In 1860 Reichenbach described as Stanhopea costaricensis a Costa Rica orchid which flowered that year with Consul Schiller at Hamburg. The plant so named was subsequently lost and the species was known only from the original diagnosis. Towards the close of 1915 Mr. C. H. Lankester sent to Kew from Cachi in Costa Rica some interesting orchids collected by himself. One of these is a Stanhopea from moist and cool localities 4000 feet above sea-level, which flowered in July, 1916. It thrives, like other species of the genus, when grown JanuaRyY—Marcu, 1920, ina teak basket suspended from the roof of the warm Orchid House, if provided with abundant moisture in summer, and kept dry at the root in winter. This Stanhopea Mr. Rolfe thinks may be the lost species because under the hypochil of the lip there is a curious sac whose presence gives this organ a bigibbous appear- ance. This sac suggests greater affinity between our plant and the Peruvian S. graveolens, Lindl., than S. Wardii, Lodd., with which Reichenbach compared S. costaricensis, There are not many species of Stanhopea in Costa Rica, and there are few in the genus which have this sac. Either there are two species in Costa Rica with this sac, or our plant is identical with the Costa Rica Stanhopea flowered by Mr. Schiller at Hamburg in 1860. The original diagnosis does not mention the coloration or the dimensions of the flowers, and it is safest to identify provisionally the plant now figured with the one Reichenbach had in view. In our plant the sepals are buff-yellow with light red somewhat ring-like spots and with smaller spots on the petals and the lip, the latter organ having a pair of dark red ocular patches on the sides of the hypochil. Description.—Herb, epiphytic; pseudobulbs clustered, wide ovoid, slightly angled, olive-green, 14-13 in. long, 1!~13 in. wide, clothed with ovate-lanceolate firm sheaths, 1-foliate.

Flowers large, showy, pale yellow with reddish-brown spots. Sepals somewhat connivent,about 8 in. long, the posterior elliptic-oblong, blunt, concave, the lateral ovate, blunt, deep concave. Petals revolute, oblong, blunt, with very wavy margin, about 2 in. long. Lip fleshy, deeply 4-lobed, about 3 in. long ; hypochil obovate-panduriform, keeled at the side, invaginate below, with a rounded mouth and an almost occluded canal; mesochil deeply 2-partite with falcately incurved acuminate arms; epichil jointed, ovate, rather blunt, convex.

Rhododendron ledoides is a charming plant, with the habit of a Ledum, which belongs to a group of forms, of which some fifteen are now known, spoken of as the Cephalanthum series of Rhododendrons. Nearly all of the members of this series have been discovered by Mr. George Forrest and Mr. Kingdon Ward. The headquarters of the group are at very high altitudes on the ridges which constitute the Tibeto-Yunnan frontier. BR. ledoides was met with by Mr. Forrest in 1913, at about 13,000 feet above sea-level, on the mountains to the - north-east of the Yangtze bend, in Lat. 27° 45’ N., _ Janvary-Marca, 1920. where it occurs as a small shrub, two feet high, in open stony places. Seed received from Mr. Forrest was sown in spring, 1914, by Mr. J. C. Williams of Caerhays Castle, Cornwall, who also shared some with Kew. The plants raised by Mr. Williams, to whom we are indebted for the material for our figure, flowered with him in 1917. The flowers, Mr. Williams finds, range from pink to white, and those that at first are flushed with pink are apt to fade to white. The plant is not difficult to raise, but, as is the case with very many species in this genus, there is much difference between the truss of a well-grown plant such as the one figured, and that of a badly grown one. Descriprion.— Shrublet 2-2} ft. high, fastigiately or rather loosely branched, young shoots clothed with loose brown scales and short stiff hairs ; buds narrow- ovoid, rather acute, their scales densely scaly and weakly ciliate.

Bran. The North American Winterberry, sometimes also known in north-eastern America as the Black Alder, has long been a favourite in English gardens, to which, according to Aiton, it was introduced for the first time in 1736. It is found wild over a wide area on the eastern side of North America, ranging from Nova Scotia and _ January-Marcu, 1920. Wisconsin in the north, to Missouri and Florida in the south. In many parts of this area it is abundant, preferring low and damp or even swampy situations. Jle verticillata is the commonest and best known in gardens of that section in which the leaves are deciduous, of the genus to which our common Holly belongs. Linneus, who named it Prinos verticillatus in 1753, and most of the older writers, indeed regarded these Hollies which are not evergreen as constituting a genus apart. The modern view, based on the identity in floral structure in the two groups, is that Prinos is only a subgenus or section of //ex, though it is to be noted that the leaves in Prinos, besides being deciduous, differ also in their mem- branous texture from those of the A quifolium section, to which the true Holly belongs. In Prinos, moreover, the parts of the female flower, though similar in shape and arrangement, are usually more numerous than in Aqui- jolium. The nearest ally of J. verticillata is I. laevigata, A. Gray, the Smooth Winterberry of American writers, which occurs in the same natural habitats, but can be readily distinguished from the common Winterberry by its leaves, which are nearly or quite glabrous, by the longer pedicels of its male flowers, and by its entire calyx- lobes, which are not ciliate. Like many other North American trees and shrubs that affect swamps and damp places in a state of nature, J. verticillata thrives best in this country in good well-drained loamy or peaty soil. There are few more beautiful fruit-bearing shrubs when it carries an abudant crop of its bright red drupes. But to secure this result thorough ripening of its wood is essential, and for this reason the plants must be given a _ position fully exposed to the south. J. verticillata ean be propagated either by seed or by cuttings, the latter being made of leafy shoots, in July. The fruit-bearing twig figured in our plate was supplied by Messrs Waterer and Sons of Bagshot in October, 1917, when it happened to be in bearing and in unusual profusion. The male and female flowering twigs were supplied from the Kew collection, where the plant thrives well, but does not always fruit freely. A variety with yellow fruit, which Professor Robinson has distinguished as var. chrysocarpa, is also in cultivation along with other forms that differ from each other in the shape, texture and pubescence of the leaves. Descriprion.—Shrub 8-20 ft. high, usually dioecious ; young shoots glabrous in the typical form, dark brown, sparingly beset with pale lenticels. Leaves deciduous, oval, narrowly obovate, or oblanceolate, acute or acuminate, base cuneate, margin finely and often unevenly serrate or 2-serrate, 13-3} in. long, 3-13 in. wide, glabrous or slightly pubescent above, always pubescent beneath especially near the midrib, strongly reticulate ; petiole }-} in. long. Flowers produced in short-stalked axillary umbels, the males 6 or more in a cluster, the females 1-3 in a cluster. Calyx 5-6-lobed, the lobes ciliate, acute. Corolla rotate, dull white, ;3; in. across; lobes usually 6, occasionally 7-8; rounded, obtuse. Stamens usually 6, occasionally 7-8, alternate with the corolla lobes ; filaments very short; anthers dehiscing longitudinally. Ovary ovoid; cells usually 6, sometimes 7-8; stigma sessile, stellately 6-8-lobed. Frait a scarlet globose or ovoid drupe, usually solitary, occasionally in pairs or threes in each axil, } in. long; stones (pyrenes) compressed, } in. long, 4-6 in each drupe, pale brown, smooth, bitter.

Cornus Kousa, originally found in Japan on the moun- tains of Kiusiu and of Nippon, has a wide distribution in north-eastern Asia, for it has since been discovered in Corea and in China. The plant from which the material for our figure was obtained was received at Kew from the Arnold Arboretum in 1910, where it had been raised from seed collected by Mr. E. H. Wilson in western Hupeh three years previously. Wilson has reported that he found it abundant both north and south of Ichang, at altitudes of from 4000 to 7000 feet, both as a shrub and as a small, flat-topped tree, fifteen to thirty feet in January-Marcu, 1920, height. ‘He has stated that the fruit is edible. This species, along with the evergreen C’. capitata, Wall., of the Himalayas, constitutes the Asiatic subgenus which Lindley recognised as the genus Benthamia. This group is characterised by the large corolla-like involucre and more especially by the coalescence of the fruits into a fleshy strawberry-like mass. This latter feature distin- guishes the two constituent species from (. florida, Linn., figured at t. 8315 of this work, and (. Nuttalli7, Audubon, figured at t. 8311, which together form the subgenus Benthamidia, Spach. These latter two also have a large showy involucre, but in both the fruits remain free and both are confined to North America. (€. Kousa flowers in May and thrives very weli in the British Isles, over the greater part of which it should be quite hardy. It has never suffered from cold at Kew. It likes a deep well-drained, loamy soil and a sunny position. It is less sensitive to injury by late spring frosts than ©. florida is, and when in flower may be described as one of the most beautiful as well as remarkable of hardy shrubs. It varies a good deal as regards the size of the involucre and the Chinese form introduced from Hupeh, which is fig- ured here, has the largest and most striking bracts of any we have seen in cultivation, though among the fine series of specimens from Japan preserved in the Kew her- barium there are some with bracts quite as large as those of this Chinese plant.

