Kerr in the Chiengmai district, Siam, tubers of which were forwarded by him to Professor H. H. Dixon for cultivation in the Botanic Garden of Trinity College, Dublin. The present species, one of the most striking, flowered there in March in the years 1910, 1911 and 1912 and ripened fruits in July, 1915; as is not unusual in the genus, the leaves appear after the flowers. For the fresh material at its various stages utilised in preparing our plate we are indebted to Professor Dixon. Mr. S. G. Wild, whose enthusiasm is so well known, and to whom the care of the tubers was intrusted, informsus that A. Kerriiis best grown in a compost consisting of two parts good loam with one part each of leafsoil, peat andsand. It requires ample pot-room, a genial atmosphere and a temperature Gaxwary, 1917, ranging from 65° to 70° F. during the growing season. Corms potted at the beginning of March flower in April and May, when adequate water should be supplied till about the end of September, an occasional application of liquid cow manure being beneficial. After September the pots may be stored in heated frames with a minimum temperature of about 45° F., and should be kept quite dry. The corms are readily increased by offsets, and if one is fortunate enough to fertilize the flowers, seeds may be obtained which, if sown as soon as ripe, produce new corms which should flower about their third season.

The Portugal White Broom, here figured, a native of northern and central Spain and Portugal, has had a somewhat chequered cultural history. Whether it be, as Lamarck and others have thought, the Genista alba aRy, 1917, ee te Fo re figured by Tabernaemontanus in 1588, seems open to doubt ; L’Escluse, whose Spanish notes were published in 1576, does not allude to the species, and Tabernaemon- tanus has not recorded the native habit of his plant. Tournefort, who met with this broom in Portugal in 1688, named it Cytisus lusitanicus foliis minimis argenteis parvo flore albo, and sent a specimen to Bobart, who iden- tified both it and some specimens of Retama monosperma, Boiss., with the Genista alba of Tabernaemontanus. The specimen given by Tournefort to Bobart is still in the Morison herbarium at Oxford, but that the plant had not been introduced to English gardens in 1699 when Bobart wrote, seems clear from the fact that there is no reference to it in the works of Ray. The earliest record of its cultivation in this country occurs in the third, or 1739, edition of Miller’s Dictionary, where, as well as in the three subsequent issues of that work, it is given as the Portugal Base-Tree-Trefoil ; in the second edition of the Hortus Kewensis, the younger Aiton, in 1812, refers to the circumstance that it was grown by Miller as recently as in 1752. Shortly thereafter the plant would seem to have been lost to English gardens; it is not included in the seventh edition of 1759, or in any later issue of Miller’s work; moreover, the elder Aiton, in the first edition of the Hortus Kewensis, in 1789, treated it as -a new Spartium, S. multiflorum, which he termed the Portugal White Broom, introduced to. this country by Mr. James Gordon about 1770. Since this second intro- duction the plant has persisted in our collections ; indeed, in 1812, a third introduction took place, this time of a form which is, however, but an unstable colour-variant, in which the flowers are flushed with pink. According to Loddiges, this form with incarnate blossoms was raised from seeds by Thomson at Mill-end; Loddiges, however, adds that “it may be increased by seeds which are perfected in abundance, but the produce are not all pink-flowered.” Indeed, as our illustration shows, sprays with white flowers and others with the petals tinged with pink may at times be present on the same plant. That the Portugal White Broom is, as Tournefort had decided, a Cytisus, is not open to doubt, and Willkomm has stated that Quer, who accepted this view, actually named it C. lusitanicus in conformity with Linnean principles. In the supplement to his Spanish flora Willkomm has accordingly adopted this obviously apposite name, and in this he has been followed by recent Spanish and Portuguese authors. Willkomm, however, has not cited the passage in which the name C. lusitanicus, Quer, occurs ; the name is not employed in the Flora Espanola published by Quer in 1762 and completed by Ortega in 1784. In 1789 Lamarck, adopting the view of Bobart, . treated this broom as a Genista, so that the name G. alba, Lamk, is the earliest verifiable one applied in conformity with modern usage. Unfortunately, long before Link, in 1822, retransferred the species to Cytisus, another C. albus, from south-eastern Europe, had in 1790 been duly described by Haquet. Meanwhile the elder Aiton, in 1789, had placed the Portugal White Broom in Spartium, as S. multiflorum; so that when Sweet, in 1826, corrected this error the species was transferred to Cytisus as C. multiflorus. In order to avoid the con- fusion created by the fact that the name C. albus had been used for two different brooms from south-eastern and south-western Europe respectively, recent writers, following Briquet, who has monographed the genus Cytisus with singular care, have feit constrained to employ for the Portugal White Broom the name C. multiflorus, Sweet, rather than the name C. albus, Link. In his monograph of the genus, however, Briquet has indicated that the plant described by Haquet, for which in 1803 Waldstein and Kitaibel proposed the name C. leucanthus, under which it was figured at t. 1438 of this work, is better treated as referable to C. supinus, Linn. So long, therefore, as the validity of the name C. lusitanicus, Quer, employed by Willkomm in 1893, remains doubtful, it is possible to follow Schneider in retaining for the Portugal White Broom the name C. albus under which, since the time of G. Don and Loudon, ‘it has been familiarly known in English gardens. Among the cultivated brooms C. albus is .dis- tinct and valuable in being the only really hardy species with white flowers. ° Others with flowers of a similar - shade are more or less tender; C. albus, even in very hard weather, remains unscathed, or at most only suffers an occasional cutting back of the young succulent growths. Planted in broad masses at Kew, where it has been in continuous cultivation since the time of the elder Aiton, it gives charming effects when in bloom in May. It does not need a rich soil, and as it ripens seed in abundance it is easily increased. The material for our plate was derived from a plant in the collection at Kew, with mixed white and pink-flushed flowers.

Wilson on the mountains of Western Hupeh at altitudes of 5,000 to 6,000 feet both to the north and south of Ichang. From seed collected by him in October, 1907, and received at Kew through the agency of the Arnold Arboretum the following spring, the plant now figured was raised. Since its introduction the winters have been mild and it has proved evergreen, but it is possible that, as with some other ordinarily evergreen Cotoneasters, its foliage may prove deciduous in our hard winters. It likes a sunny position and a loamy _ soil, and being very amenable to cultivation promises to _ develop into one of the finest members of the genus in gardens. It is easily increased by seed or by cuttings. — January, 1917. From the typical C. salicifolia, which we are not certain is at present in cultivation, the variety now figured differs in the leaves being broader ard duller green, and in their lower surface as well as the young branchlets being covered with a coarser, more woolly pubescence. Another variety, C. salicifolia var. floccosa, Rehd. et Wils., is cultivated at Kew, and is well distinguished by its narrower leaves and three-stoned fruits. The nearest ally of C. salicifolia- is C. Henryana, Rehd. et Wils., also from Western Hupeh ; this differs by its ovoid fruits and larger leaves pubescent on both surfaces. Description.— Shrub up to 10 ft. high of graceful habit, branches spreading. Branchlets slender, at first clothed densely with a pale brown wool, most of which falls away by autumn exposing the handsome, dark reddish-brown bark, Leaves stiff and coriaceous, persistent, oval to slightly obovate, acute, cuneate at the base, entire, 13-3 in. long by 3-14 in. wide; dark dull green, rugose and glabrescent above; at first wholly lanuginose beneath, ultimately greyish- white, with wool on the midrib and veins only; veins in nine to eleven pairs, deeply impressed above ; petiole »,-1 in. long, lanuginose.

