H. Wilson informs us, it occurs scattered throughout woods without being anywhere common. It was first collected by Professor A. Henry, in 1885, near Ichang, and was met with again by him in subsequent years. Wilson obtained it in 1901 near Fang. In its native habitat this is the : last of the Rhododendrons to come into flower and, as it maintains this characteristic in cultivation, this fact imparts to #. auriculatum its most important feature from the garden point of view. At Kew, where the species 1s represented by examples acquired from Messrs. J. Veitch and Sons in 1908, it does not commence to JanuaRy—Marcg, 1919. a. grow until the latter part of July, and it flowers at the same time. It may therefore be possible to found on it a race of hardy hybrids later in flowering than any now in existence, though it is difficult to find other Rhododen- drons flowering in July with which it can be crossed. At Kew it has been fertilised with pollen from a belated f. ponticum, Linn. ; it has also been crossed with the late- flowering form of R. decorum, Franch. In the wild state the flowers of /?. auriculatum vary, so Wilson states, from white to rosy red. They are pleasantly fragrant, their odour recalling that of a freshly cut dessert apple. In foliage it is perhaps the finest of all Rhododendrons hardy in aclimate like that of the Thames valley, though in milder districts larger leaves are borne by Himalayan species like . Falconeri, Hook. f., and £&. grande, Wight. The largest leaves of 2. auriculatum measured have been thirteen inches long by five inches across. Though quite hardy at Kew, its greater luxuriance in Cornish gardens indicates that it prefers rather milder conditions. It should be grown in thin woodland or in some other position where it is protected from the midday sun. Description.—Shrub or, according to Henry, at times a tree 30 ft. high; shoots stout, in the first season densely hirsute with very long glandular hairs, in the following year pustulate with the remains of the hairs, when older, brown and glabrous. Leaves oblong or elliptic-oblong, rounded or orbicular, about 13 in. long. Stamens 14, shortly exserted; filaments nearly equal in length, glabrous; anthers brownish-yellow, 2 in. long. Ovary 7-8- celled, densely beset with glandular hairs; style exserted, glandular towards the base, tipped by the in. long, over } in. wide, glandular-hairy.

The remarkable Brazilian Orchid which forms the subject of our plate was described and figured by Mr. Barbosa Rodriguez in 1877 from specimens growing on trees at Caldas, in the province of Minas Geraes. It had, however, been previously met with by Dr. G. Gardner, for there is a specimen of the same plant in the Lindley Herbarium which Gardner has noted as being a species of Mazillaria, collected by him in March, 1837, on the. stems of trees in the Organ Mountains. To this speci- -men Dr. Lindley added the note, ‘‘ genus uncertain, the only flower was broken and injured by insects.” Rodriguez when he described the plant, which he dedicated to H.I.H. Donna Isabel, Comtessa d’Eu, remarked that it is a very bizarre Orchid with almost the habit of a Mazillaria, but with a pollinary structure JaNuaRY-Makrcg, 1919, ae so different from that of Mavillaria that he placed his genus /sabelia, with good reason, in the tribe Epidendreae, between Lindley’s two genera Leptotes and Sophronitis. In the figure of J. virginalis supplied by Rodriguez, which serves as the frontispiece to his volume, the remarkable fibrous sheaths which clothe the pseudobulbs are shown as being more developed than they are in the cultivated plant here depicted. For the introduc- tion of this plant to cultivation, orchid-growers are indebted to Mr. K. Grossman, who sent living plants to the Botanic Garden at Berlin in 1904. The example now figured was received at Kew from the Director of the Berlin Botanic Garden in 1908, and has thriven well in an intermediate temperature attached to a block of tree-fern stem. © Under cultivation it flowers very Sparingly, the last occasion being December, 1917, when our drawing was prepared. It is by no means con- spicuous, even when in flower, for the solitary individual blossoms are small, and are borne on extremely short peduncles ; they are whitish with a light flush of rose or pale purple in the sepals. The flowers are, however, extremely interesting on account of their remarkable structure. Description.—Herb, epiphytic, small, with a creeping cylindric rootstock. Pseudobulbs 1-foliate, close-set, ovoid-globose, 3-3 in. long, clothed with Scarious sheaths which at length become fibrous-laciniate. Leaves nearly cylindric, rather blunt, curved or flexuous, 13-6 in. long, very narrow. Scapes short, slender, 1-1 in. long, 1-flowered ; bracts spathaceous, blunt, very short; . pedicels short. Flowers small, spreading, flushed with rose or pale purple. Sepals : posterior suberect, ovate-oblong, blunt, somewhat concave, 1-1 in, long ; lateral somewhat spreading, ovate-oblong, blunt, } in. long, shortly connate at the base and produced into a short mentum. Petals somewhat spreading, narrow- oblong, blunt, 3-1 in. long, somewhat narrowed at the base.

