[i. p. 1.] CLEMATIS.

Kunze (‘‘ Monographie der Gattung Clematis,” in Verhandl. Bot. Vereins Brandenb.

Xxvi. pp. 83-202) reduces the forms included in our enumeration to four species, and

this is perhaps the best way of dealing with them. Thus C dioica, Linn., includes

C. acapulcensis, Hook. et Arn., C. americana, Mill. C. caripensis, H. B. K., C. caraca-

sana, DC., C. drummondiit, Torr. et Gray, C. flammulastrum, Griseb., C. grahami,

Benth., C. grossa, Benth., C. moginiana, Don., C. nervata, Benth., C. polycephala, Bert.,

C. pubescens, Benth., and C. sericea, H. B. K.; C. paucifiora, Nutt., is reduced to

C. lasiantha, Nutt., a common Californian species; C. filifera, Benth., and C. pitcheri,

Torr. & Gr., are referred to C. simsi, Sweet (C. cordata, Sims, Bot. Mag. t. 1816), a

species ranging from Mississippi State to Mexico; finally, C. reticulata, Walt., is

reduced to C. viorna, Linn., which, as circumscribed by Kunze, has a wide range in

Eastern North America, and also occurs in Amur-land.

Watson regards C. filifera, Benth., as a synonym of this.

+ This does not profess to be complete, but is intended to include as nearly as possible all the new facts

bearing upon the distribution of the plants of Mexico and Central America. There is a very considerable

number of new species from North Mexico, as well as an extension of the range into Mexico of many addi-

tional Texan and New Mexican species.

fi. p. 3.] THALICTRUM.

A Monograph of this genus by J. C. Lecoyer has lately appeared (Bull. Soc. Bot. Belg.

xxiv. 1885, pp. 78-824, tt. 1-5), and the author describes three proposed new species

from within our limits. Altogether he admits sixty-nine species, which he classifies in

two ranks according to their degree of distinctness, designating them primary and

secondary species. Out of the sixty-nine species retained by Lecoyer, thirty-three are

peculiar to Asia, five to Europe, one to Africa, and twenty to America. The Mexican

and Central-American species enumerated in this Monograph follow, the primary

species being preceded by a star :—

*T. hernandezi, Tausch., 7. lanatum, Lec., n. sp. (South Mexico), T. peltatum, DC..

(Costa Rica), *7'. pubdigerum, Benth., *7. longistylum, DC., *2. galeotti, Lec., n. sp.

(South Mexico), 7. gibbosum, Lec., n. sp. (South Mexico), *Z. wrightii, A. Gr.,

T. fendleri, Engelm.

Including his new species, Lecoyer records only nine, against our eleven, species.

On the evidence of collectors’ numbers alone, he declares (loc. cit. p. 319) our 7. séri-

gillosum to be a mixture of T. pubigerum and T. hernandezii. The former is a very

distinct species, of which we have examined the type specimen; and as to the latter, of

which we have seen no authenticated specimens, if correctly described, it is quite

different from ours. |

instances, we have not had the same species as he; numbered collections have to be

dealt with most cautiously, for too great a reliance on them has led to the propagation

of gross errors.

Jahrb. ii. (1882) pp. 136-176 and 395-424 ; and as the result of more extended obser-

vation and investigation, he considerably modifies the limits of some of the species. Two

or three of the forms described by us as new species he has identified with previously

described species, or regards as forms of such. Thus C. anisophylla, Hemsl., is referred,

together with several other forms, including C. orthodisca, Koehne, to C. calophylia, Ch.

et Schl., a very variable species extending into Brazil; the specimens we referred to his

C. palustris he regards as C. procumbens, Cav.; C. minuta he reduces to a variety of

C. lavea; C. propingua, Hemsl., and C. ternata, Peyr., are referred to C. heterophylla,

Benth. ; and C. dodecandra, Hemsl. {, is the same as C. subuligera, Koehne. Further,

there are three additional species.

can hardly be of this genus.”—A. Gray.

There is a specimen in Kew Herbarium of Andrieux’s 286, upon which De Candolle

founded this species, and there is no doubt it belongs to the genus Palafozia as limited

by Bentham and Hooker, and to Polypteris as restored by Gray himself; therefore

Polypteris latifolia, Hemsl. Indeed it is very near P. lindeni, A. Gr., which.has the

lower leaves strictly opposite, like P. latifolia.

In a revision (Proc. Am. Acad. xix. p. 93) of the North-American species of this

and Botteri’s 583 and 794 to our B. mexicana; and he doubtfully adds 2B. disticha,

H. B. K., to the Mexican species (Ghiesbreght, 8260), with B. tinctoria, Bertol.?, for a

synonym.

[ii. p. 468.] CONOPHOLIS.

Until it was too late we had overlooked the publication by Liebmann of two new

species of this genus; and since the appearance of that part of our work containing

Conopholis, S. Watson, on the authority of an herbarium specimen named C’. mexicana

by A. Gray, has published a new species for some at least of the Mexican specimens in

the Harvard herbarium. We must leave unanswered the question of. the number of

species of Conopholis in Mexico; but as Liebmann’s descriptions were published in a

book that has been entirely overlooked in this country and America, and is very rare,

it will be useful to repeat them here.

78 SUPPLEMENT.

[ii. p. 468.] Conopholis alpina, Liebm. in Forhandl. Skand. Naturf. 4de Made,

p- 184.

“ Calyce unibracteolato, ventricoso-tubuloso, spathaceo, antice usque ad basin fisso, postice acuto,.

margine integro. Corolla tubo cylindrico curvato, labio superiore reflexo fornicato integro

inferius equante ; labio inferiore 3-lobo, lobis rectis lanceolatis. Staminibus 4 exsertis sub-

eequalibus stylo zequantibus vel parum brevioribus. Stigmate discoideo medio impresso.

“ Planta 6-8-pollicaris. Caulis simplicissimus carnosus crassus fusco-brunneus, basin versus incras-

satus ibique squamis densissime imbricatis tectus, supra squamis majoribus sparsis obtectus ;

spica 8—4-pollicaris, floribus sessilibus fusco-flavescentibus.

«“ Habitat in alpe trachytio Tepeyecuapa prope oppidum Chinantla, Puebla, alt. 7000-

8000 ped., ad radices Pinorum. Floret Aprili.

“ Differt a Conoph. americana, Wallr., calyce unibracteolato, ad basin fisso, postice

non inciso; corolla calyce duplo longiore, labio superiore reflexo integro lobos labii in-

ferioris non superante ; labii inferioris lobis brevioribus lanceolatis integris ; staminibus

longius exsertis ; stylo longitudinem staminum parum excedente angulato porrecto (non

reclinato); capsula apiculata (nec curvato-longirostrata), bractea breviore integra (nec

bifida) instructa.”

This probably corresponds to C. mexicana, A. Gr., as limited by Watson ; but the

differential characters given are not obvious.

[ii. p. 468.] 1*. Conopholis mexicana, A. Gr. in Herb. ex S. Wats. in Proc.

Am. Acad. xviii. p. 131. |

“Distinguished from C. americana by its longer and more rigid lanceolate acu-

minate scales, the calyx less deeply toothed, and the corolla larger (8 lines long).

“The plant figured by Endlicher (Iconogr. t. 81) for C. americana is C. mexicana,

probably from Andrieux’s collection.”

As Watson observes, possibly from a memorandum by A. Gray, Endlicher’s figure

was most likely made from Andrieux’s collection, for there is a specimen in the Kew

Herbarium (formerly in Gay’s herbarium) collected by Andrieux, which is so like the

figure that it may have been the one actually drawn.

[ii. p. 468.] 1**. Conopholis sylvatica, Liebm. in Forhandl. Skand. Naturf.

inferiore 3-lobo, lobis brevibus rectis obtusis. Staminibus 4-exsertis, subequalibus stylum

“Planta 7—9-pollicaris gracilescens. Caulis simplicissimus carnosus flaccido-fucescens, usque ad

The specimens in Kew Herbarium from Jalapa (Linden, 198) and Vera Cruz to

Orizaba (Miller, 647) answer well to the foregoing description as to slenderness, and in

being cylindrical to the base.

COZUMEL ISLAND.

ENUMERATION OF A SMALL COLLECTION OF PLANTS MADE IN 1885

BY F. GAUMER*.

Tuts island is about twenty-five miles long, and about twelve miles from the coast

of Yucatan, and the highest ground is not more than a few hundred feet above the

level of the sea. As Mr. Gaumer is a zoologist rather than a botanist, it is uncertain

to what extent the present collection represents the vegetation of the island; but from

the nature of the collection generally, it may be assumed that it is a very good sample

of the vegetation, and not a mere selection. An analysis follows the list. The species

followed by a W. are found in the West Indies.

“Not common” (Gaumer).

In all particulars except the number of ovules this is very closely allied to the large-

flowered Sapranthus nicaraguensis, Seem. [see vol. i. p. 14], which, at the suggestion

of Professor Oliver, we here reduce to Asimina, as A. nicaraguensis. Asimina triloba

and other North-American congeners differ mainly in having axillary flowers and more

numerous ovules. Whether Porcelia, Ruiz and Pavon, should be referred to the same

genus we leave undecided; in any case, Adanson’s Asimina is the older. Baillon

(‘ Histoire des Plantes,’ i. p. 199) unites these genera as a section of Uvaria. Uvaria

hahniana, Baill., is probably of this affinity .

* This collection was presented to the Kew Herbarium, and Professor D. Oliver determined the whole of

the plants as far as he could without much critical research; but Mr. Hemsley takes the responsibility of

describing those believed to be new.

+ Since the above was put in type, Dr. Asa Gray has published (Coulter’s Bot. Gaz. 1886, p. 161) a revision

of the genus As¢mina, in which he takes a very different view of its limits, and retains Sapranthus as an

independent genus.

Altogether there are 140 flowering plants and one fern, and of these 141 species,

ninety are common to the West Indies and Mexico, or Central America; nineteen,

including five doubtful ones, occur on the mainland, but are not known to be West-

and twelve of them are essentially West-Indian species, not known to occur

on the mainland, at least neither in Mexico nor in Central America. Then there is

one south-eastern North-American species and four Old World colonists, leaving fifteen

not identified with any described species, though half of these are perhaps not specifi-

cally distinct from known plants, the specimens being imperfect. Even those described

as new species may exist on the opposite mainland, for very little is known of the

vegetation of Yucatan. Taking present data, however, the Flora of Cozumel is probably

more West-Indian than continental American in character; for, although the number

of species, excluding doubtful ones, common to Cozumel and the continent but not

found in the West Indies is somewhat larger than the number of West-Indian species

found in Cozumel but not on the mainland, those of the latter category are of a more

distinct type than those of the former. Thus Rhachicallis and Ernodea are very distinct

monotypic genera—the former ranging from the Bermudas and Bahamas to Cuba and

Jamaica, and the latter from Southern Florida and the Bahamas to Guadaloupe and

Jamaica. Rhus metopiwm, which with one other Cuban species Engler has recently

raised to the rank of an independent genus, is only West-Indian and Floridan ; Trichilia

terminalis, is a common tree in Jamaica, not recorded from elsewhere; and Ambrosia

hispida and Euphorbia trichotoma are decidedly well-marked species restricted to the

Floridan and West-Indian region ; while the remainder are doubtful or less distinct.