The handsome Chinese Rhododendron here described was first met with by the Abbé Soulié in 1893 in the forests of Tongolo and in the vicinity of Ta-chien-lu in Western Szechuan and was characterised two years later, under the name Shododendron lucidum, by the late Mr. Franchet. The author in so doing had overlooked the fact that, forty years earlier, Mr. Nuttall had described a very different Himalayan species under the same name. Five years later, however, having discovered his over- sight, Mr. Franchet substituted for the Chinese plant the January—Marcg, 1920, name £2. vernicosum now employed. A decade later seeds of £. vernicosum were secured by Mr. E. H. Wilson for Messrs J. Veitch and Sons, and the material for our plate came from a plant purchased by Kew from Messrs Veitch in 1908. It has been fully realised in English collections that this is not R. lucidum, Nutt., but this has been counterbalanced by the belief that Soulic’s species is a variety, var. /ucidum, of another Chinese Rhododendron described by Lindley in 1859 as R. Furtunei, T. Moore. The flowers of the true &. Fortune’ differ much from those of the Szechuan plant; they lack the fragrance and do not exhibit the crumpled appearance characteristic of the opening blooms of &. Fortunci. The smaller leaves, unequally rounded at the base, and the shape of the corolla-tube are also distinguishing features. Since the collection of F. vernicosum by Mr. Wilson, the species has been found again by Mr. G. Forrest in North-West Yunnan, where it grows on the borders of pine forests on the eastern flank of the Li-chiang range at about 11,000 feet above sea-level, as a spreading shrub sometimes fifteen feet in height. The species is perfectly hardy at Kew and thrives in peaty soil or sandy loam free from lime. It prefers a position where it is protected from the rays of the mid-day sun. Description.—Shrub of spreading habit, in a wild state up to 15 ft. in height; twigs cylindric, dark brown, glabrous, somewhat polished when dry, + in. thick in their second season.

San. This attractive heath, a new species of the small] section Lurysteygia of the subgenus Chlamydanthe, as defined by Guthrie and Bolus in the Flora Capensis, was discovered by the late Professor H. H. W. Pearson on the Cederberg Range in the Clanwilliam Division, and seeds _Janvary—Marcu, 1920. were sent by him to Kew from the National Botanic Garden, Kirstenbosch, in 1915. One of the plants raised from these seeds has now reached a height of about eighteen inches and fiowered in a greenhouse in January, 1919. Its flowers are rather large and effective, and should the plant prove floriferous it will be a welcome addition to the number of winter-flowering heaths in cultivation. Among the Cape species of Lica already described, now nearly 500, /. Haroldiana (named after its discoverer, who is also commemorated in the genus by F. Pearsoniana, L. Bolus) is clearly most nearly allied to L. nobilis, Guthrie and Bolus, a little-known plant which, like that now described, is found on the Cederberg Range. It may, however, easily be distinguished by the characters mentioned above. /. Monsoniana, Linn., of which the variety exserta, Klotzsch, is figured at t. 1915 of this Magazine as E. Monsoniae, is also an ally, but, particularly when young, its branches are covered with a floccose pubescence, its much shorter leaves are ciliate, and its flowers terminate very short lateral branches arising below the tips of the shoots. £: glauca, Andr., figured at t. 580 of this work, is a pretty species belonging to the same section, but quite distinct. Other Ericas re- corded from the Cederberg Range are /. verecunda, Salisb., EE. Thunbergii, Montin, and £. inflata, Thunb., all ob- viously different from /. Haroldiana, though F. inflata resembles it in habit, umbellate inflorescence, and some- what in the corolla which, however, is smaller, while the calyx and bracts are quite dissimilar. /. /aroldiana seems to be quite happy and is making good growth, under the cool greenhouse treatment accorded the other members of this genus from 8. Africa. Description.—Shrub 1} ft. high or somewhat taller, erect, much branched ; twigs erect, rigid, densely leafy, pale brown, glabrous.

Hurcurnson, The Primula here figured is a native of North-west Yunnan where it was first discovered by Mr. F. Kingdon Ward in June, 1913, on precipices above a glacier two days’ journey to the west of Atuntsu, at an altitude of 11,000 feet above the sea. Mr. Ward notes that the species, which has been described by Professor Bayley Balfour and himself as P. pulvinata, occurs naturally in large tufts, and Professor Balfour speaks of it in culti- vation in the Royal Botanic Garden, Edinburgh, as a dainty cushion-plant. The figure now published has been prepared from a living plant kindly forwarded for the purpose by Professor Balfour. It was raised in the Edinburgh garden from the seeds supplied by Messrs. Bees, Limited, to whom they had been communicated from Yunnan by Mr. Ward. At Edinburgh where the _ January-Marcu, 1920, species has been grown in pots as well as planted out under glass in a house devoted to rock-plants, P. pulvinata has proved easy to cultivate at all stages. It does not appear to be fastidious as to soil; a good loam with a liberal supply of broken limestone or crushed potsherds and sand gives satisfactory results. It is not yet possible to say from experience that it will prove entirely hardy out of doors, but in the cold greenhouse it has withstood fifteen degrees of frost without suffering damage. Being evergreen, growth appears to goon during the whole year. Mr. Harrow, to whom through Professor Balfour we are indebted for this information, regards it as probable that the best hope for success out of doors will be where the plant is grown in a situation where the water, of which it requires at all seasons a fair amount, can drain away quickly from the collar and roots, At Kew the plant has been accorded the treatment suitable for P. Forrestii with satisfactory results. The great difficulty, as Professor Balfour points out, with the Primulas of this group, and the circumstance that militates against their satis- factory cultivation as garden plants, is winter damp. These species show a crisp type of withering of their leaves, and while they can resist a moderate amount of top-water, cannot live if their withering leaves become sodden. Descriprion.—Herb, forming dense cushions; individual plants dwarf, devoid of mealiness, softly clothed with viscid distinctly stalked glands. Leaves long-petioled, lanceolate, blunt at the tip, gradually narrowed to the base into the winged petiole, up to 23 in. long, over 4 in. wide, with crenulately wavy margin, papery, somewhat bullately veined and glandular-puberulous above, pilose beneath, lateral nerves somewhat raised, about 6 on each side the midrib; petiole about } in. long, 1 in. wide, 1-nerved, towards the base straw- coloured and somewhat translucent.

Coll. Sci. Tokyo, vol, xxxi. 1911).—W. B. Turri. The striking Campanulaceous species now figured was first described by Mr. Nakai in 1909 as a Symphandra. Two years later its author came to the conclusion that it represents a distinct genus which he named //anabusaya. In the work in which this revised view is stated Mr. Nakai does not lay emphasis on the points by which it may be distinguished from Symphandra and, as we have failed to detect any such, we have here employed his original name, S. asiatica. Perhaps the most remarkable feature con- nected with this Corean plant is its geographical isolation. The other species of the genus Symphandra are contined to South-eastern Europe, the Caucasus, Armenia, Lazistan January—Marcu, 1920, and northern Persia, and the species to which the Corean S. asiatica is most closely related is the Candian S. eretica, A.DC., one that has long been known. For the mate- rial from which our plate has been prepared we are indebted to Mr. G. W. E. Loder, who received seed of the species collected by Mr. E. H. Wilson in Corea. This seed was sown in two pots, in March, 1918, and flowered in a cool house in Mr. Loder’s garden at Wakehurst Place, Ardingly, Sussex, during June and July, 1919. One of these pots with seedlings, some of them in flower, was presented to the Kew collection by Mr. Loder and en- abled the figure now supplied to be made. So far the hardiness of the species has not been put to the test of cultivation in the open.

The Rubiaceous genus /avetta is restricted to the Eastern hemisphere, five-sixths of the species being confined to the tropical regions of south-eastern Asia and Africa, the remaining sixth occurring in South Africa. Among the members of the South African group of species one, ?. caffra, Linn. f., an old and long known plant in European collections, has been figured at t. 3580 of this work. The plant now figured is one of the Tropical African species, which is a native of Abyssinia and Uganda, where it grows in the warm zone on the lower slopes of the mountains. This species was first — met with by Mr. Henry Salt during his travels in the JaANUARY—Marcu, 1920. interior of Abyssinia in 1809-10 on behalf of the British Government. Dr. Robert Brown, who identified the plants collected by Salt, named this one P. congesta. Un- fortunately no description of the species was published at the time, and when the plant was met with again by Dr. Riippell, who found it on the way from Halei to Tem- ben in Abyssinia, it was in 1837 for the first time de- scribed by Fresenius from Riippell’s specimens as P. abys- sinica. In 1916 the plant was sent to Kew from Kam- paia in Uganda, where it is also wild, as a species of Clerodendron; for its introduction to ¢ultivatiom we are indebted to the Agricultural Department of the Govern- ment of Uganda. Nearly three years later it flowered in February, 1919, in a tropical house at Kew, and thus provided material for the preparation of our plate. It has thriven well under the conditions suitable for the Indian species of /zora and Pavetta, and had reached a height of six feet before it flowered. As in the case of the Indian species of Pavetta, the flowers of P. abyssinica are very fragrant. Description.—Shrub, 6-8 ft. high; twigs pale grey, villous at the joints. Leaves obovate-elliptic, bluntly acuminate, cuneate at the base, usually about 6 in. long by 13 in. wide, but sometimes 9-10 in. long by 4 in. across, margin undulate, thinly papery, at first setulose but soon glabrous above, laxly hairy, especially on the nerves beneath; lateral nerves 12-14 on each side of the midrib which they leave at a wide angle, pale on both surfaces and raised beneath; petiole usually about ? in. long, but in large leaves 11 in. long, laxly hairy; stipules almost membranous, caducous, 2 in. long, long acuminate, densely villous on the inner ‘face.

