IMPATIENS corNIGERA.

Hlorn-bearing Balsam.

Nat. Ord. BaLsaMINE®.—PENTANDRIA MOoNOGYNIA.

Gen. Char. (Vide supra, Tas. 4615.)

IMPATIENS cornigera; herbacea erecta inferne ramosa radicans, foliis alternis longe petiolatis ovatis acuminatis marginibus integerrimis scabris basi remote fimbriolatis, petiolis glanduloso-fimbriolatis, pedunculis aggregatis axillaribus unifloris petiolo brevioribus deflexis, floribus (roseis) sepalo superiore (2 sepalis unitis) dorso ungue viridi donato, inferiore cucullato pubescente, calcare brevi obtuso curvato lamina orbiculari.

Raised in the stove of the Royal Gardens, from seeds sent from Ceylon by Mr. Thwaites. It flowered the whole summer and autumn, and may be pronounced a really ornamental plant. In our herbarium we find specimens which we consider to be identical, from Assam, sent by Major Jenkins, and among those specimens are some with glabrous flowers, which have consider- able affinity with Jmpatiens levigata, Wall., but from which the

_ present appears truly distinct.

Descr. Stem erect, three to four feet high, rather stout, succu- lent, semipellucid, striated, often red at the setting on of the leaves, very thick and much branched and rooting below. — Leaves alternate, large, sometimes nearly a span long, ovate, acuminated, epenninerved, pale beneath ; petiole and midrib generally red, the margin very obscurely crenato-serrate, the minute teeth bearing a seta which is long and conspicuous at the base of the leaf; the edge too, as seen under a lens, is every- where ciliated : petiole 1-2 inches long and nearly a line broad, semiterete, margined, the margin bent, with more or less numerous long soft distant fimbrie tipped with a gland. Peduncles aggre- gate, axillary, single-flowered, much shorter than the petiole, a little enlarged upwards, and curved down with the weight of the

flower. ‘The size of the flower is about equal to those of Jmpa- tiens Balsamina, and the colour is yellowish, much suffused with pink. The upper sepal (two united) is remarkable for a large green horn-like projection from the back ; the lower for being downy, and for the short, much-curved, green spur. VW. J. H.

Curr. This, like other tropical species of the genus, requires to be treated as a tender annual. If potted in light rich soil, and kept in a stove and well supplied with water, it attains a considerable size, producing thick side-branches, which in time assume a hard woody appearance. When placed in a favour- able situation as regards shade and moisture, the lower parts of the branches produce aerial roots, which descend till they reach the soil, and then materially assist im supplying nourishment to the plant. As it flowers late, we fear it will not ripen seeds ; but it may be increased by cuttings, which root readily in the summer, but require much care in the winter, as they are liable to damp off.

Aster chrysanthemoides. Willd. in Spreng. Syst. Veget. v. 3. p. 588.

A pretty and singular suffruticose Composita, with flowers nearly as large as a China Aster, and the leaves deeply pinnatifid, like some Anthemis, perhaps, rather than Zanacetum. It was seen by Humboldt cultivated in gardens in Mexico; but Dr.

Wright appears to have found it wild in New Mexico, and from

his seeds our plants were raised in the Royal Gardens of Kew. Planted in the open border they continued flowering during the

=

summer months. —

Descr. A procumbent, or rather ascending, half-shrubby plant, with branching slender stems, nearly a foot long, every- where as well as the foliage slightly downy. eaves alternate, sessile, spreading, their outline oblong, but they are cut ina pinnatifid manner down to the linear rachis into a number of rather distant, spreading, linear, acute, entire or slightly serrated Segments: towards the flowers, on the branches, the segments become smaller, till the uppermost leaf is almost or quite entire

Cunt. This pretty plant is a tender biennial, but sufficiently hardy to flourish in the open air during summer. Unfortu- nately for its maintenance as a garden plant, it produces but

a small quantity of perfect seeds and is not readily propagated by cuttings. J. 8.

Ranuncutus (§ Ranunculastrum) cortusefolius; elatus, foliis cauleque pilosis radicalibus subcordato-reniformibus 3-5-lobatis subradiatim venosis, lobis Inciso-lobulatis dentatisque, caulinis subsessilibus 3—5-partitis, fioralibus

Unquestionably the handsomest of all the Buttercups yet known to botanists. The flowers are not only large, more than two inches across, but of a singularly glossy yellow colour; and although a native as it would seem exclusively of the Canary Islands and of Madeira, it is quite hardy. In the latter country Ribeira Frio seems to be the only locality: in the former Mr. Webb de- scribes it as inhabiting grassy banks in the woody districts. It flowers during the summer months. To the synonyms above given Sprengel adds that of 2. heucherefolius, Presl, Fl. Sicul.

Descr. Root grumose, formed of thick, fleshy, fasciculated fibres. Stem two to four feet high, terete, and, as well as the foliage, hairy with rather pilose hairs, which are dilated -at the base. Radical leaves on long hairy petioles, large, between or- bicular and reniform, three- to five-lobed ; Jobes again divided and cut into several acute lobules, or large sharp teeth, cut and ser- rated, the whole somewhat radiately and dichotomously veined ; upper leaves gradually smaller, sessile, five- to three-partite, the segments lanceolate, coarsely serrated, with parallel veins. Flowers terminal, between cymose and paniculate. Petioles terete.

JANUARY Ist, 1852.

Calyz of five, ovato-lanceolate, very hairy, herbaceous sepals, pale and scariose at the margin. Petals five, large, broadly obovate, very glossy yellow. Stamens very numerous. Head of pistils short, oval. Ovary round-ovate, compressed, laterally hairy, tapering into a recurved style scarcely its own length. Head of fruit similar, but larger. W. J. H.

Cuur. This plant, being of neat habit and flowering freely in a pot, is well suited for being associated with general collections of the smaller alpine plants, which are usually kept in pots for the convenience of removing the more tender species to the protection of a frame during the winter and early spring months. When planted in the open border, it should be protected by a hand-glass, additional covering being provided during severe frosts. It is increased by division of the roots, which should be done in autumn. J. 8.

In the absence of fruit, of which we are yet ignorant not- withstanding our copious specimens, I am still doubtful whether this should be ranked with Myrtus or Hugenia, but I retain it in the genus to which Dr. Arnott and myself referred it in the ‘Botanical Miscellany.’ It forms a charming shrub, native of South Chili and the islands, abundant in Chiloe and in the Bay of Valdivia, where the natives call it Ugni, and the Spaniards Murtilla ox Myrtilla; and the habit is not unlike that of our European Myrtle. Introduced by Messrs. Veitch and Son, through their collector, Mr. William Lobb. It proves quite hardy in their Nursery at Exeter, whence we were favoured with the flowering specimen here figured in July 1851. The flowers are fragrant, and the leaves when bruised are no less so; which ensures its being prized by all cultivators.

Descr. A shrub, varying in height, according to Mr. Bridges, from two to four feet, copiously branched; éranches erecto- patent, clothed with brown bark, young shoots downy. Leaves copious, opposite, spreading, on very short petioles, thick, coria- ceous, ovate, sometimes varying to lanceolate, very acute, im- punctate, nerveless, the margin reflexed, dark green above, pale and when dry almost white beneath. Peduncies axillary, solitary,

single-flowered, with a pair of linear reflexed dracts at the setting on of the flower. Calyz-tube turbinate, dotted : Limé of five (or rarely four) recurved, linear /odes, exactly resembling the bracts. Petals five (or four), erect, orbicular, very concave (forming a globose corolla), white, tinged with rose. Stamens numerous: anthers red. Style shorter than the petals, thick, subulate. W.7.H. Cunt. One of the many new shrubs and trees lately intro- duced from Chili by Messrs. Veitch and Son. It is, no doubt, sufficiently hardy for the climate of the southern and western coasts of Great Britain, and also for other less favoured parts of the island when the winters are mild; but we would recom- mend its being treated, at present, as a greenhouse plant. Experiments should, however, be made in all situations, to ascertain the degree of cold it will bear; for if truly hardy it will prove a great acquisition to the ornamental shrubbery. Like most of the genus, it strikes freely from cuttings. J. 8.

Baccharis-leaved Pentstemon.

Nat. Ord. ScRopHULARINE®.—DipynaM1a ANGIOSPERMIA.

Gen. Char. (Vide supra, Tas. 4318.)

PENTSTEMON baccharifolius; caule erecto tereti pubescenti-glanduloso, foliis gla- berrimis atro-viridibus coriaceis grosse spinuloso-serratis inferioribus spa- thulatis intermediis oblongis summis rotundatis, panicula terminali elongata, calycis brevis segmentis ovatis, corollee (coccinese) tubo infundibuliformi ore obliquo limbo subbilabiato, labio superiore bifido inferiore trifido, filamentis inclusis quinto sterili.

At Tab. 4601 we had the pleasure of figuring a handsome new Pentstemon, P. Wrightii, reared from Texian seeds gathered by Dr. Wright; and now we have the satisfaction of giving another equally new and showy species derived from the same source, and, like that, quite hardy, flowering through the summer and autumn. It is so distinct that we cannot point to any other species with which it is at all likely to be confounded.

Dzscr. Annual? Stems erect, or decumbent at the base, a foot to a foot and a half high. Stem scarcely branched (except where it terminates in the panicle), terete, stout, and rigid, of a purple-brown colour, and, as are the pedicels, bracts, and flowers, even the corolla within and without, clothed with minute glandular pubescence. Leaves in rather distant pairs, rigid, dark green, spreading, coarsely and spinescently toothed or serrated (generally less so at the base), glabrous: the lower ones spathulate, up- wards on the stem becoming oblong, and finally, nearest the flowers, rotundate, obscurely penninerved, all of them quite

sessile. Panicle terminal, elongated ; primary peduncles opposite,

three-flowered, bracteated at the setting on of the peduncles and pedicels ; dracteas small, broadly ovate, reflexed. Calya small, cup-shaped, deeply cut into five imbricating, ovate segments. Corolla rich scarlet, an inch and a half long: ¢ube infundibuli- form, labially compressed, slightly ventricose below, the mouth

rather oblique, marked with a white ring: the /imd obscurely two-lipped ; upper lip two-lobed, lower of three larger lobes, all patenti-reflexed. Stamens included: the fifth stamen is an abortive glabrous filament. Ovary oblong, gibbous on one side at the setting on of the long slender style: stigma capitate. W. J. #.

Cuxr. This new species of Pentstemon is a native of the same region as P. Wright. Judging by the appearance of the plant after the severe frost in November last, we may conclude that it is not sufficiently hardy to live throughout the winter without some protection ; it is therefore desirable to keep a stock in pots, that may be placed in a cool frame during the winter. Being a late-flowering species, it did not ripen its seeds, but, like the allied species of the genus, it. may be increased by cuttings. J. 8.

Raised from seeds sent by Dr. Wright from Texas, and quite hardy, flowering in the open air as late as November 1st, when our drawing wasmade. In foliage the species certainly more closely resembles G. inuloides, Bot. Reg. t. 248, than G. squar- rosa, figured in ‘ Botanical Magazine,’ tab. 1706, but it appears on comparison distinct from both, especially in the great size of the flowers (capitula) and in the deep orange-yellow of the broad ray, no less than in the great height of the plant, three to five feet in our garden. It must be confessed, however, that the Species of the genus are very variable and ill-defined.

Duscr. The root appears to be annual or biennial, fibrous. Stems, on an average, four feet high, erect, herbaceous, simple, till towards the summit where they are corymbosely branched, each dranch leafy and terminated by a flower. Whole plant hard and rigid, subglaucous. Leaves alternate, sessile, from a. broad cordato-semiamplexicaul base, lanceolate, gradually taper- ing to a point ; the base coarsely dentato-serrate, the rest nearly entire. Flowers (capitula) very large, solitary, on each terminal branch, full orange-yellow. Znvolucre hemispherical, glutinous : scales subulate, spreading or even recurved, squarrose, herba-

Ovary obovate, furrowed, bearing one or more sete: style with the branches subulate. orets of the disc tubular, five-toothed, of the ovary as in the ray, sete three to six. Style much longer than the stamens, branches dilated upwards, downy. eceptacle foveolate. W. J. H.

Cutt. A stout plant, growing freely during the summer months in the open air, and making a showy appearance when in flower. Towards autumn the stem becomes hard and woody ; after flowering, the stem and roots are exhausted and die, showing that the plant is only a biennial. Like many Mexican Composite, it does not freely ripen seeds; but it may be readily mereased by cuttings, which should be struck so as to have them established by the end of the summer, the young plants being kept in a cool airy place till the spring, when they may be planted out in the flower-borders. /. 8.

Brrrenarta Hadwenii. Lindl. in Past. Fl. Gard. July 1851, p. 67.