It is true that the majority of the plants named are essentially littoral. On the other

hand, there is not one continental genus represented in the flora of Cozumel, so far as

is known, which is not likewise West-Indian. Sambucus at first seemed to be a note-

worthy exception, as the genus does not appear in Grisebach’s ‘Flora of the British

West Indian Islands,’ nor, apparently, in any other record; but on looking through the

Kew Herbarium a specimen of a species of Sambucus was found labelled “ St. Vincent,

Rev. L. Guilding.” It may or may not be the same species as that from Cozumel, and

there is a possibility of a mistake, as there is no original label. The New World range

of Sambucus is from Canada to North Florida and California, through Mexico and the

Andes to Chili, South Brazil, and Buenos Ayres.

In composition Mr. Gaumer’s collection of Cozumel plants offers almost a parallel to

Professor Moseley’s collection from Fernando Noronha*, probably owing to similar

causes. Gaumer found only one species of fern—a form of the almost ubiquitous Pteris

aquilina—Moseley none; Gaumer two or three petaliferous monocotyledons and five

grasses and sedges—Moseley no petaliferous monocotyledons, but two or three more

grasses. As in most insular floras, the proportion of genera to species is high in

Cozumel: thus the 141 species belong to 121 genera and fifty-four natural orders. The

only genera represented by more than two species are: Jpomea, Solanum, and

Euphorbia. Among the plants described as new, Bravaisia tubiflora is perhaps the

most interesting, as it is the second species of the genus, the other ranging from Mexico

to Peru and also occurring in Trinidad ; and the new species is the same as a specimen

collected by Hahn at “ Tlacatalpan,” probably Tlacotalpan, near the coast, in Vera

Cruz.

fruit it is impossible to be sure on this point. The collection was presented by Mr. Godman to the Kew

COSTA-RICAN FERNS.

On page 589 of the third volume of this work it is stated that the Kew Herbarium

contained only about fifty species of Ferns from Costa Rica. That number has now

been increased to 134 by a collection made by Mr. J. J. Cooper, and communicated to

Kew by the Trustees of the National Museum, Washington, U.S. This collection of

Ferns was obligingly offered to the writer for the purposes of this work, and, as

Mr. Baker kindly undertook to name them, the offer was accepted, on the condition

that Kew received the first set. Independently of four new species, there are fifteen *

in the following list not previously recorded from any part of our territory ; but as the

summary and analysis of the flora was all written before the names of this collection

were available, they are not included therein. To add them now would involve the

alteration of many figures, some of which would almost certainly escape notice; and

such alterations would not materially affect any question concerning the general distri-

bution of Ferns; therefore it appears better to be content with a cross reference to this

APPENDIX.

PRELIMINARY REMARKS.

Now that the laborious Enumeration has been brought to an end, we have to enter

upon the more congenial portion of our task relating to the distribution of the plants.

This might be approached from a variety of aspects, and it might be extended almost

indefinitely, especially in the examination and discussion of the various theories put

forward by different writers; but, as it is the intention of the Editors to publish an

Introductory Volume at the conclusion of the much more extensive zoological portion

of the work, embracing the whole subject, we shall confine ourselves almost exclusively

to an exposition of the facts. For the same reason the physical geography and

climatology will only be dealt with in a very general way, and the geology will not be

touched. But while these subjects have been either altogether neglected or very

briefly treated, the distribution of the plants has been almost exhaustively tabulated

and analyzed. In the tedious process of compiling the tables and collecting the

materials for the various sections of this Appendix, the writer has been very ably

assisted by Miss Matilda Smith. The figures have almost invariably been obtained

by one and checked by the other, and thereby it is hoped that serious errors have

altogether been avoided. It is important to note that the geographical tables were

not literally compiled from the Enumeration, otherwise persons using the work would

find themselves confronted with numerous unaccountable discrepancies; but the nature

and extent of the eliminations and modifications made are explained in the paragraph

preceding the first of the tables.

As each section of the present’ Appendix contains all that seems necessary to make

it intelligible in itself, it is unnecessary to enter into further particulars here, especially

as the object and scope of the work are set forth in the Preface to the first volume, and

the contents of the present volume are fully summarized at the beginning.

A SKETCH OF THE HISTORY OF THE BOTANICAL EXPLORATION

OF MEXICO AND CENTRAL AMERICA.

‘THIs must necessarily be brief and imperfect; but the subject could not properly be

omitted altogether. Francisco Hernandez, physician to Philip II. of Spain, was the

first European who investigated the flora of Mexico, though from a medicinal rather

118 APPENDIX.

than a botanical standpoint *. He spent six years in Mexico, chiefly in the State of

Mexico, from 1571 to 15777, and must have worked most assiduously; but the

greater part of the fruit of his labours was destroyed in the great fire at the Escurial

in 1671. Fortunately, however, his manuscripts relating to plants and animals escaped,

and were published, or some portion of them, in 1615 {. We have not seen this work,

of which, according to Pritzel §, there is a copy in the Imperial Library at Vienna ; but

of the much fuller and more interesting ‘Rerum Medicarum Nove Hispanie’ |,

published in 1651, there is an excellent copy at Kew. This is a folio book of about

a thousand pages, containing numerous woodcut illustrations of plants and animals,

chiefly of the former, and mostly recognizable, and some very good. Conspicuous

among the flowers in the ornamental head- and tail-pieces are Tigridia, Cheirostemon,

and the famous “Flos Lyncei,” probably Stanhopea tigrina. These singular forms

must have greatly excited the curiosity of those interested in flowers, long before any

attempt was made to introduce living plants of them into European gardens. Many

years after the publication of the work described, five manuscript volumes of Hernandez’s

works, containing many corrections in the handwriting of Hernandez himself, were

found in the library of San Isidro, Madrid, and those relating to botany were published

under the superintendence of Gomez Ortega in 17904. As this work is not illus-

trated it is less intelligible than the ‘Rerum Medicarum.’

Proceeding with this history in chronological sequence, or as nearly so as our data

will permit, Dr. William Houston, F.R.S., appears to be the next person deserving

notice here on account of his connexion with Mexican botany. He studied during

two years at Leyden, under Boerhaave **, from whom, probably, he imbibed a taste

for botanical pursuits; and on going to the West Indies in 1729, and later to Mexico,

he sent seeds of numerous plants to Philip Miller, the “ Hortulanorum Princeps” of

his time, and Superintendent of the Apothecaries’ Garden at Chelsea, where he raised

and cultivated many of the plants thus introduced. Houston’s name is frequently

mentioned in Miller’s incomparable ‘Gardener’s Dictionary’ as the collector of plants

therein described; but more conspicuous evidence of his activity exists in John

Martyn’s ‘Historia Plantarum Rariorum’ (1728-1732), “the most sumptuous and

magnificent work of the kind that had ever been attempted in England.” In this

work are coloured engravings of the genera Gronovia, Milleria, Martynia, and Turnera,

various species of Passiflora and other plants, introduced, as we are informed, by

Houston. This was just before the publication of Linneus’s binominal nomenclature ;

but the Linnean names were subsequently added on a flyleaf at the beginning of the

volume. During his short sojourn in the West Indies, from 1728 to 1733, when he died

a victim to the climate, Houston drew up a catalogue of the plants he had collected,

wrote a treatise on contrayerva, jalap, and other Mexican medicinal plants, and

engraved with his own hand analyses of the flowers and fruits of various new genera,

after the manner of Plumier *. These engravings passed into the possession of Miller,

who sent copies of them to Linneus; and later, after Miller’s decease, they were

purchased by Sir Joseph Banks, and published by him in 1781 under the title

‘Reliquiee Houstoniane.’ They mostly represent Mexican plants, and they bear the

names given to them by Linneus. MHouston’s dried specimens are in the British

Museum.

In continuing this sketch, it will save space and unnecessary repetition of various

particulars if some of the minor collectors are mentioned under those of the first

rank of about the same period ; hence that course will be adopted, where practicable.

Iwis Née—A Frenchman, naturalized in Spain, and one of the botanists who

accompanied Malaspina on his voyage round the world. He was a most indefatigable

collector, and was endowed with considerable scientific ability. On the authority of

Colmeiro, Née was the first to make the interesting discovery of the existence of Rhodo-

dendron ponticum in the Iberian peninsula. Malaspina’s voyage was made during the

years 1789 to 1794, and when Née landed at Cadiz he had made a collection of dried

plants estimated at 10,000 species, including 4000 new to science. Like many other

fine collections made by Spanish naturalists, it has been permitted to lie at Madrid

unused. ‘There were also upwards of three hundred drawings by various artists.

Thaddeus Henke, a Bohemian by birth, was also to have accompanied Malaspina ;

but he arrived at Cadiz twenty-four hours after the ship had sailed. He followed in

another ship, hoping to find Malaspina at Monte Video or Buenos Ayres, failing which

he traversed the American continent to Chili, where he fell in with Née, and the two

subsequently botanized together in various parts of the world, including Mexico tf.

* Rees’ Cyclopedia.

+ Presl, ‘ Reliquie Hankeane,’ i. Pref. p. xi, has the following note with reference to the Mexican journey:—

“‘Mense Novembri profectus est Thaddeus Henke solus ad urbem capitalem Mexico, et Decembri reversus est

ad Acapulco. Fructus hujus itineris consistit quinque fasciculis quibus verba: Iter Mexicanum et Plante

Mesxicane inscripta sunt.”

120 APPENDIX.

They travelled from Acapulco to the city of Mexico, though it would appear that

they did not diverge much from the beaten tracks. Hznke’s plants are in the Prague,

Vienna, and other continental herbaria. Presl elaborated these collections in two illus-

trated volumes entitled ‘ Reliquie Henkeane.’ Some of the types are in the British

Museum, and a few, chiefly Cyperacew, at Kew; the latter formed part of Bishop

Goodenough’s herbarium, recently presented to Kew by the Corporation of Carlisle.

Martin Sessé.—A Doctor of Medicine and a botanist, who was made leader of an

expedition for the scientific exploration of New Spain, sent out in 1795 by Charles IV.

of Spain. José Mariano Mocifio and Vicente Cervantes were associated with him in

this work. The latter afterwards became Professor of Botany at Mexico city, where

he died in 1829 at the age of seventy years *. He was the first who publicly lectured

on botany in Mexico ; and he appears to have kept up a correspondence with European

botanists, among whom was Lambert; for we find that several Mexican plants were

raised in Lambert’s garden from seeds sent by Cervantes—occa latifolia (Lagascea)

in Sweet’s ‘ British Flower Garden,’ series 1, plate 215, for example. Sessé and Mocifio

spent eight years, from 1795 to 1804, in the botanical exploration of Mexico and the

adjoining countries, from Punta Arenas in Costa Rica to the mouth of the river

Hiaqui or Yaqui in north-western Mexico; afterwards visiting California and the

West Indies. This expedition seems to have: been conducted with great skill, industry,

and devotion ; yet to this day the results have not been published, except a few frag-

ments, and these by foreigners. The fruit of these journeyings, Colmeiro states, was

a considerable herbarium, which reached the Madrid botanic garden in 1820, and was

incorporated in the general collection. “ There was also a fine set of about 1400

coloured drawings of Mexican plants, executed by Atanasio Echevarria, a Mexican,

and Juan de Dios Cerda, both clever artists whose names are commemorated in the

genera Hcheveria (now a section of Cotyledon) and Cerdia, a singular genus of the

Caryophyllaceze recently rediscovered by Parry and Palmer in San Luis Potosi.!! By

some means a small portion of Mocifio and Sessé’s herbarium came into Lambert’s

possession, and at his death it was purchased for Delessert. During the time these

plants were in Lambert’s possession David Don described a number of them, including

the genus Cowania and various Composite}. It is conjectured, too, that the large

number of Mexican plants in Pavon’s collections at Kew and the British Museum

formed part of Mocifio and Sessé’s herbarium {. This is very probable, as Pavon

himself was never in Mexico, and there is evidence of his having dealt freely in the

sale of dried plants.!’Through Mocifio, the collection of drawings alluded to, and

various manuscripts, passed into the hands of the elder DeCandolle for publication,

and 271 species, including seventeen new genera, were founded on the drawings alone.

