I know of no near ally of this fine species which is amongst the minute-

flowered species of the genus, remarkable for its tall, robust habit, for

the profusion of very small flowers umbellately arranged on the tips

of the many subcorymbosely disposed peduncles, and for the whorled

bracts. e pedicels are rarely racemosely arranged on the peduncles,

and not sstndaaeniy one of the pedicels of the umbel bears a bracteate

2

umbellule. I have seen no mature capsules, but I cannot doubt that

they are pentagonous, as are the ovary and immature fruit.

Professor Urban informs me that the seeds of this plant were sent

to the Royal Botanic Gardens of Dahlem from that of Calcutta, together

with those of I. Langeana, in 1901, and that they had been collected

in Kumaon. ey were sown in the Royal Botanic Gardens at Dahlem,

and flowered in the same year.—J. D. Hooker.

ere can be no doubt as to the affinity of this remarkable grass ;

the diioulty lies rather with its Lpraeree status, whether it should

be treated as a distinct genus, and if not, to which of the two genera

named in the differential diagnosis, Vv1z. 1 pie and Coelachne, it should

be referred. Coelachne was placed by Bentham with the Aveneae in

net mee and Hooker’s Genera Plantarum, and Hackel treated it in the

ame way in his classification of the grasses in Engler and Prantl’s

Rutatiche cn ee The oe however (Journ. Linn

reducing Oe to Lsachne ; but to be consistent they would have to

one, or even more than one, direction ‘ pass’ into other genera. If,

on this ground, /sachne and Coelachne are allowed to stand as distinct

to produce two fertile florets, ae correlated with it the tendency

sears disarticulation of the rhachis between them and to a lesser

degree below them, instead of shedding the whole spikelet as is the

case in the more typical Paniceae where each —— develops only one

grain, achne, the in floret is always hermaphrodite and has

the typical Pacanatnete The tae is Bree

such forms might purely batiieaglls be claimed for Panicum. It

pts shows frequently, even if hermaphrodite, that approach in shape

and structure of its valves to the shvabieed glumes which is tei charac-

teristic of the reduced lower floret of Panicum. In Heteranthoecia

3

and Coelachne the lower floret is always hermaphrodite and fertile ;

buttits valve en repeats to a considerable degree the features of the

preceding glu On the other hand the upper floret is more

aiecialiaed and éppinally female. It is in both genera terminal in the

sense in which it is so i Panicum, and its close position to the lower

floret, owing ie the reduction the int ervening internode as well as the

grain are distinctly paatinisid > In Coclachne, however, the internode

between the florets is lengthened, and the upper floret, which is carried

away from the lower to a degree quite unusual in Paniceae, ' is also less

‘ id.’ eculiar structure of the Seperi with its flattened,

ungent t branches and secund , biseriate, sessile spikelets has no parallel

in Isachne or Coelachne ; but consi ering the wide range of modifications

we meet with in the inflorescences of Panicum and Paspalum, not muc

stress can be laid upon it as a generic character, although it is certainly

Africa (7 amr oi age ern (1 species). There are, however,

3 species now kno om Tropical Africa, B. huillensis, 0. Hofim

species here described.

Mr. EK. Battiscombe, assistant to Mr. D. E. Hutchins of the British

East African Forestry Department, has sent to Kew two photographs

of the trees, which give an excellent idea of their habit, and a third

showing the ag neo of the bark. The trees appear to grow in

clumps in the annah forests near Nairobi, and according to Mr.

Battiscombe are on also in the forests nearer the coast. They attain

a height of 90-100 ft., at an elevation of 5( ft. ; the crown is thin

Owing to the lamented death of M. Pierre the two species here

described have not been hitherto published under their correct genus.

Pierre had three species in manuscript under the generic name of

Megabaria, M. Trillesii, M. obovatum and M. Klaineanum.

The first of these was published by De Wildeman, igs ee

without a description (Etud. Fl. Bas- et Moy.-Cong. vol. ii. p. 284).