Scuricarta Hadwenii. Hort. (Lindl.)

Communicated by Isaac Hadwen, Esq., of Liverpool, from the stove of his garden, in June 1851. It has a good deal the habit of Mawillaria (Scuticaria) Steelii, figured at our Tab. 3573, and it is no wonder that horticulturists placed it in _ the same genus; but Dr. Lindley observes that it departs from Scuticaria in the pollen-masses, and he refers it to Bif enaria, though differing somewhat from that genus. It is a native of : Brazil, and appears to have been first imported by Mr. Hadwen from Rio Janeiro. We have received plants at Kew from the same country, through our valued friend Mr. Miers, of Temple Lodge, Hammersmith. It flowered with Mr. Hadwen in May, with us in September.

Dzscr. Except that the foliage is shorter and not so flaccidly pendent, the general aspect of the plant is quite that of our Mazxillaria Steelii. The stem or caudew is short, knotty, brown, throwing out a few cylindrical fleshy roots, and from a sheath- ing swollen base bearing eaves a foot and a foot and a half long, terete, furrowed on the inside, acute, dark green.

Curr. This Orchid requires to be kept in the tropical Orchid- house. It is strictly epiphytal, and the appearance of newly- imported plants leads us to suppose that it grows in rather exposed and dry situations. At the Royal Gardens it grows on a suspended block of wood, and has flowered. The wood should be slightly inclined, in order to favour the pendulous habit of the plant. J. 8. |

_ Reared from tubers sent to the Royal Gardens, from Khasya, in North-eastern Bengal, by Dr. Hooker; and these specimens (flowering in September 1851) exactly correspond with drawings made by that naturalist on the spot. They sufficiently accord with the original 2. purpurea of Sir J. E. Smith, to satisfy us that it is identical with that species ; whereas, further north, in Sikkim-Himalaya, Dr. Hooker detected and drew and transmitted living plants to Kew of what has been called R. purpurea by us (im “Exotic Botany’), by Mr. Roscoe (in his fine work on Mo- nandrian plants), and by Dr. Lindley (in ‘ Botanical Miscellany ’). All the plants of these authors agree in being larger and stouter than the one now before us, with swollen stems and ovato-lan- ceolate approximate leaves, and flowers of a pale lilac-purple, With a very large and broad lip, nearly entire at the apex. We hardly dare venture to assert that the two kinds are truly distinct, though I am disposed to think them so: but whether Species or varieties, our present plant, now we believe first FEBRUARY Ist, 1852.

reared in England, is the same with the original 2. purpurea, Sm., and as such it is here figured.

Descr. From a fasciculated cluster of tuberous roots arises a slender leafy stem, about ten inches long, slender, leafy, and clothed with the striated sheaths of the /eaves, which latter are sessile, lanceolate, striated, and acuminated into a very fine narrow point. From two to three terminal, membranous, elon- gated, floral, sheathing dracteas, the flowers arise, altogether of a full purple colour. ‘Tube of the perzanth exserted. Superior lobe erect, fornicate: two izferior ones linear-oblong, patent ; lateral ones short, connivent within the superior; Zip large, de- flexed, obovate, with two indistinct lateral lobes near the base ; the apex deeply two-lobed, the lobes obtuse. Azther large, curved, with two conspicuous spurs at the base. Sty/e passing between the two cells of the anther and terminating in a globose stigma, perforated and ciliated at the top. VW. J. H.

Curr. The Seztaminee are chiefly natives of India, and most of the species that have been introduced into this country require a warm stove; this Himalayan species, however, is sufficiently hardy to thrive in a cool pit, protected from frost. After the decay of the stems, the underground tuber-like rhizome remains in a dormant state during the winter. At this season the soil in the pots should be kept just sufficiently moist to pre- serve the tubers from shrivelling. Early in the spring these should be repotted in fresh soil, consisting of a mixture of light loam and peat, little or no water being given till they begin to grow, and then but sparingly ; for being of a soft fleshy nature,

ane are liable to rot off through any excess of moisture.

Seeds of this pretty Balsam were sent by Mr. Thwaites, from the hilly country of Ceylon, to the Royal Gardens of Kew, where the plants blossomed in the summer of 1851. The name “ fasciculata’”’ is not a very appropriate one; for though some of our wild specimens have the peduncles in opposite pairs, and hence appearing somewhat fasciculate, other specimens are not, and our cultivated plants had them invariably solitary in each axil. The genus or family is described as being destitute of stipules; but in the present species, unnoticed as far as I am aware by authors, yet figured by Dr. Wight’s artist, is a remark- able deflexed and very conspicuous spur at the base of each side of the leaf and decurrent with the stem, which I can look upon in no other light than asa stipule. ‘The plant is found in a great part of the continent of India, as well as in Ceylon, appearing all over the peninsula in marshy grounds, decorating them, as

FEBRUARY Ist, 1852.

Dr. Wight says, with its large showy pink flowers. Colebrooke gathered it in Sylhet; Dr. Griffiths im Khasya; and Drs. Hooker aud Thomson along the whole Himalayan range.

Descr. An erect, soft, succulent-stemmed plant. Leaves varying a good deal in width, always more or less lanceolate, acute, serrated with setaceous teeth, pale beneath. Peduncles as long as the leaves, slender, patent, each bearmg a single pale blush-coloured flower sprinkled in the centre with dark purple and yellow dots. Calyx and long filiform spur tinged with green. Anterior petals spreading like two broad wings, semi- ovate, and with a lobe on one side. Spur curved, sometimes almost as long as the peduncle. W. J. H.

Cuxr. This species requires the same kind of treatment, in every respect, as Impatiens cornigera, Tab. 4623 ; and being of the same nature, we fear it will be difficult to retain it as a garden

_ plant, otherwise than by yearly importing fresh seeds from Ceylon. IS.

We heartily wish all species of Cactaceous plants were as readily distinguished, and as easily defined in words, as is the present remarkably fine and handsome one :—remarkable in the very prominent ridges, the large and regularly arranged spines, the central one very long, flattened, and hooked at the end, and handsome in the size and colouring of its flowers, both in the bud and when fully expanded. It is a native of Mexico, and appears to have been introduced to our collections by M. Galeotti. It flowers with us in the Cactus-house in July.

Dzscr. Our flowering specimen is nearly globose, and almost a span high, deeply furrowed with about thirteen promment, moderately acute ridges, whose edge is waved by the projecting tubercles in which the areole are slightly sunk. These creole are large, oblong, lined with short, dense, dark-coloured wool, from which proceed about twelve or fourteen long and strong spines, bright red when young, afterwards brownish-grey, tinged with red, especially at the base; most of them are radiately spreading, the outer ones the slenderest, the central one 1s remarkably long, four inches in length, flattened, deflexed, and curved into a hook at the extremity. /Vowers large, handsome, between three and four inches long, and as broad from tip to tip of the petals. Calyx-tube dark green, studded with roundish scales, .

red in the middle, white at the margins; these scales gradually pass into bright yellow petals, with a deep red blotch towards the apex, the innermost oblong-spathulate, acute or apiculate, only slightly tinged with red at the tip. Stamens numerous, yellow, crowded beneath the stigma, and scarcely longer than the tube of the flower: rays of the stigma ten to twelve, linear, pale yellow, spreading. W. J. H.

Curr. This species, like its allies, inhabits dry places, often enduring great heat and long drought, and at times deluged with rain ; but, owing to the nature of the soil and situation of the plant, the water passes off so rapidly that but little reaches the soft fibrous roots. In order to cultivate these plants successfully, we must endeavour to place them under conditions as nearly re- sembling those here described as the nature of our climate will permit. Many species of chinocactee will endure a low tem- perature, even to freezing, without being injured; but in this country it is necessary to grow them under glass. As stated at Tab. 4417, it is not generally important as to the kind of soil in which Cactee are grown if it be not retentive of water. A mix- ture of light loam and leaf-mould, with a small portion of lime- rubbish nodules, is suitable for most of them. The general practice is to grow them singly in pots, but where circumstances permit we would plant them on artificial rockwork within the house, exposed to the full influence of the sun, and so arranged as to allow all superfluous water to pass off quickly. A few inches’ depth of soil will be sufficient for the roots. By this method the soil can be kept at a more uniform degree of moisture in winter; the roots being, therefore, less liable to injury from the frequent watering necessary in pot cultivation. In summer, full exposure to the sun, and frequent syringing, will be found beneficial. /. 8.

Reared from seeds sent by Mr. Drummond from the Swan River settlement. We can scarcely doubt its being the D. nobilis of Lindley and of the ‘Plante Preissiane ;’ yet our flowering plant, in May 1851, was considered by Dr. Meisner (author of the Proteacee of the last-mentioned work) as a new species, which he proposed to call Dryandra runcinata. Itis a really

Descr. Our plants have attained a height of about four feet (they reach seven fect, according to Preiss), and are erect, much branched; the éranches woolly, copiously clothed with leaves @ span or more long, spreading, recurved, hard, coriaceous, pe- tiolate, pinnatifid almost to the midrib; the /odes ovate, acute, runcinato-recurved and very decurrent, tipped with a mucro ; the leaves are dark green above, and glabrous, below veiny and white with dense compact fomentum. Capitula large, yellow, on short lateral dranches. Outer leaves of the involucre folia- ceous, lobed or serrated. Sepals glabrous at the base, woolly above, bearded at the apex. Style filiform, much longer than the sepals. Stigma elongated, nearly cylindrical. W. J. H.

Cuxt. A woody greenhouse plant, belonging to a tribe of plants that were at one time in high favour with cultivators. Of late years, however, they have fallen in estimation, owing partly to the belief that they are short-lived, and partly to the introduction of more showy plants. That they are short-lived, if not pro- perly treated, is true; but in the Royal Gardens may now be seen plants fifty years old, and many above half that age. At Tab. 4528 we have described the method of cultivating Proteacee practised by us for many years past. ‘The present plant is grown in light loam, mixed with a small portion of sharp sand. On shifting it into a larger pot or tub, we invariably keep the ball of earth an inch or more (according to the size of the plant) above the surface of the new soil: this is of importance for prolonging the life of the plant, as it prevents any excess of moisture lodging around the base of the stem. In summer care must be taken not to allow the direct rays of the sun to strike against the sides of the pot; for the heat transmitted to the inside destroys the tender spongioles of the roots, and the plant flags and dies.

We can only consider it as a variety of a groupe of plants which is very apt to sport. W. J. H.

In this country our first knowledge of this tree is derived from young plants kindly sent to the Royal Gardens in the autumn of 1851 by the Horticultural Society of London, and his Excel- lency Sir William Denison, Governor of Van Diemen’s Land. Capt. Erskine, R.N., of H.M.S. Havannah, had recently visited New Caledonia and some of the adjacent islands, and had invited Mr. Moore, of the Botanic Garden, Sydney, to accompany him ; and to Mr. Moore’s energy and kindness we are indebted for the re-discovery of this tree and for the possession of

the appearance of those of Araucaria Cunninghami, and are very little different from those of 4. exce/sa, except that this latter is more regular and uniform in its whorls of branches. The young leaves are sparse, rather distant, four lines long, subulate, broad and slightly decurrent at the base, laterally compressed, ending in a fine sharp pomt or mucro, all these with a slightly down- ward curve; whereas the adult leaves on the old branches and branchlets are densely imbricated, even to the very point of the branches; all are short and broadly ovate (fig. 1, 2, 4), obtuse, con- cave on the upper side, .with a blunt or flattened, often oblique, ridge or carina on the underside. Jale cones terminal, oblong, . an inch and a half long, thrice as wide as the branchlet pro- ducing them ; the scales closely imbricated (as the leaves on the branches), cordato-ovate, acute, finely denticulate, bearing at the base ten to twelve subulato-cylindrical anther-cells. Female cones on short, lateral branches, apparently generally in pairs, between ovate and elliptical, from four to five inches long, three and a half to four inches broad, formed of extremely compact. imbri- cated, broadly ovato-cuneate coriaceous scales, membranaceous at the margins, plane or nearly so both above and beneath, the apex suddenly turning up at an angle, and there thickened, and of an olive-green colour, under a microscope seen to be studded with opake resinous dots; this turned-up apex of the scale* is the only portion seen in the entire cone, and it suddenly contracts into a rather long, recurved, subulate, brown mucro. Lodged within the disc of this scale (forming one with the scale) we find two oblong seeds. W. J. H.

Cuxr. It will be advisable to keep young-plants of this new species In a warm greenhouse during winter. The few that have yet come under our notice appear to grow as freely as A. eacelsa and Cunninghami. Light loam, mixed with a small quantity of leaf- mould, suits them ; and by timely shiftings into larger pots, and keeping the branches free from being crowded with other plants, they will in a few years form graceful trees, which may be placed out-of-doors in sheltered situations during summer.

