The material originally sent home consisted of some pinnae and a few seeds and proved too incomplete for description. Two years later he made the first attempt to introduce the plant to European cultivation, but the stem which he sent home January, 1915. \ in 1870 unfortunately did not survive the journey. Later in the same year Kew received from Sir John a supply of seeds and some of these germinated, one of the plants of this introduction being in the Kew collection in 1881, growing alongside a fine male stem which was successfully transported to this country in 1878. In 1884 Sir John Kirk was again able to transmit a male and also a female stem, both of which have thriven well under the conditions suitable for other tropical Cycads in the Palm House at Kew, where they are still in vigorous health and growth. From these have been obtained the material from which the two plates here given have been prepared. In the meantime, however, the distinguished traveller Mr. J. M. Hildebrandt had also met with the species on the East African Coast over against the island of Zanzibar, and at other points on the same coast as far north as Mombasa. From the material obtained by him it was described, as Encephalartos Hildebrandtii, by Professor Braun and Mr. Bouché in 1874, and between 1874 and - 1876 Hildebrandt secured and transmitted to various European gardens a large number of stems. Relying on the appearance of some of these, the late Professor Regel in 1876 suggested that the East African plant might prove to be no more than a local form of the Natal species, L. villosus, Lem., of which an account has been given at t. 6654 of this work. The controversy thus raised was taken up by Braun who pointed out the differences between the two species, and in 1880 Pro- fessor Kichler confirmed Braun’s observations and even suggested that the difference in the shape of the female cone-scales justified the location of the two in distinct sections. In 1890 Professor Hennings, however, on the strength of a female specimen grown in a nursery at Schomberg, near Berlin, which showed characters that led him to consider it a connecting link between the Natal and the East African plant, reverted to the view expressed by Regel. The matter has again been very fully discussed by Dr. Stapf in the Kew Bulletin for 1914, and the conclusion to which he has come, that the view of Braun and Kichler is sound, while that of Regel and Hennings cannot be sustained, seems incontrovertible. The pinnae figured on t, 8592 are rather wider than is usual in this species. DeEscriptTion.— Tree with a cylindric stem, sometimes very short or at times up to 20 ft. in height, 1 ft. in diameter, closely beset with persistent imbricating leaf- bases.

The Cotoneaster which forms the subject of our figure was discovered in 1886 on limestone mountains in South- western Yunnan at altitudes of about 8,000 feet above sea-level by the late Abbé Delavay. Young plants were raised in 1888 from seeds sent by him to the Jardin des Plantes, Paris, whence, six years later, the plant from which material for our illustration has been prepared was sent to Kew. In collections C. pannosa is sometimes confused with C. Franchetii, Bois, to which it is closely allied. Both have the same marked elegance in growth and both are characterised by a thick tomentum on the young shoots, lower surface of the leaves, pedicels and calyx. But C. pannosa is readily distinguished from C. ranchetii by its smaller leaves with longer petioles, purer white and more spreading petals, and smaller fruits of a duller deeper red. In the fruiting spray depicted on our plate it will be observed that the majority of the fruits JANUARY, 1915, are oval, only those towards the ends of the branches being globose or nearly so. Sometimes, however, the proportion of globose to oval fruits is reversed, and taken generally, globose fruits outnumber those that are oval. Few shrubs are better adapted for a poor natural soil, such as that of Kew, than the Cotoneasters, and C. pan- nosa is no exception to this rule. It is perfectly hardy and thrives admirably in loam of good or even moderate quality. Propagation is easily effected by means of late summer cuttings in gentle heat or, more slowly, by the seed of which it produces such plentiful crops. This and - other species of the genus are to be recommended for gardens situated on calcareous formations. Description.—Shrub with deciduous foliage, about 8 ft. high, of lax graceful habit ; young branches slender, clothed at first with a pale brown tomentum, ultimately glabrous and dark purple on the side exposed to the sun.

The pleasing little Mesembryanthemum here for the first time described belongs to a group of species in that large genus characterised by each branch or division of the plant bearing at any one time but one pair of leaves which are united for the whole or for part of their extent into one mass, technically termed a “ corpusculum.” When a fresh pair of leaves, united in anew corpusculum, is being formed, the pair of the previous growth gradually shrivel to a papery consistence through which the new growth bursts. In the case of M. thecatum, depicted in the upper half of our plate, the two leaves of each suc- ceeding growth are united throughout and completely envelop the peduncle and ovary, leaving at their apex a mere fissure from which the actual flower protrudes. The species is one of the novelties discovered by Professor Pearson, Director of the National Botanic Garden of South Africa at Kirstenbosch near Cape Town, in the course of his very fruitful journey to the Orange River undertaken in 1910-11 under the auspices and with the JANUARY, 1915, assistance of the Percy Sladen Trust. It was met with growing on dry ridges south of Bakhuis in the Van Rhynsdorp Division of Cape Colony, and the plant from which our figure has been prepared formed part of a very valuable collection of succulents collected by Pro- fessor Pearson and his fellow-traveller on the expedition, Mr. N.S. Pillans, which was presented to Kew in 1911. It has thriven well and flowered freely under the con- ditions suitable for Mesembryanthemums generally. Its flowers open in the morning and close at night, and are devoid of scent; each flower lasts from four to six days. Description.—-//erb, small, stemless, succulent, tufted, glabrous. Leaves consolidated in obconic bodies, some- what convex-truncate at the tip, about 1} in. thick, bluish-green with dull green markings, central chink } in. long, concealing the peduncle and the ovary.

Brown, The interesting Mesembryanthemum which occupies the lower half of our plate is another of the fruits of the Percy Sladen Memorial Expedition to the Orange River, led in 1910-11 by Professor Pearson of Cape Town. Like its companion this species, J/. stylosum, is a hitherto uncharacterised one, belonging to the same natural group, though in this instance the welding of the two leaves forming each corpusculum is much less complete and the resultant bodies are deeply 2-lobed at the apex. J. stylosum was collected on the plains between Chubiessis and Stinkfontein in Little Namaqualand, and the plant from which our illustration has been prepared formed part of the same munificent accession to the succulent collection at Kew for which the institution is indebted to the Percy Sladen Trust and to the travellers who, thanks to their assistance, were enabled to investigate so thoroughly the vegetation of a considerable portion of western Cape Colony. The flowers in M. stylosum are bright yellow; they open in the day time and only in bright sunshine. They last for five to six days and are JANUARY, 1915. without odour. The species thrives well under the conditions suitable for fleshy-leaved Mesembryanthe- mums, of which there is at Kew a large collection. They are most successfully cultivated in a sunny greenhouse or frame, except during summer, when they are placed. in the open air. They enjoy a fair allowance of water at the root whilst in growth, but require little or none during winter when they are at rest.

The large Bromeliad here figured is a native of the forests in the provinces of Rio Janeiro and San Paulo in Southern Brazil and has been in cultivation in Europe for upwards of half a century. There are excellent figures of the plant published by Antoine from an example which flowered in the Hofburg Gardens at Vienna in 1874, while it has since then been figured several times, occasionally under synonyms other than the accepted name Tillandsia Regina, Vell. This variety of names has been due to the circumstance that the plant itself exhibits some degree of variation; its flowers may be white or yellow and sometimes change from the former to the latter colour during the flowering period. T. Regina has been in cultivation at Kew for many Frervary, 1915, : au years. Thirty years ago there was a large plant in the Victoria regia House, where it was grown in a pot over the lily tank. The plant from which the material for our figure has been derived was raised as an offset from the original plant and was about thirty years old when it flowered in the Mexican Section of the Temperate House, Kew, in May, 1912, dying down soon afterwards. It is of interest to note that in July, 1912, another plant of the same species flowered in the Royal Botanic Garden, Glasnevin. A sufficient supply of seeds has been matured so that it has been possible to raise a stock of young plants. 7. Regina belongs to the section Vriesia, which differs from Tillandsia proper in having scales at the base of the petals within. The only species with which it has been confused is 7. imperialis, C. H. Wright, which is readily distinguished by the flowers being secundly disposed on the branches. There is another species of the same section, even more closely allied to 7. Regina, which has been figured at t. 8192 of this work. The species in question, 7. Slokii, Hort., is however, easily recognised by its leaves with red blotches and its blood-red bracts. : Description.—Herb of large size, stemless.

The striking Orchid which forms the subject of our illustration belongs to the genus Mormodes, which is most nearly allied to Catasetwm, Rich., but differs there- from in its hermaphrodite flowers, and in the oblique twisting to one side of the lip, the margins of which are also sharply recurved so as to form a tube which rests upon the equally oblique apex of the column. The method of fertilisation was discussed by the late Mr. Darwin. The species was originally discovered in the forests of the Rio Negro and was described in 1877, from specimens collected there, by the late Mr. Barbosa Rodrigues. Some twelve years afterwards it was again met with in the Rio Negro district and was then introduced to cultivation by Messrs. Sander and Sons, St. Albans, in whose establishment a plant flowered in 1890. Ata later date it was introduced afresh, this time from the Frsruary, 1915. Amazon district, by Messrs. Hugh Low and Company. The plant from which our plate has been prepared is one which was purchased, when in flower, in February, 1914, for the Kew collection from Messrs. Sander. It formed part of a recent importation, once more from the Upper Amazon district, though the precise locality is not indicated, sent to St. Albans by Mr. Forget. The nearest ally of M. tigrinum is M. igneum, Lindl., a Peruvian species from which it is distinguished by its differently coloured flowers with a shorter lip. Both species thrive well in a tropical house under the conditions suitable for species of Catasetum.