Shortly before his death, and somewhat unexpectedly and peremptorily, Mocifio

requested that the drawings should be returned to him. How the whole of them

were copied, with the assistance of about a hundred ladies, in ten days, is a matter

of history. Since then, through the generous consideration of Mr. Alphonse DeCandolle,

the principal botanical establishments have acquired tracings of all the drawings on

which published species had been founded, except a few which had previously been

engraved for some of the ‘Mémoires’ of A. P. DeCandolle. A copy in the Kew

Library has been of the greatest service in determining many doubtful species. })

In the Kew herbarium is a small collection of Mexican plants presented to the late

Sir William Hooker by a person named Tate, probably Mr. Tate, a nurseryman of

Sloane Street, London, who, early in the present century, was an enterprising cultivator

of Mexican plants obtained through various channels. It is probable that the dried

plants in question were received from Mocifio; we say probable, because they corre-

spond to plants described by DeCandolle from Mairet’s herbarium, concerning which

we believe it is somewhere recorded, though we cannot recollect where, that Mairet

came into possession of some of Mocifio’s dried plants. The Kew specimens in question

are accompanied by labels bearing the same manuscript names cited by DeCandolle

from Mairet’s herbarium, though not the same numbers. Senecio vernus, De C., is an

example, the manuscript name being Cimeraria vernix, which was probably converted

into vernus by a slip of the pen, especially as the latter name has no particular appli-

cation to the plant, and the former has.

Alexander Humboldt and Aimé Bonpiand.—The great scientific expedition led by

the master mind of his time is too well known to need much more than passing

reference here. It was entered upon in 1799 and terminated in 1804—the materials

amassed being sufficient to occupy a long and active life, to say nothing of the labours

of others. In several branches of inquiry we are still no further advanced than he

was, though his Mexican botanical collections were comparatively small, amounting,

according to Kotschy *, to 956 species belonging to 380 genera. ‘These, as we learn

from the authors themselves f, were collected within a period of ten months, and in

parts of Mexico lying between the seventeenth and twenty-first parallels of latitude.

The routes and regions are, briefly :—1. Western slopes of the Mexican Andes, from

the shores of the Pacific Ocean to Lake Tezcuco; 2. Elevated Plains of Mexico,

temperate and frigid regions, from the valley of Mexico by Anahuac, El Baxio, and

Michoacan to the mines of Guadalajara; 3. Eastern slopes of the Mexican Andes,

from Perote to the Atlantic Ocean. A fuller explanation will be found in the work

* “ Ueberblick der Vegetation Mexicos” (Sitz. Ber. Akad. Wiss. Wien. viii. 1852).

cited, together with the various excursions made from the main routes, and the names

and altitudes of all the principal localities, temperatures, &c.

Bonpland was the actual collector of the plants. He was born in 1773 at La

Rochelle, where his father practised as a doctor *. The son was educated for the same

profession, and on going to Paris to complete his studies he there became acquainted

with Alex. v. Humboldt in 1798. Subsequently they undertook their famous expe-

dition to America, which is described by Humboldt under the title ‘A Journey to

the Equinoctial Regions of the New World.’ Bonpland collected more than 6000

species of plants during the expedition, which he afterwards presented to the Museum

at Paris. Napoleon, in gratitude, awarded him a pension, and he was made Steward

to the Empress Josephine at Malmaison.. In 1816 he decided to settle in America,

and went to Buenos Ayres, where he was made Professor of Natural History. After

some time he resolved to undertake a journey over the Pampas, to Santa Fé, Gran

Chaco, and Bolivia, for the purpose of further exploring the Andes; but he was stopped

by Dr. Francia, then Dictator of Paraguay, and kept a prisoner at Santa Maria for more

than nine years, till 1831. On his release he settled at San Borja in Corrientes,

and devoted himself to cultivating his estates and to making short excursions from

time to time into La Plata &c. for natural-history purposes. In 1849 he received the

Cross of the Legion of Honour, was made Head Director of the Natural-History

Museum of Corrientes, and died at San Borja in 1858, leaving his collections, books,

and manuscripts to the French Marine Ministry.

An interval of twenty years elapsed between the visit of Humboldt and Bonpland —

and the next Europeans on our list who visited Mexico for the express purpose of

investigating its natural history. In point of date, however, a native of Mexico

occupies the next place.

Juan Lexarza, a native of Valladolid, in Michoacan, Mexico, was born in 1785, and

after he had grown up he became acquainted with Pablo La Llave, a Spanish priest,

distinguished for his knowledge of botany, who gave him his first instructions in this

science. In 1824-25 they published conjointly a number of new genera of Mexican

plants, mostly named after eminent contemporaries, and a number of orchids, chiefly

natives of the State of Michoacan; Lexarza being the principal author, and the sole

author of a new classification of orchids, based upon their seeds and pollen. This is

reproduced in the ‘ Bonplandia’ for 1856, p. 26. Lexarza gave promise of making an

accomplished botanist, but he attempted too much and was cut off young. Several of

his orchids have not been identified in consequence of the descriptions being imperfect.

David Don mentions having received a small collection of dried plants from

Don Pablo La Llave, by which he became acquainted with the genera of Com-

posite described in the ‘ Descriptiones Novorum Vegetabilium.’ -These plants formed

a part of Lambert’s herbarium, which was subsequently dispersed in small lots; some

having been purchased for continental museums. |

In 1825 a new period of activity set in, and continued almost unbroken for many

years; but few of the numerous travellers had received a scientific training, hence the

botanical results were by no means so satisfactory as they might have been. Indeed,

the principal object of many of these travellers was the introduction of living plants

into European gardens.

Carl Sartorius left Darmstadt in 1825 or 1826 on account of political disturbances,

and took refuge in Mexico, where in 1830 he bought some land at Mirador, at the foot

of the Orizaba mountain-chain, and devoted himself to its cultivation. He made large

collections of plants at every opportunity, and on his death in 1872, on his Hacienda at

Mirador, he left his herbarium to the Smithsonian Institution at Washington. He was

soon followed by several others. Here and there we find a plant in the Kew Herbarium

collected by Sartorius, and acquired in exchange from Berlin.

Withelm Friedrich von Karwinski, a Bavarian naturalist, who had already travelled

in Brazil, was sent to Mexico in 1826 by the German-American Mining Society of

Dusseldorf and the Bavarian Government, to make collections of objects of Natural

History. He remained five years, chiefly in the province of Oaxaca, and sent home

great numbers of living plants (especially Cactaceze and Agaves) from there and from

Ismiquilpan, Zimapan, &c. In 1840 he again visited Mexico for the Russian Govern-

ment with the same object, returning to Munich in 1843, while his collections were

sent to St. Petersburg.

Jean Luis Berlandier, a native of Ghent, proceeded to Mexico about the same date

as the last-named traveller, and made considerable collections in the North-eastern

States of Tamaulipas, San Luis Potosi, Nuevo Leon, and Coahuila, between 1827 and

and 1830; but his largest collections were made at a later date in Texas. He died at

Matamoros in 1851. There is a set of his plants in the Kew Herbarium, but from the

vagaries in the numbering it is impossible to judge whether it is complete or otherwise.

Christian Julius Wilhelm Schiede, a Doctor of Medicine, was accompanied by

Ferdinand Deppe in an expedition to Mexico in 1828, the latter having previously

visited the country alone. Starting from Vera Cruz they explored all the neighbour-

hood of Jalapa, ascended Orizaba, and in the cold season visited Papantla and Misantla,

making large collections of plants &c. There is a small set of their plants in the Kew

Herbarium, labelled, we believe, in Schiede’s handwriting ; but the first set is at Berlin.

Schlechtendal, who, in conjunction with Chamisso, described a large number of the

r2

124 APPENDIX.

plants in the fifth and succeeding volumes of the ‘ Linnea,’ also possessed a good set at

Halle. Schiede himself contributed to the same serial (vols. iv. and v.) a number of

interesting letters on the general aspects of the vegetation of the parts visited.

Hegewisch and Muehlenpfordt, two Germans, collected at about the same time, and.

some of their plants were described by Chamisso and Schlechtendal with Schiede and

Deppe’s. Dr. Schiede settled in Mexico, where he practised medicine up till his death

from typhus in 1836.

The Voyage of H.M.S8. * Blossom. —This expedition, under the command of Captain

F. W. Beechey, touched at San Blas in December 1827, and remained until the following

February ; and Mr. Lay, the naturalist, spent a long time at Tepic, about fifty-four miles

inland, where he made a collection of dried plants, containing most of the new species

described by Hooker and Arnott in their ‘Botany’ of the voyage, throughout which

Jalisco is misprinted Talisco. Later they proceeded to Mazatlan and Acapulco, where,

however, they staid only a very short time. Mr. Collie and other officers of the ship

assisted in collecting, and in our Enumeration sometimes the names Lay and Collie

are coupled ; but more frequently the plants of this expedition are assigned to Beechey,

in consequence of their having been so labelled in the Hookerian herbarium. The

Kew set is not quite complete.

George Ure Skinner—This gentleman first went to Guatemala in 1831, and he

speedily gave a new zest and impetus to the cultivation of orchids in England by the.

introduction of living plants of a large number of very showy kinds. He was the second

son of the Very Rev. John Skinner, Dean of Dunkeld and Dunblane, and was born in

1804*. Skinner’s energies, outside of his business, were mainly devoted to orchids,

especially to the exportation of living plants to England, but he did not neglect other

subjects, having been the first to send many of the peculiar Guatemalan birds to this

country. He also greatly aided naturalists who visited Guatemala during his long,

though often interrupted, residence in the country. There is a small general collection

of dried plants collected by him in the Kew Herbarium ; it is probable, however, that

this is not the first set, which may be in the Lindley herbarium at Cambridge ; still, he

concerned himself more with living than dried plants. It is estimated that he intro-

duced living plants of nearly one hundred species of orchids—a great achievement in

those early days of plant-importation. A large proportion of them was previously

unknown to science. It would be out of place to enumerate here the many gorgeous

species Skinner discovered, but it may be mentioned that he was the first to introduce

a living plant of an Odontoglossum into England. In 1866 he decided to retire from

business, and started for Guatemala, with the intention of winding up his affairs,

But at Panama, on his outward journey, he was smitten with yellow fever and died.

. * Gardener’s Chronicle, 1867, p. 180.

HISTORY OF BOTANICAL EXPLORATION. 125

Had he been spared to carry out his plan of settling down in England he would have

crossed the Atlantic forty times! Many of Skinner’s discoveries adorn Bateman’s

gigantic book on the orchids of Mexico and Guatemala.

Thomas Coulter—Dr. Coulter collected in California from 1831 to 1833, and then in

Sonora, and was the first from whom we have specimens of the botany of North-western

Mexico. He also collected largely in Zimapan and Real del Monte, where he was

Surgeon to one of the Mining Companies; but this appears td have been previous to

his visit to California. His collection went to Trinity College, Dublin, where Coulter

preceded Dr. Harvey as Curator of the herbarium. After Coulter’s death in 1843,

Harvey distributed the duplicates of the collections, and the first set is at Kew.