This, like most of the plants from Van Diemen’s Land, must be treated as a greenhouse plant, but being of rapid growth, it soon becomes too large for the loftiest greenhouse, and, con- sequently, must be cut down or planted out-of-doors. If our winters were never more severe than the one just past, this would not be necessary, for when we have a succession of mild winters, Hucalypti sometimes attain a height of twenty feet and upwards, but a severe winter kills them to the ground; it is therefore only in the south and western parts of England, and other localities favoured with mild winters, that this plant may be expected to attain a height that will entitle it to be called a forest tree ; and it would probably do so if planted in a sheltered situation amongst other trees. Plants of it are easily obtained from seeds, which, like those of Myrtacee generally, do not readily lose their vitality by the sea voyage. They vegetate quickly when placed in a moderate heat; and when they are about half an inch high they should be transplanted singly into pots ; if, however, intended for planting in the open air, it is very desirable that they should not be kept there long in small pots, for the main or tap root, by being confined, forms a spiral coil, which thickens with the growth of the plant, and ultimately proves a very msecure support to the tree, which, on account of

its rapid growth, and the resistance of its d Re bl to withstand high winds. J. 8. its dense foliage, is unable

This is another interesting plant of Van Diemen’s Land, which braves the cold of England, and even the vicinity of London, provided it be trained against a wall. In such a position it has long been cultivated in the Royal Gardens of Kew, flowering copiously late in the autumn. We wish it had more beauty to recommend it. It was raised from seeds sent by Mr. Gunn, by whom, as its name implies, it was first detected. We think Dr. Hooker has properly referred it to Olearia, and that Hurybia subrepanda, De Cand., is merely one of the many forms of the same variable species: variable especially in the size and incision of the leaves, and scarcely less so in the length of the peduncles and the more or less crowded flowers. Sometimes the blossoms are as copious as the leaves.

Curr. A native of Van Diemen’s Land, and, like the preceding species, sufficiently hardy to thrive in the open air of this cli- mate in mild winters. It forms a low evergreen bushy shrub, well suited for the front row of shrubbery borders. In summer, when in flower, it presents a very showy appearance, which makes it worth while to keep a stock of young plants under protection to meet the casualties of a severe winter. It flowers freely if treated as a greenhouse plant, and is readily increase from cuttings. J. 8.

A hardy shrub, no doubt, as Dr. Lindley designates this hand- some plant; but it is only in the milder regions: of the south- west of England and Ireland that we are privileged to see it flowering copiously and bearing its beautiful-looking fruit in the open air. The fruiting specimen here figured was sent from the Belfast Botanic Garden, in December, 1849, by our friend Mr. Ferguson. We have received equally fine ones from Mrs. Buck,

of Moreton, North Devon; and we know that at Heligan, in

Cornwall, and at Sir Charles Lemon’s, Carcleugh, the large and highly-coloured fruit is abundantly produced. Dr. Wallich, who discovered it on Chandaghiry, in Nepal, speaks of the tree as of the size of an apple-tree, and covered with yellow heads of scent- less blossoms in June. We possess copious specimens, gathered by Dr. T. Thomson at Kamaon and Mussoree, by Major Madden at Simla, and by the late Mr. Griffith in Bootan. A second species has been discovered by Dr. Siebold on mountains of APRIL 1st, 1852.

Japan (B. Japonica, Fl. Jap. t. 16), only differing from this, it would appear, in the entire, not four-lobed limb of the calyx; for assuredly the Malpighiaceous hairs on which the author lays stress, as characteristic of B. Japonica, are found equally on the present species. The fruit, tempting as it looks, is only eaten by the inhabitants of the Himalayan hills.

Drscr. We believe that in favourable situations this has at- tained in England a height of twenty feet; more usually it is a low bushy shrub, copiously branched. Zeaves oblong or broad- lanceolate, acuminate, quite entire, shortly petiolate, pubescent on both sides, but most so and nearly hoary beneath, with very close-pressed shortish hairs, many of which are Malpighiaceous. Peduncles terminal, solitary, bearing a dense globose head of small whitish flowers, surrounded by a large four-leaved involucre, each leaf broadly obovate, buff-coloured and subcoriaceous, veined. Tube of the calyx obconical, somewhat angular by mutual pres- sure of the adjacent flowers. Zim four-lobed, scabrous. Petals four, concave, ovate. Stamens four, as long as the petals. Style short, columnar, surrounded by a tubular lobed and furrowed disc or nectary. Stigma peltate. Fruit nearly as large as a nec- tarine, formed of the united large acini, which exhibit their four- sided apices on the surface, of a deep red-orange colour. W. J. H.

This species of Hakea is a native of the Swan River Settle- ment, and has been sent in seed with corresponding dried speci- mens (numbered 600) by Mr. Drummond. Our no. 461 and 272 from the same collector, may be the same or varieties. It 1s evidently the plant described by Dr. Meisner in the ‘ Planta Preissiane’ above quoted, from specimens of Mr. Drummond in Mr. Shuttleworth’s herbarium. ‘The author, indeed, thinks It possible it may prove to be a variety of H. sulcata, but to us it appears unquestionably different, and the distinguishing characters are well pointed out by Dr. Meisner. He correctly observes, “ Folia sepius insecti cujusdam acu hinc inde tume- facta legumina quaedam lomentacea imitantia.”

Marana sanguinea. Hortul.

From the collection of Mr. Jackson, of the Kingston Nursery, and a very handsome and desirable inmate of the stove it 1s. He received it from the Continent, under the name of Maranta sanguinea ; but of what author, or where, if anywhere, it is pub- lished or described, I have not been able to ascertain. It is assuredly rather a Phrynium than a Maranta, and not very distantly removed from our Phrynium capitatum, figured in the ‘Botanical Magazine.’ That species, however, differs in the colour of the flowers and the leaves, in the inflorescence, and materially in the shape of the blossoms. ‘The plant is handsome in its flowerless state, from the rich blood-colour of the long sheaths of the petioles, and the deep purple of the underside of the leaves; but the inflorescence adds greatly to the beauty, the

Bracteas all red, primary ones (at the base of the main ramifications) large, ovate, acute, con- duplicate ; lesser ones, or dracteoles, of the same form and colour. Rachis short, and pedicels articulated, red. Flowers red. Ovary small, turbinate, longitudinally furrowed. The outer sepals broad, ovate, obtuse, nearly equal, free to the base, erect. Inner sepals erect, very unequal, one of them deeply two-lobed, com- bined for a good part of their length from below among them- selves, and with the. broad and flat petaloid filament and style. Anther solitary, lateral. Style curved. Stigma grooved.

_ During the early part of the present year (1852) seeds of an Australian Nymphzaceous plant were in the hands of several cul- tivators in this country as a new Victoria, Victoria Fitzroyana, with flowers of a “ purplish-blue,” from what source obtained I have

not been able to ascertain. Those which were obligingly presented to us by Mr. Carter and Mr. Stokes under that name were, we think, not the seeds of a Victoria, but of a Nymphea, and were so crushed in a letter, and sent dry, that we have no hope of their germinating. Now it does happen that we received during the past year specimens of a magnificent new Nymphaea from our

friend Mr. Bidwill, gathered in the Wide-Bay district, North. _

eastern Australia, some of whose flowers certainly vie with the ordinary ones of Victoria regia, being a foot in diameter, and if not of a purplish-blue colour, yet blue,—the blue, as it would appear, of the well-known Nymphea cerulea. We are much dis- posed to think that this is the plant producing the seeds in ques- tion, and that the plant having been known to other colonists m Australia, the seeds have been by them sent to their friends in this country, under the name of Victoria Fitzroyana. Mr. Bid- will is too good a botanist to have done so. Be that as it may, _ We deem it a matter of duty now to lay a figure and description % gs “MAY Ist, 1852, é :

of our magnificent plant before the public, and even a coloured figure ; for so beautifully are the specimens dried by our valued friend and correspondent, that. we think we cannot err much on that point. And sure we are that, even should all the seeds above alluded to fail to germinate, or prove to be those of another plant, our Wymphea gigantea will ere long find its way into our tropical tanks, and adorn them with a Water-Lily little inferior to the royal Victoria in the size or beauty of its flowers, and with leaves equally remarkable in size, for a true Vymphea, being eighteen inches to two feet across. Dzscr. A tuber which we have lately received from Mr. Bid- ‘will for cultivation, but unfortunately dry and dead, is about the size of an ordinary apricot, and nearly as globose, having nu- merous depressions or eyes, like the ‘‘ eyes” of the potato, with a scale at each depression. ‘The leaves of our dried specimens are eighteen inches across, nearly orbicular, but longer than broad, with a deep fissure at the base, the margin remotely toothed, the substance very thick, and when dry coriaceous ; the _ upper surface green, rather obscurely reticulated, the whole ~ surface appearing minutely dotted with raised points: beneath purplish ; the principal veins, very thick and prominent, radiate from the insertion of the petiole, and form elevated irregular hexagonal reticulations all over the under surface, which surface is everywhere minutely wrinkled. Pefio/e nearly an inch across, terete, full of air-cells (as shown at fig. 1) ; its attachment to the leaf is within, or at a distance from, the base of the fissure, and thus constitutes a peltate leaf. FY/ower twelve inches in diameter (in a dried state). Calyx of four leaves, or sepals, as long as the petals, broadly ovate-oblong, obtuse, green or purplish-green ; one has the two margins and another one margin petaloid. Petals blue, very numerous, spreading, the outermost the largest (a few of them herbaceous at the back down the centre), obovate-oblong, that is, broadest above the middle, striated with veins, the inner ones rather shorter than the outer, linear-lanceolate, all of them ob- _ tuse. Stamens exceedingly numerous, more so than I have seen _ in any Nymphzaceous plant, forming a dense mass around and over the stigma; filaments filiform, short, incurved (none of them petaloid); anthers all perfect, linear, yellow, singularly curved, falcate; those in the centre obtuse ; outer ones apiculate by a slight prolongation of the connectivum. Stigma so covered by the copious stamens that the structure cannot be seen with- out destroying the specimen.—Enough is here shown in proof that the species is very distinct from any of the hitherto known blue Water-Lilies, or of the genus. _

RHODODENDRON ciuiatum; B. roseo-album.

Nat. Ord. Ertcace#.—DrcaNnpRIA Monoeynia.

Gen. Char. (Vide supra, Tas. 4336.)

RHODODENDRON ciliatum; ramulis pedunculis pedicellisque piloso-hispidis, foliis elliptico-oblongis subcoriaceis acutis ferrugineo-pilosis ciliatis demum glabratis subtus lepidotis, pedunculis terminalibus umbellatis 2-6, calycis pilosissimi lobis amplis ovato-rotundatis subfoliaceis, corolle campanulatee tubo inferne angustato limbo amplo 5-lobo, filamentis (10) basi pilosis, stylo gracili, capsula brevi crassa calyce duplo, longiore 5-loculari infra apicem contracta.

It is scarcely two years since the seeds of this Rhododendron were received from Dr. Hooker, and already (March 7, 1852) six plants of it have produced flowers while only seven inches high, and many others are showing blossoms. Their flowering has given us peculiar pleasure, as the first of the Sikkim- Himalayan Rhododendrons which have done so; and on another account. From more than one quarter hints have been thrown out that the author of the work above cited has used some freedom in going beyond nature in the size and colouring of the flowers. Such gratuitous statements, from very incompetent judges, are contradicted by the first species that has blossomed ; for assuredly our cultivated 2. ciliatwm far excels in size of the corolla, and delicacy of tint, Dr. Hooker’s original figure. Even were the reverse the case, it would be no proof of any inaccuracy in Dr. Hooker’s figures, for no intelligent traveller in Sikkim can fail to observe how liable the flowers of all the species of Rhododendron are to vary in size and colour (nor are the leaves more constant): in the present instance the difference is so great, though there cannot be a question of the identity of

MAY Isr, 1852.,

species, that we feel ourselves, as it were, compelled to make it a variety. ‘The corollas are nearly, if not quite, double the size of the native plant as seen by Dr. Hooker, and instead of being . of a uniform lilac-purple colour, they are of the most delicate white, tinged with red-rose colour. In all other respects the two plants perfectly agree. It is a native of wet rocky places (rarely in woods) of Sikkim-Himalaya, in the Lachen and Lachoong valleys ; elevation 9-10,000 feet. It may be expected to be hardy therefore ; and, indeed, we may observe, that young plants of nearly all our species from Sikkim-Himalaya have passed this winter in the open air, simply surrounded by a bank of earth a foot and a half high. &. Dalhousie alone has failed in such a situation, and in many cases we know that it has equally failed under glass. &. ciliatum has been kept in a cool green- house, and has certainly the merit of being a ready flowerer, and that at a very early age.

