The genus Lcheveria was proposed by Decandolle in 1828 for those species from America which earlier authors had referred to Cotyledon, originally founded by Linnaeus on African and Mediterranean plants. The new genus differed from Cotyledon mainly in having the petals connate only at the base and the stamens shorter than the petals. In 1865 Bentham and Hooker declined to accept these differential characters as adequate. In their view the only character by which Echeverta could be distinguished from Cotyledon is to be found in the — pentagonal corolla. But floristic convenience at times finds monographic canons unduly severe, and its dictates have induced Dr. Rose to reconsider the verdict of the Genera Plantarum. In 1903 this careful student reverted to the view of Decandolle, and two years later definitely Jan.~Marcu, 1918, resuscitated Echeveria, which as defined by him, includes some sixty species, mostly Mexican, though some occur in Central America, a few in South America, and one is met with in Texas. It has to be noted, however, that _while he accepts the view of Decandolle in preference to that of Bentham and Hooker, the character on which Dr. Rose lays greatest stress is that pointed out in the Genera Plantarum ; Echeveria, Rose, as contrasted with Lcheveria, DC., must consequently be held to include several South African plants with a pentagonal corolla. This suggests consequences which need not be discussed in connection with /. setosa, the species now figured, which has, so far, only received a name in the genus Echeveria. This plant, readily distinguished from all its congeners by its setose leaves, was discovered in 1907 by Dr. C. A. Purpus on the Cerro de la Yerba, near San Luis Tultitlanapa, Puebla, South Mexico. Plants were pre- sented to Kew in 1910 by Dr. Britton, New York Botanic Garden, and in 1912 another was acquired from Messrs, Haage and Schmidt, Erfurt. From the latter, which flowered in 1914, our figure has been prepared ; two smaller leaves have been added to the plate from a plant presented by Dr. Britton. In England £. setosa can only be grown under greenhouse conditions. It flowers regularly and produces offsets freely. DeEscription.—Herb, succulent, stemless.

SEAN. ; The plant figured here under the name of Petunia integrifolia (though much better known as P. violacea) Jan.-Manrcg, 1918. first appeared in our gardens in 1831, having been raised from seeds sent to the Glasgow Botanic Garden by John (by some writers erroneously called James) Tweedie, who was at that time residing in Buenos Aires. The genus, now comprising twenty-nine species, was established in 1803 by Jussieu who, at the same date, described two species, P. parviflora and P. nyctaginiflora. There was.an interval of nearly thirty years before the third species, the subject of this note, was discovered. P. nyctaginiflora, which appears to have been in cultivation in the Jardin des Plantes, Paris, in 1820, was figured at t. 2552 of this Magazine in 1825, yet it seems to have been so far over- looked when Sir William Hooker described Tweedie’s new introduction six years later that the latter was not recognised as belonging to the same genus, and was published at t. 3113 as Salpiglossis integrifolia, the figure then given being scarcely a faithful representation of the species. The plant immediately became a favourite. Pretty and graceful as it was in itself its possibilities as a subject for crossing with P. nyctaginiflora were quickly -Tealised. Florists took it up with remarkable success ; artists repeatedly made drawings of it, and often poor ones, and botanists repeatedly described it, giving it at least nine names under five different genera. A hybrid was first obtained in 1834 by a nurseryman named Atkins of Northampton, and this was figured and described in Sweet’s Brit. Fl. Gard. ser. 2, vol. iii. t. 268 as Nierembergia Atkinsiana. Many forms of the hybrid soon appeared in gardens, and three were figured at t. 3556 of the Botanical Magazine. Details as to the evolution and history of the Petunia have been given by L. H. Bailey (Survival of the Unlike, p. 465), Le Texnier (Rev. Hort. 1908, p. 377) and Lotsy (Archives Néerlan- daises, ser. 3 B, vol. ii. p. 221). The true P. integrifolia disappeared from cultivation, though plants passing under the name of /. vivlacea were still met with in collections. The P. violacea which has been cultivated in the Chelsea Physic Garden for many years—it was found there when Mr. Hales became Curator in 1899—is quite distinct from the true plant. It has an erect habit of growth, rather like that of P. nyctaginiflora, and bright rose-coloured flowers, with a whitish throat and a pallid exterior; the corolla-tube is rather longer than that of P. integrifolia, and is funnel-shaped rather than ventricose. It agrees with the description of P. violacea var. “ Gloire de Segrez’”’ in Vilmorin-Andrieux, Les Fleurs de Pleine Terre, ed. 3, p. 848, which was raised from a garden Petunia known as “ Marquis de la Ferté.”’ It is said to reproduce itself exactly by seed, and is believed to be the same as P. violacea oculata, Hort., and P. ‘‘ Countess of Eliesmere.”” In 1911 an effort was made by Kew to secure the re-introduction of the true P. integrifolia from South America, and a request for seeds was sent to Sir Reginald Tower, His Majesty’s Minister at Buenos Aires, who had on many previous occasions given invaluable help to the establishment. The trouble he gave himself in consequence of this request seemed endless, and amongst others whom he interested in the search for the plant should especially be mentioned Mr. Carlos Thays, at that time Director-General of Public Parks, Buenos Aires, and Mr. C. E. R. Rowland, Vice-Consul at Monte Video, since 1916 Vice-Consul in Mexico, where, we deeply regret to hear, he died in 1917. Mr. Rowland was at last successful in obtaining seeds of both P. integri- folia and. P. nyctaginiflora from a virgin district on the banks of one of the small tributaries of the River Plate in Uruguay, and these reached Kew in September, 1916. convergentia, lineari-lanceolata, acuta, 7 dm. longa, 2 cm. lata.

This is one of two closely allied species which have been separated from the genus Kentia, Bl., on account of Aprit—Jung, 1918. ~ having numerous stamens (Kenfia having only 6), and because of the absence of staminodes from the female flowers. H. Belmoreana, like its ally, H. Worsteriana, is confined to Lord Howe Island, where it was reported by Messrs. C. Moore and Carron, its discoverers, as common at altitudes below 1,000 feet. Its specific name is in honour of the Right Hon. the Earl of Belmore, who was Governor of New South Wales in 1868. The flowers of H. Belmoreana, as stated by F. Mueller (Fragm. viii. 234), are extremely difficult to distinguish from those of H. Forsteriana, which has been figured at t. 7018 of this work under Kentia, and has there been referred to the species elmoreana. The pinnae of the true HH. Bel- moreana, however, converge upwards, while those of H. Forsteriana are drooping and proportionately broader, thus giving the two species a very different appearance. In addition to this //. Belmoreana does not attain so large a size before it flowers as //. Forsteriana does. Ina letter addressed to Kew in 1892 Mr. Charles Moore called attention to the difference in the fruiting spikes of the palms, those of //. Belmoreana being twice as long as those of H. Forstvriana, solitary to their respective sheaths and in appearance unisexual, whereas in //. Forsteriana the spikes are several united at the base within a common sheath, each spike being manifestly 2-sexual. The apparently unisexual nature of the spike in H. Belmoreana is, however, deceptive and is due to the length of time which elapses between the maturing of the male and the female flowers respectively. In each trio of flowers along the spike the two male flowers first appear in close contact, the female flower which is situated between each pair of males being then but slightly developed and deeply seated in the pit of the spadix. The male flowers readily disarticulate and give place to the slowly developing female one. ‘The introduction of H. Bel- moreana to cultivation in this country took place in 1872, and it has since been as extensively cultivated as an orna- mental plant as its ally H. Forsteriana. The plant from which our figure has been prepared was purchased when small from Messrs. F. Sander and Sons, St. Albans, and has grown along with H. Forsteriana, in the Mexican House at Kew. Both palms require an intermediate temperature ; their suitability for use as decorative plants is due to the fact that they bear rough usage better than most palms. They are both raised from seed imported from Lord Howe Island. Description.—Tree, reaching a height of 35 ft. ; stem slender, marked with annular scars, thickened at the base.

