The interesting Begonia which forms the subject of our illustration was obtained for the Kew collection in 1907 from Messrs. Haage & Schmidt, Erfurt. It occupies a some- what isolated place within the section Knesebeckia, yet while this is its most satisfactory systematic position as the species of this extensive genus are at present classified, it bears a striking resemblance to B. maculata, Raddi, a species which belongs, however, to the section Gaerdtia, in which the two segments of the placenta bear ovules on their outer surfaces only. The most natural explanation of this
January, 1912.
peculiar combination of characters that can be suggested is that B. dichroa may be a hybrid between two species belonging to different sections. Yet in the present instance this explanation is perhaps not the true one, because B. dichroa has matured seeds at Kew, and the resulting plants have proved to be exactly like the parent one. it is, however, just possible that too great stress has been laid on the character afforded by the circumstance that the Segments of the placenta bear ovules on one side only, or on both surfaces. B. dichroa is a species that requires tropical conditions. It has large leaves and is of a some- what lax habit; for a Begonia its growth is slow. The flowers, which are produced in spring, are remarkable for their shining orange-scarlet colour, a tint unlike that of any of the other cultivated species included in the group known in gardens as shrubby Begonias.
Descriprion.— Herd, tall, with minute seattered beaded glandular hairs on the young shoots and inflorescence, otherwise glabrous. Leaves in young plants rhomboid- elliptic, semicordate, acuminate, 4-5 in. long, 2 in. wide or rather wider, blotched with white; in full-grown plants ovate-oblong, sharply acuminate, base semicordate but very oblique, 8-nerved with the lowest pair small and incon- spicuous, higher up with the nerves again pinnately 3—5-nerved on each side, 9-12 in. long, 43-53 in. wide, margin slightly undulate ; deep green above, somewhat polished, pale beneath ; petiole $-2 in. long; stipules ovate, sharply acuminate, 1 in. long, 7 lin. wide.

The beautiful shrub or small tree which forms the subject of our illustration is confined naturally to a small area in northern Georgia which extends across the Savannah River into South Carolina. Within this limited tract it is rare or at least local in woods, especially along rivers. The species was first received at Kew in 1894 from the late Mr. P. J. Berckmans, of Augusta, Georgia, who sent some pieces with a little root attached, accompanied by a note recording his having first noted it when botanising with the late Professor A. Gray some thirty years previously, Unfor- tunately none of the pieces grew, and it was not until 1902, when two well-rooted plants were again sent by Mr. Berckmans, that Elliottia racemosa became established in the Kew Collection. One of the plants has been injured
January, 1912.
as the result of attempts to propagate the species by root- cuttings; the other has grown well, and is now a shrub about seven feet high, which flowered for the first time in July, 1911. The two plants are situated in a bed of heaths where, to the ordinary sandy soil of Kew, have been added a little peat and some leaf soil. Conditions suitable for Rhododendrons and the Heath family generally appear to suit the Elliottia exactly. The great difficulty with this species is to propagate it; although the stigmas were carefully dusted with pollen and the flowers attracted many bees, not a single fruit was developed. Ordinary cuttings of the twigs have been tried several times without success. Layering is now being tried, but grafting, which suggests itself, seems excluded owing to the difficulty in finding a suitable stock.
Drscriprion.—Shrub, or small tree, 20-24 ft. high, twigs virgate, when young slender, pubescent, chestnut-brown, later orange-tawny, ultimately grey-tawny and glabrous. Leaves alternate, oblong or elliptic-oblong, acute, base cuneate, 23-4 in. long, 1-14 in. wide, membranous, dark green above, glabrous, pale and loosely pilose beneath ; petiole dilated below, pubescent, 4—5 lin. long. Inflorescence terminal, racemose or almost paniculate, 6—10 in. long, lax ; bracts and bracteoles lanceolate or subulate, scarious, semi- deciduous ; pedicels slender, 5—7 lin, long. Calya flatly cupular, about 2 lin. across, reddish, 4-lobed, the lobes rather broad, cuspidate and ciliolate, but otherwise glabrous. Petals 4, white, slightly cuneate at the very base, narrow spathulate oblong, 5-6 lin. long, under 2 lin. wide. Stamens 8; filaments 24 lin. long, linear; anther 2-lobed below, oblong-lanceolate, over 1 lin. long. Ovary resting on a thick 4-lobed disk, depressed, 4-celled ; style filiform,
thickened and incurved above, 4 lin, long ; stigma obliquely capitate. Lruit unknown. ;

Thunbergii similis, differt spinis infra foliorum fasciculos 3, foliis crassissimis eximie reticulatis flores excedentibus et floribus numerosis minoribus in racemos congestos dispositis.
Fruier, tarde deciduus vel fere sempervirens, ad 1 m. altus, patulus; ramuli graciles, angulati, minute brunneo-pubescentes. Folia fasciculata oblanceo- lata vel anguste obovata, sessilia, apice rotundata mucronata vel subacuta, casu 3-partita, basi sensim attenuata, 0°6-2°5 em. longa, 2-6 mm. lata, pallide viridia, supra opaca subtus glauca, conspicue reticulata; fasciculi in axillis spinarum 3-fureatarum dispositi; spinarum rami aciculati 1-2 cm. longi.

Stamina petalis breviora. fructus globosus, 6 mm. diametro, pallide puniceus.—W. J. BEAN.
Among the many new forms belonging to the genus Berberis which recent exploration in China has disclosed, the subject of our plate is one of the most distinct and attractive. It is a native of Central and Western China, and was first met with by Mr. E. H. Wilson when collecting on behalf of Messrs. J. Veitch & Sons in the neighbour- hood of Tatien-lu in 1903. The material for our figure las been derived from a plant presented to the Kew collection by Messrs. Veitch in 1907. But while very different from any of the species formerly known in gardens, B. Wilsonae appears to be one of aseries of variable forms from the same general region rather than an isolated and well differentiated species. This conclusion is the result of an examination of a number of Chinese Barberies, palpably of the same type of B. Wilsonae, though noticeably different in their details, recently intro- duced to cultivation at Kew, Coombe Wood and elsewhere, Perhaps the most nearly allied of these forms is one which has been described as ZB. parvifolia, Sprague. Another form almost if not quite identical with B. Wilsonae was _ Janvary, 1912.
collected in Yunnan by Pére Ducloux: his specimens are not definitely dated, but it is known that they were obtained some time prior to 1901. If B. parvifolia can be regarded as no more than a variety of the species to which B. Wil- sonae belongs, then this species has been in cultivation at Kew since 1896, when seeds were received from St. Peters- burg. As a garden plant B. Wilsonae has attractions in its flowers, which appear during July and August; in its fruit, which ripens in October ; and, according to Wilson, in the brilliant autumnal tints of its foliage. It is, how- ever, necessary to remark that, at Kew, the last-mentioned characteristic has not been strikingly manifested ; indeed, the young plants grown here have shown a marked tendency to retain much of their foliage thronghout the winter. The dwarf, spreading habit of the plant renders it suitable for the rock-garden in a sunny position where its branches can overhang some miniature cliff. It prefers a loamy soil and is very easily increased by means of seeds.
Derscription.—A deciduous or sub-evergreen shrub of low, spreading habit, 2 to 4 ft, high; branchlets slender, Zig-7ae, angled, clothed with a minute, dark-brown pubescence. Leaves in fascicles produced in the axils of triple-forked spines, each fork acicular, = to Zin. long; oblanceolate or narrowly obovate, sessile, the apex rounded, mucronate or somewhat acute, or occasionally tripartite, 4 to 1 in. long, ys to } in. wide; dull greyish-ereen above, more or less glaucous beneath and conspicuously net-veined. Flowers bright golden-yellow, § In. in diameter, in fascicles or shortly stalked umbels. Sepals 6, obovate-orbicular, 4! to s In. Jong.

The interesting South African Orchid which forms the subject of our illustration is one of the “ blue” Disas, which are sometimes looked upon as belonging to a distinct genus Hlersehelia, Lindl, According to the late Mr. Bolus, who first described the species in 1884, our subject is by far the tallest and strongest member of the Herschelia group which is here treated as a distinct section. This species was, prior to its differentiation by Dr. Bolus, confused with the nearly allied D. barbata, Sw., but is readily distinguished by the metallic greenish-purple hue of its flowers; those of D. barbata are white, lined with blue on the dorsal sepal. D. /ugens grows on the Cape Flats, in moist sandy soil among festiaceae, at an elevation of about 100 feet above sea level, and flowers there in the months of October and November. From this
January, 1912.
locality it extends eastward as far as Coldstream, near Grahamstown. Though the species has been repeatedly introduced to cultivation in this country, it is by no means easy to maintain in good condition, owing to its tendency to dwindle away after flowering. It thrives most satisfac- torily when grown as a greenhouse-plant in a cool, airy, sunny position in a mixture of equal parts of sand, peat, loam and charcoal. The growth of the tubers commences in autumn, and when the plants have become well established and are in full growth they require an abundance of water at the root. After the flowers have appeared the plant commences to die down. The supply of water should then be gradually reduced until growth ceases. Then the tubers
should be kept quite dry for a period of from two to three months.