HurcHinson. The pleasing Rhododendron here figured is a native of the mountains of Szechuan in Western China, where it occurs at altitudes of 6,000-10,000 feet above sea-level. It was first found in 1870, in the neighbourhood of Mou- pine, by the late Abbé David. It was again met with on Mount Omi and on neighbouring mountains by Mr. E. H. Wilson in 1908, and our figure has been prepared Fresrvuary, 1915. from a plant raised from Wilson’s seed of this last gathering, received at Kew from the Arnold Arboretum in the spring of 1909. The species was described from the Abbé David’s specimens by the late Mr. Franchet as f. moupinense. It is a very distinct plant readily recognised in the section with glandular leaves by the subverticelled somewhat cordate leaves, the large leafy calyx, the black-pilose twigs and petioles, the large white corollas spotted with red within the posterior side of the tube, and by the large conspicuous carmine anthers. The species is of sturdy dense habit, and as young plants speedily reach the flowering stage, blossom- ing for the first time when three or four years old and only a few inches in height, it is admirably adapted for the Rock Garden. According to Wilson it reaches a height of two to four feet and is usually found growing upon evergreen oaks and other broad-leaved trees. But in spite of its epiphytic character it appears to thrive very well in the sandy peat in which rhododendrons as a whole do so well. It has hitherto flowered in February and March, a date so early as to render the blossoms liable to injury by frost. DrscripTion.—Shrub, usually about 23 ft. high, in the wild state often epiphytic; branches leafy upwards, _ subterete, y'5-} in. thick, black-pilose, at length glabrous. Leaves somewhat verticillate, oblong-elliptic or ovate- elliptic, apex abruptly and bluntly mucronate, base rounded or subcordate, 3-12 in. long, 1-1 in. wide, firmly coriaceous, margin strongly recurved, usually ciliate, at length glabrous, above glabrous save for the sparingly puberulous midrib, slightly verrucose, beneath densely lepidote with yellow glands; midrib slightly narrowed from base to apex; lateral nerves usually 8, alternate, leaving the midrib at an angle of 45 degrees, slightly sunk above and faintly flexuous, beneath incon- spicuous; petioles stout, }-! in. long, usually densely black-pilose.

The member of the Myrtle family which is here de- picted is a species which was already figured in this work, at t. 473, more than a century ago. This species, Eugenia uniflora, is a native of Brazil and other parts of tropical America, but there are few tropical regions in which it is not cultivated, while in many it has become naturalised and established as a denizen in the vegetation. The specimen on which Linnaeus originally based_his diagnosis came as a matter of fact from India: This may help to account for the fact that when he had to deal with a specimen of the same plant from a country of which it is really a native the illustrious Swede re- named it Plinia pedunculata, under which synonym it was described in these pages in 1799. We have not, Freruary, 1915, however, taken the unusual course of supplying a second portrait of the same species owing to the fact that in the previous instance it was alluded to under an unnecessary name, but because in 1799 the fruit, which is not always to be met with in cultivated specimens, could not then be illustrated. The plant from which the material for our plate has been derived is one which was presented to Kew by the Director of the Jardin Colonial, Paris, under the name £. Michelii, Lamk. It has been grown in the great Palm House in a pot and has formed a much- branched shrub, some seven feet in height. There it fruited freely in May, 1914, and has enabled us to supple- ment the original plate. The fruits are edible. The specimen now figured, like that figured in 1799, is typical of the species, which, however, exhibits a certain degree of variation in the disposition of the flowers. DrscripTion.—Shrub or small tree; twigs terete and glabrous, internodes about as long as the leaves. Leaves opposite, ovate-elliptic, with an obtusely acuminate apex and a rounded base, up to 2} in. long and 1} in. broad; on the lower surface midrib, nerves, and smaller veins raised, on the upper midrib slightly impressed, but the nerves and smaller veins slightly raised; lateral nerves numerous on each side of the midrib, anastomos- ing towards the entire margin; lamina glabrous and punctate, supported by a petiole which is up to + in. long. lowers solitary, axillary, usually distant; peduncle terete, up to 14 in. long, glabrous.

The very striking Orchid of which a figure is here given was first imported to England from New Guinea by Messrs. Hugh Low and Company, Enfield, and at once attracted attention. Its long pendulous leaves with a glaucous upper surface suggested comparison with the genus Phalaenopsis, owing to the resemblance they bore to those of P. Schilleriana; at the same time the pseudobulbs indicated affinity with the genus Bulbophyllum. In May, 1914, a plant in the possession of Mr. E. V. Low, Vale Bridge Nursery, Hayward’s Heath, produced an inflorescence. This plant later became the property of the Rev. J. C. B. Fletcher, Mundham Vicarage, Colchester, by whom it was exhibited at a meeting of the Royal Horticultural Society under the name Bulbophyllum Fletcherianum. From a water colour sketch of the plant and a single flower presented to Kew Marca, 1915. by Mr. Fletcher, supplemented by the use of a living plant kindly lent for the purpose by Messrs. Stuart Low and Company, Jarvisbrook, Sussex, it has been possible to prepare the accompanying plate. The species is not a Bulbophyllum, if that name be employed in its proper and more restricted sense, but a Cirrhopetalum. Its affinity is not very clear, but it bears a rather remote resemblance to another New Guinea species, which has been figured at t. 7557 of this work as C’. robustum, Rolfe, which has, however, much smaller green leaves and much smaller flowers. The leaf in the background of our plate is a portrait of one of the leaves on Mr. Fletcher’s plant; the largest of the leaves on that plant, it may be added, was fourteen inches long. The smaller plant, shown entire on our plate, is that in the possession of Messrs. Stuart Low and Company. It has been propagated from a small side growth and as yet is far from being fully developed. The cultivation suitable for other species of Bulbophyllum and Cirrhopetalum has been found appropriate for this species. Description.—J//erb of considerable size, epiphytic. Rootstock stout; pseudobulbs close-set, subglobose or quadrate, somewhat compressed, transversely wrinkled and streaked with purple lines, 3~21 in. across, 1-foliate.

The Choniastrum section of the genus Lthododendron includes a small and fairly compact group of seven species distinguished from their congeners by the position of the flowers, which are produced from axillary buds crowded at the ends of the branches. This character is always associated with eglandular persistent leaves and long tubular funnel-shaped corollas; even the seed-pods in this group have a facies of their own. Within the Choniastrum group the subject of our illustration, Marca, 1915, Xt. stamineum, differs from its allies in having strikingly long, far-exserted stamens. A native of Western China, where it was met with by Mr. E. H. Wilson in 1900 when collecting on behalf of Messrs. J. Veitch and Sons, it affects particularly rocky shady ravines; although widely spread in that region, it is, according to Mr. Wilson, nowhere really common. For the material from which the accompanying plate has been prepared we are indebted to Mr. J. C. Williams, Caerhays Castle, Gorran, Cornwall, in whose renowned collection it flowered in April, 1914. The plant by which that material was provided grows, Mr. Williams informs us, on a steep hillside which faces east, but is well sheltered on all sides from the wind, with no shade save what is afforded by the contour of the locality, and fully exposed to whatever of sun its side of the hill receives. This plant, which was obtained by Mr. Williams from Messrs. Veitch in 1903 and is now nearly six feet in height and some five feet through near the ground, has borne stray flowers for three years and is now, in 1915, covered with bud. At Caerhays R. stamineum has been tried in other aspects, and the most vigorous individual plant in the collection there is in partial shade on a hillside which faces rather to the north of east. But while this example of /. stamineum forms a beautiful evergreen with a fine black-green foliage and young growths of a charming bronze colour, it has not yet, although thirteen years old, produced any flowers. Mr. Williams remarks ‘that in his experience the sun kills more plants at Caerhays than does the frost, though the wind is always the worst enemy, and that if only the wind can be kept out, a hillside which faces east or north-east is preferable for most of the Rhododendrons. From the experience in other collections it would appear that R. stamineum is not an easy plant to keep in vigorous health or to flower freely. When success attends the effort, the pains expended are well recompensed whether for the charm of the form or the fragrance of the flowers. At Caerhays it is propagated by means of layering.