In 1908 a large clump of Bulbophyllum Ericssonii, Kranzl., from the collection of the Hon. Walter Rothschild was purchased for the Kew collection. Since then it has produced flowers on various occasions; these have agreed with the description of B. Evicssonii by Dr. Kranzlin in the Gardeners’ Chronicle in 1893, and with the figure of that species at t. 8088 of the present work from a plant belonging to the collection of the late Sir Trevor Lawrence. In July, 1916, however, the clump produced a different inflorescence, which showed that it includes a second species, so similar in habit to B. Eriessoni that its presence had remained unsuspected. The figure now published was prepared from the inflorescence in question, and its comparison with our t. 8088 will show Aprit-JuneE, 1918. how close is the general resemblance of the two species. Information kindly supplied by Messrs. Sander and Son, St. Albans, indicates that all the plants of B. Eriessonii now in cultivation belong to the original importation by that firm in 1893, and suggests that B. L7ricssonii has only been collected once. The history of B. sociale, now figured, may therefore be regarded as identical with that of B. Eriessonii which was forwarded to Messrs. Sander from Bencoolen, on the western coast of Sumatra Its locality should therefore be somewhere in the district in which fafflesia Arnoldi was discovered. The collection made in this district by Sir Stamford Raffles and his friends Messrs. Arnold and Jack was lost in 1824 owing to a fire at sea. No serious attempt has ever been made to replace it, and very little is known of the flora of the dis- trict in which B. Ericssonii and its companion, B. sociale, appear to have been obtained. The species with which B. sociale appears to be most comparable is B. galbinum, Ridl., a native of the Malay Peninsula, which, however, has spreading, not converging, perianth-segments. At Kew &. sociale is grown in a tropical house, and does well under the cultural treatment suitable for B. virescens, J. J.Sm., and other Malayan species.

The handsome Primula here described is very closely allied to P. sino-mollis, Balf. f. & Forr. From a series of specimens of that species communicated to Kew by Professor Bayley Balfour it differs most markedly in its much shorter corolla-tube which scarcely protrudes beyond the tips of the calyx-lobes. According to a letter » from Professor Balfour, P. sylvicola, as the name implies, grows in woods, whilst P. sino-mollis favours pastures. P, sylvicola was collected by Mr. G. Forrest in Western China, and seed sent by him was first raised by Messrs. Wallace and Company, Colchester, from whose establishment the plant now figured was obtained by Kew in 1916 under the name here published. This plant flowered in a greenhouse in March, 1917, and ripened seed APRIL-JUNE, 1918, from which a stock has been raised. The species appears to be short-lived under cultivation and is best treated as a biennial. The flower-spikes reach a height of about two feet, and as the whorls of flowers develop in slow succession the plants remain in blossom for about three months in spring. At Kew this species is too tender for cultivation out of doors. Description.—Herb, rootstock fleshy.

The genus Melicytus comprises five or six species all of which, excepting that here figured, are restricted to New Zealand and the neighbouring islands. J. ramiflorus, originally discovered during Cook’s first voyage, 1768-71, occurs in both the North and South Islands of New Zealand, in Stewart Island and the Kermadec Islands, and is everywhere abundant up to an elevation of 3,000 feet. It was collected in the island of Eua, Tonga Islands, by Mr. J. J. Lister. Miss L. 8. Gibbs, during Aprit-JuUNE, 1918, her visit to the Fiji Islands in 1907, found it at Nadari- vatu, Viti Levu, at an elevation of 2,700 feet. It has been recorded from Norfolk Island, but the material from this locality, collected by A. Cunningham, Milne and Backhouse, and preserved in the Kew Herbarium, does not quite agree with that from New Zealand. The Norfolk Island plant was described as Hymenanthera oblongifolia, A. Cunn. (Hook. Lond. Journ. Bot. vol. i. p- 124) in 1842, and this has been identified, but certainly not correctly, with H. dentata, R. Br. It is evidently a Melicytus and must be very closely allied to M. ramiflorus. The material for our figure was communicated by the Rev, Arthur T. Boscawen of Ludgvan Rectory, Long Rock, Cornwall, the fruit in November, 1916, and the flower in June, 1917, from plants cultivated in the open raised from seed received from New Zealand in 1907. At Ludgvan the plant has withstood ten degrees of frost without serious injury. The species, which was intro- duced into England in 1822, is represented at Kew by plants in the Temperate House, one of which is planted out in ordinary garden soil, and is now a bush about 10 feet high. Flowers are occasionally produced at Kew, | but not fruit. _DEscript1on.—Shrub of considerable size or at times a tree up to 30 ft. high,. dioecious, glabrous; trunk 1-2 ft. in diameter, bark grey, closely lenticelled.

Sophora japonica was introduced to this country from China in 1753 by James Gordon, a nurseryman of that time at Mile End. It is not believed to be indigenous to Japan, although much cultivated there. Five trees_ of the original introduction were planted at Kew, one at least of which remains. The Sophora is one of the most ornamental of all hardy trees. Its foliage is elegant and richly luxuriant, and flowering as it does in September when no other large tree is in blossom, its beauty Is very conspicuous. It does not as a rule flower until it is » thirty to forty years old, and is always seen at its best Z after a hot summer. The pods are rarely developed in England; the only time we have seen them in recent years was in 1911. Even then the seeds do not ripen, JULY-SEPTEMBER, 1918. although they do so in Central and Southern Europe. Every part of the tree is permeated with a cathartic principle. The tree likes a rich loamy soil and should be planted in full sun. If we exclude the Ldwardsia group of Svphora, which is confined to the Southern Hemisphere and is well distinguished by the erect, nearly uniform petals and small, more numerous leaflets, S. japonica is distinct from ail other species cultivated in this country in being a tree. S. afinis, Torr. & Gr., a small North American tree, differs in its axillary racemes and its 4—8-seeded pubescent fruits. Description.— Tree, 50-80 ft. high, the bark of the trunk much fissured in old specimens ; branchlets bright brown, more or less pubescent, especially when young. Leaves deciduous, alternate, imparipinnate, 6-10 in. long; rachis pubescent, swollen at the base. Leaflets 9-15, ovate, acute, apiculate, rounded at the base, 1-3 in. long, 3-3 in. wide, dark glossy green above, glaucous and furnished with adpressed pubescence beneath ; petiolules z's in. long, pubescent ; stipules sickle-shaped, } in. long, caducous. Panicles terminal, pyramidal, 4-8 in. high and wide. Flowers creamy white, 2 in. long, opening in September. Calyx campanulate, with five shallow triangular teeth, minutely pubescent.