Calif. 362, et Silva Calif. p. 235, tt. 7 & 73.—S. A. SKAN. Quercus densiflora was first discovered by David Douglas. His specimen in the Kew Herbarium is not precisely localised, but according to Hooker and Arnott it was in the Californian collection made by Douglas chiefly at Monterey and San Francisco. From Professor Sargent we learn that the species is distributed from the valley of the Umpqua River in Southern Oregon southward through coast ranges to the Santa Inez Mountains, east of Santa Barbara, California, and along the western slopes of the Sierra Nevada to Mariposa County. In the Sierra Nevada it ascends to an elevation of 4,000 feet above sea-level. It is exceedingly abundant in the humid Californian coast region north of San Francisco Bay, and attains its largest size in the Redwood forests oi Napa and Mendocino Counties. The Species is very variab‘e in habit and in its leaves, sometimes occurring as a low spreading shrub only 1 to 10 ft. high, with small entire leaves. This has been distinguished as var. echinoides, Sargent (= var. montana, Mayr = Q. echinoides, R. Br., Campst.). Pasania densiflora, forma lanceolata, Jepson, Silva Calif. 237, has lanceolate entire or nearly , entire leaves 24-33 in. long. The wood of this oak, though hard and strong, is brittle and is of little value except for fuel, but its bark is very rich in tannin and is used in enormous quantities for tanning leather. Professor Jepson states that in 1907 the annual tan harvest was about 25,000 cords, and to obtain this amount 100,000 trees were sacrificed every year, most of them being left in the forest to decay or to be consumed in the first forest fire. Best known as the Tan Oak, it is sometimes called Burr Oak and often. Chestnut Oak, and locally Squaw Oak and Sovereign Oak. The species is of great interest as being the solitary representative in the New World of the section Pasania, often regarded as a genus distinct from Quercus, which comprises about 100 species nearly all of which are confined to South-eastern Asia. Its dense erect or sub- erect catkins, resembling those of Castanea, small anthers with pollen-grains much smaller than in Quercus proper, and woody thick pericarp are salient characters by which it ae easily be distinguished from all other American Oaks, Notwithstanding the unusual interest of this tree it is one of the rarest of cultivated oaks. Two trees at Kew, if we except some young plants recently raised, appear to be the sole representatives of Q. densiflora in this country. From the larger of these material for our figure was obtained. This tree was raised from a packet of acorns received from Professor Sargent in 1874, and is growing in the Oak Collection near the southern end of the Rhododendron Dell. In some respects Q. densiflora is the most attractive of all the hardy evergreen oaks. The young leaves are covered on the lower surface with a thick tomentum which is at first milk-white, becoming tawny with age. The stout parallel ribs are also very distinctive. The tree is very leafy, almost luxuriant in aspect, yet it is slow-growing, and the larger of the two specimens at Kew, now over forty years old, is only 274 feet high, its trunk at 3 feet from the ground being > 21 feet in girth. In July, 1897, this tree was 14 feet high and 7 inches in girth. Like all oaks, Q. densiflora likes a good loamy soil. It transplants extremely badly—a fact which may help to account for its rarity. It is safest to grow it in pots until it is large enough to plant out in a permanent place, which should be done as soon as possible. Care must also be taken that its roots do not become pot-bound. Its leaves persist for three or four years, and its fruits ripen at the end of the second year. These, however, cannot be relied on in this country for propagation. -It must be raised in the first instance from imported seeds. __ Descriprion.— Tree, often 50-80 {t., sometimes 100 ft. high, trunk usually 34 ft., occasionally 5 ft. thick; branches ascending or spreading ; twigs at first tawny tomentose, at length dark brown and glaucescent. Leaves evergreen, oblong, oblong-obovate or broadly lanceolate, acute, subacute or shortly acuminate, sometimes rounded, base more or less rounded, sometimes cuneate, rarely shallowly cordate, margin serrate or serrulate, sometimes repand or quite entire, 2-5 in. long, 3-23 in. wide, coriaceous, slightly rugose, the edges thickened and revolute, at first densely clothed with tawny stellate hairs, when mature glabrous and shining or sparingly stellate-tomentose above, at length nearly glabrous on both surfaces, beneath occasionally somewhat glaucescent, the mid-rib and main nerves prominent beneath; potiole stout, tomentose, 2-3 in. long; stipules oblong-obovate or linear-lanceolate, brown, scarious, pilose. Catkins leans in the axils of leaves of the current season, erect or ascending, dense-ftowered, tomentose, either wholly male or with the upper- most bearing a few basal female flowers, 2-4 in. long. Male flowers clustered in groups of 3, in the axils of ovate bracts. Perianth tomentose, 5-6-lobed, the lobes ovate-elliptic or nearly triangular, obtuse or somewhat acute. Stamens often 10-12; filaments very slender, much exceeding the perianth; anthers subglobose, very small. Rudimentary ovary pilose. Female flowers solitary, in the axils of acute bracts. Perianth 6-lobed, the lobes rounded. Stamens 6, their anthers sterile. Styles 3, rarely more, elongated, terete, slightly recurved, hirsute at the base. Fruits solitary, or 2-8 together.

The fine Rhododendron here figured is a native of western Hupeh, where, according to Mr. E. H. Wilson, to whose efforts its introduction is due, it is the common species of wocds up to an elevation of 8,000 feet. It is s readily recognised, in the group with glabrous leaves to which it belongs, by its large white flowers with glabrous Feprvary, 1917, nee filaments and rather densely glandular style. In beauty and fragrance it is equal to any of its immediate allies, and is further readily distinguished from these by the valuable cultural character of being the latest in its group to flower. As compared with the related /’. Mor- tunei, Lindl., figured at t. 5596 cf this work, which flowers in May, &. discolor dces not come into blossom until the middle of June, a season when few Rhododen- drons of either wild or garden origin are to be found in bloom. Our plant also possesses another character valuable in this country, in being late of starting into growth; with the exception of &. auriculatum, Hemsl., from Central China, it is probably the latest. This renders it free from the danger of late frosts; so far as ordinary winter cold is concerned it is also perfectly hardy. The plant which provided the material for our plate was raised at Kew from seed collected by Wilson in autumn in 1908, received from the Arnold Arboretum early in 1909. — Description.— Shrub of robust habit, 6-8 feet high ; terminal twigs cylindric, about % in. thick near the tips, glabrous, somewhat polished.

Purpus in the Sierra de Mixteca, Oaxaca, Mexico. He saw it in only one locality, and that was on the slopes of the Cerro de la Yerba, growing on limestone rocks and on the walls of old ruins. As seen in nature, with its growths hanging over the rocks and bearing numerous showy flowers, it presented a striking object. Seeds were sent to the Darmstadt Botanic Garden, from which some were received at Kew in 1912, and plants raised from these flowered in the Temperate House for the first ca _ time in July, 1915, supplying material for the present illustration. In the original description the peduncles _ are said to be only about two inches long, and the photographs in Méllers Deutsche Girtner-Zeitung of Fesrvary, 1917. plants which flowered .in the nursery of Mr. Herb of Naples represent peduncles about as long as the petioles, though in the text the flowers are described as being long-stalked. The peduncles in the Kew plants were three to fourincheslong. This is probab!y due to indoor cultivation. Mr. A. Purpus recommends the plant for sunny, dry places. Protected from wet, the tuberous rootstocks survived the winter out of doors at Darmstadt. The species is described a3 non-climbing. At Kew the stems have reached a length of about 3 ft. and do not show the tendency to climb by means of the petioles met with in most Maurandias; J/. Purpusii differs markedly in this respect from its close ally, IM. erubescens. Only one species, MZ. erecta, Hemsl., so far as is known, has a distinctly erect self-supporting stem. The genus Mau- randia comprises eight species (or seven if I. geniculata, Robinson & Fernald, be referred to Jf. erecta, which it resembles very closely) all of which are natives of Mexico, one, M. Wislizenii, Engelm., extending to New Mexico. M. erubescens and M. semperflorens, Ort., have become naturalised in some of the West Indian Islands and in some parts of Tropical America. These two species and M. scandens, A. Gr., are figured in this Magazine at tt. 460, 3037, 3038 and 3650. _ Descriprion.—Herb, perennial, shortly glandular-pubescent; base of stem and roots thick and fleshy. Stem slender, ascending or prostrate, hardly scandent, 3-4 ft. long. Leaves alternate, petioled, wide triangular-ovate, acute, base deep-cordate, irregularly toothed or crenate, at times nearly entire, 13-1} in. long, 13-2 in. wide at the base; petiole 1}-1% in. long. Flowers showy, long-stalked, solitary in the upper axils; peduncles ascending, slender, in. long, usually longer than the leaves. Calyx herbaceous, 5-partite almost to the base; lobes oblong-ovate, rather rounded and apiculate, base cordate, about 2 in. long, } in. wide. Corolla bright rose-purple, 14-1} in. long, almost glabrous externally ; tube narrow-funnel-shaped, slightly swollen at the base in front, glandular-pubescent within, especially at the base; limb patent, 2-lipped, almost equally 5-lobed, about 1 in. across ; lobes suborbicular, about } in. wide.

The genus Senecio is represented in New Zealand by some thirty species which vary in habit from small weeds resembling the Groundsel of our gardens to much- branched shrubs with leathery leaves like S. Monroi, the subject of our illustration. This species, which is con- fined in a wild state to the South Island of New Zealand, where it flowers from December to January, along with a few others bears considerable resemblance in habit and appearance to some of the species of Olearia, Moench, so characteristic of New Zealand, but is readily distinguished by the fewer involucral bracts as well as by the different style-arms, which in Olearia exhibit the Feprvary, 1917. characters that mark the tribe Asteroideac. S. Monroi was first sent to Kew in 1905 by Mr. G. Matthews, Dunedin ; at Kew it is grown in the cool greenhouse and flowers in autumn. The material for our figure came from the garden at Ludgvan Rectory. Long Rock, Cornwall, where, the Rev. Mr. Boscawen informs us, it was raised by him from seed sent to him from New Zealand in 1907. At Ludgvan the plant grows well in any ordinary garden soil and flowers freely; some of Mr. Boscawen’s examples are now compact bushes three feet in height and about four feet through. Description.— Shrub, much branched, 6-7 ft. high; twigs densely leafy, shortly white woolly. Leaves petioled, oblong or oblong-lanceolate, obtuse, gradually narrowed to the base, $-1 in. long, about 2 in. wide, margin thickened and distinctly undulate-crenate, thickly leathery, above finely reticulately veined and slightly viscid, beneath shortly white woolly, midrib raised but venation otherwise not visible ; petiole 1-2 in. long, with a thickened partly stem-clasping base, white woolly.