The interesting Butterwort here figured is a native of Mexico, where it was first discovered by Dr. Purpus in 1910 growing on wet gypsum rocks at Minas de San Rafael in the State of San Luis Potosi. The plant from which our plate has been prepared was purchased in 1912 from Mr. R. Graessner of Perleberg. Besides being of pleasing aspect Pinguicula gypsicola 1s remarkable on account of the heteromorphy of its leaves. Those present at the time of flowering are, as depicted in our main-figure, long-linear with widened base and, when young, involute tips, and are two inches or so in length. When flowering is over these long leaves gradually die off centripetally, while in the crown a rosette is formed, Marcu, 1915. the leaves of which resemble those of some species of Sempervivum. When finally the linear leaves have wholly disappeared there is left only a compact rosette, some three-quarters of an inch through, such as is shown in fig. 5 of our plate, composed of winter-leaves one-third of an inch long. After persisting for a time these winter- Tosettes behave exactly like the summer ones ; their com- ponent leaves gradually die off centripetally while a new long-leaved flowering rosette gradually forms. So different in appearance are these rosettes that when seen apart no connection between them is suggested. The hairs of the summer-leaves are all many-celled and gland-tipped ; those of the winter-leaves vary, the cilia from the base upwards to near the tip being unicellular and eglandular, while at the tip the indumentum consists of many-celled hairs ending in minute glands. The transition from the summer- to the winter-rosette is fairly abrupt, and is well indicated in fig. 7 of our plate. Still more abrupt, however, is the passage from the winter- to the summer- rosette. Summer-rosettes, before passing into the winter- stage branch, though rather sparingly; these branches develop into daughter-rosettes of the winter-stage which may be detached and thus afford a means of propagation. The plant apparently does not depend entirely upon a gypsum substratum; at Kew it has thriven well and flowered freely in July, when grown in sphagnum moss kept saturated with water. Like many other species of Pinquicula, P. gypsicola has shown considerable variation in the size of the flower. At Kew the corolla-lobes have been nearly half-an-inch long ; in the specimens described by Mr. Brandegee the corolla-lobes were about half that length. At Kew it has been found possible to raise hybrids between P. gypsicola and P. caudata, Schlecht., another Mexican species. Descriprion.—Herb, when in flower 35 in. high, Leaves many, heteromorphous ; summer-leaves, when the plant is in flower, linear from a rather wider lanceolate base, 2-2} in. long, and at their origin about } in. wide, with revolute margins, pale green, clothed throughout the upper surface with viscid-glandular hairs; winter- leaves clustcred in a very dense rosette about 2 in. across, resembling that of a house-leek, each leaf spathulate- oblong, obtuse, } in. long, about 1-4 in. wide, flat above, bluntly keeled behind, margin ciliate but not glandular, elsewhere glabrous except for the glandular-ciliate tip.

The subgenus Pedrosia, Brand, is readily distinguished from the rest of the genus Lotus, Linn., by the presence of a distinct tooth below the apex of the style. The distribution of the subgenus is circumscribed ; that of the species L. campylocladus, a form of which is here figured, is of the “ Atlantic” type, for it is confined to the Atlantic Islands, the Iberian Peninsula and Morocco. Marcu, 1915. The specimens on which Z. campylocladus was originally based were gathered near Guimar in Tenerife, and differ from the form of the species now depicted in the smaller, more obovate leaflets and the shorter subappressed indu- mentum. The form villosior, here described, was originally met with by the late Mr. P. Barker Webb at Fuencaliente in the south of Palma, and was identified by him as L. arenarius, Brot., though with an indication that he had long felt a doubt as to whether the Tenerife and the Palma plants should not be treated as varieties of one species. Specimens which have since been gathered at Guimar and elsewhere in Tenerife have shown how well- founded was the doubt thus expressed; it is found that these specimens form a connecting series within which it is impossible to distinguish even varieties. At the same time L. campylocladus is undoubtedly closely allied to L. arenarius, within which the form now figured was included by Webb; the best distinguishing mark is to be found in the more or less cuneate leaflets, retuse or subtruncate at the apex, which characterise the former. The form here termed villosior is widely distributed both in Tenerife and in Palma. In the latter island it was met with by Mr. Sprague and Mr. Hutchinson in the Gran Caldera in 1913. The plant from which our figure has been made was raised at Kew from seeds presented by Dr. G. V. Perez of Orotava. It is possible that the seed came in the first instance from Tenerife, for it appears that Dr. Perez received it under the name LL. mascaensis, Burchard, a species known only from Tenerife. At Kew the species has been tried out of doors but does not give promise of being hardy. When grown in a frame it forms a plant about a foot in height, compact in habit and pleasing both in its flowers and in its silvery foliage. Description.—//erb ; root woody, branching from the base, with branching ascending stems woody below and shortly rather densely clothed with spreading hairs, as are the leaves and the calyces; internodes in cultivated plants }—1 in. long, in wild specimens up to 2 in. long.

Gibsonii, was based are in the national collection at the British Museum, Cromwell Road, where they were received from a locality on the equator, approximately 36° 70’ east of the meridian of Greenwich, at an elevation of about 8000 feet above sea-level. Both as regards the corolla and bracteoles these original specimens, which consist of Aprit, 1915, flowers only, are rather larger than is the case in the plant from which our figure has been prepared, but there is no other difference discernible. The plant figured, which flowered at Kew in June, 1914, was acquired by purchase from Messrs. Thompson and Charman, Nursery- men, Bushey, according to whom it had been obtained from British East Africa from a locality 6000 feet above sea-level, The introduction appears to have been effected by Mr. W. van der Weyer, Corfe Castle, Dorset, by whom it was shown at an exhibition of the Royal Horticultural Society in May,1913. The limb of the corolla is of a deep orange colour and waxy consistence, and the species is thereby readily distinguished from its nearest ally in the genus, the well-known 7. alata, Boj., also originally a native of Tropical Africa, though now naturalised in some parts of South-eastern Asia, long ago figured at t. 2591 of this work. In habit a perennial, 7. Gibsonii when grown in a pot under ordinary greenhouse con- ditions quickly develops leafy shoots which flower freely in summer. 3 Description.—Herb, perennial, twining, 4-5 ft. high; stems terete, beset with long spreading or slightlyrecurved hairs.

Wilson’s expedition of 1903-4, on behalf of Messrs. J. Veitch and Sons, the plant from which our illustration has been taken being one raised by them at Coombe Wood and acquired from them for Kew in 1908. During his later expeditions in China, Wilson again met with the species on several occasions. It is plentiful in the neighbourhood of Tachien-lu, in Western Szechuan. The nearest ally of R. Davidsonianum is, perhaps, R. ambiguum, Hemsl., another Chinese species figured at t. 8400 of this work. Aprin, 1915. It is most readily distinguished from the latter species by the more elegant habit, the smaller leaves, the differently coloured flowers and the more slender fila- ments. Like most of the Rhododendrons from China with scaly leaves, #. Davidsonianum gives promise of being very hardy. Its value as a garden plant will probably be similar to that of R. yunnanense, Franch., a Chinese species figured at t. 7614 of this work, and like that species it can be increased by means of late summer cuttings. Description.—Shrub, 34-10 ft. high ; branches divari- cate, terete, brown or greyish, glabrous; young twigs short, very finely puberulous or glabrous. Leaves lanceo- late or oblong-lanceolate, with a markedly mucronate tip, base obtuse or slightly rounded, 1-2} in. long, 1—3 in. wide, rigidly chartaceous, above at first sparingly black- dotted, at length glabrous and when dry strongly veined, beneath closely covered with small rounded glands; midrib flat above, inconspicuous, raised beneath, pale, gradually narrowed from base to tip, and prolonged into the long mucro; lateral nerves slightly visible above, arched, beneath hardly visible; petiole 1} in. long, sometimes faintly puberulous. Bud-scales suborbicular, slightly mucronate, coriaceous, densely ciliate, glabrous outside. lowers terminal, about 6-nate ; pedicels 1—2 in. long, covered with long rounded sessile glands. Calyx undulate, very short or nearly obsolete. Corolla pale rose, 1}-1? in. across, upper lip yellow-lepidote; tube about 4 in. long, slightly enlarged upwards, glabrous on both sides; lobes 5, oblong with rounded tips, about % in. long and } in. wide, finely striate.