It bears a close general resemblance to the well-known 2. pyrenaica which, however, is usually more robust in growth and has larger flowers with yellow apiculate anthers. Its distribution ‘is particularly inter- esting. While the original /. pyrenaica and the four forms -—for they are really nothing more—of that species which have been regarded as distinct by Jordan, occur only in the Iberian Peninsula, extending as far south as the Province of Jaen in Spain, all the other European Gesneriaceae, comprising Ramondia serbica, R. Nathaliae, Pané. & Petrov., &. Heldreichii, Janka, Haberlea rhodo- pensis, Friv., with its variety virginalis, and /1, Ferdinandi- Juty-SEPTEMBER, 1918, f Coburgu, Urumoff, are confined to the Balkan Peninsula and Thessaly (Mount Olympus). 2. serbica was originally discovered on Mount Zlot in Southern Serbia by Pancic, growing on rocks in calcareous soil. It has since been found in other parts of Serbia and in Albania, but, as pointed out by Adamovic¢, the specimens from Albania, collected by Baldacci, have been distributed and recorded under the name of 2’. Nathaliae. The record for Bulgaria by Velenovsky is shown by Derganc to be based on an incorrect identification, the plant supposed to have been Ramendia serbica being in reality Haberlea rhodopensis. f. Nathaliae, regarded by some authorities as merely a variety of /’. serbica, is, according to Adamovié, a distinct species, differing in having broadly ovate leaves which are narrowed almost equally to base and apex, regularly tetramerous flowers, a patelliform corolla and. longer anthers. L, serbica has long been in cultivation at Kew, where it is established along with 2. pyrenaica in a loose stone wall in the Rock Garden, thriving well in a shaded situation and flowering annually during May and June. A few plants are also grown ina cold frame to flower earlier in the Alpine House. It may be propagated by its seeds, which ripen freely. The plant from which our figure has been prepared was communicated by Sir F. W. Moore from the Royal Botanic Garden, Glasnevin, in June, 1917, Drscription.—Herb, small, stemless, perennial. Leaves rosulate, spathulate or obovate, irregularly toothed, rounded at the apex, narrowed at the base toa broad petiole, including the petiole 14-23 in. long, 2-11 in. wide, at first uniformly and densely rusty-hirsute with long hairs, ultimately villous above and densely rusty-hirsute beneath.

The striking Gongvra here figured is one of the plants which formed part of the collection of the late Sir ‘Trevor Lawrence, presented to Kew by the late Lady Lawrence in 1914. This particular plant bore no name and no indication of its origin. When it subsequently flowered at Kew it was not possible to identify it with any named specimen, though it was found to match so closely an unnamed one belonging to the herbarium of the late Consul Lehmann as to leave little doubt that the two are forms of one species. The Lehmann spécimen was collected in 1899 on the banks of the Timbiqui in the _ JuLy-Seprempsr, 1918. — forests of Cotejo, Colombia. There are several species of the. genus Gongora only known from the descriptions written by the late Professor Reichenbach. The plant now described cannot be identified with any of these, and it is therefore regarded as a new species for which the name G. latisepala is employed with reference to its relatively broad sepals. It bears a certain resemblance to (7. yratulabunda, Reichb. f., figured at t. 7224 of this work, but in addition to having sepals of a different — shape that species may readily be distinguished by the absence of the pair of short horns at the base of the hypochile of the lip, a character of some value in this genus. In the possession of these horns our species comes nearer to G. odoratissima, Lem., which, however, has longer and narrower unspotted sepals. At Kew G. latisepala thrives well in the tropical house under the conditions suitable for its congeners and for the species of Stanhopea. Description.—Herb, epiphytic.

Fructus haud visus.—J. Hurcuison. According to Messrs. Rehder and Wilson Rhododendron argyrophyllum, Franch., “is one of the commonest species in Western Szechuan and shows much variation.” The material of this species in the Kew herbarium bears out this statement. But the variations are confined to single organs and are somewhat inconspicuous. They are simple morphological fluctuations, readily recognis- able, but not of specific importance. The authors cited have accorded the rank of varieties to two of these fluctuations: cupulare, with rather smaller cup-shaped flowers; and vmeiense, with slender drooping pedicels and a rather darker indumentum on the leaves beneath. Both of these varieties agree with Mr. Franchet’s JuLy-SEepremper, 1918. riginal type in having hairy filaments ; that now figured differs orth all thies in having the filaments without hairs. This is a difference which, in the genus Lhodo- dendron, usually is specific; in the present instance it certainly does not possess that value. There is within &. argyrophyllum a fifth recognisable Be collected by Mr. Wilson on Wa-shan (Wilson, n. 121 ), which has glabrous filaments like those of vav. leiandrum, but has some of its calyx-lobes over one-third of an inch in length. The nearest ally of £2. argyrophyllum is ft. hypoglaucum, Hemsl., described at t. 8649 of this work, where the close relationship of the two species 1s discussed. The plant from which the flowering branch now figured was cut on 5 May, 1916, was raised from seed received from the Arnold’ Arboretum and sown in 1909. This seed was collected in Western Szechuan in 1908 by Mr. Wilson and was received as his n. 1353. This number, however, belongs in part to R. Wiltonii, Hemsl. & Wils., and it may be that in some collec- tions f. argyrophyllum var. leiandrum bears the name ft. Wiltonit. The plants at Kew are rounded, much branched bushes, now about afoot and a half to two feet high, slow of growth and sturdy. The species is appa- rently very hardy and did not suffer in the least from the severe winter of 1916-17, The flowers do not open until late April or early May, and thus have a better chance of escaping inj ury from late spring frosts than those of many of the new Chinese species.

Govenia tingens, the subject of our illustration, was originally described and figured by Poeppig and Endlicher in 1838 from material collected in the dense forests of eastern Peru at Cuchero and Pampayaca. A specimen collected at Chacapoyas by Matthews is probably iden- tical with the original plant, and examples of a Govenia introduced from Peru by Messrs. Sander and Sons, St. Albans, through their collector, Forget, which flowered in February, 1915, were tentatively referred to G. tingens. The genus Govenia is a very natural one, most of the members of which are extremely similar in habit ; indeed, Lindley has remarked that among the genera of Orchids there is not one whose species are so difficult to distinguish from each other. In a dried state they are so much alike if the specimens have been similarly prepared, or they may vary so much in appearance, owing to the JuLY-SEpremBer, 1918. manner in which their flowers shrink, when they have been prepared differently, that their recognition is at times hardly possible. One result of this has been that the Peruvian (. tingens has been actually recorded from Caracas, a statement that is at least doubtful, because there is a species from Caracas, described by Lindley as G. fasciata, »which is clearly distinct from G. tingens. The chief difficulty connected with G. tingens lies in our imperfect knowledge of the original plant. The specimen figured was taken from a plant purchased for Kew in 1912 at a sale held by Messrs. Prothero and Morris, the floral details of which agree well with the original figure. The plant is grown in a tropical house along with species of Calanthe, and flowers in early spring. Itis most readily comparable with G. Gardneri, Hook., figured at t. 3660 of this work. Descriprioy.—Herb, terrestrial. Stem erect, short, 2-foliate.