DROWN, The Urticaceous genus Pilea includes over two hundred species dispersed throughout the tropics of both hemi- spheres. Of these the best known is the tiny P. muscosa, Lindl., the ‘ gunpowder plant,’ so-called from the cloud of pollen discharged from the anthers when the plant is shaken—a common South American species which has become introduced into India, and even into Australia where alone no native Pilea occurs. Very few species are in cultivation, the only ones to be met with in collections so far being P. grandis, Wedd., a native of Jamaica, with large green, dentate leaves in shape recalling those of a Coleus, and P. Spruceana, Wedd., a native of Peru, with ovate dark bronze-green foliage. To these have now to be added the attractive foliage _ Fesruary, 1917. plant which is here figured. This species, P. Forgeti, was discovered in Venezuela by Mr. L. Forget in 1914, when collecting on behalf of Messrs. F. Sander and Sons, St. Albans, by whom it has been introduced to culti- vation. The dwarf habit with bright bronze foliage striped with green give it a pleasing appearance when out of flower. The sexes are distinct, and in the case of the female plant, in which the flowers are inconspicuous and hidden away in small dense clusters in the axils of the leaves, the general facies of the plant remains unchanged. In the case of the male, however, flowering adds to the charm of the plant owing to the develop- ment of pairs of dense clusters of small white flowers raised on long pink stalks well above the foliage. Like the few species already in cultivation, P. Forgeti is easily grown in a tropical house, and like them sets seeds in abundance.

Cliftoni, differs markedly from the previously known members of its genus in having a deeply saccate base to the lip, which Marcu, 1917, has a narrow strongly recurved frontal lobe, and in the shorter column which is constricted below the apex and much swollen above the base. The locality of the original plant has not been stated, but the species is known to occur in the district of Antioquia in Colombia. The material for our figure has been obtained from a plant imported by Messrs. Sander. Like other members of the genus, A. Cliftoni thrives in the intermediate house. It is most suitably grown in a compost of turfy loam and peat, with a small proportion of chopped sphagnum added to the mixture. During the growing season the plant requires a liberal supply of moisture at the roots and should be kept shaded from bright sunshine. When at rest only sufficient water should be given to keep the pseudobulbs plump; the plant may then be given a brighter and more airy situation, thus ensuring the ripening required to induce satisfactory flowering. Description. — Herb, terrestrial, 1-13 ft. high ; pseudobulbs clustered, ovoid- oblong, 4-6 in. long, 13-23 in. wide, 2-8-foliate.

The Barbery here described is one of a group of Chinese forms with dull foliage, among which Berberis Wilsonae, Hemsl., figured at t. 8414 of this work may be regarded as the type, but which includes also the very closely allied B. subcaulialata, C. K. Schneider. The species now figured was originally described by Dr. Schneider as B. Stapfiana from a plant in the Barbery collection at Kew, which had been presented by Mr. M. L. de Vilmorin in 1910 under the name B. subcaulialata, from which it _ differs in the characters pointed out by Mr. Hutchinson. The plant from which our illustration has been prepared: 1s not, however, the original type of B. Stapfiana, but Marca, 1917, . ~~ one raised from seed collected by Mr. E. H. Wilson sent to Kew in 1909 from the Arnold Arboretum. The seed in both instances came from Western China; the precise locality is not known in either case. The long arching shoots, which are produced annually, impart to our plant a free and graceful habit; its being practically an evergreen affords an additional merit; it attains its greatest beauty in the fruiting condition, in October and November, later in the year perhaps than is the case with any other Barbery. It likes a good loamy soil and a sunny position; the abundant seeds render its propa- gation easy. How far the differences between the three plants with dull-grey foliage above alluded to may be Specific seems open to doubt. In a recent communica- tion Dr. Schneider has suggested that possibly both of the forms described by him as distinct may be varieties of the species described by Mr. Hemsley. While there is much to favour this view, the fact remains that B. Wilsonae, Hemsl., is readily distinguished by its downy twigs from the two plants described by Dr. Schneider, in both of which the twigs are devoid of hairs; of these two, B. Stapjfiana differs further from B. Wilsonae as regards the form of its ripe fruits. Description.—Shrub, about 5 ft. high; stem long, branches arching, ridged; twigs glabrous, tawny-purplish, finely pustulate or smooth; spines 3-partite from the base, slender, very acute, tawny-straw-coloured, distinctly channelled beneath, 2-3 in. long, the lateral diverging from the main spine at a right angle.

The Clematis which forms the subject of our illustra- tion is a native of western Szechuan, where it is found in woodlands, but where it appears to occur somewhat sparingly. At one time thought to be a distinct species, C. Souliei, Franch., it has recently been regarded as only a form of C. Fargesii, Franch., also a native of south- western China, and indeed to differ but slightly from that plant, as originally described, in having filaments considerably longer than the anthers, and perhaps also in having the leaflets more rounded or more widely cuneate at the base. C. Furgesii is a member of the Vitalba group of species ; within that group it is readily < Maeee, 17, . distinguished by its one- or two-flowered axillary ‘ peduncles and by its large and conspicuous flowers. The plant from which the material for our figure was obtained was raised at Kew from seeds received from the Arnold Arboretum in 1912. It flowered for the first time in 1915; the specimen figured was gathered in 1916. Plants continue in flower from June to September; they grow vigorously in a loamy soil, give every evidence of being hardy in our climate and develop sufficient seeds to make propagation easy. As a climbing shrub for gardens this Clematis will be valued for the pure white- ness and delicate satiny texture of its flowers, Description.—Shrub, climbing; twigs sulcate, shortly tomentose when young, ultimately sparingly pubescent, reddish-purple.

The very distinct and somewhat peculiar Mesembryan- themum here figured was first met with in J anuary, 1907, at Moutons Vley, near Piquetberg, Cape Colony, at an elevation of about 2,000 feet above sea-level. It has since been introduced to European collections by its ‘discoverer, Mr. N. S. Pillans. The species has not yet flowered at Kew, and the material from which our plate has been prepared was obtained from a plant presented by Mr. Pillans to the Cambridge Botanic Garden in 1913 which flowered there for the first time in J une, 1914, Mr. R. I. Lynch, to whom we are indebted for this material, informs us that the conditions suitable for other members of the genus meet the requirements of M. Pil- lansii, The nearest ally of M. Pillansii is M. lacerum, Haw., which it much resembles in foliage, but the very remarkable spathulate petals at once distinguish our Marog, 1917. et 2 4 8 one plant not only from MM. lacerum, but from every other known member of the genus.

The Strawberry-Raspberry is a fruit which, during recent years, has attracted attention for its handsome appearance, though, in spite of its being sweet and palatable, it is somewhat disappointing as regards flavour. It is a Rubus with a herbaceous stem which in summer attains a height of eight inches, but in winter dies down to the ground. At Kew it is quite hardy, thriving well in loamy soil and in full sunshine. It may be propagated by seeds or by division of the old plants in early spring. The history of this Rubus is rather a confused one. There is a figure of the plant in the -Phonzo Zoufou which is characteristic and unmistakable, Jn 1872 Mr. Maximowicz referred to the presence in Aprit, 1917. Japan of two forms of R. rosaefolius, Smith; one of these, termed alpina, has 1-2 terminal flowers on its dwarf young stems, with fruits an inch long; it was suggested that this form might be the doubtful RZ. chinensis, Ser., described in 1825. That thisis not the case is shown by the comparison of our material with a fragment and with a natural-size photograph of the original specimen of 2. chinensis kindly presented to the Kew collection by Mr. C. de Candolle ; Ft. chinensis is a shrub, nearly allied to £. rosaefolius, which was collected in China by Sir G. L. Staunton, the type specimen of which was presented to Mr. A. P. de Candolle by Mr. A. B. Lambert. Some time later than 1872 the Strawberry-Raspberry was introduced into American gardens and grown as R. sorbi- folius. It subsequently reached Europe under this name, as a plant of somewhat doubtful origin, though probably Japanese. In 1899 Dr. Focke proved that the plant is not ft. sorbifolius, Maxim., and described it as a new species, ft, illecebrosus, allied to the western Chinese RP. xvantho- carpus, Bur. & Franch., without, however, indicating its identity with Maximowicz’s alpine form of R. rosae- folius and with the Phonzo Zoufou plant. Still later Dr. J. H. Wilson, overlooking Focke’s account, referred to our plant as R. rosaefolius, “better known in gardens as Lf. sorbifolius, the so-called Strawberry-Raspberry.”’ Modern Japanese authors, apparently equally unaware of the existence of the name &. illecebrosus, consistently treat our plant as a dwarf mountain form of R. rosae folius, notwithstanding the evidence to the contrary which its herbaceous habit affords. Description.—Herb 6-10 in. high ; root perennial, creeping and giving off offsets ; stem erect, annual, angled, glabrous, prickly.

Hectori, the subject of our plate. It is readily distinguished from its New Zealand congeners by its foliage, the basal portion or petiole of the lower leaves being pinnately lobulate, while the remainder of the leaf-blade is repand- dentate. This species is apparently confined to the South Island where it occurs in the Nelson and West- land districts, at elevations of from 250 to 3,£00 feet above sea-level. It flowers there from December to February, and in favoured localities the flower-heads are at times two and a half inches across. For the intro- Aram, 1917. duction of this fine plant horticulture is indebted to Captain A. A. Dorrien Smith, Kingshill, Berkhamsted, by whom it was brought to England in 1910, when an example was presented by him to Kew. The Kew plant has thriven well in a cool greenhouse, but has not yet flowered, and for the material from which our illustration has been prepared we are indebted to its introducer, with whom one of his own examples blossomed for the first time in July, 1913. As a conservatory plant S. Hectori should prove a welcome acquisition; at Kew it is unfortunately too tender for cultivation out of doors. Description.—Shrub, erect, branched, reaching a height of 12-14 ft.; branches stout, spreading, pubescent, leafy towards their extremities. Leaves: lower obovate-elliptic, somewhat acute towards the base, pinnately lobulate where they pass into the petiole, the margin elsewhere repand-toothed, the teeth somewhat sharply mucronate, é-+ in. apart, 6-10 in. long, 3-5 in. wide, finely but sparingly pustulate above, sparsely woolly beneath ; upper sessile, elliptic- lanceolate or lanceolate, almost glabrous and nearly entire.