The section Candelabra, which owes its name to the type of inflorescence, is one of the most natural in the genus Primula. Its members are natives of eastern and south-eastern Asia; all of them appear to inhabit moist meadows, all produce rosettes of leaves which recall those of the Primrose, and all produce tall scapes with superposed tiers of flowers. All further agree in having a rounded or shortly oblong capsule enclosed in a slightly accrescent calyx. Within the section the species assort themselves in two groups, that in which the flowers are Appin, 1915. purple, and that in which the flowers are yellow. In China, where the section has its headquarters, the number of species belonging to either group cannot yet be safely estimated; of those in cultivation the best known members of the group with yellow flowers are P. Cock- burnana, Hemsl., P. Bulleyana, Forrest, and P. serrati- folia, Franch. ; the most familiar among those with purple flowers are P. Beesiana, Forrest, P. Poissoni, Franch., and P. pulverulenta, Duthie.. The known species with yellow flowers which occur outside China are P. imperialis, Jungh., a native of Java which has the further interest attaching to most southern Asiatic species of the genus ; P. prolifera, Wall., which occurs in the Khasia Hills, east of the Brahmaputra valley; and P. Smithiana, Craib, a native of Sikkim in the Eastern Himalaya. The extra- Chinese species with purple flowers so far known are P. japonica, A. Gray, which is restricted to J apan; and the subject of our illustration, P. Miyabeana, which is endemic in Formosa, and is readily distinguished from all the other known members of the section Candelabra in having the calyx farinose within. The plant figured is one which was raised from seed received at Kew in 1913 from Mr. W. R. Price, who met with the species on Mount Morrison in Formosa, growing at an elevation of 7000 feet above sea-level. The plant has been cultivated at Kew in a frame, where it flowered in May, 1914, and ripened its seeds in July. It may prove to be hardy, at least in the warmer districts of the British Islands. It will probably be best to treat it as a biennial under the conditions given to its near ally P. Poissoni, figured at t. 7216 of this work, like which it behaves under culti- vation. A marked feature of the members of the section Candelabra is the readiness with which several of them lend themselves to hybridisation. Descriprion.—//erb, under cultivation apparently biennial. Leaves oblong-obovate or wide oblanceolate, when young acute, later obtuse or rounded, somewhat narrowed at the base, up to 8 in. long, from 14-2 in. wide, somewhat firmly papery, glabrous on both surfaces, beneath at first somewhat mealy, at length nearly or quite efarinose ; lateral nerves about 10 on each side, the lowest decidedly oblique, all visible above and raised beneath, with rather few transverse veins hardly visible above, but slightly raised beneath; margin irregularly denticulate except at the entire base, at first somewhat sparingly ciliolate, soon glabrous. Scape single, much longer than the leaves, up to 2 ft. in height, bearing several 6—10-flowered superposed whorls, at first sparingly mealy near the top, soon quite efarinose throughout ; bracts 4-3 in. long; pedicels up to 1} in. long, at first sparingly mealy, soon efarinose.

The Araliad here figured was originally described by Professor Oliver from specimens discovered by Professor A. Henry in the province of Hupeh in Central China about 1886. It was met with again in the same region by Mr. E. H. Wilson in 1901, and through his agency was introduced to cultivation by Messrs. J. Veitch and Sons. The plant which has supplied the material for our illustration is one at Kew which was purchased from Messrs. Veitch in 1913. When first described the species was referred with justice to the genus Lleutherococcus, based by the late Mr. Maximowicz on a species from Apri, 1915. Manchuria. More recently, however, Dr. Harms has proved satisfactorily that this genus is not in reality separable from the older genus Acanthopanaz.. Ingardens , A. leucorrhizum, here depicted, has been confused with A, Simonii, C. K. Schneid.; the figure which was pub- lished in the Gardeners’ Chronicle on 9 December, 1905 (fig. 152), under the name Eleutherococcus leucorrhizus is not the plant now described, but is really A. Simoni. The plant there referred to is well distinguished from the true A. leucorrhizum by its much stouter hooked spines distributed irregularly on the branchlets and by the numerous bristles on both surfaces of the leaflets. Another species very closely allied to the subject. of our plate is A, Henryi, Harms, already described at t. 8316 of this work, which differs from A. leucorrhizum in having shorter, stouter spines, shorter pubescent pedicels and pubescent leaves. The bark of the roots of A. leucorrhizum, from the appearance of which the specific name has been derived, is stated by Henry to be used by the Chinese as a drug, known to them as the White “ Wu Chia P’i.” As a shrub for gardens, A. leucorrhizum will be valued chiefly for its handsome foliage, of a type uncommon among hardy shrubs, and for its striking umbels of purple-black berries which are produced very abundantly and remain on the bushes late into the autumn. It has withstood perfectly the frosts experienced since its introduction, and although these have not provided the hardest tests of our climate we may reasonably assume it to be hardy. It thrives in well-drained sandy loam and is easily propagated by seeds. Duscription.—Shrub, 6-10 ft. high, everywhere glab- rous ; branchlets very pithy, sprinkled with pale lenticels, armed at the nodes with 1-6 pale, decurved spines 1—8 in. long, sharply pointed and subulate; internodes at times with a few similar but scattered spines. Leaves deciduous, alternate, usually 5-foliolate, sometimes 3- foliolate ; leaflets lanceolate or oblanceolate, apex acumi- nate, base acute, margin sharply doubly serrate, 2-5 in. long, 3-1} in. wide, their petiolules }-2 in. long; petioles 13-4 in. long, occasionally armed with one or two prickles, especially where the petiolules are attached.

The /ris here figured was discovered by Professor J. K. Urumov at Eski Dzumaja in Bulgaria in 1901. In his monograph it was referred by Mr. W. R. Dykes to J. Sin- tenisti, Janka, but, on raising plants from seeds obtained from Messrs. Vilmorin, Mr. Dykes recognised it as distinct. This decision has been confirmed by a plant received by the Hon. N. C. Rothschild from the original locality in Bulgaria. The difficulty experienced has been due to the original description. Dr. Velenovsky has described the plant as having green leaves and greenish spathes, but these organs, as Mr. Dykes points out, are glaucous, this colour being enhanced by the fairly large white asperities on the nerves. The dimensions here given have been Apri, 1915. derived from the specimen, sent by Mr. Dykes, which has served for our plate. But the stems may attain a height of 6-10 inches, while the leaves may be 18 inches long and a quarter of an inch wide, and the spathes may be over 4 inches in length. On the other hand Velenovsky’s plants had leaves one-twelfth of an inch across or under, while according to him the falls may measure as much as an inch and a half in length by an eighth to a sixth of an inch in width. Mr. Dykes finds that this species is as easy to grow in his garden at Godalming as the well- known J. graminea. It loses its foliage in the autumn, and it is not until the end of January that the glaucous tips of the leaves appear. It is not fastidious as to soil and has done well in sand enriched with leaf mould and chalk, but Mr. Dykes believes that it might grow even better in a stiffer loam overlying chalk. It should be moved, if necessary, either immediately the flowers are over or when growth becomes active in Spring, but not in the autumn when the plant is dormant. Descriprion.—Ilerb, rootstock brown, oblique, hardly as thick asa little finger. Stems several, 4—5 in, high, from almost to quite enveloped by the leaves, their bases sur- rounded by the dry remains of the old foliage. Leaves 5-6 to a stem, at flowering time barely reaching the blossoms, thereafter elongating and at length 10 in. long, 1—1 in. wide, linear, acute or very acute, glaucous, Jaxly nerved, the nerves rough with rather large white papillae.

The Alpinia here figured was first described as A. mutica in 1810 by Roxburgh, who had obtained it from Penang, then known as Prince of Wales’ Island, and cultivated it in the Hon. East India Company’s Botanic Garden at Calcutta, where it flowered during the greater part of the year, though most profusely during the hot weather. Its introduction to European cultivation must have been almost simultaneous with its advent to India, for in 1812 Salisbury mentioned it as having then “flowered for three years successively in the stove of the Comtesse de Vandes at Bayswater.” In 1828 Roscoe referred to it as flowering regularly in August in the Liverpool Botanic Garden. At a later date it became rare in British collections, and seems eventually to have dis- appeared from cultivation, though the name survived and became erroneously associated with more than one Aveust, 1915, of the congeners of our species. The one to which the — name is at present more usually misapplied is that described as A. mutica at t. 6908 of this work, which, however, differs from the true A. mutica here depicted in having much stouter flower-buds, and in possessing a labellum which is not distinctly 3-lobed. For the detec- tion of the error which has crept into horticultural lists, and for the successful reintroduction of the true plant we are indebted to Mr. H. N. Ridley, by whom, while he was still Director of the Botanic Garden at Singapore, the plant from which our figure has been prepared was transmitted to Kew. Grown in a tropical house under the conditions most suitable for species of Hedychium and for other species of Alpinia, such as A. nutans which was figured at t. 1903 of this work, it has thriven well, flowering for the first time in July, 1914, along with the species which in English collections has for a quarter of a century usurped its name, and enabling the difference between the two plants to be objectively appreciated. What the spurious A. mutica figured in our pages in 1889 may be is still a matter of some debate. Mr. Ridley has regarded it as identical with A. assimilis, Ridl., a Species described by him in 1899, but the late Dr. Schumann has treated it as a form of A. malaccensis, Roscoe, a figure of which is to be found in the Botanical Register at t. 328. It may be incidentally mentioned that at one time Dr. Schumann himself applied the name A, mutica to yet another species from Borneo, which he subsequently recognised as specifically distinct under the _ name A. Korthalsii, K. Schum. The nearest affinity of the true A. mutica, Roxb., is, as Mr. Wright has indicated, with A, calcarata, Roscoe. The two species are, however, very readily distinguished by their differently shaped labellum, which in A. mutica has two basal hirsute glands instead of the spurs met with in that of A. calcarata. Descriprion.— Herb, perennial, stems 6-8 ft. high. Leaves linear-lanceolate, acuminate, 1—2 ft. long, 1-24 in. wide, glabrous save for the ciliate edges; petiole $ in. long, channelled above; ligule short, erose ; sheath reaching 9 in. in length.