The specimens on which the original account of Linum elegans was based were collected on Mount Parnassos by Sprunner, who suggested the name it bears, and on Mount Olympus by Heldreich. It occurs, however, elsewhere in Greece, and has been gathered on Mount Ida in Asia Minor. Before Boissier published his description under Sprunner’s name, it had also been met with by Aucher, who suggested for it the name US iberidifolia, which was similarly taken up by Planchon. Besides the specimen to which Aucher gave that name, this collector had also gathered it on Mount Athos, and Planchon, when he monographed the genus in 1848, after having referred to the Mount Athos plant under L. caespitosum, Sibth. & Sm., finally decided, and with reason, that it JuLy-SEPTEMBER, 1918. too may be included in the present species. The nearest allies of L. elegans are L. flavum, Linn., a species which is to be met with in south-eastern Germany and southern Russia, and L. campanulatum, Linn., a species confined to southern France. From the former our plant differs in its smaller leaves, from the latter in its smaller flowers. The plant from which our figure has been prepared was presented to Kew by Miss Willmott, from her garden at Warley Place, Great Warley. It is not yet possible to say whether it will prove hardy at Kew. It flowers freely in May in a frame, but does not ripen its seeds. It can, however, be propagated readil y by means of cuttings.

Alnus jirma is a variable species which is widely dis- tributed in Japan, and with A. Alnobetula, Hartig — Juty-Sepremper, 1918, (A. viridis, Regel), belongs to the section of the genus characterised by having the female inflorescences in terminal racemes, which make their appearance in the spring, while in all the other known species they are solitary or racemose in the axils of the leaves and appear in autumn. A. firma is moreover easily recognised by its leaves having numerous straight almost parallel lateral nerves, which in the variety mu/tinervis are as many as 18 to 24 on each side of the midrib. In this respect the leaves much resemble those of some hornbeams. Though sometimes found as a bush, at others it appears as a small tree, having long, slender, spreading branches, which give a graceful effect. A tree at Kew has now reached the height of nearly 30 ft., and has a trunk about 6 inches in diameter. Three varieties have been distinguished, each by some authorities regarded as species. The variety muiltinervis (A. pendula, Matsu- mura) has longer, more acuminate, doubly serrate leaves with 18-24 pairs of lateral nerves, and smaller cones in a pendulous raceme. This was the first representative of the species introduced into this country, it is believed by Mr. John Gould Veitch in 1862. The variety Sieboldiana (A. Sieboldiana, Matsumura) has solitary cones, which are larger than in the other varieties; its leaves are broader and fewer-nerved than in the variety multinervis, and its young branchlets, which are pube- scent in the variety Yasha, are glabrous. 1. jirma var. Sieboldiana is not in cultivation. The variety now figured was introduced into America by Professor Sargent in 1892, and through him to Kew in 1893. At Kew it thrives well and makes a very elegant small tree, very distinct owing to its handsome, hornbeam-like leaves. It enjoys a deep, stiffish, loamy soil. Professor Matsumura records it from many localities in the island of Hondo, from one in Sikoku and from three provinces in Kiushiu. Its Japanese name is Oba-minebari. It is presumbly of this variety that Professor Sargent speaks in his “Forest Flora of Japan” as “largely planted along the margins of rice-fields near Tokyo to afford support for the poles on which the freshly cut rice is hung to dry.” It has hitherto been quite a rare tree in English collections, but it well deserves attention and ought soon to be more frequently seen as it produces seeds plentifully at Kew. Description.—Shrub or small tree, reaching 30 ft. in height; branches very long, slender, spreading ; twigs with numerous conspicuous lenticels, at first pubescent, at length becoming glabrous; buds sessile, long-conical. Leaves petioled, ovate-lanceolate, acute or shortly acuminate, base rounded and often slightly unequal, thick-serrulate, glabrous above, adpressed-pubescent on the nerves beneath, 23-3 in. long, 1-1} in. wide above the base; lateral nerves 10-16 on each side of the midrib, conspicuous, nearly paralled, sunk above like the midrib, raised beneath ; petiole often nearly } in. long, pubescent.

BEAN. We are indebted for the material from which the figure in the accompanying plate has been prepared to Sir Edmund Loder of Leonardslee, Horsham, who supplied the flowering spray on 12 June, 1917, and the fruit during the following November. Save for the specimens thus gathered from the plants at Leonardslee, Stewartia serrata is only represented in the Kew herbarium by a single leafy spray and a solitary detached flower, both collected in Japan in 1863 by the late Mr. Maximowicz. From the cultivated form now figured Maximowicz’s specimen differs in having the. petals velvety outside on the upper half, and in having the shoot quite glabrous, as also are the leaves except for the axil-tufts of tomentum beneath. In all other respects the two specimens appear to agree. We have failed to ascertain at all definitely the dimensions this Stewartia JULY-SEPTEMBER, 1918, is capable of attaining. Maximowicz states that it had been reported to him that it may reach a large size: “arbor dicitur altissima, 4 pedes usque crassa.” In spite of this, however, we believe it will never become more than a small tree in this country. It seems to be quite hardy both at Leonardslee and at Kew, and like its allies will no doubt thrive well elsewhere in either loamy or peaty soil. In the absence of seeds it may be propagated by cuttings made of fairly firm wood in July or August. The nearest ally of S. serrata is probably S. sinensis, Rehd. et Wils., a Chinese species first dis- covered by Professor A. Henry, and first introduced to cultivation by Mr. E. H. Wilson in 1901. This species, however, is readily distinguished from S. serrata by its pilose ovary, its monadelphous stamens and its leaves without pubescence in the axils of the veins on the undersurface.

A. Roure. The Polystachya here figured is an unusually showy member of its large and somewhat polymorphic genus. Within that genus it belongs to a small group. of species the original representative of which is P. elastica, Lindl, but which is now known to include, in addition to P. Pobeguinii described above, two other forms from tropical Africa, P. liberica, Rolfe, and P. Smytheana, Rolfe. The species which forms the subject of our plate was discovered by Mr. Pobéguin in the peninsula of Ninkan and again at Labé in French Guinea, and was described from this material as Epiphora Pobeguinn by Mr. Finet, who took the opportunity thus offered of suggesting the restoration of the genus Epiphora based JuLy-SerremBeER, 1918. by Professor Lindley on the South African species described at t. 5886 of this work as P. pubescens, Reichb. f. There is, however, no outstanding character by which Epiphora can be generically distinguished from Poly- stachya, and even if this had been the case there is the further difficulty that the present species is not very closely allied to P. pulvscens, but belongs to another section of that rather variable genus. The species is reported to have been in cultivation at Paris from the original specimens. The plant now figured was obtained for the Kew collection from Messrs. Sander and Sons, St. Albans, and flowered at Kew in October, 1913, Another example of P. Pobeguinii flowered at Glasnevin in November, 1917. The species is remarkable for its bright rose sepals and petals and for its strongly recurved lip which has a darker purple front lobe, and a prominent cushion-like, bright yellow crest on the disk. It thrives in a tropical Orchid House if planted in a mixture of peat fibre and sphagnum. It should be kept dry when not in active growth. Descrirtion.—Herb, epiphytic ; stems terete, strict, 4-6 in. long, thickened at the base into ovoid-globose pseudobulbs, clothed with short sheaths and bearing few leaves. Leaves 3-7, distichous, spreading or somewhat erect, lanceolate, rather acute, glabrous, 3-4 in. long, 1-1 in. wide. Scapes erect, about 8 in, long, clothed below with short sheaths ; racemes many-fiowered, rachis slightly puberulous; bracts spreading, ovate, acute, glabrous, concave, with finely denticulate margin; pedicels about tin. long.