Dzscr. Even in its native country this species does not seem to attain a height of more than two feet, growing in clumps, and yielding a faintly resinous and agreeable odour. The whole plant, but especially the younger shoots, are more or less pilose with long ferruginous hairs. The /eaves, two to three inches - long, eventually become glabrous on the upper surface ; beneath they are clothed with minute ferruginous scales. Vowers ter- minal, arising from a scaly imbricated bud. Peduncles rather stout, very villous. Calyx large, almost foliaceous, cut nearly to the base into five almost rounded, spreading, obtuse /odes, villous on the outside. Corol/a campanulate, but with the tube subin- fundibuliform; very large in proportion to the leaves, in its native country usually of a uniform lilac-purple: with us of the most delicate white, tinged with as delicate a rose-colour, espe- cially at the back of each lobe. Stamens included ; filaments hairy at the base ; anthers rather small, purple. Ovary oblong, contracted at the apex. Style declined, longer than the stamens. Stigma five-lobed, peltate.

One of the many interesting discoveries in China of Mr. Fortune on his first visit to that country, though not then a new discovery ; for, according to Dr. Lindley, it had been distributed ma dried state from the Imperial Russian Chinese Herbarium under the erroneous name of J. angulare, a species of the Cape — Hope, with white flowers growing on the peduncles in

es. :

When first described by Dr. Lindley, in the valuable journal of the Horticultural Society of London, it was considered a valuable greenhouse plant, a winter bloomer, and pines a flower for a length of time. But in the ‘ Botanical Register’ the further information was given that it was likely to prove hardy ; for “this species,” writes Mr. Fortune, “was first discovered in gardens and nurseries in the north of China, particularly about — Shanghae, Loo-chou, and Nanking. It is a very ornamental

dwarf shrub, and I have no doubt of its being perfectly hardy in —

MAY Ist, 1852,

this country (England). It is deciduous ; the leaves falling off in its native country early in autumn, and leaving a number of large prominent flower-buds, which expand in early spring, often when the snow is on the ground, and look like little primroses.”

Nothing can be more accurate than this statement. The shrub proves perfectly hardy; it flowers in the middle of winter (our drawing was made from a plant on the open wall in December, 1851), and the fallen blossoms on the frosty and snowy ground look like primroses. It is to be regretted that the foliage, scanty at best, does not appear at the same time with the leaves. Our specimen, not fully developed, was drawn in April. The plant is, like other Jasmines, easily propagated by layers or cuttings.

Descr. A twiggy shrub, from four to eight feet high, with long, opposite, dark-green dranches, exactly quadrangular, the angles somewhat winged. eaves opposite, petiolate, trifoliolate. Petiole rather shorter than the leaves. Leaflets ovate, the middle somewhat obovate, acute, glabrous, ciliated. Mowers lateral, opposite, solitary, arising from scaly buds, on short rather thick petioles. Scales ovate-acuminate, tinged with brown.

A native, it is said, of the Moluccas, whence it appears to have been introduced to the Belgian gardens by M. Van Houtte, and through that channel to our stoves in England. It forms a hand- some shrub, with large dark green leaves, and drooping racemes of waxy rose-coloured flowers, having dark purple anthers. Our increased intercourse with the Malay Archipelago has been the means of adding considerably to our knowledge of the species of this fine genus. Twenty-four species are enumerated in Walpers’ ‘ Repertorium,’ and eleven additional ones are given mn the ‘Annales’ of the same author—thirty-five in all. Most of them are described in Blume’s Mus. Bot. Lugd. Bat., a work of great value to the student of the botany of the Dutch possessions in the Malay Islands. For the mode of cultivation, see under our Tab. 4569. With us this species flowers in the spring, and continues long in blossom. .

Duscr. Our plant is between three and four feet high, shrubby, with the stem and opposite branches quite terete ; the - branchlets only are here and there seen to have an indistinct angle. At the nodes of the stem and branches, between the

petioles of the leaves, is a dense tuft of soft spicules of a dirty brown colour. Leaves (on short thick peto/es) four to five or six inches long, coriaceous, glabrous, between ovate and ellip- tical, quite entire, acute at the base, shortly and suddenly acumi- nate at the apex, strongly five-nerved; zerves very prominent beneath, where the colour is pale green, while it is dark green above. Peduncle terete, as long as the finger, and, together with the thyrsoid panicle of flowers, drooping. Pedicels about as long as the calyx, which latter has the tube nearly globose, fleshy, pale rose; the very short margin or limb erect and erose. Petals four, spreading, broad-ovate, acute, rose-coloured. Stamens eight, pointing and spreading to one side: filaments subulate, white, curved: authers also subulate, deep purple, wrinkled on the upper side: at the base above formed into two incurved lobes, below furnished with a straight spur. Ovary combined with the calyx: style curved, subulate: stigma obtuse.

A singular-looking, rather than beautiful, hoary shrub, with large purplish flowers, at first sight not unlike those of some Solanum ; native of Swan River, whence seeds have been sent by Mr. Drummond to Kew, and reared in 1847. Our first flowers appeared in March, 1852, in an ordinary greenhouse. ‘The genus Guichenotia, s0 named by M. Gay in compliment to the gardener of M. Baudin’s expedition, M. Antoine Guichenot, was founded upon the G. ledifolia, equally with this an inhabitant of the Swan River district, and is described by Mr. Turezaninow from —

Our last representation of a Brachysema from Swan River (Tab. 4481) was of a very handsome species, and a very singular one, destitute of foliage. Our present is also a handsome one, and its beauty is enhanced by the good-sized almost polished leaves, dark green above, beautifully silky beneath. It is, equally with the former kind, a native of Swan River, and was raised from seeds sent home by Mr. Drummond, in the Exeter Nursery of Messrs. Lucombe, Pince, and Co., where it flowered for the first time in February, 1852. It is one great charm of the Australian plants that they so generally flower when there 1s little else to

enliven the conservatory, and this cannot fail, on that account, _ to be very acceptable to cultivators. Dr. Meisner had evidently very imperfect specimens to describe from, for he was ignorant

of the colour of the corolla, which in the living and in the dried

Specimens of Mr. Drummond is of the richest scarlet; and he - describes the flowers as solitary. Yet he has contrived to form three varieties. ‘The leaves are certainly variable in form, even on the same individual branch. ied

Of the genus Acacia, reduced as it is by the removal of numerous species to other genera, Mr. Bentham has, in his valuable Memoir on J/imosee, enumerated no less than 340 Species in the first volume of the ‘ London Journal of Botany,’ published in 1842; and many have since been added. These he has, with much skill and judgment, divided into six series, and those into sections. Of these, the first three series, con- taining 228 species, belong to Australia, and of them 204 are phyllodineous species, that is, they have the leaves reduced to leaf-like petioles. The third series of the genus, “ Pulchelle,” is characterized by being “unarmed, or furnished with axillary spines ; the leaves bipinnate; the inflorescence capitate or spi- cate and simple; the capitula or spikes axillary, arising from a bracteated bud or gemma.” Here eleven species are enume- rated, including the present one. 4. Cycnorum, as its name im- plies, is an inhabitant of the Swan River settlement, where it appears to be common; and Meisner gives two varieties: but Mr. Bentham is rather inclined to think that this ought to be considered, along with 4. Jasiocarpa and A. hispidissima, among the varieties of 4. pulchella of Mr. Brown. Be that as it may, it is a very handsome plant, and deserves a place in every green-

Petiole very short, without gland (in what we have examined). Rachis hairy. Pinne two pairs ; the lower pair each with three, the upper with four, pairs of small oblong leaflets, when dry revolute at the margin. Peduncle rather longer than the leaves, axillary, slender, arisg from a scaly gemma. Head of flowers globose, rather deep yellow. Flowers crowded. Calye turbinate, five-lobed, with spreading hairs in the upper half; the lobes short, very obtuse. Corolla four-lobed ; °/odes concave, ovate, erect. Stamens numerous. Style rather longer than the stamens.

With us this forms a good-sized greenhouse shrub or small tree, with very copious dense evergeen foliage, and in a state of fruit really handsome from the copious purple-red fleshy recep- tacles of the seed, which are produced in the winter months. The species is a native of Nepal, and was many years ago introduced to the Royal Gardens by Dr. Wallich. It appears to

a mountain plant, and it is not impossible but it may prove hardy enough to bear the open air, against a wall. It is with us treated like the Australian and New Zealand plants. The female flowers appear very apt to coalesce, and the receptacles then to bear two berries; and even when there is one, the receptacle seems to be often unnaturally enlarged, and to be much: de- formed. The male amenta are described from Dr. Wallich’s _ JUNE Ist, 1852.

Male amenta axillary, sessile, solitary, cy- lindrical, slender, an inch or more long, arising from a cup- shaped scaly involucre. Azthers numerous, imbricated, two- celled, much acuminated, at length reflexed. Pedwncle of the female solitary, axillary, single-flowered, about half an inch long. Receptacle of the fruit oblong, fleshy, soon enlarging, especially in breadth, with an oblong depression at the top, and variously lobed on each side, from pale yellow-green becoming orange-red, at length deep purple, slightly glaucous, bearing a small subulate recurved bractea at the base. At the apex it bears an obovate glaucous-green seed. Sometimes two or more receptacles grow from the same peduncle, and such a one we have seen to be proliferous at the extremity.

Originally detected near the summit of the mountain Sheopur, Nepal, by Dr. Wallich, after whom the species 1s appropriately named by M. De Candolle. By Mr. Veitch it has been intro- duced to our Gardens, through his zealous collector, Mr. Thomas Lobb, and, about the same time, by Dr. Hooker from Eastern Himalaya. It is a most ready flowerer, producing blossoms i April, when not more than eight or ten inches high, in small pots ; but in its native country the plant attains a height of from six to eight or ten feet. As far as our experience goes, and that of Messrs. Veitch, this species may be expected to prove hardy, and thus add another interesting flowering shrub to our arboreta. The foliage a good deal resembles that of the Fuegian Bert. ili- cifolia, figured at our Tab. 4308 ; b inflorescence is very Say an : ’ Descr.

The purple-flowered state of this very variable species of Rhododendron blossomed freely in April, 1852, in a cool green- house of the Royal Gardens. ‘The seeds were sent from Sikkim- Himalaya by Dr. Hooker, under the name of &. eleagnoides, and as such this is figured in the work on the Rhododendrons, with dark purple flowers, and also with deep.yellow flowers, looking like those of some Helianthemum. In that work, how- ever, the author alludes to its close affinity, as well as that of R. salignum, with the R. lepidotum of Wallich (only known to us from dried specimens) ; and a further examination has satis- fied him that they and his 2. obovatum can in no way be speci- fically distinguished from authentic specimens of /epidotum. He has therefore, in the ‘Journal of the Horticultural Society of

ndon,’ united them.

“The species abounds,” Dr. Hooker says, “at an elevation of

It isa slender or stout twiggy shrvd, one to four feet high, branching, often growing in widely extended clumps, as heather does with us, but never so extensively ; and it emits in sunshine a powerful resinous odour. eaves of a pale glaucous green, lighter under- neath, and sometimes ferruginous where the scales abound, one- half to one and a half inch long. ower-stalks more or less elon- gated, one and a half to two inches long, slender. Corolla yellow or dirty purple, half an inch across the lobes, scaly, espe- cially on the outside of the tube; the upper lobes are spotted with green.—The odour of this plant is strongly resinous, and rather sweetish and pleasant. Its common native name is Tsaluma, or Tsuma, amongst the Bhoteas.” Look. il.

Kew, which are recently sown, from our valued friend Mr. Thwaites, of the Botanic Garden in Ceylon. These seeds were accompanied by a coloured drawing of the plant, which enables us to give the representation of a plant of some interest in the Materia Medica,—the same kind of interest I mean as is felt in the detection of the adulteration of Tea, Coffee, Tobacco, etc. ; for there has been of late a very extensive importation of what we here term “ false Calumba-root,” instead of the true Calumba- root, Jateorrhiza palmata, Miers (Flora of the Niger Expedition), Cocculus palmatus, De Cand. (and of this work, Tab. 2970, 2971). Daniel Hanbury, Esq., of Plough-court, London, in a recent volume of the Pharmaceutical Journal, gave a history of this fraud on the public; and immediately opened a correspondence with Mr. Thwaites on the subject of the plant in question. The Coscinium was scarcely known to botanists but by the brief description of the curious ‘seed (curious as to internal structure, published by Gertner, 1. c.), and the still imperfect de- scription of the plant by Mr. Colebrooke in the ‘ Linnean Trans- actions,’ and Dr. Roxburgh in his ‘ Flora Indica,’ from specimens and information communicated to those Indian botanists from Ceylon by General Macdowall. A notion had prevailed, derived from the name of the Calumba or Columbo plant or root, that it was derived from Columbo in Ceylon, and a native of that island. At length, as shown under our Tab. 2970, 2971, it was ascertained that the true plant was a native of Mozambique, where it is known by the name of Kalwmb, or Kalumba. General Macdowall then sent our present plant to his scientific correspondents in order to ascertain whether this, much celebrated in the Cinghalese Phar- macopeela, was not the ¢rve Calumba-root, and for that purpose consigned “ a pretty large bit of the root,” sawed from the centre of a knot, to Dr. Roxburgh, that he might make experiments with it. Dr. Roxburgh, in a note, Fl. Indica, p- 811, at once sets the question at rest: “This is certainly not the Calumba- root ot our Materia Medica.” Nevertheless there have been large importations and ready purchasers for the Ceylon drug into England, the real properties or virtues of which (belonging though the plants do to the same Natural Family) are, to say the least, very problematical.