HuTcHInson. The beautiful Rhododendron now figured is a native of the neighbourhood of Ta-chien-lu in Western Szechuan, where it occurs rather abundantly in upland thickets and woods at about 12,000 feet above sea-level. The plant from which the material for our plate has been derived was raised from seed collected in 1908 by Mr. E. H. Wilson when travelling in China on behalf of Professor Sargent, Arnold Arboretum, by whom a supply was presented to Kew in 1909. There was, however, @ previous introduction of this species, also by means of seed obtained by Mr. Wilson, but on behalf of Messrs. J. Veitch and Sons. The species has reached the stage of Aveust, 1915. flowering after an unusually brief period, for some of the plants raised in 1909 produced blossoms in 1913. Cer- tainly one of the most distinct of the new Chinese Rhododendrons, #. Souliei falls within that group of the section Lurhododendron in which the leaves are glabrous and have no glands. Within this group it may be at once recognised by its long-petioled wide-based leaves, its well-defined calyx-lobes edged with red glands, and its flat saucer-shaped flowers. At Kew it has thriven well in a semi-shaded position and is of low, bushy habit. Drscription.—Shrul ; branches stout, glabrous; young twigs terete, purplish-pink, beset with red-stalked glands.

Skan, : The Manchurian Hazel belongs to a group in which the involucre is prolonged beyond the nut into a tube sometimes measuring 1} in. long, and is covered, particu- larly in the lower part, with yellowish bristly hairs. Its affinities with the Eastern North American C. rostrata, Ait., are so evident that it is not always easy to distin- guish it. In C. mandshurica, however, the leaves are usually broader and are often more or less deeply lobed Avueust, 1915, in the upper part, though in the specimens from the Kew plant the lobing is not pronounced; the young shoots are generally furnished with a more abundant soft pubescence, and the petioles as a rule are longer. C. rostrata, var. californica, A.DC. (C. californica, Rose), closely resembles C. mandshurica in its leaves which are, however, less markedly lobed ; moreover, it has glandular- hispid young shoots, a shorter involucre and a thicker nut-shell, C. mandshurica, var. Fargesii, Burkill, from Szechuan, differs from the type in having narrowly ovate leaves apparently not cordate at the base. C. Siebul- diana, Blume (C. rostrata, var. Sieboldiana, Maxim.), a Japanese plant, has a much shorter tube to the involucre and differs also in leaf characters. C. mandshurica is common in mountainous districts in Eastern Manchuria, and forms dense thickets in shady and dry woods. It was first collected by Maximowicz near to the Amur River in 1855. It is also recorded from Corea, from the provinces of Shingking and Chihli in Northern China, and from Yesso and N ippon in Japan. Its introduction to Kew dates from 1882 when nuts were received from the late Dr. E. Bretschneider ; ten years later the plant was received from Prof. Sargent of the Arnold Arboretum, and again in 1906. The material for the figure was furnished by one of the plants raised at Kew from the seed received from Dr. Bret- schneider. It is a bush about five fect high and is certainly very hardy. Though it has occasionally pro- duced nuts it did not bear its remarkable fruits in great quantity until 1912. That year, owing, it is assumed, to the great heat of the summer of 1911, and the consequent thorough ripening of the wood, it bore an abundant crop. It thrives in loamy soil and can be increased by layers. fe en, attaining a height of 15 ft. in be wild state, young twigs puberulous or sparingly airy, at length becoming glabrous. Leaves suborbicular, elliptic or ovate, 23-6 in. long, usually 3-4 in. wide, irregularly double-serrate, apex acuminate to almost 3 often more or less deeply incised-lobed beyond . middle, base slightly cordate, sparingly pubescent Move, Sometimes rather densely softly pubescent, especi- ally on the nerves, beneath; petiole 1~1} in., but usually about 4% in. long; stipules elliptic or ovate, acute or acuminate, under +} in. long, about } in. wide, entire or occasionally with a few teeth. Male catkins solitary or in twos or threes; scales deltoid, cuspidate, hirsute. Jruits in clusters of 2-6, often accompanied by abortive ones. /nvolucre closely enveloping the nut, produced upwards in a tube, densely clothed, especially in the lower half, with setose-hispid yellowish-brown hairs ; tube 1-1} in. long, cylindric or somewhat widened at the base, slightly many-striate ; mouth oblique, more or less laciniate.

Hurcuinson. The Senecio which forms the subject of our illustration is a native of South Africa, where it is known to occur throughout the coast region from the district of Rivers- dale as far as Algoa Bay. There are one or two earlier but doubtful records which connect the species with the Table Mountain region, but there is no definite proof of its presence there now. The late Dr. Harvey included S. glastifolius in the group of species of a shrubby or almost shrubby character which he designated the figidi. At the same time there is no doubt that it is extremely closely allied to another species from the same general region, S. multibracteatus, Harv., which has been referred by its author to the group Annuwi recognised by him. From S. glastifolius it is very easy to distinguish S. multibracteatus owing to the scabrid leaves and more Aveustr, 1915. copiously bracteate peduncles of the latter plant. Herbarium material of S. glastifolius shows that there is considerable variation in the shape, texture and toothing of the leaves. These changes of appearance, waich may be due to the conditions under which the plants have grown, leave the flower-heads remarkably uniform and unmistakable on account of the numerous exterior supple- mentary bracts. From a remark in the note which accompanies a full-page illustration of the species in the Gardeners’ Chronicle for 1910, it would appear that S. glastifolius was raised by Messrs. Sutton and Sons from seeds received by them from the district of George, immediately to the east of Riversdale. The plant from which the figure here given has been prepared was pre- sented to Kew in 1913 by Mr. H. Rabjohn, Twickel, Delden, Holland, and flowered in a greenhouse in April, 1914, It is a perennial, is easily propagated by cuttings and grows into an elegant upright plant, about four fect in height, flowering during April and May. It does well if given conservatory treatment and grown along with greenhouse Cinerarias,. but it may be noted that Mr. ‘Rabjohn, in the Gardeners’ Chronicle, writing from Welbeck Abbey, Worksop, in 1910, has described it as being vigorous in an open border, resisting successfully ten degrees of frost, though succumbing when the thermometer fell to 15°. _Duscription.—ZHerb, perennial, slender, erect, 4 ft. high ; stem branching upwards, sulcate, green, glabrous.

Henry, who found it in the districts of Chienshih and Patung, Hupeh, in 1888, and noted that it was common on the mountains at 4000 to 6000 feet. It was afterwards collected at Tchenkeoutin in Szechuan by Farges, and in 1900 it was introduced into cultivation by Messrs. Veitch and Sons through Mr. E. H. Wilson, who being unable to introduce the tree by means of seeds, sent home a living plant. It is from this individual, which grew in the Coombe Wood nursery SEPTEMBER, 1915, until the sale of the collections there, that the specimens in collections in this country have been propagated. As regards size of leaf Populus lasiocarpa is undoubtedly the finest of all the poplars of which we have knowledge. Even a double plate of this work is insufficient to show the dimensions of its leaves in full; the blade not infrequently measures fourteen inches in length by nine inches in width and, whatever the measurement, is conspicuous for the rich red of the midrib and chief veins and petiole. In vegetative characters our tree resembles P. heterophylla, Linn., of the Eastern and South-eastern United States; its catkins, however, are very different, and its closest ally is doubtless P. glauca, Haines, from Tonglo in Sikkim; like this latter species it has polygamous flowers. The few flowering catkins seen were obtained from a cultivated plant, and may not be characteristic of the species. It should be mentioned, however, that P. glauca, so far as Mr. Haines has observed, produces in the wild state female or more frequently only hermaphrodite flowers; he found no male tree. The male catkins accompanying Henry’s specimens were picked up from the ground beneath a leafless tree in South Patung, and Prof. Oliver cautiously dealt with them as possibly not belonging to P. lasiocarpa. The flowers have much longer pedicels than those of the cultivated plant, and the disk is distinctly oblique. The anthers agree. Populus lasiocarpa flowered in 1914 in the gardens of Mr. F. C. Stern, Highdown, Goring-by- Sea, Sussex, and of Sir Harry Veitch, East Burnham Park, Slough, and the figure was prepared from material received from the former supplemented by catkins of more mature fruits from Sir Harry Veitch. The species thrives well on deep loam, and, like most poplars, enjoys abundant moisture at the root. Hitherto it has been propagated by grafting on stocks of the Black Poplar group, but it will eventually, no doubt, be found to succeed better on its own roots.

The Gladiolus here depicted was discovered by Mr. C. J. Meller in 1861 on the Manganja Hills, Nyasaland, during the Zambesi Expedition led by Dr. Livingstone. Since then G. Melleri has been found to occupy a considerable area in Eastern Tropical Africa, for it has been collected at various localities in British Central Africa, in Portuguese East Africa, in the Matabele country and in Mashonaland. The plant which has formed the subject of our plate flowered at Kew in October, 1913, the corm having been received in June from Mr. A. Hislop who had obtained it at Makoni Kop, Rusape, Rhodesia. The nearest ally of G. Melleri is G. Buchanani, Baker, another Nyasa- land species, in which, however, we find several well- developed leaves about as long as and produced along with the inflorescence, instead of only one rigid far- produced leaf with several much shorter sheathing leaves as in our plant. Grown in a greenhouse with other SepremMBer, 1915. species of Gladiolus, G. Melleri thrives well, and in facies affords an interesting contrast with most of them.