This Jpomoea, attractive both in foliage and in flowers, the latter being of a colour very unusual in the genus, has long been known in gardens. Its first recorded | appearance was in the Calcutta Botanic Garden in 1812, where, according to Roxburgh, it sprang up accidentally amongst plants received from friends in the vicinity of Calcutta ; of its native place he was uncertain. Under the name of J. tuberculata it was figured and described in the Botanical Register in 1816, and it is there stated that the plant was raised from seeds collected in the Calcutta Botanic Garden, and sent by Sir Evan Nepean, it would appear early in 1815, to Messrs. Whitley, Milne and Brame, Nurserymen of King’s Road, Chelsea. Jacquin first met with it in the Vienna University Botanic Garden, where, he informs us, it was obtained amongst several unnamed Chinese seeds received from England in 1814. The species appears to have a wide distribution, but very probably it is not a native in some of the localities from which it is recorded. In India it is known from Simla, Rohilcund and the Deccan Peninsula. It is also known from Ceylon “in dry country, very rare,” and from Java. There is no satisfactory evidence that it is native in China and Australia, though these countries are included in its range by various authorities. In Tropical Africa it ranges from Nubia, Abyssinia, the Egyptian Sudan, German East Africa to the Kwebe Hills in Ngamiland, and Upingtonia in South-West Tropical Africa. There is a very small-flowered speci- men in the Kew Herbarium labelled, possibly incorrectly, “C.B.S. Villette.” The material for the accompanying figure was obtained from a plant raised from seeds received in 1917 from Major Howard of Richmond, and collected by him at Kilimatinde in German East Africa. The flowers vary considerably in size as shown by the plant cultivated at Kew, as well as by the dried speci- mens, and forms with unusually large flowers have been supposed to represent distinct species and have been described as such. It is possible also that the colour varies, for in one instance the flowers are said to be white. The curious little pouches, sometimes very conspicuous at the base of the outer sepals, appear to differ in size and in some of the dried specimens are scarcely noticeable. It is almost certain that J. saccata, - Hallier f. (in Engl. Jahrb. vol. xxviii. p. 48), from German East Africa, of which there is no specimen at Kew, should also be referred to 7. dasysperma. At Kew the species has been raised and flowered in a tropical house. Description.—Herb, apparently annual, everywhere quite glabrous. Stems twining, 6-8 ft. high or more, very slender, simple or sparingly branched, at times tuberculate. Leaves petioled, wide cordate-ovate,.13-4 in. long and broad, 3-sect with the main lobes more or less narrowed at the base, and the central lobe 8-partite while the lateral are 2-3-partite, or at times pedate ; lobes lanceolate, acute or acuminate, quite éntire, 2-8 in. long, }—3 in. wide; petioles {2 in. long, occasionally with rudimentary leaves resembling stipules in their axils. Peduncles axillary, 14-1} in. long, 1-3 (rarely 4)-flowered, with a few minute bracts. Sepals 5, elliptic with rounded tips, 1-2 in. long, 3-1 in. wide, their margins membranous, their bases outside with 1 or 2 small pouches or spurs. Corolla salver-shaped, glabrous; tube 1-1} in. long, 1-2 in. wide about the middle, narrowed at the base, pale purple throughout and deep purple at the throat; limb flattened, somewhat 5-angled, 23-4 in. across, from straw- colour to sulphur-yellow, with 5 narrow greenish bands. Stamens 5; filaments pilose at the base; anthers oblong. Ovary nearly globose, glabrous, encircled at the base by a narrow but stoutish disk; style filiform, included, longer than the stamens; stigma 2-lobed.

Fructus haud visus.—J. HurcHinson. The charming Rhododendron here figured was first met with by Mr. G. Forrest on the western flank of the Shweli- Salwin divide in south-western Yunnan in August, 1912, at elevations of about 10,000 feet and was found again by the same collector at similar elevations on open rocky slopes in the following June. Described at Edinburgh from specimens of the second gathering, R. callimorphum is now in cultivation in various collec- tions in this country and appears to be fairly hardy at Caerhays Castle in Cornwall, whence Mr. J. C. Williams, with whom alone it has yet flowered, supplied the material for our plate ; also at the Sunningdale Nurseries JanuaRy-Marcg, 1919, where, as Mr. H. White informs us, it has more than once experienced very severe frost, but has escaped with only slight injury; and at Kew where an example which has lived out of doors for five years is quite healthy. _In cultivation it has so far grown into a compact shrub about three feet high, bearing some outward resemblance to R. campylocarpum, Hook. f., figured at t. 4968 of this work; its nearest ally, however, is R. Souliei, Franch., described at t. 8622. Marked features of R. callimorphum are its long petioles covered with red or blackish stalked glands, and its nearly cordate ovate-orbicular leaves with a distinct bloom on the underside. Occasionally one of the uppermost leaves is considerably reduced in size and spathulate in shape, while the petiole is widened and winged. It is not clear that this is a frequent feature in f. callimorphum; it arrests attention owing to its rarity in species of Rhododendron proper, though it is of common occurrence in the Azalea section of the genus. It is perhaps too soon to predict the situation that will best suit 4. callimorphum and lead to its attaining the dimensions of wild specimens. Those in shady positions are, however, at present growing more freely than those in fairly open spots. _ Descriprion.— Shrub, in nature reaching 10 ft. in height, laxly leafy ; twigs rather straight, cylindric, becoming brown towards the base and nearly. glabrous when a year old, pale green upwards, beset with a few brown short- stalked glands, when older smooth, faintly punctate, about } in. thick.

It has grown satisfactorily in a sunny tropical house where it flowers in the autumn and suckers rather freely. The original plant flowered at Kew for the first time not in autumn but in April, 1895, and when it was then described by Mr. Baker it still had “laxly rosulate ” leaves, but by 1901 it had developed a stem thirteen inches high with scattered foliage. From the suckers several independent plants have been raised and one of these, which forms the subject of our plate, flowered at Kew in October, 1916. One of the plants had by October, 1918, developed two stems, eleven and thirteen inches high respectively, with five basal offsets from one to two inches in height. The stem is relatively slender, and the naked portion is conspicuous on account of the JanvaRy-Maxca, 1919, | ries | gradual increase in thickness from the base upwards. Though erect or at least ascending in these cultivated plants, the appearance of the stem suggests that in wild ones it may be more or less prostrate, a suggestion strengthened by the inclined position assumed by the inflorescence. The leaves, which are remarkable for their closely set silvery white spots, are relatively small for the genus; their sheaths are rather long and com- pletely encircle the stem. It is singular that since its original discovery this species has not again been met with in a wild state. In the division of the section to which A. concinna belongs are included two other Aloes, both nearly related to our plant, yet both readily dis- tinguished from it by their flowers, for one of them, A. squarresa, Baker, a Socotran Species, has a shorter perianth, while the other, A. Dorotheae, Berger, a species of German East Africa, has a longer perianth than A. concinna. : Dzscription.—Undershrub with a distinct stem, 8-13 in. high, and succulent leaves.