It has, how baa been described along with another iacina re Toxuds

in the Kew 0, p.57. MM. Trillesit therefore will have to be re-

garded as my type of the genus Megabaria. The two other species are

not congeneric with M. Trillesii, but Pierre appears to have intended

them to be the types of his new genus, for he had excellent detailed

drawings distributed with these specimens, but not with those of M.

Trillesi1. He seems to have at first regarded this last species as belong-

ing to Thecacoris, for on Trilles’s label in the Kew Herbarium.there is

written in Pierre’s handwriting ‘ Thecacoris ? Trillesii, Pierre.’ From

Thecacoris, however, M. Trillesii is at once distinguished by its panicu-

> en ome ie of co a bracts, and by the absence of petals in the male

flowers.—J. HurcHtnson

vol. viii. pars 2, p

On the strength of a superficial resemblance which had been noticed

previously by A. P. de Candolle (Prodr. vol. ix. p. 158), Miers included

A. crassa and A. trichoclada in his new genus Cremastus. Cremastus

has now been restricted of ny and ch in aye 214) to C. a

airs.

The indumentum, calyx, corolla an < of A. crassa are similar to

those of Distictis, Bur., and this led Birean and Schumann, who had

not seen the capsule, to pore the species to that genus. Apart from

the very different capsule, Distictis, Bur., may be distinguished by the

thickened bases of the filaments and the silanieetiade ovules. As has

been pointed out by Schumann (l.c. 175), Distictis, as define

which is also now definitely referred to Gesneraceae, has been so ably

anomaly described by Hemsley requires a brief explanati ion. In

Annals of Botany, |.c., he says of the inflorescences : * racemi simplices

vel interdum ramosi saepe valde elongati et gracillimi, supra medium

prolifer! corporibus minutis fasciculatis peice These anomalous

racemes occur in Henry’s eee no. 311, and in one of the specimens

numbered 1052. In no. 311 the ane inflorescence is produced

beyond the flowers into a flagelliform slender axis about 30 cm. lon

bearing in the axils of small subulate bracts and bracteoles clusters of

—in the dry state—blackish bodies which consist of a short stalk and

2-4 fleshy subulate organs probably homologous to the first 2, 3 or 4

sepals. If this conception of the nature of those organs be correct, the

odies would represent rudimentary flowers. What their function is

or a they are aid teratological is not known. Similar fla ase

form axes, | cm. peden and extremely slender, also rise from the leaf

The affinity of Kolkwitzia lies clearly with Abelia, from which it

differs in the paired and ultimately coalescent flowers, in the production

of the receptacle into a slender and rather long stalklike tube, the not

enlarged, although eet sepals, and the presence of numerous

ovules in all the cells of the ovary or at least in two of them, although

only one in each fruit develops into a seed. The corky ribs of the .

fruits with their awl- or horn-like points are, as Mr. Hemsley has pointed

out, the indurated bracts which in the course of maturation are carried

up on the growing i aan whilst the decurrent bases go to build

The salient characteristic of Gooringia is the presence of only two

sever py which are opposite the inner sepals. A third stamen, opposite

one of the outer sepals, was found in one flower, and a sta minode, more

or les reduced, sometimes occurs in the same position (see figs. 4-5).

Reduction to such an extent in the androecium is rare in the Alsineae.

Buffonia tenuifolia, L., however, is vaeg aes Boissier (Fl. Or. vol. i.

665) to have three or more rarely tw mens ; Cerdia, a Mexican

genus of Polycarpeae, has only a oa pene ; Pollichia, an African

enus of Paronychieae, has o 0; Dich hus, of tribe

—— has two or three ; ty fa eccies may have one, two, five

** The disk of Gooringia consists of four lobes, opposite the sepals ; the

lobes opposite the inner ah are bilobed, and those o eas the outer

they are generally bilobed.

In the previous seat tap ss of G. Litiledalei the flowers are stated to

be apetalous. Petals were found, however, in all the flowers examined

during the antarsiok of the present fizure and description. They are

usually entire, occasionally emarginate or bilobed.

Apart from ‘the reduction in the number of stam ens, Te differs

from Arenaria in the tetramerous flowers ; from Bu uffoni va in the four-

valved capsule ; and from Moehringia in the estrophiolate seeds.

is plant was originally described as a Bleekrodia ; but quite epee!

