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

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.

I. microtheca is an ally of I. Goughii, Wight, from which it differs in its age flowers and in the deeply bifid distal lobe of the wings. Owing to the minuteness, contraction and distortion of the floral iste I found it difficult to lay them out for the description, which may want revision.—J. D. Hook

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 So : sb aces

connecting or converging oe will perhaps find no difficulty in reducing Oe to Lsachne ; but to be consistent they would have to merge Isachne in Panicum, ite Panicu lum

h 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 useful oyponows & No Coelachne is so far known from the African continent, nor do a ay = the meet species = Isachne approach

The species here figured is the most northern outlier of this small and interesting genus which was until recently known only from South

2

Africa (7 amr oi age ern (1 species). There are, however, 3 species now kno om Tropical Africa, B. huillensis, 0. Hofim from Angola, B. cae. S. Moore, from the Matoppo Hills, and the 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-

um., a abhi of Minas npn and a Pry, of which neither fully

genus as extended by Bureau aud K. Schumann in Mart. Fl. Bras. 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

The systematic position of this plant as the representative of a distinct genus of the Gesneraceae was pointed out independently and almost simultaneously by Solereder and Hemsley, the latter having

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 axils of the specimen, bea the same minute bracts and in the axils

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 up the tibs.—O, Strap

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.

—— 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. stands in the same relation to Puen as raise does to Alsine.

ToNnKIN: on more or less calcareous soil in most of the provinces along the Chinese Frontier, and in the provinces Ninh-Binh and Hoa- Binh, south of the Red River; known in Tonkinese as * Teo-nong.’

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 the a flower which makes it impossible to refer the Teo- war

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

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

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- baria the leaves are scattered, the inflorescence racemose, there are no petals, and the capsule is ee .

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.—

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 species, which were included in the collection made by Pére T. Monbeig

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 original description, which was based on unsatisfactory material. It is now possible to state with certainty that the corolla is naked inside, not fimbriate in the throat.

The only species nearly allied to G. stylophora, which still stands alone in the section Stylophora created for it by Mr. Clarke, appears to be G. venosa, Hemsl., from Szechuen, epae for which Mr. Hemsley established the section Megacodon. They are, however, easily distin- guishable, the latter ee a 9 oe pea jae and a broadly cam- panulate corolla.a—s. A