Since then the species has been met with by Lorent, Hauss- knecht and others in the Orient, where it inhabits a somewhat limited area which extends from Aintab and Nisib in Northern Syria to Kharput and Diarbekir in Kurdistan. Within this area it is said to grow chiefly on calcareous soil. The colour of its flower varies, sometimes in the same locality, from rich yellow to pure red or nearly scarlet. Haussknecht, who collected both colour-forms at Aintab and Nisib, was inclined to attri- bute the colour of the red form, which we now figure, to the ferruginous nature of the loam in which he found it growing, though when describing the yellow form as Hypericum laeve, he and Boissier nevertheless accorded the red one the status of a variety, while Hochstetter treated specimens of the red flowered plant, collected by JULY-SEPTEMBER, 1918. Lorent, as a distinct species, //. rubrum. There is, however, no character other than the colour of the flowers by which the two can be distinguished, and we have therefore reverted here to what would seem to have been the view taken by Haussknecht when he examined the two plants as they grew under natural conditions. The plant which forms the subject of our plate flowered in the collection at Kew in June, 1917. It was obtained from Messrs. Bees, Limited, of Neston, who exhibited it in flower at the Holland Park meeting of the Royal Horticultural Society in June, 1914. With Messrs. Bees, at Sealand, Cheshire, the plant withstood two successive winters and grew to a height of eighteen inches, but at Kew it has proved to be tender and has died after flowering. Though it continues in flower for about two months, it has failed to ripen seeds at Kew, but it has been successfully propagated by means of cuttings made from young shoots. The yellow-flowered form, regarded by the authors of the species as the typical one, has not yet been introduced to English gardens. The nearest ally of H. laeve is the Arabian fH. scabrum, Linn., from which our plant is readily distin- guished by its smooth and glabrous, in place of rough and glandular stems. Description.—Herb, perennial, sending up several stems, in wild plants 1-2 ft. in height; stems terete, virgate, smooth and glabrous, with many axillary branchlets. Leaves linear or on the stouter stems linear-oblong, obtuse, usually and especially on the twigs with revolute edges, dotted with transparent glands, }-} rarely 1} in. long, ,.-1 in. wide, those of the twigs owing to their much revolute edges often under me in. across. Panicle shortly ovoid, rather corymbose and dense, very rarely elongated and more open; bracts ovate-oblong or oblong, dotted with black glands.

Petals spreading, elliptic or oblong-elliptic, shortly clawed, towards the apex shortly fringed with black glands, }-! in. long, golden-yellow, or yellow with a reddish tinge or, in the form figured, scarlet-red, as are the filaments and the styles. z , TAB. 8773.— Fig. 1, a leaf; 2, flower; 3, a group of stamens; 4 and 5, single stamens ; 6, pistil :—all enlarged. | 2 Vincent Brooks.Day &SonL¥ imp del.

This seed had been obtained in Bhutan by Mr. Cooper when collecting there on behalf of Messrs. Bees, Limited. This species, S. /ookeri, was first col- lected by the late Sir J. D. Hooker in July, 1849, in the Sikkim Himalaya near Tungu at altitudes of 12,000- 14,000 feet above sea-level. It was met with again by Mr. H. J. Elwes in 1877, and since then it has been gathered in the vicinity of Ta-chien-lu in Western Szechuan by various French and British collectors. This is by far the most handsome of the species of Scahiosa met with in the Himalaya, and is readily JuLty-SepremsBeER, 1918, recognised among them by its radical leaves, and _ its leafless, scapigerous one-headed peduncles. At Kew it has flowered in an open border in July and has proved quite hardy, making vigorous growth in spring after a winter, unprotected, out-of-doors. What appears to be another form of the species with light yellow flowers has been gathered in the neighbourhood of Chumbi, immedi- ately to the east of Sikkim, by one of the collectors employed by the late Sir George King. The same form has alsq been found near Lhassa in Tibet by Captain H. J. Walton.

The very distinct Rhododendron now figured is a native of Western Szechuan, where it occurs at altitudes of 9,000—10,000 feet above sea level. It was first collected near Moupine, in 1869, by the Abbé David who, noting it as remarkable for its rounded leaves, used for it the name &. rotundifolium published, but without a full description, in 1873. In 1877 Professor Decaisne sup- plied an account of the plant under the name R. orbiculare, and although the late Mr. Franchet took up the Abbe’s OocroBER-DECEMBER, 1918, name in 1888, that of Decaisne has, with reason, been definitely adopted by Messrs. Rehder and Wilson. The species was first introduced to cultivation in this country by Messrs. J. Veitch and Sons from seed obtained for them by Mr. E. H. Wilson in 1904. It is, however, compara- tively rare in gardens, owing to the circumstance perhaps that it did not thrive very well at Coombe Wood, so that the stock in the country was for a time somewhat scanty. Two plants were obtained for Kew from the Coombe Wood nursery in 1908, and although they have proved hardy in so far that they have not been injured by winter cold, they have not thriven well. They have flowered occasionally, and have ripened seeds from which piants have been raised, but after ten years they still remain small and stunted. The species, however, is well adapted to the milder damp climate of the south- west of England, and in the collection of Me J, Williams at Caerhays Castle it forms rounded bushes over five feet through, many of which thrive well when given a rather open well-drained situation facing the east. The first plant to flower at Caerhays did so on April 20, 1910, and Mr. Williams, to whom we are indebted for the material for our plate from a plant that blossomed at Caerhays in 1914, regards R. orbiculare as one of the most remarkable of the Rhododendrons obtained by Mr. Wilson. “TI think,’ he writes, ‘ I would prefer to keep.a good plant of it if I were only to be allowed one of the whole family.” Mr. Williams, in the same letter, says, “‘ Wilson told me he found it with his glasses on the far side of a deep valley, and that it took him a day and a half’s journey to get there.” From Caerhays seeds of £2. orbiculare have been distributed freely, while the species has also been propagated there by the slower process of establishing cuttings. In addition to this LR. orbiculare has been crossed with A. discolor, Franch. ; the hybrids have flowered, and although no improvement on &. orbiculare they much resemble that parent and are more robust. The species is readily distinguished from other known Chinese ones by its suborbicular, deeply cordate leaves borne on unusually long petioles. Its nearest ally is R. Fargesii, Franch., figured at t. 8736 of this work, which differs mainly in its leaf characters. Description.—Shrub, 9-10 ft. high; twigs stout, shining, glabrous, laxly leafy towards the tip; axillary buds narrow-ovoid, obtuse or somewhat acute, glabrous. Leaves elliptic or elliptic-orbicular, sometimes slightly emarginate or mucronulate, deep cordate at the base with the lobes overlapping, 2-4 in. long, 13-8 in. wide, coriaceous, glabrous, green above, glaucous and finely veined beneath; midrib flat above, very conspicuous beneath, about ;; in. broad at the base, becoming very slender near the tip; lateral nerves about 10 on each side, slender, branching towards the leaf-margin, inconspicuous beneath; petiole stout, nearly cylindric, over 2 in. long, shining, glabrous. Inflorescence terminal, open, about 10-flowered. Flowers nodding, rose-car- mine ; pedicels 1-1} in. long, glabrous. Calyx small; lobes short, with glandular margins. Corolla wide-campanulate, without scales; tube 13 in. long, 1} in, wide at the mouth; Icbes 7, nearly erect or spreading, short, widely emarginate. Stamens about 18, unequal in length, rather shorter than the tube; filaments glabrous, whitish ; anthers very dark brown, 75 in. long.