In the most recent monograph of the genus Calceolaria Dr. Kraenzlin has recognised about two hundred species, all of them confined to the American continent, where they extend from Mexico through Central America to South America, and occur also in the Falkland Islands. In the case of the solitary Peruvian form with triandrous flowers, C. triandra, Vahl, the treatment proposed by G. Don has been followed and the plant is recognised as the type of a distinct genus Porodittia, @. Don; while the four New Zealand species, to which have to be added two from Chile and Peru, with ringent but not calceolate lips, have been placed by Kraenzlin in a distinct genus, Jovellana. With very. few exceptions the species referable to the restricted
January, 1912. :
genus Calceolaria are found only on the western side of the American continent. They are concentrated more especially in Peru and Chile, the number of species in Peru being about ninety-four, in Chile about seventy-five. Each country has fifty-eight species peculiar to itself; only nine species are common to both. The species which forms the subject of our plate is one of those peculiar to Chile, where it has been collected by Mr. H. J. Elwes as far south as the Bafios de Chillan in Nuble at 5-6,000 feet above sea level, and by Professor Philippi as far north as the province of Coquimbo. The plant from which our figure has been prepared is one of several raised from seed purchased in October, 1910, from Mr. J. D. Husbands, Limavida, Chile. Grown in a pot in a cool frame, it has formed suberect stems about four inches long, some of which have developed terminal erect slender scapes about a foot anda half in length that continued to bear flowers from June till October. The flowers, which are distinctly violet-scented, have hitherto been stated to be yellow, doubtless the result of descrip- tions based on dried specimens in which they soon become yellowish or brownish-white; they are, however, usually purple, less often rose coloured. The plant, which appears to be a perennial, might easily be mistaken, when not in flower, for a Stachys or a Gnaphalium. The nearest ally of C. cana is C. arachnoidea, Grah., figured at t. 2874 of this work; that species, however, differs from C. cana in being usually more robust and more woolly and in having much larger cauline leaves, with purple self-coloured flowers devoid of the markings which characterise those of C. cana.
Description.—Herb, perennial, tufted, rather small,
scapose. Leaves radical, close set, oblong-lanceolate, spa-
thulate or obovate, 14-2} in. long, 2-3 in. wide, subacute
or obtuse, gradually narrowed to a broad often short petiole, entire or finely toothed, more or less densely white woolly. Scape slender, erect, including the inflorescence 1-1} ft. long, cylindric, sparingly pilose or nearly glab- rous, often bifurcate upwards, with a few small linear oblong leafy bracts, 3-4 lin. long. Inflorescence open, at first almost corymbose, cymosely branched, the branches ultimateiy elongated, raceme-like, 2-6 in. long, more or less glandular pubescent. Pedicels very slender, 4-5 lin.
Jong. Flowers violet-scented. Calyx about 2 lin. long, glandular-pubescent, lobes ovate, subequal, about 1 lin. wide. Corolla white, distinctly marked with small purple or rose-coloured blotches and lines, often more or less suffused throughout with rose or purple; throat yellow, with larger purplish-brown blotches; upper lip hooded, about as long as the calyx; lower lip ellipsoid-globose, about 5 lin. long, 3-4 lin. wide; mouth obovate, 2-24 lin. across. Stamens very short; filaments sparingly glandular- pubescent. Ovary densely glandular puberulous, slightly shorter than the calyx. Capsule densely glandular- puberulous, shortly beaked, 2-24 lin. long.

NOTICE OF RE-ISSUE.
Some portions of the above work being out of print, and complete sets very difficult to obtain, the Publishers have determined to reprint so much as will enable them to complete a few copies as they may be subscribed for ; and to meet the convenience of Subscribers, to whom the outlay at one time of so large a sum as a complete set now costs is an impediment to its purchase, they will commence a re-issue of two Volumes Monthly, thus spreading the cost over a period of two and a half years. The price of the volumes will be 42s. each as heretofore, but to Subscribers for the entire series 36s. each, or a complete set of the 60 vols. will be supplied for £100 cash. Subscribers may commence at any time.
The BoranicaL MAGAZINE, commenced in 1787, and continued with uninterrupted regularity to the present time, forms the most extensive and authentic repertory of Plant History and Portraiture extant. The Turrp Serres, by far the most valuable, comprising all the important additions of the last sixty years, contains nearly 4000 Coloured Plates, with Descriptions, structural and historical, by Sir William and Sir Joseph Hooker.
A set complete from the commencement in 1787, including the First, Second, and Third Series, to the end of 1904, 180 vols., may be had, price £136.
N.B.—A Fourth Series commenced in January, 1905, and is edited by D. Prain, C.1.E., LU.D., F.R.S., Director of the Royal Botanic Gardens, Kew.

‘The handsome Stanhopea here figured was discovered in Peru by Mr. Forget when collecting on behalf of Messrs. Sander & Sons, St. Albans, to whom Kew is indebted for the plant which forms the basis of our plate. This plant was presented by them to the Kew colleetion in 1909, the year of its first importation. It has thriven well in the Cattleya House and flowered for the first time in January, 1910. It is allied to the Mexican S. Wardii, Lodd., but has smaller flowers with narrower petals, while the hypochile of the lip differs materially in shape and is not distinctly angled at the base. It may also be eompared with S. Shuttleworthii, Reichb. f., but that species again has larger flowers, while the hypochile of the lip is broadly expanded at the base. S. peruviana is remarkable for the unusual width and almost board-like firmness of its dark-
green, plicate leaves. As in most other species of the genus the flowers, which in S. peruviana are very fragrant,
ast for only a few days. Fesrvary, 1912.

Frutex vel arbor in patria ad 9 m. alta, ramulis adpresse hirtis vetustis cortice plumbeo vel cinereo tectis. Folia lanceolata vel oblanceolata, in eadem ’ planta valde variabilia, basi acuta vel subacuta, rarius obtusiuscula, apice acuta, breviter acute acuminata vel interdum obtusiuscula, inte- gerrima, 3°5-10 cm. longa, 1°5-3°5 ecm. lata, coriacea, viridia, infra pillidiora et plerumque ab initio glaberrima, supra in costa et ad margines primo pubescentia, saepe quasi lineis argenteis notata, deinde magis minusve glabrescentia, nervis utrinque 7-12; petioli 10-15 mm. longi, supra canaliculati et magis minusve—interdum dense—hirto-pubescentes ; stipulae subulatae, 6-11 mm.

The Stranvaesia which is here depicted, owing to the fleeting nature of its-blossoms, for the petals fall as a rule in one or two days, does not possess much value as a flowering shrub. But as an ornamental-fruited evergreen it is exceedingly attractive, and as it is particularly hardy it is expected that in places with a cold winter climate, such as New England or Eastern Canada, it may make an efficient substitute on walls for the Pyracanth so much employed in. this manner in Europe. ‘The form here figured was intro- duced about 1900 by Mr. E, H. Wilson for Messrs. Veitch & Sons, from whom the plant was purchased. In England
Fesrvary, 1912.
it can be grown as a shrub, and thrives well in loamy soil in a sunny situation. It can be increased either by cuttings or by seeds. SS. undulata, to which our form is here referred by Dr. Stapf, is taken in the sense proposed by Schneider, and includes S. Davidiana, Decne, which in turn appears identical with S. Henryi, Diels. The characters which dis- tinguish these Stranvaesias are somewhat slight. Though our numerous Chinese specimens can be assorted into two groups which approximately correspond to the S. undulata and S. Davidiana of Decaisne, these groups pass into each other. The plant figured is one of these intermediate forms, because its leaves are those of S. undulata as originally under- stood, while the inflorescences point to its being S. Davidiana. S. integrifolia, Stapf, from Kinabalu in Borneo, mainly differs from this Chinese species in having leaves with a smaller number of rather more prominent nerves.
Description.—Shrub or tree, reaching 30 ft. in height in Central China; twigs adpressed hairy; bark ultimately dark bluish-grey. Leaves lanceolate or oblanceolate, most variable on the same individual, acute or shortly sharply acuminate or even almost blunt, base wide or narrow acute, margin quite entire, 13-4 in. long, 2-11 im. across, coriaceous, green, paler and usually quite glabrous beneath, at first pubescent on the midrib and margins above, often marked as with silvery lines; nerves 7-12 on each side; petioles 5-8 lin. long, usually more or less hairy; stipules subulate, 3-5 lin. long, more or less persistent till flowering is past. Corymbs often leafy below, the larger 2 in. long and rather more across, dense or rather open, their rachises and pedicels more or less adpressed hairy, or occasionally almost glabrous ; pedicels ultimately elongating, 3 lin. long. Lfteceptacle hemispherical-turbinate, in flower 1 lin. deep, laxly and sparingly pubescent below, usually glabrous upwards, Sepals triangular, very short, minutely ciliolate. Petals white, orbicular, about 2 lin. across, soon falling. Stamens about 20, anthers red. Ovary tomentose above ; style about 2 lin. long; stigmas capitate. Fruit orange, somewhat depressed-globose, 3—4 lin. in diameter.