Forrest in May and June, 1912, at elevations of from 5,000-7,000 feet in the Shweli Valley and on the hills to the south of Tengueh in Yunnan, is one of a group of species the hitherto known members of which are C. brevipes, Clarke, a native of the Khasia Hills, and C. speciosa, Kurz, which was discovered in south-western Yunnan at Poneline by the late Dr. J. Anderson. Yet another, but as yet an undescribed species belonging to. the same group has been found, also in Yunnan, at 4,500 feet elevation, near Szemao, by Dr. A. Henry. The _ Szemao plant has leaves that are almost exactly like «Ape, 1017, those of the Tengueh species which its discoverer and Mr. W. W. Smith have named (. 7, railliana, but the calyx-teeth are narrowly linear above the base and the blossoms are aggregated in cymes of about four flowers, borne on peduncles as short as those of the Khasian C. brevipes ; the flowers, however, develop very unequally and there is probably, as in (. Trailliana, only one open at a given time. Examples of this Szemao plant from rather higher elevations have, however, peduncles with solitary flowers, and it is not impossible that it may eventually prove to be a form of C. Trailliana. The plant from which our figure was prepared was obtained for the Kew collection in 1915 from Messrs. R. Wallace and Company, Colchester, by whom it had been raised from seed collected by Mr. Forrest for Mr. J.C. Williams, Caerhays Castle, Cornwall. It flowered in June in a greenhouse, and is evidently too tender to thrive out of doors in Britain. I¢ survived at Kew after flowering, but failed to mature seeds, : : Description.—Herb, perennial; stem short, creeping, densely rusty-hirsute.

Monogr. Saxifrag. p. 189.—M. L. Green. The Saxifrage which forms the subject of our illus- tration was first described, as a variety of S. punctata, Linn., in 1872 by Engler. The plant on which the original account was based had been collected by Wilford on the coast of Manchuria in 1857. The Linnean species with which Engler thus associated Wilford’s plant has a wide range in northern Asia, arctic America and the Rocky Mountains; so far, however, as is yet known, Wilford’s Saxifrage appears to be confined to Manchuria and northern Corea, where according to Komarov, who in 1904 first indicated the desirability of regarding it as a distinct species, it is to be found in shady damp places on stream-banks. From S. punctata S. manshuriensis differs in being a more robust plant with larger and thicker leaves, in having the petioles and scapes hirsute, and in having the inflorescence globose and contracted. The plant from Aprit, 1917, : which our figure has been prepared was raised at Kew from seed obtained from Messrs. Regel and Kesselring, Petrograd, in 1913. The majority of the plants thus raised flowered for the first time in 1915. In the Rock Garden at Kew S. manshuriensis is in flower from July to August. It has proved a hardy perennial, easy to cultivate, which flourishes well in moist shady spots. Description.—Herb, fleshy, scapigerous, with a short, stout rootstock. Leaves several radical, long-petioled; lamina rounded-reniform, 2-23 in. long, 22-33 in. across, coarsely crenate, the teeth apiculate, dark green and glabrous above, paler and sparingly finely pilose beneath, the margin very shortly ciliolate ; petiole 4-53 in. long, hirsute, reddish. Scape solitary, about 14 in. long, rather densely‘hirsute with gland-tipped hairs. “Panicle terminal, much congested, subglobose, about 14 in. across; bracts linear, the lowest about in. long, acute, reddish; pedicels densely glandular-pilose.

The genus Corylopsis has its chief centre in China, | whence it extends to the Eastern Himalaya on the one hand, to Japan on the other. The various species are charming in gardens for their early blossoming, their soft yellow flowers and their gracious perfume. The species which forms the subject of our illustration, C. Wilimottiae, has all these qualities ; it grows freely, and so far it has, since it reached this country, given no sign of being at all tender. Like other members of the genus, however, it is liable to suffer, when in flower, from late spring frosts which mar its beauty though they do not affect its growth. The introduction of C. Willmottiae horticulture owes to Mr. E. H. Wilson, by whom it was first dis- i: Arar, 1017. — s : covered in 1908, south-west of Tachien-lu in Western Szechuan, growing at altitudes of 6,000 to 7,5€0 feet. Two years later Wilson collected seeds again in the same locality, and from these seeds of 1910 most of the plants now in cultivation were raised. The plant which has provided the material for our plant was purchased for Kew from Messrs. J. Veitch and Sons in 1913, and flowered there in April, 1914. The species had, however, blossomed two years previously in the garden of Miss E. A. Willmott at Warley Place, and was exhibited by her ata meeting of the Royal Horticultural Society in March, 1912, as C. multiflora, Hance, another Chinese species. It ripened seeds at Kew in 1916. C. Willmottiae is more closely allied to C. Veitchiana, Bean, figured at t. 8349 of this work, than it is to @ multiflora, but from our plant C. Veitchiana may be readily distinguished by its pilose calyx and fruits, by its longer nectaries and by its exserted red anthers. Description.— Shrub, 6-12 ft. high; young branches slender, glabrous, minutely lenticellate the second year; winter-buds pale shining green, stalked, Leaves deciduous, obovate, ovate or oval, 1-8} in. long, 3-23 in. wide, rounded or cordate at the base, acute or short acuminate, shallowly and widely denticu- late; deep green and glabrous above, glaucous and at first silkily pilose beneath, ultimately nearly or quite glabrous ; veins seven to ten on each side the midrib ; petiole 3-4 in. long, glabrous, or at first slightly pilose ; stipules ovate-lanceo. late, 3-1 in. long, purplish, glabrous outside, silky within, soon falling.

The distinct and handsome Vanda here figured is a native of the Philippines. It was collected in central Luzon, in the Montalban district, by Mr. A. Loher in May, 1905, and dried specimens from this locality, accompanied by a photograph and drawings, were presented by him to the herbarium at Kew in 1906 under the name V. /uzonica. That living plants had already been introduced to culti- vation in Europe is shown by a reference to the fact that the species, under this name, was then alive in the orchid collection at Erlangen. The plant from which our figure has been prepared was purchased for the orchid collection at Kewin 1911 from Mr. ©. F. Karthaus, Potsdam. But although the name V. luzonica was already in use among orchid growers, no description of the species was pub- lished until 1915, when a plant flowered in the collection of Mr. H. Dixon, Sydney, New South Wales. A little later in the same year it was exhibited in flower at the Panama Exhibition. In November, 1915, it also flowered in the collection of Messrs. Sander and Sons, St. Albans, May, 1917. and in December, 1915, the Kew plant, too, flowered for the first time in a tropical house where it had been grown and had thriven well under the conditions suitable for V. tricolor, Lindl., a species from Java, figured at t. 4432 of this work, which is its nearest ally in the genus. Though so closely related the two species differ very markedly in coloration, the sepals and petals of V. luzonica being white, not yellow, with a tinge or, at times, a defined spot of purple towards the apex, but with no trace of the brown blotches which characterise the sepals and petals of V. tricolor. Description.—Herb, epiphytic, 10-12 in. high; stem stout, erect, clothed with leafy sheaths, Leaves recurved, oblong, shortly 2-lobed, coriaceous, con- duplicate at the base, 6-14 in. long, 1-1} in. wide.

This interesting and pretty plant, the Bog or Swamp Wintergreen of North America, was originally described from material collected by Dr. Knieskern at Oriskany, Oneida County, New York, where it was found in Sphagnum swamps. It is now known to be distributed from Nova Scotia to New York, South Dakota, Colorado, May, 1917, Oregon, and from Washington to Alaska, in bogs, meadows and copses. The material figured came in June, 1916, from Mr. F. R. 8. Balfour, of Dawyck, Peeblesshire, where the plant was grown from roots collected by him in the Olympic Mountains, Washington. Pyrola uliginosa belongs to the section Thelaia, characterised by having the petals smooth, not tuberculate, at the base, ascend- ing stamens, and a declinate style dilated near the apex into a ring or collar, and contracted above into a stigma of five erect lobules. The connivent stamens are directed towards the upper petals, while the style curves sharply away from them towards the lowermost petal, which forms a kind of lip. To this section belongs the well-known P. rotundifolia, Linn., distinguished from P. uliginosa by its more coriaceous shining leaves, larger white flowers and much longer calyx-lobes. The variety incarnata, DC., of P. rotundifolia (P. incarnata, Fisch.) of Eastern Asia has rose-coloured or reddish flowers, and some botanists have identified it with P. wliginosa, but it differs in its more coriaceous shining leaves and longer calyx-lobes. The North American P, asarifolia, Michx., is distinguished by its suborbicular-reniform Jeaves, which are usually more or less cordate at the base. The characters distinguishing P. wliginosa from P. bracteata, Hook., are mentioned in the remarks on that species, a figure of which is also given on t. 8710. Descriprion.— Herb, perennial, with a long creeping rootstock; stem very short. Leaves nearly orbicular or ovate-elliptic, apex rounded rarely somewhat acute, base slightly cuneate and at times unequal, finely crenulate, up to 8 in. long, 23 in. wide, thin, quite glabrous, dark green but not polished above, paler and sometimes reddish beneath; petiole up to 4 in. long, sharply 8-angled.