{It now only remains for us to give Mr. Thwaites’s remarks and descriptions in his own words. Ep.

“This species is very abundant near the sea-coast in Ceylon, and occurs also in the Central Province. 'The specimens from which the accompanying figure was taken were procured about twelve miles from Kandy. The Cinghalese value this plant very highly, using a decoction of the knotty parts of the stems (not the root*) as a

* In the ‘ Flora Indica’ it is implied that the roots (not the stem) are em- ployed, as is the ease with the true Calumba-root.

;

tonic and anthelmintic. The wood yields an inferior yellow dye.” Thw. .

Some further remarks on the uses of this plant are given by Mr. Thwaites in a letter (dated Peradenia, August 14, 1851) to Mr. Hanbury, in reply to some queries of that gentleman. “The Menispermum fenestratum, Roxb., is taken here, I am told by an intelligent native, mixed with other things, in a great many com- plaints, and applied externally in some cases, such as for weak eyes, etc. The mode of preparing it, is to chop up the wood at the knots of the stem very small, and to boil it (with other things, which was particularly impressed upon me) in seven measures of water, until they are evaporated down to one measure. It seems to be one of the numerous universal medicines employed here in any and every complaint. It is quite impossible to get at any definite information from the natives as to what particular com- plaints certain plants are useful in. The priests, who are the doctors, appear to me to mystify the poor people by directing them to take certain leaves and roots which it often gives them no little trouble to find; and I think that the mind being em-

ployed in the matter, as well as the bodily exercise the patient

often takes to procure the valued remedies, and a certain mixture of faith, have more to do with the cure than the drugs, some of which are evidently perfectly valueless except to feed cattle.”

Descr. Zrunk and large branches scandent, stout, thick, lig- neous, and knotty. The wood of a deep, lively yellow colour, and of a pleasant bitter taste. Leaves alternate, petioled, cordate, entire, five- or seven-nerved, smooth and shining above, very hoary underneath, sometimes acuminate, sometimes obtuse ; from three to nine inches long, and from two to six inches broad ; in young plants frequently peltate. Petioles shorter than the leaves, round, downy. Unmbellets or heads of flowers axillary, several from the same bud, on thick round downy peduncles of about an inch in length. /owers numerous, subsessile, villous, of a brownish green. Sepals brown, villous ; the three interior larger, pale within, and reflexed. Matz. Heads of flowers smaller than in the female plant. Stamens six; the three inner cohering nearly to their summits ; the three exterior nearly free, somewhat recurved. Frm. Sterile filaments strap-shaped, hairy. Styles much reflexed, becoming dark brown. Drupes nearly round, villous, of the size of a large filbert. As the fruit advances in size, the very short pedicel of the original flower lengthens into a pretty long, stout, cylindric, villous pedice/, ending in a round- headed receptacle, on which the one to three drupes are situated, Surrounded by the permanent calyx.

: A most delicate and lovely Dendrobium, sent in 1847 by Dr. Gas M‘Clelland, from the Calcutta Botanic Garden, to W. G. Farmer, Ee Esq., after whom it was named. Mr. Paxton observes, that “in | habit and appearance the plant very much resembles Dendrobium densiflorum’’ (see our Tab. 3418), “but the stems are more an- gular, and the flower-scape is less densely laden with bloom ; the flowers, too, are altogether different.” The flowers, how- ever, are more different in colour than they are in shape ; and if true to its other characters, there is no difficulty in distinguishing this species. In the stove of the Royal Gardens of Kew it flowers in May. = Diece. Our plant has elongated club-shaped stems, jointed and deeply sulcated, growing in clusters; at the base they swell out into a kind of pseudo-bulb, scarcely so large as a hazel-nut. The young stems bear from two to four spreading, ovate, corl- aceous or fleshy /eaves at the top, acute, striated ; the old stems throw out pendulous racemes from near the summit, which exceed the stems in length. //owers numerous, but rather lax. Bracteas small, ovate, concave. Sepals very patent, broad, ovate, obtuse, pale straw-colour, delicately tinged with rose. Petals of the JULY Ist, 1852,

The discovery of this pretty and, as it proves, hardy evergreen shrub is due to the venerable Mr. Nuttall, who found it at Santa Barbara, Upper California. Our plants are derived from the Horticultural Society, who appear to have received the seeds from Hartweg, while he was in California, under the name of “ €. tntegerrimus ;” but by that name he could not intend the plant so called of Hooker and Arnott, in the ‘ Botany of Beechey’s Voyage.’ The plants have borne the open air in the Arboretum at Kew for two winters, and flower readily in April and May. Our specimens have'been carefully compared with Mr. Nuttall’s original ones, and they seem entirely to agree. — The foliage in our plants is rather larger and generally more orbicular, a change that may be due to cultivation ; and in both the leaves are very variable, even on the same specimens. Our flowers are very pale purplish-blue. They would appear “ white” in the dried plant, as described by Torrey and Gray.

We have here another of the many curious species of Balsam which abound so much in Ceylon, and we may say perhaps in the moist and mountainous parts of India generally. Our gar- dens are indebted for seeds of this to Mr. Thwaites, the able superintendent of the Botanic Garden at Peradenia, who sends _ it to us from Adam’s Peak (no. 436 of Mr. Thwaites’ dried col-

2 lection), and Mr. Gardner’s specimens (no. 159 of his collection)

are from Newra Ellia, at 6000 feet of elevation. We had, many years ago, received Ceylon specimens, without any particular locality, from Mrs. General Walker. Our plants flowered, at the Royal Gardens, in a moist but not very hot stove, in the early summer of the year after the seeds were sown; and, small though the blossoms are, yet their deep tawny orange-colour, — stained with red, and the numerous long bright petioles, to- gether with the ample foliage, render this a handsome plant. - Descr. Our plants attain a height of from two to three feet: in their native country they are probably much taller. The stem is erect, straight, as thick as, or thicker than, one s finger, pur- — plish. Zeaves mostly at the top of the stem, below them are the Scars of many fallen ones: they are crowded, alternate or scat- — august sr, 1852. :

tered, large, five to six inches long (some of our native specimens measure nearly a foot), ovate, much and gradually acuminated, pilose on both sides, dark green above, paler beneath, closely penninerved; the margin everywhere serrated, the serratures mucronate ; at the base the margin is fringed with long soft bristles, tipped with a gland, and is gradually attenuated into the long, stout, bright red /eaf-stalk upon which are a few scattered glandular sete. Peduncles axillary, aggregated (often densely crowded), much shorter than the petioles, single-flowered, having minute dracteas at the base. Flowers small for the size of the plant, deep tawny orange, stained with red. The upper sepal is oblong, convex, red, terminated with a long claw-like point. The lower one, or /adellum, is cucullate, the mouth ending in a sharp recurved acuminated point, like the mouth of a ewer: ' the spur is short, hispid, with a few long bristles, singularly in- curved, almost upon itself, and swollen and didymous at the . apex.

Specimens in our herbarium from Dr. Wallich show that this is the Dendrobium transparens of that author, a native of Nepal, which Dr. Lindley compares with D. Pierardt, a similarity more apparent in the dried than in the recent state. It is a native of Nepal, and probably many other parts of Eastern Bengal. Our plant was received among a collection of living Orchidee, sent to us from Assam by Mr. Simon. Few species are more lovely, even among the oriental Epiphytes, which are proverbial for their beauty over those of the New World. | The ground- colour is a transparent white, but all the petals and sepals and lip are tinged with rose-colour towards the apices, and the inside of the labellum has a large deep blood-coloured blotch passing ~ into strie at the edges. With us the species flowers profusely during the summer months, and the flowers are copious on the stem. ;

We are indebted for the possession of this pretty shrub to the Horticultural Society of London, who introduced it to the English gardens through Mr. Hartweg, of whose dried collections it is no. 1680. It inhabits Monterey, in California. Besides the specimen from Mr. Hartweg, and original ones from Mr. Nuttall, we possess the plant from Dr. Coulter, Mr. Douglas, and Mr. Lobb. It is far more rigid and branching even than our common Sloe (Prunus spinosa); but then the densely placed glossy evergreen foliage, and rich deep purple-blue and copious blossoms, early in May, render it a most desirable species for our gardens and shrubberies. Our figure is from a good-sized shrub, which has braved two winters unharmed in a very exposed part of the Kew arboretum.—The North-west American Ceanothuses are particularly deserving of cultivation in the open ground ; but it may require a Devonshire climate to bring them to the state in which they are at Bishopstowe, as just announced to me in a letter, dated 27th May, 1852, of the Bishop of Exeter. “The Ceanothus divaricatus is now in its highest beauty: the largest

Our young plants are’ two and a half feet high, scarcely half the height they may be expected to reach; harsh, rigid, and very much branched, with the dranches opposite, straight, copiously leafy: at the internodes, or setting on of the leaves and branchlets, are two to four stout, sharp-pointed, large, smooth, brown warts. Leaves invariably opposite, on very short petioles, nearly sessile, spreading, subrotund or subcuneate, ob- tuse or retuse, concave above, glossy, as seen under the lens impresso-punctate ; the margin beset with rather distant, short, spiny teeth, pale beneath, and minutely reticulated ; the areole deep and pubescent. Unméels, rather than corymbs, lateral or more rarely terminal; the rachis from which the short rays spring short and fleshy. Flowers of a rich purple blue ; in other

respects exactly resembling those of Ceanothus verrucosus, figured in our last number, Tab. 4660.

For the opportunity of figuring this truly splendid plant, we are indebted to Mrs. Spode, the lady of Joshua Spode, Esq. Armitage Park, Rugely, Staffordshire, whose gardens and rare exotics are celebrated in the neighbourhood, and are likely to be still more so from the taste and skill displayed by their generous proprietors, and by the zeal and energy of their intelligent head gardener. The Nympheacee, including the Victoria, are there cultivated in great perfection ; but however interesting this latter plant may be, and is, in size and structure, it does not surpass in beauty the present, which was contributed to their aquarium from Chatsworth : and it is this, we presume, which we find mentioned in the leading article of the ‘ Gardeners’ Chronicle,’ above quoted. The writer, after recommending the advantages that might be

of size and robustness of growth over either of its parents; but its most valuable property is its continuing to flower the whole of the season without intermission. The present plant produced its first flower as early as the 12th of April, 1851, and continued to flower till the middle of October, when it was removed with a fine succession of flower-buds still upon the plant to its winter quarters. During this period it often had two expanded flowers and five buds’ in different stages of development. It produces its flowers quite as freely as WV. dentata*. Its beautiful colour (which is not quite so deep as its parent), and its large size, which has often been as much as eight inches in diameter, together with its fine leaves, which are seldom less than thirteen to seventeen inches across, render it one of the best Mympheas in cultivation.”

Our living plant at Kew, the possession of which we owe to Mrs. Spode, as well as fine cut specimens we have received for figuring from Armitage, and noble fresh samples at this moment lying before us (July 16, 1852) sent by Mr. Davison from Sir W. Molesworth’s tropical aquarium, Pencarron, Cornwall, amply jus- tify all that Sir Joseph Paxton has said above ; and we trust yet to live to see a well-constructed tank, in which the variously- coloured Nelumbia and Nymphee, now known to us, including the majestic WV. gigantea (see our Tab. 2647), lately imported by Messrs. Standish and Noble, shall be suitably grouped.

Mr. Davison observes, that with him Devoniensis grows and flowers most freely, planted in rough turf taken from a pasture and laid in a heap one year previous to its being used, with one- sixth of dried cow’s-dung. The water in the tank in which it grows is kept from 75° to 80°.