Nichollii, Dorrien-Smith in Gard. Chron. 1908, vol. xliii. p. 898.— W. B. Turrtn..
For the introduction of the interesting Leptospermum now figured Huropean gardens are indebted to Captain A. A. Dorrien-Smith, by whom it was brought to England from New Zealand in 1908. In the Gardeners’ Chronicle for that year Captain Dorrien-Smith informs us that in New Zealand this plant is termed L, Nichollii, a name previously unknown in this country. It is stated that the plant was first found growing on sandhills to the north of Christchurch, and is believed in New Zealand to have originated as a seedling from a white-flowered plant discovered some years earlier in South Island, known there as L. Chapmanii, another name previously unknown 1n English collections. It is further said that the flowers of plants raised from seeds of this L. Chapmanu vary from bright rose to white, while their foliage varies from green to the colour of the Jeaves of the Copper Beech, L. Nichollii being one of the forms in which the leaves are of this latter colour. So far as this character is concerned it is found at Kew that the foliage is copper-coloured only in plants grown in the open; those grown under glass.have the
Fesruary, 1912.
leaves green as shown in. our illustration. The information available suggests that both LZ. Chapmanii and L. Nichollii may be no more than seedling forms of L. scoparium, a some- what variable species widely distributed in Australia and New Zealand. In New Zealand botanical literature alone we find abundant testimony as to this variability; four distinguishabie forms are recognised in Mr, Cheeseman’s * Manual,” three of which were first described in Sir J. D. Hooker’s “ Handbook,” the fourth in Dr. Kirk’s “ Students’ Flora.” In this Magazine yet another variety, with pink flowers, has been described at t. 3419 as var. grandiflora; in the absence of more definite testimony it seems best for the moment to accord our plant similar treatment, as var. Nichollii, differing from the white-flowered type only in the brilliant carmine colour of the sepals, petals and filaments. Whatever its origin and status may be, L. scoparium, var. Nichollit, is a valuable addition to our gardens. It should command general favour since it is as hardy as L. scoparium itself, which is a common shrub in the open in the warmer parts of the United Kingdom and is hardy against a south wall at Kew. This variety is readily propagated from cuttings, and plants so raised flower when about a year old. The flowers open, in plants grown under glass, in April and last about six weeks.
Description.—Shrub reaching 10-18 ft. in height, much branched ; branches divaricate, at first silky, soon almost glabrous. Leaves alternate, lanceolate, 4 lin. long, 1 lin. across, mucronate, short petioled, rigid, faintly 3-nerved, punctate, green or copper-coloured, sparingly pubescent when young. Flowers solitary at the tips of rather short lateral twigs, about 2 in. across, feceptacle campanulate, glabrous, finely punctate. Sepals 5, ovate, obtuse, glabrous, coloured. Petals 5, spreading, carmine, Stamens about 30, I-seriate; filaments i lin. long, subulate, carmine; anthers very short, versatile, opening longitudinally. Ovary in- ferior, convex above, 5-lobed and 5-celled; style 1 lin.
long; stigma terminal capitate. Ovules many in each cell, linear, horizontal.

The handsome Qlearia which forms the subject of our illustration is confined to the Chatham Islands, east of New Zealand, where, according to Captain Dorrien-Smith, who has given an account of the plant in the passage quoted above, it grows in compact masses on the cliff edges or scattered about among the upland bogs in association with O. semidentata, Decne, a species which, according to Dorrien-Smith, is even finer than O. chathamica. In its native habitat the plant is in flower during the months from November till February, each plant blooming for a prolonged period. Both Mr. Cheeseman and Captain Dorrien-Smith state that the ray-florets may at times be white ; the disk-florets are violet-purple. The nearest ally of the species in the genus Olearia is O. operina,
Fesrvuary, 1912.
Hook. f., a native of New Zealand, from which our plant may be most readily distinguished by its broader leaves, and by its longér peduncles with fewer and more leafy bracts. For the material on which our figure is based we are indebted to the kindness of the Rev. A. IT. Boscawen, in whose garden at Ludgvan Rectory, near Marazion, a plant imported by Captain Dorrien-Smnith in 1908 flowered in June, 1911. The species, Mr. Boscawen informs us, has so far proved quite hardy at Ludgvan. It prefers a position sheltered from the mid-day sun, and seems to thrive best in a mixture of bog-earth, leaf-mould and grit. It is easily propagated by means of cuttings, which readily strike in the open without any protection.
Descriprion.— Shrub, 3-7 ft. high; stems stout, branches stout, sulcate, softly white-tomentose. Leaves alternate, oblanceolate or oblong-lanceolate, subacute or shortly. acuminate, narrowed below to a short broad _ petiole, 25-5 in. long, 3-14 in. wide, thick, firmly leathery, serrate with blunt thickened teeth, glabrous, reticulate and green above, densely white-woolly beneath, main nerves 2-3 on each side of the midrib and like it impressed above, slightly raised beneath. Heads peduncled, 2-2} in. wide; peduncle woolly with a few leafy bracts. Bracts of the involucre linear or oblanceolate-linear, acute or sub- acute, 4-5 lin. long, scarious, woolly towards the apex outside, glabrous within. Ray-florets many, usually pale violet-purple, occasionally in wild plants white; corolla- tube 2 lin. long, sparingly puberulous, limb oblong-linear, subacute, 7-8 lin. long, about 2 lin. wide, entire, elabrous. Disk-florets violet-purple ; corolla-tube cylindric, dilated upwards, 2 lin. long; lobes lanceolate, subacute. Anthers 1 lin. long. Style glabrous ; its arms subacute, under 1 Jin. long. uit narrowed to the base, suleate, 24 lin. long,
puberulous. Pappus I-seriate, setose ; setae unequal, the longest 2 lin. long.

The somewhat peculiar Crassula here figured was origin- ally discovered in Little Namaqualand by the late Sir Henry Barkly, who communicated it to Kew in 1875. The plants here figured were received at Kew from Professor H. H. W. Pearson, of Cape Town, in January, 1911; they formed part of a collection made during the Percy Sladen Expedition, and were found by Mr. Pillans, a member of the party, on a ridge four miles to the south-east of Bakhuis. Grown in a house devoted to succulent plants, these specimens flowered in March, 1911. While under these conditions the flowers produced have been white, there is reason to think that when fully exposed to sun and air in their native habitat the petals assume a reddish tinge. The stems too, as compared with those of the specimens collected by Barkly, are unusually long ; the original ones are only 1-14 inches high. Like other species of Crassula with a compact pyramidal habit, C. Barklyi is of slow growth and is prone, after flowering, to lose its vigour. The requirements of this and its nearer allies are best met Frsrvary, 1912.
by supplying dry tropical conditions and a sandy soil. Of these allies the most nearly related appears to be C. colum- naris, Linn. f., from which, however, C. Barklyi is readily distinguished by the characters mentioned by Mr. Brown.

The Brunfelsia which forms the subject of our illustration was first introduced to this country from Jamaica about a century ago, but the plant which supplied the material for the present figure is one obtained in 1904 for the Kew collection from Messrs. J. Veitch & Sons. This plant flowered at Kew in October, 1909. It is a vigorous shrub of upright habit and, as the plate shows, bore numerous flowers in the axils of the uppermost leaves so as to form large clusters at the ends of the branches, In wild speci- mens, however, it is usual to find but one terminal flower. This species belongs to that section of the genus wherein the corolla tube is many times longer than the calyx. Within this section the various species are difficult to discriminate. In one of them, B. nitida, Benth., the calyx is divided nearly to the base; this character is also exhibited by the plant which was figured in the Botanical Register, at t. 167, under the erroneous name B. undulata. In
B. americana, Sw., however, and in the true B. undulata, Marcu, 1919,
Sw., which is here depicted, the calyx is cup-shaped and has very short obtuse lobes, While, however, the two are closely allied, B. americana can be readily recognised by its obtuse leaves, whereas those of our plant taper to both ends. It is a matter for observation as to whether the colour of the corolla varies in this Species, because in Loddiges’ Botanical Cabinet, at t. 388, and in Reichenbach’s Flora Exotica, at t. 294, are given figures, under the name B. undulata, of a plant with a yellowish corolla. Under cultivation B, undulata thrives in a warm house when planted in loamy soil and liberally watered. It ought to prove a useful shrub in tropical gardens, for it appears to thrive in the open even in the south of Kurope, and plants have been raised at Kew from seeds which ripened in 1888 in the Botanic Garden at Palermo, There is reason to believe that it is represented in various private collections in this country, sometimes under the erroneous name of Portlandia grandiflora, Linn., also a West Indian plant which is, how- ever, readily distinguished, without taking into account other characters, by the fact that its leaves are opposite.
Desorrprion.— Shrub, or, in a wild state, a small tree reaching 20 ft. in height, with a comparatively slender stem. Leaves ovate-lanceolate, narrowed to both ends, subacute, quite entire, 24-7 in. long, 4-1? in. wide, glabrous; nerves slender, closely reticulate ; petiole 4 in. long. Flowers usually in wild plants solitary, terminal ; often in cultivated plants several in the upper axils forming terminal clusters ; peduncles very short. Calyx # in. long, shortly irregularly lobed, glandular pubescent externally ; lobes obtuse. Corolla white or apparently at times yellowish ; tube cylindric, slightly curved, 3-33 in. long, } in. in diameter, pubescent externally; limb spreading, 24 in. across; lobes 5, rounded, 1 in. wide, their margins undulate. Stamens as long as the corolla-tube. Ovary oblong, half as long as the calyx ; style cylindric, slightly exserted; stigma 2-lobed. Fruit sub- drupaceous. 2