The species here figured, P. punctulata, may be included among those worthy of a place in a good collection, even if its claims on aesthetic grounds are not of a high standard, owing to its rarity. To a place in the pages of this Magazine it is fully entitled because of its considerable botanical interest. It seems to be unique in the genus Pleurothallis for the glaucous hue of the leaves, due to a dense coating of greyish-white farina. It is also curious on account of a characteristic twist at the base of the petiole, the effect of which is to bring the solitary flower opposite the under-surface of the leaf. This feature was alluded to when the species was first described by Mr. Rolfe, now thirty years ago, but was then cautiously adverted to as possibly an accidental circumstance. The experience of a generation January—Marcu, 1920. : shows that the character is as constant as it is peculiar. There are other features of an anomaious nature which tend to render the affinity of our plant doubtful. While it is, as Mr. Rolfe points out, most comparable with the Colombian P. inflata, Rolfe, a species certainly referable to the group Macrophyllac-Fasciculatae as defined by the late Professor Lindley, the plant figured produces a soli- tary flower from a large spathe like that in the natural section Spathaceae. Yet it differs essentially from the true members of that section, in all of which the flowers are disposed in many-flowered racemes. The history of P. punctulata is simple, so far as it goes. The species flowered for the first time in cultivation in December, 1888, with Messrs James Veitch and Sons, Chelsea, and was then submitted to Kew for identification with the information that it had been imported, as a solitary plant, from New Granada, three years before. Shortly thereafter, the plant passed into the collection of Mr. R. I. Measures of Camberwell, with whom it flowered in December, 1802. No other plant of the species is ‘known to have been imported, and no wild specimen has been met with in herbarium collections, so that the precise habitat of P. punctulata in Colombia is still uncertain. In, February, 1908, a small portion of the original plant, secured by division, was presented to the Kew Collection. This plant has thriven well in a cool house under the conditions suitable for species of Masdevallia, and came into flower in November, 1918, when our figure was made.

Wilson in Western Szechuan in July, 1903, and was collected by him again near Ta-chien-lu in 1904. According to the Plantae Wilsonianae it was found by the same collector in 1908 and in 1910 in various other JaNUARY-MarcH, 1920. localities, all in Western Szechuan. The shrub, which attains a height of six to nine feet and is notable on account of its sometimes red and at other times orange glandular fruits, occurs in woodlands and thickets up to an elevation of 9400 feet above sea-level. The plant was first introduced to cultivation, from Mr. Wilson’s earlier seeds, by Messrs James Veitch and Sons, and in 1915 a flowering branch stated to be of Chinese origin and to represent one of Mr. Wilson’s plants (958a) was submitted to Kew for identification by Colonel S. R. Clarke of Borde Hill, Cuckfield, Sussex. The spray sent was readily identified with Mr. Wilson’s plant of the 1903 collection (3759) and Miss Jesson, who established this fact, regarded it as a very distinct variety of Ribes Maximowiczii, Bat., a species discovered by Mr. Potanin in Eastern Kansu, which is characterised by its short extremely compact fruiting racemes, with the individual fruits closely covered with coarse bristles. The affinity between the two shrubs is indeed extremely close, but the additional material now available shows that it is more _ Satisfactory to regard Miss. Jesson’s variety as a separate species, readily distinguished by its much elongated inflorescences with more numerous flowers and especially by the much shorter and less plentiful glandular bristles which cover the berries. Professor Janczewski, who has included the Szechuan plant now described in the species from Kansu which Batalin named 2. Maximowiczii, only knew the latter in the fruiting condition, and, although he Placed it in the section Berisia, was disposed to believe that it may really belong to his section Parilla. There seems now no doubt, however, that the arrangement actually adopted by Janczewski is correct, for the plant now figured as RF. Jessoniae and named in compliment to the lady who first indicated the differences between it and the plant from Kansu, is certainly a member of the section erisia, which. differs from Parilla in having erect in place of pendent racemes, in having no ovules in _ the female flowers and in having no pollen in the reduced anthers of the male flowers: in Parilla the male flowers have sterile pollen and the female have sterile ovules. The material for our plate has been derived, as regards the male inflorescence, from a plant in the collection at Kew; for the female inflorescence and the fruit we are indebted to the kindness of Mrs. Berkeley of Spetchley Park, Worcester, in whose garden they were produced. It is to be noted that as they ripen in this country the fruits are of a pale rusty yellow colour, not orange or red as they are in Szechuan. At Kew the shrub is perfectly hardy and thrives well in loamy soil. It can be increased readily by cuttings. The section Berisia to which it belongs contains seventeen species, most of them Chinese, though it includes also the well-known &. alpi- num, Linn., a native of Europe and Northern Asia. Description.—Shrub, 6-9 ft. high, branching freely, unarmed, dioecious ; twigs of the first season thinly pubescent and sparingly glandular-setulose ; bark of older twigs brown or tawny, cracking longitudinally.

There are, however, many differences _ Aprit-JuneE, 1920, between the species described by Mr. Franchet and that now described as R. serotinum. The latter is of long and straggling growth, a feature so marked in one of the two healthy plants grown in the Himalayan House at Kew, that it admits of being trained up one of the pillars which support the roof. This character, the fact that the leaves are unequally cordate at the base, and the circumstance that the corolla outside is beset with many bottle-shaped glands are marks that at once distinguish RR. serotinum from R. decorum. From R. Fortunei, Lindl., another close ally and a member of the same natural group, . serotinum differs especially by its hairy filaments. From both species mentioned £. serotinum may be distinguished by its blotched corolla, an unusual feature in the group to which all three belong. Out of doors /. serotinum was grown for a number of years in the Rhododendron Dell at Kew, and appeared to be perfectly hardy. But save when in flower it was principally remarkable for its gaunt sparsely branched habit, and when the stem was at last broken off at ground-level during a gale, the plant was not replaced. If space can be found for it in a collection it nevertheless is not unworthy of a place, for the flowers are handsome and delightfully fragrant, and they exhibit one feature that cannot but appeal to growers of Rhododendrons. Even under the protection of the Himalayan House the species does not begin to flower until well into August, and continues to produce blossoms from then till the end of October. In the Kew plants the leaves exhibit three or four parallel impressions on each side of the midrib, perhaps the consequence of their disposition in the bud stage. DEscriPTion.—Shrub, up to 10 ft. high ; branches long and lax; other twigs yellowish-brown, smooth, polished ; young shoots green, polished, marked with minute pale lenticels.

Chron, 1915, vol. lviii. p. 53, fig. 18; Rolfe in Orch, Rey. 1915, pp. 247, 256.—R. A. Roure. For the introduction to English collections of the remarkable New Guinea species of Bulbophyllum now figured, orchid growers are indebted to Messrs. Sander and Sons, St. Albans, by whom it was publicly exhibited in July, 1915, under the name B. Balfourianum. The plant in question thereafter was added to the collection of Mr. H. T. Pitt, Rosslyn, Stamford Hill, to whose courtesy we are indebted for the material for our plate which was kindly supplied when the plant was in blossom — in June, 1919. The name under which the species has thus found its way into cultivation is not, however, one ApriL-JuNE, 1920. that can be sustained since the species was discovered during the second Lorentz Expedition to New Guinea, was afterwards in cultivation in the Buitenzorg Botanic Garden, and was there adequately described as B. macro- bulbum by Mr. J. J. Smith. When publishing this account, Mr. Smith referred the species to the section Sestochilos, but it has since been treated by Mr. Schlechter, who met with the plant again in North-eastern New Guinea, as the type of a distinct section, Macrobulbum. The species is remarkable for its very glaucous leaves, a character wherein it agrees with the allied B. Fletcher- ianum, figured at t. 8600 of this work as Cirrhopetalum Fletcherianum, Rolfe. The individual flowers bear some resemblance to those of Cymbidium Huttonii, Lindl, figured in this magazine at t. 5676. In cultivation it calls for the tropical treatment suitable for other species of the genus.

Racemes axillary, much contracted, clustered at the bases of the pseudobulbs, 4-5-flowered ; bracts wide ovate, concave, $—-1in. long, acuminate and recurved at the tip; pedicels about 2 in. long. Flowers large, fleshy, odour unpleasant, yellowish-white with purple lines and blotches, the lip and the bases of the petals blood-red. Sepals about 13-13 in. long; posterior obliquely erect, ovate, very acuminate, concave; lateral obliquely ovate, foliately recurved, acuminate.