The genus Ornithoboea was originally based on a solitary species from Tenasserim, sent to the late Sir William Hooker by the Rev. C. P. Parish over half a century ago, though a description of Parish’s genus was not pub- lished until 1883, when Mr. C. B. Clarke named the species O. Parishii. Thirty years later Mr. Craib added two more species, 0. Henryi discovered by Mr. A. Henry in Yunnan, near the Burmese frontier, and 0. Lacei, sent by Mr. J. H. Lace from Upper Burma. Since 1913 Craib has described yet another, O. lanata, found by Dr. A. F. G. Kerr in North-western Siam. Another form sent from the same region by Kerr, which comes near QO. Lacei, has flowered in the Botanic Garden of Trinity College, Dublin; yet another, known only in fruit, occurs in Tonkin. The first record of this Indo-Chinese genus in cultivation relates to Kerr’s two Siamese forms, flowered at Dublin by Professor SEPTEMBER, 1915. Dixon; 0. lanata, sent by Kerr, has also flowered at Kew. The plant of O. Lacei now figured was raised at Kew from seed found in a capsule of the herbarium type of the species. Cultivated plants differ from the parent in having longer petioles and larger leaves. They flowered in June, 1914, in a warm greenhouse under the treatment suitable for tropical and subtropical Gesneriads, and matured good seed. In its twisted fruits Ornithoboea resembles Boca and Streptocarpus, but its capsules are shorter and stouter ; from both genera it is distinguished by the bilabiate corolla with short upper lip. Derscription.—Herb, apparently biennial; stem with the lower portion, produced during the first season, over 4 in. long, nearly } in. thick, more or less 4-angled, densely clothed during the second season with the per- sistent bases of the old petioles, rather closely hairy especially towards the top; upper flowering portion of the stem usually about 12 in. long, everywhere glandular- hairy.

POR AEE aE i] The very striking Metrosideros here figured is a native of New Zealand, in which country the genus is well represented, three of its members having already a place in our pages: M. florida, Sm., at t. 4471; M. tomentosa, A. Rich., at t. 4488; and JZ. buxifolia, A. Cunn., at t. 4515. In our earlier volumes, too, five other figures have been given of Australian plants then referred to Metrosideros: M. citrina, Curt., at t. 260; M. speciosa, Sims, at t. 1761; JZ. saligna, Sm., at t. 1821; M. hispida, —Sm., at’ t. 1960; and //. viridiflora, Sims, at t. 2602. But of these Australian species all with the exception M. hispida, which is Angophora cordifolia, Cav., have now been better transferred to the genus Callistemon. The species now illustrated, M. diffusa, is confined to the North Island of New Zealand, where it is not uncommon in forests from Mongonui and Ahipara to the south-east coast and Taranaki, occurring from sea-level to elevations of 2000 feet. For its introduction to this country horti- SepremBer, 1915. culture is indebted to Capt. A. A. Dorrien-Smith, who informs us that while it usually grows as a creeper and prefers to have its roots in the shade, it is in its native haunts very accommodating, as it also forms a fairly compact rigid shrub in the middle of lava-flows. Its usual and apparently natural habit, however, is that of a creeper on trunks of trees, when, like various species of Ficus, it forms more rigid spreading branches as it grows older. It is only on such branches, when they are mature, that flowers are borne. The material for our figure has been derived from a plant cultivated by Mr. T. A. Dorrien-Smith in his garden at Tresco Abbey, Scilly, where it has thriven well in a raised pocket against a south wall shaded from the midday sun, its roots attaching themselves to the stones like ivy. Under these congenial conditions it flowered for the first time from the spread- ing branches in April, 1914, doing so again, even more profusely, in 1915. Itis readily reproduced by cuttings struck under a bell glass in autumn, plants so raised flowering in their second or third season. It can also be raised from seed, but plants so obtained take many years to attain mature growth and produce flowers. It should be noted that this is not the plant figured as M. diffusa at t. 569 of the Icones Plantarum ; that fi t M. albiflora, Sol. at figure represents DeEscription.—Shrub, far climbing, divaricately branched, the twigs terete or faintly 4-angled, puberulous.

The handsome tree now figured belongs to that section of Pyrus which Roemer established as a separate genus, Eriolobus. To it belong also the Japanese P. T'schonosku, Maxim., figured at t. 8179 of this work, and P. trilohata, DC., a native of Syria, very rare in gardens but repre- sented in the Kew collection. riolobus differs from the Aria group, in which Franchet placed P. yunnanensis, by the styles being united for their lower third or more, and from Malus by the flesh of the fruit having grit-cells. The tree from which our figure was prepared is now growing in the collection of Pyrus immediately south of the Temperate House at Kew. It was purchased in 1913 from Messrs. Veitch, who raised it in 1900 in their Coombe Wood Nursery from seed sent from the district of Chang-yang in Western China by Mr. E. H. Wilson. A tree heavily laden with the handsome fruits was Ocroper, 1915. exhibited under the name P. Veitchi/, at the Horti- cultural Hall, Westminster, on Oct. 8, 1912, by Messrs. Veitch. P. yunnanensis was originally discovered by the Abbé Delavay in Yunnan, growing in mountain woods at 9000-10,000 feet elevation. From P. Tschonoskii, its nearest ally, it is distinguished by its smaller flowers, much more numerous in the corymb, the smaller red fruits, and the more deeply lobed leaves of the barren shoots. Dr. Schneider describes the calyx-lobes as falling from the apex of the fruit, and stress has been laid on this statement under t. 8179 of the present work, but none of the specimens in the Kew Collection exhibit this character. It promises to be perfectly hardy and its abundant seeds will make its increase easy. Planted in good deep loam it grows well and, more especially in autumn, makes an attractive feature in the garden. Description.—Tree, 20 to 30 ft. high, unarmed ; young shoots at first felted, becoming glabrous and reddish-brown. Leaves deciduous; ovate and finely and irregularly serrate on the flowering shoots, often more obovate and shallowly lobed as well as serrate on the barren shoots, acute at the apex, cordate or rounded at the base ; 2-43 in. long, 13-3 in. wide; primary veins six to nine; dull green and at first floccose, ulti- mately nearly glabrous above, covered with a pale brown felt beneath, much of which falls away by autumn; petiole {-1} in. long, pubescent. Flowers % in. wide, im racemose corymbs 2-2) in. in diameter, terminating short, felted twigs which carry three or four leaves; rachis and pedicels felted, the latter about 1 in. long.

The interesting Chinese Gentian now figured is a member of the section of the genus Gentiana distinguished by Professor Kusnezow as Aptera. According to the arrangement adopted by Kusnezow G. gracilipes should be placed nearest to G. dahurica, Fisch., with which except for its longer pedicels it agrees closely in its general facies; or alternatively next to G. Fetisowti, Maxim., with which it shares the character of a spathaceously divided calyx. For the material on which our plate of G. gracilipes is based we are indebted to the kindness of Mr. H. J. Elwes, in whose garden at Colesborne, Cheltenham, a plant which flowered there in August, 1914, was raised from seed collected in Kansu and received at Colesborne through the late Mr. R. Wood- ward. This plant, which was presented by Mr. Elwes to Kew, has proved quite hardy and thrives vigorously in a cool sheltered corner. It has not yet ripened seed, but OcropER, 1915. appears to be as easily managed as the other members of the section Aptera, of which several are already in cultivation. The chief distinctive feature of G. gracili- pes is the length of its slender pedicels, which arise singly in the axils of the uppermost leaves of the flowering shoot. The lateral position of the flowering shoot this species shares with G. dahurica; the spatha- ceous division of the calyx on one side it shares not only with G. Fetisowii, but with G. straminea, Maxim., and some other members of the section Aptera. At the same time this latter character is not universal in the section ; several of the species, in addition to G. dahurica, have a normally tubular calyx.