The area it occupies is more restricted than that occupied by P. uliginosa; it extends from British Columbia to Idaho and California, in open coniferous woods. The material for our illustration was May, 1917, communicated by Mr. F. R. 8S. Balfour, of Dawyck, who lifted the roots in the valley of the Olympic Mountains whence came the plant of P. uliginosa figured along with P. bracteata. At Dawyck P. bracteata has been grown along with P. uliginosa in a Vaccinium bed in a soil of peat and leaf mould with sand admixed. The subsoil is gravel; the bed is at the base of a steep bank covered with high trees, and is in close proximity to a stream. The site is thus well shaded and the atmosphere con-. stantly moist. There are several points which render the discrimination of P. bracteata from P. uliginosa far from difficult, notwithstanding the resemblance they bear to each other. In P. bracteata the leaves are usually acute and the veins end in distinct, though minute marginal teeth. The bracts in P. bracteata are larger, the calyx teeth are longer and of a different shape; the petals are longer and narrower, and when fully expanded give the flower a 2-lipped appearance ; moreover, the anthers are yellow, not purple or rose as in P. wliginosa. Gray states that, at times, the leaves of P. bracteata are variegated with whitish bands. The two vernacular names are used, according to Parsons and Buck, in California, where a preparation possessing astringent properties is made from the plant and is used medicinally as a tonic and diuretic. : — Dxscription.—Herb, perennial, with a long creeping rootstock; stem up to 2 in. in theight.

The Manchurian genus Plagiospermum, Oliv., is closely allied to the Himalayan genus Prinsepia, Royle; the two have by some been regarded as sections of one genus. They are, however, very distinct; in Prinsepia the buds May, 1917, are perulate, the leaves exstipulate, the stamens in- definite with discrete anther-cells, the endocarp thin and crustaceous ; in Plagiospermum the budscales are replaced by persistent stipules, while the stamens are 2-seriate with contiguous anther-cells, and the endocarp is thick and stony. The material for our plate was supplied by Sir F. W. Moore from a plant of Plagiospermum sinense, which flowered at Glasnevin in February, 1916. This plant, supplied by Mr. T. Smith, Newry, came originally from Messrs. Regel and Kesselring, Petrograd. In March, 1916, another plant flowered at Kew for the first time. This plant was presented in 1908 by Mr. P. L. de Vilmorin, who had received it from Russia. In cultivation three somewhat distinct forms of P. sinense are met with. One of these has large leaves with relatively large flowers on long pedicels. The other two have smaller leaves and flowers; one of the two has fairly long, the other, here figured, has comparatively short flower-stalks, whence the name brachypoda. All are equally hardy out of doors in this country. Description.—Shrub, 6-7 ft. high, virgately branched; twigs of two kinds, the former long, strict, armed with spines, glabrous, clothed with last year’s y or whitish smooth bark, the latter rather contracted, bearing clusters of eaves ; the spines springing from above the short branches spreading, straight or slightly curved, some very short, others over } in. long. Leaves usually narrowly lanceolate, somewhat acute or obtuse, and often mucronate, base gradually narrowed to the petiole, entire, 2-1 in. long, 1-} in. wide, thin, quite glabrous, pale green above, glaucous beneath, nerves obscure; stipules of the leaves on the longer branches lanceolate-subulate, at length indurated, of those on the shorter branches thin, filiform, purplish, sometimes sparingly glandular. Flower arranged among the leaves of the shorter branches, orange-yellow ; pedicels in flower from }—3 in. long, or in the form brachypoda now figured only yo-s in. long, glabrous. Calyx wide-turbinate, } in. deep, pale, quite glabrous save for the cilia met with on the herbaceous teeth, clothed inside by a some- what fleshy disk with an annular opening. Petals orbicular, somewhat denti- culate, shortly clawed, 1-1 in. wide. Stamens 10, inserted on the disk-ring ; filaments as long as the small anthers. Ovary immersed in the base of the receptacle, depressed ellipsoid-globose, quite glabrous ; style lateral or in fruit almost basal, slightly exserted from the receptacle, gradually thickened upwards ; stigma depressed capitate ; ovules 2, collateral, spreading obliquely from the supra-basal placenta; micropyle almost occluded by a small adaxial caruncle.

The species here figured has been in cultivation in English gardens for more than two centuries. It is a small evergreen of very neat appearance, and when in fruit is singularly ornamental and pleasing. It is, more- over, perfectly hardy, and the single plant in the Rock Garden at Kew has grown there without any protection for the past twenty years. It thrives in either a light loamy or peaty soil and may be readily propagated by cuttings. In spite of these recommendations it is but rarely met with in collections and has been so little regarded that no horticultural figure appears to have been pub- lished. This is probably due to the fact that the plant is strictly dioecious, and that growers who have not been May, 1917, at pains to procure both sexes have not appreciated how attractive the female plant may be when in fruit. The plant is interesting as being that on which Linnaeus based the genus Myrsine; it is further interesting in having a geographical range much wider than is usual in the order Myrsinaceav. The original introduction to this country was from the Cape of Good Hope, and samples from that region were in cultivation at Hampton Court in 1691; to Cape specimens also the species owes its name WM. africana. Thence, however, it extends through tropical Africa to Afghanistan and Northern India. A figure based on a specimen from this region has been given in the Flora Simlensis of Sir Henry Collett. It occurs again in China whence it has been recently re-introduced; most if not all the plants in modern collections are of Chinese origin. The material from . which our plate was prepared was obtained in May, 1916, from the garden at Nymans, Handcross, Sussex, which contains one of the finest and most comprehensive collections of trees and shrubs in Britain, formed by the late Mr. L. Messel, and carefully maintained by his daughter. At Nymans two plants of M. africana of different sexes grow close together; this has resulted in the production of berries, hitherto a very rare event in this country. This, however, is not the first occasion on which J/. africana has fruited in England; it did so at Abbotsbury in 1893 and again in 1898, as specimens communicated to Kew in these years testify. Description.— Shrub, dioecious, 24-3} ft. high; twigs finely puberulous or nearly glabrous, brown. Leaves alternate, coriaceous, glabrous; petioles very short, blade 3-1 in. long, }—1 in. wide, lanceolate, obovate or elliptic, obtuse or acute, apiculate, base usually cuneate, margin sparsely toothed towards the apex, dark green and polished above, paler beneath.

The Horse Chestnut here figured is a native of Japan which is less often met with in collections than its merits deserve. Where it is grown it is not infrequently con- fused with its Chinese congener, Aesculus chinensis, Bunge, and in such cases the name may be further erroneously transcribed. Even when the fact that it is not the tree described by Bunge is appreciated, the practice has obtained of terming it A. japonica, a name for which there 18 no authority. The nearest ally of A. turbinata, June, 1917, oe the Japanese Horse Chestnut, is the European A. Hippo- castanum, Linn., itself ; from that familiar tree it is well distinguished by the smaller, obovate, and warted, but not spiny capsules, and by the finely and more evenly toothed edges of the leaflets. In its foliage A. turbinuta is the noblest of all the Horse Chestnuts ; young trees at Kew carry leaves which, with their stalks, are sometimes twenty-seven inches long. One merit of this Japanese Species is that it flowers somewhat later than the common Horse Chestnut. For the material from which our plate has been prepared we are indebted to Lieut.-Col. Sir George Holford. The tree from which it was gathered is growing close to his residence at Westonbirt, and is about thirty feet high, with a trunk two feet nine inches in girth, and a rounded crown of branches thirty feet across. This tree and another larger one at Westonbirt we believe to be the largest of their kind in the country. They were planted, Sir George informs us, by the late Mr. R. S. Holford about thirty-four years ago. In autumn the leaves turn clear golden yellow, then brown. These trees produce seeds from which young plants have been raised. Description.—Tree, at its largest 100 ft. high and 20 ft. in girth of trunk; bark of old trees scaling; winter buds very viscid; young shoots minutely ‘ pubescent. Leaves 5-7-foliate, deciduous; leaflets sessile, 4-15 in, long, 2-6 in. wide, the terminal leaflets more than twice the size of the basal pair; obovate- cuneate, shortly acuminate, finely serrate; deep bright green and glabrous above, glaucescent and with axil-tufts of pale brown tomentum beneath ; petiole 3-16 in. long. Panicles terminal, erect, slenderly pyramidal, up to 10 in. long by 3} in. wide at the base; rachis and pedicels finely pubescent. Flowers 2 in. in diameter, opening in late May. Calyx pubescent, campanulate, 5-lobed ; the lobes rounded, ciliate. Petals 4, subrotund with a narrow claw, reflexed, creamy-white with central-blotches of yellow which turn pink with age; pubescent above, ciliate. Stamens usually 7, much exserted; filaments slender, decurved, $ in. long. Ovary and style pubescent. Fruit an obovoid, 8-celled, leathery capsule, 2 in. in length and width, the thick 3-valved pericarp covered with brown warts. Seeds dark shining brown, 1-1} in. wide.

