischaemum secundatum Walter (p. 249)
MODERN NAME: Stenotaphrum secundatum (Walt.) Kuntze
Infrequent in eastern SC. Identified by Hitchcock (1905: 55) from Walter's description. There is no
specimen. The species in the Southeast consists of two variants (“demes”), one native, one introduced
(Sauer 1972). Ahles 15602, 27 Jun 1956 - GH (annot. J.D. Sauer 1971), from roadbank, U.S. 21, Beaufort,

MODERN NAME: Kalmia hirsuta Walt.
Rare in SC (5 counties). Spm. 62b-C, a nearly bare twig, was labeled “Kalmia Hirsuta Nova” by Fraser.
Southall & Hardin (1974) referred to a specimen on page 62 as the "type." Their typification has been
corrected (Ward 20072) to lectotype. The specimen, however, is unidentifiable without the label and
serves no useful purpose as a type. Bell 3956, 29 Jun 1956 - GH (annot. J.E. Ebinger 1972), from S.C. 631,

Very rare in SC (3 counties, but one is Charleston, Walter's market town). No specimen appears to be
this species. But Peng et al. (2005: 345) cited spm. 66-D as “holotype” of Ludwigia arcuata, apparently in
gross error! (The cited specimen appears to be L. pilosa, and was so labeled by Walter.) With the expec-
tation that the error will be acknowledged and effort undertaken to correct the erroneous typification
via conservation, Radford 11411, 8 Sep 1967 - GH, from Millettville, Allendale County, South Carolina,

WALTER'S NAME: Lycium carolinianum Walter (p. 84)
MODERN NAME: Lycium carolinianum Walt.
There is no specimen. A coastal plant, at times reported for SC, but only on the basis of Walter's listing,
and a note in Elliott. Presently unknown in SC; almost unknown in GA (Camden Co., the southeastern
corner). Undoubtedly a discovery of Fraser's, but it is difficult to understand how he could have journeyed
that far south. Perhaps since his time the range of this cold-sensitive plant has contracted southward.
This possibility is supported by Elliott (1816: 1: 200): “I have never seen this plant in its native state,
where it is said to be of very humble growth. Found by Mr. Wm. Bartram, in the sali hy marshes of
Carolina.” Curtiss 6543, 10 Oct 1899 - GH (annot. C.L. EES E. from mouth of St. Johns River,

northern species that reaches NC (two counties) but is unknown in SC. Walter did not include H. bullata
in his Flora. Though he SHOE AIME muscaetoxicum, which he included as “Melanthium Muscaetoxicum,"

Common in eastern SC. Pennell (1920: 243) stated: “Description sufficiently distinctive.” Pennell (1946)
again recognized Walter's description as this species and used this name, but designated no type. No
corresponding specimen is apparent. Godfrey & Tryon 948, 26 Jul 1939 - GH (annot. H.S. Wooden 1979),

WALTER' NAME: Pinus glabra Walter (p. 237)
MODERN NAME: Pinus glabra Walt.
Frequent in southeastern SC. Dayton (1952) and Ward (1962) confirmed Walter's description; Dayton
identified spms. 83-D and 83-H as this species. Dayton proposed that these two specimens “perhaps
should be considered the type material" of Pinus glabra, but made no designation. Though spm. 83-H
was labeled “Pinus” by Walter (and spm. 83-H by Fraser), there is no evidence Walter used it in forming
his description. Palmer 35395, 16 May 1929 - GH, from Seneca, Oconee County, South Carolina, is here

spms. 83-I (labeled “Pinus” by Walter) and 83-J (unlabeled) as this species. Dayton (1952: 71) suggested,
“it is possible that this [spm. 83-I] may be the type of Walter's P. squarrosa.” However he stopped short
of designating the specimen as type. A better specimen, with cones, Godfrey & Tryon 1453, 10 Aug 1939

Common in eastern SC. Smith & Ward (1976) referred to a “holotype,” but noted “not seen and presum-
ably no longer extant." Spm. 84-B, labeled "Polygala" by Fraser, has since been identified as P. cymosa. It
is of poor quality, consisting solely of an upper inflorescence. In the absence of evidence that spm. 84-B
was seen or used by Walter, Godfrey & Tryon 67, 24 Jun 1939 - GH (annot. Foard 1959), from 15 mi N of

WALTER'S NAME: Quercus pumila Walter (p. 234)
MODERN NAME: Quercus pumila Walt. [= Quercus elliottii Wilbur]
Common in eastern SC. Spm. 90-E is poor, and though it was seen (and labeled, as “Quercus pumila”) by
Walter, there is no suggestion that it was used by him. Godfrey & Tryon 1420, 11 Aug 1939 - GH, from 8
mi S of Moncks Corner, Berkeley County, South Carolina, is here selected as NEOTYPE for Quercus pumila
Walt. Known 1isoNEOTYPEs: NY, US. Wilbur (2002: 138-140) has argued that Walter's description was de-
fective, and that the small shrub should be renamed Quercus elliottii Wilbur. In light of the near-certainty
that Walter knew his Quercus pumila (as seen within stone-throw of his grave - D.B.W. obs., Jun 1990),
the new name is superfluous.
WALTER's NAME: Rhexia petiolata Walter (p. 130)

BM, marked “Rhexia 723” as “type” of Rhexia petiolata Walt. (The “Rhexia” is in Walter's hand, the “723” in
Fraser's.) James' typification has been corrected (Ward 20072) to neotype for Rhexia petiolata Walt. James
noted, "Positive identification has not been possible because of pu dris condition of the speci-

MODERN NAME: Silene caroliniana Walt.
Frequent throughout SC. Spm. 98-G was labeled “Silene an virginica?” by Walter. Wilbur (1970) referred to
comments of J.K. Small and C.A. Weatherby—neither of who personally saw the Walter herbarium—to
conclude the specimen was unclear as to its subspecies, and that ^Walter's description is unmistakable
and would take precedence over any specimen in the Walter herbarium.” Thus Weatherby 6114, 27 Apr

Common in southeastern SC. Spm. 101-A, a reasonably lete intl el the label “Staehelina”

need not have used this specimen in forming his description. Boufford & Shi 30292, 25 Sep 2000 - GH,

WALTER'S NAME: Syntherisma serotina Walter (p. 76)
MODERN NAME: Digitaria serotina (Walt.) Michx.
Hitchcock (1905: 44) found Walter's di ting this and the
made the identification on the basis of hese being the only creeping Digitaria “found commonly” in the
Carolinas. But, far from common, D. serotina is very rare in SC (2 counties), suggesting Walter's second
species may also have been the abundant and somewhat variable D. sanguinalis. There is no specimen.

Frequent throughout. Hitchcock (1905: 44) accepted spm. 116-C as corresponding to Walter's diagnosis.
The specimen is labeled in Walter's hand. But it is poor and unlikely to have been used by Walter in
forming his description. Andersen 1408, 1897 - GH (annot. M.L. Fernald 1920), from Oconee County,
South Carolina, is here selected as NEOTYPE for Syntherisma villosa Walt., basionym of Digitaria villosa
(Walt.) Pers.
WALTER'S NAME: Utricularia purpurea Walter (p. 64)
MODERN NAME: Utricularia purpurea Walt.
Infrequent on the SC coastal plain. There is no specimen. Taylor (1989: 689) stated: "lecto. Barnhart
1916;” but Barnhart's action (1916: 62) was a typification of the segregate genus Vesiculina Raf., not a
typification of the species U. purpurea. Godfrey & Tryon 1097, 4 Aug 1939 - GH, from 6 mi NW of McClel-
lanville, Charleston, South Carolina, is here selected as NEOTYPE for Utricularia purpurea Walt. Known
ISONEOTYPES: BH, CA, CAS, DUKE, F, MO, US.
WALTER'S NAME: Viburnum obovatum Walter (p. 116)
MODERN NAME: Viburnum obovatum Walt.
Frequent in eastern SC. The only possible specimen (spm. 108-H) is a fragment, bearing only Fraser's
label, “Viburnum.” Godfrey & Tryon 8215, 24 Jul 1939 - GH (annot. Thomas H. Jones 1978), from 10 mi NE
of Moncks Corner, Berkeley County, South Carolina, is here selected as NEOTYPE for Viburnum obovatum
Walt. Known ISONEOTYPES: CA, CAS, DUKE, F, MO, NY, PH, US.
WALTER' NAME: Vicia caroliniana Walter (p. 182)
MODERN NAME: Vicia caroliniana Walt.
Frequent in eastern SC, more westward. Spm. 106-D appears to be thi ies. But since Walter
labeled it only as “Vicia nova,” it is A it was used in preparing his desceiotiom. Hunnewell 8163, 23
Mar 1922 - GH (annot. Robert Dirig 1990), from Goose Creek, Berkeley County, South Carolina, is here
selected as NEOTYPE for Vicia caroliniana Walt.

WALTER'S NAME: Vincetoxicum gonocarpos Walter (p. 104)
MODERN NAME: Matelea gonocarpa (Walt.) Shinners
Infrequent in SC, nearly absent from the coastal plain. Thus likely a Fraser discovery. Spm. 109-A,
marked “Vincetoxicum” by Walter, was identified as Matelea gonocarpa by Drapalik (1970: 76, from photo).
But it is sterile, which makes it unlikely to have been of use to Walter, who described the plant in detail
(incl. flowers and fruits). A specimen of better quality, Wiegand & Manning 2629, 16 Jul 1927 - GH (annot.
Donald J. Drapalik 1974), from Meggett, Charleston County, South Carolina, is here selected as NEOTYPE
for Vincetoxicum gonocarpos Walt., basionym of Matelea gonocarpa (Walt.) Shinners.
WALTER'S NAME: Viola canina sensu Walter (p. 219) non Viola canina Linnaeus, Sp. Pl. 935. 1753; misap-
plied.
MODERN NAME: Viola walteri House
Infrequent throughout. Not Viola canina L., nor V. conspersa Rchb. When House (1906) realized Walter
had EE the Carolina plant he assigned it a new name, V. walteri, but based the new name on
Walter's di 1 presumed type. There is no specimen. Hunnewell 12638, 30 Mar 1933 - GH (annot.
Harvey E. Ballard 1991), from near Goose Creek, Berkeley County, South Carolina, is here selected as
NEOTYPE for Viola canina sensu Walter (basis for Viola walteri House).
WALTER'S NAME: Viola villosa Walter (p. 219)
MODERN NAME: Viola villosa Walt.
Frequent throughout. Spms. 108-D and 108-1 may be this species. Both bear Walter's hand, but only to
“Viola” and a descriptive phrase; both are of poor quality. Brainerd (1907) has argued convincingly that
Walter's plant was this species (and not V. hirsutula Brainerd, found only inland). Brainerd s.n., 25 Mar
1907 - GH (annot. Landon E. McKinney 1986), from Summerville, Dorchester County, South Carolina,
is here selected as NEOTYPE for Viola villosa Walt.
WALTER'S NAME: Waltheria caroliniana Walter (p. 175)
MODERN NAME: Piriqueta caroliniana (Walt.) Urban
Frequent in southeastern SC. No specimen has been identified. Ahles 18262, 9 Sep 1956 - GH, from SC
20, 2.7 mi S of jct. with SC 39, Hampton County, South Carolina, is h elected for Waltheria
caroliniana Walt., basionym of Piriqueta caroliniana (Walt.) Urban. Known isoNEorTYPEs: NCU.

Thevetia L. belongs to the A bfamily R lfioideae tribe Pl nd ight species
of shrubs occurring from Central Mexico to porten South America (Gensel 1969; williams 1996; Allorge
1998; Endress et al. 2007). According to various specialists in the Apocynaceae, the generic boundaries of
Thevetia vary. In the concept of Thevetia sensu K. Schum. (Schumann 1895; Gensel 1969; Williams 1996;
Allorge 1998; Alvarado-Cardenas 2004), eight species are sub-divided between two sections: sect. Ahouai
K. Schum. with three species—T. ahouai (L.) A. DC., T. amazonica Ducke, and T. bicornuta Mull. Arg.—and
sect. Thevetia K. Schum. with five species—T. gaumeri Hemsl., T. ovata (Cav.) A. DC., T. peruviana (Pers.) K.
Schum., T. pinifolia (Standl. & Steyerm.) J.K. Williams, and T. thevetiodes (H.B.K.) K. Schum. In the concept
of Thevetia sensu Lippold (Lippold 1980; Alvarado-Cardenas & Ochoterena 2007) the three species of
sect. Ahouai are retained in Thevetia; the other five species of sect. Thevetia are segregated into the genus
Cascablea Raf. Although Lippold (1980) and Alvarado-Cardenas and Ochoterena (2007) segregate Thevetia
sensu K. Schum. into the two genera Thevetia and Cascablea, at no point do they argue against the genera's
“close morphological relationship" (Alvarado-Cardenas & Ochoterena 2007). In fact, a recent morphological
cladistic analysis (Fig. 1, Alvarado-Cardenas & Ochoterena 2007) nests all eight species of Thevetia sensu K.
Schum. in a clade supported by six synapomorphies. In short, Thevetia sensu K. Schum. is clearly shown to be
monophyletic. Nevertheless, Alvarado-Cardenas and Ochoterena (2007) argue for its paraphyly and choose
instead to recognize the two sub-clades of the clade (Fig. 1) as distinct genera: Thevetia and Cascabela.
Chromosome numbers have proven useful in resolving generic relationships in the Ay (Van
der Laan A Pid Wiens 2007): bs date, 73 of the 179 genera of the Apocynaceae s. sit (subfamilies

MATERIALS AND METHODS
Roots tips and voucher specimens were collected from a greenhouse specimen of Thevetia ahouai housed
at the greenhouse of the Department of Biological Sciences, Sam Houston State University (Table 1). The
root tips were fixed and analyzed for chromosome number using standard procedures (Raffauf 1964; Van
der Laan & Arends 1985). A voucher specimen of the greenhouse plant was made and is preserved in the
Warner Herbarium (SHST).
RESULTS
The format used for reporting chromosome numbers in this article follows that established by Strother and
Nesom (1997). A mitotic chromosome number of 2n = 20 was recorded for Thevetia ahouai. Van der Laan
and Arends (1985) reported chromosome lengths in the Apocynaceae to be between 0.5-4.0 pm, with the
average chromosome length between 1-2 pm. The length of the chromosomes in T. ahouai varied between
13 um, consistent with most other chromosomes in the Apocynaceae. The base chromosome number (x -
10) for Thevetia ahouai is consistent with previous reports of x = 10 for Thevetia (T. peruviana 2n = 20; Gadella
1977; Ugborogho 1983; Van der Laan & Arends 1985; Santhosh & Omanakumari 1997).
DISCUSSION
Van der Laan and Arends (1985) postulated a base chromosome number of x = 11 for the Apocynaceae s.
str. based on its prevalence in the family and on the observation that many of the plesiomorphic taxa pos-
sess a base number of x = 11. A base chromosome number of x = 10 is found in four genera representing
three of the 11 tribes recognized in the Rauvolfioideae (Endress et al. 2007): Hunterieae (Gonioma E. Mey.),
Plumerieae (Cerbera L., Thevetia), and Vinceae (Ochrosia Juss.). Based on tribal circumscription (Endress
et al. 2007) along with molecular evidence (Simóes et al. 2007), x= 10 is reconstructed as having evolved
independently at least three times in the Rauvolfioideae.
A cursory review of chromosome counts for the Apocynaceae (Van der Laan & Arends 1985; Goldblatt
& Johnson 2003) reveals that at present the only chromosome ts for genera in the Plumerieae, and thus
relatives to Thevetia (2n = 20), are for Allamanda L. (n = 9; 2n - 18), Cerbera (2n = 40), Himatanthus Willd. ex
Schult. (2n = 18), Mortoniella Woodson (2n = 32), and Plumeria L. (2n = 36). At present there are no chromo-
some counts for the remaining four genera in the Plumerieae: Anechites Griseb., Cameraria L., Cerberiopsis
Vieill. ex Pancher & Sébert, and Skytanthus Meyen., and it is suggested here that effort be made to ou
count of these taxa. Figures 1 and 2 present cladograms of the Plumerieae constructed from
(Alvarado-Cardenas & Ochoterena 2007) and molecular evidence (Simóes et al. 2007), respectively Dipleld
counts for the respective genera included in the phylogenies are presented for both Figures 1 and 2.
Alvarado-Cardenas and Ochoterena (2007) presented six synapomorphies that described the Thevetia
sensu K. Schum. clade (Fig. 1, branch a). The diploid count of 2n = 20 presented here adds a seventh syna-
pomorphy. When interpreting their data Alvarado-Cardenas and Ochoterena (2007) state that “(here is
still no consensus regarding the question of whether one should recognize one genus with two (sections)
or two distinct genera (Lippold 1980), given that Cascabela and Thevetia are sister taxa." We would argue
that the consensus in evolutionary systematics is to assign generic boundaries that reflect both monophyly
and shared ancestry. The decision to divide a well supported clade into two separate genera may support
monophyly; however, it excludes shared ancestry. Without prior knowledge most botanists Wong be un-
aware that Thevetia and Cascabela ister taxa that sl Instead, an il
more meaningful interpretation of the clade would be that Thevetia: sensu K. Schum. is monophyletic aad
support is provided for the recognition of two sections as defined by Schumann (1895). In order to maintain
systematic consistency as pertains to current trends in phylogenetic nomenclature we recognize Thevetia
sensu K, Schum. and regard Cascabela and all taxa pertaining to the genus as synonyms of Thevetia.

INTRODUCCIÓN
El Eje Volcánico Transversal es un sistema montañoso que cruza transversalmente México, en su mayor
parte entre los paralelos 19? y 20? N. Esta área se sitúa a lo largo de unos 950 km desde la región del Volcán
Ceboruco al poniente hasta el Pico de Orizaba al Oriente (Rzedowski 1978). En México, el Eje Volcánico
Transversal incluye las prominencias topográficas de mayor altitud que, en sus partes altas albergan man-
chones de vegetación alpina y subalpina y el área total ocupada por esta vegetación es reducida y está sujeta
a cambios ecológicos.
Entre 3500 y 4500 m de altitud se observan comunidades de gramíneas amacolladas, denominadas
pastizales o zacatonales alpinos y subalpinos. Los pastizales alpinos se localizan por encima del límite de
" vegetación Gd El límite superior de este pastizal se sitúa SIE ODE de did m de SE ER

son los más frágiles dada la corta duración de la estación de crecimiento y la lentitud de los procesos de
regeneración que siguen a la perturbación (McDonald 1998).
Los pastizales alpino y subalpino, en forma natural, están condicionados por ciertos factores como
temperaturas bajas, disponibilidad de agua, intensidad y duración de luz solar y nutrientes, entre otros. De
manera artificial, están condicionados por la tala inmoderada y los incendios, estos últimos usados para
provocar el brote de retoños que sirven de alimento para el ganado. La vegetación alpina-subalpina del Eje
Volcánico Transversal es única en su tipo y de alto interés biológico, muestra una composición florística
notoriamente distinta a la de otras regiones alpinas del país (McDonald 1998) y, es de esperarse que, las
especies de estos Ge posean EE anatómicos distintivos y propios de su hábitat.
Los estudios en pocos y en su mayoría han tenido, principalmente,
un enfoque — donde n anatomía se EE parcialmente. Así, se han abordado revisiones
taxonómicas y descripciones de nuevas especies de los géneros Festuca L., Sporobolus R. Br., Triniochloa
Hitchc., Trisetum Pers., Muhlenbergia Schreb., entre otros (González-Ledesma 1991; González y Koch 1994;
González-Ledesma et al. 1995, 1998; Hernández y Engleman 1995; Peterson y Herrera-Arrieta 2001; Reyes
2004; Cruz Díaz 2005). Algunos estudios que detallan la anatomía foliar han permitido separar géneros
(Valdés-Reyna y Hatch 1995) como Erioneuron Nash y Dasyochloa Willd. ex Rydb., establecer grupos y sub-
grupos de las especies | de Eragrostis Wolf (Gómez-Sánchez y Koch 1998), proponer la separación
de Swallenia alexandrae (Swallen) Soderstr. & H.F. Decker de la subtribu Monanthochloinae Pilg. ex Potzal
(Gómez-Sánchez et al. 2001), delimitar algunas especies de Trisetum (Hernández y Engleman 1995) y de
Muhlenbergia (Peterson y Herrera-Arrieta 2001), entre otros.
Este estudio describe y analiza la anatomía de la lámina foliar de algunas gramíneas que habitan en
nas alpinas y subalpinas provenientes de los principales picos montañosos del Eje Volcánico Transversal,
en México. Asimismo, los patrones de los gradientes ecológico y geográfico se comparan con las caracterís-
ticas anatómicofoliares de los diferentes taxa.
MATERIALES Y MÉTODOS
Muestras de especímenes de 21 especies se obtuvieron de los Herbarios CHAPA, ENCB, IEB y QMEX,
acrónimos según Holmgren et al. (1990). De cada especie, se estudiaron 1-16 especímenes según la di-
sponibilidad de material. Hojas basales maduras se rehidrataron con agua caliente durante 1-5 minutos.
De la parte media de la lámina foliar se hicieron cortes transversales a mano libre con navaja de afeitar para
observar la estructura interna. 1 con hipoclorito de sodio al 6% (cloro de uso doméstico)
para aclarar y suavizar los tejidos y posteriormente se lavaron con agua corriente. La epidermis abaxial se
aisló mediante la técnica de raspado directo y las muestras | tes se montaron con jalea glicerinada,
sin tinción (Gómez-Sánchez y Koch 1998). La epidermis adaxial no se aisló debido a la presencia de surcos
fuertemente BEE
P lecc ] ión directa al microscopio para definir
y
diferencias anatómicas entre especies. Mediante encon se hizo una comparación de los patrones
anatómicos entre especies y éstos se compararon con el hábitat. La anatomía foliar se definió con la termi-
nología y descripción de acuerdo a Ellis (1976, 1979) con algunas modificaciones según Gómez-Sánchez y
Koch (1998). Las figuras de la anatomía foliar de las especies se elaboraron con ayuda de un microproyector
o por observación directa al microscopio. En el caso de la epidermis, están orientadas de tal manera que el
eje longitudinal de la lámina foliar aparece en posición horizontal en la ilustración y el ápice de la lámina
se ubica a la derecha.
RESULTADOS Y DISCUSIÓN
La anatomía foliar se estudió en 21 especies de gramíneas, seleccionadas por su presencia destacada en los
principales picos montañosos del Eje Volcánico Transversal, de las cuales 13 son alpinas y ocho subalpinas
(Cuadro 1). La lámina foliar mostró 17 caracteres diferenciales en la estructura interna y nueve en la epidermis

abaxial. Con base en la anatomía foliar se identificaron los tipos anatómicos Pooide y Cloridoide. Las es-
pecies se arreglaron en dos grupos: Alpino y Subalpino. En el grupo Alpino se identificaron los dos tipos
anatómicos, que corresponden a las rutas metabólicas C, y C,. El grupo Subalpino posee especies con tipo
aatómico Pooide y metabolismo C, (Brown 1958; Ellis 1977).
Las plantas C, tienen anatomía no-Kranz y las plantas C, tienen anatomía Kranz o de corona (Brown
1977; ME éd ” especies no-Kranz (C,) fijan el CO, DEE mediante la enzima ribulosa 1,5-di-
fosfato carboxilasa el primer producto es el ácido 3- so esco (3-PGA), proceso que sucede en las células

1977). Las especies Kranz (C,) fijan el CO,, durante las horas de luz, en las células del neo mediante
la enzima fosfoenolpiruvato carboxilasa y el primer producto de la fotosíntesis es el ácido oxalacético , ácido
málico o ácido aspártico. Estos productos son transferidos a las células de la vaina Kranz donde sucede la
descarboxilación y luego la fijación (Brown 1975 y 1977; Ellis 1977; Hattersley y Watson 1976). La anatomía
de estas plantas se distingue por posset una o o vainas dee MSN muestran una vaina parenquimatosa
(Kranz) alrededor de los haces as del mesófilo. Esta vaina

1977; Johnson y Brown 1973) y con frecuencia es Biens por columnas de células incoloras.
Anatomía foliar de Gramíneas Alpinas.—La mayoría de las especies alpinas habitan principalmente
por encima de 3500—4500 m de altitud, aunque llegan a crecer en zonas boscosas y en niveles altitudinales
inferiores. Estas plantas son herbáceas, perennes, rizomatosas, desarrollan macollas robustas y fuertes y
alcanzan de 30—70 cm de altura. Su presencia es notoria en claros de bosques de Pinus, en lugares pertur-
bados, a a orilla E caminos y en pce pie ee grupo de e po ae anatómicos en Se

eon la insolación es alta, la disponibilidad de agua es baja, las sequías y temperaturas son extremas, oca-
y heladas y los vientos son fuertes. En estas zonas, al igual que en las áreas secas o desérticas,
ocurre el fenómeno llamado “verano de día, invierno de noche”, ya que durante las horas de insolación se
alcanzan temperaturas bastante altas y, al llegar la noche, la temperatura desciende tanto que generalmente
el suelo se congela y las plantas no pueden disponer de agua. Esto permite que las plantas muestren rasgos
morfológicos que también son propios de aquellas que crecen en ambientes secos y desérticos (Smith y
Young 1987). En las zonas subalpinas es común encontrar representantes arbóreos de los géneros Juniperus,
Pinus y Abies (Starker 1950) por lo que en estas áreas los vientos no son tan fuertes. A mayor altitud, más
desarrollados son los rasgos anatómicos que proporcionan protección contra la evapotranspiración, los da-
Dos mecánicos y la insolación, tales como los estomas protegidos, desarrollo de aguijones grandes, micro y
macropelos, desarrollo conspicuo de fibras y di tas en trabas y células buliformes en abanico y grandes
que intervienen en la involución de la lámina, entre otras.
Las especies alpinas exhiben un patrón anatómico distintivo. La lámina
y ganchos numerosos, las púas son largas y de base ancha sobre el margen, el esclerénquima está dispuesto
en trabas o en hebras de tres células de ancho y 6-8 células de alto, el clorénquima es reducido y las células
buliformes son grandes que se disponen en formas diversas, y las células incoloras son conspicuas. Las es-
pecies alpinas son de fisiología C,, excepto las tres especies de Muhlenbergia que son C,. Este metabolismo
les confiere rasgos anatómicos adicionales que les aseguran su desarrollo en estas zonas.
Epidermis abaxial.—Los caracteres anatómicos diferenciales de las especies alpinas se muestran en
el Cuadro 2. Todas las especies alpinas desarrollan ganchos en las regiones costal e intercostal y son de
tamaño mediano y base ancha (Figs. 1 y 2). Púas más grandes (Figs. 2, 3 y 4) y de base más ancha que los
estomas y se desarrollan sobre el margen. Esta presencia de aguijones (ganchos o púas) refleja la continua
condición de sequía a la que las especies están expuestas (Ellis 1979; González-Ledesma et al. 1995; Gómez-
Sánchez et al. 2001; Mejía-Saulés y Gómez-Sánchez 2001) y, a mayor estrés hídrico, mayor es la cantidad
y el tamaño de los aguijones y el grosor de sus paredes. El estrés hídrico es habitual en las zonas alpinas,
pues la disponibilidad de agua se reduce por la congelación y la alta evaporación producida por la intensa
radiación solar. Así entonces, la presencia de aguijones, en las especies alpinas, proporciona un mecanismo
de protección contra el daño provocado por la insolación proyectando sombra sobre la lámina y reduciendo
el calentamiento y la excesiva pérdida de agua. A mayor tamaño y frecuencia de los aguijones, mayor es la
sombra que proyectan y se reduce la exposición a la sequía a la que estas especies están expuestas. En Poa
orizabensis Hitchc. (Fig. 4), Triniochloa stipoides (Kunth) Hitchc. (Fig. 13), Calamagrostis orizabae (Rupr. ex
E. Fourn.) Beal (Fig. 10), Calamagrostis tolucensis (Kunth) Trin. ex Steud. (Figs. 2 y 21), Muhlenbergia nigra
Hitchc. (Fig. 6) y Muhlenbergia quadridentata (Kunth) Trin. (Fig. 8) los aguijones son más abundantes y de
mayor tamaño que en el resto de las especies alpinas. Esto explica que dichas especies predominen en los
zacatonales alpinos (Rzedowski 1978) y se desarrollan en los hábitats de mayor altitud. Triniochloa stipoides
(Fig. 13) es la única especie con pelos en su epidermis. Estos resultados sugieren que en el resto de las
especies alpinas los micropelos y los macropelos no son necesarios ó bien son remplazados por aguijones.
Las especies alpinas muestran en la epidermis abaxial, una cutícula más gruesa que aquella que se
observa en el grupo subalpino, sin embargo, en ambos grupos esa cutícula contribuye a regular la pérdida

de agua por evapotranspiración.
Los estomas, en algunas especies, no son visibles (Figs. 2, 5, 8-12) probablemente porque están trasla-
pados y ocultos por los EES une SE y Koch te EE están embebidos en el mesófilo
(Salisbury y Rose 1994) y f liminado tra, o bien, porque los estomas
están confinados a los surcos adaxiales de la lámina (mes Sánchez et al. 2001). En cualquiera de estos
microambientes la temperatura es menor y los estomas están protegidos, por lo que también se reduce la
pérdida de agua por transpiración.
Los cuerpos de sílice son numerosos y más abundantes en las especies alpinas que en las subalpinas y
toman formas de hígado (Fig. 5), de pesa (Fig. 8), son redondos (Fig. 6), cuadrados (Fig.1), altos y estrechos

Estructura interna.— Los iferenciales de la estructura interna que distinguen
a las especies alpinas se muestran en el Cuadro 3. El quina es copioso y forma hebras (Fig. 22) o
trabas (Figs. 14, 16, 23 y 25) orientadas adaxial o abaxialmente como una extensión de la vaina de los haces
vasculares. Algunas veces, el esclerénquima se desarrolla en bandas (Fig. 18 y 26) que recorren la anchura
de la lámina. Su presencia sugiere una baja disponibilidad de agua, que es un elemento importante de sos-
tén, y que evita la apertura total de la lámina impidiendo que ésta tenga una prolongada exposición a la luz

Deschampsia liebmanniana (E. Fourn.) Hitchc. (Fig. 22) y Festuca hephaestophila Nees ex Steud. (Fig. 24).
Esta quilla proporciona sostén y está asociada al control de la pérdida de agua por lo que sugiere que estas

Las células buliformes se restringen a los surcos adaxiales, son conspicuas, en forma de abanico (Figs.
14, 16, 23) o son redondas (Figs. 18, 22 y 24). Las trece especies alpinas, estudiadas aquí, muestran células
buliformes. Estas células responden a cambios de turgencia provocando la involución de la lámina, mecan-
ismo que regula el paso de luz hacia el mesófilo y la evapotranspiración (Ellis 1979). Estas células no sólo
intervienen en la apertura y cierre de la lámina, sino también en s absorción y retención de agua (Tschirch
1882, citado ud Els Vind Así entonces, cuando las células buliformes disminuyen su turgencia provocan
enlaláminau gr itando así que la lámina tenga una iva exposición a la luz solar
(Ellis 1976, Gómez-Sánchez y Koch 1998). De esta manera, las especies alpinas son beneficiadas porque las
células buliformes permiten la involución de la lámina y absorben y retienen agua favoreciendo su super-
vivencia en los zacatonales alpinos, mismos que están expuestos a una intensa y prolongada insolación y a
sequías extremas.

asociadas a las buliformes, funcionan como canales facilitando y regulando el See de luz hasta las células
de clorénquima (Ellis 1976) o las de la vaina Kranz. Esta regulación, además de incidir en un metabolismo
eficiente, evita alteraciones al material genético de los cloroplastos, mismas que pudieran ser provocadas
si la lámina tuviése una prolongada exposición a los rayos ultravioleta (Ellis 1976; Salisbury y Ross 1994;
Gómez-Sánchez y Koch 1998).
Las tres especies de Muhlenbergia (Figs. 25 y 26) estudiadas aquí, manifiestan una anatomía Kranz
y metabolismo C,. Estas Mee muestran el mesófilo reducido, regularmente dispuesto alrededor de los
haces vasculares, estos últimos, están protegidos por una vaina a manera de corona (vaina del haz) de células

hojas más estrechas y delgadas que las subalpinas. Esto sugiere que hay una relación estrecha entre la
anchura y el grosor de la lámina y la exposición continua a ambientes secos, aspecto que coincide con Red-
man (1985, citado por Gómez-Sánchez y Koch 1998) quién determinó que la anchura y el grosor de la hoja
están asociados a la resistencia a sequía.
Bromus anomalus y B. exaltatus (Figs. 14 y 20), como las demás especies alpinas, desarrollan un es-
clerénquima copioso que forma trabas abajo y arriba de los haces vasculares, tienen láminas estrechas,

margen, los ganchos son cortos y de base angosta ó están ausentes en Agrostis bourgeaei E. Fourn. y Phleum

observan pequeñas trabas de 2 a 4 células de ancho "n de los Gees Keser SE el clorénquima
es abundante con arreglo irregular y las células buliformes están son pequeñas,
a veces son redondas. Todas las especies subalpinas, aquí "v carecen de "m incoloras y de la
corona Kranz manifestando una anatomía no-Kranz y metabolismo C,.
Epidermis abaxial.—Los rasgos anatómicos observados en la epidermis abaxial de las especies sub-
alpinas se describen en el Cuadro 4. El grupo de especies subalpinas, tratadas aquí, contrasta fuertemente
con el grupo alpino en la mayoría de sus rasgos anatómicos. En la epidermis de estas especies subalpinas
los ganchos son escasos y de tamaño menor (Fig n Agrostis tolucensis Kunth y Festuca tolucensis Kunth
(Figs. 28 y 29) poseen peq dio en la región costal. Poa annua L. (Fig. 31) exhibe
escasos aguijones en E margen de n lámina y, en otras especies los aguijones están ausentes Asimismo, las
especies subalpinas carecen de micropelos bicelulares y macropelos. Estos rasgos sugieren que las especies
subalpinas no están expuestas a fuertes vientos o heladas frecuentes, como ocurre con las alpinas, por lo
que no requieren de una fuerte protección.
El tamaño pequeño de los ganchos y la ausencia de micropelos y macropelos hace suponer que estas
especies no requieren evitar la pérdida de agua pues los árboles de los bosques les proveen de sombra, tem-
peratura y humedad estables (Rzedowski 1978) por lo que la evapotranspiración, a través de los estomas, es
baja (Salisbury y Ross 1994). La ausencia de aguijones (en la mayoría de las especies), micropelos y macro-
pelos sugiere que estas especies no están expuestas a sequía (Gómez-Sánchez y Koch 1998; Nava-Rojo et
al. 2002), o al menos no a condiciones tan adversas como sucede con las especies alpinas. Esta condición
contrasta con la presencia de aguijones, micro y macropelos en especies alpinas y también en aquellas de
zonas desérticas.
Los estomas están dispuestos en una o varias hileras (Figs. 30 y 31). En ocasiones, los estomas no están
visibles, probablemente porque están cubiertos por los escasos aguijones, están inmersos en el mesófilo y
éste se eliminó durante el proceso de aislamiento de la epidermis, o bien están confinados a los surcos de
la lámina.
En la mayoría de las especies subalpinas, los cuerpos de sílice son escasos y/o pequeños y se observan
en forma de hígado (Fig. 33), alargados (Figs. 27, 28 y 32) y redondos o cuadrados (Fig. 34). Este carácter está
asociado a las paredes anticlinales de las células largas lisas (Figs. 27, 31 y 32) y ambos rasgos, permiten que
las láminas sean laxas y menos rígidas que aquellas de las especies alpinas, lo que coincide con la opinión
de Ellis (1979).

De acuerdo con el criterio de Ellis (1976), la ausencia de costillas y surcos en la lamina de especies
como Dissanthelium californicum (Nutt.) Benth. (Fig. 41) o Poa annua L. (Fig. 42), o costillas y surcos leve-
mente pronunciadas como en Festuca tolucensis Kunth (Fig. 37), se asocian con la apertura completa de la
lámina lo que sugiere que estas especies no están expuestas a la radiación solar por periodos prolongados
o la intensidad de la luz solar no es extrema. Festuca livida (Kunth) Willd. ex Spreng. (Fig. 35) y las tres
especies de Agrostis (Figs. 38, 39 y 40) muestran surcos y costillas pronunciadas, no obstante, la cantidad

que las especies disponen de buena condición hídrica.
Agrostis subpatens Hitchc., Dissanthelium californicum y Poa annua (Figs. 39, 41 y 42) tienen una quilla,
sin embargo, en la primera especie la quilla está provista de una pequeña hebra de esclerénquima, en la
segunda el esclerénquima está ausente y, en la tercera, la quilla tiene solamente un pequeño cúmulo de
células de esclerénquima. En los tres casos, la quilla solamente es un elemento que da forma a la lámina y
proporciona un ligero sostén (Ellis 1976).