The genus Promenaea was founded by Lindley over seventy years ago on four small Brazilian species which had until then been included in Mazillaria, Ruiz et Pav., along with a fifth from British Guiana ; some other species have since then been described from Colombia. The late Professor Reichenbach subsequently included Promenaea, with other allied genera, in Zygopetalum, proposed by Sir William Hooker in 1827. In this Reichenbach was followed by Bentham and Hooker in 1883, though they accorded Promenaea the status of asection. Reichenbach, however, had already reconsidered his earlier conclusion, and Promenaea is now thought as entitled to generic rank as some other similar groups whose status has never been questioned. One species of this genus, P. graminea, Lindl., from Guiana, has been figured at t. 3877 of this work as Mavillaria stapelioides; the true P. stapelioides is, how- ever, a native of Brasil. The interesting little species now figured has a somewhat obscure history, for we are still without definite record of its native country. The OcroBER, 1915. plant is one in the Kew collection which thrives well in a tropical house under the conditions suitable for species of Mavillaria and Zygopetalum, and flowered there in June, 1914. It had been presented to the Gardens by the Dowager Lady Lawrence, earlier in the year, as part of the collection of the late Sir Trevor Lawrence, at Burford, Dorking, so rich in species previously unrepre- sented at Kew and rarely met with in cultivation. This species, P. microptera, was described in 1881 by Reichen- bach, whose material, which came originally from Mr. d’Haene of Ghent, had been sent by Mr. H. Veitch; a day later he received it also from Mr. B. S. Williams of Holloway. In 1890 material, probably from the original source, was communicated to Kew from the Royal Botanic Garden, Glasnevin, and there is little reason to doubt that the plant now figured had also formed part of the same importation, for the Burford label indicates that it reached Sir Trevor Lawrence from the collection of Mr. Williams. The nearest ally of P. microptera, as Professor Reichenbach and Mr. Rolfe point out, is a Brasilian species, P. anthina, Lindl.; this does not, by itself, entitle us to assume that P. microptera is also a native of Brasil rather than of Colombia or Guiana, though it suggests that possibility. Description.—Herb, epiphytic ; pseudobulbs clustered, ovoid, grooved, 4—} in. long, 2-foliate. Leaves lanceolate, acuminate, somewhat arcuate, plicate, pale green, 3-34 in. long, 3-3 in. wide.

TURRILL. The genus Streptocarpus is confined to Africa south of the Tropic of Cancer and to the Mascarenes. Two sections are generally recognized ; one, Unifoliatae, has only one green assimilating leaf which is a persistent cotyledon ; the other, Aosulatae, has 1-4 leaves in addition to the cotyledon which is usually present. The species figured is one of the Unifoliatae, of which about fifteen are already known from various parts of South Africa. The nearly or quite glabrous leaf (cotyledon) of S. denticulata is unlike the densely hairy one of S. pusilla, Harv., to which our plant appears most nearly allied. The glandular-pubescent character of the inflorescence is a noticeable feature, though our species shares this with some of the others. The general colour of the flowers is distinctive, and may be described as rose-purple with lines of deeper carmine on the lower lip, and dark- purple blotches on the lower part of the upper lip. In other species of Streptocarpus figured in this work the corolla is more or less blue or violet, as, in S. OcroBER, 1915, Galpini, Hook. f., at t. 7230; S. Wendlandii, Dammann, at t. 7447; and S. Mahoni, Hook. f., at t. 7857. The material for our plate has been derived from a plant presented to Kew by Mr. R. I. Lynch, Botanic Garden, Cambridge, in 1914, This plant was raised by Mr. Lynch from seed communicated by Mr. W. E. Ledger, Wimbledon, who had received it from South Africa, where it had been collected by Mr. J. N. Thorn- croft on one of the mountains near Barberton, in the Transvaal. It has thriven well under the conditions suitable for other species of the genus, and has ripened seeds from which a second generation of plants has been raised. Crosses, Mr. Lynch informs us, have been made between S. denticulata and various species, more especially S. cyaneus, 8. Moore, with which it seems to pair more readily than with others. In the case of S. cyaneus, Crosses have been made both ways, and in each the influence of the female parent has shown itself the stronger. Description.—Herb, stemless and with only one leaf, which is an enlarged persistent cotyledon.

The striking form of Clematis uncinata which is the subject of our plate differs from the plant originally described as C. wncinata by Champion, by its leafy inflorescence, that of the type being comparatively leafless, and by its leaflets being all retuse in place of acutely acuminate and recurved or almost hooked at the tip, the feature to which the species owes its name. Yet in spite of the distinctive appearance thus imparted to the present form, the two extremes are connected by a series of intermediate conditions, the existence of which renders it impossible to accord our plant even the rank of a variety. For the material from which our illustration has been prepared we are indebted to Captain D. V. Pirie, in whose garden at the Chateau de Varennes, a few miles west of Angers, it makes a most beautiful picture, clambering over a wall and succeeding under the strong sun of Western France much better than it does at Kew. Fragrant as well as graceful, C. uncinata is evidently a species which loves bright sunshine. In OcroBER, 1915. England it does not appear to be very hardy in the open ground and will probably require to be grown on a south wall in order to bring out its best qualities.

The Anemone here figured was collected by Mrs. Wheeler Cuffe at a high altitude on Mount Victoria, a peak 12,500 feet in height in the Arakan Yomah in Western Burma. Attempts, all of which had proved unsuccessful, had been made to send seeds to Europe but, during a visit which Mrs. Cuffe was able to pay to Mount Victoria in 1913, she was able to obtain plants which she brought home herself and presented to the Royal Botanic Gardens, Glasnevin. Here they throve well in a cold frame, where they have passed uninjured through two winters, flowering freely in May and June. From one of these plants, sent by Sir Frederick Moore for NovEMBER, 1915. the purpose, our plate has been prepared. The species, A. obtusilola, to which this interesting Burmese plant is here referred, was first described by Mr. D. Don in 1825 from specimens sent home by Dr. Wallich from Gossain Than in the Alps of Central N epal. Its range of distribu- tion, for an alpine species, is unusually wide, for it extends from Kashmir throughout the Himalaya to Western China, and its discovery on Mount Victoria Somewhat unexpectedly widens its area towards the south. As Sir Joseph Hooker has pointed out, A. obtusiloba is further extremely variable in size, hairiness and colour of flower; one singular form from Western Tibet with numerous golden yellow sepals is perfectly glabrous. Elsewhere the flowers may be white, purplish or golden, and in Kashmir, where both yellow and purple- flowered forms occur, the latter is well-known to English visitors as the Blue Buttercup. This name is also used in Burma where, so far, only a form with purplish-blue flowers has been found. The distinctive feature of this flowering branches, a feature not met with in specimens from other portions of the wide area in which A. obtusi- Himalayan ‘Specimens are concerned, is probably the result of differences in the conditions under which individual plants have been grown, and it is not incon- ceivable that the great length of the flowering branches and their decumbent position in the form now figured may be the consequences of cultivation. In the absence to treat this charming plant as a form of A. obtusiluba ; should the communication of material from its original habitat show that the features which mark it are natural ones, it may be desirable to treat it rather as a distinct variety. The plant gives some promise of proving hardy; an example planted out at Glasnevin in May, 1915, has grown as well and flowered as freely as those in the frame. Derscription.—//erh, perennial. Leaves at first erect, at length spreading and rosulate, more or less ovate, about 2 in. long and broad, 3-partite with each segment 3-fid, rather pale beneath, beset on both faces with long white hairs, the nerves raised beneath, slightly sunk above ; petiole 21—23 in. long, beset with long spreading white hairs except at the base where they are infolded and are pale and glabrous on the upper side.

The subject of our plate is one of the most attractive and, from the cultural standpoint, one of the most distinct of the various shrubby Potentillas added to our collections in recent years. It is a native of upland thickets in Szechuan and Western Hupeh at elevations of over 6000 feet above sea-level, and was introduced from this area by Messrs. J. Veitch and Sons through their collector, Mr. E. H. Wilson, in 1900. It flowered under cultivation for the first time in their nursery at Coombe Wood in 1902. In 1907 Mr. Wilson sent plants from the Arnold Arboretum on behalf of Professor Sargent, and in 1911 he treated the plant as a distinct species, P. Veitchii. In 1912 another plant raised from Novemper, 1915. Northern Chinese seed was received at Kew under the same name from the Arnold Arboretum. This flowered in the hardy collection here in 1914 and from it the material for our plate has been obtained. This plant differs from the one from Western Hupeh in having less hairy leaves with less prominent lateral veins, somewhat smaller outer sepals and petals, and a rather longer style more attenuated towards the base. In other respects the two plants agree. But while sufficiently distinct asa garden-plant, there is little doubt that the form here figured must be looked upon as one intermediate between P. fruticosa, Linn., and P. davurica, Nestl. Several such — forms with whitish or pale sulphur-coloured flowers are known from Eastern Siberia and Manchuria, where the areas of these two species overlap ; they appear to correspond with the different variations referred to the reputed garden hybrid, P. Friedrichseni, Spith. Our plant has indeed already been referred as a variety to P. fruticosa by Mr. Bean ‘in his excellent work on “ Trees and Shrubs Hardy in the British Isles,” and that it must be accorded treatment of this kind is indisputable. Perhaps, however, it is on the whole preferable to reduce it to the other species of the pair, P. davurica, a plant well known in cultivation and figured at t. 3676 of this work as P. glabra, Lodd., which has leaflets that, even in bud, are glabrous except for a few hairs along the Margins, and is in its native country a dwarf compact shrub. There are other distinct varieties of P. davurica ; one with a dense and shaggy tomentum from Manchuria has been distinguished under P. fruticosa, not under its proper species, as var. mandschurica, Maxim. ; another with silvery leaves occurs in Western China. . davuriea, var. Veitchii, in its native country affects open, rocky situations, fully exposed to the sun. Mr. Wilson describes it as being rem arkably floriferous ; though at its best in early summer, it flowers continuously from May till late autumn, producing its sprays of snow-white flowers well above the grey-green foliage. In cultivation it makes a shapely low bush and flowers continuously pate May until September. It likes a loamy soil and an n, sunny position, and may be propagated by cuttings made in July and August.