(Bull. Ec. de Indochine, vol. xi. p. 175) its authors suggested t

it might be a distinct genus, mainly on account of the perianth aot

becoming fleshy in the fruiting —— as stated by Blume for Bleekrodia.

They suspected, however, an error in Blume’s description owing to his

having mistaken the pericarp ios the perianth. There are no fruiting

specimens of Bleekrodia at Kew, but Boerlage (Handleid. Fl. Nederland.

Ind. vol. iii. part i. p. — og in his oe of the fruit is quite explicit

on that point. He says: ‘ Frui osed in the thin perianth, dru-

paceous ; outer layer "licen ‘of the fruitwall very thick below,

2-lobed, thin on the top ; inner layer (binnenlaag) papery.’ This reads

very like the description of the fruit of the plant in aac except as

far as the perianth is concerned. Acco to age this in the

flower is tubular, contracted above and provided with 4 short teeth, and

nothing is said of its breaking up into 4 bractlike parts such as we find

in the fruiting stage of the Teo-nong. It is in fact just this structure of

There can be iittle doubt as to the affinity of this genus with the

Australian genus Astrebla. This will be at once clear if we imagine the

lateral lobes of the floral glumes of or as waco adnate to the

hardened middle lobe up to the base of the awn and both glumes so

reduced as, in certain species of Astrebla, is the case with the lower.

The nervation of the floral glumes follows the e type as that o

Astrebla, whilst the peculiar reduction of the hex fice: the structure

of the awn oa the toughness of the rhachilla are characters common

to both genera. The species of Astrebla, which form the basis of the

genus, were idkadlg baal oy belonging to Danthonia (Lindley, in

Mitch. Journ. Trop. Austr. 365 and Three Exped. East Austr. 11. 26)

and Darker himself (in Flor yrenes vii. 602) admitted that ‘it is

certainly nearly allied to Danthonia, but the central lobe and the un-

twisted awn induced him to place it (Fl. Austr. lc.) nex o-

phorum and the inflorescence to refer it later on to Chlorideae (Journ

06 n. Plant. ii. 1170). As to the inflorescence, it

may be pointed out that the secund, spiciform raceme characteristic of

so many Chlorideae also occurs in Danthonia disticha, Nees, whilst the

valves and the awns approach—the latter apart from its not being

spirally twisted—much closer to those of Danthonia than of Pappo-

horum or Enneapogon. I may add — = i florets of Astrebla

The

triticoides, F. v. Muell., are osha ah anthers are very

small and entangled in the more or Tess cui up ee ea not unlike

those of phir: brakes yi fia The anthers of the lower

florets, however, are normal.—O,. StTarr

There are many excellent specimens of this species in the St. Peters-

burg Herbarium, varying greatly in size, pede very little in habit and

foliage. The small flowers of herbarium specimens are troublesome

to analyse, owing to the flaccidity, pine ae condition, contortion and

2

cohesion of the organs. The wings are characteristic in that the nye

auricles are placed horizontally on a dorsal lobule of the wing. I

met this arrangement in any other species of the genus.—

TropicaL Arrica. Abyssinia: a January 1909, Dr. Drake-

Brockman, 187, 188, 189, 190, 191,

The plant has been identified from Lindau’s description of the type

specimens collected by Riva at Dschacorsa, Somaliland. Although

the striking morphological features are in agreement, there are several

slight discrepancies. For instance, the style of the type is stated to be

27 mm. long, that of the Abyssinian plant is 45 mm. long. Again, the

calyx-segments are described by Lindau as being 30 x 7 mm., those of

Drake-Brockman’s plant average 21 xX mm.

The small glands (which in the dried specimens appear as hya-

line scales) found on all the parts with the exception of the old

wood are in agreement with the general xerophytic habit of the

plant. The calyx-segments (as in other species of the genus)

are connected by a delicate membrane. When dried calyces are

boiled the segments immediately separate to the very base. The

reduction of the anticous petal to a thickened spur is remarkable.