G. Andriewe.—An excellent collector of Mexican plants, concerning whom we have

been able to find no particulars beyond the fact that he sent dried plants, collected in

the States of Oaxaca, Puebla, and Mexico, to Delessert before 1835. The Hookerian

herbarium contained a set of Andrieux’s plants; but Gay’s herbarium, purchased by

Sir Joseph Hooker, included a much fuller set, inscribed “Dedit Andrieux, 1834.”

The plants appear to have been very carefully sorted and numbered, hence it was not

difficult to determine those that had been described by DeCandolle and others.

Henri Galeotti ; August Ghiesbreght ; Jurgensen ; Jean Jules Linden; Nicolas Funch.

—From 1835 to 1840 Mexico was the scene of great activity among botanical and

horticultural collectors. The names we have grouped here belong to Belgians, or to

collectors sent out under Belgian auspices; and they collected more or less in company

during some portion of their sojourn in Mexico. Galeotti was a native of Versailles, where

he was born in 1814; and in 1835 he left Hamburg for Mexico under the patronage of

a Mr. Vandermalen. He spent five years there, collecting chiefly in the States of Vera

Cruz, Mexico, and Oaxaca ; and his collection of dried plants was estimated at 7000 to

8000 species *. With the assistance of various botanists, chiefly of Martens of Louvain,

a large portion of the collection was elaborated, though not in all cases very critically.

Starting from Vera Cruz, Galeotti first visited Jalapa, and during a stay of six months

was able to collect many living plants, especially orchids. He next explored the plains

of Perote to Puebla as far as the base of the volcanic chain of Iztacihuatl ; he also

botanized in the plain of Mexico three several times, ahd in 1836, accompanied by

Mr. Ch. Ehrenberg, of Berlin, travelled for two or three months among the mountains

of Real del Monte. Later he visited the Western Cordillera of Mexico, Guadalaxara,

and Lake Chapala, and made a rapid journey to San Blas on the shores of the Pacific.

In 1837 he went to Guanajuato and the Volcan de Popocatepetl, bringing thence a

collection of plants from the highest limits of vegetation. He also ascended to the

126 APPENDIX.

summit of Campanario, Nevada of Toledo, 15,000 feet altitude, and explored Michoacan,

Jesus del Monte, Santa Maria, Patzcuaro, Jorullo, and Uruapan, as far as Guadalaxara.

In December of the same year he went north to San Luis Potosi, and on his return |

visited Mirador and Zacuapan. Accompanied by his friends Funck, Ghiesbreght, and

Linden, he next ascended the peak of Orizaba, living for eleven days in a cavern,

situated at about 11,000 feet, whence they collected between three and four hundred

species of plants at elevations between 9000 and 12,000 feet. In 1839 he went to

Tehuacan, Oaxaca, the Cerro de San Felipe, &c., in the Eastern Cordillera of Oaxaca

and Chinantla, and on his return explored the Misteca Alta, Pefioles, laltepec, &c.,

leaving Mexico in 1840; and on his return he was rewarded for his services to science

by being made a member of the Académie Royale of Brussels. Jurgensen collected for

Galeotti after the latter returned to Brussels and established himself as a nurseryman.

Nearly the whole of his plants in the Kew Herbarium are uniformly labelled “ 'Talea,

Sierra San Pedro Nolasco,” &c. Ghiesbreght travelled with Linden and Funck in

Mexico from 1837 to 1839, when he came home, returning alone to Mexico in 1840

for the purpose of more thoroughly exploring the country. He visited both the

southern and northern States; crossed the great chain of the Cordilleras from ocean

to ocean three times; traversed the vast plateaus, and ascended the volcanos of Colima,

Jorullo, and Sempoaltepec. Ghiesbreght subsequently made considerable collections |

in Chiapas. Linden first went to Yucatan, and thence to the States of Chiapas and

Tabasco; visiting and exploring the districts of Ciudad Real, Cacaté, San Bartolo

Jitotoli, Santiago de Tabasco, Teapa, Puyapatengo, &c., where he formed by far the

largest collections we have seen from those parts of Mexico. Linden afterwards

became the possessor of the famous nurseries at Ghent previously held by Verschaffelt,

and is, we believe, the only survivor of that band of collectors, to say nothing of

numerous others of later date, who so largely added to our knowledge of the botany of

Mexico. As our Enumeration testifies, Kew possesses very full sets of all except

Funck’s collections.

About the year 1836 Don Joaquin Velasquez, who was attached to the Mexican

Legation at Rome, came to Europe, bringing with him seeds and dried specimens of

various Guatemalan plants, which formed the basis of Bertoloni’s ‘ Florula

Guatemalensis.’

Theodor Hartweg; G. J. Graham.—Hartweg collected in Mexico during the same

period as Galeotti and his companions, having been sent out by the Horticultural

Society of London in 1836, though it does not appear that he fell in with them. The

principal object of his journey was to collect and transmit living specimens or seeds of

ornamental plants and trees ; but he also made large collections of dried plants, the

numerous novelties of which were published by the late Mr. George Bentham between

1839 and 1842, under the title of ‘Plante Hartwegiane.’ Hartweg landed at Vera Cruz

HISTORY OF BOTANICAL EXPLORATION. 127

in 1836, and proceeded thence to Santa Fé and Zacuapan, which is situated at an

elevation of about 3000 feet, and, where, he states *, he encountered the richest vege-

tation he ever saw in Mexico. His sketch of the flora of the various regions he passed

through agrees in its main features with that of Richard and Galeotti, which we else-

where reproduce in a condensed form, varying only in its details, and being altogether

very interesting reading. Hartweg’s destination was Guanajuato, whither he journeyed

by way of Jalapa and Mexico. His first excursion was to El Gigante, the highest point

in the mountains of Guanajuato, where the vegetation is of a cold temperate type,

such genera as Garrya, Arctostaphylos, Berberis, Ribes, Arbutus, and Quercus abounding,

but Pinus was nowhere to be found. The next places visited were Leon and Lagos in

Guadalajara, where the country was parched and barren at that season, June and J uly ,

accordingly Hartweg proceeded northward to Aguas Calientes, and thence westward to

Bolafios, where the vegetation is quite of the North-Mexican character; Bromeliacee,

Cactacese, various species of Agave and kindred plants predominate, and above them

Oaks and Pines, Arbutus, &c. Zacatecas, San Luis Potosi, Los Gallitos, were next

successively visited, and the first place a second time; whence the journey was

continued to Guadalajara and back to Bolafios. This region proving almost fruitless

for his purposes, Hartweg went direct to Morelia, the capital of Michoacan, a country

of epiphytes and showy herbaceous plants. After two months’ stay in this interesting

country Hartweg went to Anganguia, Real del Monte, the Barranca Grande of Mextitlan,

from its chalky soil “a favourite haunt for Cactacee,” Cereus senilis attaining a height

of twenty-four feet, and northward to the barren pine-hills of Zimapan. It was now

the beginning of 1839, and he received instructions to go on to Guatemala. To this

end he went to Mexico, and there made the necessary arrangements for an overland

journey thither, travelling by way of Oaxaca, Las Cruces, Llano Verde, Comaltepec,

Totontepec, and returning to Oaxaca, whence an excursion was made to Chinantla;

subsequently journeying direct to Guatemala through Comitan, Huehuetenango, Que-

zaltenango, Retalhuleu, Totonicapam, and Mixco to the city of Guatemala. Hartweg

here met with Skinner, who accompanied him on several of his excursions in search of

orchids. The Volcan de Agua was climbed, and a considerable number of plants

collected ; but it was reserved for Salvin and Godman to more fully explore this peak

botanically, as well as the neighbouring Volcan de Fuego. After making a few other

short excursions in Guatemala, Hartweg proceeded beyond our limits to the equatorial

Andes.

In connexion with Hartweg’s collections it should be mentioned that in the earlier

part of our Enumeration some of the species are recorded from two places, owing to

their having been incorrectly localized in the Hookerian herbarium. The first and

Hest set at Kew formed part of the Benthamian herbarium, and the localities given

these may be taken as correct. Respecting the Mexican plants attributed to

Graham, Bentham has the following note * :—‘* To these plants [%. e. Hartweg’s] I have

occasionally added notes on another most valuable set of above 400 bé&utifully dried

Mexican species gathered about the town of Mexico and in the mining districts of

Tlalpuxahua and Real del Monte, and presented to me some years since by G. J. Graham,

a gentleman whose name must be well known to horticulturists from the number of

handsome Mexican plants he was the means of introducing into this country, and whose

zeal in collecting specimens, and liberality in disposing of them, equally entitle him to

the gratitude of botanists.”

Karl Ehrenberg.—A collector and botanist who spent ten years in Mexicof in

the States of Oaxaca, Mexico, San Luis Potosi, &c., and paid special attention to’

the Cactacez, of which he introduced large numbers into European gardens. He

contributed some interesting information on the local distribution of this order in the

publication cited, the substance of which is reproduced in our remarks on the general

distribution of the Cactacee. The exact dates of his sojourn in Mexico we have not

ascertained, but he accompanied Galeotti on his excursions in the mountains of Real

del Monte. |

The Voyage of H.M.S. ‘Sulphur’—This expedition, accomplished during the years

1836 to 1842, was mainly for the purpose of surveying the western coast of America,

the operations extending from Peru northward to Alaska, but they were chiefly confined

to the Californian and Mexican region. A few of the Pacific Islands and New Guinea

were also visited. It was commanded by Captain Sir Edward Belcher; and the botany of

the voyage was edited by Richard Brinsley Hinds, Surgeon R.N., the botanical descrip-

tions being written byG. Bentham. Collections of dried plants were made at Panama,

the island of Taboga, the Gulf of Nicoya, Costa Rica, at Realejo in Nicaragua, in

the Gulf of Fonseca, Honduras, and in the neighbourhood of San Blas and Tepic in

the State of Jalisco, Mexico; but as the collectors nowhere penetrated far inland,

the novelties from these regions were comparatively few and of an uninteresting character.

Mr. Hinds and Dr. Sinclair, officers of the ship, and George Barclay, a gardener from

Kew, made the collections, and the plants are in the Kew Herbarium.

About this period John Parkinson, F.R.S., was British Consul-General in Mexico,

and exerted himself much in the cause of botany, both in making dried collections and

in sending living plants to this country. His dried plants are preserved at Kew.

The sixty-sixth volume of the ‘Botanical Magazine’ (1840) was dedicated to him by

Sir William J. Hooker, in recognition of his services in advancing botany and horti-

Herbarium are labelled Guatemala. We believe the first set of his collections is

at Vienna. Friedrich Ernst Leibold undertook a journey to Mexico, Cuba, and

Arkansas in 1839 *; and some of his plants were described by Reichenbach, Kunze,

and Schlechtendal f. He died at Havana in 1864, when on his way for the scientific

exploration of Yucatan.

Frederik Michael Liebmann.—One of the most active and productive botanists who

have collected in Mexico, as a reference to our Bibliography at the end will show. He

was born at Elsinore in 1813, and was educated at the College there, and afterwards

at Copenhagen. In 1840, with the help of a grant from the King of Denmark, he

undertook a journey into Mexico to make botanical and other scientific collections, a

gardener (Rathsack) being sent with him to assist him. Landing at Vera Cruz, he

started with Baron Karwinsky for the interior, and visited Colipa, Misantla, and

Xicaltepec, and then, separating from Karwinsky, went on to Papantla and Tuzutlan.