Roure. : The interesting Japanese Araliad now figured has long been known to European cultivators. It is the original Aralia japonica of Thunberg, but was separated from the genus Aralia by Decaisne and Planchon, when these authors revised the Araliaceae, because of its different floral structure. The name Fatsia, given by them to the newly established genus, was bestowed owing its being believed that the native name of our plant is Fatsi. It is not certain, however, that this is the case; according to Franchet and Savatier, the Japanese name is more correctly written Iats’de. These latter authors included in the genus a second species, F. horrida, which is, however, better referred to Echino- DreceMBER, 1915. panar, Dene & Planch., and has for this reason been figured as /. horridus at t. 8572 of this work. Another species was added to the genus by Bentham and Hooker as I’. papyrifera; this species, which has with justice been transferred by C. Koch to the genus Tetrapanax, has also found a place at t. 4697 of this work under its older name Aralia papyrifera, Hook. The plant now figured, which is thus the sole representative of its genus, though a common feature in collections for over sixty years, has chiefly been in use as a decorative plant in conservatories. It is, however, hardy in the average climate of Great Britain if it be given a sheltered situation. Plants put out in 189] have succeeded well in the Bamboo Garden at Kew, and although they suffered somewhat from the great frosts of February, 1895, they were not destroyed, and that has been the only occasion on which they appear to have been affected by cold. At the same time this shrub is to be seen at its very best in the gardens of our southern and western counties. Flowering, as it does, in late autumn, its huge panicles produce a particularly striking effect in October and _ November, when there are few other plants in blossom. If F. japonica can be afforded a position which is sheltered from the sun during the middle of the day, it does better than in more exposed situations. It likes a loamy soil, and is increased by placing cuttings of a fairly firm growth singly in pots plunged in a mildly heated pro- pagating frame. DESCRIPTION.—Shrub, 3-13 ft. high, unarmed; stem terete, without prickles, leafy. Leaves petioled, 7-9-lobed, 5-12 in. wide, glabrous; lobes elliptic-lanceolate or _ oblong, acuminate, serrate; petiole 4-12 in. long, base _ expanded and at times sheathing.

A, SPRAGUE. ; The Spindle-tree which we figure here is one which appears to be common in Japan and extends into Corea without, however, occurring in China. It has very much the appearance of the European Luonymus latifolius, Scop., and in flower might be mistaken for that plant. Its fruits differ, however, in being unlobed, and thus serve to distinguish it. The plant of L. oxyphylius from which the material for our plate has been obtained was received at Kew from the Arnold Arboretum in 1895. It is perfectly hardy and thrives well in a loamy soil. Like its European ally it is a small tree, at present eight to ten feet in height, very graceful in habit and extremely DEcEMBER, 1915, attractive in September, when its branches are laden with brilliantly coloured fruits pendulous on long slender stalks. Each seed is completely enveloped in a fleshy scarlet imbricately five-lobed arillus. These seeds are produced in abundance and render its propagation easy. Description.—Shrub or small tree, in the wild state reaching 25 ft. in height with a trunk 1 ft. in diameter; winter-buds ovoid-fusiform, acute, about + in. long; branches spreading ; twigs of the previous season greenish- brown, polished ; of the present season herbaceous, green. Leaves assuming a distichous position from a twisting of the internodes, ovate-oblong, acuminate, subacute, rounded or almost truncate at the base, 13-3 in. long, 1-1} in. wide, thinly papery, dull, midrib slightly raised above, venation indistinct, paler beneath with nerves and venation very distinct ; petiole 1-1 in. long. Dichasia 2-3 times forked, arising in the axils of the lower leaves of the shoots of the previous year ; peduncle 13-2} in. long; pedicels 1-2 in. long. Flowers 5-merous, about 4 in. across.

The subject of our plate, Jris bracteata, has been in cultivation in the Iris Collection at Kew for a consider- able number of years, and the material for our figure has been obtained from one of the oldest plants therein. The species was discovered in 1884 by Mr. T. Howell, of Arthur, Oregon, in the Walds and Dear Greek Mountains of Josephine County close to the southern boundary of the state, where it flowers in the latter part of April and in May. Under the cultural treatment suitable for most species of /ris it thrives well in this country, flowering a fortnight later than it does in its native habitat. DecEMBER, 1915. According to Mr. S. Watson, the veining of the falls, so marked a feature in the plants grown in England, is not a constant character, while Mr. Dykes in his monograph of the genus /ris points out that under cultivation in this country, various colour varieties or hybrids have appeared in which the yellow of the flowers in the wild plant has been replaced by red, almost crimson ; in this case, however, the veining has persisted. Owing to the Jaxly branched rhizome J. bracteata is of somewhat scanty growth, the leaf-tufts and flowering stems coming up in a scattered fashion. The lowermost leaves just above the scales are reduced to the sheathing portion and only one, or occasionally perhaps two of the leaves belonging to a tuft are of the normal Jris type. Mr. 8S. Watson has pointed out that the stomata of the leaves are in this species confined to the pale side of the leaf. Derscription.—Herb, with a slender branching obliquely descending rootstock which is closely covered by the hardened remains of the firm bud-scales; leafy tufts clothed at the base by fresh firm brown imbricate scales. Leaves about four to each tuft, usually only one fully developed ; the two outermost very much reduced and sheathing almost throughout, the third about twice as long as the basal, sheathing for two-thirds of its length, the upper- most fully developed leaf sheathing at the base only and reaching 15-1} ft. in length ; all linear, acute, the larger about 4 in. wide, all green on one side, paler green or somewhat glaucous on the other, main-nerves about 8-10, slender but distinct. Stems with flowers 4-6 in. high to the bases of the spathes, clothed below with scales like those of the leafy tufts, the uppermost scales passing into leaves, usually 3 in number, which are — reduced to sheaths 13-3 in. long. Spathes lanceolate, acuminate, 2-21 in, long, green, with thin membranous margins, slightly keeled along the centre behind. Flowers 2; pedicels 13—-2in. long. Perianth with a funnel-shaped tube 2-21 in, long; outer segments with an oblong- ovate, spreading limb about 13} in. long and 3 in. wide gradually narrowed to a wide claw about 2 in. long, yellow with 4 brownish-purple, longitudinal veins of which the outer pair give off numerous lateral branches of the same colour that pass obliquely outwards to near the margin; inner segments erect, limb oblong, obtuse, contracted to a narrow claw, uniformly yellow. Anthers yellow, over } in. long; filaments short, slightly hairy. Ovary oblong, 4-3 in. long; style-arms broad, linear, with a distinct subquadrate crest and crenulate lobes ; stigma wide-triangular. Capsule oblong, terete. Seeds somewhat cubical, cuneate.

Prunus Maximowiczii belongs to the Mahaleb section of the cherries, but is distinguished from the other cultivated species of that group by the conspicuous foliaceous bracts on theinflorescence. Jt is closely allied to P. szechuanieca, Batalin, a species probably not in cultivation, which differs by its subumbellate inflorescence, its much shorter peduncle but longer pedicels and by its conspicuously glandular bracts very villous beneath. Originally discovered in Eastern Manchuria and described by Ruprecht in 1857, P. Mazximowiczu has since been found in Japan, Sachalin and Corea. It did not reach this country until 1895 when it was sent to Kew by Prof. Sargent from the Arnold Arboretum, to which establish- December, 1915. ment he had introduced it from Japan three years previously. It has succeeded very well and proved to be quite hardy, forming a small tree of neat shape. The material used in the preparation of our plate was kindly supplied by Mr. T. Smith from his well known nursery at Newry, where the tree apparently bears fruit more freely than it does at Kew. There is some varia- tion in the degree of pubescence on the leaves. On Mr. Smith’s plant it is almost confined to the midrib and veins beneath, but on one grown in the Kew collection the leaves are softly villous beneath. The glands on the teeth of the bracts and calyx-lobes also vary in their frequency and size. The foliage of this cherry turns a fine red colour before falling in both Japan and North America, but, owing probably to our duller skies, has not shown this quality with us. Description.—7ree, 20-30 ft. high, of spreading habit, young shoots clothed with pale hairs the first season, glabrescent and greyish-brown the second. Leaves ovate, oval, or obovate, cuneate to rounded at the base, shortly acuminate, irregularly and doubly — serrate; 13-4 in. long, 2-13 in. wide; dull green, glabrous or slightly pubescent above, pubescent beneath especially on the midrib and veins; petiole villous, eglandular, 4-% in. long; stipules linear, serrate, }—1 in. long, pubescent. tacemes corymbose, 1-2 in. wide, usually 5-8-flowered, produced on short leafy shoots.