The filaments are united in a peculiar manner. One anticous and

one lateral filament unite to form a comparatively broad membrane

the second lateral one to form a second membrane unilaterally

adnate to the corolla tube. This arrangement gives the appearance

of a staminal tube split down one side and attached on the opposite

side for its whole length to the corolla tube. The disc is represented by

a narrow ring of tissue (hardly distinguishable from the receptacle and

pe 15 mm. high, as crete by Lindau for the Somaliland specimens),

m the inside of which on the posticous side arises a slender spur

cae half the length of ea ovary. The backs of the anthers and the

ovary are densely covered with glandular scales—W. B. TurRILL

for Klaineanthus. Miiller, on the other hand, placed Cunuria near

Cheilosa, which Bentham includes in the Acalypheae. Neither position

The genus Spondianthus was first dealt with by Pierre, but nothing

relating to it was published by him. Specimens were distributed under

the name of Megabaria Trillesu, Pierre, and assigned to the tribe

Phyllantheae of Epo aceae. Later Pierre’s name was taken up by

De Wildeman (l.c.), who, however, did not publish a description.

The writer, whilst estas with the genus for the Flora of Tropical

Africa, published a Latin diagnosis in the Kew Bulletin (.c.) and included

a second closely allied species from Uganda (M. ugandensis). He was

at that time unaware of Spondianthus, Hasict. containing two species,

which had been placed by its author in Anacardiaceae. Subsequently

(in Notizblatt Kénigl. Bot. Gart. Berlin, 1911, No. 48, p. 240) Engler

transferred Spondianthus to Euphorbiaceae, at the same ‘ie admitting

its identity with specimens distributed by Pierre as Megabaria Trillesii

represents quite a distinct genus, and was described and figured as such

y the writer at tab. 2929 of this work under the name Protomegabaria.

i Spondianthus in a restricted sense (i.e..S. Preussti and S. ugandensis)

the leaves are subverticillate, the inflorescence paniculate, there are

petals in the male flowers, and the capsule is loculicidal ; in Protomega-

The position of this anomalous genus is apparently in the sub-

tribe Vanilleae, as defined by Bentham, but it differs from all

its allies in the long conduplicate ee and ae most of

them in the lateral inflorescence. s character however,

seen in Sertifera, Lindl., and in some ries of Vanilla, Swartz.

In floral structure it bears a general resemblance to the latter genus,

the base of the lip being adnate to the front of the column

a considerable distance, though the side lobes are not adnate to

its margin so as to form a tube. The pollinia are in bad condition,

but so far as can be seen they pete Vanilla, as do the anther,

stigma and rostellum. The habit, however, is totally different. We

produced after the lower leaves have perished. The earliest evidence

of the existence of such a plant is found in a few flowers on a Herbarium

sheet at Kew which were originally preserved in spirit, also a sketch of

the column. This plant is said to have been sent from Trinidad by

Prestoe, and flowered at Kew in September 1870. A sketch is said to

have been sent to Reichenbach, who returned the name Chloidia flava,

Reichb. f., from which, however, it is quite distinct. The plant 2

to have died and no specimen was preserved. Specimens of the s

thing were afterwards sent from British Guiana by Jenman and ee

species was described under the name of Jenmania elata, Rolfe. Dr.

Zahlbriichner then pointed out that the generic name had previously

been given to a lichen, and changed the name to Rolfea elata. It has

since been collected in Guiana by Im Thurn and in Trinidad by Lunt,

the specimen of the former bearing a seed-pod much resembling that

of Vanilla palmarum, Lindl. Lunt describes the lip as yellow with

i ey agethnwe throat, and the other parts of the flower as bright red.—

Roxb., has been suggested as an ally, but this differs greatly in the

The most interesting feature regarding Gar denia sokotensis is its close

affinity with G. succosa, Baker, a species so far known only to occur in

Madagascar. ‘ shows no distinct relationship with any other African

species known

The genera Randa and Gardenia, as at present defined, are separated

merely by the position of the placentas ; in the former the ovary is two-

2

or more-celled with axile placentas, whilst in the latter the eee

tion is parietal. In many species of Gardenia, however, we have found

that the placentas towards the base of the ovary are frequently coherent,

and a transverse section at this point would be the same as one across

the ovary of a typical species of Randia. It has long been our opinion

that these two genera should be entirely recast, the distinguishing

characters being taken from the shape of the corolla ‘tube and the nature

of the stipules. These characters, associated with the number of the

ovarian cells and the position of the placentas, would probably result

in the segregation of a few (4-6) smaller and fairly distinct genera.