Phleum alpinum (Fig. 36) y Poa annua (Fig. 42) muestran células buliformes dispuestas en abanico y
ocupan la mitad o más de la mitad del grosor de la lámina. No obstante, las células buliformes en la mayoría
de las especies subalpinas son de menor tamaño que aquellas de las especies alpinas, lo cual sugiere que la
involución de la lámina ocurre en menor grado que en las especies alpinas, puesto que no están expuestas
a una pérdida excesiva de agua.
En contraste con el grupo alpino, las especies subalpinas estudiadas carecen de células incoloras y
tienen anatomía no-Kranz y metabolismo C,. Esta condición también es típica en especies que crecen en
climas templados y presume que las especies subalpinas reciben luz en cantidad e intensidad adecuadas
(Ellis 1976; Hattersley y Watson 1975; Nava-Rojo et al. 2002).
Dissanthelium californicum (Fig. 33), Festuca livida (Fig. 34), F. tolucensis (Fig. 29) y Phleum alpinum (Fig.
30) tienen, en su epidermis, células largas con paredes anticlinales profundamente sinuosas y numerosos
cuerpos de sílice como el grupo de especies alpinas. No obstante y como el resto de las especies subalpinas,
carecen de aguijones o cuando existen son cortos y de paredes delgadas poco lignificadas, en su estructura
interna el esclerénquima es escaso y el mesófilo es conspicuo, mismo que se dispone de manera irregular
y sus células son grandes, aumentando así el grosor de la lámina lo que sugiere una presencia de humedad
estable (Ellis 1976).
Festuca tolucensis muestra una combinación de caracteres tanto de especies alpinas como de las sub-
alpinas. Esta especie exhibe, en su estructura interna, pequerias trabas abaxiales de esclerénquima que

grosor de la lámina es menor, el clorénquima y la cantidad de estomas se reducen, y los aguijones aumentan
su tamaño y el grosor de sus paredes. Especies, como Muhlenbergia nigra, M. orophila y M. quadridentata tienen
anatomía Kranz y una fisiología alterna, la C, Estos rasgos les permiten tolerar las distintas condiciones
extremas (Ellis 1977 y Salisbury y Ross 1994) que prosperan en estos ambientes de alta montaña. Dadas
las condiciones tan especiales que imperan en los ambientes de alta montaña, es posible que otras especies
alpinas y subalpinas tengan distintos patrones anatómicos a los descritos aquí, lo cual podría confirmarse
estudiando un número más amplio de especies.

As long as Botanists have collected plants, new and innovative methods have been developed to dry and
preserve specimens that retain as much of the natural integrity of the living plant as possible (cf. Smith et
al. 1886). Results of the progress in pressing, drying, and preserving methods are readily apparent upon
viewing a series of herbarium specimens covering several generations of botanical collectors. The standard
methodology employing newsprint, blotters, corrugated cardboard, and heat has been used for several de-
cades to dry specimens, and details about composition, construction, and procedures for drying specimens
are provided by a number of authors (e.g., Fosberg & Sachet 1965; Simpson 2006; Carter et al. 2007).
Various materials and methods including metal tubes or cans (vascula), cloth sacks, Styrofoam ice
chests, and paper and plastic bags have been used to transport specimens from the field to drying presses,
Alternatively, heavy and Aa besote Mi presses may be taken directly to the field; however, their use is
often prohibited by terrain, dis! d, and adverse weather liti Several field 1 (portfolio)
designs have been used over the years, iedig that of Fosberg and Sachet (1965). Haynes 2006) described
a field press made from several pieces of cardboard corrugate cinched with a press strap. In the early 1990s,
Dr. Anton A. Reznicek, curator of vascular plants at the University of Michigan, constructed a field press of
cardboard and duct tape and secured with a cord, which was light weight and easy to use under most field
conditions. During a field trip to centra l Arkansas in 1993 with Dr. Reznicek, Dr. Paul Rothrock, and Philip
Hyatt, Dr. Reznicek was observed using a cardboard and rope press. Immediately after this field trip, the
senior author constructed a prototype of the press described herein out of heavy cloth and rope. Over the
years this cloth press has been modified to increase the ease of use and to perfect the overall dimensions.
The second author has successfully improvised a variation on Dr. Reznicek’s field press by cutting down
corners of a cardboard carton and using the sides and top flaps, still attached, to hold specimens enfolded
in newsprint.

ard, plywood, or other field supplies.
10. Pin Velero to the cloth using care to align corresponding pieces on each side. Note that Velcro strips are
ached to opposite sides of the cloth on opposing flaps.
11. Stitch around the edge of each piece of Velcro twice and tie thread ends. Strips of Velcro at least 5 cm wide
provide better field press closure than narrower strips.
12. Remove all pins and the field press is ready to use.
DISCUSSION
The field press described herein (Fig. 1) is the result of over 15 years of field testing by the authors and
except for its size and more permanent materials is based on Dr. Reznicek's initial concept. Durable, light
weight, and washable, it is easy to use in a variety of field situations (Fig. 2). The press can be carried under
the arm or attached to a back pack, an all terrain vehicle (ATV), or a saddle. It is also convenient for press-

ing and transporting plants in a boat or canoe where a conventional press is too heavy or bulky. It is useful
for pressing large numbers of specimens rapidly and for pressing plants that wilt rapidly or lose floral parts
upon harvesting. The capacity of the press varies depending on the length of the press flaps and thickness

weight polyester or other synthetic fabric may be substituted for cotton to make the field press suitable for
field work in tropical areas or environments with constant moisture. Although extra cardboard corrugates,
plywood, or felt blotters add weight and bulk, they can be used in the field press. Three heavy pieces of
corrugated cardboard (one on top, one on bottom, and one between newsprint and the pressed specimens)
provide the lightest weight, while allowing for adequate handling of specimens. Additional corrugates can
be used to separate sp from different collection sites or to separate pre-numbered and unnumbered
newsprint. We developed a system of pressing the first specimen in pre-numbered newsprint and the du-
plicates in unnumbered newsprint. When these are placed into a conventional drying press from the top to
bottom of each stack from the field press, the numbered newsprint is removed first from the conventional
drying press. Thus, the duplicates can be easily tucked into the folded numbered sheet. Unknown to us,
Dr. John Thieret and his students used a similar numbering technique (Haynes 2006).

Specimens are pressed between newsprint and stacked on top of one another with one piece of cor-

by pressing the Velcro strips on the first set of flaps against those on the opposing set. Next the second set
of opposing flaps is closed and secured. Two sets of opposing flaps allow for greater pressure on the stacked
specimens, hold specimens in place within the newsprint, and provide pressure on plant parts that were
folded over in fitting the specimen to newsprint sheets. With this field press, unlike vascula, cloth sacks,

fruits or other structures. Precautions should be taken to keep loaded field presses as cool as possible and
out of direct sunlight. For optimal results, plants should be taken from the field press and placed in drying
presses as soon as possible, e.g. at the end of each day. However, the time in the field press can be extended
depending upon environmental conditions and the kinds of plants being pressed. Plants such as grasses
and sedges may remain in the field press longer than plants that are subject to discoloration or contain high
water content, and specimens may be kept in the field press under refrigeration overnight with no discern-
able ill effects. Although not led, in unusual circumstances of exigency, we have kept specimens

INTRODUCTION
Kaieteur National Park (Fig. 1), the only national park in Guyana, is located approximately 230 km southwest
(5° 10' 42" N; 59° 29' 44" W) of Georgetown, the nation’s capital. The park is situated on an upland region
of Guyana known as the Potaro Plateau of the Pakaraima Mountains. This plateau is an eastern extension
of the largely Venezuelan Roraima sandstone formation that forms the flat table-top mountains known
as tepuis. The Potaro River flowing over this plateau has cut a 20 km gorge in the easternmost portion of
the Roraima formation. The river eventually plunges 226 meters via a single drop into the gorge. Kaieteur
Falls is one of the most spectacular cataracts in the world and is the main geological feature of the national

park. The park was established in 1929 and encompassed 44 km" to protect the area around the falls, the
Potaro gorge, and the surrounding Potaro Plateau. Today the park has been expanded to 627 km! to protect
a greater representation of the vegetation around the falls and a larger expanse of the savannas and forests
of the plateau. In 1998, the park was incorporated into the National Protected Areas System (NPAS) that
is currently being developed as part of Guyana’s ecotourism business. With this NPAS Project, Guyana
urgently needs information on the biodiversity of the area before any conservation or management policy
can be implemented. Botanical exploration of the mid- to lower portions of the drainage has been limited
to the area around the falls and along the Potaro gorge; such exploration has resulted in a checklist of the
vascular plants of the area (Kelloff & Funk 1998), but there have been virtually no ecological studies in an
attempt to quantify species A
In general, tropical forest ] ized as having a high diversity of trees, with some inven-
tories recording over 300 species with a diameter at breast height (DBH) > 10 cm per hectare (Gentry 1988;
Hubbell & Foster 1986; Valencia et al. 1994). Several hypotheses offer explanations regarding the mainte-
nance of high diversity. Huston's (1979, SE ee E SUOMI SUEESSIS that UNE in
populations is reached by low rat (Hustor
1979). If the population has a high dumber or high frequency of a Doing species will
disappear and be replaced by the faster-growing pioneer species over time thus reducing diversity. In order
to overcome this species must have some minimum growth rate to recover from population reductions. In
other words, an increase in growth rates during periods of high frequencies of population reduction can
actually increase diversity (Huston 1979). Another hypothesis is an ecological response to environmental
conditions such as low and high light conditions. By changing the availability of resources, disturbances
such as canopy gaps may influence succession. Those species efficient in recruitment quickly move in, and
the site becomes 1 with pi (Bazzaz & Picket 1979). The ability to survive under low light
conditions and the ap) to achieve high growth under high light conditions is the most significant differ-
ence between species diversity (Bazzaz & Picket 1979; Hubbell 1995). It's the survival of the fittest that can
utilize the disturbance, increasing the diversity of species. In Guyana, Dicymbe Spruce ex Benth., which is
locally known as clump wallaba, produces coppices (suckers) on the healthy parent tree. When Gs parent
trees die, these young trees can take advantage of the mature root system of the parent, as well as the light
gap, and thus can out-compete other species in the area (Henkel 2003; ter Steege et al. 1993).
Not all tropical forests show a high alpha tree diversity, however. Productivity and disturbance vary in
the tropics (Richards 1952; Connell & Lowman 1989), and this is evident in the mixed forests of central
Guyana where there is a tendency for some species to dominate the vegetation (Davis & Richards 1934;
Fanshawe 1952; Johnston & Gillman 1995; ter Steege 1993). Severa lexamp les of this type of forest in Guyana
are the wallaba (Eperua Aubl.), mora (Mora Benth.), or clump wallaba (Dicymbe) forests (Davis & Richards
1934; Fanshawe 1954; Henkel 2003; ter Steege 2000b). These forests have a few species that represent a
high percentage of the stems and/or basal area.
The tropical forest of Guyana contains a wide array of forest types, e.g., mangrove, moist and dry ever-
green, montane, seasonal, swamp, and Greenheart forests. In swamp and mangrove forests, edaphic factors
such as flooding and soil clearly explain these forest types (Fanshawe 1952). However, in the mixed forests
of Guyana, the relationship between soil, hydrology, and forest types is not clear (ter Steege et al. 1993).
Generally, classification of forest types has largely been based on climate, soil, and physiognomy (Ducke &
Black 1954; Prance 1987), which reference species compositions or have generalized tropical floras at the
genus or family level (Forero & Gentry 1988; Maguire 1970; ter Steege et al. 20002). Recent studies used
plots to examine patterns of plant diversity, e.g., how species richness (Gentry 1988) or habitat diversity
contributes to species diversity (ter Steege 1993; Sabatier et al. 1997; Tuomisto & Ruokolainen 1997). Plot
studies produce data at the species level and can provide long-term information on growth, mortality, re-
generation, and dynamics of forest trees.
Sampling riparian trees of the plateau using a grid system of collecting allows us to (1) describe the

relative abundance and distribution of the trees, (2) provide a framework by which the forest structure of
Kaieteur can be compared to other known study sites, (3) help fill in the missing tree taxa in the checklist,
and (4) provide a standard by which forest structure and composition can be measured.
This paper presents the results of the two, one-hectare (ha) inventories carried out on the Potaro
Plateau within Kaieteur National Park. Tree data from two other plot studies were used as a comparison of
the tree diversity at Kaieteur. Data from two one ha plots were borrowed from a lowland forest in Guyana
near the town of Kwakwani (a Guiana Shield community) and two one ha portions of a 50 ha plot at Barro
Colorado Island, Panama (non-Guiana Shield community. In general, plot data from the Guiana Shield
and particularly the Potaro Plateau are scarce (ter Steege et al. 20002). One ha plots allow for us to quantify
the relationship between tree species as well as among tree species and add to the knowledge of the tree
diversity of Potaro Plateau in Guyana. The ultimate goal of this project was to document the species diversity
and tree composition of the Wallaba (Eperua)-mixed forests of the Potaro Plateau and to compare the tree
species diversity of Kaieteur National Park to those of other plots.

scrub, E riparian forests. The average air temperature for the "— is 26. 5°C (USDA 1974). The average
rainfall for the northeast face of the ai escarpment is approximately 3750 mm per year (Fanshawe
1953). Two 1 ha plots blished in the Wallaba (Eperua)-mixed forest of the Potaro Plateau. The study
was conducted between 1995 and 1998 with sites selected based on the surrounding vegetation. In both
1 ha plots, some level of previous human disturbance was found (e.g. several large trees were removed for
the building of the guesthouse). The first plot (Fig. 2a) is located at the headwaters of the Korume Creek
(5º10'42"N, 59°29'44"W). The lower portion of the first plot is seasonally inundated and includes a portion
of the creek in which grew a few patches of Thurnia sphaerocephala (Rudge) Hook.f. Along the western side
of the plot, the land gradually rises up tl ine towards Muri-Muri savanna. The second plot (Fig. 2b) was
established in the upland forest of the plateau between the Korume Creek and Potaro River gorge (5*11'16'N,
59º28'52"W). The terrain is rocky with a slight downward slope towards the northeastern part of the trail.
There is no evidence of seasonal flooding as in the first plot.
The soils from these two sites were not analyzed, but it was generally observed that they consisted of a
course white sand of quartzite with very little peat. These shallow white sand areas of the Pakaraima Plateau
(Fanshawe 1954) are associated with the peneplain of the interior of Guyana.
The plots in the lowland area of Guyana used for comparison are located near the town of Kwakwani at
the Aroaima (bauxite) mining site on the Berbice River, 238 km up the canje! ave from New Amsterdam
(5°30'N, 58°W). Data for these plots were kindly provided by James Comiskey (Smi ian Institution Man
in the BioSphere Program). The average rainfall recorded for this area is 2400 mm per year. The land is low
lying with swampy areas near the river. The sites for the plots were selected within the area designated as
"south mine," a proposed area for future bauxite mining. In this area, the shallow layer of topsoil (averaging
1.5 meters in depth) covers ca. nine meters of bauxite that overlays 60 meters of volcanic rock. Both plots
were irregular in shape, and the vegetation is classified as non-flooded tropical mixed forest (Comiskey et
al. 1994). It was noted that the soil was composed of a mixture of sand and clay with high porosity and high
drainage. The soils were not sampled (Comiskey et al. 1993).
The second set of plots were part of a 50 ha study site at Barro Colorado Island (BCD located near the
Panama Canal at the Smithsonian Tropical Research Institution’s station (9°9'17"N, 79°50'53"W). This for-
est is classified as a rich, old growth tropical forest dominated by Bombacaceae and Leguminosae (Condit
et al. 1996). The terrain on the island's summit is relatively level with a variance of 28 meters in elevation.
The average rainfall for this area is about 2500 mm per year (Condit et al. 1996) with a mean annual tem-
perature of 27°C. The soil at BCI is a clay-rich tropical soil with an organic matter content (Yavitt 2000).
Data from two of the 50 1 ha plots (designated as Hec21 & Hec37) were selected and kindly provided by
Richard Condit for this study.

The two 1 ha plots at Kaieteur were subdivided into 25 M 20 x 20m quadrats, end all stems with a

mapping purposes. Field vouchers were obtained, where possible, for each species encountered. Information

Density, frequency, and dominance were calculated to describe how individual species are spatially
distributed within the plot and how these distributions contribute to the community (Barbour et al. 1987).
Stem basal area (a) and density of each tree were calculated using a = 0.7854 x (DBH) 2, where a = basal
area of each tree in m? (Anderson & Ingram 1989). This measurement is useful in estimating canopy cover
of trees because it assumes to take trunk diameter at breast height (DBH) into account. We also calcu-
lated species basal area (BA), defined as the sum of all stem basal areas (a) of a given species. Density is
defined as the number of trees per hectare, and relative density is the percentage of one species in relation
to the total plant diversity. Relative frequency is expressed as a percentage of the number of quadrats that
contain a given species. Dominance is an important ecological t. A species that | the
most cover or basal area to the community is considered the dominant species. Dominance is calculated
as the percent of basal area oh a given species to ota! vn area Mimi et al. E
Finally, the relative tion that ity is called its importance value
(Balslev et al. 1987). The importance value iudex (IVI) can be calculated by the addition of the relative
density, frequency, and dominance for each species and for all trees at each site. High IVI values indicate
that a species has a high basal area, frequency, and density at a site or when one or two of these parameters
are much higher than other species (Felfili & da Silva 1993). The sum of relative parameters places species
in a hierarchical order in the community and is useful for comparisons between different sites (Curtis &
McIntosh 1951; Felfili & da Silva 1993). The IVI values can range from 0 to 300, with 300 representing a
pure stand of one species (Balsiev et al. 1987).

data into a space with fewer Ge Es can reflect sample configurations in e space (Gauch
& Whittaker 1981). In community ecology, such ordinations can describe some of the strongest patterns
in species composition (McCune & Mefford 1999; McCune & Grace 2002). Ecologists have applied metric
ordination, which includes principal components analysis (PCA), to analyze vegetation data (Proctor 1967;
Debinski & Brussard 1994; Tuomisto et al. 2003). This type of ordination assumes a linear relationship
between the variables and is rarely amenable to ecological community data; it can also lead to consider-
able obscurity in data interpretations (Goodall 1953). Non-metric ordination methods are considered more
powerful for analvzing vegetation data because this method assumes a non-linear relationship between the
Kelloff, Kaieteur National Park, Guyana 527
variables and the use of ranked dist tends to li ize t] lationship between the distances measured
in environmental space and species space (McCune & Mefford 1999).
Species data per plot were ized into data matrices (taxon vs. quadrat) and imported into PC-Ord
(McCune & Grace 2002), a multivariant statistical program. Because the data represent quantitative scores
per taxon, the original values were log transformed using b; = log(x; + 1), where the value of one is added
to each species score to define zero values in the data. Log transformation reduces any dominant effects and
normalizes the relative importance of common or rare species (Digby & Kempton 1987; McCune & Grace
2002). To visualize multivariate patterns among the quadrats, non-metric multidimensional scaling (NMS)
was conducted using Sgrensen (Bray-Curtis) distances for each plot and on each plot pair. NMS in PC-Ord
is based on Mather's (1976) program and the algorithm of Kruskal (1964).
For each dataset in this study, the "autopilot" mode in PC-Ord was used. This mode provided a random
starting configuration for each run. The program calculates each solution by running 40 runs with the real
data and 50 runs with the randomized aa, wa a maximum number of 400 iterations for six axes. The
program selected the best solution at each where p < 0.05 for the Monte Carlo test and where
that value of the “stress” parameter was t I anes Clarke’s (1993) “rules of thumb” were used to
interpret the final stress. Clarke found that most ecological community data will have values with a final
stress between 10 and 20.
MS provides an optimal ordination technique to analyze patterns in tree species composition for each
of the studies. The Anal: result in each analysis was an ordination in two-dimensional space. The two axes
show the relationship between species abundance and the axis score.
RESULIS
Kaieteur National Park, Guyana.—There were 1724 total number of stems 210 cm DBH at Kaieteur in the
two study plots. These stems covered a total basal area of 66.34 m?/ha. Plot KF1 at Kaieteur contained 757
stems per hectare, with most taxa b dea Dy a Ld stem. Dicymbe pharangophila R.S. Cowan (swamp
wallaba, Leguminosae—Caesal.) produced coppice the base of the trunk that resulted in 65 stems
being measured and tagged froin a total of 28 trees. This habit of producing multiple stems from the base
was also noted by Whitton (1962) and Henkel (2003) of Dicymbe corymbosa Spruce ex Bentham, another
“swamp wallaba” found on the Potaro Plateau. The largest diameter tree recorded for the site was Ocotea sp.
(Lauraceae), with a DBH of BN cm. cn EE with a DBH > 60 cm were Pouteria cf. cuspidata (A. DC.)
Baehni (Sapot ) and S ; ii Bentham (Leguminosae—Fab.). Sixty-four percent of the stems
were ani 20 cm in ees and abner one percent of the trees reached over 60 cm DBH. The two species
that had the highest Important Value Index (IVI) were Chamaecrista adiantifolia (Spruce ex Bentham) H.S.
Irwin & Barneby var. pteridophylla (Sandwith) H.S. Irwin & Barneby (Caesal.; IVI-20.052) and Eperua falcata
Aublet, (Caesal.; IVI-15.427). These two species were found throughout the plot and accounted for 13.4%
of the stems. Dicymbe pharangophila (IV1214.679), Ormosia coutinnoi Ducke (Fab.; IVI=10.109), Dicymbe sp.
(1V1=10.027) and Pouteria cuspidata (IV1=10.442) ranked next in importance. These species accounted for
32% a ine stems recorded for KF1. |
species were not recorded, but it was noted that t
sp. and Meno ama spicatum (Aublet) J.F. Macbride) dominated the loners wet areas of the plot. RE Species
of Bromeliaceae (Ananas parguazensis L.A. Canargo & L.B. Smith) dominated the dryer soils of the plot.
Thurnia spherocephala (Ridge) Hooker f. (Thurniaceae) was quite abundant and grew in the flowing waters
of the creek.
The second plot (KF2) at Kaieteur had more stems (967) than the first plot. Dicymbe pharangophila was
neatly absent from this plot. Chamaecrista adiantifolia var. pteridophylla (95 cm DBH) and Swartzia schom-
burgkii Bentham (Fab.; 92 cm DBH) were the largest trees recorded for the site, followed by Elizabetha sp.
(Caesal.; 66 cm DBH) and Pouteria cuspitata (64 cm DBH). Stems 20 cm DBH or less accounted for 69.596,
whereas only 1.096 of the stems exceeded 60 cm in diameter. Several species ranked high in IVI: Eperua

Swartzia schomburgkii (IVI=17.404). When Catostemma commune Sandw. (Bombaceae; IVI 215.082), Ormosia
coutinnoi (IVI212.328), and Eperua spp. (IVI215.702) are added, these species account for 40.396 of the total
stems EH for "ped KF2. The understory species were not surveyed, but it was noted that Ishnosiphon
sp. and M somewhat evenly distributed in the plot. Vriesea splendens (Brongn.) Lem.
E DEER was seen along with the spiny bromeliad (Ananas parguazensis) from the first plot but was
not as abundant. A broad-leaf aroid grew on tree trunks, and a Rapateaceae (Stegolepis ferruginea Baker f.)
dominated the understory at quadrat 14.
In both plots at Kaieteur, the Leguminosae had the highest number of individuals per site (815 stems
or 47.396 of the plots) most of which were from the subfamily Caesalpiniodeae (607). In plot 1 Bombacaceae
ranked as the second most abundant family across all quadrats with 64 stems. Bombaceae, in plot 2, had
77 stems but ranked third after Lauraceae (136 stems).
Kwakwani, Guyana.—There were a total of 995 stems > 10 cm DBH at Kwakwani in the two plots, these
with a total basal area of 52.13 m?/ha. Five hundred and seven stems were recorded from first plot (ART)
at Kwakwani. Only four trees had a second stem measuring over 10 cm DBH. The largest tree on the site
was Trymatococcus amazonicus Poepp. & Endl. (Moraceae) at 91 cm DBH. Eschweilera pedicellata (Rich.) S.A.
Mori (Lechythidaceae) represented 23% of the total stems (115 stems) in this plot and had an IVI of 33.425.
The taxon with the next highest IVI (6.751) was Aspidosperma excelsum Benth. (Apocynaceae) followed by
Bocageopsis WER Dee ) R.E. Fr. (Annonaceae; 6.733), Unonopsis rufescens (Baill.) R.E. Fr. (Annonaceae;
kii (Fab.; 5.116), Prunus sp. (Rosaceae; 3.857), and finally Cordia sagotti I.M. Johnst.
(Garip mace 3.795). These taxa reseed 163 stems or 21% of the stems counted in the site. Sixty three
percent of the stems were under 20 cm di a only 2% were over i cm DBH: Me pedicellata
(I thid - 88.2 cm), Aspid (Sp ex Benth.)
plam NE mass 83.5 cm), Inga pna Benth. MAE 76 Em And Bocageopsis multiflora
(Mart.) R.E. Fr. (Annonaceae; 72.8 cm
The second plot (AR2) at Kwakwani had only 491 trees of single recordable stems. Aspidosperma excel-
sum was the largest tree (91 cm) and Eschweilera pedicellata had the highest IVI value of 63.671 (138 stems,
2896 of the total stems). Two other taxa significant were Mora gonggrijpii (Kleinhoonte) Sandw. (Caesal.;
1V1=36.486) and Aspidosperma excelsum (IVI-15.600). Inga acrocephala Steud. (Mimos.), Mora gonggrijpii,
Swartzia polyphylla DC. (Fab.), Eschweilera pedicellata, Chrysophyllum sparciflorum Klotzsch ex Miq. (Sapota-
ceae), and Aspidosperma excelsum represented the 396 of the total stems over 60 cm DBH. Fifty-six percent
of the total stems were under 20 cm.
Lecythidaceae was the most abundant family at Kwakwani, with 254 stems documented for the two
plots. Leguminosae was tl ond most abundant with 184 stems (107 of these were Caesalpinioids in site
2). Next in rank were the Annonaceae with 55 stems over all quadrats in ARI and Boraginaceae (34 stems).
In site 2 these families represented only 19 and 2 stems. Apocynaceae had more stems (26) in AR2 and
ranked third in abundance across the plot. All other families had less stems.
Barro Colorado Island, Panama.—1n the two 1 ha plots selected from the Barro Colorado Island (BCT) 50
ha plot, the total basal area of trees > 10 cm was 57.153 m?/ha. Information provided for this study includes
only data for the main stem on each plot. No data were available for multiple stems and thus these were
excluded from this study. The first plot (designated as Hec21 at BCI) had 418 trees. The tree that had the
largest diameter on the site was Hura crepitans L. (Euphorbiaceae; 102.1 cm DBH). Seventy-five percent of
the trees had « 20 cm DBH. Two percent of trees had a DBH » 60 cm: Brosimum alicastrum Sw. (Moraceae;
88.5 cm); Chrysophyllum cainito L. (Sapotaceae; 88.5), Jacaranda copaia (Aubl.) D. Don (82 cm) and Tabebuia
guayacan (Seem.) Hemsl. (Bignoniaceae; 82 cm); Prioria copaifera, (Caesal.; 82 cm); and Luehea seemannii
Triana & Planch. (Tiliaceae; 76.8 cm). The dominant species for Hec21 were Faramea occidentalis (L) A.
Rich. (Rubiaceae; IVI = 18.644), Trichilia tuberculata (Triana & Planch.) C.DC. (Meliaceae; IVI = 23.870),
Kelloff, Kaieteur National Park, Guyana 529
Prioria copaifera, (Caesal.; IVI = 17.581), and Alseis blackiana Hemsl. (Rubiaceae; IVI = 10.344). These taxa
accounted for 139 trees or one-third of the entire tree census.
The second plot (designated as Hec37 at BCI) contained 447 recordable trees, 62.6% of which were < 20
cm DBH. Ceiba pentandra (L.) Gaertn. (Bombacaceae) was the largest tree in the plot with a diameter of 209.5
cm DBH. Other species over 60 cm DBH were Ficus costaricana eoe o (Moraceae, 138 cm), Tachigali
versicolor Standl. & L.O. Williams (Caesal.; 109.1 cm), Hura ; 99.4 cm), Aspidosperma
cruenta Woodson (Apocynaceae; 89.0 cm), Dendropanax arbores (L) Been & Planch. (Araliaceae; 83.0
cm), Brosimum alicastrum Sw. (Moraceae; 75.3 cm), and Cecropia insignis Liebm. (Cecropiaceae; 66.0 cm);
Guapira standleyana Woodson (Nyctaginaceae; 75.3 cm); SE EE Pittier (Bombacaceae; 69.8
cm); and Guatteria dumetorum R.E. Fr. (Annonaceae; 63.5 cm). The t species on the site were Faramea
occidentalis (IVI = 23.340) and Trichilia tuberculata (IVI=27.239); together, these two accounted for almost
31% of the total countable stems. Other species with high IVI values were two Bombacaceae: Quararibea
asterolepis (IVI=14.721) and Ceiba pentandra (IVI-12.455).
From the two plots examined at Barro Colorado Island, Rubiaceae ranked the highest for individual
stems (217). Meliaceae, with 122 trees, ranked second in the "tree per family" category. The Leguminosae
contained only 67 stems, 47 of which were Caesalpinioids.
A comparative summary of the most abundant tree species from the six study sites can be found in
Table 1.

of the three study sites. In each plot there were several mm that id a strong relationship with
the ordination scores. These species were displayed on the ordination as a joint plot. The radiating lines
of the joint plot reflect the direction and strength of that species that is influencing the separation of the
quadrats in the plot. Plot KF1 at Kaieteur had 103 species in the analyses. The final stress was 15.68692
for the 3-D solution with 99 iterations. The Monte Carlo test for this solution was p < 0.0196. The first two
axes accounted for 56.8% of the variance; the first three accounted for 74.1%. Three patterns are seen in
the grouping of quadrats based on species assemblages (Fig. 3A). Dicymbe spp., Chamaecrista adiantifolia
var. pteridophylla, Pachira flaviflora (Pulle) Fern. Alnso. (Bombacaceae) form one group, and Chamaecrista
apoucouita (Aubl.) H.S. Irwin & Barneby (Caesal.) and Pterocarpus rohrii Vahl (Fab.) form a second group;
these two groups have a stronger influence in some of the quadrats whereas a third group composed of
Hevea guianensis Aubl. (Euphorbiaceae), Inga gracilifolia Ducke (Mimos.) and species in Meliaceae have a
stronger influence on others.
Kaieteur plot KF2 had the fewest species (71) in the dataset. The best result for the dataset is the 3-D
ordination from NMS with a stress value of 13.30984 with 162 iterations (Monte Carlo p < 0.0196). The
variance for the first two axes accounted for 66.496 of the variance; if the third axis is included, 82.596 of
the variance is accounted for. Quadrats in the EE are an into speci lages influenced by two
groups: the Licania alba (Bernoulli) Cuatrec. (Chry pp., Clathrotropis macrocarpa
Ducke (Fab.), Eschweilara spp., Ocotea spp., and Macrolobium iaa Spruce ex Benth. (Caesal.) group;
and the Henrettea ramiflora (Sw.) DC. (Melastomataceae), Sextonia rubra (Mez) van der Werff (Lauraceae),

a
Inga sp.3, and Catostemma Sandw. (Bombacaceae) in the other (Fig. 3B).
Combining the data from the two plots at Kaieteur, the best result from multiple NMS runs was a 3-D
solution (stress = 18.09208, p < 0.0195) with a variance for the first two axes ting for 54.696 or 75.096
including the third. The first two axes were chosen for the ordination to best represent the data (Fig. 3C).
Axis 1 represents the area of collection and EES in a between the locations of the plots. Axis
2 represents a clear separation between tl an ges at plots KF1 and KF2. Species that
contributed to the discrimination in dein were DIOE i a a Eperua rubiginosa Miq. (Caesal), and
Catostemma fragrans Benth. (Boml g to discrimination in KF2 were Fperua spp.,
Sextonia rubra, Henriettea UM and Gesten spp. There was no overlap in species composition between
quadrats of these two plots.

Ordination was used to reduce the datasets at the Kwakwani study site. Site ARI had 84 species with
a final analysis in a 3-D solution of 15.71292 (stress) over 82 iterations (p < 0.0196). The overall patterns
between the quadrats indicate some differences in species composition between the plots. The quadrats

At site AR2, there were 58 species in the matrix were abun-

find a useful ordination. Esch llata an i were deleted for remaining calculations.
The result was a 4-D solution (stress = 13.80266; p < 0. 0392) for this plot (Fig. 3E). The first two axes ac-
counted for 18.7%, and the third added only 34.6% of the variance. These blages were defined by the
following species in the plot: Miconia hypoleuca (Benth.) Triana (Melastomataceae), Inga pezizifera Benth.
(Mimos.), Prunus sp. al Chl DIDI rodiei (R.H. Schomb.) Rohwer, H.G. Richt. & van der Werff

At the Barro Colorado Island (BCI) Hec21 plot, a total of 92 species was observed. The final stress
for the 3-D solution was 15.82730 (p < 0.0196) in 88 iterations. The first two axes accounted for 49.2% of
the variance (73.896 with all three). Figure 4A shows the result of the non-metric scaling. The angle and

The BCI plot Hec37 had 82 species; the ordination had a final stress of 17.47696 over 131 iterations
(p < 0.0392). The first two axes accounted for 30.5% of the variance and the first three, 61.1% of variance.
The species that contributed to discrimination in this plot were Trichilia tuberculata, Virola sebifera Aubl.
(Myristicaceae), Cecropia insignis, Aspidosperma cruenta, Alseis blackiana, Brosimum alicastrum, and Guapira
standleyana (Fig. 4B).
A total of 114 species in the two BCI plots was observed. The resulting ordination of the combined
plots produced a 3-dimensional solution with a stress of 21.77097 (p « 0.0392) in 400 iterations. The vari-
ance explained by the first two axes was 33.696 and 58.196 including the third. The quadrats of the two
plots overlapped significantly, indicating a similarity of species composition within each plot (Fig. 4C). The
species with the strongest relationship in this ordination were Trichilia tuberculata, Adelia triloba Hemsl.