The interesting Lilac here figured is a Chinese species nearly allied to the well-known Syringa pubescens, Turez., a
two together form the group recognised by Dr. Schneider as the Pubescentes, which belongs to the section Vulgares
as S. vulgaris, Linn., S. oblata, Lindl., S. persica, Linn., and 8S. chinensis, Willd. The species now described by Dr. Schneider as S. Judianae is one that was raised by Messrs. J. Veitch & Sons in the nursery at Coombe Wood from seeds sent from Western China by Mr. E. H. Wilson in 1901. The plant which supplied the material for our plate was obtained from Messrs. Veitch in 1909 under the name S. villosa.
Wing to the too curtailed descri ption of S. villosa originally provided by Vahl there has been some dubiety as to the identity of his plant. An examination of his type specimen
as, however, established the fact that the plant figured at t. 8292 of this work as S. Bretschneideri, Lemoine, is really
S. villosa, Vahl, and that the Lilac figured at t. 7064 under Marcu, 1919, 3
S. villosa is really S. pubescens, Turcz., the nearest ally of our plant. S. Julianae is, however, very distinct from S. pubescens in its villous leaves, branchlets and inflo- rescence ; S. velutina, Komarov, which also resembles our plant, is readily distinguished by its different calyx. S. Julianae as grown at Kew is at present a small shrub 3 to 4 feet in height, bushy and virgately branched ; it promises to attain a considerably larger size. It flowers in late May and in June, and although it is not likely to become a rival in gardens of the fine Lilacs now in cultiva- tion, it is worth a place as a pretty and unusual type of the genus Syringa. The blossoms have the characteristic fragrance of the Common Lilac, but are strikingly distinct from those of other cultivated species in the deep purplish lilac colour of the corolla-tube outside as contrasted with the nearly white corolla-segments inside, and in the purple peduncle and pedicels. The glabrous calyx is purplish- violet. The species should be grown in rich, moist, loamy soil, and can be propagated by cuttings of moderately firm young wood placed in gentle heat in July.
Descriprion.— Shrub, 3-4 ft. high or higher, shortly and densely branched, twigs of the present and of last season’s growth rather pubescent, at length becoming glabrous and blackish. Leaves ovate-elliptic, acute and cuneate, quite entire, ‘green, shortly pubescent, beneath rather pale and rather markedly pubescent especially on the nerves, 1-1# in. long, 1-1 in. wide; petioles under + in. long, puberulous. Inflorescences terminal, cymose, small, rather more than 2 in. in length, branches and pedicels very short, slightly hairy. Flowers white and lilac-purple, 3-4 lin. long; bracts linear, shorter than the calyx, caducous. Calyzx violet, glabrous; teeth rather distinct, wide-triangular, acute. Anthers violet, inserted a little below the corolla-throat. Fruit not known ripe, when young not verrucose.

. The interesting Dombeya here figured was raised at Kew
from seed received in 1907 from Mr. J. M. Wood, the
veteran Director of the Botanic Gardens at Durban, where
it had been in cultivation under the name of D. spectabilis,
Boj. When it flowered for the first time in February, 1911,
it was found on examination that it is not Bojer’s plant so Marcu, 1912.
named, but that it is the species described for the first time in 1900 by the late Dr. K. Schumann as D. Calantha and based by its author on herbarium specimens received at Kew in 1897 from Zomba in British Central Africa, where the plant had been collected by the late Mr. A. Whyte and by Mr. J. M. McClounie. The examination of flowers of this cultivated specimen, and a re-examination of those of the original type, have shown that the number of ovules in a cell is usually 6-8, not 4-6 as Dr. Schumann was led to believe. This point, though apparently not important, deserves to be noted, owing to the fact that in this genus some stress has been laid by Dr. Schumann on the number of ovules present in each cell. Another character which Dr. Schu- mann has treated as of consequence is the presence or absence of stellate hairs within the ovary; it is to be noted that in the species now figured these stellate hairs occur, but that while present on the inner wall they are absent from the septa. The material from which our figure has been prepared was derived from a plant which has grown vigorously in a border in the Mexican house in Kew, and which, but for severe annual pruning, would have attained tree-like dimensions. It is an evergreen, and when loaded with flowers, which are of the same tint as, and bear a strong superficial resemblance to those of the Musk Mallow, is a singularly attractive object. Unfortunately at Kew it has failed to ripen seeds,

The Corokia here figured, C. Cotoneaster, is a native of New Zealand, where it is found both in the North and in the South Islands, A familiar plant in gardens, especially in the south and west of England and in Ireland, it is scarcely hardy in the open ground at Kew; it will survive a mild winter, but is injured or killed by a few severe frosts. On a south wall, however, it thrives excellently and flowers freely every May. ‘The material from which our figure has been prepared was obtained from a plant grown by Canon Ellacombe at Bitton, near Bristol, which forms a bush in a sheltered corner of his remarkable garden, but otherwise is not protected. This specimen is now a shapely plant five or six feet high and shows the remarkably interlaced branches with their tiny leaves and bright yellow, starry
flowers to excellent advantage. C. Cotoneaster will grow Marcu, 1912,
either in loamy or in peaty soil provided it be open and well drained, ard can be increased by cuttings of firm twigs taken off in July and placed in gentle heat. Raoul and others describe the ovary as 2-celled with one ovule in each cell; De Wildeman has figured the ovary as 1-celled and directed attention to the fact that this is the usual arrange- ment. In all the flowers examined by Mr. Hutchinson only one loculus containing a single pendulous ovule has been found, his experience thus coinciding with that of De Wildeman, not with that of Raoul.

The very beautiful Cereus which forms the subject of our plate is a native of Argentina, where it was originally discovered in the provinces of Tucuman and Salta by Dr. Philipp Silvester, in whose honour it was named. A member of the group of forms to which belongs C. procum- bens, Kngelm., figured at t. 7205 of this work, it is readily distinguished from that species by its more slender stems, its more closely approximate cushions of spines, the spines themselves being smaller; it differs also in having smaller flowers which are very unlike those of C. pubescens in colour. The plant which supplied the material for our illustration was purchased in the spring of 1911 for the Kew collection from Messrs. Haage & Schmidt, of Erfurt. In the catalogue of this firm a figure of the plant is given; that figure represents it as a compact many-stemmed herb of semi- dependent habit growing in a hanging pot. At Kew it flowered freely in May, 1911, in the house devoted to succulent plants, The elegance and the bright orange- scarlet colour of its flowers, exceptional in the genus, fully
Maron, 1912,
entitle it to horticultural favour. The cultural require- ments of C. Silvestrii are a loamy soil and abundant sun- shine; a fair allowance of water should be supplied in summer, with little or none at all in winter.
Descriprion.—/erb; stems succulent, prostrate or the central ascending, 14-4 in. long, 4-7 lin. thick, 8-angled, pale-green ; spine-cushions very closely set; spines 16-20 to a cushion, setaceous, 1 lin. long or shorter, white. Flowers showy, lateral, erect, infundibuliform; tube 1-1 in. long, straight, 4-5 lin. wide at the top, reddish, loosely clothed with very small, ovate acute, pilose scales ; segments 3—4-seriate, spreading, 4-2 in. long, 2 lin. wide, lanceolate, acute, brilliant orange scarlet.

The Schomburgkia which forms the subject of our illustration is an Orchid which is interesting as having reappeared after having been lost sight of for half a century. The species was first described by Mr. E. Prillieux in 1862 from a specimen in the collection of Mr. Liiddeman in Paris,-but nothing was then known of its native country or of its history, though its affinity with S. undulata, Lindl., was pointed out and especial attention was drawn to the bright yellow patch on the lip which is a conspicuous feature of the plant. In January, 1908, an auction sale of surplus orchids from the collection of the Hon. W. Rothschild, Tring Park, was held in London. At this sale the plant from which our figure has been prepared was purchased for the Kew
ApriL, 1912.
collection. Its identity was unknown, but the plant was reported to have been received originally from Venezuela. This plant has been grown in a teak basket in a mixture of peat and sphagnum in a warm house along with S. undulata and other species of the genus, and has thriven well under this treatment. It was not, however, until. January, 1911, that the plant flowered for the first time at Kew. When it did flower it was found to possess all the features characteristic of the species which Prillieux had named S. Lueddemani. Like other Schomburgkias the plant requires a liberal allowance of direct sunshine, and after a season’s growth is completed should be kept, for a few weeks, dry at the roots.
Descriprion.—Herb, epiphytic; rhizome stout, clothed with broad, ovate, somewhat imbricate sheaths ; pseudobulbs erect, fusiformly clavate, sulcate, narrowed to the base, clothed with distichous imbricate sheaths, 6-10 in, long, 1-14 in. thick about the middle, often 2-leaved at the tip.

Although the Magnolia here figured is less effective than some other members of the genus so far as its flowers are concerned, it is at least in one of its forms one of the most striking. If, for the genus, the flowers be small, the tree which bears them is, according to Professor Sargent, in the neighbourhood of Sapporo in Japan, one that attains a height of over 70 feet with a straight clean trunk 6 feet in girth. In stature therefore it rivals M. hypoleuca, Sieb. and Zuce., another native of Japan figured at t. 8077 of this work, and M. acuminata, Linn., f., from the eastern United States. The nearest allies of M. Kobus are, how- over, M. stellata, Maxim., figured at t. 6370 of this work, which is always a small shrub and which has from twelve
Aprin, 1912.
to twenty petals to a flower, and M. salicifolia, Maxim., which has glabrous peduncles and winter-buds with narrower leaves that are glaucous beneath. But besides the lofty form alluded to, which Sargent has treated as a distinct variety, var. borealis, there is another form of M. Kobus, also represented in European collections, which while it never attains the dimensions of the Sapporo tree, differs from its companion in flowering more freely while still young and in having smaller leaves and more slender twigs. This second form, the one on which the original description of the species was based, is that to which the plant whence our material was derived belongs. That form was’ first introduced to England about 1879 by Mr. ©. Maries when collecting for Messrs. J. Veitch and Sons; the original tree is still in their nursery at Coombe Wood. ‘The trees at Kew, which are now about 15 feet high, usually come into leaf early in April. The spray figured, which came from one of these, did not flower until May, 1911, the flowers of this Magnolia, like those of most early flowering trees and shrubs, having been retarded for three or four weeks by a long-continued cold spell. This circumstance also explains the forwardness of the foliage as depicted in our plate; as a rule the flowers appear on quite naked shoots. In gardens M. Kobus will be valued for its great hardiness, its shapely pyramidal form and its copious leafage. As a flowering tree it is also highly attractive, and in this respect it suffers from comparison only with other members of the same genus, which includes some of the finest flowering trees of the northern temperate zone. It likes a moist, deep, open soil and should be raised from imported seeds.
Description.— Tree, deciduous, of narrow pyramidal form when young, ultimately rounded, in one form 15-20 ft., in another 70-80 ft. in height; twigs aromatic when bruised, dark brown and silky about the nodes when young; almost black when a year old; winter-buds pubescent. Leaves obovate, cuneate at the base, bluntly cuspidate at the tip, entire, 4—7 in. long, 2-4 in. wide, glabrous or glabrescent, conspicuously reticulately veined beneath; petioles 3-1 in. long. Flowers 4 in. across, solitary at the tips of short lateral twigs, Sepals 3, subulate, caducous, 3 in. long, greenish, glabrous. Petals 6, pure white with a purple