The material on which our figure of the pleasing Primula now described has been based was received from Sir F. W. Moore, by whom it had been grown at the Royal Botanic Garden, Glasnevin, under the name P. chasmophila, Balf. f., in April, 1918. It is a native of Bhutan, where it was obtained by Mr. Cooper when collecting on behalf of Mr. A. K. Bulley, Neston, Cheshire, through whom the plant figured had reached Glasnevin. Professor Balfour, to whom the plant owes its name, has kindly informed us that Mr. Cooper’s original material was all in fruit, and that although the plant flowered in the Royal Botanic Garden, Edinburgh, in 1917 the blossoms were mostly so imperfect as to render it desirable to defer the preparation of a full JaNuARY-Manrcu, 1919, description. In Bhutan the species is met with in dry sunny positions in rocky soil at about 16,000 feet above sea-level. P. chasmophilais a member of the Soldanelloides section of the genus, whereof there are several species in the eastern Himalaya and Western China, most of them characterised by their diminutive size and relatively small leaves associated with large and conspicuous flowers, though usually they enlarge considerably after flowering. Perhaps the extreme of this condition is met with in P. uniflora, Klatt, a Sikkim species in which the leaves are remarkably small while there is but a single large flower. The nearest allies of P. chasmophila are the Chinese P. spicata, Franch., and the Himalayan P. Wattii, King. Description.—Herb, about 8 in. high.

Baron in the Central District of Madagascar. In 1914, a living plant of a Madagascar Bulbophyllum was presented to Kew by Sir F. W. Moore, Royal Botanic Garden, Glasnevin, and on flowering proved to be identical with the species discovered by Mr. Baron more than twenty years earlier. The species belongs to a somewhat small group of Bulbophylla in which the rachis of the inflorescence is clavately thickened. The shortly pedicelled individual flowers are tightly adpressed to the rachis, and are considerably dilated laterally, while the fleshy lip is immersed in a cavity formed by the united lateral sepals, the margins of these being denticulate. The nearest ally of B. robustum is B. crenulatum, Rolfe, — another Madagascar species, figured at t. 8000 of this — Janvary-Marcg, 1919. : : work. Our plant differs from 2. crenulatum in its stouter habit, its larger flowers and in the entire in place of denticulate angles of the ovary. The plant is grown in a basket suspended from the roof of a tropical house at Kew, and thrives well under the treatment suitable for other tropical species of the genus. It flowered at Kew in May, 1917, when the figure now published was pre- pared. Description.—Herb, epiphytic; rhizome creeping, stout, tightly clothed with ovate acute imbricate sheaths.

Srapr, Protea longifolia, the subject of our plate, has had Holland, on the boundary of the ‘Stellenbosch and Caledon divisions of Cape Colony. The field-notes at his disposal enabled him to state that there it is rare, grows on mountain-slopes, has wide-spreading roots, a trunk about as thick as one’s arm, which branches about JanuaRy-Marcg, 1919, eighteen inches above the soil-level and attains a height, with the branches, of some three feet. Burchell, who collected it nearly a century later in the Donderhoek Mountains near Villersdorp in northern Caledon, found it to be there very common, reaching a height of five to seven feet and resembling closely P. mellifera, Thunb., a native of the Coast Region of South Africa. The area occupied by P. longifolia covers practically the whole of the Caledon division and, if we include the form with smaller leaves and heads, which Mr. Phillips separates as var. minor, the species extends into the adjoining portion of the Bredasdorp division. Whether it were introduced in the time of Boerhaave or not, we know that towards the close of the XVIII. Century it was raised at Schén- brunn, from seeds sent or brought there probably by the Austrian collector Scholl. Messrs. Lee and Kennedy, of Hammersmith, received from Schénbrunn a plant or plants which flowered in their nursery early in 1801, and were figured by Andrews as P. longifolia nigra in the “Repository.” But the same firm seem to have obtained, also from Schénbrunn, other specimens which likewise flowered in 1801 and were figured by Andrews as P. longifolia ferruginoso-purpurea. About the same time Hibbert had yet another specimen, likewise sent from Schénbrunn, which Andrews described and figured as P. longifolia, var. cono turbinato. But while Andrews was satisfied that all three were forms or varieties of P. longifolia, Sweet regarded them as distinct species which he named P. longifolia, P. ligulaefolia and P, um- bonalis respectively. A fourth figure purporting to represent P. longifolia was published in the ‘* Botanical Register” in 1815. The plant in this case was again one belonging to Messrs. Lee and Kennedy ; this time, however, it was one introduced by Masson in 1790. Sweet accepted Masson’s plant as true P. longifolia, but Phillips, relying on certain differences exhibited in t. 47 of the “ Register,” has treated it as the basis cf a dis- tinct species, P. ignota. In the ‘Flora Capensis”’ P. ligulaefolia and P. umbonalis are similarly recognised. As no specimens of P. ignota, ligulaefolia or umbonalis appear to have been preserved when their respective plates were published, this course is possibly safer than the alternative one of including all three under P. lonyi- folia. But while there is no conclusive evidence to justify the reduction of the three species proposed or accepted by Sweet and Phillips, it has to be remarked that the appearance of the flower-heads in the plant now figured suggests that these heads do not develop per- fectly and normally in our relatively sunless climate. This in turn raises the question whether those differences in the shape of the centre of the head, the length of the _ perianth-arms, and the colouring of the involucral bracts on which the separation of P. ignota, P. ligulaefolia and P. umbonalis from P. longifolia depends, may not be fully explained by the adverse conditions with which any Protea has to contend when grown in this country. The plant now figured was raised at Kew from seed collected in the Caledon division by Miss M. Mason, to whom the establishment is indebted for many interesting South African plants. The seed was despatched from the Cape in March, 1911; the plant depicted was cultivated in a pot in a greenhouse where it has thriven well, and where it flowered for the first time, at an unexpectedly early age, in October, 1916. Description.—Skrub, 8-7 ft. high, with finely tomentellous or almost glabrous branches.