DISCUSSION
Establishing two permanent biodiversity monitoring plots at Kaieteur National Park has provided Guy-
ana with the scientific data required for the prioritization of conservation initiatives. This study provides
baseline data on tropical woody plant communities to aid in measuring ecological change over time and to
help distinguish between natural and human impact. Measuring relative density, relative frequency, rela-
tive dominance, and importance index values of individual species provides information on how species

are DM Man the forest and how they contribute to the community in which they live. Using a
lology f. ing all trees > 10 cm DBH ensures comparability with other study sites
and provides a framework ior studying the dynamics of tropical forests. This survey at Kaieteur resulted
in 133 taxa representing 1586 trees (1,725 stems = 10 cm in DBH) almost twice the number of trees from
the Kwakwani, Guyana or Barro Colorado Island, Panama. The density of trees at Kaieteur were similar to
a caatinga forest on white sand at Pico da Neblina in Brazil where 1569 trees were measured in two one-
hectare plots (Boubli 2002). The number of stems recorded in each plot at Kaieteur bordered on the upper
range of stems per hectare (965 stems har!) found on similar plot studies. This high number of stems were
found by Davis and Richards (1933, 1934) in five plots at Moraballi Creek, Guyana (460 to 919 trees per
122 x 122 m plot) where as those of similar studies in the Neotropics for trees 2 10 cm DBH have not been.
Sabatier and Prévost (1990), Poncy et al. (1998), and Bordenave et al. (1998) found densities of 473 to 570
stems per hectare at Les Nouragues, French Guiana, and up to 882 stems per hectare in one particular
transect (Sabatier & Prévost 1990). Johnston and Gillman (1995) recorded 357 to 742 trees per hectare at
the four one-hectare study plots at Kurupukari, Guyana. At the El Caura Forest Reserve, South Venezuela,
mean densities ranged from 563-573 trees ha! (Castellanos 1998). In Manaus, Brazil mean densities were
550 stems ha! (Ferreira & Rankin-de-Mérona 1998)
Davis and Richards (1934) noted that the forest at Moraballi Creek dominated by Eperua falcata had
an extraordinary large number of trees ha! and that Leguminosae was the most abundant family (Whitton
1962). This was also noted by Boubli (2002) at Neblina where Eperua leucantha Benth. accounted for a large
percentage of the stems. Guyana’s rain forests can be dominated by one to several species, these often in
the same family (Davis & Richards 1933; Fanshawe 1952; Whitton 1962; Henkel 2003). Kwakwani's plots
were dominated by Lecythidaceae (30.9%) and Kaieteur's (47%) were dominated by Leguminosae. This is
not unique to Guyana as a Lecythidaceae or Leguminosae dominance can be found in many other tropical
forests, e.g., Richards 1952; Whitton 1962; ter MAN 1993; Nascimento & Proctor 1994; Henkel 2003.
Stem diameters were summarized into two categories (10 cm increments and percentage of stems per
class size) in order to facilitate comparisons between the study sites (Table 2). The distribution of tree per
class size in the six plots shows a characteristic inverse J-shape (Fig. 5) typical of forests that have been
relatively undisturbed in the recent past ER E Mori 1989), with over 5696 of the trees equal to or
less than 20 cm DBH. Overall, the stem class size tions from 20.1 cm to 60 cm DBH at Kaieteur were
comparatively similar to Kwakwani and BCI in this paper. Total p tage of stems below the 40.1 cm DBH
class in each of the three study sites ranged from a low of 86.7% at BCI to 95.9% at Kaieteur plot KF2. Boubli
(2002) commented that 46% of trees at Neblina were small in girth while Whitton (1962) commented that
in the Wallaba forests of Guyana, very few trees exceed 70 cm in diameter. At Kaieteur only ca. 2% reached
the larger diameters with only three species, these all Caesalpinioid legumes, reaching over 30 cm DBH:
Eperua falcata, Chamaecrista adiantifolia var. pteridophylla and Swartzia schomburgkii.
The total calculated basal area/ha from the three sites in this study ranged from 52 to 66 m? / ha.
Kwakwani and BCI were similar to the 53 m*/ha found by Whitton (1962) and Mori and Boom (1987) at
Saúl, French Guiana, but higher than those found in the forest plots (27-34 m?/ha) of Central Amazonia
(Rankin-de-Merona et al. 1992). Kaieteur’s total basal area (66 m*/ha) was similar to that of Neblina (Boubli
2002, 73 m%/ha).
In order to understand the importance value index (IVD of each species and how it contributes to the
community one has to look at its relative parameters. Of all the Caesalpiniodeae legumes at Kaieteur two
species, Eperua falcata and Chamaecrista adiantifolia var. po e a tota! IVI va of 75. K These

Kwakwani, the highest IVI values (119.5) for both sites came from one species al Lecythidaceae, Eschweilera
pedicellata. This species dominated the plots and was higher than the Lecythidaceae at La Fumée Mountain,
French Guiana (Mori & Boom 1987). Such high IVI values have only been recorded elsewhere by Gibbs
et al. (1980) for Cyclolobium vecchii A. Samp. ex Hoehne (Leguminosae; IVI=82) and Sebastiania klotschiana

When the plot data were examined at the family level, there were 33 families at Kaieteur and 36 at
Kwakwani. The number of families in the Guyana plots was lower than the number of families recorded
by Balslev et al. (1987) for the floodplain (44) and non-flooded forests (53) of Añangu, Ecuador. It was also
lower than the 42 families at BCI. Thirty-three percent of the families were found in all three study sites, with

When the average di ter at breast height of major tree families at Kaieteur, Kwakwani, and BCI were
compared (Fig. 7), the DBH ranged from 10.2 cm (Melastomataceae) to 47.7 cm (Bombacaceae). The largest
tree recorded among the research sites was an individual of Ceiba pentandra, Bombacaceae, from Hec37 at
Barro Colorado Island, with a DBH of 209.5 cm.
From the 325 taxa recorded for the three study sites, only 3% (10 species) of all species were shared
between the plots. Apeiba aspera, Brosimum alicastrum, and Virola surinamensis were shared between Barro
Colorado Island and Kwakwani. Catostemma fragrans, Licania alba, Swartzia schomburgkii, and Tapirira gui-
anensis were shared by Kwakwani and Kaieteur. BCI and Kaieteur shared only Pterocarpus rohrii. The only
species shared by all three sites was Jacaranda copaia. Thus, there is a substantial lack of overlap in species
composition among these tropical tree communities. Comparing genera among sites, only 6% were shared
among Kaieteur, Kwakwani and Barro Colorado Island. These were Aspidosperma, Inga, Jacaranda, Licania,
Ocotea, Pouteria, Protium, and Swartzia. When pair-wise comparisons were made between the sites, BCI and
Kwakwani shared 8.196 of their genera. Kwakwani and Kaieteur Falls shared 6.396 and 5.096 was shared
between BCI and Kaieteur. Based on a phytogeographical study of the taxa at Kaieteur, the flora of this area
has its strongest affinity (4296) with the Guiana Shield area of South America with only about 1596 of the
taxa having a widespread distribution across the Neotropics (Kelloff & Funk 2004).
Statistically, non-metric (NMS) ordination on ecological data derived from PC-ORD has helped to
describe the vegetation data from the plots at Kaieteur National Park and Kwakwani, Guyana and Barro
540 t tani i Texas 2(
Colorado Island, Panama. In all six plots, the first t lescribe the relationshi dissimilarity between
the quadrats (in ordinary space) and represent this variation in ordination space Nec & Grace 2002).
The quadrats with floristic similarities tend to form loose clusters. In the joint plots these similarities sug-
gest trends that can be indicators of microhabitats induced by substrate characteristics, hydrology and/or
other edaphic effects in the site. The Janzen-Connell model for tropical tree diversity proposes that seeds
and seedlings in proximity of conspecific adults are have a higher mortality rate resulting in recruitments
some distance from the parent tree leaving space for colonization by other species (Schupp 1992). Other
factors to consider are the ability of the species to disperse its seeds, the competition for light or nutrients,
pollinators.
Ordination of tree species at Kaieteur separated the 20 x 20 m quadrats in each plot primarily by spe-
cies composition. The quadrats were strongly correlated with some of the less dominant tree species such
as Eperua rubiginosa, Inga gracilifolia, Bombax eege DES SP. Hevea guianensis in KF1 and Pouteria
cuspidata, Clusia sp., Tapirira sp., Licania canella a KF2. Some species such as Hevea
guianensis that grows along more inundated soils get Bombax flaviflora of the dryer soils may help explain
the variation in the plots. Although the soils of the Potaro Plateau are largely composed of porous white
sand with very little nutrients, slope, accumulation of leaf litter, and hydrology can change over relatively
short distances (C. Kelloff, pers. obs.). Although ane by Eperua falcata and Chamaecrista adiantifolia
var. pteridophylla, the two plots at Kaieteur indicate differences in the forest community over very short dis-
tances (Fig. 5). This was not the case at Kwakwani or BCI where analyses indicated some overlap in species
composition between the quadrats of the plot pairs at each study site.
Although a forest type may be designated based on the dominant species, the forest is not without an
array of subdominant or even rare species that have an overall large effect on the floristic composition of
the forest. Such changes can occur over distance and time with changes in light (tree falls), seed dispersal,
soil composition or by turn-over (David & Richards 1934). An example of one such change is in the Kaburi
district of Guyana where the Eperua falcata forests were replaced over time by Dicymbe corymbosa Spruce ex
Benth. which expanded its dominance by self-pollarding, thus replacing mature trees with large clumps of
slender stems (Davis & Se E and eventually Gi out the other species. The forest at Kaieteur
could not be considered a t stand nor could it be considered stri ctly a a Wallaba (Eperua) forest.
As seen in plot 2 Chamaecrista adiantifolia var. pteridophylla became the dominate species in that area of the
forest. The main family that dominated the forest was the Caesalpiniodeae of the Leguminosae with over
300 stems. The subdominant families range from Lauraceae, Bombacaceae, Clusiaceae, and Fabiodeae.
CONCLUSION
Plots can be a powerful tool for providing long-term information on forest composition, diversity and struc-
tural change. They can then be used to assess changes in the forest over time, and the information gathered
from plots can be used to understand how other physical parameters may influence species composition
and distribution (Dallmeier & Comiskey 1998).
The two plots established at Kaieteur National Park were only a small sampling of the riparian forests
of the Potaro Plateau. The information gathered on the tree composition of just one area on the plateau dem-
onstrates the diversity and turnover in this forest. The Wallaba (Eperua) —mixed forest plot study at Kaieteur
had a larger number of trees per unit area over 10 cm DBH and represented almost twice the stems surveyed
in the Mora forests at Kwakwani, Guyana or in the lowlands of Barro Colorado Island, Panama. The plots at
Kaieteur were similar to the white sand forest studies by Whitton (1962) at Amatuk, Guyana and by Boubli
(2002) at Neblina, Brazil, with their large number of trees and dominance of the family Leguminosae. One
hypothesis presented by Torti and Coley (1999) suggested that legumes may be more successful in this
region because they have ectomycorrhizal fungi that are good scavengers for nutrients in the otherwise
nutrient poor soils and that these fungi suppress saprophytic fungi that are potentially detrimental to this
symbiosis. A study by ter Steege and Hammond (2001) suggested that seedlings were compensating for low
Kelloff, Kaieteur National Park, Guyana 541
light conditions by providing an internal energy source in the form of large cotyledons. Bulky endosperms
sustained larger seedlings and supported juvenile plants when light were insufficient. Although designated
as a Wallaba-mixed forest, Kaieteur did not have a SE dominant species such as Eschweilera dior dd
that was dominant in the lowland forest of Kwakwani. Studies have shown that Kaieteur |

ties of vegetation m Ge Beete inierence Statistical analyses al the plots at Kaieteur National
Park revealed d the species compo n between the plot pairs. This suggests subtle changes
in microhabitats and species dynamics of the subdominant tree taxa on the Potaro Plateau.
This study has shown that two 1 ha plots can adequately demonstrate how diverse tree species are in
one section of the forest; furthermore, it indicates that sampling was probably too small to capture all of the
different habitats represented at Kaieteur National Park. It still remains to be understood why the Caesal-
piniodeae and in particular the Eperua and Chamaecrista dominated the forest. Does this indicate favorable
ecological condition, the Janzen-Connell effects or can the Caesalpiniodeae legumes with its root nodules
thrive better is the nutrient poor soil of the Potaro Plateau? To answer these questions more studies need to
be done on the soils of the plateau.
Forests on white sand generally have a lower alpha-diversity than those on terra firme (ter Steege et
al. 2000a) but noted for their monodominance and high abundance of several tree families, such as the
Caesalpiniaceae. These forests also have trees that are locally abundant but globally restricted such as the
Greenheart, Chlorocardium rodiei (Rob. Schomb.) Rohwer, Richter, & van der Werff (Lauraceae), in central
Guyana. Development or poorly designed logging and mining practices can quickly lead to irreversible
damages to the forests and habitats, with eventual species loss or extinction. Analysis of the diversity and
the composition on the scale of plots can provide some of the best information needed define protected
areas in Guyana (ter Steege et al. 2000b; Kelloff 2003). It is on this scale that we can best understand plant
spatial distributions and how radically these can change over a relatively small geographic area.
Tue iamen. collected in the plot study at Kaieteur ES Park can be useful for monitoring
t assessment. This information, along
ral changes of the forest over time |
with the “Checklist of the Plant of Kaieteur National Park, Guyana” provides data on the plant taxa found
on the Potaro Plateau in the vicinity of Kaieteur National Park. In addition to minimizing habitat damage
due to industrial development, these data can be used to provide the framework for conservation efforts in
the park as well as for the development of ecotourism.

From 1931 to 1941, famed plant collector George B. Hinton (1882-1943) conducted extensive botanical
exploration, primarily in the southern Mexican states of Guerrero, México, and Michoacán. During this
time he made over 16,000 collections, and his specimens have served as the types of more than 360 spe-
cies (Hinton & Rzedowski 1975). On July 11, 1939 Hinton secured specimens in the Sierra de Coalcomán,
in southwest Michoacan of what is undoubtedly the most striking of all species of four-o'clocks (Mirabilis
L.). Despite the dist and showiness of the species, and the several duplicate specimens that were
distributed to major herbaria, the species remained “undiscovered” by taxonomists until Le Duc (1992)
described Mirabilis hintoniorum Le Duc over 50 years later. In the course of monographic work on Mirabi-
lis section Mirabilis, Le Duc came across four duplicates of Hinton’s collection, housed in herbaria at the
University of Texas (TEX), Conservatory and Botanical Garden of Geneva (G), Missouri Botanical Garden
(MO), and University of California, Berkeley (UC). When she published her monograph in 1995, Le Duc
had not encountered additionai collections of M. hintoniorum (Le Duc 1995). In this note, we provide a fuller
description and photographs of this remarkable species that had apparently not been recollected until we,
too, encountered plants in the Sierra de Coalcomán.
Although unremarkable in vegetative morphology, M. hintoniorum is unrivaled among the Heu 60
species in the genus by virtue of the form and color of the flowers. Le D
similar species on the basis of glabrous, few-flowered inflorescences and the ely shallow lobes and
orange color of the perianth. However, her observations, based only upon examination of few herbarium
specimens and Hinton's economical observations on the specimen labels, are not entirely accurate and fail
to convey the spectacular impression of the living plants. In particular, the inflorescences are hardly few-
flowered and the perianth scarcely orange.
On June 28, 2003 we collected Mirabilis hintoniorum for apparently the first time since Hinton encoun-
tered the species 64 years earlier. Had we been familiar with Hinton’s collection or Le Duc's description of
the species, we would have been wholly unprepared for the appearance of this seeming botanical fireworks
display (Figs. 1-3). The flowers, described by Hinton as simply “orange”, are in actuality pendent flames—

the perianth tube is bright red, grading into a vibrant yellow with red venation in the limb. However, these
features are lost with drying, and the flowers on both Hinton's and our herbarium collections are nearly
colorless. In contrast to the "few-flowered" inflorescences (Le Duc 1992, 1995) of Hinton's specimens, those
on the plants that we encountered comprise a many-flowered, pyrotechnic cascade. To Le Duc's otherwise
accurate description we can add that the plants are erect, bushy, perennial herbs reaching 1 m in height
with red stems. In addition to the aforementioned characteristics of the flowers, the stigmas are pink and
the anthers red.
Like Hinton, we encountered M. hintoniorum only in the Sierra de Coalcomán. Whereas the type local-
ity of Villa Victoria is along the Pacific Slope, our initial encounter took place approximately 55 kilometers
(airline) away, at the opposite (northeastern) end of the range within the Balsas Depression. We were brought
to an abrupt stop by the sight of M. hintoniorum while traveling along the unpaved road from Aguililla at the
foot of the mountains to the high-mountain logging town of Dos Aguas. As we approached the unknown
marvel, we were dumbstruck with the realization that we were gazing at a Mirabilis dramatically unlike any
that either of us had ever seen, the myriad cultivars of M. jalapa L. not excepted. Only a small patch of these
robust plants was found at this site, which we documented with several specimens (Fishbein and Steinmann
5113). Later the same day, we observed another small patch on the southwestern side of the range, between
Dos Aguas and Coalcomán along the road to Villa Victoria, from which no collections were made. We did
not observe the species anywhere else.
It is paradoxical that M. hintoniorum, arguably the showiest species in the genus, should have remained
so obscure, notwithstanding being a narrow endemic to the Sierra de Coalcomán. Two populations were

found along a moderately traveled, albeit rugged, road that has been traversed periodically by plant col-
lectors, including Rogers McVaugh. In fact, we made our collection at the type locality of Ipomoea fissifolia
(McPherson) Eckenw. It seems likely that the species is indeed endemic to the Sierra de Coalcomán and it
is quite likely rare. Furthermore, it possibly has a very brief flowering span in the early part of the rainy
season, and these factors may help to explain not only the few encounters by plant collectors but also the
absence of the “firecracker four-o’clock” from our gardens.

INTRODUCTION
Seasonally Dry Tropical Forests (SDTF) are one of the world’s most threatened ecosystems. Miles et al.
(2006) observed that ca. 97% of these dry forest remnants are at risk for biodiversity loss due to a number
of different anthropogenic Emel such as dira e On pret change, fire, or conversion into
cultivated areas. However, SDTF relatively little attention fro m vationists and ecologists
in comparison to humid forests (Pennington et al. 20060).
Little is presently known about the floristic diversity of neotropical SDTF although in recent years
there has been an increasing interest in this vegetation type (Gentry 1995; Giulietti et al. 2006; Pennington
et al. 20062). However, the growing knowledge of the SDTF flora has stimulated the formulation of various
hypotheses concerning the historical biogeography of this vegetation (Prado & Gibbs 1993; Pennington et
al. 2000, 2004; Prado 2000; Lavin et al. 2004; Queiroz 20062) and the geographical EEN of its com-
ponent species, and studies have indicated that SDTF are independent phy ts distributed
disjunctly through South and Central America (Pennington et al. 2000; Prado 2000).
According to the definition elaborated by Pennington et al. (2000), the neotropical SDTF comprehend
different physiognomies, and can include both forests as well as more open vegetation types where shrubs
predominate. Terrestrial bromeliads and succulent plants belonging to Cactaceae and Euphorbiaceae are

common in SDTF areas, as well as an ephemeral herbaceous tapparent only during the short rainy
season. Another important aspect characterizing SDTF is their maket; seasonal phenology of flowering
and fruiting, with many species demonstrating synchronous flowering at the transition between the dry
and the rainy seasons (Machado et al. 1997).
The Caatinga domain constitutes the largest and most isolated nucleus of the SDTF (Queiroz 20069).
It occupies ca. 800,000 Km? in the northeastern section of Brazil (Ab'Sáber 1974) with a semi-arid climate
mainly in the low altitude areas between extensive plateaus and/or mountain ranges (Prado 2003; Queiroz
2006a). Andrade-Lima (1981) noted that the vegetation of the Caatinga domain comprised different physi-
ognomies, including areas of open vegetation dominated by shrubs or areas with relatively tall forests. These
seasonally dry forests are commonly referred to as arboreal caatinga, dry forests, or deciduous forests, and
occur as highly fragmented areas throughout the semi-arid region of northeastern Brazil, principally from
Bahia State through northern Minas Gerais State. In spite of the fact that these dry tall forest areas are situ-
ated within the Caatinga domain (Rizzini 1979; Andrade-Lima 1981), different workers have indicated that
they may in fact be phytogeographically more related to the dry vegetation of the Atlantic Forest domain
(Oliveira-Filho & Fontes 2000; Amorim et al. 2005; Oliveira-Filho et al. 2005, 2006), or may represent dis-
junct areas of SDTF without any relationship to the humid areas of the Atlantic Coastal Forests (Pennington
et al. 2000; Prado 2000). The deciduous and semi- deciduous Desin of See and southeastern Brazil,
for example, have been Eeer to have a strong flori hip with the moister sites of Atlantic
Coastal Forest and therefore should not be treated as a type of dry tall forest included in the Caatinga domain
(Oliveira-Filho & Fontes 2000; Oliveira-Filho et al. 2005). However, Oliveira-Filho et al. (2006) have more
recently proposed a wider definition for SDTF that would treat these same deciduous and semi-deciduous
forests of the Atlantic Forest domain as another nuclei of SDTF.
As such, it is clear that there are still problems to be resolved concerning the nature of SDTF in eastern
South America. The delimitation of SDTF is complicated by the fact that Penington et al. (2000) and Prado
(2000) did not include humid forests in their analyses, while Oliveira-Filho et e (2006), on s ge nano,
included only a very limited sampling of Caatinga areas. Additionally, the | ledg
composition of many areas of SDTF in northeastern Brazil is still very incipient.
As such, the present study undertook a floristic survey of several fragments of seasonal dry forests in
the Serra do Orobó Mountains in central Bahia FS Sa uode GEN of these dry forests will be
discussed here in terms of the present und graphy of SDTF. Specifically, we intend
to demonstrate that the dry forest framents of the Bera do Orbe Mit s are floristically related to the
SDTF floras. To account this goal, we will treat the SDTF as a broader definition (sensu Oliveira-Filho et al.
2006) that encompasses the dry sites of the Atlantic Forest domain as a distinct nuclei from the Caatinga

Study Area
The Serra do Orobó mountain range is located within the municipalities of Ruy Barbosa and Itaberaba in
central Bahia State, Brazil (12°15’ — 12º25'S and 40°19’ — 40?30"W) (Fig. 1). The range occupies an area of
approximately 7,300 ha and has a maximum elevation of 1,014 m (BAHIA 2002). The region has a semi-
arid climate (SEI 1998), and although there are no systematic rainfall SE for this area, estimates of
precipitation in the region place the average annual rainfall at approximately 800 mm (SEI 1998). The aver-
age annual temperature is 26 ?C, with an bolas maximum af 33 °C, and an p minimum of 18 *C
(SEI 1998). The forest fragments examined have shallow soils that are sometimes covered by a significant
layer of leaf litter. These soils are classified in the main group “luvisoil” and present moderate to high pH
and nutrient levels (IBGE/EMBRAPA 2001). In addition, they are comparatively more fertile than those of
the nearby savannas.
The Serra do Orobó mountain range is located within the Caatinga domain of northeastern Brazil
(Velloso et al. 2002), and several vegetation types can be found there (Fig. 2) according to general altitudi-
nal gradients. A shrubby caatinga with palm trees is most common at lower altitudes, while forests occur

at higher altitudes (between 450 and 850 meters). Dry forest fragments and riparian forests are found on
the slopes at elevations between 450 and 700 meters. There is a more humid area near the summit on the
southern slope (between 700 and 850 meters) harboring a submontane humid forest. Above the forest zone,
and surrounding the mountain peaks up to the 900 meters, is a savanna-like vegetation with large popula-
tions of Vellozia furcata L.B.Sm. & Ayensu (Velloziaceae). Near the summit, the rock outcrops harbor campo
rupestre (rocky field) vegetation.
Although the Serra do Orobó has suffered strong anthropogenic alterations in 400 years of European
colonization, some forest fragments are still relatively well-preserved. These fragments have extremely high
conservation value as they represent some of the last intact fragments of dry forest in northeastern Brazil.
Additionally, many new species belonging to different groups, such as the fungi (Neojhonstonia minima,
Gusmáo & Grandi 2001), psychodid flies (Psychoda serraorobonensis, Bravo et al. 2006) have been described
from this area. Besides, some new species of plants from the campo rupestre vegetation were identified and
are in process of publication (Calliandra, Fabaceae-E.R.Souza & L.P.de Queiroz, pers. comm.; two new

In 2002, the forest remnants as well as the campo rupestre vegetation of the Serra do Orobó mountain
range were assigned the status of sustainable use protection areas in recognition of their importance to
conservation and to biodiversity research.
METHODS
A floristic survey was carried out from August 2004 to June 2006 in the best preserved sites of semidecidu-
ous, riparian, and submontane humid forest fragments. The vegetation classification used here for each for-
est fragment follows Veloso et al. (1991) and stresses the distinct physiognomies and ecological conditions
observed in each. It was studied 8 fragments of semideciduous forests (2.85 km2), 6 of riparian forests (0.37
km?) and one of submontane humid forest (0.07 km2).
During the course of the present study a total of 15 field trips were carried out, each lasting from three
to four days. Of all the 15 studied fragments, the submontane humid forest one was the unique where our
collect effort was lower due to its difficult access and because it was discovered only recently. All fertile
material of vascular plants was collected according to the standard methods described by Filgueiras et al.

many taxa were identified only to d genera (51 specimens, or 8.3% of he total collection) or family pu
(3 specimens, 0.596) due to their taxonomic difficulty.
The semideciduous forests demonstrated the greatest species richness (465 spp.), while 141 and 87
species were sampled in the riparian and in the submontane humid forests, respectively. Considering all
forest fragments together, the commonest life form was trees (182 species), followed by vines (138), herbs
(11D, shr E (109), See (45), and epiphytes (35). The most diverse families were Fabaceae Ge spe-
cies), Eupl (38 (24), Orchidaceae (24), Rubiaceae (24), Asteraceae (22), Bi
(19), Myrtaceae (18), RE (17), and Rutaceae (15), which together comprised 4896 of the total number
of species surveyed in the Serra do Orobó mountain range. Thirty-five families were represented by only a
single species. The most species-rich genera were Croton (11 species), Passiflora (8), Senna (8), Eugenia (7),
Myrcia (7), Solanum (7), Miconia (6), Bauhinia (5), and Senegalia (5).
Several species were identified by different specialists as pang new taxa (Fig. 3). These included:

DISCUSSION
Floristic diversity
The forest fragments of Serra do Orobó mountain range demonstrated a relatively higher number of spe-
cies in comparison to other Brazilian semideciduous forests, even comparing the arboreal component only
(Meira-Neto et al. 1989; Oliveira-Filho & Machado 1993; Soares-Filho 2000; Werneck et al. 2000; Jarenkow
& Waechter 2001; Moura & Sampaio 2001; Cielo-Filho & Santin 2002; Paula et al. 2002; Silva & Soares
2002; Nunes et al. 2003; Souza et al. 2003; Andrade & Rodal 2004; Toniato & Oliveira-Filho 2004; Rodal &
Nascimento 2006; Macedo 2007), or shrubby caatinga (Rodal et al 1998; Lemos & Rodal 2002; Pereira et al.
2002; Alcoforado-Filho et al. 2003; Nascimento et al. 2003; Andrade et al. 2004; Rocha et al. 2004), riparian
forests (Vilela et al. 1995; Funch 1997; Passos-Júnior 1999; Stradmann 2000; Ribeiro-Filho 2002; Lacerda
et al. 2005), or enclaves of humid forests within the caatinga (locally known as *brejo de altitude") (Tavares
et al. 2000; Rodal & Nascimento 2002; Melo & Rodal 2003; Agra et al. 2004; Barbosa et al. 2004).
The species richness encountered in the SUDAN humid forest (87 spp.) was surprisingly lower
than would normally be expected i in this forest | ] y in comparison with other studies (Mori 1989;
Lombardi & Goncalves 2000; Tavares et al. 2000; culo Sobrinho & Queiroz 2005; Amorim et al. 2005;
Neves 2005; Martini et al. 2007), and lower also that observed in the dry and riparian forest fragments of
the same mountain range. This may be due to the reduced size of the fragment examined, and/or to the
relatively low sampling effort in this area. As such, more field trips to the area may reveal the presence of
other species not yet recorded.
With minor variations, the ten most species-rich families in this survey were the same families identi-
fied as important in other SDTF sites, irrespective of the general aspects of the local climate, soil, and forest
physiognomy. Similarly, several of these families (usually Fabaceae, Euphorbiaceae, Apocynaceae, Bignoni-
aceae, SM AM and Rubiaceae) were important in sand dune areas of the middle Sáo Francisco river in
Brazil (Nascimento et al. 2003; Rocha et al. 2004), in caatinga areas on sandy soils (Araújo
et al. 1998; Rodal et al. 1998; Andrade et al. POE o a areas on I AN basement rocks
(Pereira et al. 2002; Alcoforado-Filho et al. 2003), astern and southern Brazil
(Jarenkow & Waechter 2001; Cielo-Filho & Santin 2002; Paula et al. 2002; Silva & Soares 2002; Toniato &
Oliveira-Filho 2004), riparian forests in the Chapada Diamantina of Bahia State (Funch 1997; Passos-Jünior
1999: Stradmann 2000; Ribeiro-Filho 2002), as well as in several neotropical SDTF (Pennington et al. 2000;
Bridgewater et al. 2003; Linares-Palomino et al. 2003). Fabaceae was the most species-rich family in the
Serra do Orobó mountain range as well as in the other sites referred to above. Schrire et al. (2005) presented
historical and biogeographical evidence supporting the hypothesis of a long term association between le-
gumes and dry forests. Amongst the vines, the families with the greatest numbers of species in the Serra
do Orobó (Apocynaceae, Bignoniaceae, Malpighiaceae, Fabaceae, and Sapindaceae) were also encountered
in other semideciduous forest fragments (Hora & Soares 2002; Udulutsch et al. 2004). These too similar
species richness at the family level encountered throughtout different physiognomies of dry vegetation in
558
Brazil as well as in the Central and northern South America may also be concerned for justifying that the
Serra do Orobó mountain range should be included into a broad definition of SDTF.
On the other hand, a more restrict evaluation comparing the most species-rich genera may be sugges-
tive to stress that within the different physiognomies of SDTF in eastern Brazil, the dry forest fragments of
the Serra do Orobó Mountains should be floristically related to the semideciduous forests of the Atlantic
Forest domain rather than to the dry shrub-arboreal vegetation of the Caatinga domain. For example, most
of the genera comprising the largest numbers of species identified in this survey, such as Croton, Passiflora,
Miconia, Myrcia, Eugenia, Solanum, and Bauhinia are better represented in several areas of semideciduous
forests (e.g. Soares-Filho 2000; Paula et al. 2002; Silva & Soares 2002; Nunes et al. 2003; Andrade & Rodal
2004; Amorim et al. 2005; Macedo 2007) than in shrub-arboreal caatinga areas (Araújo et al. 1998; Rodal
et al. 1998; Lemos & Rodal 2002; Pereira et al. 2002; Alcoforado-Filho et al. 2003; Cardoso & Queiroz,
unpublished data). Moreover, the paucity of Cactaceae species in the Serra do Orobó Mountains is another
evidence for lack of closer relationship with the Caatinga domain, where this family is usually abundant
(see for example Taylor & Zappi 2002; Rocha et al. 2004; Gomes et al. 2006).
Endemism
Among the 152 arboreal species surveyed in the dry forest fragments in the Serra do Orobó Mountains,
16 (see Append 1) are Loon ott Ee of the SDTF flora (Prado & Gibbs 1993). Besides, the
genera 4 il tia (Cactaceae), and Pterogyne (Leguminosae) surveyed here are endemic
to the SDTF as a whole (Prado 2000). In addition, another 14 species considered endemic to the caatinga
domain occur in the dry forest fragments of the Serra do Orobó Mountains or in other nearby areas, such
as Anemopaegma laeve (Bignoniaceae), Apodanthera glaziovii (Cucurbitaceae), Averrhoidium gardnerianum
(Sapindaceae), Capparis jacobinae (Brassicaceae), Heteranthia decipiens (Solanaceae), and Senna acuruensis
var. caatingae (Fabaceae) (Giulietti et al. 2002). This highlights that the Serra do Orobó Mountains may be
indeed related to the other remmants of seasonlly dry forests of the neotropics.
The presence of a considerable number of new species (ten) in the dry forest fragments in the Serra
do Orobó Mountains may be explained in term of the processes of metacommunities, a model recently put
forward for explaining the maintenance of diversity within SDTF (Lavin et al. 2004; Schrire et al. 2005).
These authors propose that the biogeography of the succulent biome (which includes neotropical SDTF)
can be better understood on a global scale by postulating metacommunities than by proposing historical
processes of speciation due to climatic changes or tectonic movements. According to this model, SDTF oc-
cur in isolated areas (i.e. much like islands isolated within the continental area), with each area functioning
like a local community that is linked to other areas through species exchange based on random dispersal
events. The more extreme environmental conditions in SDTF restrict colonization by species originating
in most other vegetation formations (Lavin et al. 2004), limiting the rate of immigration into a given local
community and resulting in floras that are locally endemic. These processes also result in genera with very
few species in local SDTF communities, in contrast with those observed in humid forests (Lavin 2006).
For example, the most diverse genera in SDTF (e.g. Senegalia, Croton, Machaerium, Mimosa, Senna, and Zan-
thoxylum) usually do not comprise more than ten species in any given forest area (see Werneck et al. 2000;
Nascimento et al. 2003; Rodal & Nascimento 2002; Bridgewater et al. 2003; Linares-Palomino et al. 2003;
Melo & Rodal 2003; Rodrigues et al. Pid Santos & Kinoshita 2003; Andrade & Rodal 2004; Lemos 2004;
Rocha et al. 2004; and this study), while 1 diverse genera in humid forests (e.g. Eugenia, Inga, Miconia,
Myrcia, Pouteria, Psychotria, and Solanum) can have from 15 to even 27 species of the same genus occurring
in the same locality (see Amorim et al. 2005; Neves 2005; Moreno et al. 2003; Lombardi & Gonçalves 2000;
Oliveira & Amaral 2004; Martini et al. 2007).
The dry forests of Brazil are distributed in a fragmented and isolated fashion (very much like islands),
which has led to the appearance of a significant number of endemic species. For example, 12 species en-
countered in this study had distributions limited to the forest fragments of the Serra do Orobó Mountains
and adjacent areas. As such, we suggest that the endemism observed in these forests can be explained (on
fe [| ) | ri = E | || | E A q A E Ba: Brazil 559
a regional level) by the processes of met ities, in much the same way as species exchange has been
proposed on a continent scale (Lavin et al. 2004; Lavin 2006; Schrire et al. 2005). In that context, the forest
vegetation of the Serra do Orobó Mountains as a whole could be viewed as a local community that is isolated
from other dry forest fragments found in eastern Brazil. Additionally, the recognition that this set of dry
forest fragments (together with the Serra do Orobó Mountains) is a regional metacommunity is supported
by the presence of disjunct species among the different areas—a pattern that has been similarly observed
at a continental scale among the different nuclei of SDTF (Pennington et al. 2006b; Lavin et al. 2004).
Cordia blanchetii, for example, has only been observed in the Serra do Orobó Mountains and in another dry
forest fragment in Jequié, Bahia State; Passiflora bahiensis has been recorded only in a few collections from
an urban forest fragment in Salvador, Bahia; Croton warmingii demonstrates a disjunct distribution within
other semi-deciduous forest fragments in a eieiei Gees jorgei and Senna acutisepala
(Fabaceae) are known in Bahia only from a few semid forest fragments in the southern part of that
state; and Margaritopsis carrascoana (Rubiaceae) occurs in isolated areas of dry vegetation from Ceará State
to northeastern Bahia.
Floristic relationships
Riparian forests.—These forests are closely associated with rivers and are widely distributed throughout
Brazil, principally in the central region of the country (Oliveira-Filho & Ratter 1995), although local abiotic
conditions may not always be adequate for the establishment of typical riparian forests (Rodrigues 2000).

encountered in the riparian forests occur only in this vegetation type. Many of the species occurring in the

distributed within the riparian forests of central Brazil, such as Copaifera langsdorffii, Hirtella glandulosa, Ta-
pirira guianensis, and the tree-fern Cyathea delgadii (Cyatl ) as noted by Oliveira-Filho & Ratter (1995).
These same authors postulated that these riparian forests could act as ecological corridors linking the two
principal nuclei of humid forests in South America (the Atlantic Coastal Forest and the Amazon Forest) due
to d dense EES EE all of the Cerrado Biome in central Brazil.

on the patterns of distribution of the arboreal species, adopted a similar circumscription, but considered
the caatinga and the seasonal dry forests of eastern Brazil as part of a greater phytogeographical unit of the
neotropics—the so common referred seasonally dry tropical forests (SDTF)—as distinct from the Atlantic
Coastal Forest. This phytogeographical unit would comprise a large variety of vegetation formations, from
tall forests in more humid areas to cactus scrub in the EE regions. This controversy can be clearly seen
in the great variety of names applied to these diff physiog ies, such as: in Gs EE dry

ments in the Serra do Orobó Mountains demonstrated that 106 species (46.596) also occur in areas of the

(Fabaceae), and Trichilia hirta Miaa A total p 56 ue 04%) v were common to areas sampled in the
Caatinga damain and included A
Senna spectabilis (Bibacedó) and Zizi joazeiro (RI ) (Giulietti etal. 2006). Of diesen n Bub.
nine of were considered as enden to ehe Castings domain (Giulietti et al. 2002). Additionally, if consider-
ing all the 318 endemic species to the Caatinga domain cited by Giulietti et al. (2002), another eight non
arboreal or shrub species occur in dry forest fragments of the Serra do Orobó Mountains or in other nearby
areas. However, these 17 species make up only 4.596 of the total endemic flora of the Caatinga domain,
suggesting that the dry forests of the Serra do Orobó Mountains might not be phytogeographically related
to the Caatinga domain, but rather are of Atlantic Forest vegetation. Therefore, these numbers reinforce the
hypothesis of Oliveira-Filho et al. (2006) that the semideciduous forests of eastern Brazil are floristically
more closely related to the Atlantic Forest domain than to the Caatinga domain.
These suggestions are further strengthened by comparisons made between the flora of the Serra do
Orobó Mountains and the Serra do Teimoso Reserve (a fragment of Atlantic Coastal Forest in southern Bahia
State). The Serra do Teimoso Mountains, like the Serra do Orobó Mountains, have dry vegetation at their
lower altitudes but more humid conditions exist at greater elevations, and the flora there is more closely
related to the Atlantic Forest domain than to the SDTF sensu Pennington et al. (2000) (Amorim et al. 2005).
Among the 252 arboreal species that occur in the Serra do Teimoso Mountains, 52 can also be found in the
Serra do Orobó Mountains, including Andira fraxinifolia (Fabaceae), Brasiliopuntia brasiliensis (Cactaceae),
Brosimum guianense (Moraceae), Cavanillesia arborea (Malvaceae), Caesalpinia pluviosa, Centrolobium tomen-
tosum, Goniorrhachis marginata (Fabaceae), in ae moa O Urera caracasana (Urticaceae),
ldin common include:
and Zantł | hoifolium (Rutaceae). E
Costus spiralis Coca Sinningia barata (Gesneriaceae), Coccoloba decimal (Polygonaceae), Faramea
hyacinthina (Rubiaceae), and Conchocarpus macrophyllus (Rutaceae). Additionally, species such as Croton
warmingii (Euphorbiaceae), Dimorphandra jorgei (Fabaceae), and Heteropterys macrostachya (Malpighiaceae)
demonstrate a disjunct distribution pattern between the Serra do Orobó Mountains and the semideciduous
forests within the Atlantic Forest domain.