The proper position of the Mrs here figured, in spite of the axile

placentation, seems to be in the section Rothmannia, which was described

as a genus by Thunberg.—J. Hurcuinson.

The receipt of some good specimens of this handsome me distinct

and presented by Mr. A. K. Bulley, affords an opportunity for figuring

it and at the same time enables us to amplify in some respects the

is now possible to state with certainty that the corolla is naked inside,

not fimbriate in the throat.

alone in the section Stylophora created for it by Mr. Clarke, appears to

This is the first species recorded from Africa. The Kew Herbarium

contains fragments of a second that was collected near the Cunene

River in Angola by Sir Harry Johnston, but the material is scarcely

sufficient for descriptive purposes.—N. E. Brown.

L AFRICA. ger Nigeria: Yola Province; planted in

cage Dalsiel (coll. 1909), 1

Boswellia odorata is ae in the native towns of Yola Province,

Northern Nigeria, where it was collected together with another very

fine new species, B. bingy Hutchinson, by Dr. J. M. Dalziel, of the

African Medical Service. The fragrant resin, which is a product of the

plant, is burnt by the natives to fumigate their clothing, and it is also

used medicinally. The Hausa name is ‘ Hanu’; the Fufulde name is

* Andakehi.

The nearest ally of this species is B. papyrifera, Hochst., which occurs

in Abyssinia and the Eastern Sudan, and Chevalier has sathered what

appears to be the same in the Central Chari region.—J. HUTCHINSON.

For a comprehensive account of the Mexican rubber plant here

figured, the shies oe is referred to Prof. F. E. Lloyd’s book on the subject,

entitled ‘Guayule, which was published in 1911 by the Carnegie

Institute of Woktaglon

he guayule (Parthenium argentatum) was discovered in 1852 near

Escondido Creek, Texas, by Dr. J. M. Bigelow, of the Mexican Boundary

Survey. It occurs on the high plateaux from the south-western part

of Texas throughout the Chihuahuan desert of Mexico as far south as

Hidalgo. The plant is common on the foot-hills and slopes, especially

those favoured by a southern aspect and where the soil is highly ca cal-

careous. According to Lloyd, the country through ey it is distri-

buted embraces an area of about 130,000 square miles, and he estimates

that about 10 per cent. of this area carries guayule shrub.

Before its value as a rubber-yielding plant became known, the shrub

was used extensively as fuel by Mexican brick-makers, and thus thou-

sands of acres were depleted. The total original quantity of the plant

sumption in 1911 the natural supply would be exhausted in six to eight

years. The rubber already exists as such in the cells of the plant, and

its extraction cannot therefore be accomplished by bleeding, as in the

case of latex-bearing plants, but by crushing with machinery and subse-

quent separation by various methods. The quality of the rubber is

only moderate.

Reproduction is carried out by means of suckers and by seeds. The

manner in which the flower-heads of Parthenium argentatum become

dismembered is very remarkable. In each head there are two series

of sees bracts, five in each series, five female ray-flowers, and

numerous disk-flowers (essentially male) in the middle, each of the last

ps: enveloped by a sie of the SS When ripe the flowers

he inner series of bracts fa y from the outer series of bracts,

which-i is persistent on the peduaie a each ray-flower and ok, or

the adjacent disk-flowers and their paleae, and their subtendin

volucral bracts become attached to one another by concrescence a

3

fall away as a whole (see fig. 5). The receptacular paleae surrounding

the male or disk flowers are attached at their base to a cartilaginous

strand or rib on each side of the achene, and by using a little force in

dissection these strands separate upwards from the base of the achene

and from them hang the male flowers. The whole arrangement suggests

an adaptation for distribution by wind, as the male flowers and

their paleae at length become dry and shrivelled and would serve

as wings; the pappus, on account of its eee would appear

to be of little service in this respect.—J. Hurcnin