It is now nearly eighty years since the Mexican Orchid here figured was first described by Professor Lindley. The original plant flowered in the collection of Mr. John Rogers, junior, Vine Lodge, Sevenoaks, who had imported the bulb. Mr. Rogers, who called Professor Lindley’s attention to the character of the leaf-sheaths, remarked that the innermost one, which surmounts the bulb, is about eight inches high, and two to three inches in diameter at the base, but only three-quarters of an inch wide at the throat, translucent or semi-transparent and containing about a third of a pint of water. The pitcher is generally full, all the rain and dew on the leaves being January-Marcy, 1919. “ entire, and resembles a Florence flask in shape, being conducted into it; this water appears to be absorbed by © the plant because if not replenished it disappears more rapidly than evaporation would account for. Lindley at a later date reduced his Govenia lagenophora to his G, utriculata, a West Indian species, first described by Swartz as Cymbidium utriculatum, but it is now known that the Mexican and the West Indian plants are very distinct and easily discriminated by the features men- tioned by Mr. Rolfe. The original specimen of G. layeno- phora does not seem to have been preserved, but the letter from Mr. Rogers, accompanied by a sketch, is in the Lindley herbarium, and at a still later date Professor Lindley identified dried specimens collected by Hartweg on the Monte de la Virgin as being identical with Mr. Rogers’ plant. Since then the species seems to have remained unknown until, in September. 1907, Mr. Juan Balme, of Hijo, Mexico, sent a sketch of an orchid, collected in the State of Vera Cruz, along with a living bulb. The latter produced flowers in the Kew collection in 1908, and at last enabled the confusion between G. lagenophora and G. utriculata to be settled. Mr. Balme’s plant has been grown in a warm house, and is given an abundant supply of water except when the leaves die down. Under this treatment it has flowered on several occasions since 1908; our drawing was pre- pared when it did so ce ie gore 1916. At the time of flowering the characteristic utricle does not appear to be fully developed. Desoription.—Herb, terrestrial. Pseudobulbs ovoid, 2-2} in. long, clothed with membranous sheaths.

It flowered at Kew in July, 1913, when the accompanying figure was pre- ed. At the same time flowering specimens were received from Glasnevin, gathered from a plant which had been presented to that establishment by Mr. de Vilmorin also. The Kew plant is now about 4 ft. high, bushy, and evidently very hardy. It is about the latest of the Deutzias to open its flowers, and this not only adds to its value as blossoming at a season when shrubs in flower January—Marcg, 1919, : are becoming scarce, but also enables it to escape the late frosts which, at Kew at any rate, almost every year ruin the display of most of the species. Its flowers are pretty and distinct in their compact arrangement, their smali size and large numbers, characters which dis- tinguish it from D. rubens, Rehder. The Deutzias enjoy a good loamy soil and abundant sunshine, and are easily increased by means of cuttings put in in July. DistriputTion.—Shrub, probably 5-6 feet high, of bushy habit; young shoots terete, furnished densely with stellate pubescence; bark becoming dark brown and peeling the second season. Leaves oblong-lanceolate, acuminate, rounded at the base, finely serrate, those of the barren shoots 8 in. long, 1} in. wide, those of the flowering twigs j-1} in. long; conspicuously nerved, the chief lateral nerves 5-9 along each side the midrib, impressed above, prominently raised beneath; dull dark green above with scattered stellate hairs, paler beneath and almost covered with minute, 5-8-rayed stellate hairs ; petiole 3-1 in. long, grooved on the upper side. Corymbs terminal on short leafy twigs, rounded, compact, many-flowered, about 2 in. across. Flowers 3-8 in. wide ; peduncle and pedicels scurfy. Receptacle campanulate, qs in. long. Sepals zz in. long, ciliolate, acute, clothed like the receptacle with minute adpressed stellate scales. Petals imbricate, orbicular, % in, in diameter, white tinged with pink when young. Stamens 10, 2-seriate, shorter than the petals; the filaments white, those of the outer row diverging at the top into a pointed wing at each side of the anthers, those of the inner row shorter; anthers at first red, then brown.

The charming little Primula here figured was raised at Kew from seeds collected by Mr. R. E. Cooper in Bhutan in the Eastern Himalaya for Messrs. Bees, Limited, by whom their supply was shared with this establishment in 1915. The species, which was for the first time described as P. tibetica by Sir George Watt in 1882, is a native of alpine Sikkim and Bhutan at elevations of 16-17,000 feet above sea-level, and of the adjacent provinces of south-eastern Tibet. It was originally discovered by Sir J. D. Hooker, now seventy years ago, on the Sikkim frontier of Tibet. It bears a rather close resemblance to the more northern P. sibirica, Jacq., in which species, however, the scape is usually much longer and stouter, while the pedicels are shorter and the. January--Marcu, 1919. calyx-lobes have a fringe of minute glandular hairs that is absent from P. tibetica, Distinctive features of this Himalayan species are the pronounced yellow “ eye’? and the gibbous bracts. At Kew P. tibetica has proved hardy and has thriven well in the Rock-garden, but like so many other members of the genus it proves in culti- vation to be monocarpic and dies after flowering and ripening its seeds.

It is a native of the island of Formosa where it was first discovered, over twenty years ago, on Liko Hill, near Tamsui, by Mr. H. B. Morse, of the Chinese Consular Service. The upper portion of the raceme of Mr. Morse’s original specimen, which was communicated to Kew by Professor A. Henry, had been lost; a single flower, however, remained attached to the base of the inflorescence, and thus admitted of the preparation of a description of the species, as L. macrantha. The plant was met with again by Mr. H. J. Elwes in the low country near Taikow in Formosa, and a living specimen brought by him to England flowered for the first time in his collection at Colesborne, Cheltenham, in February, 1916. From this plant, which was then presented to Kew by Mr. Elwes, Aprit-JuNE, 1919, the plate now given has been prepared. The species belongs to the section Molliaefoliae, and is a striking plant on account of its large undulate leaves, its long raceme of vinous-purple flowers, and its large lip which is strongly toothed on the margin. At Kew L. macrantha has thriven well in a tropical Orchid House under the conditions and treatment suitable for Indian species of Calanthe. Descriprion.—Herb, terrestrial. Stem erect, rather stout, 4-6 in. high. Leaves petioled, spreading or recurved, ovate-elliptic or broadly elliptic, subacute or shortly acuminate, undulate, plicate, membranous, 4-6} in. long, 2-3 in. wide ; petiole 1}-1} in. long, dilated and sheathing at the base.