INTRODUCTION
Coastal forests are an important component of the Atlantic Coastal Forest biome. These forests are distributed
along most of the eastern coast of Brazil. However, they have been subject to intense degradation within
this range, due mainly to their proximity to large urban centers.
Detailed information concerning the coastal vegetation of Rio de Janeiro State is relatively limited.
This study examines the coastal vegetation of the Morro Alto Mouráo region, including components of the
humid coastal forest and the near-shore (restinga) vegetation. The Morro Alto Mouráo is one of the highest
pou in Ee Serra da Tiririca Range did m). It is EE in southeastern Rio de Janeiro State between the
tal if EL ragments of one of the most highly threatened
f Niterói and Maricá. It still

The Serra da Tiririca Range is oriented almost perpendicular to the Atlantic coastline, which results
in contrasting climatic conditions on its two flanks. The western slopes are generally exposed to the humid
ocean winds. Intense rainfall is also common, principally due to cold fronts arriving from the southern
polar region. On the other hand the more sheltered eastern slopes lie in the rain shadow and receive less
and lighter rainfall.
The first historical references to the area date from the end of the 16th century when the Portuguese
crown awarded a ae land title esa to Duarte Martins Mourão. This title granted formal control of
the coastal lands | the Lagoa de Piratininga and Pedra de Inoã, in the current municipality of Maricá.
ce
Human use and occupation of this region is very intense. It was cultived with large numbers of small sugar
cane, coffee, and banana plantations, as well as citrus orchards up until the start of the 20th century (Grael
et al. 1995
Even though this region was highly disturbed (and is located near large urban centers as Niterói and
Maricá cities) the vegetation on the Morro Alto Mouráo is experiencing a gradual but natural regeneration.
Currently, plants with ornamental, medicinal, timber value and species of great scientific importance (rare
or endemic to the State of Rio de Janeiro and/or the Atlantic Coastal Forest) that are often little known to
botanists have been discovered.
Preliminary data from this study have been presented at scientific meetings and helped transform the
Serra da Tiririca Envi tal Protection Area into the more highly protected Serra da Tiririca State Park
(Rio de Janeiro State Law No.1901, of November 29, 1991).
This study presents the results of a floristic inventory undertaken in the area around the Morro Alto
Mouráo. This inventory examined the diversity and composition of the vascular plants within an area of
coastal forest. It is intended to be used to support conservation and degraded areas restoration efforts along
Rio de Janeiro State coast.
MATERIALS AND METHODS
Study Area
The Morro Alto Mouráo is located in the Serra da Tiririca Range, which covers a approximately 2700 hectares
near Pontas de TUAE and dere Gef 5804" S x id O! p uL (Fig. a The Morro Alto Mourão is
partofa pre-Cambrian (Niterói Massi | tl rn shore of the Guanabara
Bay. The peak has one ol ¡he highest elevations (369 m) in the Tiririca OUTING. together with Morro do
Elefante (or Falso Páo-de-Acúcar) (412 m) and Morro do Telégrafo (250 m) (Pontes 1987).
The ground is generally covered by leaf litter although there are also exposed rock areas. The sandy-
clay soil has a medium texture, is highly acidic (pH = 4.7-4.8) and has mid-range quantities of calcium
(3.5 me/100 mg), phosphorous (12 ppm) and magnesium (1.6 me/100 mg). The aluminum concentration is
high (1.0 me/100 mg), and the potassium concentration very high (> 135 ppm). The high acidity and large
quantities of aluminum and potassium found in the soils are probably the result of leaching and frequent
burning.
The western slopes of the Tiririca Range have a sub-humid climate (C2), with an A’ megathermic
temperature regime. The average annual temperature is 23.2° C, annual rainfall 1305 mm, annual evapo-
transpiration potential 1271 mm, real annual evapo-transpiration 1207 mm, annual water-deficit 64 mm
and annual excess 98 mm (Fig. 2). On the other hand, the eastern slopes have a sub-humid humid climate

is 23.2° C, annual rainfall 1207 mm, annual evapo-transpiration
potential 1223 mm, real al evapo-transpiration 1163 mm, annual water-deficit 60 mm and annual
excess 62 mm (Fig. 3). The greater rainfall and humidity encountered on the western slopes are due to the
direct influence of humid on-shore ocean winds.

Collections were undertaken on the Morro Alto Mourão, as well as on the Morro do Elefante and Pedra de
Itacoatiara, which have a similar vegetation cover. During the period from 1986 to 1988, collections were
less frequent. However, these were generally accompanied by certain plant group specialists or undertaken
especially to prepare schematic diagrams representing the phytophysiognomy of the vegetation.
All collected material was identified and registered at the herbaria of the Instituto de Pesquisas Jardim
Botânico do Rio de Janeiro (RB), the Universidade Santa Úrsula (RUSU) and GUA, HB, FFP (Orchidaceae).
The plant lists are presented in an appendix, with the family names in alphabetical order. The Angio-
sperm families are named according to Cronquist (1988). Those of the Pteridophytes are named according
to Kramer and Green (1990). The flowering and fruiting periods are derived from the specimens collected
in the area.

Climatic data for the Serra da Tiririca was obtained from the Niterói Weather Station (representing the
climatic conditions prevalent on the western slopes, directly exposed to humid winds and intense rainfall)
and from the Maricá Station (representing the climatic conditions prevalent on the eastern slopes that are
shielded from the humid winds and intense rainfall characteristic of the western slopes). The techniques
of Thornthwaite and Mather (1955) were employed to prepare local water balance diagrams, quantify the
available soil humidity (evapo-transpiration) and determine the degree (either deficiency or surplus) of the
water balance during the year based on the monthly rainfall data obtained from these stations.

RESULTS AND DISCUSSION
Taxonomic diversity
A total of 369 taxa were sampled within the study area. Seven of those were Pteridophytes (3 families), 295
were Dicotyledoneae (63 families) and 67 Monocotyledoneae (18 families) (Appendix 1).
Leguminosae (40 taxa), Euphorbiaceae (23), Rubiaceae (20), Myrtaceae (15), Solanaceae (16), Brome-
liaceae (12), Orchidaceae (12), Araceae (11) and Sapindaceae (11) represented the greatest taxa richness
These totaled 43% of the Angiosperms encountered.
Solanum (10 taxa), Rhipsalis (6), Machaerium, Philodendron, Anthurium and Trichilia (5 taxa each) were
the most representative genera.
Classifying these plants by habit, the largest diversity was observed among the herbs and sub-shrubs
which were regionally represented by 115 taxa. The trees comprised 96 taxa, followed by the shrubs, climb-
ers and epiphytes, with 92, 52, and 18 taxa, respectively (Appendix 1)
Comparisons of the plant species richness of Morro do Alto Mouráo with other forest areas within the
Serra do Mar Range in Rio de Janeiro State are shown in Table 1. A tendency towards reduced species rich-
ness can be seen within coastal forest areas near the city of Rio de Janeiro (Morro do Alto Mouráo, Horto/
JBRJ, and Morro das Andorinhas) in relation to humid forests in the Serra do Mar Range (Macaé de Cima,
Cairucu, and Tinguá). However, the high degree of local endemism of the coastal forests is very notable,
with 20 species restricted to only Rio de Janeiro State (Appendix 1). This same pattern of endemism was
reported by Lima (2000) and Sá (2006) who noted that most of the endemic species occurred in seasonal
forests.

The floristic diversity of the Morro Alto Mouráo flora was high in comparison with these other areas
of the Atlantic Coastal Forest (Horto/JBRJ and Morro das Andorinhas), even when allowing for the differ-
ent methodologies and sample sizes used in the different surveys. The significant floristic diversity of this
coastal mountainous region within the Serra "e Mar Range is Pea due to numerous factors, the most
important likely þei ificant local climat ity (due to t ition of the Serra
da Tiririca Range).

during the last tl turies) tl ] 11 pri imary forest f Iragments. According to Pontes (1987), the
Atlantic Coastal polest once red the entire region around the SES da Tiririca, but was subsequently
subjected to ext tation through logging and clearing. Only isolated sections of the original forest
remained in relatively inaccessible areas, such as Morro do Telégrafo and Morro Alto Mouráo.
Edaphic and climat t t have played important roles in the establishment of plant communi-
ties or large populations in the area, resulting in the mosaic of successional stages found there today.
Despite the often imprecise limits of distinction between them, three principal physiognomic forma-
tions are recognized in this study: arboreal, shrub-arboreal, and herbaceous.
Arboreal formation
Arboreal formations dominate the study area and they presumably occupied an even greater proportion of
the slopes in this region in earlier times. The topography is generally gentle and allows the accumulation
of organic and inorganic material (the latter formed by the gradual breakdown of the rock substrate) that
is necessary for soil formation and forest establishment. These arboreal formations now occupy the slopes
and depressions, resulting in the formation of deep and fertile soils.
There are two forest layers—the upper and lower canopies, determined principally by the height of the
component individuals (Fig. 5).
The upper canopy is closed and is composed of individuals that are generally between 12 and 25 m
tall (remnants of the original fores). Some emergents are to be found, with average heights between 25 and
30 m, such as Cariniana legalis, Anadenanthera colubrina, Pterogyne nitens, Schinus terebenthifolius, Gallesia
integrifolia and Coussapoa curranii.
The lower canopy is composed of individuals that are between 5 and 12 m tall. This layer is more open,
and the tree crowns being more widely spaced. Some representative species are: Piptadenia gonoacantha,

considered a distinct — in ens as they are very thinly distributed within the area. On the
other hand, there are dense populations of Schaueria calycotricha in shaded areas at the forest edge, near
rock outcrops with many weedy plants such as Petiveria alliacea, Sida rhombifolia, Oxalis barrelieri, Solanum

A single species of the hemi-parasite Struthanthus marginatus was encountered.
The herbaceous formation
This vegetation type is typically found on rock outcrops where plants grow directly on the rock surface
(rupicolous) or within thin sandy mips of Së near the rock outcrops (saxicolous). The plants at these sites
are exposed to extreme nditions due to their proximity to the ocean, including high levels
of solar radiation, strong, constant winds and high salinity (Fig. 7).

Cyrtopodium polyphyllum, Anthurium coriaceum, A. olfersianum, Philodendron speciosum, Coleocephalocereus
fluminensis, Rhipsalis cereoides, and Hylocereus setaceus are among the most frequent Angiosperm pioneer
species.
There are also small clumps of plants found in deeper soils areas, including individuals of Tibouchina
corymbosa, Tabebuia chrysotricha, and Stillingia dichotoma, in addition to the pioneer species.

Conservation
This area is significant because it contains a large number of species (20) endemic to the State of Rio de

(Klein 1990). Also relevant is the finding of species that are considered either rare and/or threatened, such
as Pterogyne nitens, Pouteria subsessilifolia (UCN 2004) and Astronium glaziovii. The latter species has only
a few collections registered in all of the Brazilian herbaria (Santin 1989). Among the plants encountered
that are threatened with extinction in the municipality of Rio de Janeiro are Inga congesta, Inga cordistipula,
and Lonchocarpus virgilioides (Lima 2000a). Additionally, Ficus enormis and Coleocephalocereus fluminensis
are considered to be threatened due to destruction of their habitat in the State of Rio de Janeiro (Duarte et
al. 2003; Calvente et al. 2005). Other rare species are Gomidesia sonderiana, which has rarely been found in
the Atlantic Coastal Forest (Nic Lughadha, pers. comm.); Alstroemeria caryophyllaea, which had only previ-
ously been encountered growing in the wild humid and shady areas in the States of Minas Gerais and Rio
de Janeiro (Assis 2004); Pleurothallis pardipes, recollected recently in Parque Municipal da Prainha, Rio de
Janeiro State (Pinheiro 1999).
The occurrence of these rare and/or threatened species, together with numerous cases of endemism,
illustrates the importance of conserving the Morro Alto Mouráo area. These (and other) species could po-
tentially be utilized as germplasm sources for seedlings production used to replant other fragments with a
similar floristic compositions in the Rio de Janeiro Atlantic Coastal sica
It is important to note that the Morro Alto Mourão area contains a bl | f j| ful

to humans or with significant direct economic potential (see Lopes 1992), including those with medicinal
(Lopes & Andreata 1989, 1990, 1991, 1992) and ornamental (Lopes et al. 2004) uses.
The economic potential of these plants, together with the proximity of the Morro Alto Mouráo area to
a large urban centre, complicates its preservation. Barros and Seone (1999) have proposed strategies for the
conservation of areas within the Serra da Tiririca State Park including monitoring to combat plant resources
extraction and fires, as well as controlling tourism.
CONCLUSIONS
The best represented plant families observed in the Morro Alto Mouráo area followed the same patterns
seen in other floristic inventories undertaken in the State of Rio de Janeiro (Marquete et al. 1992; Araujo &
Vilaca 1981; Lima € Guedes-Bruni 1997; Marques 1997; PMA/JBRJ 2002).
The phyto-physiognomic analysis of this area revealed a significant vegetation cover (predominantly
arboreal) in spite of both the historical and recent environmental aggression.
The eastern portion of the Guanabara Bay in the municipality of Niterói has only a few small forest
fragments HAM Seene the idis da Tipo. (PEEMA um im SS and the other data presented

INTRODUCCIÓN
El estado de Nuevo León no cuenta con un listado florístico actualizado, para el año de 1965, se regis-
traban un total de 1,296 EDO entre plantas nativas, cultivadas y adventicias, distribuidas en 657
géneros y 148 ee de a vasculares (Rojas-Mendoza 1965); otras estimaciones proponen cerca
e 2,400 ies d ı vascular (Alanis-Flores et al. 1996). De manera puntual, la vegetación acuática
o semiseudtira ha recibido poca o ninguna atención en los estudios florísticos, se conoce solamente un
estudio de la Presa Rodrigo Gómez y sus afluentes en el municipio de Santiago (Moreno 1984).
Para la familia Nymphaeaceae en Nuevo Eom solamente existen dais en la literatura de
Nymphaea odorata y N. mexicana, ambas son como especies Rojas Mendoza 1965),
sin que existan registros de herbario de estas especies hasta di See La única pe de la familia
Nymphaeaceae que ha sido publicada de manera formal con respaldo de un ejemplar herborizado es
N. ampla (Lot et al. 1986; Novelo y Bonilla 1999). De estados vecinos como Coahuila, se reporta solo N.
ampla (Villarreal-Quintanilla 2001; Villarreal-Quintanilla et al. 2006), mientras que para Tamaulipas
se reportan Nuphar luteum, Nymphaea ampla, N. elegans N. jamesoniana y N. amazonum (Lot et al. 1986;
Martínez y Novelo 1993; y Mora-Olivo y Villaseñor 2007), y en el estado de Texas, en Estados Unidos
de Norteamérica se reportan 4 especies de Nymphaea: N. ampla, N. mexicana, N. odorata y N. elegans,
además de Nuphar luteum subsp. macrophyllum (Correll y Johnston 1979; Wiersema y Hellquist 1997).
Cabe mencionar que para el caso particular del género Nuphar, ha existido una gran controversia en
J. Bot. Res. inst. Texas 2(1): 593 — 603. 2008
SM JO al of t tani ti Texas 2(
lo referente a la aplicación del epíteto específico, ya que N. luteum es de origen europeo, mientras que a
través de trabajos genéticos y moleculares las especies americanas han mostrado una separación de las
especies del viejo mundo, se aplica el nombre N. advena a los ejemplares reportados en trabajos recientes
(Wiersema y Hellquist 1997).
El objetivo del presente trabajo es d tar los registros de la familia Nympl en el estado
de Nuevo León, así como conocer el rango de distribución actual de las m presentes como una
contribución al conocimiento florístico.
METODOLOGÍA
Área de estudio
El estado de Nuevo León se localiza en la part te de México, entre los 98? 17' y 101? 07' de longitud
oeste, y los 23? 06' y 27? 50' de latitud norte. Limita al norte con los Estados Unidos de América y los
estados de Coahuila y Tamaulipas; hacia el poniente limita con los estados de Coahuila, San Luís Potosí
y Zacatecas, mientras que hacia el sur colinda con San Luis Potosí y Tamaulipas, con este ultimo también
comparte la totalidad de su límite oriental (Fig. 1).Su superficie es de 64, 081.94 km”, las elevaciones van
desde los 200 a los 3,700 m sobre el nivel del mar. Se presentan porciones importantes de tres regiones
fisiográficas de México, la Sierra Madre Oriental, la Gran Llanura de Norteamérica y la Planicie Costera
del Golfo (Alanís-Flores et al. 1996). Predominan los climas semisecos extremosos, la precipitación
pluvial es variable, el promedio general va desde los 300 a los 600 mm de precipitación anual. Los
climas secos y semisecos se distribuyen principalmente de la región nororiental y en la región suroc-
cidental, ambas áreas están separadas por la Sierra Madre Oriental, siento en esta última donde además
se presentan climas, semicálidos, templados y semifrios en la zona centro y sur de la entidad (INEGI
1986). La vegetación se compone principalmente de matorrales desérticos y semidesérticos de diversa
composición florística, en la región de la Sierra Madre se presentan bosques con distintas asociaciones
de encinos, pinos, y coníferas. En menor grado se presentan sucesiones edafológicas como vegetación
gypsófila o vegetación halófita; la vegetación acuática solamente se encuentra registrada como bosque
de galería en algunas corrientes de agua permanentes del estado (Treviño-Garza et al. 2001). Si bien
existen en Nuevo León áreas con hábitats de tipo lótico, como escurrimientos temporales en
el área de la Sierra Madre Oriental y vegetación riparia, son pocos los ríos que actualmente mantienen
el flujo de SEH a lo largo del año; por otra pue los ecosistemas lénticos que son el hábitat potencial
para la familia Nymy , Son sumamente escasos , algunos han desaparecido en los municipios de
Galeana y mene We por el uso desmedido del recuso hídrico en las actividades agropecuarias, otros
como en el caso del Cañón de la Huasteca en el municipio de Santa Catarina, han sido canalizados para
el abastecimiento de la zona metropolitana de Monterrey, dejando en la actualidad solo unos cuantos
sitios restantes en el estado para el desarrollo de comunidades de vegetación acuática y semiacuática.
Métodos
Primeramente se realizó una revisión y consulta bibliográfi la básqueda de registros de la familia
Nymphaeaceae en Nuevo León, además de conte en las bases de datos de ee E herbarios:
TEX, LL, UNL, MO, NY y el herbario de George B. Hinton para la búsqueda de
de la familia.
Se realizó trabajo de campo en las diversas localidades q ]taron de la búsqueda de ejemplares
de herbario para corroborar la presencia de las especies en la actualidad, en total se realizaron visitas a
17 localidades con hábitat potencial en di municipios de Nuevo León para documentar los sitos de
distribución de las especies (Tabla 1). Las diagnosis de la familia, géneros y especies, así como la identi-
ficación de los ejemplares colectados están basadas en Zomlefer 1994; Novelo y Bonilla 1999; Calderón
y Rzedowski 2001; Correll y Johnston 1979; Wiersema y Hellquist 1997.
El material colectado, fue herborizado y depositado en el herbario de la Facultad de Ciencias

Chiang, 1986 para el montaje y herborización de ejemplares botánicos.
RESULTADOS
En el estado la familia está representada por 2 géneros (Nymphaea y Nuphar) y 4 especies (Nymphaea
ampla, N. elegans, N. mexicana y Nuphar advena), las cuales se distribuyen en 4 municipios en la Planicie
Costera del Golfo y los límites con la Sierra Madre Oriental (Figs. 1-3).
Los registros de herbario muestran que se han extirpado diversas poblaciones, Nuphar advena ha
desparecido del municipio de Paras, mientas que Nymphaea ampla se ha eliminado de diversos hábitats
en los municipios de Fa Lampazos de Naranjo y Apodaca (Tabla 1).

Familia con una amplia distribución mundial, desde las regiones frías y templadas en el hemisferio
norte hasta el trópico, habitando cuerpos lénticos de agua dulce; se incluyen en Ja familia 6 géneros con
alrededor de entre 50 y 66 especies. En México se presentan 2 géneros con entre 11 y 12 especies. En el
pasado se incluían en esta familia a los miembros de Cabombaceae y Nelumbonaceae, las cuales ahora
se encuentra segregadas gracias a estudios moleculares.

Se distribuye en América, Europa y Asia; un genero complicado desde el punto de vista taxonómico,
muchas veces se presentan híbridos y rasgos intermedios entre poblaciones; se reconocen entre 10 y
12 especies, las cuales a algunas veces se tratan como subespecies, en México ocurren l o 2 especies
dependiendo del sistema de clasificación que se adopte. En Nuevo León ocurre solo una especie.

Plantas herbáceas acuáticas, enraizadas, rizomas de entre 5 y 10 cm. de diámetro; hojas comúnmente
emergiendo del agua, pecíolo terado, o adaxialmente algo aplanado, laminas adaxial y abaxialmente de
color verde, ampliamente ovadas hasta casi orbiculares, de 1 a 2 veces más larga que ancha, de hasta
40 cm de largo por hasta 30 cm de ancho, seno de la lámina de 1/3 a Y de la longitud de la nervadura
central, los lóbulos se sobreponen o son divergentes, a menudo formando un ángulo de 90? o mayor, la
superficie abaxial de la lámina es glabra a escasamente pubescente; flores de hasta 5 cm de diámetro;
sépalos comúnmente 6, abaxialmente de color verde y de color amarillo en la superficie adaxial, a veces
teñidos de rojo hacia la base, pétalos oblongos y gruesos; anteras de 3 a 7 mm, más largas que los fila-
mentos, disco estigmático verde, algunas veces rojizo, de 13 a 25 mm de diámetro, entero o crenado,
rayos estigmáticos de 9 a 23, lineares a lanceolados, terminando de 1 a 3 mm desde el margen del disco;
fruto verde, ovoide, con costillas poco prominentes algunas veces, algo constreñido por debajo del disco
estigmático, semillas de 3 a 6 mm de largo.
Se ha registrado la desaparición de la población del municipio de Paras, esto es atribuible a la dese-
cación de los cuerpos de agua en algunas temporadas; las poblaciones del municipio de Sabinas Hidalgo
son abundantes, sin embargo se le considera como una especie problemática por su rápido crecimiento
y puede llegar a cubrir rápidamente grandes extensiones de cuerpos de agua someros

DISCUSIÓN
Se identifican dos situaciones preocupantes, en primera instancia, el presente estudio pone de mani-
fiesto la reducción en la distribución geográfica de las especies de flora asociadas a cuerpos de agua, por
mencionar un ejemplo, N. ampla, ha d ido de 3 localidades en las cuales estaba documentada con
ejemplares colectados entre los años de 1938 y Ro esta situación es Ao en ud parte a la dese-
ción intenrinnal] de q cuerpo sae agua ;€ uso ] volú C gua F superficial
para riego y consumo humano (Recdowaki 1978), pe manera stet a estos factores, el uso recreativo
en algunas zonas ha sido determinante en la modificación del hábitat y la desaparición de especies; así
de un total de 17 localidades visitadas en el estado, solamente 4 albergan poblaciones de esta familia.
Una EES situación de E es a poca representación de esta en los herbarios consultados,
esto se pone te 4 ejemplares herborizados y 1 una especie reportada
en la literatura, aún más se contabilizan un total de 11 especies de angiospermas acuáticas estrictas
registradas para Nuevo León (Lot et al. 1998), siendo los miembros de esta familia, especies llamativas
y conspicuas por sus características fisonómicas, es difícil oca el poco interés por feo e esta
familia en las colecciones botánicas, aún asi, el pres arroja que l I
(Nymphaea elegans y N. mexicana) se presentan como nuevos registros para Nuevo bein:
En base a las colectas históricas, así como lo observado en las distintas localidades visitadas, en
donde se ha observado un alto impacto por actividades del hombre e incluso la total desaparición del
hábitat en algunas localidades, se estimaría que en un lapso de 10 años las especies aquí reportadas
puedan desaparecer del hábitat restante en el estado de Nuevo León, esta EE ha sido denotada
en otros estudios, tales como el de Novelo y Bonilla (1999) qui a Nymphaea ampla como "rara
en la región de estudio y por lo tanto vulnerable a la extinción," esto a pesar de ser una de las especies
con mayor distribución en México.

INTRODUCCIÓN
México es un país megadiverso dada su ubicación dentro de las regiones Neártica y Neotropical (Rzedowski
1978). Su flora nativa oscila entre 75 órdenes, 304 familias, 2,804 géneros y 22,351 especies, en los 200
millones de ha de superficie que abarca el país (Villaseñor 2004). Este mismo autor, utilizó métodos no pa-
ramétricos para estimar a EEN total del país, así se añadirían a estas cifras más de 6,500 especies,
por lo q
r en el orden de las 29,000 especies. Con estas cifras la República
Mexicana ocupa el o lugar entre los países con mayor riqueza florística del mundo (Sarukhán & Dirzo
2001). Sin embargo, E conocimiento de su fitodiversidad es todavía incompleto aired i
Lazonat ] subhümeda del t
mexicano cubre la mayor parte d del
país, con una — cie de ca. 33 millones de ha, que corresponde al 1596 d la superficie nacional (Toledo
& Ordoñez 1998). Esta zona se caracteriza por contener elementos holárticos, predominantemente en el
estrato arbóreo, mientras que los estratos arbustivo y herbáceo son neotropicales, formando un complejo
mosaico con los elementos autóctonos (Rzedowski 1978). Los principales tipos de vegetación en esta región
son los bosques de coníferas, bosque mixto y bosque de Quercus, mientras que el bosque mesófilo de mon-
tafia, el cual pertenece a la zona templada hümeda, representa una transición entre las regiones tropicales
y templadas (Rzedowski 1970). La flora de estos bosques de coníferas junto con la del bosque de Quercus
representan cerca de 2596 del total de la flora vascular de México (ca. 7,000 especies), de las cuales ca. 4,900
especies son endémicas (Rzedowski 1991).

La cuenca del Valle de México (CVM) contiene bosques de filiación templada en las que se desarrollan
cerca del 2% de las plantas del planeta (Calderón de Rzedowski & Rzedowski 2001). En esta cuenca endo-
rreica de origen volcánico con una extensión ca. de 7,500 km?, se ubica el Distrito Federal que, a pesar de
contener una de las ciudades más grandes del mundo, todavía cuenta con importantes áreas con vegetación
natural, las cuales representan el 58% de su territorio (Corenader 2006).
Dentro del Distrito Federal, se encuentra la delegación política Magdalena Contreras, la cual ocupa
el 9? sitio en extensión territorial, y más del 70% de su superficie corresponde a la categoría de suelo de
conservación. Sin embargo, el conocimiento sobre la fitodiversidad es limitado.
En la Delegación Magdalena Contreras se localiza el río Magdalena, el cual representa uno de los cuer-
pos de agua más importantes del Distrito Federal (Delegación la Magdalena Contreras, 2006). El tipo de
suelo y la cobertura forestal que ésta presenta, promueve la infiltración del agua de lluvia hacia los mantos
acuíferos de la CVM (Mazari 2000), por lo que un excedente hídrico de 10% podría ser aprovechado en
la zona urbana (Jujnovsky 2006). Al río Magdalena se le reconoce como un río vivo del Distrito Federal y
existe un interés reciente por parte de las autoridades de la ciudad en manejar integralmente la cuenca.
Debido a que estos bosques enfrentan una gran presión antrópica, es importante conocer la fitodiversi-
bd deg estas comunidades boscosas, con la finalidad de evaluar su estado de conservación y poder proponer
Este trabajo presenta eli tario inicial de la fitodiversidad de plantas
vasculares SS la cuenca del río Magdalena (CRM) y su zona de influencia.
Antecedentes.—Algunos de los autores que han realizado estudios Pus de E y vegetación en la
CRM y zonas adyacentes son: Rzedowski (1954) hizo un análisis de la li n el matorral xerófilo
del pedregal de San Ángel, Madrigal (1967), estudió el bosque de Abies religiosa en » zonas montañosas
de la CVM, Rzedowski (1970), realizó una descripción para el bosque mesófilo de montaña en la CVM,
encontrando algunos fragmentos dentro de la CRM, Velázquez y Cleef (1993), definieron las asociaciones
vegetales en los volcanes Tláloc y Pelado, y Nieto de Pascual (1995) describió la estructura y composición
de los bosques de Abies religiosa en la CRM. En el 2001, Calderón de Rzedowski y Rzedowski actualizaron
la información sobre la flora del valle de México, estimada en alrededor de 2500 especies, la cual ha sido
base para estudios recientes como los de Ávila-Akerberg (2002) y Nava (2003), quienes presentan datos de
cobertura de las especies registradas por comunidad vegetal, así como su relación con diversas variables
ambientales en la CRM.
Área de estudio.—Localización física.— La cuenca del rio Magdalena (CRM) se ubica dentro de la Cordil-
lera Volcánica Transmexicana (CVT), en la provincia florística de las Serranías Meridionales, dentro de la
región Mesoamericana de Montaña (Rzedowski 1978). Esta área forma parte de la CVM en la vertiente oc-
cidental de la sierra de las Cruces con un intervalo altitudinal de los 2,530 alos 3,870 msnm y una extensión
aproximada de 3,000 ha (Fig. 1).
Relieve.—Los bosques de la CRM se desarrollan en un relieve montañoso, dada su ubicación dentro de
la CVT. El modelado del pu se debe principalmente a la acción erosiva hídrica y a los procesos fisico-
químicos, siendo el desgas a corriente del río Magdalena el que ha ido formando un valle intermontano
longitudinal joven TOME 2000).
Geología.—El área de estudio presenta diferentes etapas en su evolución relacionada directamente con
el origen de la CVM (Ontiveros 1980). Esta zona está formada por material ígneo extrusivo, producto de
manifestaciones volcánicas del Terciario y Cuaternario (Álvarez 2000). El basamento de la CRM, está con-
stituido por macizos de la sierra de las Cruces, de principios del Terciario, alcanzando el Terciario Superior.
Esta sierra es uno de los principales focos de actividad del CVT que se formó como consecuencia de una
serie de emisiones pacíficas de lavas ácidas. Formaciones KL i dan lugar alos cerros de San Miguel y
la Palma (Cervantes 1969). La CRM, es el resultado de un afallamiento en bloques que deja bancos abruptos
de forma regular en donde el río se encajona en márgenes estrechos (Álvarez 2000).
Hidrología.—El río Magdalena tiene un cauce de una longitud total de 21,600 m, de los cuales 15,200
m recorren los bosques de la cuenca del río Magdalena (Ávila-Akerberg 2004). Posteriormente, el río entra a

zona urbana hasta llegar a la presa Anzaldo en donde el río es entubado y dirigido hacia el río Churubusco.
Las aguas continúan su recorrido para finalmente salir de la CVM a través de los túneles artificiales de
Tequisquiac y llegar a la cuenca del río Tula (Álvarez 2000). Las características hidrológicas de la CRM se
deben a factores como la altitud y la influencia de las masas marítimas, tanto del Golfo como del Pacífico,
que favorecen las condiciones de humedad. Así mismo, la estructura geológica de la sierra de las Cruces y
las precipitaciones han permitido que la zona mantenga una infiltración constante, generando una fuente
de almacenamiento de agua (Ontiveros 1980).
Suelo.—Fl suelo en la CRM es resultado de una formación de material ígneo extrusivo, producto de
manifestaciones volcánicas del Terciario y Cuaternario, predominando las Andesitas y Dacitas (Ontiveros
1980). Los suelos son, en su mayoría, Andosoles del tipo húmico, mólico, ócrico con mezcla de Litosoles,
con textura franco, migajón arcilloso y arenoso. Los suelos con textura franca se encuentran distribuidos en
toda la región. En las partes altas, el pH es más ácido y el contenido de materia orgánica es mayor (Jujnovsky
2006).
Clima.—En la parte baja de la CRM, entre los 2530 y 2800 msnm, se presenta el subtipo climático C (w;)
(w) (b) i'g (Koppen modificado por Garcia 1987); templado subhúmedo, el más húmedo de los subhúmedos
con régimen de lluvias de verano y porcentaje de lluvia invernal menor al 596. El verano es fresco y largo, la
temperatura media anual oscila entre 12 y 18? C, la temperatura del mes más frío entre -3 y 18° C y la del
mes más caliente entre 6.5 y 22? C, con poca oscilación térmica y marcha de la temperatura tipo Ganges.
En la parte alta, de los 2800 a los 3500 msnm el clima es Cb’ (wj) (w) (b” i g, difiriendo del anterior por
tener una temperatura media anual entre 5 y 12? C con oscilación térmica menor a 5? C, es decir, isotermal
(García 1987).
Los porcentajes de lluvia altos se registran para el período de mayo a octubre, siendo el mes de julio
cuando se alcanza una precipitación que supera los 250 mm. Las mayores temperaturas acontecen desde
marzo hasta octubre, siendo el mes de mayo el más caluroso y enero el más frío (Álvarez 2000).

MÉTODO
La recolecta de ej ] f lizada durante las múltiples visitas a la zona de estudio entre 2004 y 2006,
en 128 sitios de: muestreo, dentro de los diferentes tipos de vegetación de la CRM y zonas adyacentes. En
estos sitios se registraron datos ambientales de altitud, pendiente, orientación y suelo desnudo.
Los ejemplares fueron herborizados, etiquetados y determinados a nivel de especie con ayuda de claves
taxonómicas especializadas para la zona (Beetle 1983 y 1987; Calderón de Rzedowski & Rzedowski 2001,
Espinosa & Sarukhán 1997). Para las determinaciones botánicas se siguió la clasificación propuesta por

Soen mobot3.org). El material colectado fue depositado en la colección del Herbario FCME (Facultad de
Ciencias, UNAM).
Se identificaron las especies arvenses y ruderales consultando los trabajos de Espinosa & Sarukhán
(1997) y Calderón de Rzedowski & Rzedowski (2001). Se realizó un análisis de coeficiente de relación entre
las especies y géneros de la familia Asteraceae contra el total de las especies para comprobar la intensidad
de muestreo (Rzedowski 1991).
RESULIADOS
El estudio registró un total de 87 familias con 251 géneros y 487 especies en la lista florística (Apéndice 1).
Las familias más importantes en cuanto al número de especies son: Asteraceae 21%, Poaceae 4.9%, Lami-
aceae 4.7%, Caryophyllaceae 4.3, Rosaceae 3.7% y Brassicaceae 3.5% (Tabla 1), mientras que, las familias
con mayor número de géneros son: Asteraceae 18.2%, Poaceae 5.7%, Brassicaceae 5.3%, Fabaceae 4.0%,
Rosaceae 4.0% y Lamiaceae 2.8%. Los géneros con más especies son Salvia (13), Ageratina (10), Pinus (8),
Quercus (7), y Roldana y Senecio con (6).
En cuanto a las formas de crecimiento (por especie, Fig. 2) las herbáceas son las más abundantes (365
p seguido de las arbóreas (49), arbustivas GE rasantes (20), lea (5) y epífitas (4).

De la lista florística resultante (487 especies), se registraron 10 especies en alguna categoría de riesgo
de acuerdo a la Norma Oficial Mexicana 059-SEMARNAT-2001 (DOF, 2002), de las cuales 3 son endémicas
a México: Furcraea bedinghausii, Acer negundo var. mexicanum y Dahlia scapigera (Tabla 2). Otras especies,
por el contrario, se ven favorecidas por condiciones de perturbación por lo que es comün encontrarlas en
cultivos IN O Hein a a orilla de caminos (ruderales). Dentro de estas especies se encuentran: Acaena
elongata, Achill iolaris, Cerastium nutans, C. vulcanicum, Drymaria laxiflora, Erigeron
galeottii, Gerni seemannii, Tr ger Senecio cinerarioides y Sigesbeckia jorullensis, entre otras. El
total de las especies arvenses y/o ruderales fue de 69.
El valor de coeficiente especies-géneros (e/g) para la familia Asteraceae fue de 2.3, en tanto que el
coeficiente e/g para el total de la flora registrada en este estudio fue de 1.94, dando una diferencia de 0.36.

vado por Rzedowski (1978) y Cornejo-Tenorio et al. (2003) para la generalidad de los bosques templados de
México. Sin embargo, considerando la cobertura, el estrato arbustivo es el dominante, lo que puede ser un
indicador del deterioro de la zona. Este se explica por la deforestación, lo que genera claros en el dosel del
estrato arbóreo permitiendo o estimulando el crecimiento de los arbustos.
El endemismo en las EE de la CRM, presenta proporciones similares a las evaluaciones previas de la
flora de las regiones t de México, ya que Rzedowski (1991) estima que la proporción de especies
endémicas del país para los bosques de coníferas y de encino equivale al 70% y para el bosque mesófilo de
montaña, a 30%.
La familia Asteraceae, con 102 especies, es la mejor representada en la cuenca, P wi: en menor
proporción por Poaceae, Lamiaceae, Rosaceae, Fabaceae y Brassicaceae. Este patrón
ha sido encontrado también en otros trabajos realizados en tipos de DECH similares a los de la cuenca,
como es el caso del Parque Nacional Lagunas de Zempoala (Bonilla y Viana-Lases, 1997), en el volcán Po-
pocatépetl (Almeida-Leñero et al. 1997), el área de San Juan Nuevo Paranguricutiro (Medina-García et al.
2000) y la Reserva de la Biosfera de la Mariposa Monarca (Cornejo-Tenorio et al. 2003). Se ha visto que en
las latitudes donde la familia de las compuestas juega un papel importante, el cociente entre el número de
especies y géneros de compuestas se aproxima al mismo valor para toda la flora fanerogámica de un área.
Para la cuenca del río Magdalena se encontró que este cociente es de 2.3, y si se multiplica por el número
total de géneros (250) nos da 579 especies, número relativamente mayor al total de especies en el área de
estudio (487 spp). Esto indica que algunas de estas especies han desaparecido, que hay sinonimias, incon-
sistencias en los listados o que aún es insuficiente el esfuerzo de colecta. Sin embargo, al revisar los trabajos
realizados por autores como Reiche (1914), Madrigal (1967), Sánchez (1969), Rzedowski (1970), Nieto de
Pascual (1995) y Calderón de Rzedowski y Rzedowski (2001), se cuantificó un mayor número de especies
en la zona, que las registradas en este estudio. Por lo tanto, es fundamental continuar con el monitoreo de
la flora en la zona, sirviendo éste como Aa paras medir el pato de conservación.
Los resultados que se EE an en n el papel fund I que gesemipena la CRM
como área de 1 de la j| , no sólo por la riqueza florística sino también por la cantidad
de especies endémicas (ca. 85 especies) y en alguna categoría de EE La Delegación Magdalena Con-
treras presenta más del 78% de su territorio como suelo de co 5n, por lo tanto la riqueza de especies
en esa superficie es relevante si consideramos que por Seuples en el caso de plantas, se alberga poco mas
del 25% de la diversidad floristica que existe en el valle de México o el 2.2% de la riqueza total del pais. Si
ademas se toma en cuenta la presencia en la zona de uno de los ultimos rios vivos en el Distrito Federal y
la presencia de elementos del bosque mesófilo de montaña casi desaparecidos de la CVM, es fundamental
priorizar el cuidado y recuperación de esta cuenca.
Se espera que la información florística proporcionada por la presente contribución pueda ser útil en la
elaboración del pan de so EE ER la zona, que representa: un SE gp esta AA y que
I a ala ciudad
A partir de esta información, es importante fomentar estudios similares en zonas eer abordando
juega un papel 1
además otros aspectos biológicos, sociales, económicos y políticos.