Bran. floheria populnea was originally discovered by Mr. C. Fraser in 1825, and again by Mr. R. Cunningham in 1833. Upon their specimens Mr. A. Cunningham founded the genus in 1839, adapting for it the native name for the tree, “ houhere’’ or “ hoihere.”’ It occurs in both the North and South Islands of New Zealand. The genus is closely allied to Plagianthus, which differs from //oheria in the often unisexual flowers, the linear decurrent stigmas and the solitary carpels. 7. populnea, like so many New Zealand trees, is extremely variable, and whilst most authorities follow Sir J. D. Hooker in regarding the various forms as belonging to one species, others look upon them as constituting three or four APRIL-JUNE, 1920, closely allied species. The differences are chiefly in the size and shape of the leaves, in the size of the flowers, and in the number of flowers in each fascicle. Mr. Kirk observes that the transition of one variety to another is so gradual that it is impossible to define lines of separation. The form now figured we regard as most nearly approaching Hooker’s var. lanceolata, which differs from his var. vulgaris in its lanceolate leaves and smaller, fewer flowers. In var. vulgaris some leaves are as much as five inches long by two and a half inches wide. Ina third variety (angustifolia, Hook. f.) many leaves are only an inch iong by one-third of an inch wide. The most curious exhibition of heterophylly is, however, seen in occasional basal and apparently sterile shoots which bear leaves shaped like those of Hawthorn, many of them only from a quarter to half an inch long. Near London the Hoheria needs greenhouse or at least wall protection. It is hardy further south and along most of our western seaboard. The material for our figure was kindly furnished by Mr. R. Windsor Rickards, Usk Priory, Monmouth, to whom it had been given by Mr. H. A. Tipping, Mountain House, Chepstow, in whose garden it flowers in August. It is also cultivated in the gardens of Cornwall, Devon, Scilly Isles, etc., where it is one of the most graceful and attractive of Jate-flowering trees. It thrives in loamy soil and can be propagated by cuttings. Description.—Tree of small size, 10-80 ft. high, and graceful habit, or a shrub ; young shoots covered with a grey stellate pubescence. Leaves alternate, persistent, lanceolate to ovate-lanceolate, acuminate at the apex, cuneate at the base, coarsely and irregularly dentate, teeth slender; the blade 1-4 in. long, 3-1} in. wide, glabrous or with very scattered stellate pubescence beneath, rich lustrous green above ; petiole }-} in. long, stellately pubescent.

The handsome /ris here figured is a native of Turkes- tan, for the introduction of which horticulture is indebted to Mr. C. G. van Tubergen, the younger. Its earliest appearance in cultivation in this country dates from 1913, in which year rhizomes reached the garden of Mr. W. R. Dykes at Godalming, where it flowered for the first time in 1916, and whence the material for the present plate was contributed by Mr. Dykes in May, 1919. When describing the species on the occasion of its first making blossom, Mr. Dykes pointed out that it is a member of the section /egeliana, in foliage closely resembling /. Korolkowii, Reg., from Turkestan (figured at t. 7025 of this work), and /. stolonifera, Maxim., from Aprit-JUNE, 1920. : Kokan, two well-known species of the same group, with rootstocks that spread even more rapidly by stolons than the former, though hardly to be distinguished, when in a dormant condition, from those of the latter. This new /ris Mr. Dykes has dedicated to the Messrs. Hoog, nephews of its introducer, and now the heads of the famous establishment at Haarlem whence it was received by him. Like other members of the same section as I. Hoogiana, Mr. Dykes finds that its rhizomes, if they are to remain firm and plump, should not be taken up before the middle of July. One of the more pronounced features of this /ris is the uniform colouring of all parts of the flower, with the exception of the rich golden- yellow beard. The general colour is lavender in the fully opened flower, though the shade appears to vary slightly, and in his original account of the plant Mr. Dykes states, on the authority of Mr. Hoog, that white- flowered specimens occur in the original stock. Description.—Herb with the rhizome emitting numerous stolons which are often of considerable length. Leaves ensate, slightly curved, somewhat blunt, 14-18 in. long, up to ? in. wide, glaucous-green, smooth. Stem about 20 in. high, 2-3-flowered at the top. Spathes herbaceous, green except at the tip and along the upper portion of the membranous margin where they are flushed with purple, sharply keeled, 24-3} in. Pedicels very short. Perianth-tube green, streaked with purple, about 1} in. long, reaching the top of the spathe ; outer segments with a reflexed rounded-obovate quite blunt, uniformly clear lavender- violet limb, 1} in. long, 1} in. wide, and with a wide cuneate claw 1} in. long, of a paler lavender, indistinctly veined at the sides, beard copious, golden yellow, extending almost for 1} in. somewhat beyond the claw on to the limb, where it becomes thinner and ends abruptly ; inner segments erect, with an obovate somewhat acute limb gradually narrowed downwards to a short rather narrow claw, including the claw over 3 in. long, 1} in. wide, uniform in colour with the outer segments, beard scanty, golden yellow, extending about 1 in. Anthers slightly longer than the filaments, pale in colour, with whitish pollen. Ovary oblong, 1-1} in. long; style-arms wide-oblong, lavender; crests with broadly semi-ovate, almost entire lobes. Capsule elongated, narrowed to the tip. Seeds pyriform, brown, rugulose, with a conspicuous whitish aril.

HuTcHINnson, The Composite genus Venidium, established by Lessing in 1831, includes some five and twenty species, all of them natives of South Africa. It is closely allied to Aretotis, a genus recognised by Linnaeus, and has, in fact, been united therewith by authorities so competent as Hoffmann and Beauverd. Bentham, however, relying on characters derived from the achenes and the pappus, has followed Lessing and Decandolle, and Mr. Hutchinson, ‘who has prepared the description that precedes this note, finds himself, after a critical scrutiny of the species of this and other allied genera, able to confirm the validity of the conclusions arrived at by Bentham. The absence Aprit-June, 1920. or extreme reduction of the pappus in Venidium renders its separation from Arctotis as easy as it is essential. The beautiful species now figured shares with a number of other Compositae that possess large and showy flower- heads the popular name “Gouws bloem.” It has been determined, from the original description, to be the species named by Decandolle V. macrocephalum, which would appear to be extremely rare, for the only previous record of its collection is that by Drége, who found it in South-west Africa, between Kaus and the Orange River. The plant figured was raised at Kew from seed sent from Pretoria by Dr. I. B. Pole Evans in the spring of 1918. It flowered in August of the same year, but unfortunately failed to ripen its seeds at Kew. Description.—Herb with a simple annual 1-flowered stem, 1} ft. high, sparingly pubescent throughout with many-celled hairs, sparsely leafy low down, Leaves nearest the ground long petioled, lyrately pinnately lobed, 6-8 in. long, those higher up sessile, elliptic or oblong-elliptic, rounded or subtruncate at the base, blunt at the tip, 13-2} in. long, 2-1} in. wide, papery, lobed or entire, pilose, especially along the nerves beneath, 3-nerved at the base with the nerves ascending and raised beneath ; petiole of the lower leaves up to 3 in. long.

The Myrtaceous genus Metrosideros is widely distributed throughout Polynesia and is well represented in New Zealand. The species now figured, J. collina, though not one of the New Zealand members of the genus, is most nearly allied to J/. tomentosa, A. Rich., known in New Zealand as the Christmas Tree and figured at t. 4488 of this work. The history of our plant is some- _ what complicated, a circumstance attributable partly to its very wide distribution, partly to the variability it displays. It was first briefly characterised by Forster Aprit—June, 1920. in 1776 as Leptospermum collinum, from specimens the exact provenance of which is unknown, and was diagnosed by him a second time as Melaleuca aestuosa, from Tahiti material. Later this species was united with the Hawaiian Metrosideros polymorpha of Gaudichaud, now reported from many other Polynesian groups. Recently, however, Mr. J. F. Rock, Government Botanist of the Sandwich Islands, after a careful study of the Hawaiian Metrosideros, has reached the conclusion that M. poly- morpha includes five species, four of these being endemic in the group, while the fifth is the widespread MW. collina. But Mr. Rock finds further that in the Sandwich Islands M. collina itself includes eleven recognisable varieties, nine of which are endemic, while the remaining two, var. glaberrima and var. incana, are distributed. The form recognised as var. incana is, however, at once the Linnaean Melaleuca villosa and the original Leptospermum collinum of Forster which we now figure: This particular form extends from Lord Howe Island and New Caledonia eastward to Pitcairn Island and Tahiti and northward to Hawaii. For the introduction of M. collina to European gardens, horticulture is indebted to Major A. A. Dorrien-Smith, from whose garden at Tresco Abbey, Isles of Scilly,.came the material for our figure. To Tresco Major Dorrien-Smith brought his plant from ‘Wellington, New Zealand, whither it had been introduced from Sunday Island in the Kermadec Group by Mr. R. B. Oliver. It thrives satisfactorily in the Scilly Islands, where it flowered in June, 1918, and may prove hardy in other especially favoured situations in the south-west of England and Ireland. Description.—T ree, up to 60 ft. high, or at times a shrub; branches terete, at first usually hairy, ultimately becoming glabrous. Leaves opposite, shortly stalked, leathery, obovate, wide elliptic or nearly orbicular, blunt at the apex, cuneate or rounded at the base, villous or glabrous, 1}-2} in. long, 3-1} in. wide ; veins many, parallel; petiole 1-2 in. long.