This fine Stauwropsis is remarkable for its exceptional size and its ample lax panicle of white flowers with violet blue markings on the lip. A native of the Solomon Islands, Kew is indebted for the plant to Sir Everard im Thurn, who met with it in 1905 when visiting that Archipelago on H.M.S. “ Torch,” as Governor of Fiji and High Com- missioner of the Western Pacific. At Langa Langa, on the west coast of Mala (Malaita) Island, an opportunity was afforded of botanising in the bush. In a forest with many large canopy trees but little undergrowth, the plant figured was found on a fallen trunk on which grew a dense mass of other orchids with ferns and grasses; it : bore the remains of a fairly recent flower-spike. On reaching Fiji it was planted on a topped tree fern under a “bush house” in the gardens of Government House. 1. wee It showed no sign of a new flower-spike until May, 1908. This spike was under a foot long in August, 1909, when a it began to develop more rapidly, but still showed no June, 1917, : : tendency to branch. In March, 1910, Fiji was ravaged by a violent hurricane. The Stauropsis was rescued from the “bush house” by Mr. D. Yeoward, Curator of the Fiji Botanic Station, and brought intact to the ruins of Government House, where it was fastened for safety underneath a billiard table. After the storm it was reinstalled on its old tree-fern stem, and during the next seven months its spike branched to some extent, and produced two rather poor flowers. In November, 1910, it was brought from Fiji by Sir Everard, and after a journey across Canada was sent from Liverpool to Kew, where it has since thriven well in the Tropical Orchid House, coming once more into flower in September, 1916. During flowering the prolonged development of the spike described by Sir Everard as regards 1903-10 has been equally manifest, but during 1914-16 branching has been more extensive. As in 1905 the plant gave evidence of having flowered during 1904, it is possible that in S. Imthurnii we may have a species which flowers only at definite periods. In keeping with this suggestion is the fact that in October, 1910, an imperfect dried specimen, accompanied by a sketch of a plant of this Stauropsis, was received at Kew from Mr. C. M. Woodford, then British Resident at Tulagi, Solomon Islands. Mr. Woodford found his plant in August, 1910, when the flowering period appeared to be nearly over, on the north side of Ysabel Island, and has noted that he had met with the species once before, but that on the first occasion it was not in flower. Description.—Herb, epiphytic; stem short, stout, erect, 14 in. thick. Laves arcuate, firmly coriaceous, elongate-ligulate, acute, 24-4 ft. long, 2-3 in. wide, imbricate and dilated at the base into stem-clasping sheaths.

The handsome Campanula here figured is a native of the province of Aidin in Asia Minor, where it has been collected in the neighbourhood of the ruins of Ephesus and Priene. Its nearest ally appears to be C. tomentosa, Vent., a native of Greece. The Ephesian plant is, how- ever, of more robust habit and has larger leaves and flowers than the Grecian one; the corolla in C. Ephesia, the subject of our plate, is from twice to thrice as wide as that of C. tomentosa, and is much less tubular in form. The introduction of this species horticulture owes to Sir J. N. Barran, Bart., by whom a living plant was brought to England from Priene, where it had been _ found by him in May, 1913. This plant was kept in a _ potin light soil, mainly sand, with some scraps of lime- - June, 1917, stone on the surface and lightly watered, in a cool house at Sawley Hall, Ripon, until the following summer, when it was transferred to an open alley roofed with glass. Under this treatment the plant throve well, and in 1915 it was possible to divide it, one of the plants so obtained being presented to Kew in February, 1916. From this example, which was grown at Kew in a pot of ordinary loam, and flowered there in a cool frame in June and July, 1916, the figure of C. Ephesia here given was pre- pared. A plant at Sawley Hall flowered synchronously with the example at Kew. While in flower the Kew plant was carefully pollinated, but failed to set any seeds; soon after flowering it died. Sir John Barran informs us that the plant which flowered at Sawley Hall did the same, but in this case a few seeds were developed and saved. There appears to be no record of any previous introduction of this species to English gardens ; whether its permanent establishment can be effected seems as yet doubtful.

Disanthus is an interesting genus of the Hamameli- daceae, established in 1866 by Maximowicz on the species now figured. So far as is known at present it is monotypic. From the other genera of this natural family, Disanthus is well dist nguished by the arrange- ment of the flowers, which are sessile and set, base to base, on two-flowered shortly peduncled capitula. D. cercidifolia is described by Sargent as being not rare in the Kisogawa valley in Central Hondo, covering steep hillsides with thickets sometimes a quarter of an acre in extent. It has been in cultivation about twenty years, but does not appear to have blossomed often. For the flowering twigs now figured we are indebted tv Mr. H. W. Grigg of Cann House, near Plymouth, where, in a very extensive and admirably cultivated collection of choice trees and shrubs, a healthy plant about 6 ft. high flowered last October. The flowers are of a lurid, un- JuNnE, 1917, attractive hue, and they have a faint, not pleasant odour; but the shrub, as our plate shows, has a real value for the rich autumnal tints of its foliage. At Kew it has, in this respect, proved one of the most attractive of newer shrubs. It likes a sunny spot and alight loamy or peaty soil. In the absence of seeds it can be increased by layers. The leaves depicted were drawn during the last week of October, 1916, and show the autumnal colouring. _Description.—Shrub, 6-10 ft. high, with slender, spreading branches ; twigs brown, glabrous, sprinkled with pale lenticels. Leaves deciduous, alternate, entire, quite glabrous, broadly ovate to roundish, cordate or truncate at the base, blunt or acute at the apex, 5-nerved, 2-4 in, long, nearly to quite as wide ; deep green in summer changing to a rich red suffused with orange in autumn ; petiole 1-2} in. long.

The Pine here figured is the Knob-Cone Pine of western North America which extends from the valley of the Mackenzie River in Oregon to the southern slopes of the San Bernardino Mountains in California. It occurs in somewhat isolated localities, often in fairly lofty and exposed situations, where its smaller size and inferior appearance have given rise to the alternative name of Scrub Pine. A remarkable feature of the species in all its localities is the indefinite persistence of its tightly closed cones. Jepson records a limb, five and a half feet long, secured by him in the Santa Lucia Mountains, California, bearing forty-five cones ; in the Museum at Kew is preserved a portion of a branch, four feet long, from a tree grown at Bayfordbury, which carries more than forty cones. The seeds thus imprisoned by the scales retain their vitality for many years, and it has been said that cones never discharge their seeds until the tree, or a least the branch on which they are borne, dies. This is not always the case, for after some successive days of great heat cones that are four or five years old may open and allow their seeds to fall. Ordinarily however, the cones remain unopened until subjected to the heat resulting from a forest-fire, when the scales come apart and the seeds thus liberated afforest the devastated area. When first discovered by Hartweg in 1847 in the Santa Cruz Mountains, California, the Knob-Cone Pine was mistaken for that form of the Monterey Pine, P. radiata, D. Don, to which Don had given the name P. tuberculata, and when Gordon drew up his account of this tree his descri ption included along with it the tree which Don had named P. tuberculata. Lemmon, who first set matters right, proposed the name P. attentuata for Hartweg’s tree ; most authors, however, have preferred to accept the transfer of the name P. tuberculata to the Knob-Cone Pine. The material for our plate was provided by a tree in the Pinetum at Kew, one of a pair planted by Sir J. D. Hooker some forty years ago; though quite healthy and perfectly hardy these are sigieiaiee” as now only about twenty-five feet high. From what has been said above it would appear to be necessary, if seed for propagation is to be obtained from cultivated trees, to expose the ripe cones for a short time to considerable heat. Description.—T ree, usually 20-25 ft. high, with a trunk 1 ft. in diameter, occasionally reaching 80-100 ft. in height and with a trunk twice as thick ; branches somewhat spreading to form a broadly pyramidal crown which becomes thinner and flatter with age; bark~at first smooth and brown, with age blackish and peeling in broad flakes. Wéinter-buds cylindric, 3-1 in. long, ? in. across, chestnut-brown or purplish, ‘resinous; bud-scales with the exception of the lowest closely appressed, lanceolate, subulate-tipped, rather deeply and freely fimbriate. Leaves in clusters of threes, encircled at the base by hyaline-scarious sheathing scales which are at first brownish but ultimately tawny or grey; individual leaves acicular, almost pungent, 3-7 in. long, ; in. wide, with very finely serrulate edges, rigid, pale or dull green, convex on the back, furrowed when dry between the midrib and margins along the face. Male cones cylindric, about 2;in. long, + in. wide, chestnut-brown. Female cones aggregated in clusters of 2-4, in flower ovoid- or ellipsoid-globose, 1-2 in. long. Carpels rounded-ovate, even in flower much shorter than the ovuliferous scales, which are wide ovate, thickened upwards and abruptly spinulose at the tip. Cones when ripe deflexed and often closely appressed to the branches, in outline obliquely elongate-ovate or ovate-oblong, 3-6 in. long, 1-2} in. thick, chestnut brown; ripe scales spathulate-cuneate, very close-set, woody, the central on the outer face of the cone 13-2 in. long, } in. wide near the top, those on the inner face of the cone much smaller; hypophysis rhombic with a fine transverse keel; umbo shortly incurved, spinescent from a broad base. Seeds obovoid, } in. long, blackish, broadly winged ; wing oblique at the apex, 3-1 in. long, 3-3 in. wide, white or brownish, marked with thicker and finer reddish es.