* The name NV. dentata is introduced here as if it were one of the parents of N. Devoniensis, rather than N. Lotus, as previously mentioned. N. Totus and _ NV. dentata are very closely allied species, if they be really and truly distinct. _ At our Tab. 4257 I have pointed out in the pale and depressed base of the

We have at length the satisfaction of giving a figure of this noble plant, the first published from flowers produced in the open air in England. The opportunity of doing so 1s afforded me by the kindness of the Right Rev. the Lord Bishop of Exeter, who did me the favour to send me two panicles from his favoured grounds of Bishopstowe, near Torquay. “The blossoms,” his Lordship writes, “are in terminal clusters ; and the odour (which will probably be lost when it reaches you) 1s of a very delicate violet-dike character.” —“ But, after all, the effect to the eye is rather disappointing ; for the blossom precedes the leaves, which are not yet half out.” The fragrance, so far from

being lost on the journey, was rather increased, and the box re-

tained the very agreeable odour some days after the flowers were removed. Unquestionably the absence of leaves, as the Bishop justly observes, is a great deficiency, especially in a plant whose size prevents the blossoms from being closely inspected upon the tree ; yet a cut panicle of these large pale violet-purple blossoms, as large as those of the Foxglove, with a young shoot of tender green leaves, is a very lovely object, to say nothing of the fragrance as a further recommendation. Unfortunately it is only in climates

avGust Isr, 1852.

analogous to the south of Devonshire* where its blossoms can be reasonably looked for. About London we find our strongest and healthiest plants with their terminal shoots (which alone produce flowers) nipped, and more or less killed, by the winter’s cold, or, what is worse, the biting north-east winds of spring. The summer-growth of this tree is almost everywhere, in the middle and south of England at least, remarkable: stout limbs are thrown out ina short time, bearing ample foliage ; but these limbs are soft and succulent, the later shoots incapable of bear- ng a moderate frost. In France, even at Paris, the wood ripens etter.

Although forming a tree (in its native country, Japan, thirty to forty feet high), and bearing flowers like a Bignonia, and with a foliage and habit like Cata/pa, the Paulownia belongs never- theless to the Scrophularia family. Dr. Siebold considers it “ un des plus magnifiques végétaux du Japon;” and partly on this account and partly “parceque la feuille ornée de trois tiges de fleurs a servi d’armes au célébre héros Tarkasma, est encore aujourd’hui fort en honneur en Japon,”—‘ nous avons pris la liberté de nommer Paviownra ce nouveau genre, pour rendre hommage au nom de Son Altesse Impériale et Royale la Princesse héréditaire des Pays Bas.”

In Japan the trunk of the tree attains an elevation of thirty to forty feet. Its growth in Dr. Siebold’s garden has been six to ten feet in one year, and in three years a diameter of four to five inches. The flowers appear in April, and are grouped in large compound panicles, like those of the Horse-chestnut. It appears most abundantly in the southern countries of J apan, flourishing

in the valleys and on the sides of hills exposed to the powerful action of the sun.

ee Who would not wish to see a Botanic Garden established in a climate like that of Bishopstowe ? There, for example, are at this moment flourishing the various Californian species of Ceanothus (as mentioned in another part of this number, Tab. 4664), the blue-flowered ones, no doubt, with their glossy per- ennial foliage, more agreeable to the eye than the Paulownia. A Eucalyptus (supposed to be eight years old) is twenty feet high. Juniperus Bermudiana (the pencil Cedar) thrives well in the open lawn. The orange-scented Pitio- sporum, eight feet high and ten feet across, flowered at Christmas, and again more

profusely in spring. The undermentioned trees, only two years old, have attained the following size :—

A well-known West Indian shrub, or rather tree, especially common in Jamaica, whence our plant was derived; but it 1s little seen in cultivation, by no means so much as it deserves : for although in its native country it attains a height of fifteen or twenty feet (M‘Fadyen; Sloane says forty feet), yet, cultivated in a pot, in a warm stove, it maintains a shrubby character for a very great number of years, with pretty, evergreen, box-like foliage, bearing copious bright orange pea-shaped flowers m the month of May, yielding a delicious perfume. It abounds in the savannas and dry hills of Jamaica, where Dr. M‘Fadyen says, with its long twiggy branches, it reminds the traveller of the Broom of Europe. The wood is hard and ponderous, of a fine greenish-brown colour, susceptible of a good polish and used

formerly to be imported into Europe: but it is extremely dif- ferent from the true Ebony of commerce, Diospyros Ebenus of Madagascar; and the trunk, rarely exceeding four inches in diameter, can only yield small samples for cabinet-work. ‘“ The slender branches,” says Patrick Browne, “are very tough and flexile, frequently used for riding-switches, and in his days (days happily now gone by) generally kept at all the wharfs about Kingston to scourge the refractory slaves.”

Of the many Indian species of Calanthe now known to us, the flowers of this are decidedly the largest ; some of the pure white flowers (or with only a spot of yellow on the disc of the labellum) measuring two and a half or two and three-quarter inches from tip to tip of the petals. The leaves, too, are broad, and the pseudo-bulbs often much larger than our figure represents them. It flowered at the Messrs. Rollisons’ Tooting Nursery in April, 1852. It seems to have previously flowered with the Messrs. Veitch in 1848, when the large silver medal, the highest ever given in Regent-street, was awarded to it by the Horticul- tural Society. ,

lated, terminated with the remains of the former year’s leaves. Leaves appearing after the flowers, two or more from a young pseudo-bulb, large, a foot to a foot and a half long, four to five inches broad, broad-lanceolate, much acuminated, membrana- ceous, striated. Scape radical, from the base of an old pseudo- bulb, a foot or more long, villous with patent hairs, bearing a few sheathing glabrous scales. Spike lax, bearing six or mote, large, very white flowers. Sepals and petals much spreading, broad-lanceolate, very acute, nearly uniform. Zip also very patent, the base united to the whole length of the column, suborbicular in outline, but deeply three-cleft ; the side /odes oblong, obtuse, waved; the middle /obe broad-cuneate, again divided into two divaricating obtuse /odes: the disc of the labellum is orange- yellow and striated: the spur shorter than the lip, filiform, in- flexed. Anther sunk into the apex of the column, hemispherical, with a broad blunt projecting beak. Pollen-masses eight, co- hering in fours with a filiform, bipartite sta// or gland.

Of this really beautiful hardy plant, cultivated in our gardens so early as 1683, no good figure has hitherto been given. It is a littoral plant of South Europe. Its northern limit seems to be Nantes, and thence it extends itself along the coasts of Spain and Portugal, and the western shores of the Mediterranean. Desfontaines detected it in Barbary, and Broussonet in Morocco. In our country it is best treated as an annual. In warmer climes it is at least biennial, the lower part of the stems becomes quite woody, and then the branches are more. strictly erect, and more

numerous from one point than our figure represents them. Mainly on this account, as it would appear, Boissier makes two varieties, his var. Broussonetii, and var. alyssoides. Seeds were sent to us by Mr. Wellwitzsch from Portugal, and the plants bear their lovely flowers during the summer and autumn.

Descr. Our annual plants (and they would hardly survive a winter in our climate) have erect, but flexuose, branching sfems, scarcely a foot high, terete, hoary, as is the whole plant, petals and stamens excepted, with short stellated hairs. Leaves lanceolate or linear-lanceolate or more frequently subspathulate, tapering a good deal at the base, but sessile, sometimes sinuate-dentate, more usually quite entire. Yowers large for the size of the plant, im lax, terminal, many-flowered racemes. Pedicels at first very short, at length about equal in length to the calyx. Calyx narrow, oblong. Sepals linear, obtuse, quite erect, two of them a little gibbous at the base. Petals obcordate, clawed, delicate, bright, pink-purple (not albido-flavi, as De Candolle describes them), the lamina spreading horizontally (not veiny, like Malcolmia maritima, Bot. Mag. t. 166). Stamens six: the four longer nearly equalling the pistil; two shorter rather longer than the germen. Germen cylindrical, downy. Style short. Stigmas two, long, linear, glandular within, and at the margin and apex, and united for the whole length of their faces into one, more or less bifid at the point. Si/igua two or two and a half inches long, slender, terete (not torulose), flexuose, erecto-patent, terminated by the style and now sharp, withered stigma.

The discovery of this Prince of Lilies, we owe, as we do so much of Indian and especially northern Indian botanical novelty, .to Dr. Wallich*, who detected it in moist shady places on Sheo- pore in Nepal. ‘This majestic Lily,” writes Dr. Wallich, “ srows sometimes to a size which is quite astonishing ; a fruit- bearing specimen of the whole plant, which is destined for the Museum of the Hon. East India Company, measures full ten feet ~ from the base of the stem to its apex. The flowers are propor- tionably large and delightfully fragrant, not unlike those of the common white Lily.” Nor does it degenerate in cultivation ; witness the specimen from which our drawing was made, a por- tion of which was obligingly communicated to us through Dr. Balfour, by the Messrs. Cunningham, Comely Bank Nursery, Edinburgh, in July, 1852, accompanied by a full-length repre- sentation made on the spot. ‘These showed the flowering plant to have attained a height of ten feet in one season ; the flower portion occupying twenty inches. Such a raceme of flowers, accompanied by leaves measuring ten to twelve inches long and eight inches broad, must have afforded a striking spectacle, and which has only yet been witnessed at the nur- sery just mentioned, where the plant was raised from seeds

sent by Major Madden some five or six years ago; but it has only now for the first time blossomed in Europe. The bulb was treated in the ordinary way without heat. Baron Hiigel found the plant in the Peer Punjil pass of the Himalaya, leading into Kashmeer; and we believe that Drs. Thomson and Hooker met with it abundantly in other portions of that vast range of hills. The remainder of our account shall be taken from Dr. Balfour’s notes, chiefly drawn up from the living plant at Comely Bank.

“Major Madden says the Lilium giganteum is common in the damp thick forests of the Himalaya, the provinces of Ka- maon, Gurwhal, and Busehur, in all of which he has frequently met with it. It grows in rich black mould, the bulb close to the surface, at from 7500 to 9000 feet above the level of the sea, where it is covered with snow from November to April, or there- abouts. The hollow stems are commonly from six to nine feet high, and are used for musical pipes. he fruit ripens in No- vember and December.

“Descr. Stem straight, cylindrical, smooth, gradually atte- nuated to the apex, nearly ten feet high, five and a half inches in circumference at the base, green with a reddish-purple hue at the upper part.. Leaves alternate, scattered, the internodes varying in length, petiolate, broadly ovate, cordate, acuminate, shining dark green above, paler below, venation reticulated, having an, evident midrib, with the veins coming off from it ending in an intra-marginal vein ; lower leaves with long petioles, very large, ten to twelve inches long, eight inches broad, becoming gradually smaller in ascending; upper leaves small, sessile, ovate, acute- Petioles of lower leaves twelve to fourteen inches long, thick, broad and somewhat sheathing at the base, lower surface convex, upper with a deep and broad furrow ; petioles of upper leaves short. Bracts ovate, acute, caducous, leaving a semilunar scar. Powers white, with purple sheaths, greenish below, infundibuliform-cam- panulate, inclined downwards, twelve on the raceme, fragrant ; tube greenish, two inches in circumference at the base, gradually dilating upwards ; limb slightly revolute ; leaves of the perianth oblong-spathulate, three outer with slight purple streaks inside, three inner rather broader, with a deep purple tinge on the inside, and with a prominent ridge on the outside, sulcated on either side, and two elevated ridges on the inner surface separated by a shal- low groove. Peduncles round, thick, from a quarter to one inch in length, greenish-purple. Sfamens and pistil included. Stamens six, three outer longer ; anther versatile; pollen yellow.

In July of the present year (1852) we had the pleasure to re- ceive fine flowering specimens of this Zacsonia from Mr. Hugh Low, of the Clapton Nursery, to whom the plant had been sent, from Trinidad, by Henry Rye, Esq., under the appropriate but MS. name of Passiflora diversifolia. It is however unques- tionably the Passiflora sanguinea of Sir J. E. Smith, in Rees 's Cyclopedia, above quoted, and only by that description known to De Candolle, who was induced to refer the species, in its present genus, to the section Hutacsonia ; and thus, apart from three sup- posed West Indian species, 7. guadriglandulosa, T. quadridentata, and 7: pubescens, placed in the section “Distephanz dubiz. These three, though very briefly, characterized by De Candolle, one from Guiana (whence we have also received this species), and the two others from the “ West Indies,” derived from the Banksian Herbarium, and very probably from Trinidad, appear to us to be referable to one and the same plant. ‘The very va-

riable nature of the leaves on the same or on different individuals will easily account for their being supposed distinct. We have copious specimens in our Herbarium, gathered in Trinidad by the late Mr. Lockhart. Sir James Smith’s specimens were re- ceived from Smeathmann.