He made Mirador his headquarters during his stay in Mexico, and undertook several

expeditions from there: the first being the ascent of the peak of Orizaba with Ghies-

breght and others. The results of this expedition not only added largely to Liebmann’s

collection of plants, but also determined more exactly the limits of the different regions

of vegetation. At the end of 1841 he made an expedition by Huatusco, Cosmomatepec,

and Tomatlan to the town of Orizaba, travelling west to Aculzingo and south to

Chapulco and Tehuacan de las Granadas. About this time Rathsack was sent home:

with forty-four cases of living plants and seven of dried ones. From Tehuacan

Liebmann visited the desolate country round Tecomavaca, Tiutitlan, Cuicatlan, and

Domingilla, and from thence the oak-forests of the Cuesta de San Juan del Estado, the

valley of Oaxaca, and the ruined Palace of Mitla were visited. He also ascended the

celebrated Mount Sempoaltepec, the vegetation of which differs widely from that of

Orizaba, and made excursions into the little-known mountainous region of Chinantla

and Pelado to the silver-mines at Yavesia. He next crossed the Cordilleras to Pochutla,

whence the excessive drought drove him to Guatulco. From here he travelled along

the coast to Tehuantepec, thence returned to Oaxaca, and finally reached Mirador in

January 1843. He returned to Copenhagen in June, bringing with him a herbarium

of 40,000 plants and considerable zoological collections. He was made Professor of

Botany in 1840, and Director of the Botanic Gardens in 1849. We are largely indebted

to him for the information contained in the following pages. Alone and in conjunction

with other botanists he published many of his plants, but, dying at the comparatively

early age of forty-three, many of the natural orders were left untouched, and one of

his most important works was unfinished. This was afterwards completed by

(Ersted ; and the foregoing particulars were extracted from a biographical sketch in the

work in question. Judging from the broken set of Liebmann’s plants at Kew, it would

appear that the duplicates were distributed of such orders only as had been elaborated.

John Potts—This gentleman was manager of the mint at Chihuahua, and, in

conjunction with his brother Frederick, who lived on the borders of the State of

Sonora, he sent numerous plants, chiefly Cactaces, to Mr. F. Scheer, of Kew, between

1842 and 1850*. In 1845 Carl Heller accompanied Hartweg out, when the latter

was on his journey to California, and spent three years and a half collecting in Mexico

for the Horticultural Society of Vienna, and subsequently wrote an interesting and

instructive narrative of his travels containing many observations on the vegetation,

with a special chapter on the economic plants of Mexico {. He travelled and collected

in Yucatan, Chiapas, and Tabasco; but we have seen no part of his collections. A

portion was published by Peyritsch §.

About the same period Dr. Alwin Aschenborn collected in Mexico, and his plants

were described by Nees von Esenbach and Schauer ||, together with others collected by

Ruhland and De Berghes.

Anders Sandée Girsted.—For almost all that we know of the botany of Costa Rica

we are indebted to this botanist, who spent three years (1846-48) exploring that country

and Nicaragua, chiefly the great volcanic chain which includes the peaks of Irazu,

Barba, and El Viejo. He was afterwards appointed Professor of Botany in the

University of Copenhagen, succeeding Liebmann, whose great work on the oaks of

tropical America he completed and edited. (irsted was a prolific writer on Natural

History, but, as in the case of Liebmann, only portions of his collections have been

published and the duplicates distributed; hence the almost total blanks under many

natural orders observable in the general distribution-table in the next section but one

of this Appendix. His sketches of the vegetation of the various peaks of Costa Rica

are reproduced a few pages further on. He died in 1872, at the age of fifty-seven 4.

Julius von Warscewicz.—The principal objects of Warscewicz’s extensive travels in

tropical America were humming-birds and orchids, the latter chiefly in a living state;

yet he also made a general collection, though we have seen none of his plants. In

1846 he first went to Guatemala, and thence to Salvador, Nicaragua, Costa Rica,

Veraguas, and Panama, and on this journey made the acquaintance of Skinner and

Cirsted, from whom he received valuable aid. He discovered many new orchids,

especially of the showier class, and they are included in our Enumeration. For further

particulars we must refer the reader elsewhere *.

American Collectors during the war between the United States and Mexico in 1846 to

1848.—Major Eaton and Dr. Edwards of the United States Army collected jointly in

Nuevo Leon ; and Dr. Josiah Gregg, author of the ‘Commerce of the Prairies,’ more

extensively in the same State, in Coahuila, and southwards to Mexico city. There are

sets of these collections at Kew. But the most important of the early collections from

North-eastern Mexico is that made by Dr. A. Wislizenus in 1846 and 1847, and in

part elaborated by Dr.G. Engelmann f. Most of the novelties described belong to the

Conifer (Pinus) and the Cactacee. Only a very small set of these plants is in the

Kew Herbarium.

The Botanists and Collectors of the United States and Mexican Boundary Survey.—

Our esteemed acquaintance Dr. C. C. Parry, who has so recently, in conjunction with

Dr. Palmer, made valuable contributions to the flora of North Mexico, was the leader

of the botanical party of the Survey Commission, which commenced operations in 1849.

Dr. Parry, a native of Warwickshire, England, went to the United States when quite a

young man, and soon found congenial employment. Associated with him, or at least

taking part in the same work in connexion with the survey, were Dr. J. M. Bigelow,

Arthur Scott, George Thurber, Charles Wright {, and others. The collections made

by the last-named were by far the most extensive, and were first published separately

by Dr. Asa Gray, and afterwards incorporated by Dr. J. Torrey in his general report on

the botany of the expedition. Dr. Parry himself contributed the “ Introduction” to

Dr. Torrey’s Report, in which he deals with the physiognomies of the vegetation, the

geographical distribution of the plants, and the agricultural capacities of the various

districts. His observations on the physiognomical peculiarities of the vegetation of the

different regions are specially interesting. The bulk of the botanical collections was

made north of our boundary, though a good many incursions were made into Mexico,

and perhaps more plants were found within our limits than we have been able to

record as such, in consequence of the Kew set not being localized. For reasons set

forth elsewhere, we have adopted the Gila and the thirty-third parallel of latitude

thence to the Rio Grande as our northern boundary, mainly, however, on account of

the impossibility of deciding whether certain plants of this expedition were gathered

north or south of the present boundary between the United States and Mexico.

The Voyage of H.M.S. ‘Herald.’—Under the command of Captain Henry Kellett,

this was accomplished during the years 1845 to 1851. Dr. Berthold Seemann, a native

of Hanover *, was appointed naturalist to the expedition, on the recommendation of

Sir William Hooker, in succession to Thomas Edmonston, who was killed in Ecuador

by the accidental discharge of a rifle; and he joined the ship at Panama in

January 1847. Seemann proved an industrious collector, a careful observer, and a

fluent writer in a language that was not his own. The countries within our limits

explored by him were Panama, including Veraguas, and North-western Mexico. As

we reproduce his sketches of the general features of the vegetation of these regions in

another place, it is unnecessary to enter into further particulars here. Suffice it to

say, that he is our sole authority for Sinaloa, Durango, and other parts of North-western

Mexico visited by him. After writing the botany of this expedition, Seemann proceeded,

in 1860, on a mission of botanical exploration to the Fiji Islands, the results of which

he likewise published, though at considerable loss to himself. Subsequently he visited

Panama and Nicaragua several times in connexion with various commercial enterprises,

and although very fully occupied with business, he contrived to work a little at botany,

hoping to return to scientific research at a future period; but he fell a victim to fever

in Nicaragua in October 1871 at the age of forty-six. The first set of the Panama and

Mexican collections is at Kew, where Seemann, assisted by Sir J oseph Hooker and Mr.

A. A. Black, then Curator of the Herbarium, elaborated his ‘Botany of the Voyage of

the ‘ Herald,’” and not at the British Museum, if that is what is intended by “ study-

set” in a statement published in the ‘Journal of Botany’ +, where we are somewhat

severely admonished for not going there to consult this and other collections. But this

matter has already been explained in our Preface.

With regard to the localities cited in our Enumeration for Seemann’s plants, they are

mostly taken from the labels accompanying the specimens in the Kew Herbarium, and

unfortunately rarely quite accord with those given by Seemann himself in the Botany

of the ‘ Herald.’ As Radlkofer has pointed out {, these discrepancies are often serious

and perplexing ; and we find, in consequence, that we have omitted some species

recorded from Panama in Seemann’s book and included others which appear to have

been collected further south. |

| Ralph Tate, now Professor of Geology at Melbourne, made a small collection of

plants at Chontales, Nicaragua, at about the same date as Seemann, and perhaps in

company with him, for the numbers are often, if not always, the same in the two collec-

tions. It may also be mentioned here that Hugh Cuming, the well-known and extensive

collector of objects of natural history, collected in Taboga I. and in the Pearl Islands,

Panama, and Montijo Bay, Chiriqui river, about 1829, and there is a set of his plants

in the Kew Herbarium ; but it is impossible to distinguish in many cases which were

collected within our limits, because they are labelled ‘Panama et Colombia occiden-

talis” *. Placide Duchassaing de Fontbressin, born at Guadalupe in the West Indies f,

collected at Panama about 1850, and the novelties were described by Walpers and

Grisebach {, but we have seen none of his plants. Thomas Briggs, a son-in-law of

Hugh Cuming, visited Veraguas and Costa Rica in 1856, and there are a few plants in

the Kew Herbarium collected by him in the former country. Dr. J. F. Billberg

collected at Portobello in 1826; and P. J. Beurling published an Enumeration of the

plants). Many are described as new; but those investigated (the Melastomacee, for

example, by Dr. J. Triana) prove to belong, almost all of them, to previously described —

species.

Mateo Botteri—A Dalmatian by birth, who was originally sent to Mexico by the

Horticultural Society of London || about the year 1850; but the Society’s resources

failing, he collected on his own account and disposed of his collections through Stevens

in London. His collections of plants were very fine and extensive, and there is a full

set in the Kew Herbarium, chiefly from the neighbourhood of Orizaba, where he soon

settled, and where he died a year or two ago. A small collection of Mexican plants

from Professor Sumichrast, of Tehuantepec, presented to Kew by Mr. A. DeCandolle in

1877, bear the same numbers for the same species as Botteri’s.

Auguste Fendler began his career as a collector in New Mexico in 1846, and

subsequently collected in Venezuela, Panama, N icaragua, and Trinidad, where he died

in 18834]. His Panama collection is dated 1850, and there is a good set at Kew. The

Nicaraguan collection was a small one, made near Greytown; it is mentioned some-

where in the writings of the late Professor Grisebach, but we do not remember where.

Fendler was an excellent collector. In the Kew Herbarium is a small number of

plants labelled “Panama, Dr. Halsted, 1850.” There was, as we have been informed

by Dr. Asa Gray, a Dr. Halsted who was a surgeon in the United States Army, and

who botanized a little in North Mexico, though Dr. Gray doubted his having been in

Panama; but Mr. Salvin tells me that Dr. M. B. Halsted had charge of the foreign

hospital at Panama probably during the construction of the Railway, and that he met

Dr. Halsted, he believes, in 1859, in Guatemala, where he resided at Antigua, and where

he died shortly after. William Lobb, collector for Messrs. Veitch of Chelsea, spent

some months in the neighbourhood of Panama and Chagres in 1843, but he appears to

have dried very few plants.