ABSTRACT
Praxelis clematidea (Asteraceae) is a new genus and species for North America. Praxelis is compared with similar species, and their
diagnostic characters are discussed.
RESUMEN
P lis cl tidea (A ) es un gé i América del Norte. Se compara Pra» elis con i i , Y se
discuten sus caracteres diagnósticos.
Field work in central Florida by the second author has led to the discovery ER a plant species new to North
America, Praxelis clematidea (Griseb.) R.M. King & H. Rob. (Fig. 1). The sp to Árgentina, Bolivia,
Paraguay, and Brazil (King & Robinson 1987). It is also erroneously reported from Venezia Waterhotise
et al. 2003). It has been naturalized in Australia, China, and Hong Kong (Corlett & Shaw 1995; Veldkamp
1999; Waterhouse 2003). There are 13 additional species of Praxelis Cass., all restricted to South America,
none of which are known as exotics elsewhere (King & Robinson 1987). A more complete description of P.
clematidea is available on-line (U.S. Forest Service 2007), as are photos (Waterhouse et al. 2003), including
comparison with the similar Ageratum houstonianum Mill. (Pollock et al. 2004).

Praxelis clematidea: herb to suffrut t shrub to ca. 1.3 m tall; stems soft pubescent (densely villous to
hirsute, especially above); petioles usually very short, well less than 1/4 the blade length (except on the
lowest leaves which may have petioles up to ca. 1/3 or more the blade length; these leaves are often gone by
the time the plant is in fruit); blades ovate, rounded to cuneately narrowing at the base, generally about half
(or more) as wide as long; margins irregularly toothed, i.e., some teeth nearly dentate, others more sharply
serrate, with size variation even on same leaf; heads cylindrical-campanulate, clearly longer than wide (ca.
3-4 mm wide, 6—8 mm tall), in lax to dense clusters; phyllaries about 1 mm wide, flat, densely imbricate,
although deciduous in fruit, with conspicuous dark striations from the veins.
A visit to the region on 17 July 2007 discovered hundreds of individuals of Praxelis at several scattered
localities, all disturbed roadsides. This local delen in so many different spots, in conjunction with the
original collection in a relatively remote and i area, suggests that Praxelis has been in Florida for
some time and has been spreading. The site where the species was first bcn in July oe is an open old
field dominated by exotics [Rhynchelytrum repens (Willd.) C.E. Hubb.; Ricl } es; on edges,
Urena lobata L.] and ‘weedy’ natives [Cenchrus spinifex Cav., Heterbtheca subaxillaris (Lam.) Britton & Rusby,
Bidens alba (L.) DC.]. The site is a dry, well-drained sandy upland that was once a citrus grove. Although
there are no indisputable indicators of the original vegetation, t that it may have been
sandhill o e.g., Soma erecta L., Croton EEN L., Galactia elliotti Nutt., Opuntia humifusa

Moni (L. Greene ex Parier & Britton and Verbesina virginica L. The area is now mostly surrounded
by dry pine woods that appear secondary, with a remnant swampy baygall nearby to the southwest. The
site has about 200 Florida gopher tortoises (Gopherus polyphemus) and a density of about 29.1 tortoises/ha,
which is very dense for gopher tortoise populations. Praxelis was completely absent on a follow-up trip on
5 November 2006, at which time the site was also seen to be heavily disturbed by hog rooting (Sus scrofa).
One small patch was rediscovered in the same area during a follow-up visit on 23 August 2007, making it
clear that the species is established at the site. A follow-up trip on 8 March 2008 to the Lake Hancock Road
site found that, as part of a road construction project, the population had been nearly eradicated (although
achenes are doubtless still persisting in the area); only one plant was seen (and it was in flower), with the
remaining area covered in fresh sod. This did demonstrate that at least some individuals of Praxelis over-
winter as above-ground perennials, flowering year-round (or nearly).
Eupatorieae are distinguished by the combination of discoid heads, anther bases non-tailed (obtuse,
rounded, or truncate), styles usually more or less filiform, style-branch appendages usually terete to clavate,
and leaves usually opposite (FNAEC 2006a). Praxelis keys to either mea ue imd or Chromo-
laena DC. in FNAEC (2006b), matching key features for both—ca. 20 unequal phyll (the outer ones are
generally smaller), 25—30 florets per head, a 3—4 ribbed achene, a pappus of ca. 40 capillary non-plumose
bristles, and a glabrous style base. Praxelis has been reported as an annual and a perennial (U.S. Forest
Service 2007, Waterhouse et al. 2003) and may behave as either, depending on local climate. A modified

Cronquist (1980) and FNAEC (2006b). All of these species are very different looking when placed side by side. These gen-
O are gece to ao the E macroscopic differences and are offered here to facilitate preliminary
field diagnoses. Agera , A. houstonianum, Praxelis clematidea, and some individuals of Chromolaena odorata

two). The hairs in Fleischmannia incarnata and many individuals of Chromolaena odorata and Conoclinium coelestinum are
small enouch and sparse enough to escape detection by the untrained naked eye. Chromolaena flowers are often a very

The genus Celtis L. (Cannabaceae, traditional Ulmaceae; Sytsma et al. 2002) is a widespread group of ca. 60
or 70 species of trees and shrubs, about half growing in the north temperate zone. Several Celtis species are
cultivated in North America. Most commonly cultivated are two native species, Celtis occidentalis L. (hack-
berry) and C. laevigata Willd. (sugarberry). Two exotic species, C. australis L. (native to the Mediterranean
basin and southwest Asia; Browicz and Zielinski 1982; Tutin 1991; Zielinski 1979) and C. sinensis Pers.
(native to China and Japan; Fu et al. 2004), are available in the nursery trade. Both are planted, primarily
as street trees, mainly in warm interior valleys of California (Brenzel 2001). Celtis sinensis is occasionally
planted in the eastern United States (Meyer et al. 1994; Dirr 1998), and is sometimes considered a species
with potential for more widespread use as a landscape tree (Dirr 1998).
Native Celtis species are well known to be weedy in gardens and disturbed urban areas. The single
report of C. australis escaping in Butte Co., California by Oswald (1994) is the only report of a non-native
Celtis sp. reproducing outside of cultivation in North America. No exotic species of Celtis is treated in any
continental or regional flora for North America (Barker 1997; Wilken 1993). However, Batianoff and Butler
(2002) considered Celtis sinensis one of the worst invasive plants in south-east Queensland, Australia, where
they found it capable of crowding out native vegetation and forming ltures, suggesting that the spe-
cies has the potential to become invasive in suitable conditions.
Herbarium specimens and field sites for Celtis were examined. Several Hen sites in California were
confirmed for C. australis and C. sinensis. The latter was also found to escape in g tion in the District
of Columbia.
Nesom (2000) suggests a simple, uniform terminology for describing the "reproductive status and
la success’ "BE non-native EE Uniform treatment of invasives is Se eg to allow
T rv
difficult to em to newly escaping woody plants or other pensis with long P times. Distin-
guishing between Nesom’s categories of “waif” and “naturalized” depends on the scientists’ estimate of the
long-term reproductive behavior of the species in the habitat. This is often suitable for annuals or perenni-
als that are short-lived or reproduce when young, but not suitable for woody plants, where it may be many
years before the long-term ability of a population to persist and reproduce in the habitat can be estimated
accurately—thus, before it can be known whether the population is naturalized. Unfortunately, the early

needed. it becomes important to document the habitats these species colonize and record their dispersal
distances from seed sources. Invasive species have often gone unrecognized for long periods because they
are not included in regional herbaria, floras, or other literature (Luken & Thieret 1995; Whittemore 2004).
These two species are not described or illustrated in any North American flora (except McMinn & Maino
1947, who included C. australis as a cultivated species). A key, descriptions and illustrations are provided
below to ensure that their populations can be recognized by local botanists.
TAXONOMIC TREATMENT
Identification of Celtis in North America is greatly complicated by unresolved taxonomic problems in a
variable complex of shrubs and small trees, distributed over most of the United States, that are probably
apomictic (Whittemore 2005a). These plants (referred to as the "small tree complex" below) are treated in
different fl under a variety of names (tl t commonly used, in the order they were first published, are
Celtis pumila Pursh, C. tenuifolia Nutt. € xélitulatà Torr., C. lindheimeri Engelm. ex K. Koch, and C. georgiana
Small). None of the published treatments presents the variation in these plants adequately. Furthermore, of
the five names listed above, only C. pumila and C. reticulata have been typified, and the correct application
of the other names is in question. Until an adequate taxonomic treatment of this complex is available, it is
not possible to write a full key to the North American Tes of EE Furthermore, Celtis shows a very high
level of within-plant leaf polymorphism, which greatly ification. Leaves of juvenile or highly
stressed plants are often very different from leaves of — adults with the same genotype, and leaves of
vigorous leaders may be much larger than Sis of fruiting laterals, and these two = ee a ie Sie?

Celtis australis can be recognized by its smooth or finely roughened bark (not developing corky warts or
ridges like the native North American species), its leaf blades that are sharply serrate and very slenderly
long-acuminate from a narrowly elliptical to lanceolate or lance-ovate body and uniformly felty-pubescent
beneath, and its large, dark brown or black drupes (the drupes ripen orange-brown, red or purplish in
other American species).
Celtis australis was reported by Oswald (1994) as an escape in Bidwell Park, Chico, California. This site
was visited in August 2006. The road between the site of the former Forestry Station and the current Nature
Center is lined with large, well-established trees, evidently planted many years ago and now fruiting heav-
ily. Seedlings and saplings are common in the vicinity of these trees. The Duden d are found in disturbed
roadside habitats, but well-established small t Iso found in open Q Platanus woodland
in the vicinity of the planted trees. Some of these trees are fruiting in this habitat, so C. australis is definitely
established in native habitats and should be considered locally naturalized.
Feral plants of Celtis australis were also found along a Rate on the ee Se of Davis, in ie
A
secondary forest that grew up on disturbed soil exp when the waterway
thirty years ago. No cultivated trees were seen nearby, but the storm-drain stem from much ob Davis Ense
ties into this waterway, so seeds could easily have washed in from elsewhere in Davis (where C. australis is

The site is worth noting, however, as it does suggest that C. australis is capable of dispersing over significant
distances.

Celtis sinensis can be recognized by its smooth bark, its rather leathery, glossy leaves, with the margins usu-
ally crenate or bluntly serrate and the apex often rounded-acute.
Celtis sinensis has never been reported to escape in North America, but field sites and herbarium
specimens were found documenting feral populations over a surprisingly wide geographic range and in a
variety of habitats. It is not common at any of the sites and there is currently no evidence that it can be an
aggressive competitor in our flora (as reported for Australia; Batianoff and Butler 2002), but saplings are
often found several hundred meters from possible seed sources, suggesting that effective dispersal agents
for this species exist in North America. On the grounds of the U. S. National Arboretum in Washington DC,
young trees are occasionally found in open margins of native deciduous forest, often 100—300 m from the
nearest possible seed source, but feral plants have not been observed in closed forest (except as a weed in
cultivated beds). The Butte County site (Castro 436) is riparian woodland in dry, grassy low foothills of the
northern Sierra Nevada, and according to the herbarium label, the feral plants are ca. 200 m from planted
trees of C. sinensis. The tree near Road 101A in Yolo County (Whittemore 06-012) is in native alkali grassland
that has never been cultivated but has probably been subject to some disturbance because of its proxim-
ity to the county road and railroad. This tree is at least 300 m from the nearest possible seed source. The
long dispersal distances seen at most of the sites are not surprising, since the sweet, fleshy drupes are well
suited to bird dispersal. Fleshy bird-dispersed fruit has been shown to be a significant predictor of invasive
behavior in woody plants (Widrlechner et al. 2004), so further tracking of this species is desirable.

In early December 2007, the USF herbarium received a specimen of an unknown aquatic grass collected
along ER northwestern shore of Lake Okeechobee, Glades County, Florida. The specimen was not satisfac-
torily identifiable as anything currently known in the state's flora (Wunderlin & Hansen 2003; Wunderlin
& Hansen 2008) and its morphological characteristics led to investigation of the genus Luziola.
Examination of the revision of Luziola (Swallen 1965) revealed that there are two named species of
very similar morphology, L. spruceana Benth. ex Dóll and L. subintegra Swallen. The material in question
was determined to be closer to L. subintegra, and this was confirmed by Gerrit Davidse (MO; determination
in duplicate). Consultation of the Flora of North America treatment of Luziola (Terrell 2007) and the USDA
PLANTS database un NRCS 2008) revealed that a taxon is ipe new to the United States flora.

bint known distribution from Mexi B through Central America and South
nea a to Argentina, and the Caribbean basin (Judziewicz et al. 2000). It is apparently rare in
Central America, at least in Costa Rica and Nicaragua (Morales 2003; Pohl & Davidse 2001).
Description.—Stoloniferous perennial, emergent, floating, mat-forming aquatic or prostrate-creeping
terrestrial. Culms nde to ca. d m long or more, 3-10 mm diameter, rooting from the nodes. Leaf sheaths

wide I rarely with a few
pistillate spikelets within the staminate panicle. Staminate panicle terminal! M spikelets 5—7 mm long,
with one fertile floret per spikelet; glumes absent or obsolete; palea 3-nerved; lemma 4 or 5-nerved, both
palea and lemma hyaline, similar; anthers 6(5—7) per floret. Pistillate panicle axillary, congested, 1—several
per culm, barely exserted from the sheath, the primary branches sharply recurved when mature, with evi-
dent pulvini, spikelets 3—5.5 mm long, with one fertile floret per spikelet; glumes absent or obsolete; palea
5-nerved; lemma 5-7-nerved, palea and lemma similar. Caryopses (achenes) with a hard, brittle pericarp,
minutely longitudinally striate, asymmetrically ovoid, to 2 mm long, with a persistent style base.
Luziola subintegra is unlike any other Luziola currently known to the United States. It is robust, with
large, thick culms, and has leaves with inflated, spongy sheaths and long, broad blades. All of our other
Luziola taxa can be described as delicate, slender plants with narrow culms, and shorter, narrower leaves.
Luziola subintegra gives the overall impression of being quite similar in habit to Paspalum repens P.J. Berguis
or to a lesser degree Hymenachne amplexicaulis (Rudge) Nees (Figs. 1-3).

In late December 2007, we investigated the extent of the population within Fisheating Bay, and found
it to be nearly ubiquitous there. The population consisted of two large, near-monoculture mats, one mat
of ca. 2 ha, to the east of Harney Pond Canal, and the other of ca. 80 ha, to the west of the canal (Fig. 3).
The locality of these two mats was within a portion of the lake bed that during the record low-water level
of early June 2007 was completely exposed and bare of all vegetation. Surrounding each of the large mats
and scattered throughout the open bay were sporadic, small clumps of one to several mature individuals. It
was also found as both an emergent aquatic and a terrestrial inside the mouth of Fisheating Creek. At this
location, the terrestrial individuals of a mature state were evident only in small, isolated clumps, and they
appeared to be less competitive against the other terrestrial flora.
Fisheating Creek is the only remaining unregulated inflow to Lake Okeechobee. Based upon this infor-
mation and the fact that L. subintegra is present in the creek, we speculate that Fisheating Creek is its point
of introduction into Fisheating Bay and Lake Okeechobee. Given the extent of the current population and

tions and monitor these new spontaneous occurrences of non-native species to evaluate their potential for
becoming the next wave of invasive species (Yatskievych & Raveill 2001). At present, non-native species
comprise approximately 21% of the Arkansas flora (Arkansas Vascular Flora Committee 2006), with 3%
annotated as invasive in Arkansas.
Our field work focusing on ruderals and recent escapes in urban has led to tl
of many non-native plant species being documented as new to Árkansas (Peck 2003; Peck & Service 2006;
Serviss et al. 2006, 2007a, 2007b), with many of the species locally well established when discovered. At
present, more Species are being documented as entering the Arkansas s than are pene lost from habitat
loss, fragment , or human disturbance. Additionally, we have ol flocalized
`
spontaneity in several species of non-native ornamental shrubs, and while the parent plants
were cultivated, substantial reproduction of offspring was documented in the local vicinity of these plants
(see end of paper for specimen data).

Pulaski County, Arkansas. Here it co-occurred with Egeria densa, Hydrilla verticillata, Marsilea quadrifolia,
and Myriophyllum spicatum. It was first discovered at this location in 2006 by Bob Spraggins, an accoun-
tant for the Arkansas Natural Heritage Commission, who brought it to the attention of Theo Witsell, staff
botanist of the same agency. In 2007 the locality was searched, and all five invasive species were noted as

Quercus acutissima Carruthers (Fagaceae). Sawtooth oak is native to Korea, China, Japan, and Vietnam.
It has been documented outside of cultivation in several states, including Alabama, ud BAUER,
Maryland, North Carolina, Mississippi, Pennsylvania, and Virginia. Though previously documented as pres
ent in the Arkansas flora (Arkansas Vascular Ve Committee 2006); specifically, it has been enel
outside of cultivation in 10 Arl ties (Cross, Drew, Hempstead, Jackson, Jefferson, Lincoln, Nevada,
Pike, Union, and most recently, Clark). Sawtooth oak has demonstrated the ability to escape cultivation
and subsequently naturalize in many areas of the eastern U.S., especially when cultivated plants are in the
vicinity of open areas, such as grasslands and disturbed woods (Whittemore 2004). Hence, it appears to
have the potential to become invasive in Arkansas, and its current known distribution in the state seems
worthy of note.

ADDITIONAL NOTEWORTHY SPECIES
The following six non-native, woody, angiosperms were documented as spontaneous offspring in the im-
mediate vicinity, or within a short (several meters) distance from the vicinity of cultivated and reproductive
individuals of these species. Documentation of these initial reproduct by cultivated non-native
plants is essential for dating their initial entrance into the flora by other than the dent assistance of human
activities. Additionally, the ability of these species to successfully reproduce offspring is significant in that
probably with regard to most of the non-native and invasive ornamentals in the U.S., their initial “entrance”
into the flora was accomplished in similar fashion to the following examples. It is therefore crucial to rec-
ognize and sul tly document these initial occurrences of spontaneity in non-native plant species. All
six of the lonas species have displayed successful reproduction in Arkansas, evidenced by the presence

of few to many spontaneous juveniles being present within a short distance of cultivated reproductive age
plants of their respective species.

INTRODUCTION
Recent floristic work in nort] tern Louisiana has resulted in the di of plants new to Louisiana and
other significant records (Reid & Faulkner 2006; MacRoberts et al. 2007; Reid et al. 2007). In this paper we
report four species new to Louisiana and four additional significant collections.
ALISMATACEAE
Sagittaria subulata (L.) Buchenau—Sagittaria subulata is not reported for Louisiana by USDA, NRCS
(2007), Haynes and Hellquist (2000), Kartesz and Meacham (2005), MacRoberts (1984), or Thomas and
Allen (1993). On 27 June 2006, we discovered hundreds of plants on a stretch of shoreline on Caddo Lake
at Oil City, northern Caddo Parish. According to Haynes and Hellquist (2000), S. subulata ranges from Mas-
sachusetts south to Florida and west to Mississippi. Our record extends the range of S. subulata over 500
km to the northwest of its previously known western range limit in Mississippi.

ASTERACEAE
Grindelia lanceolata Nutt.— Grindelia l latai ted for Louisiana by Riddell (1852) and Steyermark
(1934). Steyermark (1934) cites Leavenworth specimens at G (= GH) and NY as his authority. MacRoberts
(1984 and Thomas and Allen (1996) include G. lanceolata in the Louisiana dee on He basis of these older
literature reports. We discovered G. lanceolata on 20 June 2007 int ine
Parish. The plants occurred on open slicks with overall light vegetative cover. Daca a return visit on 7
August 2007, we observed an estimated 500 plants, many of which were beginning to flower. Our record of
G. lanceolata is apparently the first in Louisiana since Leavenworth’s time, ca. 150 years ago (Ewan 1968).

Senecio ampullacens Hook.—Senecio ampullaceus is not reported for Louisiana by MacRoberts (1984),
Thomas and Allen (1996), Kartesz and Meacham (2005), USDA, NRCS (2007), or Barkley (2006). On 28
March 2007, we discovered a population of S. ampullaceus in the xeric sandhills (M.H. MacRoberts & B.R.
MacRoberts 2006) of northern Caddo Parish. It was recently reported new to Arkansas (Singhurst & Hol-
mes 1998) and Oklahoma (Holmes et al. 2006). Our record is apparently the first for 5. ampullaceus from
Louisiana.

Faulkner (LSU).
BRASSICACEAE
Arabis canadensis L.—On 13 April 2006, we discovered a small population of Arabis canadensis in De
Soto Parish growing on a low ridge embedded in a matrix of poorly drained Quercus similis — Crataegus spp.
flatwoods. MacRoberts (1989) and Thomas and Allen (1996) include A. canadensis in the Louisiana flora on
the basis of a specimen collected by Leggett (1578 — NLU) from Bossier Parish. Leggett (1976) reported it
from one station in Bossier Parish where it was "localized and uncommon on sandy soil in mixed woods.
During recent visits to NLU, we have failed to locate this specimen. It is apparently not on loan and may
have been misfiled or annotated to another taxon. Providing that the identification and locality data are
correct, our record is the second from Louisiana. If the Leggett specimen was misidentified, then our re-
cord is the first for the state. In either case, our record represents the only confirmed extant A. canadensis
population in Louisiana.

CARYOPHYLLACEAE
Geocarpon minimum Mackenzie
Arkansas, Louisiana, Missouri, and Texas (Niendlier 2005). This Peel was initially discovered in Louisiana
in Winn Parish in 1989 with an additional population discovered nearby in 1992 (McInnis et al. 1993).
These were the only two Louisiana populations known until 2006 when a third occurrence was discovered
in a saline prairie in Caddo Parish (B.R. MacRoberts & M.H. MASON 2006). A survey for G. minimum in
saline prairies in Caddo, De Soto, Red River, and Winn parishes was ted in March 2007 (MacRoberts
& MacRoberts 2007) that yielded three new sites representing two new populations, all in De Soto Parish.
Because two of the collection sites, Dickson Prairie ane Daten ue are bi co by a narrow drainage,
a Geet is federally listed as threatened and is known from
we regard G. minimum from these two sit lation. The third collection was from
another saline prairie, Rambin Bayou Prairie, which is well removed from the other sites.

Lechea san (Buckley) Hodgd Lechea san-sabeana was reported for Louisiana by Riddell (1852) as
Lechea drummondii Torr. SA. Cay and luded from the flora by Thomas and Allen (1996). MacRoberts
(1984) lists L. san-sabeana as questionable in Louisiana and cites the Riddell report. Correll and Johnston
(1970), Carr (2002), Kartesz and Meacham (2005), and Diggs et al. (2006) regard L. san-sabeana as a Texas
endemic. In May and June 2007, we collected L. san-sabeana at three saline prairies in De Soto and Caddo
parishes. It was common at these sites and was associated with pimple (mima) mounds.

CYPERACEAE
Carex arkansana (L.H. Bailey) L.H. Bailey—Louisiana is not included in the range of Carex arkansana by
Ball (2002) but is so included by Kartesz and Meacham (2005), USDA, NRCS (2007), NatureServe (2007),
and Thomas and Allen (1993). MacRoberts (1989) and Thomas and Allen (1993) cite a specimen from Caddo
Parish (Thieret 25936 — LAF) collected in 1967 as the only record for Louisiana. B.R. MacRoberts and M.H.
MacRoberts (2006) examined this specimen and confirmed its identification. On 2 May 2006, the authors
discovered a small population of C. arkansana growing in a depression in a saline prairie in De Soto Parish.
On 4 May 2007, we found a much larger population in a wet swale in a different part of the same prairie
complex, adjacent to Quercus similis-Crataegus brachyacantha flatwoods. Our record is only the second record
for this species in Louisiana and came 40 years after Thieret first collected it from the state.

POACEAE
Panicum diffusum Sw.—On 20 June 2007 we found Panicum diffusum to be locally common in a saline
prairie remnant in Sabine Parish. It was iated with open slicks with much bare soil and light vegetative
cover. This record is apparently the first for Louisiana as the species is not reported for the state by Nature-
s (2007), Mid NRCS (2007), Thomas and Allen (1993), Allen et al. (2004), nor Freckman and Lelong
icum iously known in the United States only from Texas; its range extends south
(
to the Caribbean and Latin p (Diggs et al. 2006; Freckman & Lelong 2002).

Silene flos-cuculi (L.) Clairv. ssp. flos-cuculi (syn. Lychnis flos-cuculi L.), Ragged Robin, is a showy intro-
duced taxon in the Caryophyllaceae with deeply dissected, pink petals. This perennial European native is
presumed to be established in the northeastern United States (Weakley 2007), but has also been reported
in several other U.S. localities, including fifteen states and the District of Columbia. States with records of
this plant are Connecticut, Maine, Maryland, Massachusetts, Montana, New Hampshire, New Jersey, New
York, Ohio, Pennsylvania, Rhode Island, Vermont, Virginia, Washington, and Wisconsin (USDA, NRCS
2007). Silene flos-cuculi ssp. flos-cuculi in abundance, with approximately four individuals observed
in an old-field across from Rich Hill Church in the rural Glade Valley community. Associated taxa include
Dactylis glomerata L., Pinus virginiana Mill., Pteridium aquilinum (L.) Kuhn var. latiusculum (Desv.) Underw. ex
A. Heller, Rubus argutus Link, and Sassafras albidum (Nutt.) Nees. The four-lobed, lacerate petal morphology
and pink coloration differs substantially from other Silene spp. in North Carolina.

INTRODUCTION
This manuscript is the 5th part of an intended inventory, based on voucher specimens, of the vascular flora
of the Big Thicket National Preserve, southeastern Texas. In 4 previous papers, we provided an annotated
checklist of the Hickory Creek, Turkey Creek, Big Sandy Creek, and Lance Rosier units (MacRoberts et
al. 2002; Brown et al. 2005, 2006a, 2006b). In this paper, we provide an annotated checklist of the Beech
Creek Unit.
SITE AND METHODS
The Big Thicket is located mostly within the longleaf pine region of the West Gulf Coastal Plain in south-
eastern Texas (Ajilvsgi 1979; Harcombe & Marks 1979; Watson 1979; Marks & Harcombe 1981; Harcombe
et al. 1993; Diggs et al. 2006 and references therein). The Big Thicket National Preserve consists of 12
units scattered over 7 Texas counties. The units range from 222 to 10,100 hectares and total about 34,000
hectares (Peacock 1994). The Beech Creek Unit consists of 2,059 hectares and is located in western Tyler
County (Fig. 1). It is relatively flat with poor drainage over most of the area. Elevation ranges from about
43 meters to 62 meters. Little Beech Creek and Beech Creek run through the unit. The Beech Creek Unit
was chosen for inclusion in the Big Thicket National Preserve because of its extensive stands of beech forest
(Ajilvsgi 1979; Harcom be & Marks 1979; Watson 1979; Marks & Harcombe 1981). It is dominated by lower
slope hardwood-pine forest (mesic lower slopes and terraces), with lesser amounts of baygall, mid-slope
oak-pine forest, floodplain hardwood-pine forest (mesic stream bottoms), and floodplain hardwood forest
(seasonally flooded river floodplain) (Harcombe & Marks 1979; Marks & Harcombe 1981; Van Kley 2006).
A map of community types can be found in Harcombe and Marks (1979). Fire suppression over the past
30 years has resulted in extensive midstory development and thus reduction of herbaceous vegetation that

is adapted to frequent fires. Hurricane Rita, a category 3 hurricane, passed over the unit on 24 September
2005 damaging and toppling thousands of trees. It will probably take decades for this litter to decompose.
Details about soils, topography, and climate can be found in Deshotels (1978); Watson (1979, 1982, 2006),
Harcombe and Marks (1979); Marks and Harcombe (1981); and Diggs et al. 2006).
Like most units of the Big Thicket National Preserve, the Beech Creek Unit has not been the subject of
a detailed floristic inventory.
Larry Brown collected 290 specimens during 9 field days beginning 9 November 2006 and ending 17
October 2007. The MacRoberises collected 154 specimens during 4 field days in 2004 and 1 day in 2007.
Suzanne Walker collected 101 specimens during 2 days in 2004 and 1 additional day in 2007. Sandi Elsik
and Warren P together gathered 82 specimens during 2005. Geraldine Watson collected 25 specimens

over several years in the late 1970s and early 1980s. Warren Pruess collected another 11 specimens over a
2 year period. Other collectors totaled 12 specimens. We c

ditional specimens but found no additional taxa not reported here.
Because our purpose was to produce a list of taxa known to occur on the Beech Creek Unit, a vouchered
specimen was considered to be the only evidence acceptable for inclusion in the list. In all, 675 herbarium
specimens form the data for this report. All specimens have been annotated by Larry Brown.
In most cases, nomenclature follows Jones et al. (1997), Kartesz (1999), Turner et al. (2003), and Diggs
et al. (2006). In cases of multiple collections, no more than 4 are listed for each taxon.

ÁDDENDUM
J
Isotria verticillata (whorled pogonia) and sugar maple Ge DER SE m or Ácer leucoderme) are
listed for the unit on the Beechwoods Trail Guide, a e at the trail entrance, but
ve failed to collect them during our two- year field survey, dud Seef not find herbarium material of same.
Geraldine Watson (2006) also indicated that sugar maple (Acer barbatum) is making a remarkable recovery
in this unit with the removal of cattle grazing.
NOTES
Carex section ovales. The specimen in this collection was too immature for specific identification. The
only other Carex in section ovales was C. brevior. Perhaps this was an immature C. brevior.
Bartonia texana. Currently Beech Creek is the only Big Thicket unit to have this rare Texas endemic. We
made two collections, one in a sphagnum mat along the Beechwoods Trail, and one far from any trail, near
the intersection of Beech Creek with Little Beech Creek.
Bradburia pilosa. We are following Semple (2006). An equally correct name is Chrysopsis pilosa Nutt.

Xyris jupicai. There is no consensus as to the native or introduced status of this yellow-eyed-grass.
DISCUSSION
There are 103 families and 229 genera represented for the 470 taxa (418 native) on the Beech Creek Unit list.
Eight families: Poaceae (59 taxa), Asteraceae (53 taxa), Cyperaceae (40 taxa), Fabaceae (26 taxa), Lamiaceae
(15 taxa), Euphorbiaceae (13 taxa), Scrophulariaceae (11 taxa), and Juncaceae (11 taxa) account for 48.9%
of the taxa collected. The largest genera are: Carex (15 taxa), Dichanthelium (13 taxa), Rhynchospora (11 taxa),
Juncus (10 taxa), Quercus (9 taxa), and Cyperus (7 taxa).
While it is the case that our list is i plete, as are all floras, and that a few taxa reported here may no
longer exist on the unit, specimens of most taxa that have grown in the Beech Creek Unit during the past
quarter century have been collected (probably 954 96). We estimate that the Beech Creek Unit has about
425 to 450 native species/taxa.

los modernos. Dos lo describen como un matorral, y otros dos como bosques abiertos
There is much disagreement on what should be called the Big Thicket (Cozine 2004; Diggs et al. 2006).
The broadest conception has it encompassing about 3.5 million hectares in an area extending from the
Brazos to the Sabine rivers and from Nacogdoches to Beaumont. The narrowest conception is the “Hunters
Thicket” encompassing only 130,000 hectares mostly in Hardin County. Today, the most generally ac-
cepted view corresponds more or less to a compromise between the Biological Survey definition of Parks
and Cory (1938) and the Ecological Area definition of McLeod (1971). In this view it encompasses more or
less Jasper, Newton, Tyler, Hardin, Polk, San Jacinto, Montgomery, and northern Liberty counties: about
1.8 million hectares (see Diggs et al. [2006] for a detailed discussion of literature and maps of the various
locations of the Big Thicket).
Del Weniger, the eminent ecological historian of Texas, argued that the phrase “Big Thicket” was not
old but dated from only the mid-nineteenth century and that today's location of the Big Thicket is not where
it originally was (Weniger 1984). The two earliest (pre-1860) accounts he was able to find which used that
phrase were by Don E.E. Braman and J. De Cordoba, from 1857 and 1858, respectively. These accounts
place the Big Thicket on the San Jacinto River or between the two forks of the San Jacinto River in what are
now San os TOM MEN and pes Me counties, to Aa west or at dps western edge of where
modern te it (county | ange bly since the 1850s) (Fig. 1). These two
sources do not describe the Big Thicket as an SEM forest but as a highly desirable region of mostly
large, dense timber with fertile and productive soil that was already extensively settled by the late 1850s.
Diggs et al. (2006) recently described a third pre-1860s account of the Big Thicket. This is in A Stray
Yankee in Texas, published in 1853 by Philip Paxton (Paxton 1853). As Diggs et al. (2006) only briefly men-
tion this reference, additional comment seems warranted. Philip Paxton (a pseudonym for Samuel Adams
Hammett, 1816-1865) was born in Connecticut and moved to Texas in 1835 where he remained until 1848
working in and around Montgomery and Houston. Upon his return east, he wrote serious and humorous
magazine articles about Texas. In 1853 he published these as A Stray Yankee in Texas (Hoole 2007). Paxton's
account of the Big Thicket is interesting for two main reasons. First, he places the Big Thicket on the San
Jacinto River, which, as in the accounts of Braman and De Cordoba, is west of or on the western edge of where
current descriptions locate it. Second, unlike Braman and De Cordoba, Paxton describes the Big Thicket
as a thicket. According to him, the Big Thicket, while having "the finest timber in the world" is *a thicket
so dense that even in that Eon. of uM forest, it is known—par excellence—as the big thicket...." He
continues: “This spot had been aptly named the “big thicket.' Immense bamboo briers, like vegetable Pythons,

twined and intertwined, crossed and recrossed, from tree to tree, and shrub to shrub, forming a natural
trellis-work for the thousand and one wild and beautiful vines that abound there.” Further, he writes: “The
first part of our journey was effected on horseback; but after proceeding some half a mile into the ‘timber,
this mode of progression was suddenly brought to a period by the dense undergrowth, and we were reduced
to a very natural and primitive style of locomotion.” Finally, he adds: “We now had to contend for every step
we gained; knife and hatchet were in constant requisition, and for one hour we pressed on in Indian file as
fast as we could.” Paxton describes or refers to such plant habitats as “cypress-brakes,” “palmetto swamps,”
“cane-brakes,” “sloughs,” and “prairies.” He mentions individual plants: “magnolia grandiflora,” “bamboo,”

“passion vine,” “cypress vine,” “morning-glory” “trumpet-creeper,” “cypress,” “hanging-moss” (Spanish moss),
and “cane,” and animals: “log-cock” (Pileated woodpecker), “paroquet” (Carolina parakeet), “mocking-bird ”
“moccasin snake,” “alligator,” “bear,” and “fish.”
With the aid of Parker’s bibliography (1977), we located another early account. This occurs in an article
“The Big Thicket Ruins” in The Texas Republic, 3 May 1856. The relevant passage reads: “A man by the name
of Smith, reported to the Washington American about the First of April, that he had recently discovered in
the Big Thicket on the San Jacinto some twenty-five miles from Montgomery, an ancient ruin....” (italics in
original). The article goes on to describe these ruins as being in “a dense thicket almost impenetrable.”
Thus, all four of the earliest known references to the Big Thicket place it on the San Jacinto River or
between the forks of the San Jacinto River on the western edge of the generally accepted conception of the
Big Thicket (Diggs et al. 2006), or as Weniger (1984) stated: “this places the Big Thicket in the area of present
Montgomery and San Jacinto counties, roughly between Conroe, Cleveland, Coldspring, and Huntsville,”
which is basically what is today the Sam Houston National Forest. To our knowledge, there are no early
accounts that place the Big Thicket in Hardin, Tyler, Jasper, Newton, Liberty, or Polk counties or on the
Sabine, EEN or Trinity rivers where PES scholars bis it and where the Big Thicket National
1. But, both Paxton’s and Smit] t t Weniger's finding that the Big Thicket
was originally described as an open and hospitable land. Both accounts clearly describe the Big Thicket as
virtually impassable.
Why and when the phrase “Big Thicket” came to be applied to tl tern region ins unknown.
If anyone knows of other pre-1860 references to the Big ‘Thicket or has information on the evolution of the
concept of the “Big Thicket,” we would appreciate hearing from them.