Of the genus Pyrus as conceived by Linnaeus and adopted by Bentham and Hooker, the section Malus, or the crabs, is poorly represented on the continent of North America, some four or five species only being found there ; the pears (Pyrophorum) are not represented at all. Malus rivularis is the only crab found west of Aprit—J tye, 1919, oe the Rocky Mountains where, however, it extends over many degrees of latitude, reaching from Alaska through British Columbia, Oregon and Washington to California. It belongs to the same group of crabs as M. Toringo, Sieb. and M. Sargentii, Rehd., figured at t. 8757 of this work, all characterised by the calyx falling away from the apex of the fruit. From both the other species M. rivularis is well distinguished by its ellipsoid fruits and by the shorter lobes of the calyx as compared with the calyx-tube. The fruit has a rather pleasant acid flavour and is variable in size and colour. On our plant, which was obtained for Kew from a continental nursery in 1905, they appear to be larger and more cylindrical than is usual. According to Sargent this crab in a wild state affects moist situations where the soil is deep and rich, often forming in such places large impenetrable thickets. Archibald Menzies, the surgeon and botanist attached to Vancouver’s expedition of "survey, appears to have been the first European scientific observer to find it, which he did about 1793. David Douglas collected it some thirty years later, and it is said by Loudon to have been introduced in 1836. It has never been much cultivated in English gardens, although it is very hardy and grows vigorously, and is quite attractive when laden with its distinct and hand- some fruits. Description.—Tree, 15-30, sometimes 40 ft. high, the trunk 1-13 ft. in diameter; young shoots clothed with grey hairs at first, becoming glabrous; purplish-brown the second season. Leaves deciduous, ovate to ovate-lanceolate, acute or acuminate, usually rounded or occasionally cuneate at the base, sometimes obscurely lobed above the middle, finely and sharply serrate ; 13-33 in. long, 3-13 in. wide; dark dull green, and at first puberulous above, finally glabrous ; paler and pubescent beneath ; petiole }-14 in. long, pubescent. Flowers 3-1 in. wide, terminal or produced in the axils of the terminal leaves, 8-12 forming a corymb 2-3 in. wide, expanding in May. Calyx-tube obconic, pubescent; lobes 5, lanceolate, ;3: in. long, slightly pubescent or glabrous outside, thickly covered with pale grey wool within. Petals 5, orbicular with a short claw and a few jagged teeth near the base, % in. long, creamy white. Stamens 16-20; filaments glabrous, flattened.

The genus Wittia is singular among the Cactaceae in combining with the habit of Phyllocactus and Epiphyllum the character of possessing very small flowers. It was originally described by Dr. K. Schumann in 1911, and was based on a Peruvian species which he named W. amazonica; the plant in question was collected by Mr. Ule near Lacaitia and also near Tarapoto. The description of W. amazonica had just appeared when in October, 1911, a second species was met with by Mr. H. Pittier on the mountains above Chapo in Panama. This plant flowered at Washington some months after- wards and in due course was described and figured by Messrs. Britton and Rose as Ji’. panamensis. In 1914 | a plant of W. panamensis was presented to the Kew collection by Mr. D. Fairchild, Department of Agriculture, Washington. This plant, which has thriven well in the Succulent House at Kew, flowered there in May, 1917, Aprit-JuNE, 1919, : . ~ . when our figure was prepared. Since then Britton and Rose have been able to describe, as JW. costaricensis, yet another species, also collected by Pittier, but on this occasion on the west coast of Costa Rica. Britton and Rose also remark that Wéittia is a strange genus, having stems resembling those of Epiphyllum and Rhipsalis, with flowers very different from those of either of these genera. Description.—Herb, with succulent, sparingly branched, elongated, flattened stems, which are leafy in appearance, are distantly crenate along the margin, exhibit a stout median rib, and attain a width of 13-13in. Flowers axillary, borne at the bases of the crenations, 1-1} in. long, deep purple. Calyx with a rather slender tube about 2 in. long, which is produced well beyond the ovary, and clothed at the base with a few minute scarious scales; lobes 10, 2-seriate, erect, petaloid, oblong and blunt at the tip, those of the outer series faintly keeled, of the inner series rather longer and of thinner consistence. Petals 10, erect, oblong, apiculate, white, rather shorter than the sepals. Stamens many, included, 13-14 in. long; filaments slender; anthers oblong.

The Honeysuckle here figured was originally discovered by the late Abbé Delavay in South-Western China, and was at first regarded by the late Mr. Franchet as a distinct species which he named in compliment to its distinguished collector. The more ample material now available has, however, led Mr. Rehder to think that it is only a glabrescent variety of Lonicera similis, Hemsl. The plant from which our figure has been prepared was presented to Kew in 1910 by the late Mr. M. L. de Vilmorin, who had raised plants at Les Barres from seeds received from South-Western China in 1901, some of which flowered for the first time in 1904. Among the nearer allies of L. similis, var. Delavayi, are L. macrantha, Wall., from which it differs in having a longer, glabrous corolla-tube, and L. longijlora, DC., from which it is Aprit—JuNE, 1919, easily distinguished by the leaves being grey-tomentellous beneath and cordate at the base. All three belong to the group Longiflorae of the section defined as Nintooa by DeCandolle, within the subgenus Chamaecerasus. A climber of vigorous growth, L. similis, var. Delavayi, is very hardy and, being evergreen, promises to be a useful addition to a group of shrubs rather scanty in outdoor collections—the hardy evergreen climbers. Another useful quality of our plant is the circumstance that it flowers as late as August. It thrives very well in a loamy soil and can be increased by late summer cuttings. Description.—Shrub, climbing, evergreen; branches terete, glabrous.