E. P. Johnson.—A. small collection of plants made in Yucatan and Tabasco by the

Honourable E. P. Johnson was presented to Kew by Dr. Torrey in 1850, and merits

notice here on account of the little we know of the botany of this part.

Frederick Mueller.—An Alsatian who went to Mexico in 1853, at the cost of Mr.

Schlumberger of Mulhouse, and collected largely between Vera Cruz and Orizaba. It

is supposed that he was murdered and concealed, as he disappeared and was never

heard of afterwards. There is a good set of his plants in the Kew Herbarium.

Ludwig Hahn, who lived for nearly twenty years in Mexico as a teacher of music,

was a zealous collector of plants and animals, and sent numerous consignments of

both to Europe and especially to the Berlin Botanic Garden. Several new species of

the curious genus Wolffia (Lemnacee) are among his most remarkable discoveries. He

was attached to the French Scientific Commission with Bourgeau, and died in Mexico

in 1873. A small set of his plants is at Kew.

Carl Hoffmann and Alexander von Frantzius—These gentlemen left Europe for

Costa Ricain 1853 for the purpose of investigating the natural history and geography

of the country *, where they spent several years. Dr. Hoffmann wrote several inter-

esting papers on the vegetation &c. of Costa Rica, notably an account of the ascent

of the Volcan de Cartago and the Volcan de Barba, references to which are given in

our Bibliography. A very few of his plants are in the Kew Herbarium.

Hermann Wendland, Court Gardener at Herrenhausen, Hanover, went out to

Central America towards the end of 1856, and spent eight months in Costa Rica and

Nicaragua, chiefly occupied in collecting living plants, among which were many new

orchids f. This gentleman is one of the first recognized authorities on Palms.

in Mexico previous to 1856, in which year the late Sir William Hooker received

from him the first collection of dried plantst. From time to time further contribu-

tions were received from him, the last in 1881, through Dr. Asa Gray, from the

neighbourhood of San Luis Potosi, where he resided some time before his death, which

occurred two or three years ago. Schaffner was an excellent collector, second to

none indeed ; moreover he was a good botanist; but in the absence of the indispen-

sable literary aids he was unable to determine whether he had a novelty before him

or a previously described species, hence he frequently lost the credit due to a

discoverer, which was a source of grief and annoyance to him, particularly as some

European botanists ignored the manuscript names he appended to plants that proved

to be new. He collected very extensively in the neighbourhood of Mexico, Orizaba,

and San Luis Potosi, and most of the leading herbaria in the world have been enriched.

by his labours. Unfortunately each collection was separately numbered.

L. C. Ervendberg made a small collection around Wartenberg, near Tantoyuca, in

1858 and 1859, and this is the subject of a special article by Dr. Asa Gray *. There is

a small set at Kew.

Sutton Hayes.—A native of New York, who studied medicine, and in 1858 was

appointed Assistant-Surgeon to an expedition sent by the United States Government to

survey a route for emigrants to the Pacific States, the result of which was the construction

of a road from El Paso to Fort Yuma, which occupied two years?. During this period

Mr. Hayes made good use of the botanical knowledge he acquired during a two years’

sojourn in Paris. Symptoms of pulmonary consumption having for some time declared

themselves in his constitution, he visited the Isthmus of Panama for the benefit of his

health. Upon his arrival there his condition was so serious that it seemed improbable

that he could survive more than a few months, but the change to a warmer climate

effected such an improvement that his life was prolonged for more than three years ; but

he died in the summer of 1863. The tropical vegetation afforded Hayes a rich field of

labour and delight, and he explored it with a zeal and perseverance habitual to him,

and astonishing to those who knew the infirm state of his health. All that he did for

botany was done out of pure love for the subject, and he sustained an enthusiastic

interest in it until the last, through all the miseries attending a wasting and painful

disease. Kew, especially, benefited by his researches, almost every mail bringing

something ; and altogether he added largely to Seemann’s published enumeration of

the plants of Panama, though his additions had not been recorded before they appeared

in the present work.

About the same period Dr. Moritz Wagner travelled and collected in Panama and

Costa Rica, and he published various articles on the vegetation of these countries,

extracts from which we give elsewhere. We have seen none of his plants.

Osbert Salvin and Frederick DuCane Godman.—The editors of this work visited

Guatemala on several occasions between 1857 and 1874, and gave what time they could

spare from their zoological pursuits to botany. They paid special attention to ferns,

and made a collection of some 220 species, chiefly in the region of the Volcan de Fuego

and the Volcan de Agua. This is by far the fullest set of ferns we have seen from

Guatemala, and it contains a considerable number of novelties. Besides the ferns, there

are two separate collections of flowering-plants in the Kew Herbarium—one, consisting

of about 250 species, dated 1861, and the other, consisting of about 300 species, dated

1873-74, and ascribed to Mr. Salvin alone. These collections, although small, are

specially interesting, as they are mostly from considerable elevations on the- Volcan de

Fuego, and afford nearly all we know of the subalpine vegetation of Guatemala. We

are further indebted to Mrs. Salvin for the coloured illustrations, which were selected

from a number of admirably executed sketches painted by her in the country itself.

The collectors of the French Scientific Commission to Mexico, 1865-66.—Foremost

among these was E. Bourgeau, whose services to botany are familiar to every one

engaged in systematic work, and-with whom was associated L. Hahn, alluded to in a

preceding paragraph. Bourgeau’s Mexican collections, like all his previous ones from

other parts of the world, are very extensive, and probably more nearly exhaustive of

the districts traversed than those of any other collector in Mexico, as they contain the

most inconspicuous as well as the showy and prominent plants. He died in 1877,

while still engaged in the arrangement of his Mexican plants in the Paris Museum

of Natural History *. Kew possesses a fine set of them. Independently of the

two collectors named, several members of the military staff of the expedition made

collections of dried plants}, notably Dr. Gouin, chief of the military hospital at Vera

Cruz, a few of whose plants are at Kew. Then there were Captain Emy, Dr. Weber,

Dr. Reboud, and Mr. Thomas, attached to the marching columns, whose names appear

as the collectors of various plants described by Fournier. Thiebaut, a naval lieutenant,

collected in the vicinity of Acapulco; Virlet d’Aoust in San Luis Potosi; and Guillemin-

Tarayre, Goudet, and Franco are other names of collectors of Mexican plants received

at Kew from the Paris Herbarium. There is also a small collection at Kew made by

Bilimek, who went out as chief gardener to the unfortunate Emperor Maximilian.

Paul Lévy, a French engineer who resided in Nicaragua for some years, collected

in the neighbourhood of Segovia, Granada, &c., and wrote some interesting descriptions

of the vegetation [. He specially notes, in contrast to the flora of South Mexico, the

paucity of species, and the comparative rarity of Bromeliaceee, Cactacez, and epiphytal

orchids. The Kew set of his plants was received in 1872. |

H. Polakowsky visited Costa Rica in 1875 and collected plants, of which he pub-

lished a list, together with descriptions of those deemed new *. These we have not

seen. He also wrote on the general features of the vegetation of the country, and on

the cultivated and economic plants }.

G. Bernoulli—A Swiss gentleman who took up his residence at Mazatenango, and

made botanical collections, chiefly, so far as we have seen, of the tropical and subtropical

elements of the flora. Among other things he discovered a remarkable genus of the

Sterculiaceee, which was named after him by Professor Oliver. He also contributed

a series of letters on the natural productions &c. of Guatemala to Petermann’s

‘Geographische Mittheilungen’ during the years 1868 to 1875. Since the completion

of our Enumeration a further extensive collection of Bernoulli’s Guatemalan plants

has been received at Kew, and a few of the more important additions to the flora are

recorded in the Supplement. Bernoulli died in 1878 at San Francisco.

F. Gawmer.—A. zoologist engaged collecting materials for the zoological portion of

this work, who has also collected plants in Cozumel and other islands in the Bay of

Honduras. These collections are of considerable interest, and they are dealt with in the

Supplement.

Recent collections from North Mexico.—In the Introductory Remarks to this part, we

have given some particulars of the collections made in San Luis Potosi by Dr. C. C. Parry

and Dr. E. Palmer. More recently Dr. Palmer and Mr. C. G. Pringle have extensively

botanized the States of Chihuahua and Coahuila, and added many novelties in species

and a few genera, though nothing particularly striking, besides extending the areas of

many other genera and species. Pringle’s last collection reached Kew too late to be

incorporated in our Supplement, but partial use has been made of it in the compilation

of the tables of geographical distribution.

In concluding this bare outline of the history of botanical discovery in Mexico and

Central America, it should be mentioned that we have purposely omitted the names of

a large number of persons whose labours in this direction have been of a very limited

nature; but they appear in the Enumeration under the plants they respectively

introduced alive, or of which they contributed dried specimens.

138 APPENDIX.

OUTLINES OF THE GEOGRAPHY AND THE PROMINENT FEATURES

OF THE FLORA OF MEXICO AND CENTRAL AMERICA.

Unper this head it is proposed to give, approximately, the extent and some of the

physical conditions of the various areas into which, for convenience, the country has

been subdivided in the paragraphs of the Enumeration dealing with the distribution

of each species, together with notes on the aspects and composition of the vegetation,

extracted from the most trustworthy authorities; but no attempt will be made to deal

with meteorological phenomena beyond the barest generalizations. It may be explained

here that with the intention constantly in mind, from the commencement of this work,

to collect all definite information concerning the extent of virgin vegetation, the predo-

minence of certain genera and species, and such other particulars as would enable one

to form something approaching an accurate idea of the physiognomies of the floras of

the different latitudinal and altitudinal regions under consideration, the result is far

less satisfactory than could have been anticipated. Indeed, so few facts bearing upon

the subject exist in collectors’ notes on their plants that it has been thought better to

quote from the writings of botanical travellers rather than attempt general descriptions

or a re-casting of the materials, based upon the available data, especially as this has

already been done by Grisebach, Engler, and other authors, who have followed

Humboldt. Furthermore, the only boundaries possible in subdividing the whole

country are political ones, in consequence of the plants of many collectors not being

more particularly localized. In spite of these disadvantages, it will be apparent, we

think, that by grouping some of the southern political areas, and dividing the northern

one into two, fairly natural limits are obtained, affording data for sound deductions

respecting the diverse elements of the flora.

The whole area of land whose vegetation is here dealt with is probably less than

1,000,000 square miles, and lies between 80° and 115° west longitude (the southern

part being very narrow, the northern stretching through about eighteen degrees), and

9° and 33° north latitude on the western side, and 26° on the eastern side. An

immense coast-line, and a great elevation of the larger part of the country, subjected

to widely different climatal influences on the eastern and western sides, are the two

prominent features of the country. The southern boundary is practically the railway

from Colon to Panama, though a few plants from Portobello and Las Cruces are

included ; and the Rio Grande to El Paso, and thence across to the Gila and the head

of the Gulf of California, the northern boundary. Lower California, however, is not

included. Proceeding from north to south, the order followed throughout this work,

there are nominally seven districts or divisions, namely: North Mexico, South Mexico,

Guatemala, Salvador and Honduras, Nicaragua, Costa Rica, and Panama ; but, as more

fully explained elsewhere, there are only three distinct floral provinces within our limits,

THE FLORA OF NORTH MEXICO. 139

Norta Mexico.