The subject of our illustration is one of those Agaveae which differ both from the true Agaves and from the Littaeas in having the flowers solitary on simple racemes or spikes and in having herbaceous leaves without a terminal pungent spine. Considerable diversity of opimion has existed with regard to the status of the group which about a century ago appeared to Salisbury entitled to generic recognition, though the name Manfreda, a Sap by him for Agave virginica, Linn., figured at t. 1157 o this work, was not published until 1866. Thirty years later H. Ross treated the group as a distinct genus Leicht- linia, a name bestowed upon the species now figured because of its introduction by the late Mr. Max Leichtlin. But the structure of the flowers in all species of Manfreda, which
Aprin, 1912.
name takes precedence of Leichtlinia, agrees so well with that of the Agaves and the Littaeas that it seems desirable to consider the group a subgenus of Agave. All the Man- fredas are Mexican with the exception of A. virginica which is confined to the Southern United States. One of the best known is A. maculata, Regel, figured at t. 5122 of this work as “A. maculosa.” The Kew plant of A. protuberans was received from Mr. Leichtlin in 1882 shortly after its introduction from Mexico, where it in- habits the mountains near San Luis Potosi at altitudes of 6,000-8,000 feet above sea level. The species flowered in 1908 with Mr. R. H. Beamish at Glounthaune near Cork, and in June, 1910, at Colesborne, with Mr. H. J. Elwes, to whom we are indebted for the material for our figure. Like the other Manfredas, A. protuberans requires green- house conditions,

The interesting Daphne here figured was first discovered by Mr. A. E. Pratt in 1889 at altitudes of between 9,000 and 13,000 feet in the neighbourhood of Tatien-lu in Western Szechuan. In 1903 it was again collected in the same district by Mr. E. H. Wilson, and was sent by him to Messrs. J. Veitch and Sons who have raised it in their nursery at Coombe Wood. ‘The material on which our illustration has been based came from a plant in the Coombe Wood nursery, where it is an evergreen shrub of compact and shapely form, about eighteen inches high and as much wide, well furnished with shining dark green foliage. The flowers, which are freely produced in early May along with the new leaves, have all the pleasing fragrance that is characteristic of the genus, which, taken as a whole, is not very easy to cultivate. Judging, how-
AprIL, 1912,
ever, by the appearance of the plants at Coombe Wood, D. retusa promises to be more amenable to treatment than most. It will probably have to be propagated by grafting, and an evergreen species like the familiar D. Laureola should be tried as a stock, although it may be possible to work it on the deciduous D. Mezereon as well. D. retusa approaches very closely to D. tangutica, Maxim., a species described from specimens collected in Western Kansu, and differs from the Kansu plant, if the only specimen of the latter at Kew can be relied upon, mainly in having more hairy young branches, broader and less revolute leaves, more densely ciliate perulae and more obtuse perianth segments,

The very interesting Campanula here figured is a species which is endemic in Northern Spain, where it is confined to that portion of the Cantabrian mountains known as the Picos di Europa which lies between the provinces of Leon and Asturias. It was first recognised as a distinct species under the name C. arvatica more than a century ago, but appears to have been lost sight of until some thirty years ago when it was rediscovered and again described by Leresche and Levier as C. acutangula. Its nearest ally in the genus is C. Morettiana, Reichb., a native of the Tirol, and occasionally in gardens it is treated as a variety of that species. The Spanish is, however, very readily distinguished from the Tirolese plant in being glabrous in all its parts, in having smaller leaves, more slender stems, and especially in having a more open and less distinctly funnel-shaped

corolla, Though the names C. acutangula or C. Morettiana var. acutangula appear to have become generally adopted in collections, Feer has made it perfectly clear that they are only recent substitutes for the original name and must therefore be set aside. The plant from which the material for our figure was obtained is one purchased for the Kew collection in 1909 from Mr. H. Correvon, of Geneva, under the name proposed by Leresche and Levier. It forms a close prostrate tuft about 2 inches high and should be planted in a sheltered position in well-drained shingly soil. The flowers are produced in July ; unfortunately the species has not proved hardy at Kew.
_ Descriprion.—Herb, perennial; rootstock central, giving out numerous stems in all directions. Stems slender, slightly angular, glabrous, leafy, one- or more-flowered, 4-8 in. long. Leaves dimorphic; basal about 1 in. long, slightly broader than long, cordate-rounded, with petioles $-% in. long; cauline alternate, 3-4 lin. long, 2-3 lin. wide, rhomboid, shortly petioled or the uppermost. sessile ; all apiculate, sharply toothed, glabrous, with 5 obscure main- nerves. lowers solitary, or both terminal and axillary at the ends of the stems and branches.

Davidia was one of the earliest and is certainly one of the most striking of the novelties discovered in Western China when the botanical exploration of that region was begun over forty years ago. The first specimens were transmitted to the late Professor Baillon by the Abbé
May, 1912.
David in 1869; the first to reach Kew were collected by Mr. A. Henry in 1889. Horticulture owes the introduction of the genus into cultivation to Pere Farges, who sent seeds, from which a solitary plant was raised, to Messrs. Vilmorin in 1897. Farges sent a second supply of seeds in 1898, and in 1899 Mr. E. H. Wilson sent to Messrs. J. Veitch & Sons a third consignment, from which a large stock of plants was obtained. The original tree raised in 1897 flowered for the first time in the collection of Mr. M. L. de Vilmorin at Les Barres in 1906 and was figured in the Gardeners’ Chronicle that year on 2nd June at p. 346. The trees in the nursery of Messrs. Veitch at Coombe Wood flowered for the first time in 1911, and a figure was given in the Gardeners’ Chronicle that year on 27th May at p. 329. Both of these figures represent conditions with relatively smal] flowers. Meanwhile, however, the original tree at Les Barres has at last developed its full beauty, and from this tree has been obtained the material on which our illustration has been based, the fruiting specimens having been supplied by Mr. M. L, de Vilmorin in October, 1908, the flowering sprays in May, 1911. Mr. Hemsley has discussed the history of the introduction of Davidia in the Kew Bulletin for 1907 at p. 301, and described the germination of the seeds in the Linnean Society’s Journal, vol. xxxv, at p. 556, while Mr. A. S. Horne has dealt exhaustively with the structure and affinities of this remarkable plant in the Linnean Society’s Transactions, series 2, vol. vii. at p. 303. The various forms which it assumes are considered by Mr. Hemsley, Mr. M. L. de Vilmorin,; and Mr. E. H. Wilson to be no more than varieties of one species. Mr. L. R. Dode, however, is inclined to distinguish three species, recognisable by the colour and the degree of pubescence of their leaves. Asa tree for the climate of the British Isles Davidia possesses two very valuable characteristics: it starts into growth late and finishes early. Thus it escapes damage alike from late spring or from early autumn frosts. So far as the experience of the last ten years enables us to judge it Is quite hardy. A vigorous feeder, it needs a deep, moist, well-drained loam. It can be increased by cuttings, but
plants so raised do not grow with the clean vigour of seedlings.
Descriprion.— Tree of medium height, with Linden-like foliage, and capitate inflorescences with two large white bracts. Leaves alternate, ovate- or orbicular-cordate, abruptly caudate-acuminate, coarsely serrate with glandu- lar or thickened teeth, 24-44 in. long, 2-3 in. wide, at first adpressed hirsute, especially on the midrib and
hherves, soon glabrous; main-nerves 5-7 on each side,
rather prominent, forked; petiole slender, 13-4 in. long, almost cylindric, with a faint channel above; stipules 0. Inflorescence apparently terminal, capitate, pendulous, monogamous or heterogamous; peduncle 2-bracteate near the top, in flower 2-3 in., in fruit 3-4 in. long; bracts almost opposite, sessile, usually unequal, leafy, white, membranous, oblong-lanceolate or oblanceolate, acuminate, base rounded or subcordate, the longer up to 6 in. in length, overhanging the pendulous capitulum, soon de- ciduous. Capitulum generally heterogamous, about 14 in. across, many-flowered, with a solitary 2-sexual and many male florets, or with only male flowers, or only a solitary female flower; receptacle subglobose, without bracteoles. Male flowers sessile, naked or with perianth reduced to a swollen ring. Stamens 1-7, or sometimes (Horne) 12, attached annularly; filaments well developed, filiform; anthers purple, cordate, 2-locular, apiculate. Hermaphro- dite (or apparently hermaphrodite) flower shortly pedicelled, obliquely set on the globose receptacle. Perianth 0, or reduced to minute epigynous scales mixed with the stamens. Stamens 5-10 or more—sometimes up to 26 (Horne); small, epigynous and usually apparently imperfect. Ovary inferior, generally 7-celled; cells 1-ovuled; style-lobes as many as cells, much recurved; ovules pendulous. /’ruit drupe-like, ellipsoid, about 13 in. long, greenish-yellow with brown dots; epicarp and mesocarp thin; endocarp bony, very hard, opening by dorsal chinks extending to the middle of the fruit; embryo straight, enclosed in a thin endosperm ; radicle superior, rather shorter than the oblong cotyledons.