The pleasing Primula here figured is a native of the Eastern Himalaya, belonging to the Capitatae section of the genus, from all other members of which it is dis- tinguished by its doubly and rather coarsely toothed membranous leaves which are adpressed _ strigose- pubescent on both surfaces. It has been regarded by Sir George Watt as the East Himalayan representative of the well-known P. farinosa, Linn., which extends from North America through Europe to Western Tibet. Our species was first discovered on Alpine slopes in Sikkim, at elevations of 13,000 feet, by one of the native collectors employed by Sir George King, who, recognising it as distinct, gave it the name P. bellidifolia, The plant Aprit-JunE, 1919, ; from which our figure has been prepared was one of a number raised from seed presented to Kew in 1915 by Messrs. Bees, Limited, for whom it had been collected in Alpine Bhutan in 1914 by Mr. R. E. Cooper. The species has thriven well at Kew, and plants put out of doors in the Rock Garden flowered freely in May. Other plants grown in pots in a cool frame flowered equally freely and were exhibited in the Alpine House. Like its allies P. farinosa, Linn., and P. denticulata, Sm., between which it is in general features intermediate, P. bellidifolia has proved monocarpic. The plants in this instance, how- ever, though behaving as if quite hardy, unfortunately died after flowering without ripening their seed. Drscription.—Herb, up to 10 in. high.

The Ahododendron now figured was first met with by the Abbé Delavay, between 1883 and 1885, on the mountain Tsang-chan, overlooking Tali in Yunnan, at about 6,700 feet above sea-level, and was described by Mr. Franchet in 1886 as 2. oleifolium. It was met with again in 1906 by Mr. George Forrest, on the eastern flank of the Tali range, Lat. 25° 40’ N., in open alpine pastures at altitudes of 8—10,000 feet, as a dwarf shrublet a foot. to two and a half feet high, with blossoms varying in colour from white to pale rose. The plant from which our illustration was made was raised at Kew under glass, from seed obtained from Messrs. Bees, Limited, early in 1915. It flowered in May, 1917, when only two years old, Aprit-June, 1919, . thus sharing with /2. racemosum, Franch., another Yunnan species already familiar owing to its suitability for culti- vation in masses in flower-beds, and already figured at t. 7301 of this work, the characteristic of producing its blossoms at a very early stage of its career. Another feature which £. oleifolium shares with its near ally ft. racemosum is that rare character in Rhododendrons, the production of solitary axillary flowers. To this peculiarity is due the distinctive habit of these two species; their leaf-bearing buds as a consequence are always terminal, and a primary shoot, having once flowered, never branches again save when it has been injured. Although the particular plant of R. oleifolium now depicted was raised under the protection of a cold frame we believe the species may prove hardy, for other plants, grown out of doors, have shown no signs of tenderness as yet, though the species has not been sufficiently long in cultivation to admit of our judging how resistant to English weather conditions it may be as compared with its better known ally, 2. racemosum. From that species R. oleifolium is readily distinguished by the longer and narrower leaves, and especially by the presence of a soft hairy indumentum on the outside of the corolla-tube as well as by the lepidote style. Descripti0n.— Shrub of small size, reaching a height of 23 ft., laxly branched upwards; stem yellowish-grey, glabrous; shoots of the second season rusty, finely lepidote; new shoots densely lepidote. Leaves lax, lanceolate or oblong- lanceolate, acute, narrowed or somewhat rounded at the base, 1-2} in. long, 378 in. wide, papery, at first lepidote, but soon glabrous and dull green above, somewhat glaucous and lepidote beneath, the scales small and fleshy and rather further than their own breadth apart; midrib sunk above, raised beneath ; lateral nerves 8-10 along each side, raised beneath ; petiole 4-1 in. long, without scales. Flowers solitary or in pairs, axillary; flower-buds narrow ellipsoid, about 2 in. long before the flowers open, their scales brown, without scales outside, the uppermost finely ciliolate, pedicels very short and hardly exserted from the scales, densely lepidote.

Calanthe tricarinata is an old and well-known Orchid, which was first discovered by Wallich in Nepal in 1819. Since then it has been met with by various collectors in many other localities in the north-west Himalaya. In the “‘ Flora of British India” its habitat is given as the temperate Himalaya, at elevations of 5000-9000 feet, from Kashmir to Nepal. Soon after this announcement, which was made in 1890, the species was found in Sikkim, by Pantling, at an elevation of 6000 feet, in the Lachen valley. But it had already been reported by es Maximowicz to occur in grassy woods near Lake Conoma, =o in Japan, and it was from Japan that the species was : first introduced to cultivation in this country. This introduction was in a sense accidental; the species was found among some plants of C. Textorii, Miq., imported AprRIL~J UNE, 1919. by Messrs. J. Veitch and Sons in 1879. Between the time of its discovery in Japan and of its being met with in Sikkim, Mr. A. Henry had collected C. ¢tricarinata in the northern mountain forests of Yunnan at an elevation of 7000 feet. In cultivation C. tricarinata thrives well under the conditions suitable for other species of the genus, such as C. Masuca, Lindl., figured at t. 4541 of this work. The plant now figured flowered in April, 1916, in the collection of Mr. H. J. Elwes, at Colesborne Park, Gloucestershire, and was afterwards presented by Mr. Elwes to Kew. It is understood that this particular plant was obtained by Mr. Elwes from Sikkim. In spite of its wide distribution and of its introduction forty years ago, C. ¢tricarinata has always been a rare plant in cultivation. It has, however, been used as one of the parents of a garden hybrid, C. //arryana, raised by Messrs. Veitch, the other parent in this case being C. Masuca.

The plant here figured was originally described as a variety of Lonicera hispida, Pall., but the characters given above seem to be sufficiently definite and constant to separate it from that very variable species. Following the classification of Rehder, this species, which he terms L. chaetocarpa, is to be included in the Bracteatae group recognised by Hooker and T. Thomson within the section defined as Jsika by DeCandolle, and thus falls within the subgenus which Linnaeus termed Chamae- cerasus. The original specimens of L. chaetocarpa were collected in Kansu, but the plant has since been met with both in Szechuan and in Eastern Tibet. It was introduced to cultivation by Mr. E. H. Wilson in 1904 when collecting in Western China for Messrs. Veitch, and Aprit-J UNE, 1919. the material from which our figure has been prepared was taken from a plant purchased from that firm in 1913. The Kew example is now a shrub about five feet high, of neat, rounded habit, and is evidently perfectly hardy. At Kew it is, indeed, regarded as one of the best and most satisfactory of the newer shrubby honey- suckles. It likes a good loamy soil and is easily increased by means of cuttings put in sandy soil in gentle heat during July and August. Its flowers open in early June and are of a pleasing primrose yellow.