It is difficult to determine, even approximately, the area of Mexico; but for the

purposes of geographical. botany this is of comparatively little importance, for it is

notorious how large a proportion of the whole flora of a country is contained within a

small space of it. North Mexico, however, is the largest of our seven divisions, having,

as here limited, its southern boundary conterminous with the southern boundaries of

Sinaloa, Durango, Zacatecas, and San Luis Potosi, extending altogether through about

eleven degrees of latitude. Mazatlan, on the western coast, is counted to North Mexico ;

and Tampico, on the eastern coast, to South Mexico. This arbitrary boundary, as the

sequel will demonstrate, coincides, as nearly as any that could be proposed from the

available data, with a decided change in the vegetation, the most marked feature of

which is the abrupt northern limit of epiphytal phanerogamic vegetation. Indeed,

excepting the littoral belt, one might say that purely tropical types do not extend into

North Mexico, although a considerable portion of it is situated within the tropics; and

this is not wholly due to elevation, but rather to climatal conditions. Much of the

country is high tableland, yet there are no lofty peaks such as characterize South

Mexico. Tula is at 4000 feet, the town of San Luis Potosi at 6170, Zacatecas at 8000,

Durango at 6700, and La Cumbre, in the State of Durango, rises to a height of 10,500

feet, the highest point, we believe, in North Mexico. Every one of the States of North

Mexico has been, more or less, botanically explored, and, although much remains to

be done, the general character of the flora is very well known. What this is may be

gathered from that which immediately follows, the geographical tables, and the para-

graphs on the general distribution of the prominent and peculiar natural orders, the

essence of which will be summed up and commented upon at the end of this essay.

The eastern States have been more thoroughly investigated than the western, yet there

is nothing published on the aspects and composition of the vegetation which merits

reproducing here. Parry and Palmer and Pringle’s recent explorations have added

very largely to the number of species, both new ones and others previously known only

from north of the Rio Grande ; but remarkably few new generic types were discovered.

Unfortunately, these gentlemen have hitherto published nothing on the aspects and

composition of the vegetation. There is, however, Dr. Parry’s sketch of the more

striking features of the vegetation of the country on the boundary-line between the

United States and Mexico*, from which we glean the following particulars. Inci-

dentally he remarks :—‘“ The observer, a little perplexed by a great variety or gradual

blending of forms, involuntarily associates particular localities with the predominating

and characteristic vegetable productions. Thus one who has ever traversed the desert

tablelands of the Upper Rio Grande will not fail to unite in his recollection of these

tracts the dull foliage of the creosote-bush (Larrea mexicana), the long thorny wands

of the Fouguieria, the palm-like Yucca, and the crimson-flowered and spine-armed

Cereus.” |

The flora of the lower maritime districts of the Rio Grande presents no feature of

special interest beyond the fact that it isa mixture of tropical and subtropical forms.

This is succeeded by rolling prairies underlaid by cretaceous rocks, abounding in trees,

including species of oak, hickory, ash, elm, walnut, cypress, &c., with an exceedingly

rich undergrowth of vines and other shrubs. The open prairies are densely covered

with luxuriant grasses anda rich and varied herbaceous flora. On the southern portion

of the Rio Grande, where there is a higher temperature, united with great aridity of

soil, a vegetation of quite a different character appears, chiefly the dense “ chaparral,”

consisting of various species of mimosa, acacia, the mesquit (Prosopis), and other

shrubs, mostly armed with hooked thorns and forming an almost impenetrable jungle.

Higher up, where the cretaceous rocks come more to the surface, new forms appear,

peculiar to this extensive region. The shrubbery is a continuous succession of the

same species, prominent among them Berberis trifoliata, Rhus microphylla, Porliera

angustifolia, Diospyros texana, Koeberlinia spinosa, Adolphia infesta, Microrhamnus

ericoides, and Celtis pallida*. Along the margins of the usually dry watercourses the

dwarf Juglans rupestris and Fallugia paradowa are constantly found. The crevices of

the rocky ledges produce various species of Laphamia and the scarlet-flowered Pent-

stemon grahami. Several members of the chiefly tropical Malpighiacee are character-

istic of this region, among them Galphimia linifolia, Aspicarpa hyssopifolia, and Janusia

gracilis. Cactaceee are numerous, especially of the genera Opuntia, Mamillaria, and

Cereus, and the curious hygrometric species of Selaginella grow on the perpendicular

faces of the limestone rocks, together with ferns of the genera Cheilanthes, Pellea,

an Notholena. <A small species of Agave with prickly leaves is very abundant and

troublesome to the traveller. The tablelands and valleys are usually covered with

““srama grass” (Bouteloua), with frequent clumps of Dasylirion. Various interesting

Nyctaginex, of the genera Acleisanthes and Selinocarpus &c., are noteworthy; and

conspicuous among annuals are several species of Mentzelia, Pectis, Hymenatherum,

the pretty Hucnide lobata, &c.; but there are so many equally abundant that it is

difficult to designate any as characteristic of the cretaceous district. The higher

alluvial tracts, forming the basin plains, produce species of more northern types,

such as Hnothera, Gaura, Riddellia, and Polygala, associated with Zinnia, Peganum

mexicanum, and Peteria scoparia. A coarse grass, which presents a uniform dead

brown colour throughout the greater part of the year, clothes the depressions in this

alluvial region; and the deep recesses and shaded valleys shelter Quercus emoryi and

* Here, as in a few other instances, the name employed by Dr. Parry has not been published, and we have

substituted what we believe to be the correct one.

Pinus edulis, with an undergrowth of Vitis incisa, Clematis pitcheri, Ungnadia speciosa,

‘&c. The constant presence of water in the larger valleys is indicated by the growth of

poplars and willows.

The vegetation of the valley of the Upper Rio Grande and that of the country imme-

diately adjoining it on either side are strikingly different. Upon the tablelands which

spread out beyond the mountain-barrier is a great variety of plants not met with in

the more fertile valley, including Fouguieria splendens, Larrea mexicana, Flourensia

cernua, Rhus microphylla, Condalia obovata, Koeberlinia spinosa, and various species

of Krameria, Ephedra, Yucca, Opuntia, Echinocactus, Mamillaria, and Cereus. Of

the numerous herbaceous and half-shrubby plants of this region Cevallia sinuata,

Greggia camporum, Eriogonum abertii, and several species of Dalea may be mentioned.

Composite are especially abundant, prominent among them Baileya multiradiata,

Bahia absinthifolia, Porophyllum scoparium, Psathyrotes scaposa, Hymenatherum

acerosum, Townsendia strigosa, Calycoseris wrightii, Stephanomeria minor, and Rafi-

nesquia neo-mexicana. The Nyctaginese are represented by Selinocarpus, Boerhaavia,

and others; and the principal grasses of the region are of the kinds known as

“bunch-grass,” and belong to the genus Bouteloua. On the margin of the tableland,

bordering the valley where it is broken by deep ravines, the sandy bluffs are clothed

with chaparral made up chiefly of mesquit (Prosopis julifiora) and thorny acacias.

Chilopsis linearis is frequent in the dry pebbly watercourses; and besides many of the

tableland plants already mentioned, there are others which are peculiar to these locali-

ties, such as Dithyrea wislizenii, Abronia mellifera, Gilia longiflora, Lepidium alys-

soides, Gaillardia pinnatifida, Palafoxia hookeriana, and Tetraclea coulteri. In the

valley of the Rio Grande dense growths of willows and poplars are frequent. Pro-

sopis pubescens often occupies large tracts, with a thick undergrowth of Baccharis

salica. In low saline places Obione canescens abounds, and Pluchea borealis on the

higher ground. A number of coarse Composite inhabit the valley, such as Zexmenia

encelioides, Coreopsis cardaminefolia, and Aster spinosus, often forming dense matted

masses. endleria rupicola, Mortonia crassifolia, Glossopetalum spinescens, Ayenia

parvifolia, Bouvardia hirtella, Tecoma stans, and Zermenia brevifolia are interesting

plants of this region. The higher mountains of the Organ range have a subalpine

vegetation and bear a scattered growth of oaks and pines, beneath which flourish a

number of herbaceous and shrubby plants similar to those on the loftier ranges

westward. . .

Passing to the Sierra Madre range, Carpochetes bigelovii, Anemone caroliniana,

Streptanthus linearifolius, Pentstemon torreyi, and P. fendleri are characteristic plants

of the lower rocky swells. Of shrubby plants various species of Ephedra are the most

conspicuous. raxinus velutinus and Juglans rupestris border the streams, and

Anemiopsis californica appears in humid situations. The mountain oaks and pines are >

timber, consisting of Pinus chihuahuana and Pseudotsuga douglasiit. The smaller

woody plants here include several Californian species, such as Cercocarpus parvifolius

and Arctostaphylos tomentosus. The vegetation of the upper valleys of San Bernardino,

San Pedro, and Santa Cruz contains a large number of endemic types associated with

an intermixture of Californian and Texan species. Proceeding to the lower Santa Cruz

valley and the desert of Tucson, a distinct botanical district is entered, where again

plants characteristic of a dry region are met with. Here Prosopis and Larrea are con-

spicuous, and Cactacee abound, and include such remarkable forms as the massive

Echinocactus wislizenti and the lofty Cereus giganteus. An Agave inhabits the crevices

of the neighbouring mountains, where also Franseria deltoidea, Encelia farinosa, and

Perityle nuda are found. After the rains the open plains are carpeted with a profusion’

of brightly-coloured evanescent annuals, among the most conspicuous of which are

Vesicaria and Eschscholtzia.

The flora of the cafions of the Rio Grande differs but little from that of the mountain

ravines already alluded to. On the abrupt walls, whether of limestone or of igneous

rock, grow Laphamia dissecta and L. bisetosa, Perityle aglossa and P. parryi, Eucnide

lobata, Cowania ericifolia, and the monotypic Emorya. In open places the charac-

teristic tableland vegetation appears. The flora of the extensive basin of Presidio del

Norte is more Mexican in character. Here grow Kallstremia grandiflora, Martynia

violacea, M. arenaria, Talinopsis frutescens, Nicolettia edwardsit, and several species

of Boerhaavia. Cereus greggit is common, and the delicious-fruited C. stramineus

flourishes in its greatest perfection.

Thus far a very much condensed epitome of Dr. Parry’s sketch.

For a picture of western and some parts of central North Mexico we cannot do

better than reproduce a portion of Seemann’s ‘Introduction to the Flora of North-

western Mexico’*, and a few additional particulars will be found in the quotations

from Hartweg’s narrative of his journeys in Mexico (see page 126). We give Seemann’s

own words.

“The district [visited by Seemann] is not defined by any political or natural limits,

but by an imaginary line extending from Acapulco north-eastward to Durango, thence

to Chihuahua, from that city to the mouth of the river Colorado, in the Gulf of Cali-

fornia, and along the western coast of Mexico to Acapulco. Generally speaking, it may

be said that a narrow strip of flat land runs along the whole coast, immediately followed

by a chain of mountains which on their eastern side join the tableland of Mexico, the -

plains of Anahuac. Such a district situated partly within the boundary of the tropics,

partly without it, and possessing lowlands, high mountains, and elevated plains, has a

great diversity of climate—is subject to great extremes of temperature. On the coast

from Acapulco to Mazatlan there are the usual tropical seasons, the wet and the dry,

the former commencing about the end of May and ending towards the end of August,

* Botany of the Voyage of H.M.S. ‘ Herald,’ pp. 262-265.

