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 Fig. 1, skies with part of axis; 2, lower glume; 3, upper ee : me ated (florets) ; 5, palea and flower of a young lov ea ate oret ; Sgqitiet sore flower, seen from the back ; 7 and 8, grains.

Pierre had three species in manuscript under the generic name of Megabaria, M. Trillesii, M. obovatum and M. Klaineanum.

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.

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 7 recently proposed for Bureau’s genus the name Distictella (Post et Kuntze, Lexicon, p. 182).

Henry, 311, 1052. 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 2 suggested it ares twenty years ago. Its relationship to Rehmannia, 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 axils of the specimen, bea the same minute bracts and in the axils profusion. It may detaching themselves at the base of the stalk. The other specimen referred to (one of the set numbered pe is evidently a young plant ears two flagelliform axes, one terminal, the other axillary, wit a few distant seve bracts and. very few bodies of the nature described above.—O.

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 Fig. 1, pair of flowers; 2, corolla laid open; 3, stamens; 4, style; 5, longi- tudinal section of receptac acle ; 6, cross-section of same with one cell empty ; ao of another receptacle, with a row of ovules in the third cell.

CentRaAL Tiset: Gooring Valley, ta m., Littledale. SIKKIM: Naku Chu Valley, 4800 m., Smith & Cav 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.

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.

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.

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.

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.

Bentham has placed Cunuria in the Jatropheae, and Pierre in his MSS. notes in Herb. Paris has suggested the same position for Klaineanthus. Miiller, on the other hand, placed Cunuria near Cheilosa, which Bentham includes in the Acalypheae.

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 .

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.

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.

Common at altitudes from 600-2100 m. throughout the Ghikaalie desert, Mexico. 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.