The little Mesembryanthemum here figured is a member of the Sphaeroidea section of the genus, characterised by the leaves being reduced to a single pair, united to form a more or less globose or ovoid mass termed a “‘corpusculum.” It is a native of Great Namaqualand, where it was collected by the late Professor H. H. W. Pearson of Cape Town in the course of the Percy Sladen Expedition to the Great Karasberg Range. In its native habitat it grows on sandy plains at an elevation of 4,300 feet above the sea. Living plants were presented to Kew by Professor Pearson in the early part of 1913, and had not yet flowered when in June, 1914, a description of the species was published by Mr. N. E. Brown. In October, 1915, however, a plant flowered in the collection of suc- culents at Kew and admitted of the preparation of our illustration. The nearest ally of this Namaqualand plant is M. Leslici, N. E. Br., a native of the Transvaal in which, however, the leaves are more completely confluent into OcTroBER-DzcEeMBER, 1918. an obovoid truncate corpusculum with markings of a somewhat reticulated character, while the petals are longer, more reflexed and relatively narrower. Description.—Herb, fleshy, small and stemless, with a rather long tap-root. Leaves 2, connate beyond their middle to form a fleshy corpuscle. Corpuscles at times 1-2, at times several and caespitose, obconic, 1-13 in. long, truncate and about 1 in. wide at the top, which is marked by the transverse fissure due to the incomplete union of the component leaves, smooth, glabrous, with small rounded dark green spots on the tawny apical surface, uniformly dull grey- purple on the sides; the transverse fissure about din. deep.

Berger on JV. bilobum, Marloth, but which is now known to include at least three other species: MJ. gracilipes, Bolus; J/. stylosum, N. E. Br., figured at t. 8595B of this work; and Mf. Elishae, the species here described. The section is characterised by the very fleshy, somewhat elongated leaves being more or less united at the base but remaining free above so that the resulting corpus- culum is more or less heart-shaped. The precise habitat of this species in South Africa has not been recorded. It appeared originally in this country in the collection of Mr. G. Elisha, Canonbury Park Road, a keen cultiva- tor of species of Mesembryanthemum. The specimen here depicted flowered with Mr. Elisha in October, 1916, and was described by Mr. N. E. Brown. Since then Mr. Elisha has presented a plant to Kew. Mr. Brown has remarked that the nearest allies of M. Llishae are M. bilobum and M. stylosum, but it differs from both in its dwarfer and relatively shorter growths, which form OcroBER-DECEMBER, 1918. very compact clusters. The neat habit and the markedly glaucous green with scattered darker dots of the half- connate leaves give it a pleasing appearance. The flowers are bright yellow, expanding in full sunshine and closing at night. Description.—Herb, succulent, dwarf; root descending. Leaves 2, connate to their middle to form a fleshy corpuscle. Corpuscles densely tufted, 2-1 in. long, 4- in. thick, somewhat obovoid, much compressed at the apex with erect keeled lobes, glabrous, bluish-green, indistinctly marked with darker dots.

The example of Primula sinopurpurea which is here figured was raised at Kew from seed collected by Mr. G. Forrest in Yunnan and presented by Mr. J. C. Williams, Caerhays Castle, in 1915. It is closely allied to the rather widely distributed P. nivalis, Pall., figured at t. 1161 of this work, but differs from that plant in its more remotely repand-denticulateleaves, which are conspicuously farinose onthe underside. In his memorable discourse on Chinese Primulas, addressed to the members of the Primula , Ocroper-DEcEMBER, 1918. ” Conference held in April, 1913, Professor Bayley Balfour remarked that the group of forms of which /?. nivalis, Pall., is the type includes no fewer than seven Chinese species, all of which, with the exception of P. albijtos, Ward, have blue or purple flowers. Of these P. sino- purpurea ig one of the most striking. It has proved quite hardy at Kew, where, planted in the Rock Garden in half-shade, it has grown well and flowered freely. The first examples to flower did so in April, 1916, and from one of these our figure was made. Examples which flowered in April, 1917, and again in April, 1918, have developed into specimens more robust than the original ones, with the flowers sometimes arranged in two whorls about a couple of inches apart, the upper whorl then producing as many as twenty flowers. In each season these plants have ripened seeds from which a new crop has been raised. Like some other Chinese Primulas, P. sinopurpurea must be treated as a biennial, for under cultivation the plants usually die after flowering. Description.— Herb, stout and frequently about 4 in. high, but sometimes larger and exceeding a foot in height. Leaves rosulate, ascending or spreading, oblanceolate, acute or subacute, narrowed at the base with a winged petiole, up to 8 in. long and 1} in. wide, thinly papery or almost membranous, repand- _ toothed, glabrous above, yellow and mealy beneath; lateral nerves ascending, aeag 8 on each side, much branched, prominent on both surfaces; «petiole broad, up to 8 in. long.