THE FLORA OF NORTH MEXICO. 143

or sometimes a little later; from Mazatlan northward to the river Colorado, a country

situated immediately without the tropics, the equinoctial seasons are less distinctly

marked, the climate partaking more of the character of that of the temperate zone, and

being besides very dry. In the mountains every altitude has its own range of tempe-

rature and moisture; the western declivity, however, possessing generally a higher

temperature and a greater degree of moisture than the eastern. On the higher summits

the rivulets are frozen during the cold season, and snow often falls.

“ ‘The climate of the tableland of Durango and Chihuahua is like that of the greatest

portion of the elevated plains of Mexico, dry, differing in that respect essentially

from that of the higher regions of the Colombian, Ecuadorian, and Peruvian Andes,

where moisture is abundant, and brooks, rivers, lagoons, and lakes promote a more

luxuriant vegetation than is to be met with in Mexico at similar elevations. The

extremes of heat and cold are unknown. Towards the end of February the night-frosts

cease ; spring commences, poplars and willows begin to get green, peaches and apricots

put forth their blossoms, but the temperature alone, though fast increasing during

April and May, is not sufficient to awaken nature altogether. The fields remain dry,

until towards the latter end of May, or in the beginning of June, the vivifying rains

set in; in a few days every herb, every shrub, and tree has started into life, and the

vegetation develops itself with great rapidity: the season answering to the North-

European spring has commenced. LEarly in September the rains cease ; in October the

night-frosts (which last until February) recommence, except which there are few

indications of winter; snow seldom falls, and never remains long on the ground. The

great aridity of the climate is best illustrated by the fact that, although the rainy

season only terminates early in September, there is very little water to be met with in

any part of the plains during the winter months (October until February). The

periodical streams seem to disappear at the moment the rains themselves cease, and

the perpetual springs, streams, and small rivers are so few in number that the traveller

has very often to search for hours ere he is able to meet with water; fortunately the

Mexican flora mostly has furnished a guide to places where there is always a good

supply by planting on the banks of the running streams Sabino trees (Taxodium

distichum), to inform the weary traveller, when he descries their high waving tops,

that the object of his search is close at hand.

‘‘The immediate neighbourhood of the coast is generally lined with a dull maritime

vegetation, the Mangrove tree being very frequent, and appearing from Acapulco to a

little to the north of Mazatlan (lat. 24° 38’ N.), where, together with the Cocoa-nut

Palm and many other forms common all along the western shores of America, from

Guayaquil northwards, it reaches its extreme northern limit. Advancing a short

distance inland, the aspect of the vegetation improves, trees of Crescentia alata, Hama-

toxylon campechianum, Cordia gerascanthus, Ipomea arborescens, Crateva tapia,

evergreen Figs, and feathery Mimose, shrubs of Bizra orellana, Malvaviscus arboreus,

144 APPENDIX.

different species of Hibiscus, Triumfetta, and Poinsettia pulcherrima, a great variety of

creeping and winding plants such as Clematis dioica, numerous Convolvulacex, and the

splendid Antigonon leptopus, which, between Mazatlan and San Sebastian, covers almost

every bush with its pink blossoms, are to be met with.

“ On ascending the mountains we meet, about 1500 feet above the sea-level, the first

evergreen Oaks, which soon increase in number of species as well as in that of indi-

viduals, and are, at the height of about 3000 feet, joined by various Conifere and a

rich mountain vegetation. It is about at this height that the traveller realizes all the

ideal notions he may have conceived of fine localities and beautiful vegetation. Santa

Lucia, situated on the road from Mazatlan to Durango, may serve as an appropriate

illustration. Situated about 4000 feet above the sea, enjoying throughout the year a

temperate climate, it lies in a romantic valley encircled by wooded mountains which

admit a view of the Pacific Ocean. The houses of the Indians, scattered over an

undulated surface, are surrounded by a vegetation in which the graceful forms of the

tropics are harmoniously blended with those of the temperate zone. Mimosee stand in

company with Oaks and Firs, hardy Umbellifere and Composite with Cupheas,

Lobelias, and Lophospermums ; nearly every hedge is overgrown by a splendid Ipomea,

the azure blossoms of which are from four to five inches across, and set so close together

that hardly a leaf is to be seen, and the whole plant resembles a blue sheet, whence it

derives its vernacular name, ‘Manto de la Virgen’ (Cloak of the Holy Virgin).

“At a greater elevation the tropical forms disappear more and more before those

usually termed EKuropean—Amentacee, Conifers, Ericacee, Gentianee, Rosacee, &c.

Ferns, among them two familiar acquaintances from Europe, Pteris aquilina and

Osmunda regalis, become more abundant, if not in species at least in individuals,

especially in the ravines (barrancas), localities which in these as well as in other

parts of Mexico are amongst the richest the botanist can explore. Near the Rancho

of Guadalupe the author found in one of them, among many other rare plants,

a Lonicera, a Hydrangea, and Chamecyparis thurifera, a noble tree, attaining —

the height of 100 to 150 feet, and always growing, like the Taxodium distichum, by

running streams.

“The tableland is in most parts very thinly wooded. For miles and miles you

behold nothing save shrubby Opuntias, intermingled with Visachas (Acacia farnesiana,

Willd.), or groups of Taxate (Juniperus tetragona, Schlecht.) ; indeed, the vicinity of

Durango can only boast of about seven species of indigenous trees, namely: a Willow,

the Acacia just named, a Prosopis, Crataegus mexicana, Taxodium distichum, Casimiroa

edulis, and a Yucca. These, together with a few shrubby Acanthacee, Composite,

Scrophulariner, and Cactee, and the everywhere prevailing Agaves, are the chief

representatives of the flora one meets with during the winter. Of Cactee the immediate

neighbourhood offers three Opuntia, two Echinocacti, and a Mamillaria.”

THE FLORA OF SOUTH MEXICO. 145

South MExIco.

For reasons already explained in the sketch of North-Mexican vegetation, we can give

no definite particulars of the area of South Mexico, except its geographical limits. It

lies between about 16° and 23° of latitude, and 87° and 107° of longitude, yet in its

widest part, about 20° lat., it extends through only eight degrees of longitude. It is

reckoned that three fifths of the whole of Mexico consists of an elevated tableland, 6000

to 8000 feet above the level of the sea, from which rise numerous lofty ridges and

peaks. The principal peaks or volcanoes are:—Colima, Jalisco, 12,750 feet*; Cofre

de Perote, Vera Cruz, 13,420 feet; Orizaba, Vera Cruz, 17,879 feet; Popocatepetl,

Mexico, 17,784 feet; Sempoaltepec, Oaxaca, 13,100 feet; and San Cristobal, Chiapas,

6500 feet. This great mountain-chain is nearly severed in the Isthmus of Tehuantepec.

South Mexico is by far the best explored of our botanical provinces, and parts of

it at least, especially the region of Orizaba, vie in richness and variety of vegetation

with the most favoured districts of Colombia. From the great differences in elevation

of the various States, and the diverse climatal conditions in operation, it is obvious that

only by a series of pictures could an adequate idea of the vegetation of the whole country

be conveyed. ‘Thus Yucatan, from its lowness, has an almost wholly tropical, though

very scanty, vegetation; and from its proximity to the West Indies there is an inter-

mixture of characteristic West-[ndian types of vegetation; whilst other States

exhibit every type of vegetation from tropical to alpine. Numerous sketches of the

vegetation of more or less restricted areas of South Mexico are scattered through

a variety of publications in various languages, references to the majority of which are

given in the Bibliography at the end of this work; but few of them are sufficiently

exact, or complete enough, to be used here. The best and most comprehensive is by

Richard and Galeotti, the substance of which is given further on, under the head of

“‘ Altitudinal Distribution of Orchids.”

Liebmann’s description of the successive zones of vegetation from the coast at Vera

Cruz to the summit of the peak of Orizaba f is a most interesting and instructive sketch,

and we here give an abridged and condensed translation of it.

The most interesting mountain in North America is the volcano of Orizaba. It.

is only thirty leagues from the coast, from which the ground rises immediately though

imperceptibly to its foot, giving it an appearance of even greater height than it.

possesses. Its cone, crowned with eternal snow, is 17,000 feet high, and can be seen

from a distance of 100 miles; it extends north and south in two huge flanks, each of

which averages about 9000 feet in height. On journeying from Vera Cruz westward

sparse, low, shrubby vegetation, entwined with numerous creepers, is encountered on

the hills which lie close to the sea-coast. The grassy plains at Santa Fé, at an altitude

of 200 feet, become covered, a mile further on, at Boca del Potrero, with a dense wood,

which extends as far as Tolome without any rising of the ground. This wood is com-

posed chiefly of Mimosa, Acacia, Bombax, Pachira, Citrus, Acrocomia, and Combretum.

The ground, which has hitherto been sandy or marshy, now changes its character, and is

succeeded by numerous hills formed of horizontal strata of a hardened marl mixed with

sand ; over these hills are scattered great blocks of rounded black porphyritic rocks

from the distant crater of Orizaba. On this fruitful but almost uncultivated land maize

produces 400-fold, and the sugar-cane grows as tall as the best kind in Havana. Thick

woods of Acrocomia aculeata and the Palma real (Oreodowa) &c. cover the country

here.

From Paso de Ovejas to Hacienda Mirador, a distance of thirteen leagues, the ground

rises imperceptibly in a monotonous stony slope or grass savana, on which grow low

thorny species of Mimosa, groups of the white Convolvulus arboreus, yellow Bignonia,

and Cochlospermum. Atan altitude of 3000 feet six or seven species of oak are found, and

six species of Chamedorea, including climbers as well as standards. Here, ina temperature

of 70°, and favoured by the long rainy season of eight or nine months’ duration, the

richest vegetation of Mexico exists, and orchids reach their maximum with some two

hundred species, some terrestrial, but mostly epiphytal. The basaltic porphyry, which

extends from this altitude (3000 feet) to the very summit of the volcano, is covered by

a strata of hard red clay containing iron, which extends up to above 11,000 feet. From

Mirador the country becomes more mountainous ; great ridges run north and south,

intersected by deep ravines produced by earthquakes, extending west and east, and

forming natural watercourses. At San Antonio, Huatusco, and San Bartolomé oaks

reach their highest development, not only in the number of species (no less than twenty

species being found), but also in their size, which is greater than anywhere else in

America ; and one group with acorns 8 to 9 inches in circumference is limited to this

district. The highest limit of coffee and cotton cultivation is reached at an altitude

of between 4000 and 5000 feet; while the sugar-cane, though losing much of its

strength and sweetness, is cultivated up to 5500 feet. Associated with the oaks here are.

Laurinee, Myrtacee, Anacardiacex, Malpighiacex, and Anonacee, with an undergrowth

of Melastomacee, tree-ferns, Citrosma, Mimosa, Acacia, Yucca, reed-like bamboos,

Triumfetta, Jatropha, Croton, Magnolia, Composite, Symplocos, the red Aisculus,

Aralia, &c. Liquidambar styraciflua has a very distinctly defined vertical area, lying

between 3500 and 5500 feet; and Platanus mexicanus is still more limited, only growing

by running water at 4500 to 5500 feet. |

The town of San Juan Coscomatepec, at about 6000 feet, lies at the foot of the

Cordilleras; and a league and a half further, at the town of Santa Maria Alpatlahua,

the ascent of the volcano begins. This fruitful region has, for 300 years, uninterrupt-