The Chinese lily now figured is a member of the Martagon group of the genus Lilium, raised by Major F. C. Stern, at Highdown, Goring-by-Sea, Sussex, from seeds received by him from China in 1915, from Mr. Reginald Farrer, with the indication that this — particular batch consisted of ‘‘a mixed lot of poor seed Aprit-JuneE, 1920. of undecipherable small lilies.” Whatever the other components of this seed-packet may prove to be, it is interesting to know that of the species included therein one proves to be new to cultivation and to science, and possesses intrinsic merits that justify its dedication to the distinguished traveller and cultivator to whose efforts its introduction to our gardens is primarily due. In the Martagon group, our plant, which has been figured from material placed at our service by Major Stern, is clearly a near ally of LZ. Duchartrei, Franch., figured at t. 8072 of this work. The features which especially characterise L. /urreri are its linear-lanceolate cauline leaves which are disposed throughout the greater part of the stem, and its relatively small flowers whose revolute perianth-segments are white with dark purple spots. In the lower portion of the flower these segments converge to form a tube under half an inchin length. The flowers are very strongly but pleasantly scented. Major Stern informs us that very little seed of this species was received. This seed was sown in March, 1915, in ordinary garden soil which, at Highdown, is particularly full of lime. The plants raised have proved quite hardy, and flowered with Major Stern for the first time in 1917, beginning in July and continuing in flower till August. They appear to thrive equally well in garden plots and in pots, calling for a fairly dry situation and good drainage. The plants fruit very freely, and the seeds ripen satisfactorily in the open air. The material for our plate was received from Major Stern in July, 1919, and in all the specimens so far communicated the inflorescence has been either strictly umbellate or re- duced to a single terminal flower. A character which appears to be variable in L. Farreri is the presence of tufts of white hairs at the nodes. In the example figured these were very marked, but in other specimens subsequently received the leaves and stems are quite glabrous, so that in this respect L. arreri shares a peculiarity which, as Professor Bayley Balfour has pointed out, is well seen in the Nomocharis group, where hairs may be present on or absent from the nodes in the same species. There would also seem to be some degree of variation in the size and shape of the capsules, some of those received being larger and narrower than that now | figured and described. Description.—Herb with an undulately creeping horizontal rootstock about zy in. thick, with white naked internodes up to 3 in. long, bulbiferous at the nodes ; young bulbs wide ovoid, acute, over 4 in. long and nearly as thick, loosely or closely clothed with a few broad thick scales. Stem erect, 2}-2? ft. high, firm, green, below marked with longitudinal lines of bullate cells, some- times floccose with white hairs in the axils of the leaves and bracts, sometimes quite glabrous. Leaves many, scattered throughout the whole length of the stem, linear-oblanceolate, acute, gradually narrowed to the base, 34 in. long, over 1 in. wide, with 3-5 main-veins, glabrous on both surfaces and with a marginal line of bullate cells. Flowers terminal, solitary or aggregated in a loose 6-flowered umbel, very fragrant; bracts (floral leaves) verticillate, narrow elliptic-oblanceolate, acute, gradually narrowed to the base, about 1 in. long, over } in. wide, glabrous; pedicels 3-6 in. long, sometimes white-floccose, sometimes glabrous at the point of origin of the solitary bracteole which is attached near the middle of the pedicel and resembles the bracts save for being smaller and narrower. Perianth-segments revolute, lanceolate, the outer acute, the inner obtuse, over 2 in. long, nearly } in. wide, white with dark purple blotches in the lower half, forming at the base a green tube less than } in. long, finely pilose at the tip and with a nectarial groove provided with two papillose lines near the base on the upper surface, elsewhere glabrous.

The Chinese Salvia described by the late Mr. Franchet as S. brevilabra was first collected near Ta-chien-lu in Western Szechuan by Pere Soulié and was sent by him in 1890-91 to the Paris Museum. We have not had access to the original type with which Mr. Dunn has identified, from its description, the plant now figured, which was met with in the original locality some fourteen years later by Mr. E. H. Wilson, and was raised from Aprit-JUNE, 1920, Wilson’s seeds by Messrs. James Veitch and Sons in their nursery at Coombe Wood, where it flowered for the first time in 1905, and was then regarded by Mr. Duthie as an undescribed species which he named S. brevilabra owing to his having identified it with a specimen in the Kew herbarium issued as Soulie, n. 97. This latter plant has, however, been described by the late Mr. Leveillé as S. Blinii, and although Dunn has reduced S. Blinii to S. brevilabra, it is not altogether certain that Leveillé’s plant is identical with that of Wilson. The plant which Leveillé had before him differs from the one now figured in having less coarsely toothed leaves, densely covered on the undersurface with a rather short grey pubescence. These features characterise specimens obtained by Mr. Pratt and issued as Pratt, n. 214, which are included in S. brevilabra by Dunn. There are thus certainly two readily distinguishable, if closely allied forms of Salvia to be found growing at elevations of 10-12,000 feet in the neighbourhood of Ta-chien-lu, and under the circumstances it seems desirable to regard them as specifically distinct. Both species are equally closely allied to the Kashmir species, S. hians, Royle, figured at t. 6517 of this work, which differs mainly from S. brevilabra in having much larger corollas with longer lips, and in having leaves which are usually more regularly and less coarsely toothed. Plants of S. brevilabra, received from Messrs. Veitch under the name S. Souliei, have been in cultivation at Kew for the past twelve years. At Kew it has proved a hardy perennial, flowering about midsummer and ripening its seeds. The material for our plate has been supplied by Mr. H. J. Elwes, in whose garden at Colesborne, Cheltenham, it grows equally satisfactorily and has proved equally hardy.

This very distinct Coclogyne is a native of the Philip- pines, and was originally described in 1910, the locality being given as Mount Pulog, in the Province of Benguet, in the lower mossy forest, at about 7,000 feet above sea-level, where it was collected by Mr. E. D. Merrill in 1900. It had previously been collected by Mr. A. Loher in the same province, as is shown by specimens preserved at Kew. Some three years after it was described it appeared in cultivation, having been exhibited by Messrs. Sander and Sons at the Chelsea Show of the Royal Horticultural Society in May, 1913. It is allied to the rare Javan (. cinnamomea, Teijsm. et Binn., but has a pandurate lip, somewhat narrowed behind, instead of being broadly ovate, and the area between the entire keels is dark red-brown, with a band of the same colour on the side lobes. The rest of the flower is light green. The plant here figured was received from Messrs. Sander, - Juty-SePreMBER, 1920- St. Albans, in 1913, and our drawing was made when it flowered at Kew in June, 1916. Under cultivation, C. integerrima thrives well in a tropical house in a compost of fibrous peat and sphagnum. During its season of growth it requires a liberal supply of water, but when the growth has become fully matured all that is necessary is to supply moisture just sufficient to prevent the pseudobulbs from shrivelling.

Bran, The plate of the Barbery here figured was prepared from a plant raised from seed collected in Western Szechuan in November, 1908, at about 5000-6500 feet above sea-level, by Mr. E. H. Wilson. A share of this seed had been presented to Kew by Professor C. 8. Sargent, Arnold Arboretum, and was received under the ‘Wilson’? number 1284. The first of the resulting plants to flower at Kew did so in April, 1914. In his original elaboration of the barberies collected by Wilson, Mr. C. K. Schneider (Plant. Wils. vol. i. p. 360) identified the plant now figured with the species described by the late Mr. Franchet as B. levis. Further study, however, led Schneider to reconsider this deter- mination, and in a later section of the same work (vol. iii. p. 437) he made Wilson’s no. 1284 the type of a distinct species, B. atrocarpa, basing his differentiation JULY-SEPTEMBER, 1920. mainly on the “jet-black almost globose fruit’ of Wilson’s plant, the fruits of the original B. levis being ovate and blue-black. This particular feature we find, however, to be far from distinctive, for in B. atrocarpa the fruits before becoming jet-black are covered with a blue bloom, while, at least on our plant of B. atrocarpa at Kew, the fruits rarely approach a globose shape, their usual form being somewhat narrowly ovoid. Yet there is little room to doubt that Schneider is fully justified in regarding B. atrocarpa as specifically distinct from B. levis. The two species are certainly closely allied, and are both well marked among their nearest congeners by the immersed almost invisible secondary nerves of the leaves. Yet B. atrocarpa is easily distinguished from _B. levis by its angular grooved branchlets, by its thinner, longer and proportionately narrower leaf-blades, the serrations along the margin of which are more remote, and especially by the smaller number of flowers in a fascicle. We have not found more than eight flowers together in B. atrocarpa, and the number is rarely so great, whereas according to Franchet there are in B. levis sometimes as many as forty. B. atrocarpa is one of the most vigorous of evergreen barberies and one of the most formidably armed, its slender needle-like spines having a steel-like rigidity. It grows freely, and although it suffered to some extent in the hard weather of the early part of 1917, it soon recovered. Description.—Shrub of erect habit, 5-6 ft. high; branchlets stiff, grey, glabrous, sulcate, armed with very rigid, three-pronged, pale brown spines {-1} in. long; internodes 1-23 in. long. Leaves evergreen, in clusters of three to eight at each node, coriaceaus, glabrous, elliptic-lanceolate, 13-33 in. long, i-i in. wide, acute, slenderly cuneate at the base, subsessile or with a petiole up to 4 in. long; margins set with slender, forward-pointing teeth ;); in. long; dark rather glossy green above, paler beneath, very smooth; nerves scarcely perceptible.