INTRODUCTION
The Big Thicket has been described as an area where many floras converge (see MacRoberts & MacRoberts
2004, 2007; Diggs et al. 2006 for discussion and literature). This characterization has been questioned
(MacRoberts & MacRoberts 2004a; MacRoberts et al. 2007). The affinity of the Big Thicket flora is almost
entirely within the eastern and especially southeastern U.S.A. (Diggs 2002; Diggs et al. 2006; MacRoberts
& MacRoberts 2003, 2004a, 2007; McLaughlin 2007)
The present study originates from a statement in Diggs et al. (2006:171): “While clearly part of the
southeastern U.S., the Big Thicket represents the southwestern extreme of the Southeastern Mixed Forest
Province and the Outer Coastal Plain Mixed Forest Province.... Hundreds of species that occur in an arc
from Virginia or North Carolina south to Florida and west to Texas reach the southern or southwestern
limit of their ranges in the Big Thicket, or are confined or largely confined in Texas to the Big Thicket area.
The reasons for their occurrence in the Big Thicket include the high rainfall and overall mesic conditions
and the presence of specialized habitats. .
As part of a continuing effort to describe and understand the flora of the Big Thicket region (Parks &
Cory 1936; Watson 1975; Ajilvsgi 1979; Marks & Harcombe 1981; Bridges & Orzell 1989; Harcombe et al.
1993; MacRoberts & MacRoberts 2004a; MacRoberts et al. 2002, 2007; Brown et al. 2005, 2006a, 2006b,
in press; Diggs et al. 2006), we concentrate in this study on what is unique floristically to the Big Thicket
region in Texas and how this flora relates to abiotic conditions.

Southeastern Texas (in which the Big Thicket ) y, geologically, and phy y related

of the eastern United States to receive such large amounts of precipitation (Diggs et al. 2006). Additionally,
precipitation is well distributed through the year, the difference between driest and wettest month being
only a few centimeters (Bomar 1995; Diggs et al. 2006). The only significant variation in elevation in the Big
Thicket region is connected to the Willis and Fleming formations to the north where elevation rises to 110
meters and where water runoff is fairly rapid. To the south on the Lissie and Beaumont formations there is
little or no relief and the area is poorly drained. Because of high precipitation and flat terrain, soils
waterlogged, and water may stand for long periods of time in some areas, e.g., wetland pine savannas, bald-
cypress sloughs, and palmetto-hardwood flats (Bridges & Orzell 1989; Marks & Harcombe 1981; Harcombe
et al. 1993; Diggs et al. 2006). Additionally, because of high rainfall, the soils—Ultisols and Alfisols—are
often deeply weathered. The relatively low latitude (approximately 30 degrees N) and proximity to the Gulf
of Mexico result in uniformly high temperatures and a long humid growing season (Bomar 1995). South-

eastern Texas has the highest net above-ground primary productivity in Texas (Owen & Schmidly 1986),
a net primary productivity comparable to the southeastern United States.
METHODS
Using the plant distribution maps in Turner et al. (2003) and Diggs et al. (2006), we developed a list of 98
native species “unique” to the Big Thicket region in Texas. This list consists of all species that are either
confined entirely to the Big Thicket in Texas (wherever else they occur in North America) (e.g., Spiranthes
longilabris Lindl.) or that are concentrated in but not totally confined to the Big Thicket in Texas (wherever
else they occur in North America) (e.g., Xyris scabrifolia Harper). Using sources available (e.g., Diggs et al.
2006; MacRoberts et al. 2002), we determined in which habitats (communities) these species occur. Some
species occur in more than one community; consequently, we divided their representation between those
communities. Using USDA (2007), we determined the wetland status of each species. For those with no
wetland rank, we either assigned one based on our personal experience, or, if we did not know the species
adequately, put them in the “unknown” category. Using Kartesz and Meacham (2005) and Flora of North
America (1993-2006), we plotted the North American distribution of the species to determine their rela-
tionship to other regions.
In order to put the Big Thicket into a larger context, using Turner et al. (2003) and Diggs et al. (2006)
we developed a random selected list of 115 native species confined to eastern Texas but that were evenly
distributed over the area, not just the Big Thicket, irrespective of wherever else they occurred in North
America. As with the Big Thicket list, we determined, where possible, in which habitat (communities) these
species occurred and their wetland status. Using the same sources as for the Big Thicket list, we plotted their
North American distribution.
For the purposes of the present study, the Big Thicket is defined as Jasper, Newton, Hardin, Tyler,
Polk, San Jacinto, and northern Liberty counties. This definition corresponds closely with the “biological”
definition of the Big Thicket and is the same as that used by Diggs et al. (2006). Eastern Texas is defined as
the area of Texas east of about 97 degrees longitude.
RESULTS
We found 98 species that are either unique to the Big Thicket or that are concentrated in it within Texas
(irrespective of where they occur outside Texas). The community preferences, where they could be deter-
mined, are given in Table 1: 65 percent of the species favor wetland communities. The wetland status of
these species, where known, is given in Table 2: 67 percent are obligate or facultative wetland species. The
North American distribution of these species as a percentage of the total is given in Figure 2: 96 percent
occur in Louisiana, 94 percent in Mississippi and Alabama, 91 percent in Georgia and Florida, 85 percent
in South Carolina, 81 percent in North Carolina, and 56 percent in Virginia, all of which are coastal states.
Percentages drop off precipitously for all other states, regions, and provinces.
The eastern Texas sample had 115 species: 19 percent favored wetland communities (Table 1) and
28 percent were obligate or facultative wetland species (Table 2) (the discrepancy between the two figures
is probably due to the high number of unknowns and the high number of plants undesignated by USDA
[2007]). The North American distribution of these species is given in Figure 3. The distribution is mainly
in the South, but also the East in general.
DISCUSSION
In the past, the Big Thicket has been characterized as an area in which the floras of many regions converge.
In a recent study (MacRoberts & MacRoberts 2007), we found that the Big Thicket is almost entirely south-
eastern with a flora composed of species typical of Louisiana, Mississippi, Alabama, and the East in general,
not of species typical of western or central states. The only exceptions to this are prairie species (Brown
et al. 2002). However, the Big Thicket is not the only part of the West Gulf Coastal Plain that has prairies.

uniqueness of the region. As might be expected, considering that southeastern Texas is humid subtropical
and the wettest area in Texas, the plants are largely wetland species. Also not unexpected, considering that
the southeastern United States has virtually the same climate as does southeastern Texas and that both
areas are edaphically, geologically, and physiographically similar, plants that are unique to the Big Thicket
in Texas are also found in Louisiana, Mississippi, Alabama, Florida, Georgia, Virginia, and the Carolinas,
all of which are coastal states with high rainfall and thus deeply weathered soils.
This conciusion is supported by our analysis of the eastern Texas plant group. While two-thirds of
670 J l [| Eal Dos H In LL) de e a f Texas 2(
the species confined to the Big Thicket region are wetland species, only one-quarter of the eastern Texas
group are. Additionally, the North American distribution of these species is significantly different from the
Big Thicket group. Instead of hugging the southern coastal states, they are distributed across eastern North
America.
Further support for the thesis that the Big Thicket is characterized ee by wetland plants is e
fered by Diggs et al. (2006:169), who found that the Big Thicket is relatively rich in monocots when compare
to other areas of Texas. They speculate that this difference probably Ke to high percentage of mesic to
wet habitats favored by many monocot species.
Another indicator of the importance of precipitation in the Big Thicket is the presence of drought-
intolerant American beech (Fagus grandifolia Ehrh.), which reaches its westernmost limit in the United States
in Montgomery and San Jacinto counties (McLeod 1975; Diggs et al. 2000).
In conclusion, southeastern Texas and thus the Big Thicket is the westward abiotic extension of the
southeastern United States and thus also its westward phytogeographic extension. Many southeastern
species reach their distributional limit in southeastern Texas because of its high precipitation and edaphic
conditions resulting from that high precipitation.
Thus, as Diggs et al. (2006) point out, the Big Thicket represents a biological boundary and is therefore
important for a number of reasons. For example, populations at the margin of a species’ range are often
| ble resource. Also, peripheral populations are often more
unique genetically and represent an irreg
sensitive to environmental change and can act as ecological indicators. More locally, the Big Thicket is
important because it is a unique area within Texas, and the Big Thicket National Preserve is one of the few
relatively large protected areas in the entire West Gulf Coastal Plain serving as a refuge not only for species
and communities in Texas but the entire area as well.

INI RODUCTION
Ecophysiology of seed germination is very important for the conservation of endangered species as it is a
key factor of reproduction and will therefore strongly aid in restoration strategies. For aquatic and wetland
plants, it is essential to know if germination rates are affected by soil water-levels (Sifton 1959; van der Valk
1981; Keddy & Ellis 1985; Kellogg et al. 2003). This information will help in making decisions regarding
where in an aquatic system seeds should be planted.
There are three species in the genus Zizania L. in North America: Z. aquatica L., Z. palustris L., and Z.
texana Hitch (Terrell et al. 1997). Each of these species grow in aquatic environments, but Z. texana may
require flowing water for stable existence (Power 1996; Poole & Bowles 1999), while the other species can
be found in stagnant water on the edges of lakes or along muddy shores of slow-moving streams that are
subject to constant changes in water levels (Archibold & Weichel 1986; Pip & Stepaniuk 1988). Zizania
texana is a federally listed endangered species endemic to the San Marcos River, San Marcos, Hays County,
Texas, U.S.A. The distribution of Z. texana is restricted to the upper 2.4 km of the river, within mean water
depths ranging between 0.72 to 0.83 m, and mean velocities ranging between 0.38 to 0.93 m/s (Poole &
Bowles 1999).
Historical documents that portray Z. texana growth in the San Marcos River describe the plant as
growing bank to bank, including irrigation waterways (Silveus 1933; Terrell et al. 1978). The San Marcos
River is spring-fed and river flow relies on the spring outflow as well as runoff. When outflow and runoff
are low, such as during times of drought, the area near the banks may not always be covered by water. This
may mean that, at times, Z. texana grew without flowing water or germinated in non-inundated soils. The
purpose of this study was to evaluate the response of seed germination of Z. texana to soil inundation. For
this study, I test the hypothesis that Z. texana seeds need to be in inundated soil for successful germination.

MATERIALS AND METHODS
Approximately 3,375 cm? of soil consisting of one third pea gravel to two thirds of an equal mixture of
compost, top soil and sand was placed into each of M 45 x 30 x 13 cm clear plastic rectangular containers.
Soil mixtures were saturated with water from the E d ifer (the same water source as the San Marcos
River) until the point at which pooled water just began to become visible on top of the soil. Seeds used for
the study were collected randomly from container grown plants growing in the San Marcos National Fish
Hatchery and Technology Center that were initially collected from the San Marcos River following tech-
niques recommended by Richards et al. (2007) for the best genetic representation of the wild population.
We used a total of 50 seeds for this study. Because this endangered plant has such a small population size,
there are only a small number of seeds available for scientific studies. The seeds were collected four months
prior to the experiment, in September 2006, and preserved in a refrigerator at 4 °C in moist paper towels
within sealed plastic bags, allowing for optimal germination conditions (Rose & Power 2001). Lemna and
palea were kept intact as their presence does not change germination probability and as it also mimics the
natural condition in this species (personal observation). Five seeds of approximately equal size were placed
equidistant to each other (5 cm apart) in the containers of saturated soil at a 4 cm depth. All containers
were placed into a growth chamber set to a 12-hour photo period at 20 — 23 ?C. Water was added slowly
to the five containers receiving the inundated treatment until it covered the soil with 2.5 cm of water. Each
inundated treatment was paired next to a non-inundated treatment within the growth chamber. Every
24 hours, any water loss within the 10 containers was compensated for, seeds were visually examined for
signs of germination, and the total number of germinated seeds was recorded. Seeds were considered to
have germinated when the radical had visibly emerged from the pericarp. Since Power and Fonteyn (1995)
found that most seeds of Zizania texana germinate within a 10-day period, following a 4-week period of
daily visual examinations the study was terminated. A paired t-test was run in order to determine if there
is a significant difference between the germination success rates of the two treatments, non-inundated and
inundated (analysis performed using SYSTAT v.10 statistical package).
RESULTS
Sixteen of the 25 total seeds in inundated soil and four of the 25 total seeds in non-inundated soil germinated
within the 4-week period (Fig. 1). Germination success S ter in inundated soil than in non-inundated
soil (paired t = 4.7, df = 8, p = 0.009; Mean difference = 2.4; : 95% C.I. = 0.98 to 3.82).
DISCUSSION
In this study, more Z. texana seeds germinated in inundated soil than in non-inundated soil. This may be
because Z. texana seeds are recalcitrant and do not survive for long outside of water (Horne & Kahn 2000).
The seeds may more readily germinate in inundated soil than in non-inundated soil because Z. texana are
so sensitive to desiccation.
Zizania texana is considered a perennial grass (Terrell 2007). In its current distribution within the
San Marcos River, Z. texana plants are, for the most part, submerged year round (personal observation)
and rarely flower (Emery 1966, 1977). There is a possibility that the species has an annual form as well in
certain environments. This species is a CO, obligate (Power & Doyle 2004). It may remain in perennial
form if growing in current velocities such that the boundary layer surrounding the leaves is small enough
to take in CO, for photosynthesis. However, if in stagnant, or slow moving currents, an individual plant
may become emergent in order to take in CO, from the air (where it is much more abundant), flower, seed,
and then die (i.e., annual growth form). If this species were to grow in its historic range of bank to bank, it
may be possible that some of the plants would become annuals and grow in areas of low flow and shallow
water. Because the seeds do not germinate as well in non-inundated soil, the San Marcos spring-flow has
to continue to be high enough (>100 cubic feet per second) that the soil at the banks' edge is consistently
inundated. Currently, Z. texana is inhibited from growing along the shallow, low flow banks because Colo-

casia esculenta (wild taro) has invaded and dominated the edges of the San Marcos River (Akridge & Fonteyn
1981; Nelson & Getsinger 2000).
The results of this study will aid in future restoration efforts for this endangered aquatic plant. With
data that supports the planting of seeds in inundated soil, all areas chosen for planting should be covered
in water during average spring flows. Restoration efforts of Z. texana should include planting in both low
and high flow areas to support both perennial and annual forms of the plant. This would have to include
the removal of C. esculenta in order to make the river-edge habitat available for the endangered Z. texana.

Habitat models developed from Geographical Information Systems (GIS) are useful tools for predicting the
distribution of rare species, decreasing the ineffectiveness of random surveys, providing potential sites for
relocation, and aiding the overall development of conservation management plans (Vogiatzakis 2003; Imm
et al. 2001; Wu & Smeins 2000). Van Manen et al. 2005) developed a predictive GIS-based habitat model

derived from the variables of known plant locations for a variety of species in Shenandoah National Park,
VA. The efficacy of their predictive model at locating species of interest was 4.5 to 12.3 times more efficient
than random surveys. Husveth (2003) used a baseline GIS model generated from observed plant locations,
surficial geology, and major soil associations to predict likely sites for rare plant species in a 15,378 ha plot
of Anoka County, MN. Field validation surveys (i.e. ground-truthing) of this model revealed additional
rare plant populations as well as high to medium quality habitats for rare species. Although the predictive
capabilities of GIS-based models are only as good as the variables used to generate them, they can provide
useful insight into the dependency of rare species on habitat variables.
The Guadalupe Mountains violet (Viola guadalupensis Powell & Wauer) is a rare and unique species of
wildflower endemic to the highest elevations of the Guadalupe Mountain range in West Texas. The species
was described in 1990 within Guadalupe Mountains National Park (GMNP; Fig D, Culberson County, TX,
and since its discovery has only been recorded from a single location along the East Rim of Frijole Ridge
(Fig 2; Powell & Wauer 1990).
At its type locality, this perennial, yellow-flowered violet grows in mats of Bp to e individuals rooted
in small openings of a northwest-facing, dolomitized, limestone rock face y 2,600 m above sea
level (Powell & Wauer 1990). The plants are well shaded by two large Beet firs (Pseudotsuga menziesii
in ) and pow in association with rock spi (Petrophytum caespitosum [Nutt.] Rydb.), Guadalupe valerian
Steyernm.), small rocklettuce (Pinaropappus parvus Blake.), Guadalupe leastdaisy (Chaeto-
pappa hersheyi Blake.), littleawn needlegrass (Achnatherum lobatum Swall.), and a species of sedge (Carex sp.;
Powell & Wauer 1990)
Little is known about this species’ natural history or the specific habitat characteristics needed to
maintain its viability. Speculation has been made of its dependency on microclimatic conditions and
substrate type; however, these data have only recently been recorded (F. Armstrong, pers comm.). Average
temperature from January 2003 to January 2004, at the type locality, was approximately 12.78°C. Relative
humidity during the same time interval ranged from <10 to 100% and daytime light intensity during the

counts, attempts to germinate see dlings in the laboratory discovered
that chilling seeds and treating them with De MW: allowed for successful germination (n = 5; C.
Blaxland, pers comm.). Seedlings in potting soil became chlorotic, but when lime was added they regained
green coloration indicating an affinity for alkaline substrate e PLE pers comm.). Although baseline
data have been collected, no intensive ive analysis or sig t research has been done at the risk
I
of damaging the population.
Thorough investigations to locate additional populations in seemingly suitable habitat have been con-
ducted along 8 km of the East Rim of Frijole Ridge from the top of Bear Canyon to Lamar Canyon (Powell
& Wauer 1990). Despite these efforts, no other populations were found. Viola guadalupensis is currently
categorized as a National Park Service Species of Concern, yet it appears to be in danger of extinction based
on its small population size and lack of significant habitat information. Powell and Wauer (1990:1) had
even commented that V. guadalupensis “is an immediate candidate for endangered status” for these very
reasons.
With this in mind, the Resource Management Office of GMNP has implemented a plan to collect seeds
and germinate them in a laboratory setting with the intentions of introducing V. guadalupensis to other
suitable locations within the park. The objective of this study was to locate suitable V. guadalupensis habitat
sites within GMNP, using a GIS-based habitat model generated from variables unique to the type locality,
and validate those locations with ground surveys.
METHODS
Study Area.—Our study was conducted within the 34,971 ha of GMNP, Culberson County, TX. The Gua-
dalupe Mountain range is a unique biological sky island consisting of Chihuahuan Desert vegetation (Agave,

mountain range of the Chihuahuan Desert is the past limestone uplift in the SECH United States,
formed 250 million years ago by an ancient reef system (Murphy 1984). Mountain summits excee d heights
of 2,600 m, shadowing deep canyon systems containing a variety of mountain springs. A 19-year average
of temperature and precipitation collected at the 2,455-m elevation automated weather station documented
average winter lows of -1.7?C, average summer highs of 23.9?C, and average annual precipitation of 45.0
cm (National Park Service 2005).
Monitoring the type locality.—The condition of the type locality was monitored on 26 May 2006.
We compared the counts of individual V. guadalupensis plants to a detailed line drawing of individual V.
guadalupensis plant locations and numbers produced by the Guadalupe Mountains Resource Management
Specialist during inventories conducted in 2001, 2002, and 2004. To avoid over estimating the population
size, individual plants were conservatively tallied and then averaged between counts for consensus.
GIS model development.—Based on the fact that V. guadalupensis had not been observed by park
staff or researchers in any of the mesic regions surveyed within the park, we speculated that this species
may have specific topographic habitat preferences that include 1) elevations with overall cooler, moister
conditions, 2) aspects with minimal hours of direct sunlight, and 3) vertical rock versus horizontal soil
substrate as indicated at the type locality. The National Park Service Intermountain Regional GIS Office, in

conjunction with GMNP, performed habitat modeling based on these variables to narrow the search areas
for potential habitat and suitable locations for establishing additional colonies.
GIS modeling was performed with ESRT's ArcMap Ver. 9.1 software (available from http://www.esri.com/
software/) incorporating the following parameters in order of priority: 1) elevation bands from 7,800 to 8,000
ft (feet were used for the ease of visually correlating potential sites to USGS topographic maps printed with
40-ft elevation contour intervals), 2) a northwest aspect range from 300 to 330 degrees, and 3) slopes >70
percent. Elevation, aspect, and slope were all derived from a 30-m digital elevation model (DEM) of GMNP
obtained from the National Park Service, Natural Resource GIS Data Store.
Using ESRI's ArcToolbox Reclassify tool, DEM cell values were used to separate elevation and aspect
into three classes (Class 1 = elevations between 3,500 and 7,800 ft and aspects O to 300 degrees, Class 2 =
elevations from 7,800 to 8,000 ft and aspects 300 to 330 degrees, and Class 3 = elevations > 8,000 ft and
aspects 330 to 360 degrees). The Raster Surface Slope tool was used to divide slope values into two classes
(Class 1 = slopes 0 to 7096 and Class 2 = slopes >70%). Each class of elevation, aspect, and slope was then
assigned a model value of 3, 2, 1, or 0. A model value of three was assigned to the elevation parameters met
by Class 3, while model values of 2 and 1 were assigned for the aspect and slope parameters in Class 2,
respectively. An assignment of 0 represented all other non-target cell values for every class.
All four model values were unioned together producing a model with seven categories from 0 to 6 dis-
played as a digital predictive habitat map. Category O displayed all non-target parameters; categories 1 and
2 displayed only slope and aspect, respectively. Category 3 displayed criteria for elevation or a combination
Mullet et al., GIS [ O ti DTN g m A T
of slope and aspect. Category 4 displayed areas where a combination of elevation and slope criteria were
met, while Category 5 req ted areas of both elevation and aspect. Finally, Category 6 displayed locations
where all three parameters of elevation, aspect, and slope were met (Table 1).
Model Validation.—Field validation surveys of predicted V. guadalupensis sites were conducted May
through July 2006. We used Universal Transverse Mercator (UTM) coordinates digitized in ArcMap to
find predicted sites where all three criteria were met (i.e. Gatto 6). A radius of 200 m was investigated
around each UTM location to compensate for any inacc es of positioning due to tellite geometry.
The specific characteristics used to determine suitable habitat of predicted eai in the field consisted
of north to northwest-facing rock walls with crevices and vegetation similar to that of the type locality, a
physically cooler ambient temperature, and shaded areas with sufficient canopy cover to protect the site
from direct sunlight. Rock faces <3 x 3 m were ruled out as insufficient space for colonization due to the
lack of potential dispersal of plants within the area.
RESULTS

recorded in 2006. Although no Ee were observed to be fl ing, several pl d

ings and photographs from previous inventories.
Model validation -- The model displayed 14 locations meeting all three criteria in Category 6. We investi-
gated a total of nine locations consisting of three sites near Guadalupe Peak (WGP, NGP1, and NGP2), two
near Bush Mountain (BMD1 and BMD2), one north of the Bowl (NOB), one near South McKittrick Canyon
(SMK), and two locations on Frijole Ridge. Five locations were omitted from investigation due to inacces-
sibility and by request of the GMNP Resource Management Office, therefore, no site codes were assigned
to these locations.
Two of the nine investigated locations predicted by the model on Frijole Ridge revealed populations
of V. guadalupensis. One of these locations was the type locality (designated VIGUL). The second location
revealed a new, isolated population of V. guadalupensis in a steep, slot-canyon drainage (approximately 2.1
to 2.4 m wide), on a 35 degree, northeast-facing limestone wall. The site (designated VIGU2) is located off
a plateau on the East Rim approximately 2 km northeast of the type locality.
We observed 25 individual V. guadalupensis plants at VIGU2 on 26 May 2006, growing largely in a
monoculture. Several V. guadalupensis plants were located approximately 1.5 m overhead, making an exact
count difficult. Although no seed capsules were observed on non-flowering plants, a number of violets still
possessed flowers. All violets had noticeably longer petioles and grew predominantly as individual plants
rather than in the mat clusters characteristic of violets at the type locality (VIGU1).
Associated plant species of VIGU2 included Valeriana texana, bedstraw (Galium sp.), and red alum-
root (Heuchera rubescens L.). Violets were shaded by the steep, canyon walls and a canopy of western hop-
hornbeam (Ostrya knowltonii Cov.) and P. strobiformis. Other surrounding vegetation consisted of mountain
spirea (Holodiscus dumosus Nutt.), Pseudotsuga menziesii, and Petrophytum caespitosum.
Three of the seven sites without violets (WGP, BMD2, and SMK) were considered to be suitable for
introduction upon comparison to the type locality. The remaining four locations (NGP1, NGP2, NOB, and
BMDI) were considered unsuitable, possessing sparse vegetation and fully exposed rock faces atypical of
either violet location.
Twenty-two percent of all survey sites predicted by the model had extant populations of V. guadalupensis.
Three of the nine sites (3396) were considered to be suitable sites for introduction. Overall, this model had
5696 accuracy for predicting suitable or existing V. guadalupensis habitat.
Potential locations for introduction.—The first site considered to be suitable was located around
WGP and appeared to be very similar to that of VIGU1. This site (designated WGPI) included a steep rock
g iesii and Ostrya knowltonii trees approximately 40 m down a

face, shaded by several small P

steep drainage. The ambient temperature was physically cooler in the early and late afternoon (1120 h
and 1619 h). This rock wall faces north to northwest with a number of crevices and associated vegetation
similar to VIGU1. The location is approximately 15 to 20 m long and 5 to 8 m tall with an elevation of ap-
proximately 2,500 m.
The second potential site (BMD2) possessed very tall and wide north- and west-facing cliff walls that
appeared to be suitable habitat, however, as investigation of the area progressed into the afternoon (1300
h), the rock walls were observed to be more exposed to direct sunlight than earlier that morning (1100 h)
as a result of sparse py cover. However, one rock wall, in particular, was considered suitable because it
met all desirable criteria outlined by the model and remained shaded by Pseudotsuga menziesii and Quercus
sp. at the time of investigation.
Finally, the third potential sit South McKittrick Canyon (SMK) possessed a number of small rock
walls (between 3 x 3 m and 5 x 5 m) with one single location (designated SMK2) significantly shaded by
Ostrya knowltonii, Pinus ponderosa, Pinus strobiformis, and Pseudotsuga menziesii. Data loggers, programmed
to record light intensity, relative humidity, and temperature, were placed at VIGU1, VIGU2, WGP1, BMD2,
and SMK2 for future comparison of microclimate data.
DISCUSSION
ifi of GIS-1 ] predicti deling.—The results of this study indicate two essential aspects
e understanding the sentando of this predictive model when compared to previous ground surveys and
the habitat requirements of V. guadalupensis. First, the GIS-based habitat model caed iiis type locality and
an additional population of V. guadalupensis along Frijole Ridge, as well as three potentially suitable habitats
for introduction west of this region. Since its discovery in 1990, extensive ground surveys of seemingly
suitable habitat have been unable to locate additional populations (Powell & Wauer 1990). Based on our
results, this study supports the relative usefulness of GIS-based habitat models for predicting the distribu-
tion of rare species consequently ee Se EE of random surveys.
Second, V. g pla; y t lopes, northerly aspects, and high elevations
on Frijole Ridge. Tes lts substantiate ou e that V. puadalupensls have specific topographic
habitat preferences toward the variables - to develop our model. It is important to consider the fact that
violets at VIGU2 were positioned on a northeast aspect rather than a northwestern aspect characteristic of
VIGU1. This observation might indicate that aspects ranging from 300 to 45 degrees (northwest to north-
east) may be a better representation of this species’ aspect preference than those strictly between 300 and
330 degrees.
Model efficacy.— Considering two out of the nine predicted locations represented violet populations,
while the remaining seven did not, suggests that 1) the variables used to develop the model were not spe-
cific enough to locate habitats strictly containing V. guadalupensis or 2) V. guadalupensis is restricted only to
Mullet et al., G1S-! | distributi fViol g lal i 683
these two locations on Frijole ridge and may have not had the opportunity to disperse to other areas. It is
also important to take into account that three of the five locations not ground-truthed in this study were
also located along Frijole Ridge. It is possible these locations may possess populations of V. guadalupensis.
Further investigation into these areas is suggested in order to allow for a more complete model evaluation
and to confirm the distribution of V. guadalupensis using this GIS-based habitat model.
Because the efficacy of a predictive model is dependant on the variables used to generate it, accurate
information of habitat requirements for a species is necessary for the devel t of an accurate predictive
model. Cherrill et al. (1995) stated that the rarity of a species greatly us a model's efficacy to predict
species-habitat distributions. Their model was generated from variables of known locations to predict rare
and common species compared to traditional field surveys. Their results found a higher rate of accuracy
for predicting common species than those of rare species. These results were dependent on the amount of
information available for each species (Cherrill et à 1995). Additional EE -habitat information or V.
guadalupensis (e.g., microhabitat conditions) will likely enabl g generate
model for predicting V. guadalupensis distribution and abundance.
Conservation and management.—Proper management of the two V. guadalupensis sites is vital for
its continued existence within the Guadalupe Mountains. The distance between VIGUI and VIGU2 (2 km)
suggests that gene flow between these populations is unlikely. Because the most promising mechanism of
seed dispersal across such distances is wind (Davies et al. 2004), this mechanism is improbable due to the
density of vegetation around VIGUI and the steep, narrow, rock walls surrounding VIGU2. These condi-
tions likely protect these areas from wind rather than ae to the use of wind- PRSE eed ia sae

for its conservation. mr we suggest that p— of violets into additional hould
representatives from both locations to improve genetic diversity within new areas to prevent an additional
bottleneck effect.
Although the locations of this species are far from human impact, several environmental factors may
threaten the persistence of these populations. The accumulation of ladder fuels within the park has cre-
ated conditions suitable for catastrophic wildfires along the East Rim. This could result in the burning of
V. d niin irn habitat or a reduction in the number of shade trees surrounding the area causing fatal heat
exposure (F. Armstrong, unpubl. report). Predation of leafs and seedpods by small mam-
nd. has been Na to occur at VIGUI (F. Armstrong 2002 and 2004, unpubl. field notes). Even
though there has been no direct observation of this activity, seed predation will likely affect the reproductive

success of individual plants, reducing overall genetic diversity and dispersal.
Continued monitoring of both V. guadalupensis sites and comparing the long-term microhabitat condi-
tions of known violet sites to potential introduction sites will provide a better understanding of specific
habitat requirements for introduction and habitat management. The two populations of violets, as well as
the three uninvestigated sites on Frijole Ridge, should also be considered during fire management planning
to prevent unfavorable conditions due to catastrophic wildfires along the East Rim.
The habitat model developed by the National RUE ala to predict potential V. guadalupensis habitat
has provided critical baseline data for additional i d research within GMNP. Due to the suc-
cess of finding an additional population and other MN sites for introduction, resource managers can
utilize this information for continuing plans to proliferate and conserve V. guadalupensis populations with
potential success.

INTRODUCTION
The Dead Horse Mountains (DH) of Big Bend National Park (BBNP) create a remote and forbidding view-
scape on the West Texas park's eastern skyline (Fig. 1). The rugged limestone escarpments offer no reliable
surface water, nor infrastructure allowing quick access to the interior, leading to claims of it as being un-
charted wilderness (Wood et al. 1999). These logistical challenges, in addition to rugged topography and
extreme climate, have left the area one of the least botanically understood areas in Texas and the northern
Chihuahuan Desert Region (CDR). Much collecting has taken place in the area over the past 100 years. The
height of early scholarly investigations came in the 1950s-1960s, and included a SRSU master's thesis by
Rogers dd a EEN E excellently cl terized field report by Wells (1965), and collections by numer-
Sul Ross State University (SRSU) botanist Barton Warnock. The largest coherent
body of collections was ade for a report to the Nature Conservancy (Amos and Giles 1992), which at the
time owned a part of the study area that is now part of the Texas Parks and Wildlife's Black Gap Wildlife
Management Área.
The majority of vouchers made through these efforts came from more easily-accessible areas, near
roads and trails peripheral to the end DE ER range, without widely sampling the range of niche habitats
existing in the area. Despite a rat! torical interest in this area, no overall floristic characterization
has been made for the Dead Horse. Several lists of local flora exist, including more than one in use for Big
Bend National Park; however these are based on sightings, literature reports and, to an unknown degree,
herbarium specimens (Mahler 1971; National Park Service 1996; Louie 1996; Clelland 2001; Worthington
2001; Alex et al. 2006).
A floristic analysis of the Dead Horse will create an important context for Big Bend regional floristics.
The DH are located in the Trans-Pecos Mountains and Basins vegetational area (Hatch et al. 1990) but
phytogeographic connections have been noted with other Texas floristic areas including the High Plains,
Rolling Plains, Edwards SECH and the South Texas Plains, also known as the Tamaulipan Thornscrub
region (Powell 2000). C | to more northerly vegetational areas are evidenced by the populations of
aspen (Populus tremuloides), Douglas-fir (Pseudotsuga menziesii), and other Rocky Mountain species growing
well south of their normal distributions. Floristic links also reach south to the Sierra Madre Oriental and
Occidental, expanding to the greater CDR of Mexico (Larke 1989). The graminoid flora even has an affinity
to the Great Plains grasslands (Powell 2000; Christie 2006). Because there are so many regions intergrading
in the local area, there is high potential in the study area to discover species out of their expected ranges.
Furthermore, the DH is topographically complex and the resulting microclimates may harbor species new
to science. Already the area shelters several little-known species: Andrachne arida is known from only a few
localities in the CDR and has not been seen in the DH since the 1960s, while the purported Dead Horse
endemic Hedyotis pooleana has not been observed since the original 1985 collection. Other species are as-
sumed to occur in the study area based on their known habitat, but are not well understood, being known
only from a few collections in a restricted area. One such example is Bouteloua kayi; previous to this study
it was not known to occur in the study area but was discovered during the current work.
s environmental complexity, in Boti topography and regional climate regimes, no doubt has helped
f the CDR, but instead of being widespread, endemics are mostly
ely distributed (Brown 1994). indeed: in Trans-Pecos Texas, Brewster County tallies the highest numbers
of endemic (TAM-BWG 2007) and rare plant species (Alex et al. 2006; Poole et al. 2007). Often, however,
species of concern are little known beyond data taken at their original collection site. Thus, targeted field
studies in Chihuahuan Desert areas like the Dead Horse have a high potential for new floristic discoveries.
The main objective of this project was to create a collective body of work describing the floral composi-
tion of the DH. Goals to accomplish this objective included: (1) developing an annotated flora for the study
area through documenting existing voucher specimens in regional herbaria, and through new collections
from a wide variety of underrepresented areas and habitat niches in the range; (2) gaining more knowledge
about little-known species that occur in the range, includi ies known regionally but not yet recorded

Site Description
The DH are located in the Big Bend region of western Texas, in Me ROSE County about 80 mi south
of the town of Alpine (Figs. 1, 2). The study area boundary starts in t tern part of the national park
at Dog Canyon, continues south along the western foothills of the DH, and extends east into a portion of
Texas Parks and Wildlife's Black Gap Wildlife Management Area (BGWMA), including a few parcels of private
ranchland (Fig. 3). The Rio Grande marks the southern limit. The DH are a smaller, northern extension of
the impressive Sierra del Carmen of northern Mexico, exhil imilar physical characteristics: northwest-
trending ridges alternating with alluvial basins, and generally — arid, rocky terrain. Extending 31.5
mi (51 km) N/S and an average of 8.5 mi (14 km) E/W, the study area covers approximately 176,800 acres
(71,548 ha; 276 mi?, 715 km?) and ranges in elevation from 1800 ft (549 m) at the Rio Grande to 5840 ft
(1780 m) at Sue Peaks in the heart of the range.
The only major physical feature that trends east-west in the study area besides Boquillas Canyon along
the Rio Grande is the 14-mile-iong Ge 5 km) EE SE that bisects the DH. There are l major
drainages in the study area, but tl Any PISCIS Ms occurs usually
flows overland into the dry arroyos, Sie powerful but temporary floods d Rio Grande.
Away from the river, surface water is found only unreliably in tinajas, i.e., stone GE eroded usually out
of arroyo or canyon beds with bedrock outcrops. The study area experiences hot summers and cool-to-cold
winters. The average annual high is 85?F while the low averages 53?F with an average annual maximum of
100? F/38? C and minimum of 33? F/1? C. Large diurnal temperature ranges are common, with a mean of
about 32? F/0? C and a maximum of about 50? F/10? C. EEN peaks between May and October, the
10 in/25 cm yearly average falling usually as late afternoon t that range in intensity and often
create hail (temperature data from National Park Service, Big Bend National Park, unpublished data).
The DH are composed primarily of lower Cretaceous limestone deposited in a deep sea environment
ca. 180 mya. As the area was close to the shoreline of the great interior sea, and as sea levels fluctuated,
some shales and clays were deposited, reflecting the changing environment. During the Cenozoic (ca. 30
mya), massive blocks of Del Carmen and Santa Elena Limestone were uplifted and tilted along fault lines,
resulting in the basin and range morphology seen today: gradual western slopes and steeper escarpments
to the east, ge with alluvial basins in between (Maxwell 1979). DH soils are mostly shallow with a
high pene f rock fragments (mostly calcium carbonate). Boc nen are frequent and most slopes
are steep. There are small, localized areas on alluvial upland ] ghtly deeper, while deep,
loamy soils can be found in some basins and near the Rio Gránde. The highest elev STE have soil darker in
color because of its high organic content and may be moist more often than dry (Cochran & Rives 1985).
Human History and Disturbance Regimes
People were living in the Big Bend area as early as the late Paleo-Indian period (12,000—6500 BC) and there
is abundant evidence of habitation in the Dead Horse dating from the Archaic period (6500 BC-ca. 100 AD;
Alex 1990). The periphery of the DH was most probably used as a travel corridor throughout history until
more permanent settlement occurred in the Historic era (1535 AD— Pesos after the threat from hostile
Indians was removed, panne and EE activities increased subst ly (Tyler 1975).