We are indebted for the flowering spray and the fruit of Stewartia sinensis now figured to Mr. H. Williams Grigg, in whose grounds at Cann House, Crown Hill, near Plymouth, it forms part of a very extensive and exceed- ingly well cultivated collection of rare trees and shrubs. There are also young examples in the collection at Kew, where they thrive well and are evidently quite hardy, since they have remained quite unaffected by the rigorous winters of 1916-17 and 1917-18, though they do not grow with the luxuriance that characterises them in the softer air of South Devon. This species was originally discovered in Western Hupeh by Mr. E. H. Wilson in 1901 when collecting for Messrs. Veitch, by OcropER—DECEMBER, 1918, ~ whom it was introduced to cultivation. It was distri- buted under the name S. monadelpha and is doubtless in cultivation under that name in various English gardens. The true S$. monadelpha, Sieb. & Zuce., is, however, a purely Japanese shrub and is readily distinguished from S. sinensis by its much smaller, scarcely angled capsules, which are only one-third of an inch wide. Another near ally of S. sinensis is S. serrata, Maxim., also a purely Japanese species, figured at t. 8771 of this work, which is even more readily distinguished from our plant by its polyadelphous stamens, its glabrous ovary, and its leaves with tufts of pubescence at the axils of the main-nerves on the under surface of the leaves. While still quite young all the species of Stewartia enjoy an admixture of peat with the soil in which they are grown, though this 1s not essential if the soil be light, warm and loamy and if it be free from lime. In the absence of seeds, the Stewartias may be propagated by summer cuttings. Desortetion.— Shrub or small tree 15 to 80 ft. high ; young shoots densely clothed with fine hairs. Leaves deciduous, usually oval, sometimes ovate- oblong, acuminate, cuneate at the base, finely serrate; 14-4 in. long, 3-1} in. wide; ciliate, bright green on both surfaces, the upper furnished at first with scattered appressed hairs, the lower glabrous except on the midrib and chief nerves; petiole hairy,}-1 in. long.

H. Lankester. Since its arrival it has thriven well in the Cactus House at Kew. It produced flowers for the first time in October, 1917, when the accompanying figure was prepared. The study of species of the Cactus family presents several difficulties. Owing to the trouble experienced in preserving them satisfac- torily they are, as a rule, but imperfectly represented in herbaria. Their determination from descriptions unac- companied by drawings or photographs is often some- what uncertain. Even where there are ample material and adequately illustrated descriptions, students of the family often are beset with doubts as regards the delimitation not only of the species themselves, but also of the genera to which they should be referred. In the present instance all the difficulties alluded to have been encoun- OcroBeR--DECEMBER, 1918. tered. There is no specimen in the herbarium at Kew with which our plant may be exactly matched. Although Mr. Lankester has not supplied any note as to the local name of this plant, we believe it to be that known in Costa Rica as the Tunilla, which is stated to bear an elongated, spinose edible fruit and fragrant flowers, and has been described by Dr. Weber as Cereus Tunilla. At all events the plant figured accords well with Weber’s account of the Tunilla and still better, perhaps, with the description given by the same author of Cereus Gonzalezii, a closely allied one subsequently regarded by Professor Schumann as merely a form of the Tunilla. This verdict of Schumann has been accepted by Dr. Britton and Dr. Rose, though these authors have deviated from both Weber and Schumann in that they regard the Tunilla as the type of a distinct genus on which they have bestowed the name Weberocereus. Whether our plant really be the Tunilla or not, it accords so well in essentials with Cereus that we have felt it desirable to retain it in that genus. The original type of Cereus Tunilla was found growing on an oak in the village of Tablon near Cartago, at a little over 6,000 feet above sea-level ; that. or C. Gonzalezii was collected at Pacayo, at a similar elevation. If, as we believe, the plant figured be Cereus Tunilla, the present is not the first occasion of its intro- duction to European collections; a young plant, grafted upon the Mexican Cereus nycticalus, Link, is reported to have blossomed at Paris in October, 1901.

Since the introduction, more than half a century ago, of O. crispum, Lindl., orchid growers have found that, among their plants of repeated importations, occasional examples, on coming into blossom, prove to belong to one or another of three species other than O. crispum. This is not surprising. Mr. Rolfe has shown (Orchid Review, vol. i. p. 277) that, in the district of Bogota in Colombia, 0. gloriosum, Lindl. & Reichb. £., O. Lindleyanum, Reichb. f., and O. luteopurpureum, occur naturally in association with QO. crispum, and the casual inclusion of one or other of the three in what was believed to be an unmixed parcel of O. crispum is intelligible. What has been more puzzling to growers has been the occurrence among their plants of forms that on flowering proved to be unlike any of the four species named. Their intermediate characters suggested that such forms must be of hybrid origin, though their precise parentage has often been in doubt. When dealing with these hybrids Mr. Rolfe pointed out that OcropeR-DEcEMBER, 1918. although they did not include a cross between 0. gloriosum and O. Lindleyanum, an instance might be anticipated, and a plant which flowered in 1904 in the collection of Mr. W. Thompson, Walton Grange, Stone, exhibited characters that led Mr. Stevens, his gardener, to conclude that it must be this natural hybrid. The characters of the plant induced Mr. Rolfe to adopt the conclusion of Mr. Stevens and to describe the form as QO. praevisum. In order to confirm the parentage of the supposed hybrid, an opportunity was taken to cross O. gloriosum and O, Lindleyanum. Several seedlings, of which O. gleriosum was the seed-parent, were secured, and the first of these to flower did so at Kew in March, 1915, when our drawing was made. As compared with the natural hybrid, that now figured has a brighter yellow ground-colour, and shows more of the influence of the female parent. It is of interest to note that O. Wilcke- anum, Reichb. f., a natural hybrid between O. crispum and QO. luteopurpureum, and O. Conradinei, Reichb. f., a natural hybrid between 0. crispum and O. Lindleyanum have now both been raised artificially ; also that QO. Adrianae, Lindl., a plant from another locality in Colombia, where 0. crispum grows in company with O. Hunnewellianum, Rolfe, has been shown by Mr. Rolfe from crosses effected at Kew to be a natural hybrid between these two species. Cultivated under the con- ditions suitable for its parents, 0. praevisum thrives as satisfactorily as they do. | Description.—Herb, epiphytic.

It had been raised from seed collected for the firm by Mr. E. H. Wilson in Western Szechuan, China, in 1904, and may be grown in various gardens under Wilson’s seed-number, 1930. The Kew examples flowered for the first time in June, 1914, and developed an abundant crop of its richly coloured fruits in the autumn of that year. Since then the plants have flowered and fruited freely, and now form bushes six to eight feet high. Being without a name, flowering and fruiting material of the species was sent to the Arnold Aboretum, where it has been examined by Dr. Schneider, who has described it as a new species, observing when so doing that “this is a very distinct species of which the taxonomic position is yet unknown. * Ocroper-Decemper, 1918, 2 As a shrub for gardens B.

The genus Diascia includes some fifty species, all of them natives of South Africa. Most of them are without horticultural value, and the only species, other than D. Aliciae here figured, known in European gardens is D. Barberae, Hook. f., which was introduced in 1870 and is figured at t. 5933 of this work. The species now described was discovered in 1903 in the Kentani district of the Transkei by Miss Alice Pegler, who met with it in damp sheltered spots at about 1,500 feet above sea-level. The material for our plate has been provided by plants OcroBER-DECEMBER, 1918. raised at Kew from seed received in 1915 from the late Professor Pearson, Cape Town. Grown in an outside border during the summer, they flowered freely in 1916. At Kew the plant is not hardy and has not ripened seeds; propagation is, however, easily effected by means of cuttings. Its nearest ally is D. Burchellii, Hiern, which also occurs in the Transkei but extends thence westward to near Cape Town; this latter species has not yet been introduced, and is unlikely to prove more effective horticulturally than that now figured, which as a decora- tive plant, although not without charm, is much inferior to the better known D. Barberae. If the flowers of D. Barberae and D. Aliciae be compared it will be observed that in both species the filaments of the lower and longer pair of stamens form a loop through which the two upper stamens are deflected, the anthers of the latter being thus placed on the lower side, the four being connivent or coherent round the tip of the style. But whereas in D. Aliciae the style and anthers are appressed to the upper lip across the sac at its base, in D. Barberae they are diverted towards the median lobe of the lower lip and stand between the mouths of the spurs. _ Desoription.—Herb, perennial, up to 2} ft. high, all parts except the inflorescence glabrous, diffusely branched.