The handsome Jris here figured was discovered in Western Szechuan in 1908, where it was found by Mr. EK. H. Wilson growing in thickets near Kuan Hsien at elevations of from 7,000 to 11,000 feet above sea-level. The plant from which the material for our plate was obtained was grown by Mr. W. R. Dykes in his garden at Charterhouse, Godalming, from a seedling raised by Miss Willmott in her garden at Warley Place, Essex. It came into flower towards the end of May, 1911. A freely floriferous species and at the same time one of the most richly coloured of those now in cultivation, . chrysographes promises to prove a favourite garden plant. As Mr. Dykes has pointed out in the Gardeners’ Chronicle, the species is a member of the “Sibirica” group, and is closely allied to I. Forrestii, Dykes, but differs in colour of flower and in habit; it also flowers somewhat earlier than J. Forrestii,
May, 1912.
Among the more familiar species in collections it also approaches rather closely to /, laevigata, Fisch., but may be at once distinguished by its narrower, more sharply pointed spathes. The rich dark purple flowers with their velvety texture render the plant a very conspicuous object ; the colour is well set off by the central line and. the broken flanking streaks of golden yellow. These flanking streaks vary somewhat in number and extent, sometimes they are almost absent and only the central golden yellow line appears. Another species closely allied to I. chryso- graphes is I. Delavayt, Micheli, from Yunnan, which has, however, a different capsule and seeds, and as a garden plant is readily distinguished by its taller stature and by its blue purple flowers with white markings. Mr, Dykes finds that J. chrysographes is not difficult to grow in any soil that is fairly rich in humus and is not heavily charged with lime. It appears not to demand either the excessive
moisture or the very retentive soil in which J. Delavayi best succeeds.
Description.—Herb ; rhizome rather slender, giving off several rather slender unbranched stems, hollow with a narrow lumen, about 14-14 ft. high, bearing 1-2 reduced leaves and 1-2 flowers. “Leaves linear, much narrowed upwards, acute, curving outwards, 1{-1} ft. long, 1-1 in. wide, green. Spathes narrow, green, acute, 2-24 in. long. Pedicels 1-1} in. long. Perianth with tube about 5 lin, long; outer segments much deflexed ; blade oblong- or almost obovate-elliptic, 2 in. long, 1 in. wide, brilliant dark purple-violet, velvety papillose, marked in the centre with golden yellow lines and streaks; claw linear-oblon , 1-1} in, long, reddish purple, finely dotted with golden yellow; inner segments erect, oblong, obtuse, narrowed below into a claw, altogether 24-21 in, long, 4-5 lin. wide, dark purple-violet.

The subject of our plate is an old garden plant which has been grown for many years in the collection at Kew, where it is quite hardy. Perhaps the finest of the Silver Saxifrages, S. lingulata was discovered by Bellardi in the mountains of Piedmont towards the close of the eighteenth century, and was at first confused by most botanists with the Pyrenaean S. longifolia. Typical S. lingulata would appear to be all but confined to the Italian Maritime Alps. On the French side of the frontier its place is taken by a distinct variety, var. lantoscana, Engl., which has_ short, spathulate, very obtuse Jeaves and a unilateral panicle. In Central and Southern Italy it is again replaced by another distinct variety, var. australis, Engl., which has broader, more or less linear-spathulate Jeaves. These two varieties have sometimes been treated as specifically distinct from S. lingulata proper, but the identity of the three as regards
May, 1912.
floral characters and the existence of numerous intermediate forms—apart altogether from possible hybrids—render it inadvisable to separate them specifically. It is interesting to note that the high-level forms of var. australis from Naples and Sicily approach more closely to var. lantoscana, at the other extreme of the general specific area, than they do to the typical plant. Though hardy at Kew, the atmo- spheric conditions are adverse to the formation of good Inflorescences in the open, and the plant shows to most advantage when given frame treatment and planted in a pot or pan of loam and powdered limestone. Away from the smoke of London, as for example in the garden of Miss Willmott, at Warley Place, Essex, this Species is a success, planted on a rockery in a sunny position, where it thrives
vigorously and forms a large clump. S. lingulata flowers in May.
Descriprion.— Herb, with a rosulate many-leaved crown and a central flowering stem. Leaves linear or sometimes subspathulate-linear, acute, 1-5 in, long, 14-23 lin. wide, rigid, recurved, channelled above, red near the base, with numerous marginal pits loaded with chalk. Panicle many- flowered, rather oblong; the flowering stem below the panicle 2—5 in. long, leafy ; bracts oblong, acute, the lower about } in. long, the rest gradually smaller upwards. Calyx finely glandular near the base; lobes suberect, oblong with rounded tips, over 1 lin. long, under 1 lin. wide, glandular-ciliolate. Petals narrow-obovate or oblong- obovate, 4 lin. long, under 2 lin. wide, white, ciliolate near the base and dotted with reddish-purple within, 3-nerved in the upper two-thirds. Filaments subulate, those opposite the sepals over 1 lin. long, rather longer than those opposite the petals. Styles short, free, ultimately recurved at the tip.

The Swan River Peach Myrtle, which we here figure, 1s a West Australian plant that half a century ago was a favourite decorative pot-shrub in English conservatories, where it was grown along with species of Boronia, Chori- zema, Epacris, and Erica. Now that the cultivation of hard-wooded greenhouse plants has fallen out of favour it is rarely seen in private collections. Out of doors it has always been somewhat difficult to grow, even in the most favoured parts of the United Kingdom, and the plant from which the material on which our plate is based was derived has the two-fold interest of being one which was grown in the open, though in a very sheltered position under a wall, in the garden of the late Mr, Gumbleton at Belgrove, Queenstown, and of being the last of the many contribu- tions sent by that distinguished and successful gardener to

embellish the pages of this Magazine. In the garden at Belgrove it flowers in the month of February. The plants, which are now included in the genus Hypocalymma, were at first considered to belong to the genus Leptospermum, though they were treated by Endlicher as constituting a distinct section of the latter genus. To this section Lindley and Schauer simultaneously and independently accorded the rank of a distinct genus, and their decision has never been questioned since, though, owing to a typographical error which has found currency, the name in English garden lists has of late years usually been given as Hypocalymna.
Drscription.—Undershrub, 3-4 ft. high; twigs strict, virgate, glabrous; bark reddish-brown. Leaves spreading, sessile, thick, linear or linear-lanceolate, acute, 4-3 in. long, more or less triangular in section, sparingly glandular. flowers axillary, usually in pairs, sessile; sometimes 3—4- nate and then borne on a very short rather stout peduncle; bracts and bracteoles scarious, about 1 lin. long, nearly as wide, concave.

The pleasing Calceolaria here figured was presented to Kew in 1909 by Messrs. F. Sander & Sons, St. Albans, to whom seeds had been sent by Mr. Forget when collecting on their behalf in Peru. It forms a compact little shrub, and when out of flower has the aspect of a Heliotrope or of a bedding Verbena. When it flowered for the first time it was believed to be C. virgata, Ruiz & Pav., to which it is certainly closely allied, and under this name was referred to in the Gardeners’ Chronicle, 1912, vol. li. p. 50, where a figure, reproduced from a photograph, is given. But, as Mr. Skan points out, the figure originally supplied by Ruiz and Pavon of their C. virgata (Fl. Peruv. vol. i. t. 31,
May, 1912, a
fi. a) represents a plant with opposite or ternate subsessile leaves, and with a considerably diverse lip. No doubt the species now figured has been, in various collections, referred to C. virgata. The flowers of C. Forgetii are smaller than is usual in the genus and are not very. conspicuous in colour; they are, however, very freely produced, and on this account impart a distinct horticultural value to the plant. They are remarkable from the fact that the pouched lower lip points upwards. At Kew plants placed in an open sunny border have grown well and flowered freely in summer, but have not withstood the winter in the open. Plants grown in pots in a greenhouse have, however, flowered almost as freely and proved equally attractive.
Descriprion.— Undershrub, 1-1} ft. high; stems slender, terete, grey pubescent with purplish bark; internodes 1-24 in. long. Leaves ovate, 4-21 in., usually 14-13 in. long, 3-14 in, usually 3-1 in. wide, obtuse or subacute, irregu- larly crenate serrate, base rounded or somewhat cuneate, dark green and shortly pubescent above, paler beneath and nearly glabrous, but beset with sessile glands except along the pubescent nerves and veins ; petiole 4-4 in. long, rather closely hairy. Cymes at the ends of the stem and branches, forming an oblong or pyramidal lax many- flowered panicle 6-8 in. long. Pedicels slender, 4-4 in. long, shortly but rather closely pubescent. Calyx about 2 lin. long, 4-lobed; lobes wide-ovate or suborbicular, subequal, 15-2 lin. long, 1-14 lin. wide, obtuse or rounded, quite entire, densely hairy or villous outside and on the margins, beset with sessile glands.