Ronre, The handsome QOdontoglossum here figured is a native of Guatemala, originally described as O. platycheilum from a solitary plant which had flowered in March, 1892, in the collection of Mr. R. I. Measures of Camberwell. The county of origin of that example was then unknown ; all that was known regarding it was that it had been acquired along with some other orchids when the Downside collection was dispersed. More than a decade later a specimen of the same species were received at Kew in a collection of dried plants communicated by Mr. J. Donnell Smith. This specimen had been gathered by Heyde and Lux in April, 1892, at an elevation of 8,800 feet, at Chiul in the department of Quiche, Guatemala; it is now known that a fruiting specimen collected by Bernoulli in Guatemala in May, 1860, belongs to the same species. In 1905 Messrs. Sander and Sons, St. Albans, were able to make an importation of this Odontoglossum, which since then has flowered fre- Juxy, 1917, quently in various collections. The material for our figure has been derived from a plant purchased from Messrs. Sander, which has thriven well under the con- ditions suitable for O. crispum and has flowered annually in May.

This free-flowering little Gesnerad was discovered by Mr. George Forrest on the eastern flank of the Lichiang Range in North-Western Yunnan. The plant was met with on mess-covered boulders and on branches of trees in very shady situations at an elevation of from 10,000 to 11,000 feet. Mr. Forrest sent seeds to Messrs. Bees, Ltd., from whom some were received at Kew in 1913. One of the plants raised from these, which flowered in a cold house in May, 1915, furnished the material for the accom- es . panying figure. At Edinburgh it has been in cultivation _ Since 1909 and there it flowers freely. It is not yet clear Juxy, 1917, whether the species be hardy at Kew, but it may survive a mild winter out of doors if protected from excessive moisture. In habit it much resembles /eamondia pyrenaica, Rich. Though originally described as a oetilera, in which some authorities merge the genera Didymocarpus and Chirita, the structure of the flower indicates its true position as a species of the closely allied genus Oreocharis. The salient character by which Oreocharis may be distinguished from Didymocarpus, Chirita and Didissandra is in the four fertile stamens, the anthers of which are not coherent or even connivent. Dr. Diels described Roettlera Forrestii as having two fertile stamens with staminodes, the number of which is not stated. What were regarded as staminodes were fertile stamens from which the anthers had fallen, the real staminode. a very small minute body, being overlooked. Through the kindness of Professor Bayley Balfour it has been possible to compare and identify the Kew plant with the excellent specimens of Hvettl ra Morrestii collected by Mr. Forrest and now preserved in the Herbarium of the Royal Botanic Garden, Edinburgh. The genus Oreocharis now includes about twenty species, all of which, excepting V. notha, C. B. Clarke, from the Philippine Islands, and O. primulvides, Benth. & Hook. f., from Japan, are Chinese.

The genus Sinofranchetia is a member of the Lardiza- baluceae, a group of forms treated in the Genera Plantarum as a distinct tribe of the natural order Berberidaceae, but regarded in the Natiirlichen Pflanzen- familien as a distinct family. The solitary species, S. chinensis, is a vigorous climber with inconspicuous flowers, but with showy and striking lavender-purple fruits, which appears to be common at altitudes of 5,000- 9,000 feet in western Hupeh and Szechuan. Its botanical history has been somewhat confused. In 1889 the late Professor Oliver based a new Holboellia, H. cuneata, on male and female specimens obtained by Mr. A. Henry in Hupeh, pointing out, however, certain differences, besides that of sex, in the two components of the species. The JuLy, 1917, late Mr. Franchet in 1894 described as Parvatia chinensis a species collected by Farges in Szechuan. In this Parvatia Professor Diels recognised the female portion of Holboellia cuneata, Oliv., so distinct from the male portion as to belong to a different subgenus of LHolboellia. To this subgenus, which Diels had termed Sinofranchetia, the rank of a genus was accorded by Dr. Hemsley in 1909. It has now been discovered that the male portion cf Holboellia cuneata, Oliv., is also better considered as belonging to a distinct genus, a female of which has been met with in western Hupeh by Mr. E. H. Wilson. This new genus is now known as Sargentodora, Rehder & E. H. Wilson, also a member of the Lardizabalaceae. The material for our figure of Sinofranchetia chinensis has been derived from the collection of Miss E. A. Willmott, Warley Place, by whom fruiting sprays were communi- cated in November, 1915, specimens with male flowers being sent in June, 1916. At Warley Place Sinofranchetia was raised from seed in a cold frame, and in the second year was planted against a pergola in a north-east position. A year later flowers appeared and fruit ripened. It has proved perfectly hardy and has been unscathed by the severe winter of 1916-17. It is not fastidious as regards either soil or position, it calls for no special treatment, and may be propagated by seed.

Hutcurson, i This handsome Rhododendron was originally met with by Lady Wheeler Cuffe, to whom it is dedicated, on Sindaung, or ‘“ Elephant Hill,” a great outlying mass, whose summit is 6,000 feet above sea-level, on the edge of the Shan plateau in Upper Burma. &. Cujfeanum is closely related to R. Dalhousieae, Hook. f., a species which extends from Sikkim through Bhutan to Manipur, but differs from that species in having its calyx-lobes lepidote outside and fringed with long weak hairs. It is more remotely allied to R. Nuttallii, Booth, from Bhutan, and to &. crassum, Franch., from Yunnan, both of which have calyx-lobes that are neither lepidote nor Aveusr, 1917, fringed with hairs. Young plants of this and some other species from Sindaung were presented by Lady Wheeler Cufie in August, 1913, to the Royal Botanic Gardens, Glasnevin. From one of these, which flowered in May, 1915, came the material on which our figure is based. Sir Frederick Moore, to whom we are also indebted for a photograph from which the sketch of the entire plant has been prepared, informs us that in some of the examples the basal swellings are much larger than in the one figured. The establishment of the plants proved slow, but after twelve months in moist heat in shade it was possible’ to remove them to a cool orchid house where in a deep shade they thrive well. A year later they were transferred to a cool greenhouse, with a night temperature of 45° F., and with ample ventilation. Here they have flowered and by their behaviour afford hope that they may even be hardy out of doors in the milder parts of the United Kingdom. They have been grown in ordinary heavy peat, and when once they are well established their cultivation offers no difficulty. One of the distinguishing features of J. Cuffeanum is its fragrance. Descrietion.—Shrub, loosely branched; stem swollen at the base; new shoots pale grey, beset with brown sessile peltate scales; older pale-brown, closely marked with the traces of fallen scales. Leaves few, widely scattered, evergreen, oblanceolate, gradually and shortly acuminate to an obtuse tip, base somewhat gradually narrowed, up to 4 in. long, 12 in. wide, coriaceous, at first sparingly glandular-lepidote above, at length glabrous and distinctly reticulately nerved, below paler and densely glandular-lepidote, the scales small, brown, unequal in size and discrete; mid-rib sunk above, slightly raised beneath ; lateral nerves 6-7 along each side, slender, flexuous,’ slightly raised on both surfaces ; petiole about 4} in. long, compressed, closely lepidote.

It was originally described by Dr. C. K. Schneider as . aggregata from a flowering specimen collected by Potanin in Eastern Kansu with which he associated a fruiting specimen gathered by E. H. Wilson in Szechuan. It was at first placed by its author in the section Sinenses next to B. Wilsonae, Hemsl. Subse- quently, however, the opportunity of studying further material obtained by Wilson in Szechuan, induced its author to transfer B. aggregata, on account of its inflorescence, to the section Polyanthae. The material for our plate has been obtained from a plant raised at Kew in 1911, from seed purchased from the Arnold Arboretum which had been collected by Mr. Wilson in October, 1910, in the Min Valley, Western Szechuan. As Aveust, 1917, : an addition to outdoor collections B. aggregata possesses the merit of being ornamental both when in flower and when in fruit, but more especially in the latter condition. It is evidently perfectly hardy, thriving well in a sunny spot planted in a loamy soil; its abundant seed renders its propagation easy.

The distinct and attractive Bulbophyllum here figured is one that has long been in cultivation. At Kew when grown in a teak-basket under tropical conditions it is easy to manage and rarely fails to flower freely. It was long believed to be a variety of B. Careyanum, Spreng., and in many collections has been grown as B. Careyanum roseum. It was first recognised as a distinct species in 1896 by Mr. H. N. Ridley, and was originally described by him from material collected by himself on Kedah Peak in the Malay Peninsula and by Mr. C. Curtis in southern Siam. When naming it B. lilacinum Mr. Ridley indicated its affinity to B. Pechei, Bull, a native of Moulmein, figured at t. 7286 of this work. These two species differ in the colour of their flowers; both are equally closely related to B. Careyanum. The date of Aveust, 1917, its original introduction is uncertain. It seems to have been added to the collection of the late Sir Trevor Lawrence, Burford, Dorking, in or before 1898; in November of that year it was submitted by him to Kew for identification, with a note that it has been bought from the collection of the Hon. Walter Rothschild at Tring, but that its native habitat was unknown. This plant, which flowers regularly each autumn, was pre- sented to the Kew collection by the late Lady Lawrence ; our plate was prepared from it when in flower in November, 1915. Description.—Herb, epiphytic ; rootstock creeping, rather stout and woody; udobulbs rather close-set, ovoid or at times oblong, 1-2 in. long, clothed low with membranous sheaths, 1-foliate.