The Desmodium now figured is a native of South- western China first gathered over thirty years ago by the Abbé Delavay, by whom it is reported to occur on chalky hills near Lankong in Yunnan. It was first described from material sent by Delavay to Paris. Later it was met with by Mr. A. E. Pratt near Ta-chienlu in Szechuan, and a few years ago it was found again by Mr. G. Forrest on the eastern flanks of the Li-Kiang Range in Yunnan at elevations of 9-10,000 feet above the sea. The nearest ally of D. cinerascens is the North Indian species D. tiliaefolium, G. Don, a species of which we have as yet seen no Chinese example. The record of | D. tiliaefolium as a native of China has been made in the Aprit-JunE, 1919, * “Plantae Wilsonianae” (pars iv. p. 104); but the plant so named appears to Mr. Hutchinson to be D. cinerascens or some nearly allied species, rather than true D. tiliae- folium, which has in India been associated with D. nutans, Wall., and D. argenteum, Wall., but is considered by Mr. Hutchinson to be distinct from both. From D. tiliae- folium, as thus restricted, Mr. Hutchinson separates D. cinerascens by its shorter petioles, more rounded leaflets, persistent stipules and usually quite simple pilose racemes. D. cinerascens appears to have been first raised in Europe from Chinese seeds by the late Mr. M. L. de Vilmorin in 1896. It was presented to the Kew collection by him in 1907, and has proved to be quite hardy, being now a bush three to four feet high. It does not flower until late in the year, usually in October, and while this adds to its value in places where the climate is sufficiently dry and sunny to enable the flowers to develop fully, in a locality like Kew they are apt to decay prematurely through lack of sunshine and excessive humidity. For the same reason seed can rarely ripen, and the plant must be increased by late summer cuttings. The material for our plate we owe to Miss Willmott, in whose collection at Warley Place plants raised from Chinese seed collected by Mr. E. H. Wilson have grown well.

Jahrb. vol. xviii. p. 184.—S. A. Skan, This variety of the widely distributed Ipomoea Pes- tigridis is a new introduction to cultivation. The Kew plant which furnished the material for the figure was raised from seeds received in February, 1917, from Major Howard of Richmond, Surrey, who collected them, and also those of J. dasysperma, Jacq., figured at t. 8788 of-this work, at Kilimatinde in the district of Ugogo, East Tropical Africa, near the railway connecting Daressalam with Tabora. It had previously been found Aprit-JuNE, 1919, in other localities of the territory known as German East Africa; it is also recorded from Somaliland and British East Africa. Grown ina warm house, it flowered while still quite a small plant in April, 1918, and, being an annual, has since died. Typical /. Pes-tigridis ranges throughout India, where it is said to be common, growing in sandy soils; it also occurs in Ceylon, the Malay Peninsula, Malay Islands, Polynesia, China, Mauritius, and in many localities in Tropical East Africa, extending from Kordofan in the north to the Zambesi in the south ; it is represented in Angola by the variety strigosa, Hallier - f. Though of little merit as a garden plant it has appeared in cultivation from time to time, and is recorded as having been first introduced in 1732, the year of publication of Dillenius’s Hortus Elthamensis, in which work (t. 318, fig. 411) it is figured as Volubilis zeylanica, Pes-tigrinus dicta, Tt is also figured in Rheede’s Hortus Malabaricus, vol. xi. t. 59, under the name of Pulli-Schovadi. This Ipomoea belongs to the section Cephalanthae, the species of which usually have rather small flowers arranged in dense bracteate heads, with alee herbaceous sepals more or less resembling the racts. Description.—Herb, annual, everywhere densely beset with long yellow stiff hairs. Stem twining, slender, 6 ft. long or longer.

H. WricHrt. The Disporum now figured is a native of Western Hupeh, where it was first met with by Mr. E. H. Wilson. The plant from which our plate has been prepared flowered in 1917 in the collection of Miss E. A. Willmott, Warley Place, where seeds obtained by Wilson had been received from the Arnold Arboretum. Only one of these seeds, we learn from Miss Wilmott, germinated in her garden. The resulting plant throve well in good sandy loam in a sheltered and partially shaded border with a south-western exposure. A few flowers only were produced during the first season after planting out; since then, however, the plant has flowered freely each year and has ripened seeds well, thus admitting of ready propagation. Care has, however, to be taken to protect the ripening fruits against attack by birds. The genus Disporum was based by Salisbury in 1812 on a Chinese plant, Disporum pullum, which had been already de- Aprit-Jounz, 1919, scribed at t. 916 of the “ Botanical Magazine’ as Uvularia chinensis, Ker-Gawl., and the plant now figured, though it differs sufficiently from the original type of D. pullum to deserve a separate plate, hardly merits, in the present state of our knowledge, the status of a distinct species. Sir Joseph Hooker has referred in the “ Flora of British India’ to the difficulty met with in the discrimination, from herbarium material alone, of the various forms that occur in the genus Disporum. In the case of those forms generally included in D. pullum this difficulty is especially great, and this species, as now understood, contains a number of more or less distinct states differing from each other in the width and degree of pubescence of the leaves, the length of the peduncle, the size of the flower, and the colour of the perianth-segments which varies from white to deep-purple. In the form here figured there is another marked distinction; the perianth- segments, instead of being straight, at length spread stellately towards their tips. For this reason it is now provisionally accorded the rank of a distinct variety, whose name, brunnea, is derived from the circumstance that these segments are of the purplish-brown colour indicated at n. 72 of the “Code des Couleurs ”’ of Messrs. Klincksieck and Valette. Description.—Herb, with a glabrous, branching stem. Leaves lanceolate, acuminate, 2} in. long, 2-2 in, wide, rounded at the base, glabrous above, puberulous beneath and along the margin ; lateral nerves 7-9 on each side the midrib, 2 sometimes 8 of them resembling the central nerve ; petiole sheathing, 2 in, long.