A climber, with terete dranches, and Jeaves which are extremely variable on the same or on different plants, sometimes ovate or oblongo-ovate, acute, simple; sometimes cordate and deeply three-lobed, with the lobes ovate, acute; the margins everywhere remarkable for being more or less sinuous, and cut into large but unequal teeth, penninerved, the underside strongly reticulated with prominent nerves, sometimes downy and pale green, whereas the upper side is generally glabrous and dark green. Pe/ioles about half an inch long, glandular at the base, and there are sometimes glands in the sinuosities of the leaves. Peduncle solitary, single-flowered, longer than the petiole, fur- nished below the apex with a small three-leaved downy éavolucre : ' the leaflets from a broad base, linear-subulate, serrated, erect, each having one or two large orbicular glands on either side at the base, and a gland within the axil. Hower large: sepals five, oblong-linear, acuminate, spreading, having a long soft subulate awn a little below the apex ; externally the sepals are greenish rose-colour, within uniform rose-red : they all unite below so as to form a five-furrowed, rather short, greenish tube, very obtuse at the base. Petals five, as long, and of the same shape, as the sepals, equally spreading and deep rose-red on both sides. Crown or nectary double, short: inner consisting of a white membrane, with many subulate, erect, red rays; outer of a circular row of humerous erect filaments, white, banded and tipped with red: some lesser filaments, and very short, are found between the outer and inner corona. Column three or four times as long as the crown, greenish, spotted with red, as are the short recurved

NavTILocALyx hastatus. Hort.

This very remarkable plant was received at the Royal Gardens of Kew, from Mr. Linden, under the name of Nautilocalye has- fatus. Such a name we can find nowhere published, and we cannot but consider it inaccurate, inasmuch as there is nothing about the calyx in any way representing a Nautilus ; and, if meant to refer to the two outer bracteas (and not the calyx), we venture to consider they represent a bivalve shell, some kind of Pecten or Venus, vather than a Nautilus. We only adopt the opinion of Mr. Bentham in considering the genus to which the plant belongs not distinct from his Centrosolenia (see our two species, figured at Tab. 4552 and 4611 of the present Magazine). From those, and indeed from every known species, the present is abundantly distinguished by the large size of the leaves, and, in proportion, the still larger size and peculiar form of the external bracteas, which enclose the axillary clusters of leaves. It is a stove- plant, a free flowerer, and its blossoms continue to appear through the entire summer months. We have no information respecting its native country ; probably it is New Grenada or Venezuela.

Duscr. Stem’ stout, herbaceous, erect, simple, two feet ligh, the upper part clothed, as is most of the younger portion of the plant, with deciduous silky down. Leaves opposite, very large (almost a foot long), nearly equal, ovate, acummate, coarsely

serrated, penninerved, beneath reticulated and the nerves pro- minent, below tapering very much, the base of the two opposite leaves unite and surround the stem, or, in other words, the leaves are decurrent upon the petiole so as to form a very broad wing to the extremely thickened rachis. In the axils of the leaves there appears on a short peduncle a pair of very large, vertical, nearly orbicular, concave, sharply, almost cuspidately acuminated, purple-green, reticulated dracteas, two inches across, at. first closed like the two valves of a shell, then partially expanded for the emission of the several flowers, within which they ex- pand, in succession, and are themselves bracteated with ovate or lanceolate acuminated and serrated dracteoles. Each flower, when fully open, is nearly as long as the external bracteas, and shortly pedicellate. Calyx a little shorter than the tube of the corolla, white below, red-purple above, and reticulated with white, deeply cut into five segments, of which four are lan- ceolate, serrated, finely acuminated, the fifth free to the very base, and bent down, as it were, below, by the prolongation of the spur, and this is subulate, very narrow. Corolla large, white, the tube dilated upwards, below on one side extended into a short, blunt sur; the limb spreading, of five nearly equal, entire, rounded segments or lobes. Stamens four, perfect, in- cluded within the tube of the corolla; filaments subulate, di- dynamous, curved over the pistil. Anther subglobose. Ovary ovate, slightly pubescent, with a large fleshy hypogynous gland

on one side. Style thickened, a little curved. Stigma slightly dilated.

Received at the Royal Gardens of Kew from seeds sent from Veraguas by Mr. Seemann. I have failed in finding the de- scription of any species that will tally with it. Much of the character, indeed, of B. peltata, Haskrl., as given in the fifth volume of Walpers’ Repertorium, p. 7 66, well corresponds with this; but that is placed in a group called “ Repentes, 1s said to be “caulescent,”’ and is a Java plant. Further, the same species is described in the second volume of the Repertorum, p- 210, as having the leaves tomentose: whereas our plant is not caulescent, nor creeping, and has glabrous foliage. It is indeed a most lovely species, with singularly shaped, very thick, concave and peltate leaves, deep blood-colour beneath, and the copious petioles, peduncles, and flowers of a full rose-red. It flowers readily in the stove during the summer months.

quite glabrous, dark green above, with a pale spot at the inser- tion of the petiole, from which a few indistinct nerves radiate, deep blood-red beneath, with the nerves slightly prominent.

A very remarkable-looking plant, native of Brazil, sent to us by Messrs. Rollison, Tooting, and by Mr. Henderson, St. John’s Wood, under the name of Goethea cauliflora of Nees von Esen- beck. That it belongs to the genus Goethea (so named in honour of the great German poet, Goethe), as defined by Nees von Esen- beck and Martius, is clear; and it is generally known that this genus is referred by Endlicher and others to Pavonia, in true Malvacee, and not to Byttneriacee, where De Candolle has placed Goethea, on account of the supposed bilocular structure of the cells of the anthers. Whether a distinct genus or not, it 1s quite certain that the present plant can neither be the G. cauliflora of Nees and Martius, nor his @. semperflorens : the latter has scat- tered terminal long-pedicelled flowers, and six bracts to the in- voluere ; while the former has oblong entire leaves, and drooping (quite pendent) axillary or lateral flowers. Our plant, it will be seen, has the leaves broad-ovate and sinuato-dentate, and the: flowers invariably erect from the axils of the leaves. The flowers are very inconspicuous, and quite concealed by the involucre,

whose beautiful red-vemned bracts, looking like a calyx, persist long after the blossoms have passed.

Drscr. The plant before us is one and a half foot high, at pre- sent unbranched, woody below, more herbaceous above. Leaves alternate, large, petiolate, ovate, often broadly so, acuminate, pen- ninerved (with three principal nerves from near the base), the upper half sinuato-dentate at the margin. Peduncles short, ag- gregated in the axils of the leaves (and often remaining after the leaves are fallen, above the scars), scarcely half an inch long. Involucre of four, erect, pale yellowish-white, cordate dracteas, striated and veined with red, including a single fower, whose stigmas alone are sometimes protruded beyond the involucre. Calyx nearly white, or greenish, cut into five, erecto-connivent, acuminated lobes. Corolla of five, obcordate, veiny, small petals, which are united by their base to the cylindrical tube of the filaments of the anthers, shorter than the calyx. Anthers reniform, one-celled, exserted beyond the calyx, as is the free portion of the filaments. Ovary subglobose, five-furrowed. Style as long as the tube of the anthers, then separating into ten branches, each bearing a capitate stigma.

Messrs. Veitch of Exeter received this really handsome Bramble from Nepaul, and cultivated it for some time under the name of R. leucodermis, a name it well deserves, from the pure white of the stems of the plant, looking exactly as if they had been white- washed. Closely examined, the cuticle is found covered by an extremely minute, perfectly white, pulverulent substance. The name however of Jeucodermis is given by Mr. Douglas to a North-west American species, and adopted by Messrs. Torrey and Gray in their ‘Flora of North America,’ which species we have been ourselves led to consider a variety of Rubus occiden- falis of Linneus. Our plant is identical with a Nepaulese and Himalayan species in our Herbarium, which we believe to be _the R. biforus of Dr. Buchanan (Hamilton), and probably the

R. pedunculosus of Don. It is quite hardy and ornamental, and

very striking from its tall very white stems, and its copious white flowers produced in May and June, which are succeeded by the good-sized and well-flavoured orange or rather deep amber- coloured fruit in the early autumn. We feel sure that this hand- some and agreeable fruit would be worth cultivating for the table.

Duscr. The stems spring from the ground in clusters or fas- cicles, like our common Raspberry (to which group of Rudus it belongs), but attains a height of ten to twelve feet, erect, branched with many small slender side-branches, the epidermis everywhere clothed with a very white pulverulent coat (easily removed by passing the hand over it), aculeated ; the aculei scattered, uniform in shape, all from a broad base subulate, decurved ; those of the stem stout and strong, those of the branchlets small and slender. Leaves extremely variable, even on the same plant, always green and subglabrous, downy and white beneath, in shape sometimes cordate, unequally and irregularly lobed, at other times regu- larly three-lobed ; sometimes compound and ternate, the lateral lobes generally narrow, ovate, and sessile, intermediate or ter- minal one broader and larger and petiolulate, sometimes, but more rarely, pinnated with five leaflets, all inciso-serrate, pin- nately and reticulately veined. Peduacles about two inches long, sometimes binate, more generally fascicled at the ends of the small lateral almost herbaceous branchlets, drooping, simple and bearing one, or branched and bearing two or three (rarely more) white flowers. Calyz subhemispherical, cut into five broad acu- minated downy lobes. Petals obcordate, spreading, close-placed, and imbricating with their edges. Stamens small, forming a dense ring round the ovaries. Fruit as large as a Raspberry, but deep amber-colour ; when young, almost enclosed in the erect lobes of the persistent calyx ; afterwards, the calyx spreads, and the globose fruit is wholly exposed to view.

Fortune's Dovusie YELLOW,

or Wang-jang-ve Ross.

Fortune’s Double Yellow Rose. Lindl. in Journ. of Hort. Soc. Lond. 1851. v. 6. p. 52.

If it is desirable to give a botanical specific name to a hybrid plant at all, it can only be done, with any kind of propriety, when we are acquainted with the double origin of the plant in question, viz. both parents. Of the pedigree of the Rose here figured we know nothing, save that it comes from China; and, as Dr. Lindley has observed, it is fruitless to inquire. As an ornamental Rose for the garden, we should have thought there could have been but one opinion among those who have seen the flowering plant (the delicacy of the petals cannot be imitated by art), and ¢hat is entirely in its favour. But it has been spoken of unfavourably by some; and this has been accounted for by Messrs. Standish and Noble, to whom we are indebted for the specimens here published, and whose remarks, together with those of Mr. For- tune, who introduced the plant from China to our gardens, shall occupy the remainder of our space. UES

« Seldom,” write Messrs. Standish and Noble, in June of the present year, “has a really beautiful flower remained so long comparatively unknown as this. Few persons have seen a blos- som; and those who have not, believe it to be worthless. In fact there exists a deeply rooted prejudice against the plant, caused, no doubt, by the very unfavourable report circulated when it bloomed the first time in this country. Yet nothing can be more beautiful as a flower, nor can anything exceed it in delicacy of tint. Imagine a gamboge-yellow ground, over which is thrown a tint of crimson lake, and you obtain an idea of its: colour. The centre petals have generally a predominance of lake, and the outer ones are more strongly marked ; but there is a beautiful clearness about them, which can only be appreciated by examining a flower. Apart from the prejudice which exists against the plant, many persons have spoken derogatively ol

it, from having failed to cultivate it successfully ; their plants producing but few flowers, and. those indifferent both in size and colour. ‘This has arisen from an improper mode of treatment. If pruned in the manner usually adopted for ordinary standard Roses, no flowers will be obtained, as they are produced from the wood of the preceding year, in the same manner as those of the Persian Yellow and Banksian Roses. Therefore, whether grown as a standard or trained to a wall, the shoots should only be thinned,—to shorten them is to destroy the flowers. We have at the time of writing this (June 28) some standards, from three to four feet through the heads, covered with blossoms ; and more beautiful objects can scarcely be imagined. We wish all who are prejudiced against the plant could see them. Again, it has been said to be tender; but we have never seen it injured in the least, even during the most severe weather. It is one of Ao most rapid-growing roses, and well adapted for a wall or pillar.”

Mr. Fortune tells us, “'The Rose you inquire about is well known to me, and was discovered in the garden of a rich Man- darin at Ningpo. It completely covered an old wall in the garden, and was in full bloom at the time of my visit: masses of glowing yellowish and salmon-coloured flowers hung down in the greatest profusion, and produced a most striking effect. It is called by the Chinese the Wang-jang-ve, or Yellow Rose. They vary, however, a good deal in colour; a circumstance which, in my opinion, adds not a little to the beauty and character of the plant. TI fancy it is quite distinct from any other known variety, and certainly different from any China kind. It is ad- mirably adapted for covering walls; and if planted in rich soil, and allowed to grow to its full size, nothing can produce a finer effect in our gardens. It was sent home to the Horticul- tural Society in 1845, and noticed by me in the Journal of the Society, vol. i. p. 218, and again in my ‘Journey to the Tea Countries,’ p. 318. No doubt the Wang-jang-ve, now that it has been properly treated by Messrs. Standish and Noble, will soon take its place as a favourite amongst our climbing roses.”