The Flame Tree, for such is the name given in Queens- land and New South Wales to the. species which forms the subject of our plate, is a tree which attains, in its native forests, a height of from sixty to a hundred and twenty feet, with a trunk three feet through; it yields a soft light- coloured wood. According to Loudon the species was first introduced into England in 1824, and there is a drawing in the collection at Kew made from a plant growing in the Royal Gardens in 1826. This drawing bears a note to the effect that the plant was introduced from New South Wales in 1825. In the garden of Lady Hanbury at La Mortola, Ventimiglia, B. acerifolius thrives in the open ait, but at Kew it can only be grown under glass, and the material for our illustration has been obtained from a plant which is

grown in one of the beds in the central portion of the Temperate House, and is now a tree about forty feet high. This plant has been in cultivation at Kew since 1862, when it was presented to the national collection by Messrs. J. Veitch & Sons, Chelsea. Under cultivation in a greenhouse the species is easily kept in health, but it evidently requires abundant sunshine to induce it to flower, which the Kew plant did for the first time in June 1910, Already two other species of this genus have been figured in this work ;

The interesting Epacrid which forms the subject of our plate was discovered by Messrs. J. H. Maiden and W. Forsyth near the southern edge of the King’s Tableland in the Blue Mountains of New South Wales in 1898, and was first described by Mr. Maiden in the same year. To Mr. Maiden horticulture is further indebted for its introduction to this country, and the plant from which the material for our figure was obtained is one raised from seed sent by him to Kew in 1906. The structure of the anthers appeared to Mr. Maiden, when first describing the plant, to render its position among the Kpacrideae somewhat obscure, but on account of the general agreement of the species with the genus Epacris itself as regards foliage, Mr. Maiden placed Rupicola next to Epacris. In this, as it now appears, the author was fully justified, since Rupicola is found to agree with Epacris as regards its anthers. With the species of Epacris, Rupicola further agrees in the matter of cultural requirements, and when treated as they are treated it forms

HurcHrnson,
The beautiful Zora here figured is one that has been in cultivation at Kew for at least a couple of decades. It was originally received from the Royal Botanic Garden, Pera- deniya, Ceylon, under the garden name J. coccinea, var. lutea, and under this name it is now to be met with in many private collections and in various nursery catalogues. It is certainly, as this garden name implies, most nearly allied to 1. coccinea, figured long ago at t. 169 of this work. But it is readily distinguished from J. coccinea, not only by the colour of its flowers, but by its more Jax inflorescence and by the larger ovate-rhomboid corolla lobes, though in habit and foliage it bears a close general resemblance to the
various named forms of J. coccinea in cultivation. Like these dons, 1912,
other garden Ixoras, J. lutea is easily cultivated under moist tropical conditions, and like them, when in flower, is an exceedingly attractive plant.
Descriprion.—Shrub, 2-3 ft. high, erect; young twigs at first finely puberulous, at length glabrous. Leaves oblong-elliptic, distinctly mucronate, base somewhat un- equally cordate, 3-34 in. long, 12-2 in. wide, thinly papery, margin slightly recurved, pale green, glabrous on both sur- faces, lateral nerves about 10 on each side of the midrib, spreading, looping within the margin, raised beneath, secondary venation lax, distinct both above and below; petiole stout, 7-8 lin. long, finely puberulous; stipules long subulate from a wide base, 4-5 lin. long, about 24 lin. wide at the base, glabrous. Corymbs lax-flowered, about 23 in. across; main branches up to # in. long, finely puberulous; bracts triangular-subulate, acute, about 1 lin. long. Flowers pale yellow, sessile. eceptacle under 1 lin. long, puberulous. Calya 4-lobed ; lobes wide ovate, subacute, under 1 lin. long, nearly as wide, coriaceous, their margins membranous and at times sparingly toothed, finely puberulous outside, pecti- nately glandular at the base within. Corolla 4-lobed; tube cylindric, 14 in. long, very slender, glabrous outside; limb about 1 in. across; lobes ovate-rhomboid, mucronulate, 6-8 lin, long, 2$—-4 lin. wide, glabrous. Anthers almost sessile, exserted, 2 lin. long, acutely acuminate. Ovary 2-celled ; style slender, glabrous, shortly exserted, its arms 1 lin. long, slightly recurved and flattened on the inner face.

The Lycium which forms the subject of our illustration is the most distinct and, as a flowering shrub, the most effective species of the genus in cultivation. It was first discovered by Fremont in 1844 on the Rio Virgen, one of the tributaries of the Colorado River, where it forms a small bush 2-3 feet in height. There are, as Dr. Asa Gray has pointed out, two distinguishable forms of L. pallidum 3 one of these, which is the form figured by Miers, was collected by Fendler in New Mexico, and has the corolla-tube quite glabrous inside; the other, from Colorado, which is that now figured, while agreeing with the New Mexican form in all other respects, has the corolla-tube hairy inside below the insertion of the stamens. his form, which has been in cultivation in the open at Kew since 1886, blossoms freely every year from the end cf May until mid-June, its slender spreading branches being gracefully wreathed from base to tip with pendent, pale-greenish, purple-tinged flowers. But
June, 1912,
until 1911 not one of the examples in the Kew collection ever developed a fruit; in that summer, doubtless owing to the prolonged and excessive heat, an abundant crop of berries was produced. ‘These, being of a bright red colour, rendered the plants most attractive during July and August. Hitherto the species has been propagated by layering, cuttings having proved difficult to strike. Doubtless this method of increase will still, as a rule, require to be adopted; it may be long ere another crop of fruits is borne. A loamy, well- drained soil, of a light rather than heavy yet by no means too light character, suits it best, and it must be given the sunniest position available.
Descriprion.— Shrub, 3-4 ft. high, much branched; branches spreading, brownish, densely leafy, armed with straight spmes. Leaves clustered on the thickened nodes, oblanceolate, obtuse, narrowed to a short petiole, 1-1} in. long, 4 in. wide, glaucous, somewhat fleshy, obscurely veined. Flowers solitary or in pairs; pedicels 2 lin. long, glabrous. Calyx rather shorter than the pedicel, cup- shaped, fleshy, glabrous; lobes 5, as long as the tube, obtuse or somewhat acute.

The Labiate genus Perovskia, to which the plant here & figured belongs, is a somewhat anomalous one, comprising
four species, two of which are natives of Turkestan with a ; third confined to Beluchistan, and a fourth, the one now ; depicted, which extends from the mountains of Afghanistan through the Western Himalaya to Western Tibet. In the Karakoram Range it is met with at elevations up to 10,000 feet above sea level. Dr. Aitchison has reported it as plentiful in certain parts of the Kuram Valley, and described it as being singularly striking when in flower. The flowers in Afghanistan are usually lavender-coloured,
Jung, 1912,
but are occasionally pure white ; the plant has an odour closely resembling that ‘of Salvia officinalis. The plant from which the material for our plate has been obtained is one that was procured for the Kew collection in 1906 from Messrs. Bees, Limited. Under cultivation it retains the features attributed to it in the wild state by Aitchison; its chief value as a garden plant lies in the abundant and very pleasing display of blossom which it provides in August and September when few shrubby species are to be had in flower. The silvery grey of the stems and flower-stalks affords an admirable contrast with the rich violet-blue of the corollas. The flowers are produced ina large panicle, 1-1} ft. high, terminating the current season’s growth. Much of the upper part of this growth is soft and dies off in winter; the plant should therefore be pruned back to the woody portion of the stem and branches every spring. Like most of the Labiate family, it is easily increased by cuttings cf young wood, made about July and placed in gentle heat. P. atriplicifolia thrives well in ‘a deep but not heavy loam. There has been some dubiety as to the exact natural position of the genus, mainly perhaps owing to the fact that both Karelin and Bentham ‘have described as the upper lips of the calyx and corolla what in reality are the lower. Bunge, who pointed out this misapprehension in 1851, has shown that the corolla is almost identical in structure with that of some of the Ocimoideae. The flowers are dimorphic ; some- times, as in our figure, with short stamens and an exserted
style, sometimes with an included style and with exserted fertile stamens.
Description.— Shrub, 3-5 ft. high. Stem erect, strict, terete, shortly stellate-tomentose hoary, branching upwards. Leaves ovate-lanceolate or lanceolate, the largest 14-21 in. long, 3-1 in. wide, subacute, irregularly serrate or incised, gradually narrowed to the base, ‘at first more or less covered with simple or stellate hairs, at length nearly glabrous, resinously glandular on both surfaces with rather raised main-nerves beneath ; petiole 4-3 in. long. Inflores- cence paniculate, 1-14 ft. long, with numerous strict, slender, spiciform branches; whorls very numerous, 2—6-flowered, more or less segregated; bracteoles narrow-ovate or lanceo- late, shorter than the calyx. Flowers sessile or very shortly
pedicelled. Calyx tubular, 14-2 lin. long, slightly 2-lipped, densely white tomentose, resinously glandular; upper lip unequally 3-toothed, lower 2-toothed; teeth deltoid, acute, very short. Corolla blue, about 5 lin. long, sparingly hairy ; tube somewhat funnel-shaped, 24-3 lin. long, with an oblique ring of hairs within; limb spreading, flat, 2-lipped; upper lip 4-lobed, 2-24 lin. long, 4 lin. wide, the lobes ovate or suborbicular ; lower lip entire, elliptic- ovate. Stamens 4; the two upper very small, sterile, included ; the two lower fertile, sometimes almost included, sometimes far exserted. Style exserted or included. Nutlets obovoid, surrounded at the base by a somewhat lobed disk.