most damaging and far-reaching would likely be the i d distribution and dominance of invasive plant
species. Tamarix spp. and Arundo donax have expanded their range along the Rio Grande, creating miles and
miles of dense thickets lining the riverbanks. Pennisetum ciliare is well established in the lower elevations of
BBNP, including the extreme southern end of the study area. However, it is not as dense as it has become in
other low-elevation areas, perhaps being held in check by other non-native species, burros and horses. The
livestock enter the park from Mexico, trampling vegetation and breaking up biological crusts, increasing
the erosion potential in many places along the river corridor.
Fire may be a significant natural factor driving the study area ecology, creating the characteristic
patchiness of higher elevation vegetation. Human-caused fires are limited to the developed areas but the
interior puns are mainly lightning strikes, burning an individual yucen in more DATED rocky areas, but
nages or at higher elevations wl denser. Henrickson
and Johnston (198 6) suggest that the unique Yucca Woodland community at higher CDR elevations may be
maintained by fire, favoring the semi-succulent monocots over more woody species. There has been little
suppression effort in the DH, so current states should be considered normal.

there exist excellent overviews p basic and detailed — structure (Morafka 1977; Henrickson &
Johnston 1986, 2004; Brown 1994; Powell & Hilsenbeck 1995). Descriptions in several local floras (Rogers
1964; Butterwick & Strong 1976; Amos & Giles 1992; Hardy 1997) demonstrate the degree of local diver-
sity possible within hierarchies created by the above publications. Beyond a large-scale tendency towards
homogeneity (Brown 1994), the DH and larger CDR have basic plant-community types that intergrade
and change in abundance and dominance in response to the complex physiography. Perhaps Whittaker,
as quoted in Takhtajan (1986), has offered the best explanation for general Chihuahuan Desert vegetation
patterns: in warm, semi-arid deserts there is no clear convergence of dominant forms as can be found in
cool semi-deserts. Warm deserts may be too dry to support arborescent life-forms or consistent canopy
cover. However a diversity of non-arborescent growth is supported in pockets of higher moisture availability,
maintained by the right combination of aspect, slope, elevation, and substrate. Larger plants, such as shrubs
and Yucca spp., can also create special microclimates. Many species take advantage of the shade and wind
protection that these larger nurse plants provide. This could be considered the canopy of the CDR—low
and discontinuous, but eeng

Based on a consolidated version of Plumb's (1991, ee vegetation maps, Lechuguilla i covers e 4%
of the study area. This vegetation type includes Agave lechu guilla, Opuntia spp., Eu phorb 1, and
many species of grasses. AOS ees important in the study area is the High Desert Grascland vegetation

and Big Bend National Park (BIBE). Sheet-by-sheet searches were conducted at SRSC and BGWMA.
Fenstermacher et al., Vascular flora of the Dead Horse Mountains 695
All species found in flower were collected during every trip. Collection of rare species or plants of
uncertain identity and/or distribution was guided by BBNP protocol: no more than 10% of the individuals
of any viable reproductive population of a rare plant were harvested. Most collecting was done within the
National Park, due to easier and quicker access to more areas. Access to the study area was mainly on foot
using cross-country navigation but two rough dirt roads and two maintained trails did provide effective
access to more interior areas of the tange: Two river trips allowed limited Md access. A few extended,
overnight trips were enabled by water je ly transported into tl try by NPS trail crew
personnel and packstock.
Sampling areas were chosen based on intricacy of topography such as deep and/or sinuous canyons,
unvisited but potentially unique areas such as the higher peaks, and otherwise intriguing spots identified
on USGS 1:24,000 topographic maps. Search methodology was a directed meander (Goff et al. 1982) at
each locality visited, focusing on promising microhabitats and moving from patch to patch as the observ-
able species diversity was documented. Field notes and resulting label data included collection location,
habitat, habit, description of notable plant features, relative abundance, and associated species. UTM coor-
dinates were taken on site or approximated post-field using digital elevation model data through ArcView
3.2. Specimens were identified using multiple sources, including Correll and Johnston (1970), Warnock
(1970, 1974, 1977), Flora of North America Poaceae and Asteraceae volumes (FNA 2003b, 2006, 2007),
Powell (1998, 2000), Yarborough and Powell (2002), Turner et al. (2003), and Powell and Weedin (2004).
Specimens were determined by B.L. Turner of Pu LL vo A. ee Powell of SRSC. The atlas of Turner
et al. (2003) was the pr imary source for an ti l data, and two online sources (ITIS
2007, MBG 2007) were followed for author ER b vee of the Vascular Plants of Texas (Correll
& Johnston 1970) provided the fund tal taxon g for this work. However, numerous other
sources were utilized for the most up-to-date t ic i tations, most notably Powell (in prep.) and
Powell et al. Gn ms.) for non-woody vascular species and — the Flora of North America for Poaceae and
Asteraceae treatments (FNA 2003b, 2006, 2007), and Powell and Weedin (2004) for the Cactaceae. Voucher
specimens made during this project deposited at SRSC; selected duplicates were sent to BIBE, TEX-LL,
and BRIT.
RESULTS AND DISCUSSION
Between August 2003 and See SE a p of 49 days and approximately 400 hours were spent in
the field. The 1549 voucher those three years, plus four observations without vouch-
ers, represent 84 families, 283 genera, and 490 p dee totaling 493 taxa at or below the species level. The
herbaria search revealed an additional seven families, 58 genera, and 173 species (178 taxa) that were not
encountered during the current study. Similarly, the current study documented a itiona families,
45 genera, and 120 species (121 taxa) beyond the historical baseline found in the herbaria search. Fifty-five
of those additional 120 species were new records for the DH, representing a 1096 increase in known taxa.
Another 65 species (67 taxa), though not previously represented by vouchers, were common and suspected
to occur and thus not considered novel records. In sum, the total known flora of the DH to date consists of
91 families, 344 genera, and 662 species (671 total taxa).
The Asteraceae is the most prominent family in the DH, tallying 80 species. Other important families
include the Poaceae (75 species), Fabaceae (52 species), Euphorbiaceae (34 species), and Cactaceae (31 spe-
cies). The eight most species-rich families comprise 5096 of the flora while 24 families are represented by a
single taxon. The most abundant genera represented in the DH are Chama d Dalea at 13 species each
A taxonomic breakdown of species found in the DH shows that sadios make up the largest propor-
tion of the flora at 78.9% (Table 1). Gymnosperms comprise the smallest portion of the flora after monocots
and the ferns and fern allies. Perennial herbs were the most abundant life form encountered, followed by
annual herbs, shrubs, subshrubs, succulents, vines, and trees (Table 2). The annotated list of species found
in the DH provides the following information for each taxon: native status, new records, rare species status

Herbarium search
It is certain that more DH collections exist in regional herbaria. The collections of one botanist who made
significant collections in the BGWMA reside at BRIT, but are not electronically databased. Unfortunately,
time and funding constraints precluded a sheet-by-sheet search of that institution for this project. Digital
records are a boon to this type of research; however, when in existence they should not be assumed to be
complete or entirely accurate. For example, in researching the holdi t SAT, an onli h of the Floral
Consortium of Texas website revealed 64 vouchers, but an onsite secs of SAT’s internal digital database
resulted in 245 collections, with only three overlapping with the consortium’s results. Added to that dis-
crepancy is the fact that not all of the holdings at TEX-LL are included in their online searchable database.
Given that that is the main repository in the state, there is a high probability that many DH vouchers were
not accounted for through the herbaria search.
Compras
f collection efforts in the study area, including those during the past 15 years, there was
a significant rise in peda found, without any evident leveling of return for effort. This is to be expected,
with much new territory having been covered in more recent years by the Amos survey of Brushy Canyon
in addition to the current project. However, the return of new species per year of effort during the course of
this study began to taper off and fewer new species were found than remained unseen from the historical
Fenstermacher et al., Vascular flora of the Dead Horse Mountains 607
baseline. S historicall llected were not revisited, such as tl inland riparian habitats of the
1
Rio Grande Village area, he species may still be extant or perhaps extirpated due to the ging nature
of the river corridor. More localized examination of return for effort tells a mixed story: after three visits to
the same area of mixed, mid-elevation habitat, there was no reduction of return for effort. However, after
two SC to the high-elevation Sue Peaks environment, the return of new species decreased by about 50%.
he differences may lie in the types of habitat visited, but one must also keep in mind the vagaries of desert
flora—life strategies built around responses to ephemeral rain, general seasonal/temperature restrictions,
ane even bi Enn cycles, all serve to limit the flora prem at any given time. Certainly more species await
in the study area; collectio hout most of the Dead Horse range, but some
interior locations such as Margaret Basin, the upper Strawhouse trail, the eastern end of Telephone Canyon,
and areas interior to Boquillas Canyon remain under collected. Despite this, however, it seems clear that the
majority of the flora has been documented.
Vegetation Patterns
Henrickson and Johnston (1986) comment on the high degree of intergradation between vegetation types
in the CDR and the difficulty of placing many areas into an exact classification. This can result in many

is the only vegetation type that occurs in association with permanently flowing water and mainly occurs
within Boquillas Canyon: (Fig. te), ELA the slightly inland, developed areas around RGV have significant
riparian habitats that rsity ofthe st study area. Although few plants are seen throughout
the range at all elevations, Ger ECH and Aristida spp. are possibly the most ubiquitous.
Mixed Desert Scrub.—The psc vegetation type extends from the lowest elevations to about 4000 ft
(1220 m), nearing the higher plateaus of the Dead Horse. The lowest elevati ] flattest terrain of the park
are dominate d by Larrea tridentata, which is seen most often on low, foothill approaches and interior basins
of the DH. Intermingling at lower elevations are Opuntia aggeria and O. grahamii, Parthenium incanum, Nama
hispidum, and Acacia neovernicosa. Flourensia cernua is often cited as being important, even co-dominant,

I I d l include: Tiquilia greggii, Prosopis
STEEN Condalia sp., Zizipl btusifolia, Buddlei iifolia, I hyll 1L. candidum, Vigui-
era stenoloba, and Chrysactinia mexicana. Iutergrading with jower-elevarian species is Dasylirion leiophyllum,
which begins to occur as low as oo ft (1066 m), but extends to the oe elevations of the range. Dense
stands of the rhizomatous Ag illa and Hectia texensis occur sporad dically and d usually include more
obvious occurrences of the a common species: Selaginella lepidophylla, Selaginella wrightii, Astrolepis
spp., Argyrochosma microphylla, Calliandra iselyi, and Opuntia rufida. Biological soil crusts of varying degrees
of development occur in most inter-rock spaces, harboring various species of cyanobacteria, lichens, and in
the right environment even mosses.
Desert Arroyo.—Many of the general psc species overlap into the dry watercourses intersecting the
region; the two xeric-riparian vegetation types are generally distinguishable according to the amount of
moisture available. par, or Sandy Arroyo Scrub as named by Henricl and Johnston (1986), occurs in more
open, low-elevation drainages incised into the desert flats. TI gi ich with perennial plants, which

often grow into impenetrable thorny thickets across the wash. Fallugia paradoxa and Brickellia laciniata are
commonly present in the wash cobbles of larger drainages, while Prosopis glandulosa, Guaiacum angus tifolium,
Forestiera angustifolia, Celtis pallida, Lycium berlandieri, and Porophyllum scoparium are common throughout.
Desert Canyon.—In rockier habitats, larger drainages, and within canyons that provide partial shade,
the pca vegetation type includes additional species such as Berberis trifoliolata, Fraxinus greggii, Diospyros
texana, Eysenhardtia texana, vids inii deg SPP. Acacia roemeriana, Schaefferia cuneifolia, Rhus
virens, Tecoma stans, Clematis drummon , and Maurandya antirrhiniflora. Common wash-
associate grasses are Bothriochloa laguroides, Heteropogon contortus, Setaria ina and Aristida spp. More
water-dependent species such as Ung E 1 and Chilopsis linearis occur infrequently, restricted to the
largest drainages.
Juglans mi pa is not a typical DH species within BBNP; it was seen only once in the National Park
at the north end of the range, but as reported by Amos and Giles (1992), it was observed during the cur-
rent study to be much more dominant in BGWMAS Brushy Canyon. In the same Amos and Giles (1992)
report, Cercis canadensis var. mexicana was listed as a dominant in Brushy Canyon, it was not observed in
the National Park portion of the DH. Canyon walls throughout the range provide a relatively consistent but
limited habitat for cliff-dwelling species including Cirsium turneri, Perityle aglossa, and Perityle bisetosa var.
scalaris.
Rio Grande Riparian Corridor.—A more traditional riparian woodland M ed SE exists nd
along the Rio Grande, e the consistent water table can support native speci hasP
Salix spp., Bacc licifolia, Pl ites australis, and tl t d and invasive Arundo dona "€ Dude
spp. Á a solitary individus Ba more drenan genera (e.g., Salix, Baccharis, and Tamarix) occur
in at least one other place in the DH interior: above Ernst Tinaja, where their water-hungry roots may have
found a perched water table. Also important along the Rio Grande are Acacia farnesiana, Nicotiana glauca,
Prosopis glandulosa, and Chilopsis linearis.
The major, non-native species have altered and will continue to alter the riparian landscape. Thickets
of cane with abundantly dense rhizomes have solidified the river banks, channelizing the watercourse.
This creates, in many cases, an irreversible cycle: the channel concentrates the river flow, which increases
its velocity and thus erosive power, which, in turn, creates a deeper channel that does not allow flooding
over its banks as easily as before. With over-bank flooding decreased due to channelization and a generally
reduced flow/flood cycle due to upstream dams, dense canopies of Arundo donax and Tamarix spp. are al-
lowed to establish, precluding the formation of native Salix spp. and Populus spp. bosques (Howe & Knopf
1991, Bell 1997).
Sotol-Yucca Grassland.—Found on the higher elevation slopes and plateaus to the highest peaks, sY is
the dominant vegetation above psc. The vegetational boundary seems to occur , atleast on the western side of
the range, at around 5000 ft (1524 m), where the steep western slopes top out to form a main central plateau
within the DH range. Stuarts Peak, though slightly lower at 4800 ft (1463 m), should also be included, due
to its many unique Gen characteristics, o a eios lichen flora and, in the DH, the only known
populations of two tl I ted vegetation— Philadelphus microphyllus

terminology. The DH do seem to have a Been: shrub ne BEES Dy Fi dps leiophyllum,

visual member of the svc creating, along with the Dasylirion leiophyllum, large masses of thick vegetation,
standing in some places almost head high.
Fenstermacher et al., Vascular flora of the Dead Horse Mountains 699
Common plants associated with the syc of the DH include Yucca torreyi, Yucca thompsoniana, Nolina
erumpens, Fouquieria splendens, Parthenium argentatum, Bouchea spathulata, Leucophyllum spp., Bernardia
obovata, Vauquelinia angustifolia, Mortonia scabrella, Zinnia acerosa, Coryphantha tuberculosa var. tuberculosa,
Coryphantha echinus, Neolloydia conoidea, Epithelantha macromeris, Bouteloua curtipendula, Aristida spp., En-

True grasslands, though included in reviews of CDR vegetation types, are not functionally a part of the
DH t. Areas that are clearly dominated by graminoids without a significant shrub tare

northern Big Bend. In the DH, grasses are important components of the shrubby slopes and higher plateaus,
and at higher elevations, a oe dime m are important components of the vast grama grasslands to the
north do occur. However, small areas dominate d by grasses occur only on the scale of remnant patches rather
than functional ecosystems; they are not dense or contiguous enough, nor dominated enough by the typical
grassland species Bouteloua eriopoda and Bouteloua gracilis, to be considered a true grassland. This seems to
follow a general trend of grama grasslands being established on igneous soils, whereas limestone substrates
in similar conditions will support only desert-scrub assemblages (Henrickson & Johnston 1986).
Chaparral.—Small pockets of shrub thickets, or cup, occur within the syc on plateaus and eastern
slopes associated with the high EE M the Sue Peaks area. Small and sometimes dense clumps of
Quercus pungens, some Q ind Quercus grisea, Cercocarpus glaberoides, Berberis trifoliolata and
Rhus virens associate with large Dasylirion eia anid Nolina erumpens, all overtopped by the occasional
but conspicuous Yucca faxoniana. Expected but less frequently seen species include Fraxinus greggii, Garrya
ovata, Ptelea trifoliolata, and Muhlenbergia parviglumis. Oaks and other more mesic species occur also at the
highest summits and in more protected parts of drainages, even in steep drainages and lower elevations of
the western slopes. These micro-niche species include Malacomeles denticulata, Quercus pungens, Fendlera
falcata, Fraxinus greggii, Prunus havardii, and Ina ida spp.
Junipers, including Juni huil hotii, occur sporadically on the high plateaus
amongst the chaparral clumps and, very panes i in ieee, -bwendevatin canyons. Pinyon pines are rare,
documented only at a few eastern-slope locations. These species are probably relicts from the previously
extensive juniper-pinyon-oak woodland covering the region between 22,000 and 11,000 years ago. The
main pine of the DH is Pinus remota, a limestone specialist (Powell 1998). Once more widespread, Pinus
remota in the Trans-Pecos is limited to isolated pockets, being more abundant on the Edwards Plateau and
in Mexico. Records of Pinus cembroides in the DH are unusual; it is a higher-elevation taxon, although the
two species are known to occur to BERE Remum in the Big Bend region (Powell 1998).
Unique Habitats.—Several encountered during the course of the study; only the
sand dunes at the mouth of Boule Canyon have been explored rather thoroughly. Though not extensive
enough to support a full representation of Henrickson and Johnston's (1986) Sand Dune Scrub vegetation
type, they have been well botanized and do provide a unique habitat for a few species including the rare
Chamaesyce golondrina and the sand-loving species Heliotropium convolvulaceum, Corispermum americanum,
and Dalea terminalis. Several other unusual vegetative would no doubt profit from further examination.
An isolated bottomland of Pleuraphis mutica covers the western edge of Ernst Basin, in stark contrast
to the sparsely vegetated, more elevated flats over the rest of the basin. This tobosa grassland area may rep-
resent a small inclusion of Tornillo soils, which was previously unknown in the DH and is interesting not
only because Pleuraphis mutica occurs in distinctly limited areas of BBNP, but because several other species
were collected only there: Malvella leprosa, Leptochloa panicea, Chamaesyce serpens, and the Texas endemic
Lycium puberulum var. berberioides. The possibility of similar habitats, i.e., the existence of Tornillo soils, in
other large basins in the DH should be explored, in particular at the northern end of the Ore Terminal trail,
in Margaret Basin, and along the Strawhouse trail.
The vegetation in a high saddle (5300 ft, 1615 m) just north and west of Sue Peaks was completely
different from the immediate, Rosetófilo-type surrounding community. The soil was finer, deeper, and less
700 t tani i Texas 2(1)
rocky than the surroundings; old wire, pieces of wood, and prehistoric lithic scatter including point bases
and partial tools was found on the ground surface. Many plant species found there are reminiscent of the
tobosa grassland area north of the bid Mountains in the Harte Ranch area of BBNP, Pleuraphis mutica,
Panicum obtusum, and Hoff in particular. Other species diia ER ES inique com-

The other habitats deserving of more attention are at the highest elevations, especially Sue Peaks and
Stuarts Peak. Each has different characteristics making them interesting. Stuarts Peak is a rather narrow
ridge, with not much area formi ng the actual summit However, many plants li | there were surprising
to find in such a seemingly arid location, including Achnatherum curvifolium and Philadelphus microphyllus.
The lichen and moss flora on the summit ridge was impressive in its diversity, which was not observed to
the same extent anywhere else in the study area. Also notable was that the summit ridge was one of the few
places encountered where the cactus Neolloydia conoidea was growing densely enough as to preclude non-
damaging travel.
The Sue Peaks area exhibits a well developed cup community with shrub oaks being very common in
EIA mane DH Gegen area. The peaks themselves are rather bare of large shrubs, those being relegated to
d ledges. Several species, ome only in this area, were observed and collected on
hatami6um
a trip following significant rains in the area: revicaulis, Ipomoea costellata, N i
Dichromanthus cinnabarinus, and Mirabilis linearis. These species, in addition to others known only from the
peaks or the surrounding area including Asplenium resiliens, Asclepias sperryi, Quercus mohriana, Fraxinus
cuspidata, Quercus laceyi, and Pinus remota, indicate that conditions on the whole are relatively mesic and
that under favorable conditions, additional unique species may be in evidence.
Non-natives, Range Extensions, Rare Taxa, Notable Collections
Non-native species constitute a small part of the DH flora. The USDA considers 24 species collected in the
DH as exotic (USDA 2007). Six of those species are considered invasive, and three are state-listed noxious
weeds: Arundo donax, Tamarix aphylla, and Tamarix chinensis (PTI 2006). Significantly, Pennisetum ciliare, an
introduced grass from Africa, is not among the Texas-listed invasives; however, it is a demonstrated threat
to native ecosystems throughout the southwest (e.g., TNC 2005) and is listed by the state of Arizona as a
noxious weed (AZDA 2005). The fact that it is widely planted in Texas and northern Mexico as a range grass
perhaps makes its listing unlikely. Eragrostis lehmanniana is a well-known invasive in the desert southwest,
but its presence in the study area appeared to be minimal outside of the river corridor. It seems to require
more moisture than is reliably present in the majority of the range, with isolated plants being found near
an old header dam and in shady or sandy areas of large drainages. Overall, non-native species constitute
3.6% of the DH flora.
Eleven species found in the DH are endemic to Texas, according to the Texas A&M Bioinformatics
Working Group and updated taxonomic and distribution information (TAM-BWG 2006). The occurrence
of Matelea sagittifolia in Brewster County is not currently reflected on the referenced website, but it was col-
lected during the present study and also during a recent survey of the Lone Mountain area of BBNP (Fen-
stermacher et al. 2006). Lycium puberulum var. berberioides is also not listed by the Bioinformatics Working
Group as occurring in the county but should be; it has been a known dd a the NE flora for some
time (Powell 1998). Hedyotis pooleana, though included in this DH-endemi ; i t listed
by the Bioinformatics Working Group, perhaps due t nsensus its — (Turner 1995,
1997; Terrell 1996, 2001). Endemic species discount for 1.796 of the DH flora.
Many noteworthy collections were made during the study period. The Wildlife Diversity Program of
TPWD, in conjunction with the Texas Conservation Data Center of the Nature EECHER of Texas, tracks
seventeen rare spectes d were collected in the DH (TPWD 2006). Several of tl ollecte
new locations. Bout ly known only from one location east of the DH but it was found to
be one of the dominant grasses at eben elevations near Sue Peaks. In the mid 1980s, Hedyotis pooleana was
first collected at one locality in the DH and named as a new species. Subsequently it was not seen until the
Fenstermacher et al., Vascular flora of the Dead Horse Mountains 701
present study during which it was found throughout the majority of the range in higher-elevation bedrock
exposures.
Andrachne arida was last collected in the DH in the 1960s, and during the study period it was relocated
in the general vicinity of the historical collections. One small population of the diminutive legume Senna
ripleyana was discovered, clarifying its status as having remained extant north of the international border
since its last documented collection in northern Brewster County in the 1940s. Another historically col-
lected taxon Sed ifolium was encountered in shallow soil pockets on the DH plateau. Regionally it was
previously known Bg one collection in the limestone mountains of northern Brewster County (Warnock
1977) and has been recently observed on hilltops of the Cox and Guadalupe ranches, about 15 mi (24 km)
west of Sanderson (M. Terry pers. observ.).
One taxon, a member of the genus Galactia, as yet is not identified to the specific level. It does not fit
descriptions of known Texan taxa (B. Turner pers. comm.) and awaits review when appropriate herbarium
specimens become available. Populations have been found in several southern DH locations and the plant
was encountered more commonly near the Rio Grande within side drainages of Boquillas Canyon. It is a
sprawling, procumbent perennial from a central taproot, often growing vine-like within larger, surrounding
vegetation. It has dense, silvery pubescence on all vegetative parts but is more pronounced on the leaves,
those having prominent under-surface veins. The flowers are pink, the banner exhibits a green-yellow base,
and the petals turn a deep blue-purple upon dessication.
New to the United States, the Mexican taxon Seymeria falcata var. falcata was collected north of the
border originally in 1994 (MT 137 SRSC), but it was not recognized as such mu Ene Ve the current
study spurred a review of previous collections of its more widespread
2006).
Eight species were newly recorded for Brewster County, according to Turner et al. (2003) and known
herbarium specimens: Achnatherum curvifolium, Atriplex rosea, Argemone mexicana, Hedeoma serpyllifolia,
Matelea sagittifolia, Maurandya wislizeni, Nama dichotomum, and Rumex maritimus. Three of these species,
Atriplex rosea, Arg mexicana, and Maurandya wislizeni, were collected by NPS staff in conjunction with
the restoration site at the mouth of Boquillas Canyon.
Many of the newly collected species for the DH are taxa that normally occur in much less arid condi-
tions at the highest elevations in the Trans-Pecos. Achnatherum curvifolium is a C3 grass previously known
from a restricted range in the Guadalupe Mountains of Texas and New Mexico (Powell 2000), and the nearby
Delaware Mountains (Worthington 24663 SRSC). de EH is deeg elevation-restricted species,
previously known from the Hos pa 1G I ibution ranges from Colorado
down through the Mexican highl into t te South America (Correll and Johnston 1970; Turner
et al. 2003). In addition to the sparsely occurring Ee taxa of Juniperus and Pinus, several other species were
found whose presence was not expected in such relatively arid conditions: Philadelphus microphyllus, and
several other C3 grasses Achnatherum eminens, Achnatherum lobatum, Hesperostipa neomexicana, and Melica
montezumae. The DH are virtually the only area in the park where the giant dagger, Yucca faxoniana, occurs.
Interesting observations were made of dog cholla (Opuntia spp.) populations from the southern end of
the study area. Dog cholla species of the southern Big Bend, most as part of the Opuntia schottii complex,
have been of taxonomic interest for some time (Anthony 1956). The most recent attention in the literature
documented that a long-believed hybrid, purportedly a cross between the tetraploids Opuntia grahamii and
O. schottii, was finally determined to be a distinct species, Opuntia aggeria, based on morphology and its
diploid nature (Ralston 1987, Ralston and Hilsenbeck 1989). During the current study, however, several
observations and collections provide impetus for a fresh look a the taxonomy of southern Big Bend dog chol-
las: (1) a triploid hybrid was documented in el Ernst eis area aa 635 SRSU; parents undetermined); (2)
Diploid individuals with widely varying her 640, 1574 SRSC) may indicate that
Opuntia aggeria has an even broader species content awe prea described by Ralston and Hilsenbeck
(1989); (3) a tetraploid cholla was documented at Ernst Tinaja (Fenstermacher 691 BIBE) with morphology
702 ) t tanical Institute of Texas 2(1)
dissimilar to both Opuntia schottii and O. grahamii, possibly suggesting a larger distribution of Opuntia
densispina in the Big Bend than previously surmised (Ralston and Hilsenbeck 1992, Powell and Weedin
2004); (4) all collections and individuals examined of Opuntia grahamii were sterile, effectively producing
no pollen (J. Fenstermacher unpub. data). These findings suggest that the taxonomy of the Opuntia schottii
complex is not completely understood; more data from Mexican populations may allow further resolution
of the problem.
Floristic Analysis and Phytogeographic Connections
As a portion of Big Bend National Park, the flora of the DH is 5496 of the park's listed total (NPS 1996) yet is
found only on 2496 of the land area. Clearly, this eastern side of the national park with its riverine and high-
elevation habitats is an important source of area id RA Manes with regional floras are hampered
by their mostly out-of-date checklists, but exploring hips to peripheral floristi d the larger
southwest region is possible. One of clearest results of analyzing the DH flora is that while the Asteraceae is
the most dominant family E the Southwestern flora (McLaughlin 1986), the Poaceae is co-dominant with
Asteraceae in the DH and ot thern Big Bend fl (Fenstermacher 2007). This suggests the connection
to the Great Plains grasslands, moving into Texas through the High and Rolling Plains vegetation zones of
the Panhandle region. The connection has also been quantitatively demonstrated by Christie (2006).
The Fabaceae is also important in the Southwest, but more important locally in the DH. This family
comprises a larger percentage of the species of the SW flora than in the DH, yet the DH have more fabaceous
species (52) than the average for SW floras (28). In fact, only five DH genera make the Southwestern flora's
top-twenty list, and they do not include Dalea, one of the two dominant genera of the DH. The local im-
Poen of the Fabaceae, in addition to the many other resident thornscrub species like Aloysia gratissima,
ophyllum spp., may indicate the importance of the Tamaulipan Thornscrub flora
(WWF 2001). Indeed, for the few Trans-Pecos individuals of the more Tamaulipan species, Acacia berland-
ieri, Croton torreyi, and Karwinskia humboltiana, the Rio Grande corridor has most likely provided a conduit
of limited habitat that enabled these species to extend their distributions upriver into generally more arid
surroundings.
These connections to peripheral vegetational areas suggest that the CDR, and by extension the DH,
are not simple extensions of the Sonoran region, as Cronquist suggests (1982). Rzedowski (1973) notes that
both desert areas have several endemic genera (21 Sonoran, 16 CDR), which could suggest a long period
of isolation and autochthonous development. In the same paper, comparisons of similarity index analyses
show that the CDR flora has more affinity to the southern end of the Sierra Madre Oriental than it does to
the Baja/Sonoran flora. Perhaps because there do not seem to be distinctive topographic limits to northern
vegetative expansion, the limits of the CDR may be more climatically controlled (McLaughlin 1989): CDR
flora shows more ai to coastal Peru than to the Great Basin (Rzedowski 1973). Climate as a limiting
factor becomes iff t when realizing that the Great Basin, Sonoran, and Chihuahuan deserts are
linked topographically and geologically as members of the Basin ena Range province.
Individual species’ tolerances are probably what d d l changes in response to the
changing climate. However, as McLaughlin (1986) points out, dies is no reason why, on a larger scale, there
cannot be found coherent assemblages of species occurring in non-random patterns. Many floristic regions,
delineated as places where the climate acts upon the vegetation (as opposed to more local vegetational areas,
using delimiters like soils or geography), have been applied to the Southwest (Dice 1943; Cronquist 1982;
Takhtajan 1986; McLaughlin 1986; Bailey 1998). The boundaries of these large-scale, ecological regions can
be drawn strictly using climate and gross vegetational features (Bailey 1998), by using centers of endemism
to create distinct groupings (Cronquist 1982; Takhtajan 1986), which could be called a “scarceness” model,
or the focus could be on the degree of overlap between individual floras throughout a region (McLaughlin
1986, 1989). This latter model does not focus on the dominant or rare taxa; rather, it takes into account all
extant species and is a method based on “commonness.” To s end, EE (1986, 1989) work has
provided floristically-based evidence torical distinctions, intuitive or otherwise.
Interestingly, the area of soutien er and es New Mexico, where Henrickson and John-
Fenstermacher et al., Vascular flora of the Dead Horse Mountains 703
ston (2004) draw an arbitrary border of the CDR because of its perceived transitional nature, is shown by
McLaughlin (1989) to be part of a distinct floristic area originally intuitively recognized by Dice (1943).
McLaughlin's (1989) similarity indices identified an outlying connection between his so-called “Apachian”
flora and the Davis Mountains region of the Big Bend, which Turner (1959) actually suggested in his floris-
tic interpretation of the area. Also in support of this connection, the Davis Mountains, based on a subset
of its flora (Larke 1989), has a family profile more similar to that of the Southwest (McLaughlin 1989),
and is located more closely to the core of the Apachian element than to floras in the southern Big Bend.
The Apachian floristic element is thought to be autochthonous but allied to the Sierra Madre Occidental
(McLaughlin 1989). Perhaps during the expansions and contractions of vegetation communities in response
to Pleistocene climate change, this Apachian center extended its influence into the Big Bend. As many as
25 glacial-interglacial periods have affected the southwest (Henrickson & Johnston 2004), allowing more
temperate plant species to expand into the Big Bend region from both the north and the south. In the Chisos
Mountains of BBNP, cuan menziesii and EE Ee occur with the Mexican montane species
Cupressus arizonica and what is believed to be Pi (Powell 1998). In the DH, cooler-climate species
that may be remnants of glacial expansion include Achnatherum curvifolium from the north and the Mexican
pinyons from the south. la warmer times, the desert scrub and more tropical species expanded from the
south. These climate fluctuations could have allowed for speciation through isolation, but there would have
been more ities for diversification in the southern CDR, away from more extreme climate changes
coming Gas, the continental interior (Van Devender 1986). Of course, any discussion of speciation must
acknowledge that the process is not simply a function of time or climate. Life forms, breeding systems, and
genetics are also critical in producing differential speciation abilities (Grant 1958). However, perhaps more
influential than genetic isolation, extinction may have been a more effective mechanism than speciation in
affecting today's floristic diversity in the Big Bend.
More floristic study is warranted for the region. Beyond simply improving baseline knowledge of the
Trans-Pecos flora, previous floristic work (McLaughlin 1986, 1989) should be revisited and improved by
updating the original data, since the size of several Trans-Pecos floras have increased by 40-50% since
the 1980s (e.g., Warnock 1967 in McLaughlin 1986 and Worthington 2001). Regionally, similarity index
studies similar to those by McLaughlin (1986, 1989, 2007) and especially Christie (2006) could be used
to elucidate in more detail the floristic influences on the Big Bend region and might help to identify more
concretely the distincti g CDR provinces. In this context, the completion of the present Dead Horse
Mountains flora constitutes a cca step towards a more complete understanding of West Texas and
regional floristic relationships.
ANNOTATED CHECKLIST OF VASCULAR PLANT TAXA
Species are arranged by divisions following Raven et al. (2003): Lycophyta, Pteridophyta, Coniferophyta,
Gnetophyta, and Anthophyta. The flowering plants are subdivided into the classes Monocotyledones and
Eudicotyledones. Within these hierarchical groupings, taxa are listed alphabetically by family, genus, spe-
cies, and infraspecific rank as appropriate. Beyond a basic reliance on the Manual of Vascular Plants of Texas
(Correll & Johnston 1970), taxonomy and nomenclature were taken preferentially from several updated
sources, including Powell (in prep.) and Powell et al. (in ms.) for non-woody vascular species and genera,
the Flora of North America volumes for the Poaceae and Asteraceae (FNA 2003b, 2006, 2007), and Powell
and Weedin (2004) for the Cactaceae.