A native of Java, long cultivated in the stove of the Royal Gardens of Kew, as an unknown plant, with the habit of Zer- minalia. Tn the summer of 1852 the handsome flowers ap- peared. It is clearly the plant “collected by the late Sir G. L. Staunton, Bart., who discovered it in his voyage to China, but in what country is not mentioned,” and taken up by Sir James Smith as Hleocarpus grandiflora, in Rees’ Cyclopedia, where the author has faithfully described the anthers as those of a Monocera. This name has been strangely overlooked, as far as I can find, by all succeeding authors; Blume, considering

the plant a new species, described it under the name of L/@o-

carpus lanceolata. We possess Herbarium specimens from Count Hoffmansegg, from Mr. Thomas Lobb (n. 19), and from Pro- fessor De Vriese, all gathered in Java, yet Blume only speaks of it there as “in hortis frequenter colitur.”” These specimens however show that the plants vary in the leaves being crenato- serrated or entire, and in the length of the petiole, from one- fourth of an inch to an inch long. ‘The bright red of the calyx and pedicels, the cream-coloured fringed petals, and large flowers, in conjunction with the evergreen foliage, give it a handsome appearance.

Dzscr. A shrub, with us seven feet high, much branched ; the eaves a good deal clustered at the apices of the branches, from three to nearly six inches long, including the petiole, broad lanceolate, tapering into a footstalk from one-fourth to one-half an inch long, the apex generally obtuse, the margin entire, or usually more or less crenato-serrated or sinuated.

Anther oblong, tapering into a long subulate beak, longer than the anther, the two cells opening at the base of the beak, the opening closed by a small valve.

Matva involucrata. Zorr. et Gr. Fl. N. Am. v. 1. p. 226. Nurraxra involucrata. Nutt. ex Torr. in Am. Lyc. New York, v. 2. p. 172.

Certain Malvaceous plants of North America, with a somewhat peculiar aspect, vacillating in habit between Sida and Maiva, and varying in the presence or absence or deciduous nature of the involucre, were referred by Mr. Nuttall to a new genus, Callirhoe, by Mr. Dick called Nuttailia (see Bot. Mag. t. 2612 and 3287). This genus has been, as it were, by general consent abandoned, the species transferred to Malva, and a new and more firmly established genus given to the distinguished Ame- rican Botanist in Rosacee*. Our present plant would have been a Nuttallia of Dick, and hence was given the name involucrata, to distinguish it from some MVuttallias which were destitute of this organ, a name not very appropriate among true Malve. The plant was first detected in the valley of the Loup Fork of the Platte, by Dr. James, and what is described by Drs. Torrey and Gray as “var. £8, lineariloba, with the segments of the leaves divided into three to five narrowly linear lobes, was — found in Texas by Mr. Drummond. Our present plant, of which

Descr. From a central root several branches, eighteen inches to two feet long, radiate, lymg upon the ground, the extremities assurgent, hairy, as is more or less every part of the plant ; hairs of the stems and branches and petioles and calyces patent. Leaves all on long petioles, especially those from near the root, cordate in outline, deeply 3—-5-fid ; of the upper ones the lobes are subtrifid, the lateral ones on the lower leaves are subpedate ; the lowest, and especially the radical ones, are multifid, the segments broad linear or linear-lanceolate, acute and submucronulate with a soft point. Peduncles longer than the leaves, solitary, erect, numerous, bearing a single large showy flower. Jnvoluere of three linear- lancolate spreading green leaflets, about two-thirds the length of the calyx. Calyx very hairy, divided nearly to the base into five, lanceolate, acuminate, spreading sepals. Petals five, broad- cuneate, quite truncated at the apex, and erose, longer than the calyx, deep red-purple, with a cream-coloured large spot at the claw, forming a yellowish-white circle or disc to the flower. Column of stamens rather short, and, as well as the capitate anthers, white. Style as long as the staminal tube: stigmas numerous, filiform-subulate, long, spreading. Carpels (immature) “lunate, pointless.”

Received in a flowering state from the stove of Messrs. Lu- combe, Pince, and Co., in June, 1852. It was sent to them by Mr. Yates, from Para, in Brazil. The flowers are in general structure like those of Sobralia, but of a yellow colour, and with foliage more like that of some Caiéleya, thick and _ leathery. Poeppig and Endlicher have a genus Cyathoglottis (Nov. Gen. et Sp. Plant., ete., p. 55), which they distinguish from Sobralia by very slight characters, adding “ Sodraiie tamen proxime affine

videtur,” and which has yellow or white flowers: but the anther

In a sterile plant sent us, the leaves are more nearly equal and more oblong. The flower is large, terminal, sessile, curved, of a uniform pale sulphur-coloured yellow. Ovary clavate, sessile, rising a little above the sheath of the upper or bracteal leaf. Sepals four inches long, erecto- connivent, acuminate, united for some little way above their base.

Column clavate, curved, about two-thirds the length of the flower, yellow, deeper-coloured and plain in front ; the apex obscurely trifid, the lobes, especially the latter ones, short, obtuse; the anther-case hemispherical,

A very beautiful new Begonia, cultivated by Mr. Nuttall in his stove at Rainhill, near Preston, Lincolnshire, where it was raised from roots sent in 1850, from Boutan, by his nephew, Mr. Booth. It is remarkable for the large, full, almost golden- yellow flowers, tinged with red at the back, which contrast well |

A very fine new and very distinct species of Hoya, first de- tected in Java by Blume and since by Mr. Thomas Lobb, and | sent by him to his employer Mr. Veitch, in whose stove at — Exeter it has grown very vigorously and yielded its very hand- some flowers during a great part of the summer and autumn. © Some of the leaves measure a foot in length: our coloured figure is taken from a portion of the plant yielding smaller foliage; but these leaves are remarkable no less for their great size than they are for their firmness and thickness, and the very indistinct remote pinnated nerves, scarcely seen except when the leaf is held between the eye and the light, or when the leaves are dried for the herbarium; then the shrinking of the parenchyma brings the veins more distinctly into view, and — shows them to be pinnated, anastomosing, and slender. The petioles and costa beneath are peculiarly thick. ‘The upper side of the corolla, disc excepted, is downy, or between silky and velvety, and of a pale yellowish buff-colour, but five stains or spots are seen radiating from the centre towards the sinuses, which are always wet and clammy, which clamminess appears to be due to a flow of honey from beneath each of the leaves of the crown or nectary, and give a rich brown tone of colour to the whole umbel of flowers.

Of this eminently handsome genus (He/iconia), a genus with the habit of Strelitzia, eleven species are enumerated by Romer and Schultes ; seven more are given in Walpers’ ‘ Annales,’ vol. 1. p. 811, and all are, we believe, indigenous to South America. Amongst all those, be they well-defined species or otherwise, our present plant is readily distinguished by the white pul- verulent substance of the underside of the foliage, and by the small flowers in comparison of the large rich scarlet bracts. A scarcely less handsome species is given at our Tab. 4475, our Heliconia angustifolia (from Brazil), with. shorter, paler-coloured, and more numerous sheathing bracts, larger flowers, and very long narrow leaves. The exact native country of the present 1s not known. It appears to have been introduced to our stoves some twenty years ago by the late Sir Abraham Hume, from whose hothouse at Wormleybury the figure m the ‘ Botanical Register’ was made. We possess a portion of a leaf of a Heli- conia from Dominica similarly white and pulverulent beneath, gathered there by our friend Dr. Imray, but whether identical with ours it is impossible to say without further materials, which we hope soon to receive. Our drawing was taken from a fine plant, that blossomed at Kew in June, 1852.

From the sheathing base of an upper leaf the zxfores- cence appears, consisting of a stout zigzag rachis clothed with the sheathing bases of three (or four, including the longer lowermost flowerless one) long, stout, subulate, conduplicate, very acuminated bracts or spathas, sheathing at the base. From the axils of these a cluster of rather small, whitish-green flowers appear, not much protruded beyond the sheathing portion of the spatha. Their structure is as in the rest of the genus. The sixth very diminu- tive sepal is very small, a mere oblong scale, mucronate at the point.

It is a misfortune with many of the Dendrodia whose stems bear the flowers, solitary (as here) or two or three from the same point opposite to that of the insertion of the leaf, that when the blossoms are in perfection the foliage has fallen. This is the case with the species now before us. The old long jointed stem here shown has a fair sprinkling of flowers, but there are no leaves, save on a young stem that is forming at the base of the old ones, and which, in its turn, is to shed its leaves and then throw out.blossoms. Nor does our species boast of rich colours in the sepals and petals. Their general or ground colour is white, and of that dead and chalky kind which sug- gested to Dr. Lindley the specific name of cre¢acewm. Our plant was sent to us from Assam in 1851 ; its flowering (in June, 1852) confirms the correctness of Dr. Lindley’s suspicion, that the flowers are always solitary, not in twos or threes, as is charac- teristic of the section Hudendrobium (Grastidium, Blume). Mr. Griffith found the same species in Mergui and the Khasya hills, and Mr. Thomas Lobb sent it to the excellent Nursery of Messrs. Veitch, Exeter.

This, as well as the purple-flowered variety of it, were im- ported by Mr. Bridges from Bolivia (not Chili, as stated by Mr. Smith, in Bot. Mag. under Tab. 4521). The latter is already figured in the plate just cited, and we scarcely know which is the more striking of the two. The purple-flowered variety has the ad- vantage in the colour of the flower, but the present kind produces the largest blossoms; the petals are broader in proportion to their length, a cream-white gradually passing into the greenish- purple of the outer sepals. The spines in the present variety are more slender, less curved, of a paler colour, but tipped with a darker brown. In other respects the two plants correspond, and a full description under Tab. 4521 will equally suffice for the present. Its flowering season 1s July.

Echinopsis, as we there observed, is a genus recently sepa- rated from Echinocactus by the Prince de Salm-Dyck, in which twenty species are included in the recently published ‘ Cactes in Horto Dyckensi cult,’ etc., and these are divided into two principal but very unequal groups: “1, TuBERCULAT# : tuberculis

While the recent labours of Dr. Wight on the Vacciniaceous plants of India have induced him to refer all known to him (including the genera Agapetes, Ceratostemma, and Thibaudia of authors) to the true Vaccinium, Dr. Klotzsch’s investiga- tions of the extire family have led him to the opinion that the genera required to be multiplied, so that we find in the ‘Linnea,’ vol. xxiv. (for 1851), no less than fourteen new genera added, and the previously existing ones thus increased — to twenty-eight! According to Dr. Klotzsch’s views, our pre- sent plant, together with our V. Rollisone (Tab. 4612), would, we presume, constitute another new genus, for in its truncated anther-cells (not ending in long tubes) it seems to differ from all his genera, while, according to Dr. Wight’s views and my own, this would be a character of minor importance, seeing how much in habit and all other characters the species accords with Vacci- nium in its ordinary acceptance. Wherever this is placed it must be associated with V. Rollisoni, and it is a native of the same country, having been equally sent from Java to Messrs. Rollison’s Tooting Nursery, by their collector, Mr. Henshall. Than that, however, it is a far more lovely species, with much larger evergreen leaves, more numerous and larger flowers, and the young branches, and the petioles and even the midribs and

- Descr. The plant before us is nearly a foot and a half high, a compact handsome shrub; the young éranches quite red, and the young foliage stained with red. Leaves alternate, evergreen, coriaceous, glossy, one and three-quarters to two inches long, ovate, rather obtuse, quite entire. Petioles very short, thick, red. acemes clustered (two to four together), terminal, two and a half to three inches long, sessile, or nearly so. lowers numerous, moderately large, secund, drooping (all pointing down- wards). achis rather stout, green, bearing on the upper side several large, foliaceous, oblong, green dracteas, much longer than the flowers. Pedicels curved downwards, shorter than the flowers, red. Calyx green, glabrous, ¢ude (incorporated with the ovary) hemispherical, lobes of the /imé rather large, ovate. Corolla urceolate, quite glabrous, deep coral-red ; the limd of five, small, reflexed segments. Stamens ten, included ; filaments _ subulate, free, hairy. Anther oblong, muticous, the two cells truncated (not prolonged into tubes), opening by nearly trans- verse pores as wide as the cells (not contracted). Epigynous dise very large and hairy. Style columnar, as long as the co-: oe hairy in its lower half. Stigma peltate, obscurely five- obed.