Agave marmorata was collected by Roezl in the Province of Tehuacan, Mexico, and has since then been rather rare in collections. Of two plants in the garden of the late Sir T. Hanbury at La Mortola, Ventimiglia, under this name, in 1901, one poled in autumn 1904. The scape Was _ damaged by frost during the following winter, and it produced from the stump a large number of bulbils, by
Juny, 1912.
means of which it has been propagated and distributed. Other plants identical with these have been received since at La Mortola from the Botanic Gardens in Palermo and Paris under the name of A. asperruna. One of the plants derived from the original specimen flowered at La Mortola in June, 1911, and provided the material on which our figure is based. Our plant agrees well with the description of A, marmorata given by Baker in his Hand- book of the Amaryllideae, p. 179: his remark, ‘‘ between A. Scolymus and A. americana,” well expresses its characters. The leaves are glaucous, almost white, and only become greener in dying off on the flowering plant. They are extremely rough, especially on the underside and near the point; the marginal and end spines are also tubercular and rough. The Indians are said to make use of the leaves in veterinary medicine.
The position of A. marmorata is not altogether clear. From the leaves it might be considered a member of the Americanae of Baker, but the small bright yellow flowers preclude this and suggest a closer affinity to the species allied to A. Willdingii, Tod., though here again A. marmorata
differs as regards the arrangement of its flowers on the branches.
Description.—Shrub; stem 0; rosette simple, without suckers or offshoots, 2 yards in diameter and 1 yard high, with about thirty leaves. Leaves spreading from the base, recurved from the middle and with a slightly inflexed tip, lanceolate or oblanceolate-spathulate, 40-44 in. long, above the middle 10-11 in. broad, hence gradually narrowed to a channelled point ending in a conical, greyish brown, very rough spine, ? in. long, not decurrent; constricted towards the base and about 53 in. broad at the neck, about 3 in. thick at the base, convex on both sides, but very markedly and almost broadly keeled on the underside, gradually thinner above, broadly channelled and with the margins erect and somewhat undulate, much repand between the large irregular spines, very glaucous or almost white or with a bluish tint, becoming paler and greener only before decaying, very rough everywhere, especially on the under- side and near the top; marginal spines from a broad horny base, cuspidate-uncinate, brown, rough, rising from a broad
ovate or deltoid fleshy cushion of the leaf margin, $—2 in. distant and 7-8 lin. long, separated by a roundish or acute sinus; the lower and higher marginal spines gradually smaller and the edge not repand between them. Injlores- cence about 12 ft. high; scape relatively slender, about 6 ft. long, green, smooth, with several deltoid acuminate scarious empty bracts, 24-6 in. long, and a few leaf-like bracts at its base; panicle oblong-cylindric, about 6 ft. long and 22 in. broad, with about twenty-six spreading branches, the longest 10 in. long; flowers in dense clusters, bright yellow, with a somewhat unpleasant smell, rather small, 14 in. (including the style 24 in.) long. Pedicels short, bracts minute, soon drying. Perranth-segments united at their base into a short tube, erect, campanulate, fleshy, bright yellow, soon wither- ing at the top; the outer ones ovate-lanceolate, acute, 8-9 lin. long and 3 lin. broad, convex on the back and broadly channelled inside, the interior shorter, more obtuse and broader, with a fleshy keel at the back and a deep furrow inside. Stamens yellow, filaments inserted at the base of the tube, erect, unequal, 15-17 lin. long; anthers yellow, 8 lin. long. Ovary bright and glossy green, subtrigonous or subcylindric, tapering at both ends and below the tube shortly 6-furrowed, 10-11 lin.

The beautiful hardy Heath, Erica ciliaris, is a member of the interesting contingent of British species which elsewhere find a home in south-western Europe. This species in the United Kingdom is, in a wild state, to be met with only in the counties of Dorset, Cornwall and Galway. It extends thence to France, and is most plentiful in Portugal and Spain. An old garden plant, Hrica ciliaris was figured in this work at t. 484 more than a century ago and that figure affords a satisfactory idea of the species as met with in the British Islands, in France, and in Spain. But in Portugal, besides the ordinary form, there is another which, while it cannot be discriminated by any salient sil phological character even as a variety, is from the cultura standpoint so distinct and striking as to deserve a ‘ag in our pages, For the earliest record of this form and . its introduction to horticulture we are indebted to ae ze Mr. G. Maw, who met with it in Portugal in 1872. se once attracted the attention of the late Mr. J. McNab, who in a note written in 1875 calls attention to the fact ie Mr. Maw’s plant has a more compact habit of growth an
Juny, 1912,
that its flowers are not secund as in JL. ciliaris proper. Ten years later this striking form was reintroduced, and in 1882 it was described by Mr. Backhouse as E. Maweana. The plants of the earlier introduction had by this time been almost lost to cultivation. Fortunately, however, some were preserved by Messrs. Cunningham and Fraser in their nursery at Edinburgh, and plants were purchased from them for Kew a number of years ago. Since then it has been largely propagated by cuttings and planted in masses in various parts of the grounds; these from July till October give bright displays of rich colour. For soils that are free from lime Mr. Maw’s Heath may be recommended as per- haps the showiest of the late-flowering sorts, and while even its most ardent admirer will agree that it is not desirable to follow Mr. Backhouse in considering it a species apart from E. ciliaris, there is no doubt that the ordinary lover of flowers must feel that formal system is subject to some degree of limitation since it is found impossible to accord
separate botanical recognition of any kind to this pleasing and striking plant.
Description.— Shrub, dwarf, much branched; branches glandular, pubescent. Leaves 4-nate, spreading or sub- reflexed, shortly petioled, 2} lin. long or shorter, 1 lin. - wide or less, ovate, ovate-oblong, or linear-lanceolate, acute,

The genus Styrax is represented in gardens by some half-dozen species of great beauty and distinction. Of these the best and hardiest is S. japonicum, Sieb. and Zuce., figured at t. 5950 of this work as S. serrulatum, from which, however, it is quite distinct. The others include S. Obassia, Sieb. and Zuce., which is given at t. 7039, and S.Hemsleyanum, Diels, which occupies t. 8339. Neither S. americanum, Lam., nor S. officinale, Linn., which may be grown success- fully in somewhat warmer localities, are very hardy at Kew. The species which forms the subject of our illustration 1s quite distinct from any of the foregoing; it comes nearest to S. japonicum, but is about half the size of that plant in all its parts. It is a compact shrub of shapely form, and flowers at a remarkably early age; the plant which yielded the material for our plate in June, 1911, 1s one which was raised from seed in 1909, but it bad actually flowered, though less freely, in 1910, when only seventeen months old. The seed from which ihe plant was raised was presented to Kew by the Arnold Arboretum and had been
Juny, 1912.
collected by Mr. E. H. Wilson in China in 1908. _ As regards the hardiness of S. Wilsonii we are not yet ina position to pronounce definitely ; Mr. Wilson thinks it may be tender while young but hardy after a firm woody stem has been established. In any case, for the present, it will be desirable to afford protection for young plants during severe frost, though it may be remarked that when, durin the winter of 1911-12, on one occasion 18°-20° of frost were registered, only the tips of the twigs were injured in the nursery at Kew. Propagation can be secured by layers, but it will probably be preferable to rely on seeds, more especially since the plants flower when so young.
Descriprion.—Shrub, small and compact; young twigs subterete, pubescent. Leaves alternate, petioled, elliptic-
ovate, irregularly and sparingly toothed, sparingly pubescent with usually stellate hairs, 3-3 in. long, 4-1 in. wide, secondary nerves 2-3 on each side somewhat raised beneath ; petiole about 4 in.long. Flowers in axillary and terminal short, open, few-flowered racemes, their stalks about 4 in. long. Calyx campanulate, stellate-hairy, 14-1} lin. long, lobes triangular-rhomboid, subacute, very short.

The handsome Cotyledon which forms the subject of our illustration is very distinct from any of the other species of this genus now in cultivation, though among these it is, perhaps, more nearly allied to the familiar C. gibbiflora, Moe. and Sessé, than to any other. But from C. gibbiflora it differs widely in the form and colour of its Jeaves, and in the rich orange tint of its corolla, which is very glaucous on the outside. ‘The branches of the inflorescence are shorter, more erect and stiffer. C. subrigida was first discovered in Mexico, in October, 1892, by Mr. C. G. Pringle, growing on ledges of cliffs in the Tultenango Cafton. The plant from which the material for our figure has been obtained was presented to Kew in 1905 by the authorities of the Natural History Museum, Washington, U.S.A., under the
Juny, 1912.
name proposed by Dr. Rose. It has grown vigorously in the cooler end of the Succulent House at Kew and flowered profusely in October, 1911. Like the other species of the genus in cultivation it is easily grown if placed in a sunny position out of doors during the summer and protected from frost in winter by being transferred to a greenhouse or a heated frame.

- The Pseuderanthemum of which a figure is here given is a native of Selangor, and perhaps also of other parts of the Malay Peninsula, The plant which has provided the material for our illustration was presented to Kew in 1909 by Mr. H. N. Ridley, then Director of the Singapore Botanic Garden; it was sent under the name Eranthemum Teijsmannii, and it is certainly very nearly allied to the species described as E. Teijsmannii by the late Mr. C. B. Juty, 1912. :
Clarke in the materials for a Flora of the Malayan Peninsula edited by the late Sir G. King and Mr. J. S. Gamble, which is, in turn, no doubt also the species referred to as Ei. Leysmannii by Mr. Ridley in his account of an expedition to Temengoh in the Journal of the Straits Branch of the Royal Asiatic Society in 1909. But while the two are so closely related, they differ very materially in the points to which Dr. Stapf directs attention, and more particularly in respect of their habit, for E. Teijsmannii, as limited by Mr. Clarke, is a “shrubby creeper,” and is spoken of by Mr. Ridley as “easily recognised by its climbing habit, scrambling to some height up bushes and often forming a bulky mass.” Whether Mr, Clarke’s species be identical with the original Z, Teijsmannii, T. And.,a plant cultivated in the Royal Botanic Garden, Calcutta, originally sent there from Java, is not clear. All that is definitely known of that plant is that it too is one “with a straggling habit,
and therefore unlike the subject of our plate, which forms an erect shrub some 3 feet in height. Grown in a Tropical House under the conditions suitable for Begonias it thrives well and flowers in April. As a garden plant it is comparable in value with the other species of the genus Pseuderanthemum already in cultivation, an African member
of which, P. seticalyx, Stapf, has already been figured at t. 8244 of this work.