Symphyotrichum sericeum (Vent.) Nesom and S. pratense (Raf.) Nesom are two closely related taxa of central
and eastern United States. In most treat ts they have been maintained as distinct species (e.g., Correll &
Johnston 1970, Cronquist 1980, Jones 1990, Nesom 1994, Brouillet et al. 2006). When the taxa are considered
to be conspecific (see Wunderlin & Hansen 2004), S. pratense is treated as S. sericeum var. microphyllum (DC)
Wunderlin & B.F. Hansen. Symphyotrichum pratense was known for many years as Aster phyllolepis Torr. &
A. Gray. Symphyotrichum sericeum is generally EE in the EE states, from Texas to North Dakota
and southern Canada, to western Michigan. Sym; trated in eastern Texas

The present study provides a detailed view of the geographic distribution of Symphyotrichum sericeum
and S. pratense, based primarily on a study of herbarium specimens from BRIT-SMU, EKY, GA, LSU, MO,
NCU, NLU, TENN, TEX-LL, UNC, VDB, and VPI. Maps are augmented by records from various published
sources. The available literature on habitats, associates, and chromosome numbers was also reviewed. A
new chromosome report from a Kentucky population is based on mitotic counts from root tip squashes
from germinating achenes. The key is based on a detailed examination of morphological characteristics of
herbarium specimens from across the ranges of the two taxa.
SYMPHYOTRICHUM SERICEUM
Distribution and Habitat.—The primary distribution of Symphyotrichum sericeum is from Arkansas and
Oklahoma to southern Canada to western Michigan and Indiana, with disjunct populations in central
Texas (Fig. 1). Over the larger part of its range, S. sericeum occurs in a variety of habitats, e.g., dunes, sandy
woods, glades, sandstone glades, over granite outcrop— but typically associated with seasonally dry, open
to semi-open habitat. Symphyotrichum sericeum in Texas mostly occurs on the Edwards Plateau, where it
grows on limestone hills, commonly on open, rocky slopes and roadbanks. An early collection supposedly
made far to the east (Harris Co.: Lindheimer 78, BRIT) is similar in every respect to Edwards Plateau plants
and may be mislabeled. Swink and Wilhelm (1994) list a number of associates of this species in Illinois,
including Amorpha canescens, Schizachyrium scoparium, and Bouteloua curtipendula in dry hill prairies, and
Anemone cylindrica, Liatris aspera, Liatris cylindracea, and Spiranthes cernua in sand barrens sites near Lake
Michigan. In Wisconsin it occurs at dry prairie sites on hillsides, outcrops, and bluffs, sometimes under
oaks, jack pine, or red cedar, but usually in the open in habitats dominated by Schizachyrium scoparium, with
Asclepias viridiflora, Dalea purpurea, and Brickellia eupatorioides (Cochrane & Iltis SEL In Manitoba the
species occurs in remnant tall-grass prairie sites and in openings in Q pa/Populus tremuloides
woodlands (Foster & Hamel 2006).
The species is primarily associated with the Central Lowlands Physiographic Province in the m S. punt
it also occurs in the Ozark Plateau Province of Arl d Missouri. A recent collection
sericeum from open shale barrens on a southwest-facing slope in central Arkansas, is pandy the first
record from the Ouachita Mountains Province. This site is disjunct from the nearest populations about 155
km to the northeast on the Ozark Plateau. Voucher: Garland Co.: Ouachita Mountains, Ouachita National
Forest, steep S-facing shale barrens (Mazarn Formation) on upper slope, east of and above Walnut Creek
near point at which it flows into Lake Ouachita, Crystal Springs 7.5” quadrangle, steep glades, elev. 750
ft, hundreds of plants in high quality shale barrens, 29 Sep 2006, Witsell 06-471 (ANHC,BRIT, UARK). A
second population was subsequently found in similar habitat 1.9 km northwest of the above site
Chromosome Numbers.—There are about a dozen published diploid counts for Symphyotrichum seri-
ceum, these mostly from the northern portions of its range (Jones 1980; Semple & Brouillet 1980; Semple &
Chmielewski 1987; Semple et al. 1989; poms etal. 20921, with the most Se count from Izard Co., Ar-
kansas (Sherif et al. 1983). There is apy only le report of count (Love 1982) for S. seri-
ceum, this count from Canada; t | diploid counts from this same cay (J. Semple, pers. comm.).
Taxonomy.—Brouillet et al. (2006) treated Symphyotrichum lucayanum (Britt.) Nesom as a synonym of
S. sericeum, but S. lucayanum is here id to be more closely related to S. concolor (L.) Nesom, based on
their similarities in capitulescence and phyllary morphology and their closer geographical proximity. The
latter is widespread in the southeastern U.S.A. Symphyotrichum lucayanum was treated by Nesom (1994) as a
distinct species, based on its very loosely racemiform capitulescence with interspersed leaves only slightly
reduced or not at all from the proximal cauline, different from the more densely congested, bracteate capit-
ulescence of S. concolor. Turner (1982) treated the taxon as a synonym of Aster concolor L., and the type of
Aster lucayanum Britt. See E EE 2448, NY!) was annotated be W.T. Gillis in 1974 as A. concolor.
State-Rarity. | sericeum is currently ranked as S2 (Threatened or Rare) in Arkansas,
Indiana, Michigan, See North Dakota (NatureServe 2008). It is listed as Nationally Threatened in Canada

(Foster & Hamel 2006). We could find no substantiation of the occurrence of S. sericeum in Georgia, Ohio,
or Tennessee, where indicated to occur by Brouillet et al. (2006) and NatureServe (2008).
SYMPHYOTRICHUM PRATENSE
Distribution and Habitat.—The densest distribution of 9 phyotrichum pratense isi ce E and
southern iind ace disjunct Ge of populati l over
and in a variety of physi E. 2). 5 wish pratense in Texas charsetetistisálly occurs
in sandy soil m) € lesa Bands ge silty clay, silty clay-loam), being largely restricted to the follow-
ing natural regions: Piney Woods, Oak Woods and Prairie, Gulf Coast Prairie and Marshes, and Blackland
Prairie. Within these regions, it is less frequent in blackland prairie: e.g., Texas. Dallas Co.: Lundell 12032
(LL, SMU). Shinners (1950), who recognized the legitimacy of the Rafinesque name ahead of the Torrey &
Gray name, described this species as "a frequent and showy plant of open oak woods and transition-belt
prairies thoughout east Texas ..." In Texas, S. pratense also occurs in longleaf and loblolly pine areas and in
coastal prae EE and it as Reco a GER fields, roadsides, clearings, and fencerows.
In 1 d sites , blackland prairie, chalk hills, and cal la
as well as along dry EE A blaciland prairie locality for Symphyotrichum pratense is on the “Kieffer
Prairie:” Winn Par.: Brown 8220 (SMU) and five other collections from the same locality (LSU Herbarium
Online Database 2008). At the nid Prairie E Ene grows with associates such as Schizachyrium sco-
parium, Andropogon gerardii, Sorgl , Echi pallida, Oligoneuron rigidum, and Vernonia missurica
(USDA MA Sopas 2008).
In the Gulf Coastal Plain of me typical habitat for Symphyotrichum pratense is open saline
barrens—treeless openings in Pinus taed imilis flatwoods with clay soils containing high levels of
sodium and/or magnesium. Eric Sundell, viis first discovered the species in Arkansas at the Warren Prairie
(Sundell 1983), noted that the pane occurred with prickly pear and ER palmetto and that a number of
other rare species were jated with these sites, including G and Schoenolirion wrightii.
The USDA Plants website (USDA, NRCS 2008) lists Izard and Neon counties in Arkansas for S. pratense,
but these records from northern Arkansas are based on collections of S. sericeum.
Eastward (to Alabama, Florida, Georgia, Kentucky, Mississippi, Tennessee, and Virginia), Symphyotrichum
pratense occurs mostly in calcareous habitats, e.g., chalk barrens, cedar glades, and limestone outcrops. Kral
(1981) reported on the species at Coastal Plain sites in Alabama (Sumter Co.) and Florida (Gadsden Co.) and
noted that the plants in Alabama were found in blackland prairie patches and that those in Florida were
found at rocky calcareous outcrops in association with Schoenus nigricans, a plant more normally found near
the coast. The species subsequently was discovered in Decatur Co., Georgia, just across the state line from
Gadsden Co., in calcareous glades on a bluff: Decatur Co.: Godfrey & Gholson 80099 (GA). In Mississippi
the species occurs in association SR Ge chalky outcrops (L. McCook, pers. comm.). The central
Alabama and Mississippi popul ted in the Black Belt prairie lands (see Barone 2005). The most
northerly populations in Alabama occur in o prairie Caen within the Highland Rim province,
along with many other rare species, including Dalea gattingeri, Leavenworthia alabamica, Cypripedium can-
didum, Eriogonum longifolium var. harperi, Schoenolirion croceum, and Spiranthes magnicamporum (Webb et al.
1997).
At its most northerly range limits in Kentucky, Symphyotrichum pratense is found in glades or barrens
habitats of the Interior Low Plateaus (chiefly Highland Rim sites) with Juniperus virginiana and Quercus
marilandica as the woody dominants and with Andropogon gerardii, Schizachyrium scoparium, Sorghastrum
nutans, Sporobolus compositus, and S. vaginiflorus as the conspicuous grasses. These habitats often contain
a variety of other rare or infrequent plants, such as Cypripedium candidum, Echinacea pallida, Liatris aspera,
Liatris cylindracea, Lithospermum canescens, Silphium pinnatifidum, Dalea candida, Dalea purpurea, and Phys-
ostegia virginiana (Cranfill 1991; Kentucky State Nature Preserves Commission 2008). The barrens sites in

are very similar to the Kentucky sites and also contain a number of very rare species (DeSelm 1990; Ludwig
1999; Tennessee Natural Heritage Program 2008). In northern Georgia the plants occur at both Appalachian
Plateau and at Valley and Ridge sites (T. Patrick, pers. comm.). In the Coosa river watershed of Georgia,
S. pratense occurs in limestone glades; other species associated with this habitat include Asclepias hirtella,
Baptisia australis, Buchnera americana, Dalea gattingeri, Echinacea pallida, Hypericum dolabriforme, Hypericum

Recent investigations of dolomite and limestone barrens in southwestern Virginia have discovered
several populations of Symphyotrichum pratense -- initially reported by Ludwig (1999), subsequently treated
by Brouillet et al. (2006), Weakley (2007), and Virginia Botanical Associates (2008). We have studied the
following vouchers: Russell Co.: 1 km E of Carterton, one-acre barren at top of SW-facing slope on W end
of a short ridge, dense grass cover with dolomitic limestone cobbles, 20 May 1996 [not yet in flower], Wie-
boldt 9415 (VPI); river knob 1 km E of Carterton, top of SW-facing hardwood slope, substrate cobbly with
dolomitic (?) limestone, 2100 ft, dominant species with Liatris aspera and Andropogon gerardii, scattered over
most of one-acre barren, 17 Sep 1996, Wieboldt 9605 (VDB, VPI); E side of Mill Creek where it cuts through
ridge between Clinch River and Reeds Valley, ca. 1.9 km N of Jessees Mill, SW-facing limestone hillside in
open grassland dominated by Schizachyrium scoparium, 2040 ft, ca. 20 plants, 11 Sep 1996, Ludwig 3082
(VPI). Wise Co.: Fleming 14122 (GMUF). Ludwig (1999) noted that this species has | found at six Russell

Chromosome Numbers.—The first report of the tetraploid level of 2n=20 for Symphyotrichum pratense
was from Gonzales Co., Texas, by Semple and Brouillet (1980), who noted that a diploid count had been
made earlier for the species, but that report was unvouchered and part of a 1945 embryological study by
German anatomists. Semple and Chmielewski (1987) published diploid counts for plants from Grimes and
Walker counties in Texas and a tetraploid count for plants in Milam Co., Texas. Two years later Semple et.
al. (1989), reported a diploid count of 2n=10 for plants from Gadsden Co., Florida. In addition, we report
a previously unpublished 2n=20 count for S. pratense: Kentucky. Hardin Co.: cedar glade off KY 2762, 6
Nov 1987, R.L. Jones 5457 (EKY).
Taxonomy.—in the main part of the range of Symphyotrichum pratense, the plants typically have phyl-
lary surfaces mostly AMAA ang ge Ge with the spreading-ciliate margins. Phyllaries of the
Virginia plants are faces, with or without strongly ciliate margins, but
resemble typical S. marae of ee and Lona: in the proximal indurate portion of the phyllary being
relatively short, the distal leafy portion being relatively broad and long, and the overall phyllary length about
1.5 cm. Their geographic position also obviously suggests that they are part of S. pratense. Some plants from
Tennessee are similar in their phyllary features (e.g., Roane Co.: Morton 1307, SMU)
The description of Aster montanus Nutt. seems to refer to Symphyotrichum pratense; Nuttall noted that it
was “nearly allied to the preceding [Aster sericeus], but distinct." Torrey and Gray (in Fl. N. Amer.) treated
it as A. sericeus var. p. They also noted that the species was known from "Tennessee and North Carolina
near the mountains." On Nuttall's 1816 trip, he crossed from Tennessee to Asheville, N.C., and went on
to Rutherfordton and Morganton (Graustein 1967). Gray (in Synop. Fl. N. Amer. ) formalized the name at
varietal rank, as Aster sericeus var. montanus (Nutt.) Gray, noting that the involucre is “sometimes glabrate
and villose-ciliate; approaching the next species [A. phyllolepis].” An image of the holotype of A. montanus
was obtained from PH, and an examination indicates that the involucral widths are about 2 cm wide, much
larger than typical S. sericeum, and we therefore place this name in the synonomy of S. pratense.
Today neither S. sericeum nor S. pratense is known to occur in North Carolina. Gray (in Fl. N. Amer.)
listed North Carolina as included in the range of A. sericeus var. B, and later (in Synop. Fl. N. Amer), he
specified Buncombe County as the site of the collection. The specimen upon which Gray apparently based
his comment was located at NY, and an image was obtained. The sheet bears three plants from two dif-
ferent areas—two are from Minnesota and identified as Aster sericeus, while the other was collected from
“Buncombe, North Carolina, Gibbes” and identified as “A. sericeus B. (montanus Nutt.).” This latter specimen
exhibits the large heads of S. pratense, and is here assigned to that taxon; it represents the only known record
of the species from North Carolina. S. pratense has not been subsequently rediscovered in the state and can
be assumed to be extirpated there.

When these disj lati f Symphyotricl i were first discovered in eastern U.S., especially
at the more northerly bes in Albane. eessen and Kentucky, they were often identified as S. sericeum.
They are still listed as such in several state natural heritage databases. We now confirm all examined speci-
mens from Alabama, Florida, Georgia, Kentucky, Mississippi, North Carolina, Tennessee, and Virginia as
S. pratense.

CONCLUSION
Symphyotrichum pratense and S. sericeum are distinct species of central and eastern U.S. They are largely al-
lopatric in distribution, and occur sympatrically only in Texas, where S. pratense is common and S. sericeum
rare. Symphyotrichum pratense is associated with a range of physiographic provinces—it is chiefly Coastal
Plain in distribution, but its range extends to the Interior Low Plateaus, the Appalachian Plateau, and the
Valley and Ridge. There is an historical record from the Blue Ridge of North Carolina. Symphyotrichum seri-
ceum is largely associated with the Central Lowlands Province and the Ozark Plateau, and only sporadically
into adjacent provinces to the south, north, and west. Disjunct populations and population systems are a
prominent feature of the biology of both taxa. There is some EE in phyllary pubescence in the
easternmost disjunct populations, but tl f lting from local genetic drift
in populations far removed from the main range of the species, and there is no ev ideme of any significant
gene interchange between the taxa. The available evidence indicates that S. sericeum consists of diploid
populations (with the exception of one lous report) and that S. pratense contains populations at both
ploidy levels. Symphyotrichum sericeum is generally common throughout much of its a considered rare
only in the states at the eastern and southern periphery of its range (Michigan, Indiana, and Arkansas), and
is Nationally Threatened in Canada. Outside of Texas and Louisiana, S. pratense is a rare plant and is con-
sidered critically imperiled in several states (Alabama, ee amd Tennessee, and Virginia). The
identity of these disjunct eastern populations has been the soi ome confusion in the past — they have
been variously treated by the duret states as 5. pratense or S. sericeum, and this latter name continues to
be used by some eastern states for their rare species lists. Our study concludes that all specimens examined
from populations in Alabama, Florida, Georgia, Kentucky, Mississippi, North Carolina, Tennessee, and
Virginia, are S. pratense.

A population of Ranunculus ficaria L. (lesser celandine, fig buttercup) was discovered in flower immediately
adjacent to Overton Creek in Fort Worth's Overton Park, near the center of the city. The creek at this point
runs through a broad but relatively steep-sided ravine and is about three miles above confluence with the
Trinity River. Tributaries of Overton Creek pass through several miles of urban neighborhood upstream
from this area. The creek commonly rises beyond its banks in heavy rain.
Thirty discrete plants, clearly Ruan. ey in an area of about 30 square feet—the largest produced
lants occurs on the stream terrace about 300 yards
at least 20 flowers. A second p
downstream.

in North America, the plants occur on shaded stream banks, floodplains, low woods, and moist disturbed
areas. “Flowering usually occurs from late winter through mid-spring (March through May), depending
on conditions. Afterwards, the above-ground portions die back" (Swearingen 2005). Ranunculus ficaria is a
beautiful horticultural species, and many photos are available on the internet.

of the grains are non-staining and distinctly smaller (and highly variable in size). All achenes apparently
are glabrous and infertile. Axillary bulbils were not present at the time of collection (8 March) but were in
abundant production by 2 April—they are whitish, conic-cylindric to short-cylindric, and essentially without
surface features. Superficially, at least, the axillary bulbils are very similar to the root tubers. Many stems
and leaves had at least begun to wither by 5 May, with the axillary bulbils loosened and easily detached.
Cn in Renan Caen of bovis ME taxa is further tempered by Whittemore's observations
(1997): * ( ially in leaf size and stem posture), and many att ts have
been made to dide it into varieties or sbspeciés Ges Sell 1994). The different forms, however, intergrade
extensively and the varieties are often impossible to distinguish." Sell himself noted (p. 47) that *a large
proportion of herbarium specimens cannot be determined with certainty" and relied on field experience in
the British Isles and on published literature to summarize distributions of the infraspecific taxa.
Sell (1994) noted that “all the subspecies can spread by tubers (Clones of all the subspecies can be
produced by division of the root tubers.), two spread by axillary bulbils, and all except subsp. [bulbifera] can
spread by seed." Both the tubers and bulbils are easily carried downstream during flood events (Bargeron
et al. 2003). Bulbils are produced near the end of flowering or in fruit maturation, and Sell noted that the
five taxa can be recognized “if cultivated, or if examined at intervals through their flowering and fruit-
ing periods." Detailed observations of this nature, however, apparently have not been recorded in North
America—Magee and Ahles (1999) and Rhoads and Block (2007) unequivocally specify that the plants
produce bulbils, but other U.S.A. floras note that bulbils are produced "sometimes" or "often." Only Magee

ized in Oregon, Washington, and British Columbia and from Missouri, Tennessee, and Virginia northward
to Ontario, Quebec, and Newfoundland (PLANTS Database 2008). The Texas plants are the southernmost
known for the species as naturalized in the U.S.A. It is reported to be invasive in Connecticut, Delaware,
Maryland, New Jersey, Oregon, Pennsylvania, Virginia, Wisconsin, West Virginia, and the District of Co-
lumbia (Plant Conservation Alliance 2007).

INTRODUCTION
Plant invasions are a major issue for ecosystems around the world (Williamson 1996; Gurevitch & Padilla
2004). The EEN e SES ey Eyer urbanization, intensive agriculture and horticultural
practices, i of natural habitats, biog hical factors, and climate
change are some olt the driving forces hari increase the movement of species around the world (Mooney &
Hobbs 2000; Vila & Pujadas 2001; Myers & Bazely 2003; Py3ek € Richardson 2006). As a result, the flora
in many regions of the United States, including California, is now rich in nonnative (alien, exotic) plants
(Westbrooks 1998; Bossard & Randall 2007).
Invasive plant species reproduce in very large numbers, are superior competitors, and have the poten-
tial to spread across large areas and at considerable distances from parent plants (Richardson et al. 2000).
Environmental plant pests (species that affect the loss of native biodiversity) and ecosystem transformers

(species that alter the character, condition, form, or function of ecosystems) pose a serious threat to wild-
lands in California and elsewhere (Randall 1997; Vitousek et al. 1997; Richardson et al. 2000; Bossard &
Randall 2007). In California's estuarine wetlands, some of the most problematic and well-known ecosystem
transformers are the introduced Spartina species, especially S. alterniflora Loisel. and its hybrids (Callaway
2005; California Conservancy 2007).
Historically, the coastal plains of California have been 11 ltiple introductions for long periods

1999: Cronk & Fennessy 2001; Zedler & Kercher 2004). In southern California, expanding urbanization
provides year-round sources of water from runoff and discharge of wastewaters into natural drainages,
which provide direct pathways of dispersal for nonnative species spreading from uplands to wetlands at the
wildland-urban interface (White & Greer 2006; Riefner & Boyd 2007).

PREVIOUS KNOWLEDGE
Distribution. eim vaginatum is a perennial grass documented from warm, coastal regions around
the world, incl t and southeast Europe, tropical Africa, temperate and tropical Ásia (Arabia,
China, India, Malaysia), Australia, New Zealand, French Polynesia, the Galápagos Islands, Hawaii, and other
Pacific Islands. the Caribbean, Central and South America, and the Atlantic and Gulf Coasts of the United
States and Mexico in North America (Waterl 1997; Allen & Hall 2003; Zuloaga et al. 2003; Clayton
et al. 2006). Its exact native range, which is centered in the tropical and subtropical regions of the New
World, remains uncertain (Chase 1929; Wagner et al. 1999; Edgar & Connor 2000; Weber 2003). In the
United States, P. vaginatum occurs from North Carolina to Florida, west in the Gulf States to Texas, and in
New Mexico, but was not previously reported for California (Webster 1993; Allen & Hall 2003; DiTomaso
& SECH 200r, USDA id cam Flora Project 2008).

nor 2000: Filigheddu et al. 2001; Allen & Hall 2003; Shaw & Allen 2003; Dana et al. 2004; Siemens 2006).
Anthropogenic Uses and Worldwide Introductions.—Paspalum vaginatum has numerous anthro-
pogenic uses that have transported it to many countries around the world, and eventually to southern
California. Historically, it was used as bedding in trade ships that sailed between Africa, North and South
America, Central America, and the Caribbean Islands during the 1700s and 1800s (Duncan & Carrow 1999).
Paspalum vaginatum has also been used widely for rehabilitation of salt-affected lands, stabilization of sand
dunes and dredge materials, restoration of coastal wetlands, and forage for livestock (Leithead et al. 1971;
OIC 1990; Vargas 1995; NRCS 1999; Loch & Lees 2001; Barrett-Lennard et al. 2003; Fontenot 2007).
As water shortages continue to escalate worldwide, increased use of saline water or poor-quality re-
claimed effluent waters for turf landscape irrigation is necessary (Snow 2001). The systematic development
and cultivation of varieties (cultivars) of turf grasses with improved tolerance to saline soils and low-quality
irrigation waters, including P. vaginatum, are playing a central role in the turf grass industry (Henry 1981;
Hall 1994; Brown et al. 1998; Carrow & Duncan 1998; Duncan 2003; Marcum 2004). To meet the demands
of water conservation and expanding recreational needs, P. vaginatum is now grown on golf courses in Ásia
(including Malaysia, Indonesia, and the Philippines), South Africa, the Middle East, Sardinia, New Zealand,
South America, Hawaii, the Caribbean Islands, and across the southern United States (Duncan & Carrow
1999; Beard 2002). Paspalum vaginatum is also used as a ground cover in gardens, and new cultivars are

highly promoted for lawns in the southern United States (USDA Zones 7-10), Australia, Hawaii, and else-
where (Duncan & Carrow 1999; Rushing 2006; Christians et al. 2007; Tukey 2007).
Environmental Tolerances Create a Competitive Advantage.—Paspalum vaginatum has broad
ecological tolerances and life history traits that aid its widespread establishment and utility to land and
resource managers worldwide. It is an EE aggressive, SC and stoloniferous mat-forming
perennial grass that often f ies (Hitchcock 1951; Weber 2003). It roots well in sand, clay,
silt or mucky soils in acidi Ikaline conditions, is tolerant ih waterlogged and highly saline soils, prospers
in low fertility soils and poor-quality effluent waters used for irrigation, is highly tolerant of mechanical
Done and heavy livestock grazing, has high shoot density for effective soil ao develops a thick
f tolerant of foot traffic and wear, and is not readily tible to drought or pathogens
ica 1999; Duncan & Carrow 1999; Loch & Lees 2001; BxirettLeunard e et al. 2003; Lee et al. 2004a,b;
Fontenot 2007). Therefore, its rapid growth, abundant propagules (in this case rhizome and stolon frag-
ments), and broad environmental tolerances are important characteristics typical of an “ideal weed" (Sakai
et al. 2001). In a given environment, these characteristics often confer an advantage to a nonnative species
relative to indigenous species (Barney & DiTomaso 2008).
Invasive Status Worldwide.—Paspalum vaginatum is well known for its aggressive behavior and its
ability to dee nes ecosystem renun (Weber 2003). It is an bean) and eee STEE of disturbed,

years Shaw & Allen 2003). "eiim XE DONUM is, however, selfincompatible rarely produces viable seed
t quantity, and therefore, must | ted vegetatively (I Iall 1994- Duncan & Carrow 1999).
Hone it would be careless to conclude that Se lacking sexual reproduction cannot become serious
invaders; giant reed (Arundo donax L.) is a classic example of a sterile but highly invasive plant of southern
California's riparian habitats (Bossard et al. 2000; Barney & DiTomaso 2008).
Outside of cultivation, vegetative reproduction of P. vaginatum would be possible through animal graz-
ing and other natural physical regimes that would disturb and transport rhizomes and stolons (Graeme
& Kendal 2001). Paspalum vaginatum is apparently dispersed primarily by water when pieces of stolon or
rhizome are carried often long distances by streams. ZE ye fragments root easily, forming new
plants that start new infestations (Weber 2003). Est ts, shallow brackish lagoons or tidal creeks,
and gaps in disturbed wetlands or scoured streambeds that are not adi colonized by indigenous species
are highly vulnerable to invasion (Filigheddu et al. 2001; Shaw & Allen 2003; Siemens 2006). Importantly,
P. vaginatum and its impacts on the function of native estuarine ecosystems are significant and comparable
to the well-documented invasions by nonnative Spartina species (Graeme & genii 2001; Allen & Shaw
2003; Dana et al. 2004; Siemens 2006).
In New Zealand estuaries, and much like the ecological impacts effected by introduced Spartina spe-
cies, P. vaginatum transforms the composition and structure of indigenous vegetation by growing over and
displacing low-stature species, endangering populations of threatened species, altering fish spawning and
feeding grounds, prohibiting burrowing fauna and reducing access to feeding sites and roosting by shore
birds due to its high shoot and root density, and altering estuarine hydrology by accumulating sediments
(Graeme & Kendal 2001; Shaw & Allen 2003).
Similar negative effects in brackish wetlands have been documented in Spain, where P. vaginatum dis-
places halophytes and alters the composition and structure of native communities, promotes accumulation
of sediments and organic detritus, and alters hydrological and nutrient regimes (Dana et al. 2004). Accord-
ingly, P. vaginatum has been classified as *dangerous" (a species causing ecological damage or alteration to
natural ecosystems) (Dana et al. 2007). Paspalum vaginatum has also been classified as invasive in Portugal
(Domingues de Almeida & Freitas 2006).
In the Galapagos Islands, EEN P. agi atum stands out as a special case. It has aggressively invaded
disturbed and natural wetlands where ive plants, and affects wai t and soil moisture
content (Vargas 1995; Gravez et al. 2004; Guézou et al. 2007). Paspalum vaginatum has also successfully

invaded many lagoons, threatening these ecosystems and their globally significant avifaunal biodiversity.
Quantitative investigations have GE that P. Laid eus are EE for E

lagoons (Siemens 2006). Accordingly, its control and eradication are necessary in order to maintain the
status of the Galápagos Islands lagoons as a Ramsar Internationally Important Wetland (Siemens 2006).
In South Africa, Héfliger & Scholz (1980) documented similar negative affects to native community
functions, including competition for space, light, water, and nutrients, replacement of native vegetation,
en of water flow, iu contaminant seed loading. Further, the invasion of P. vaginatum and other
nonna 1 the sand and mudflats of the Wilderness Lakes Wetland (designated a Ramsar
site) unstable for wading birds (Randall & Russell 1995).
Paspalum vaginatum is also invasive and has been classified as a "significant environmental weed" in
Australia (Randall 2007). It is also invasive in the Hawaiian Islands and the Marshall Islands (Wagner et al.
1999; Whistler & Steele 1999; Vander Velde 2003). Accordingly, PIER (2007) has ranked P. vaginatum as a
"high risk" invasive species.

SIGNIFICANCE IN SOUTHERN CALIFORNIA
Introduction, Dispersal, and Naturalization.—These naturalized populations represent the first docu-
mented records of P. vaginatum for California (Webster 1993; Allen & Hall 2003; USDA 2007). Paspalum
vaginatum has also not been included in major publications on nonnative species established in California
(Bossard et al. 2000; Hrusa et al. 2002; DiTomaso & Healy 2003; Bossard & Randall 2007; DiTomaso & Healy
2007; Grewell et al. 2007). Thus far, P. vaginatum has not been of concern in southern California (Roberts
1998; Roberts et al. 2004; Rebman & Simpson 2006; Clarke et al. 2007; Riefner & Boyd 2007)
Biologists often have difficulty tracing the source of nonnative organisms and verifying their acciden-
tal versus intentional human transport across natural boundaries. However, the arrival of P. vaginatum in
California is most likely the result of purposeful introductions, presumably for soil stabilization and habitat
enhancement projects or more likely for cultivation of turf grass for lawns, parks, and golt courses. Native in
the southeastern United States, P. vaginatum has been used for restoration of coastal wetlands, stabilization
of dunes, banks, and dredge materials in the Gulf States (Duncan & Carrow 1999; NRCS 1999; Fontenot
2007). Accordingly, it may have been introduced for enhancement or restoration of salt marsh habitats in
southern California, but we have not been able to confirm this.
However, P. vaginatum was introduced to southern California for cultivation as a turf grass during the
1970s and 1980s for research at the University of California South Coast Field Station in El Toro, Orange
County, and for commercial production in Indio, Riverside County. It was also planted for turf grass in
Laguna Niguel, Orange County, and at Rancho Santa Fe, San Diego County (Henry et al. 1979; Duncan &
Carrow 1999). As documented by herbarium records (Sanders et al. 15885, RSA; originally identified as P.
distichum), the earliest escaped and naturalized plants were collected in 1994 near the Salton Sea, Riverside
County (Fig. 1). The senior author also made observations of P. vaginatum in 1994 (originally identified as
P. distichum and not collected) at Doheny State Beach, City of Dana Point, Orange County, during surveys
conducted for California State Parks (Fig. 1). Species beginning to escape cultivation receive little attention,
largely because of the difficulty in identifying and locating them before they become established in native
communities. Time lags in plant invasions, a phase when plants are difficult to document during early dis-
persal, then exponential growth, naturalization in native communities, and subsequent spread describes
a typical invasion scenario (Sakai et al. 2001; Schierenbeck et al. 2007). In the case of P. vaginatum, plants
escaping cultivation from sites in El Toro and Laguna Niguel, Orange County, to native habitats on the coast
at Dana Point, Orange County, and from inland sites at Indio to near the Salton Sea in Riverside County,
perhaps during the 1990s, appears to be a logical scenario for southern California (Fig. 1).
nH TË a | L ,P | a A H al CRUE a 749
For this reason, we believe turf plantings may be the most likely source of propagules that dispersed
from irrigated urban landscapes downstream to native plant wetland communities. Although its reproduc-
tion outside of cultivation and dispersal mechanisms are not well understood, P. vaginatum may have been
spread vegetatively by animals, carried by mechanized landscape equipment to new sites, or rhizome and
stolon fragments may have been dispersed by water during storm events from turf plantings in the uplands
into urban drainages and then downstream to native wetland communities.
Paspalum vaginatum is now widely naturalized in southern California's coastal wetlands and at inland
habitats near the Salton Sea (Fig. 1). Itis most common in estuarine wetlands where it can form monocultures
on mudflats, tidal marshes, and shores of estuary lagoons (Fig. 2), or along tidal creeks and sloughs (Fig.
3). Bare soils of tidal mudflats (Fig. 4) and wet sand of disturbed streambeds (Fig. 5) appear to be highly
vulnerable to colonization. Paspalum vaginatum also grows in many non-saline wetland habitats, including
disturbed riparian scrub and slow-moving waters of urban creeks in coastal and desert regions. However,
P. vaginatum is unlikely to form extensive monocultures or survive long-term competition from large, fast-
growing plants and shrubs Bus pi a environments.
Urbanization a Wetl Paspalum vaginatum is one of many subtropical and tropical non-
hed and ding in southern California. Expanding urbanization has fragmented
natu habitats, encouraging nonnative planis cultivated in cities to move easily from human-maintained
landscapes to native communities (Vitousek et al. 1996; Cronk & Fennessy 2001). In urban environments,
wetlands often accumulate debris and sediments, and receive floodwaters that supply resources (nutrient
enrichment, elevated levels of light following flood scour) that may accelerate the growth of opportunistic
nonnative plants and facilitate invasion of sunny paps in ES cann (Davis et al. 2000; nd & os
2004). In addition, hydrological and hyd ons, accelerated erosion, and
genic disturbances to wetland and "s habitats have created numerous —á for invasion by
nonnative hydrophytes (Newman et al. 1996; Tickner at al. 2001; Werner & Zedler 2002).
Historically, summer drought and the seasonal nature of stream flows in coastal southern California
have acted as a barrier to colonization by nonnative facultative wetland plants in the wildland-urban inter-
face (Brigham 2007; Riefner & Boyd 2007). Increased moisture availability in urban environments, anda
oa a ephemeral to perennial stream flows owing to waste water E into a M e inan
er-dry climate] ilitated the dispersal of tl I g
California (Greer & re 2003; NE S Boyd 2007).
Biological Traits P in Estuarine Wetlands.—Many wetland plant invasions
can be explained by the ecological requirements and attributes of the potentially invasive plant species
and the local environmental opportunities afforded by anthropogenic disturbances (flooding, nutrients,
propagules, sediments) that may promote invasion and the formation of monocultures in wetland sinks
(Werner € Zedler 2002; Kercher & Zedler 2004; Zedler & Kercher 2004). In addition, the selection and
breeding for horticultural or agronomic purposes of an individual species, its a in eine naive
em mxTosT os
mrt with Acirimantal
environments, followed by escape and naturalization, often
describes a scenario typical of many invasive plants introduced and now established in the United States
(Reichard & White 2001).
Paspalum vaginatum cultivars with improved salt-tolerant characteristics have been developed and are
now used widely in the turf grass industry (Lee et al. 2004a,b; Duncan & Carrow 1999, Duncan 2003).
Paspalum vaginatum is one of the most saline-tolerant turf species available, with ecotypes exhibiting high-
vigor root and shoot growth at high salinity levels (Carrow & Duncan 1998; Beard 2002; Lee et al. 2005).
Additionally, cultivars have also been developed and evaluated for improved growth rate and transplant
survival for restoration and soil stabilization of brackish shorelines, dunes, mudflats, and dredge materials
in the Gulf Coast region of the southern United States (Duncan & Carrow 1999; NRCS 1999; Fontenot
2007).

SS to the Environment.—Our field observations indicate P. vaginatum is a threat to the ecological
function of estuarine wetlands in southern California. We currently lack experimental data to substanti-

evidence and quantitative data gathered in other countries provide sufficient baseline information indicat-
Ing its impacts to native ecosystems may be significant and comparable to the well-documented invasions

DISCUSSION
Wetlands are uniquely important one resources EE are highly vulnerable and threatened in southern
California (Ferren & Fiedler 1993). P , rapidly expanding urbanization, habitat
fragmentation, and poorly coordinated conservation programs have resulted in the long-term, unmitigated
loss and degradation of wetland resources, which are proportionally higher in California than in other parts
of the United SEN (Dahl 1990; E et al. a) To compound historic losses, wetland invasions by
threatei l ecosystem function, which may soon surpass habitat
loss as diem main cause of E on (Chapin et al. 2000; Grewell et al. 2007).

southern California, it is unlikely that the species will decline. In fact, P. vaginatum will most likely: spread
to new DEE which points to an immediate need to control or eradicate expanding infestations.
tand research programs have been developed to monitor and restore P. vaginatum-affected
wetlands in € countries (Gree & Kendal 2001). Potential strategies and resource management topics
relevant for urbanized southern California are:
1) Create awareness and educate biologists, field researchers, and resource agencies regarding the invasive
behavior of P vaginatum,
[| £ n a Inm LI PEE cd ET 4
754 Jo tl t lexas 2(1)
2) Add P vaginatum to the California Invasive Plant Council list of plants of greatest ecological concern (severe
ecological impacts on physical processes, plant and animal communities, and vegetation structure);
3) Expand field surveys to determine the complete distribution and abundance in native habitats, quantify
expanding use in urban landscapes, and determine if it is used in restorations;
4) Assign P vaginatum an obligate wetland indicator status (OBL, found >99% of the time in wetlands)
for California (Region 0) on the National List of Plant Species that Occur in Wetlands to aid wetland
delineations;
5) Identify and monitor adverse ecological changes to wetland ecosystems and potential impacts to sensitive
floral and faunal elements;
6) Develop habitat- and region-specific control programs;
7) Conduct ecological risk assessments of potential control techniques to avoid secondary impacts to sensi-
tive resources.
Perroi | naturalization of P. vaginatum d tes t gent need to implement detailed
floristic monitoring of wetland outhern California's rapidly url g ities. Early
detection of new invasive plants would likely minimize their impacts on biodiversity and ecosystem func-
tions, and reduce the high cost of control and eradication. Declines in biodiversity of wetland ecosystems
in urbanized environments are becoming a major concern to resource managers, especially in California,
which has the highest number of wildland-urban interface housing units (and associated parks, lawns,
recreational landscapes planted with turf grass) in the United States (McKinney 2002; Radeloff et al. 2005;
Schwartz et al. 2006). Accordingly, the widespread utility of P. vaginatum for turf landscapes, and potential
use in wetland restorations, may require the participation of agronomists, biologists, conservation groups,
and local and federal government ce ies where wetland biodiversity and conservation objectives
a
potentially conflict with urban landscape management practices in southern California.