Allium sikkimense belongs to the section Rhiziridiwm in which the bulb, instead of becoming globose or ovoid, remains cylindric, and often (as in the present instance) has its outer coat breaking up with age into parallel strands of tough fibres. Regel subdivides this section into those species which have a creeping ‘ rhizome” and those in which the so-called ‘‘rhizome”’ is perpen- dicular, but inadvertently places the present species, which he had not seen, in the former group; its bulbs, except the slightly curved ones at the outside of a clump, are cylindric and erect. A native of alpine Sikkim, A. sikkimense was discovered in August, 1848, by Sir J. D. Hooker at Lachen between 10,000 and 11,000 feet, and at Tungu at 14,000 feet, and was again collected in 1911 by Ribu and Rhomoo at Cholamoo, at an altitude of 16,000 feet. It flowered with Mr. H. J. Elwes at Colesborne, Cheltenham, in March, 1877, and again at the same place in June, 1919; in the latter case Juty-SEPpTEMBER, 1920. from material supplied by Mr. G. H. Cave. It is also established in the Rock Garden at Kew, where the plant here figured was raised from seed received in 1917 from the Royal Botanic Garden, Calcutta. At Kew it is quite hardy and ripens its seeds. Besides A. sikkimense, two other species of Allium with blue flowers have been in cultivation. One of these, A. kansuense, Regel (A. cyaneum, var. brachystemon, Regel) has been figured at plate 7,290 of this work and is a native of the Chinese province of Kansu, where it has been found during recent years at elevations of 9,000 to 10,000 feet by Mr. E. H. Wilson and Mr. R. Farrer; it has also been successiully grown by Mr. H. J. Elwes. It much resembles A. sikkimense, from which it differs in having all the filaments toothed at the base, a character which, although inconspicuous, may be of some significance in connection with pollination. The other species is A. cyaneum, Regel (Gartenflora, t. 1317, fig. 2), also from Kansu, which is readily distinguished by its filiform semiterete leaves and by its stamens being twice as long as the perianth and haying only their alternate filaments toothed at the base.

The genus Subia, belonging to the small but distinct order Sabiaceae, includes ‘some twenty-five to thirty species, mostly climbing shrubs, fairly widely distributed in Eastern Asia. Few of these have been introduced to European gardens, and hitherto no species of the genus has been figured in this work. The one here described, S. latifolia, was first discovered by Mr. A. E. Pratt in the neighbourhood of Ta-chien-lu. Twenty years later it was encountered again by Mr. Wilson in the same JuLy-SeEPpTEMBER, 1920, neighbourhood, growing in thickets at about 8,000 feet above sea-level. The plants now in cultivation were raised from seed collected by Wilson, though during the interval between its discovery and its introduction the species has been met with at least on two occasions; specimens from Szechuan were communicated by Mr. A. Henry in 1890, and others from Western Hupeh were gathered by Wilson in 1900. For the material for our figure we are indebted to Miss E. A. Willmott, in whose garden at Warley Place S. latifolia has been in culti- vation for the past nine years. Here it has thriven against a north wail, flowering and ripening its fruits every season. The original plant, which is now about ten feet high, was raised from the only seed which germinated out of a few collected by Wilson and received from the Arnold Arboretum. At Warley Place this plant has not been given any special protection, and has proved quite ardy.

Acacia spectabilis well deserves the name suggested for it by Cunningham on its first discovery in Wellington Valley, New South Wales, nearly a century ago, for in spite of the fact that as cultivated under greenhouse - conditions in this country it develops into a plant of somewhat straggling habit, it is when in full blossom an exceedingly beautiful object, the glaucous hue of the foliage greatly enhancing the effect produced by the yellow globose flower-heads it produces in such abun- dance. A native of the subtropical regions of Eastern Australia from about Lat. 26° 8. in Queensland to about 34° 8. in New South Wales, it was introduced to JULY-SEPTEMBER, 1920, European collections shortly after its first discovery, and has been in cultivation in England ever since. Doubt- less it has been reintroduced oftener than once; the last occasion on which this has occurred at Kew was in 1909 when seeds were received from the Sydney Botanic Garden. One of the plants raised then flowered for the first time in the Temperate House at Kew in February, 1914, when the drawing from which our plate has been _prepared was made. It has flowered freely in spring every year since then. As Mr. Hutchinson points out, _it is nearly related to two other Australian species of Acacia, A. polybotrya, Benth., and A. pruinosa, A. Cunn., both of which are to be met with in greenhouse collections. Description.—Shrub of considerable size; twigs eventually becoming purplish, at first covered with spreading pubescence, but soon becoming glabrous.

H. Wricur. Arisaema Fargesii was described by Mr. Buchet from specimens bearing male flowers only, collected at Hong- lan-sin, at an altitude of 6,000-7 ,000 feet, in the district of Tchen-keou-tin, in the province of Szechuan, but he refers to the same species a plant with female flowers, which he has seen growing in the collection of Mr. Maurice de Vilmorin, who had received it from Szechuan. This plant was larger in all its parts than the male plant upon which the original description was based, and agrees with the plant here figured, which was received at Kew in 1917 from Mr. de Vilmorin and flowered in May, 1919. The leaves of J. Fargesii resemble those of A, ringens, Schott, which differs in having a spathe with even more pronounced auricles but with a shorter apex. In colour, the spathe is like that of A. speciosum, Mart., but in this the spadix is produced into a long filiform appendix much longer than the spathe. The spathe in JuLy-Sepremperr, 1920 all the above mentioned species is inarched so as to form a hood, and the whole inflorescence is sheltered by the patently spreading leaflets, which are decurved in the upper part. At Kew this species thrives well, like the various Himalayan species of the same genus, under ordinary greenhouse treatment. Desoription.—Herb, with a depressed globose tuberous corm which produces @ solitary leaf along with a solitary flower spike. Cataphylls brown, narrowed upwards, obtuse or acute. Leaf 3-foliolate, glabrous; leaflets spreading, shortly petiolulate, the central somewhat rounded, cuspidate, 11 in. long; lateral rather shorter than the central, cuneate at the base on the inner, rounded on the outer side; petiole half as long again as the lamina, fleshy.

Fructus ruber, depresso-globosus, fere 1 cm, diametro.—J. Hutcurnson. The Rosaceous genus Stranvaesia includes only five or six species, closely related to each other and separable _ only by rather slight characters. The distribution of the various forms is interesting, for the genus extends in India from Kumaon to the Khasia Hills and Burma, and extends thence into central and western China, while a solitary species occurs at high altitudes on Mount Kina- balu in Borneo. So far no representative of the genus has been met with in the Malay Peninsula. The species here described as 8S. salicifolia is very nearly related to S. undulata, Decne, from China, figured at t. 8418 of this work. From S. undulata our plant differs in its narrower willow-like leaves, its quickly deciduous stipules and bracts, and especially in its fruits which are red in place of orange. From the horticultural standpoint at all events the two plants are abundantly distinct. Our plate has been prepared from an example which has JULY-SEPTEMBER, 1920, proved quite hardy at Kew, where it thrives well in loamy soil. It was received as a small plant from the Arnold Arboretum in 1910, and as cultivated alongside S. undulata has become a taller plant of much stronger growth, less compact in habit. It flowers freely and perfects its fruit in sufficient quantity to render it a singularly handsome autumn plant. It may be increased by seeds, Description.— Shrub or small tree with densely grey-tomentose young twigs which become dark-purple and adpressed pubescent in the following season. Leaves linear-lanceolate, narrowed to both ends, acuminate or long mucronate at the tip, quite entire, 14-34 in. long, 2-4 in. wide, thinly papery, pubescent along the midrib above, elsewhere glabrous; lateral nerves about 12 on each side the midrib which they leave at a wide angle, raised beneath, 2-furcate - towards the leaf-margin ; petiole over } in. long, densely adpressed-pubescent ; stipules very early deciduous.

CURTIS’S BOTANICAL MAGAZINE. In consequence of the increased and still increasing cost of producing Curtis's Botanical Magazine, the Publishers propose to terminate the fourth series with the present issue, Vol. 16 (1920), or Vol. 146 of the complete work. Before committing themselves further they desire to ascertain, in some way, whether the work fulfils a sufficiently useful botanical and horticultural purpose to justify its con- tinuance, and, if so, under what conditions it may be possible to do so.