No Mesembryanthemum to be met with in succulent col- lections is more handsome than the Jong known /. edule, figured here from material obtained by Mr. J. Hutchinson on the face of an old quarry at the entrance to Caerthillian Valley in Cornwall, where it is thoroughly naturalised in company with the Australian and Chilian species M. aequi- laterale, Haw. A native of South Africa, J. edule, in most parts of Britain, requires the protection of a greenhouse during winter. But in certain localities in Cornwall, South Devon and Jersey, it is now established OcropeR—DecemBER, 1918. as an alien, and in those parts of the United Kingdom with a similar climate the species is hardy and is seen to best advantage when planted along the top of a low wall and allowed to hang down. It thrives best if planted in poor sandy soil, and may be propagated with ease by cuttings taken at any season. The nearest ally of M. edule is another Cape species, MV. acinaciforme, Linn., figured at t. 5539 of this work. The two ‘are readily distinguished, when alive, by their differently coloured flowers and their differently shaped leaves. As seen in dried specimens, however, they are not always easily dis- criminated, and when Linnaeus enumerated both in 1753 he regarded them as varieties of one species. Ten years later Linnaeus recognised the species now described as distinct, and this judgment has never since been chal- lenged. M. edule and M. acinaciforme, together with the somewhat similar M. aequilaterale which, however, is confined to the Pacific coasts of America and to Australia, but does not occur in §. Africa, were grouped by Haworth in the section Acinaciformia, which, as Marloth points out, differs from all other sections of the genus in bearing fleshy fruits—in the S. African species known as Zuurvygen or Hottentot figs—with numerous small seeds embedded in a subacid edible pulp; in other sections the fruits are dry capsules. The cultural history of M. edule began long before it received that name. In 1732 it was, as a figure by Dillenius shows, in the garden of Sherard at Eltham. Moreover it was, as Dillenius knew, in the Breynian collection ; Breyn tells us it was in his garden in Holland in 1668. Description.—Herb, succulent, much branched, prostrate or pendulous, 2-4 ft. long, with rather stout angular branches. Leaves opposite, sessile, oblong, rather blunt, more or less 3-gonous, somewhat incurved, thickly fleshy, green, 17-3 in. long, over} in. wide. Flowers terminal, solitary, about 8 in. across, yellow when they open, changing later to flesh-coloured.

The species now figured, Rhododendron oreotrephes, 18 & native of Yunnan, where it was discovered by Mr. G. Forrest on the eastern flank of the Li-Kiang range at altitudes of 11,000-12,000 feet, growing in company with several other species of Rhododendron, and forming a tree fifteen to twenty-five feet high. The material for our plate has been received from Mr. J. C. Williams, in whose collection at Caerhays Castle, Cornwall, it thrives remarkably well, and where, Mr. Williams informs us, it is easy to grow if given a fairly exposed situation. It bears exposure to the sun at Caerhays better than most Rhododendrons, but Mr. Williams has found individual plants die very suddenly from no evident cause, and has experienced this more frequently with &. oreotrephes Ocroper-DEceMBER, 1918. than with other species of the genus. At Kew the species is evidently perfectly hardy. It passed through the winter of 1916-17, notwithstanding the severity of the conditions to which it was exposed, with as little injury as any Chinese Rhododendron. At Caerhays Mr. Williams finds that the flowers have a considerable range of colour, the shades varying a good deal in value; the form of the blossom varies also in individual plants. At Kew it flowers freely, and produces seed from which young plants have been raised. The most striking feature of R. orevtrephes is, however, the beauty of the foliage, due to the bloom on the underside of the leaves. In Cornwall, Mr. Williams remarks, the foliage of many of his plants is, at a particular stage of growth, among the most brilliant of any plant seen in the south-west of England, recalling the colour of the leaves of the sea- hollies. In the neighbourhood of London this character is far less striking. As yet none of the plants in cultivation have attained the dimensions noted by Mr. Forrest for the wild plant in China. In situations otherwise suitable it is best planted on a slope, so that the glaucous hue of its young leaves may be seen from below. Asa practical point, Mr. Williams observes that rabbits eat this Rhododendron more than they do most shrubs. Descriprion.— Shrub or, in the wild state, a tree up to 25 ft. high; new shoots sparingly beset with peltate glands, in their second year shining, glabrous and brownish.

A. Ro.re. Bulbophyllum Hamelinii was first found in Madagascar a quarter of a century ago. Living plants were sent by Mr. Hamelin to Messrs. Sander and Sons, St. Albans, and in 1893 a note in “Garden and Forest” (p. 336) detailed the leading features of the species—its large size, its curious pseudobulbs “ like some great flat marine shell,” its erect scape “thick as one’s finger” and a foot and a half long, and the large number of flower-scars along the upper portion of the scape. When that note was written the flowers had not been seen, and it was not until August, 1902, that a plant acquired by the Royal Botanic Garden, Glasnevin, produced an inflores- cence which enabled a description of the flowers to be prepared. The note from Sir F. W. Moore which accom- panied this inflorescence indicated that the plant hardly OcropeR-DECEMBER, 1918. _ fulfilled the expectations its size had led growers to form. This note refers to the disagreeable odour characteristic of this interesting plant, which is not closely allied to any other known Bulbophyllum, and is readily distin- guished from all the cultivated species by its obcordate- orbicular, compressed pseudobulbs, concave on one face, convex on the other, and closely flattened against the thick climbing rootstock. The Glasnevin plant of B. Hamelinii blossomed again in 1904. Another plant, obtained for Kew from Messrs. Sander, flowered for the first time in August, 1916, when our plate was prepared. In August, 1917, a third plant, part of the collection of the late Sir Trevor Lawrence, presented to Kew by Lady Lawrence in 1914, also flowered for the first time. Both Kew plants thrive well in a tropical house in baskets of peat and sphagnum suspended from the roof. They require abundant water whilst making their growth in autumn. Though &. Hamelinii has no near allies it resembles in its carrion-like odour the Bornean /. Beccarii, Reichb. f., figured at t. 6567 of this work. When the original consignment of B. [amelinii reached this country, no precise habitat was recorded, but a fruiting specimen collected by Mr. Warpur, which reached Kew in 1900, is noted as being from a forest at Tanabe. Description.—Herb, large, epiphytic; rootstock short, stout, woody ; pseudobulbs sessile, clustered, obcordate-orbicular, much compressed, 3-4 in. across, clothed at the base with ovate, acute, imbricate sheaths ; 2-foliate.