The Polygonum we figure here was discovered by Dr. W. Griffith in 1837 growing on rocks above Sanah, in Bhutan, at about 10,000 feet above sea-level. The plant remained undescribed until 1886 when Sir J. D. Hooker named it P. Griffithi. The species was not heard of again until 1904 when it was met with by Mr. G. Forrest in moist mountain meadows on the eastern flank of the Mekong-Salween Divide in south- western Yunnan, at altitudes of 9,000—-11,000 feet. It had already been gathered by Pére Monbeig at Tse-kou in the same province, specimens gathered by him reach- ing Kew in 1905. Since then Mr. F. K. Ward has also collected this species in Yunnan. The material for our plate was provided by a plant raised from seeds received at August, 1917, Kew in 1914 from Messrs. Bees, Limited, under the unpub- lished name P. kermesinum which is now current in some collections. At Kew the plants reach a height of eighteen inches and flower early in August; though quite hardy they have failed so far to mature seeds. They form a distinct addition to the Rock Garden, . striking because of the numerous spikes of rich crimson flowers. P. Grifithii approaches most closely P. sphaero- stachyum, Meisn., figured at t. 6847 of this work, which differs in having usually solitary smaller spikes on longer peduncles in the axils of narrower cauline leaves. While P. sphaerostachyum has short and often recurved pedicels, P. Grifithii has long erect ones. For this reason the bracts which are closely imbricate around the central axis become visible in P. Griffithii, and by their buff colour provide an effective contrast with the rich red of the perianth. The leaves of P. Grifithii are in wild specimens firm and almost leathery, in cultivated plants usually much thinner in texture. Descriprion.— Herb, perennial; branches tufted, about 12 from each woody stock.

This handsome Odontoglossum was originally discovered by Warscewicz on the volcano of Chiriqui in Costa Rica, at 9,000 feet above sea-level; it was first described by Reichenbach, from herbarium specimens, in 1852. Its introduction to cultivation did not take place until thirty years later when it was imported by Messrs. Sander and Sons, St. Albans. The locality was not then recorded, nor was it known in July, 1890, when an inflorescence was sent to Kew for determination by Messrs. E, Vervaet and Company, Ghent. In 1894 Mr. R. Pfau sent a photograph and a dried specimen _ from San Jose, Costa Rica. It now appears that the _ Species also occurs in Colombia; there is, in the collection SErremper, 1917, of the late Consul F. C. Lehmann, a dried flower stated to be from Yarumal, in the province of Antioquia. The material for our figure of O. chiriquense has been derived from a plant acquired for the Kew collection at the Red Cross sale held in 1916. Until then this plant had been for upwards of twenty years in the collection of Mr. W.G. Grove, Holehird, Windermere. At Kew it flowered in October. It thrives well in a house suitable for species of Miltonia, the Odontoglossum house being too cold in winter for this species. It makes vigorous growth in a compost of peat fibre and sphagnum and requires a liberal supply of water. The nearest ally of O. chiriquense is O. coronarium, Lindl., figured at t. 7687 of this work, of which it has been regarded as a variety, but from which it is readily distinguished by its larger and very undulate flowers.

The genus Oresitrophe includes only one_ species, O. rupifraga, which was first described by Dr. Bunge in 1834 from material collected by himself in clefts of rocks on the mountains near Lun-zuan-ssi and Ssi-jui-ssi in Northern China. It was regarded by him as nearly allied to Astilbe, Ham., though in habit very different from that genus. In the family Savifragaceae it 18 certainly somewhat anomalous, though in floral structure it agrees best with Chrysosplenium, Linn.; in habit, however, it is as remote from this genus as it is from Astilbe. Subsequent to its discovery by Bunge, it was again collected on Mount Poa-hua-shan, near Pekin, by Dr. Bretschneider; still later it was collected on the western hills near Pekin by Mr. W. Hancock, who has noted it as confined to rocky gullies, and as being rare. More recently it has been met with again by Mr. F. N. Meyer, in crevices of rocks in the Nankow Pass, Chibli, SEPTEMBER, 1917, in northern China, to whom its introduction to horti- culture is due. Struck by its suitability as a rockery plant, Mr. Meyer sent rootstocks to Kew, as those of a species of Savifraga, in 1913. Since their arrival these aaah have been kept in pots in a cold frame. They ave thriven satisfactorily and flowered freely both in 1915 and 1916, when our drawing was prepared. Though it has not yet been planted out, 0. rupifraga promises to be quite hardy at Kew. The leaves, in autumn, turn brown-purple. Description.—Herb, stemless ; rootstock thick, scaly, growing in clefts of rocks.

Hurcursoy, ao The charming Rhododendron here figured appears to be confined to the Tali range in Yunnan where it was originally discovered by the Abbé Delavay a generation ago. It has been repeatedly met with on the same range by Mr. G. Forrest, at altitudes of 9,000-11,000 feet. Plants have been raised by Mr. J. C. Williams, Caerhays Castle, Gorran, Cornwall, from seed collected by Mr. Forrest, and from one of these came the material for our plate. Mr. Williams informs us that 2. neriiflorum, which has now been in his collection some six years, SEPTEMBER, 1917, : grows both well at Caerhays and at Werrington, near Launceston, which is colder than Caerhays. It is a dwarf shrub which begins to flower when less than eighteen inches in height ; even in the wild state it does not exceed five feet in height. According to Forrest the flowers vary in shade from deep rose to crimson scarlet and as grown in this country it provides brilliant patches of colour. It has proved easy to grow and has the advantage of thriving well in more open spaces than the Indian species whose flowers are of the same rich colour. ft. neriiflorum belongs to a group of species in the section Hurhododendron characterised by their smooth eglandular leaves. Among these it is readily distinguished by the — pinkish glaucous, finely reticulate under surface of the leaves, the crimson calyx, and the glabrous filaments. It does not appear to be closely related to any other Chinese species, and is only remotely allied to the Sikkim £t. Thomsoni, Hook. f., figured at t. 4997 of this work. In R. Thomsoni the corolla is of the same colour, and the under surface of the leaves has the same glaucous bloom, but the leaves in the Sikkim plant are cordate at the base and more orbicular in outline, while the ovary is quite smooth, not hairy as in R. neriiflorum.

Aster fuscescens is a species originally discovered in 1889 by the late Abbé Delavay, in the Tsang-chang mountains, Yunnan. It was met with again in 1890 near Ta-chien-lu, in Szechuan, by Prince Henri d’Orléans and Mr. Bonvalot, and was first described from their specimens. The species bears considerable resemblance to the well-known A. scaber, Thunb., which also occurs in Yunnan and Szechuan, but extends thence northwards as far as Corea and Japan. From that species A. fuscescens differs in its more rounded leaves, its less winged petiole, and particularly in the linear-lanceolate, acutely acuminate, © glandular-puberulous bracts of the involucre; the flower- — _ SEPTEMBER, 1917. | ' heads of A. fuscescens are moreover distinctly larger than these of A. scaber. The plant figured was grown from seed presented to Kew in 1914 by Messrs. Bees. These seeds had been collected in western China by Mr. F. K. Ward. A hardy perennial which grows vigorously and ripens its seeds freely in a herbaceous border, A. Juscescens is well worth cultivating. At Kew it reaches a height of about two feet. Descriprion.— Herb ; stem simple, up to 2 ft. in height, stout, } in. thick, ridged, pubescent with crisp rather reflexed hairs.

Colwmna clavata, 3 cm. longa.—R. A. Roure. This pleasing Pleione is a native of Formosa, where it was discovered by Mr. W. R. Price, during the joint expedition to that island by Mr. H. J. Elwes and himself. In 1914 pseudobulbs were sent by Mr. Price to Kew, where they produced flowers in the following spring. It was at first believed that the species might prove to be P. formosana, Hayata, a native of the same island first described in 1911, of which there is no specimen available for comparison. The description of P. formosana, how- ever, indicates that in that species the stems are ten inches high with racemes of two to three flowers, bracts over an inch and a half in length and a 4-lamellate in place of the 2-lamellate lip-disk met with in P. Pricei. The figure now given has been prepared from the plants received at Kew from Mr. Price, but it has to be noted _ that another plant, which flowered in the collection of _ Mr. Elwes at Colesborne in April, 1917, produced a flower OctopeER, 1917. of a rather darker rosy-lilac shade with the bract more distinctly lined with red. The species has thriven well in a tropical house under the conditions and treatment suitable for the Indian P. Hookeriana, which it resembles, figured at t. 6388 of this work as a Coelogyne. Description.—Herb, terrestrial; pseudobulbs wide-ovoid or depressed-ovoid, olive-green, when old obscurely angled, 3-8 in. across, 1-foliate, clothed with acute membranous sheaths. Leaves immature at time of flowering, elliptic- lanceolate, acute, 13-2 in. long, when full grown up to 9 in. long by 1} in. wide.