A MAGAZINE CONTAINING HAND-COLOURED FIGURES WITH DESCRIPTIONS OF THE FLOWERING PLANTS INDIGENOUS TO SOUTH AFRICA. EDITED BY I. B. POLE EVANS, M.A., D.Sc, F.LS., Chief, Division of Botany and Plant Pathology, Department of Agriculture, Pretoria ; and Director of the Botanical Survey of the Union of South Africa. EXTRACTS FROM THE EDITOR’S PREFACE. Ir is proposed to issue this publication as an illustrated serial, much on the same lines as the well-known Curtis’s Botanical Magazine, and for imitating which no apology need be tendered. Should the publication be the means of stimulating further. interest in the study and cultivation of our indigenous plants amongst the rising generation, the desire and object of its promoters will be achieved. Living plants suitable for illustration, plants of economic value, or plants of general interest, will always be gladly received and welcomed by the Editor. The illustrations are from drawings by Miss K. A. Lansdell, while the descriptions have been prepared by Dr. E. Percy Phillips, Botanist in charge of the National Herbarium. _ The illustration on our cover represents a glimpse of the magnificent Union Buildings at Pretoria, under whose shadow this work is being prepared, and on whose site the plants here figured are grown. It has been the Editor’s privilege and good fortune to see a com- paratively bare kopje converted in the course of a few years into the site of a grand and stately building surrounded with many of the country’s most beautiful and interesting herbs and shrubs. For the contents of the first two numbers, see over. The work will be issued every three months, commencing on November Ist, 1920, each part containing ten coloured plates, price 15s., annual subscription 60s. (postage 2s.). LONDON: . L. REEVE & CO.

B. TurRRILL. Verbascum Blattaria, well known in gardens in this country, is also to be found, as a somewhat rare alien, in waste places from Lincolnshire southwards; in some of our southern counties it may perhaps be truly native. As a wild species it is widely spread in central and southern Europe, in northern Africa and in the Orient. Though it has long been in cultivation, the plant as grown in gardens seems always to have yellow corollas, though forms with the flower more or less white have occasionally been recorded in the wild state. The form OcropER—-DEcEMBER, 1920. here figured as var. grandiflora, in which the flowers are white and the corollas are much larger than in typical V. Blattaria, Linn., seems to be of doubtful origin. For the seeds from which the subject of our plate was raised Kew is indebted to the Director of the John Innes Horticultual Institution, Merton, and the original parent plant it is understood came from Lincolnshire, where it was found growing in a corn-field. At Kew it calls for no special treatment. The seeds were sown in 1918 and the plants flowered in 1919, those under green- house conditions in May, those in a border outside somewhat later, in both cases ripening seeds freely. Notwithstanding the striking appearance of this new variety, it differs from typical V. Blattaria mainly in the extreme luxuriance of all its parts. Description.—Herb, biennial ; stem 14-2 ft. high, with 2-3 branches towards the top, glabrous downwards, slightly and finely glandular high up.

The distinct and striking Rhododendron here figured is a native of Western China and appears to be confined to the province of Szechuan where it was first met with in 1885 by the Abbé David, near Moupine, at an elevation of about 9,000 feet above the sea. The plant from which the material for our plate was cut was obtained from the nursery of Messrs. J. Veitch and Sons at Coombe Wood in 1908. It had been raised there from seeds collected in Szechuan by Mr. E. H. Wilson. This plant is now four or five feet in height and forms a well- furnished, compact and handsome bush which usually flowers at Kew in March or April. The warmth of the OcroBER—DECEMBER, 1920, early weeks of 1920 however brought the blossoms of ft. strigillosum to perfection by the middle of February, when our drawing was prepared. This habit of early flowering renders the blossoms liable to injury by spring frost, and the young growths suffer from the same cause, It appears to succeed best in thin woodland, where it is shaded from the sun in the early and middle hours of the day. According to Mr. Millais the flowers vary in colour from rich red and crimson to white. The five black pouches at the base of the corolla are usually full of nectar. Even when out of flower &. strigillosum is readily distinguishable by its very bristly young shoots. Descrirtion.— Shrub, 4-5 ft., or at times a tree up to 20 ft. high ; twigs densely setose towards the tip, with long rigid blackish hairs. Leaves narrowly oblong-Janceolate, acutely acuminate, slightly narrowed and shortly cordate at the base, 3-6 in. long, 3-1} in. wide, firmly coriaceous: to nearly papery, reticulated above, beset underneath with crisped hairs; midrib sunk above and hispid towards the leaf-base, much raised beneath and tomentose ; lateral nerves about 12-18 along each side the midrib, from which they diverge at a wide angle, becoming obsolete towards the margin; petiole }—3 in. long, BY setose-hispid and tomentose. Inflorescence terminal, about 10-flowered ; bracts densely wooll y outside ; pedicels about 4 in. long, densely setose with black gland-tipped hairs. Calyx short, setose outside. Corolla red, with 5 black basal blotches inside; tube narrow campanulate, glabrous outside, 1} in. long, 1 in. wide at the throat; lobes 5, rounded, emarginate. Stamens 10, exserted; filaments pale purple, glabrous, about 1} in. long; anthers nearly black, 1 in. long. Ovary 5-celled, densely strigillose; style 1s pale purple, rather longer than the stamens, glabrous, tipped by the lobulate stigma, Capsule about 2 in. long, densely setose with rigid purple hairs.

The interesting /’ritillaria here figured is a charac- teristically Orient species with its headquarters in Thrace. It is reported to be plentiful near Constanti- nople and on the northern shores of the Bosphorus and the Sea of Marmora. Thence it extends southward into Bithynia and Anatolia, northward into Bulgaria and westward into Macedonia. It is usually found in woody places on hilly ground or among the foot-hills. The material for our plate was supplied by Mr. Hamilton Blanchard from his garden at Cotswold, Parkstone, the plant figured having been raised from a bulb sent from OcropeR—DECEMBER, 1920. Macedonia by Mr. Douglas Blanchard. To the latter we are indebted for the information that in Macedonia, as in Thrace, F’. pontica is generally distributed and prefers shade. Most of the bulbs sent by him to his brother came from a nullah running into Gumus Dere, near Kopriva, and the Sargest, from the slopes of Black Peak near Paprat. Here J. pontica flourishes under the shelter of bushes at about 3,000 feet above the sea. Mr. H. Blanchard’s experience with the plant extends over three seasons. The bulbs first received were all small and had been lifted very early; grown in pots in full sun the plants died without flowering. The second consignment, also lifted early, included some larger bulbs. The plants started growth too soon and were injured by spring frosts, some being cut to the ground. » Grown in sandy soil with partial shade and an eastern exposure, some of them flowered when six inches high. The final consignment, of mature bulbs, grown on the north side of a hich wall, produced plants which flowered when a foot high, formed capsules and matured seeds. In a soil suitable for other species of /’ritillaria* and if given sufficient shade, F” pontica is likely to prove hardy. The species belongs to the group Monocodon in which the bulbs are tunicated, the styles are tricuspidate and the nectaries are uniform. The colour of perianth appears to vary, especia'ly in cultivated plants, between dark green upwards tinged with purple and pale yellowish- green, but the absence of tesselation is constant. Description.—Herb, Stem erect up to 1} ft. high, usually 1-flowered, leafy above, naked in the lower half.

The Myrtaceous genus’ Melaleuca is a member of the tribe Leptospermeae, which includes many of the Australian plants that a century ago received much attention in English gardens and conservatories. _ The most familiar genera in the group are Lucalyptus, which includes the Australian Blue Gum, and whereof the species best known in our collections is the Tasmanian E. Gunnii, Hook. f., a mountain form of which is figured at t. 7808 of this work; Leptospermum itself, whereof L. scoparium, Forst., the Manukaof New Zealand, is most generally grown; and Callistemon, whereof the Australian species C. pinifolius, figured at t. 3989, is to be met with in English gardens. It is to the last named of these genera that Melaleuca, of which over a hundred species are known, is most nearly allied. Several of these have already been described in this Magazine, and will be found represented on tt. 1058, 1868, 1935, 2268, 3210, 4471, 6131, 7529, 7941. The species now described, M. Radula, which has not been figured hitherto, OcToRER—DECEMBER, 1920, possesses the added interest of having been unknown in European gardens even during the period when growers, were less unwilling than they are to-day to take the trouble called for in the cultivation of hard-wooded Australian shrubs. The material for our plate has been obtained from a plant raised from seed received from Australia in 1906 as that of Eucalyptus eugenioides, which flowered at Kew in October, 1915. This name being. obviously erroneous, the drawing then prepared was submitted to Mr. J. H. Maiden, Director of the Sydney Botanic Garden, to whom we are indebted for its identi- fication. A small virgate shrub, with rather narrow Spreading opposite leaves and large lilac purple flowers borne in axillary pairs, If, Radula flowers freely under greenhouse treatment in late autumn and is a welcome addition to conservatory collections. It is a native of Western Australia, where it was first collected in the Swan River district by Mr. James Drummond, and was first described from his specimens by Professor Lindley. Its natural range appears to be rather limited, though it 18 not uncommon within its special area, for it has since then been collected by Preiss near the Cunning River, by Oldfield at Champion Bay and on the Murchison River, and by more recent travellers in neighbouring districts. Its nearest ally in the genus is M. linearifolia, Smith, another species from Western Australia, from which J. ftadula is readily distinguished by the involute leaf-margins, and by the larger flowers which are never, asin M. linearifolia, arranged in a terminal panicle. Description.—Shrub of considerable size; glabrous. Leaves opposite, linear, acute, canaliculate, finely scabrid, margins involute or concave, il} in. long, 1-nerved, pellucid-dotted.