The red Belvidere, also termed the Summer Cypress or Mock Cypress, here figured, is generally accepted as a cultivated condition of Kochia scoparia, Schrad., a Chenopodiaceous plant which extends from temperate JULY-SEPTEMBER, 1919. Asia westward through central and south-western Russia to Hungary. Throughout Germany as far as the Nether- lands and from Central Europe southwards into the Balkan peninsula, Italy and southern France, it also occurs not infrequently as an alien. The name scoparia, long associated with the species, reflects the fact that throughout southern Europe the dry plant is used for making brooms. The genuine Kochia scoparia has been known in English gardens at least since the close of the sixteenth century; it was figured by Gerarde in 1597 as the Bushie or Besome Tode-flax, but he was already acquainted with the popular Italian name Belvidere, which during the seventeenth century appears to have been the term mostly used in English and French gardens. It is clear from Gerarde’s account that the form of the plant known to him did not change in colour from green to red during the autumn, and, indeed, there is no evidence that during the next three centuries any form of K. scoparia exhibiting this phenomenon was known to gardeners. Nor is there any indication that during the sixteenth and seventeenth centuries the form of the Belvidere with narrower leaves figured in our plate was in cultivation in this country. We do not till 1759 find any evidence that suggests the existence of K. scoparia, forma trichophila, in British gardens. This evidence comes from Scotland, and the seed of the narrow-leaved form appears to have arrived there from Holland as Belvidere, under which name it appears in a Haarlem seed-list of 1754. We learn from Miller’s Gardeners’ Dictionary” of 1768 that the narrow- leaved form was in English gardens, but we find no allusion to any save a green Belvidere throughout the eighteenth century. With the establishment of the form with nearly filiform leaves just after the middle of that century, the cultivation of the true K. scoparia appears to have been abandoned. During the later half of the nineteenth century the same became very nearly the case as regards the green narrow-leaved form, its culti- vation being continued only in large establishments like that at Kew. At the close of the century, however, interest in this old-fashioned plant became resuscitated owing to the discovery in or shortly before 1898 of the red Belvidere, which we now figure. In that year a farmer from Alleghany, Pennsylvania, visiting Riverton, New Jersey, handed to Mr. J. W. E. Tracy some seed of this plant with the information that it had been collected from a wild specimen found growing in the woods near Alleghany. The seed was made over to Mr. Henry A. Dreer, who grew it, but did not, however, take the plant_ up. In the following year seed was made over to Mr. Burpee who gave the plant a trial, and placed it in his catalogue for the first time in 1900. Mr. A. J. Pieters, of Washington, to whom horticulture is obliged for this information, remarked in 1906 that after having grown the plant for four years, he had found it constant as regards the change of colour which is its most striking characteristic, but that it is apt, when checked in its growth, to revert to the opener habit which marks the true K. scoparia. It is interesting to note that shortly after the record of this experience by Mr. Pieters, Professor Beck was in a position to describe for the first time in Reichenbach’s “‘Icones” (vol. xxiv. p. 154: 1908) a blood-red wild form as K. scoparia, forma sanguinea. For the introduction of the red Belvidere with filiform leaves to this country we are indebted to Messrs. Cannell and Sons, Swanley, who first brought it to notice in the autumn of 1901. Although the fact is not on record, it is probable that their seed may have come from the United States. The red Belvidere is now somewhat extensively used as a summer bedding plant in gardens, a purpose for which it is well suited. It comes true to seed, and the change in colour from bright green to magenta red takes place somewhat suddenly in autumn. The change appears to mark a stage in ripening, and to be unconnected with the climatic con- ditions encountered by the plant whether in this country or in North America. Descrietion.—Herb, annual, polygamous, much branched from the base, very leafy; crown globose, oblong or conic-pyramidal, 14-5 ft. in height ; branches and branchlets virgate, erect, at first thinly pubescent, soon nearly glabrous, though often laxly woolly towards the top and especially at the nodes. Leaves narrow linear or the uppermost nearly filiform, acute, the longest over din. long, Lin. or less wide, glabrous or the uppermost somewhat ciliate, all white-punctate. Flowers in threes or pairs, or solitary, sessile in the axils of the upper leaves, often surrounded at the base with loose wool, some female, some 2-sexual. Perianth urceolate, 5-lobed, membranous, the female rather depressed, glabrous except the lobes, which are ciliolate, inflexed and hood-like, somewhat apiculate and traversed along the back by a green blunt keel, when fipe little altered save that the keel is occasionally enlarged in the middle into a thick transverse wing.

The interesting Odontoglosswm now figured is a native of Ecuador, where it was first discovered about eighty years ago by Mr. T. Hartweg, when collecting plants for the Royal Horticultural Society of London. ‘The locality of the original specimens was Mount Paccha, near Loxa, on the western slopes of the Andes opposite the Gulf of Guayaquil. For many years this species, which Lindley had described as Q. cristatum, was only known from the original herbarium specimens, but in 1847 living plants of an Odontoglossum, collected in the Loxa district by Mr. G. Wallis, were sent to the horticultural establishment of Mr. Linden at Brussels; these plants, on flowering, were recognised as identical with Hartweg’s one. At a later date the late Mr. Consul Lehmann JuLy-SEPTEMBER, 1919. obtained other specimens of this species in Ecuador, in the forests of Pacayurcu, above Zaruma, also above Ayabamba and Paccha, at from 4,500-6,800 feet above sea-level. Though never a common species in cultiva- tion, it is usually present in representative collections of Orchidaceous plants. The figure here given has been prepared from an example which flowered in the Royal Botanic Garden, Glasnevin, in March, 1917. This plant, Sir F. Moore informs us, was presented to the Glasnevin collection by Sir Jeremiah Colman, in 1908, who had grown it at Gatton Park as an unnamed Odonto- glossum. The species thrives under the treatment for cool-house orchids, a minimum night temperature of 50° F. in winter, with cool airy conditions in summer. A more slender plant in every way than the familiar O. crispum, Lindl., from New Grenada, O. cristatum makes finer and more delicate roots, so that care should be taken that the potting material is not too coarse. There is at Glasnevin another example of O. cristatum, obtained in 1893 from Mr. Cowan, of Gateacre, which was identified at Kew on its first flowering in 1894. The nearest ally of O. cristatum is O. Hallii, Lindl., another Ecuador Odontoglossum, which has been already figured at t. 6237 of this work. Description.—Herb, epiphytic.