This handsome /Phlomis was first discovered in Kashmir by Victor Jacquemont during his travels in Ocroper-DecemBER, 1920. Northern India in 1828-32.. It has since been collected by several travellers in the same region, growing at elevations of from 3,000 to 8,000 ft., in the Kurrum Valley, Afghanistan, by Dr. Aitchison; and at Ziarat, Baluchistan, at 8,500 ft., by the late Mr. J. H. Lace. It does not appear to have been introduced into cultivation in this country till Mr. H. J. Elwes obtained seeds collected in Kashmir by Mr Radcliffe of the Forest Department, from which he raised some plants in his garden at Colesborne, Gloucestershire; from these he sent flowering material to Kew in September, 1916, and again in August, 1919. Attaining as it does a height of about six feet, with basal leaves up to a foot long and dense whorls of rather large rose-purple flowers, it forms a striking object in the herbaceous border. It is easily cultivated, Mr. Elwes informs us, in any soil and is quite hardy in the open. The genus Pélomis now comprises over eighty species, about twenty of which are or have been in cultivation. The well-known /. fruticosa, L., a native of South-eastern Europe, is occasionally found naturalised in England. In the Flora of British India it is suggested that P. oreophila, Kar. and Kir., from Alatau, is probably a small state of P. spectabilis. The two species are manifestly quite distinct. The plant now figured is assigned by Bentham to the first (Luphlomis) of the two sections into which the species of Phlomis are grouped. The flowers are, however, much ‘more correctly described in the definition of the sec- tion Phlomidopsis, which includes P. tuberosa and P. macrophylla, species obviously closely allied to P. spectabilis, Description.—Herb, perennial. Stem erect, sparingly branched, stout, cylindric, about 6 ft. high, 1-2 in. thick, sometimes ai fist more or less stellately hoary-tomentose, rarely sparingly hispid, at length glabrous and often glatfeous; internodes long, sometimes over'8 in. long. Leaves petioled, ovate-cordate, subacute or rounded at the tip, deep and widely cordate at the I or in the upper parts of the stem, cuneate or rounded, coarsely and irregularly toothed or at times faintly lobed, upper leaves often almost regularly dentate or serrate, green and sparsely pilose above, stellately hoary- tomentose beneath, main-nerves conspicuous; basal leaves 8-12 in. long, 6-11 in. wide; petiole hispid, 6-12 in. long; stem leaves gradually smaller upwards, the lowest 6 in. long, over 4 in. wide, with petiole from }-4 in. long, the uppermost reduced to bracts.

Rhododendron Sargentianum is a member of a group of some fifteen species of dwarf shrubby Rhododendrons with aromatic leaves, clustered capitulate inflorescences, tubular corollas that are usually villous within, short included stamens and very short capsules which are more or less invested by the hardened calyx. The species was discovered by Mr. E. H. Wilson in 1903 near Washan in Western Szechuan, when collecting on behalf of Messrs. J. Veitch and Sons, and was again met with by him, growing on exposed rocks near Moupine in the same province both in 1908 and in 1910. ‘The central species of the group to which it belongs is A&, OctoBeR-DeEcEMBER,. 1920, cephalanthum, Franch., also from south-western China. As is shown in our illustration, at fig. 8, the plant from which our figure was prepared has some of its filaments devoid of anthers; that this reduction may have been the result of cultivation is probable ; the presence of the tendency may nevertheless have some bearing on the taxonomic status of the group to which R. Sargentianum belongs. Being dwarf, compact and slow of growth, this species is admirably suited for cultivation in the Rock Garden, where it should be provided with a mixture of sandy loam and peat. It will probably thrive best in a nook shaded from the mid-day sun. Failing seed, it can be propagated by cuttings taken in July and placed in very sandy soil under a bell-glass in gentle heat. The plant now figured was presented to Kew by Mr. F. R. 8. Balfour of Dawyck, Peebleshire, in March, 1914. It flowers in May. Description.— Undershrub, reaching a height of 2 ft., much branched, the twigs erect or ascending, when young very short and loosely covered with soft scales, when older beset with persistent bud-scales, Leaves aromatic, wide elliptic, mucronate, sometimes slightly emarginate, base wide euneate passing into a stalk about ;; in. long which is lepidote on the back, 3-3 in. long, 3-} in. wide, coriaceous, at first loosely lepidote above, but soon glabrous and polished, below softly lepidote; midrib sunk above, raised and nearly glabrous beneath. Flowers loosely umbellately racemose, pale yellow; bud- scales somewhat persistent, wide obovate, long-ciliate, lepidote, about as long as the pedicels which are 1-1 in, long and covered with yellow scales. Calyx green, fairly large, lobes oblong, } in. long, rounded at the tip, long ciliate, loosely lepidote behind. Corolla hypocrateriform, lepidote outside except on the margins of the lobes; tube wide cylindric, over $ in. long, villous within ; lobes 5, spreading, nearly orbicular, 3-3 in. across.

This distinct and striking Mesembryanthemwn was presented to Kew in 1910 along with various other _ succulent plants by Mr. G. H. Simpson Hayward, Icomb Place, Stoke-on-the-Wold. It has thriven satisfactorily under the treatment given to other species of the genus in a warm greenhouse, where it flowered in November, 1918, when our figure was prepared. Beyond the fact that it is South African nothing is known of its history, for there is no record of the district in which it was collected, and no very near affinity can be found or claimed for this species, which is new alike to horti- culture and to science. In most respects M. dichroum accords with the members of the section Calamiformia, though it is at once distinguishable from all of these by having distinctly triquetrous in place of subterete leaves and in having petals with bright pink apices. It appears on the whole more satisfactory to include our plant provisionally among the Calamiformia, though as a somewhat anomalous member of the section, than to regard it as the type of a distinct section, though this OcroBER—DECEMBER, 1920. ; may eventually be found to be necessary. M. dichroum is a pleasing addition to the succulents in cultivation owing to the colouring of the petals. It is a dwarf plant with very glaucous linear-oblong leaves and with shortly pedicelled flowers; the petals, otherwise white, are strongly suffused with pink towards their tips. Description.—Herb, with short simple or sparingly branched suberect stems, 3-33 in. high.

The history of this handsome Odontoglossum is of unusual interest. The late Professor Reichenbach in 1876 described as 0. Humeanum a plant imported from Mexico which had then flowered in the collection of Mr. W. Burnley Hume. The characters were such as to lead Reichenbach to think it a natural hybrid; the parents suggested were QO. Rossii and O. ccrdatum, two Mexican ~ species described by Professor Lindley. Three years later another plant flowered with Messrs. J. Veitch and Sons. This Reichenbach described as O. aspersum, again, however, in the belief that it was a hybrid, but with the Ocroper-DeceMseEr, 1920. suggestion that while O. [ossii is one parent, the other might be O. maculatum, a Mexican species named by La Llave. Subsequent importations of 0. fossii have in- cluded a certain proportion of individuals that on flowering have suggested some admixture with O. maculatum, which is known to grow in the same district as O. Rossii. It seems clear now, however, that Mr. Hume’s plant was not the first instance of the flowering in this country of a natural hybrid between (0. Rossii and another species. — The plant figured as 0. cordatum by Paxton, which flowered with Mr. 8. Rucker at Wandsworth in 1847, is manifestly the same as the subject of our plate. This plant was afterwards transferred by Veitch to 0. maculatum, the fact that it is identical with O. aspersum being overlooked. The confusion of these two species themselves, for the plant figured as O. maculatum at t. 4878 is really O. cordatum, may have contributed to the uncertainty as to the parentage of this hybrid. That uncertainty has been increased by the circumstance that the whereabouts of Mr. Hume’s plant, if it still survives, is unknown, and by the fact that the material on which Reichenbach based his O. Humeanum has lain so long inaccessible in his herbarium. In any event it was essential, before it could be definitely decided whether either, and if so which of the suggestions made by Reichenbach be correct, that advantage be taken of the first suitable opportunity of effecting the necessary _ artificial cross-fertilisation. By a fortunate accident Mr. Rolfe was able to enlist the interest of Mr. F. H. Moore, of the Royal Infirmary, Liverpool, who in May, 1899, had O. Rossii and O. maculatum in flower together in his collection. The two species were crossed by Mr. Moore and some hybrid seedlings were raised, one of which has happily survived and has been the subject of careful observation. At six years of age this plant, which had not yet flowered, passed into the care of Mr. W. H. Young, then in charge of the collection at Clare Lawn. A year later, on the death of Sir F. Wigan, it came to Kew, where it has since been grown with other Odonto- glossums, planted in a smali basket suspended near the roof-glass of a cool orchid house. In 1918, when nine- teen years old, the plant flowered for the first time, producing the inflorescence of four blooms here figured: which agree exactly with those of the wild presumed natural hybrid collected in Mexico.
