My pear Mk. Panrisu,
Pray accept the dedication of the 96th Volume of the _ “Borantcat Magazine” in the spirit which has prompted it: a desire, namely, to record my sense of the value of your Botanical discoveries, especially of Orchids, in the Eastern Peninsula of India; and of your many contributions to the collections at Kew, of whose beauty and interest the plates of the “ BorantcaL Macaztne” afford
abundant evidence.
Believe me ever,
Very sincerely yours, JOS. D. HOOKER.

For our first knowledge of this most magnificent plant we were indebted to an article and drawing contributed to Regel’s Gartenflora, by M. E. Ortgies, of the Ziirich Botanic Garden ; where, however, the specimen described and figured is literally not one-third the size of that here given, and very inferior in beauty; the flowers being in the German plate only two and a half inches in diameter, and of a pure white, whilst ours are seven inches in diameter, tinged with faint lilac and streaked with blood-red at the base. This in- crease of size cannot, as might be suspected, be due to, or ac-

companied by, a loss of fertility, for M. Ortgies describes the ray flowers as neuter, whereas those of our specimens have , fully-formed achenes, and short 2-fid styles sunk in the corolla tube. Bie
Beyond its being a native of Mexico, nothing is known of the locality or conditions in which it grows wild. Its tubers were sent from that country to the Ziirich Garden in 1862, and being planted out the stems attained a height of seven feet; these formed buds in October, and on removal to a conservatory the plants bloomed imperfectly. More recently, under good culture, D. imperialis attains a height of twelve to eighteen feet, forming a knotted, erect, straight trunk, naked below, and bearing above a pyramid of foliage and flowers. Flower- ing at so late a season, when protection is necessary, there are few establishments that can afford to grow and bloom so gigantic a plant, in its natural state, but Messrs. Salters, of Versailles Nurseries, Hammersmith, having successfully grafted a plant on the root of a dwarf Dadlia, believe, that by this means not only may plants of convenient size be ob- tained, but that it may be induced to flower earlier, and thus become an outdoor plant in this climate. Mr. Fitch informs me that, Mr. Salter’s plants form a pyramid of six to eight feet high from the ground, and bloom luxuriantly—/. D. H.

A very curious little plant, discovered on the western slopes of the Neilgherrie Mountains, by Dr. Wight, and of which seeds were sent last year to the Royal Gardens, by Major Beddome, Conservator of Madras Forests, which flowered in October of the present year. The genus was named Jerdonia, in honour of the eminent ornithologist, Surgeon-Major T. C. Jerdon, F.L.S., of the Indian army ; it is a stove plant, inte- resting ina horticultural point of view, from its pretty foliage and numerous pale lilac flowers, streaked with blood-red. Botanically it differs remarkably from its congeners in the curious dilated filaments and placentation. I have seen young capsules only, and with immature seeds, these are in- serted on parietal placentas, that do not project far into the axis of the ovary like those of other Didymocarpee. Dr. Wight states that it flowers in March and April, but his dried flowering specimens were gathered in September and October, at which time the new plants also flowered.

In some parts of America and the West Indies this is. known as one of the most beautiful ornamental climbers, rivalling Bougainvillea in the abundance and colour of its blossoms, and yet, strange to say, it has been only of late introduced into Europe. It is a native of Mexico, and we have also specimens from New California, Guatemala, Jamaica, and New Grenada, but no doubt it is only cultivated in some or all of these localities. The plant ‘here figured was raised from seed sent from Honolulu, in the Sandwich Islands, by our excellent correspondent, Dr. Hillebrand, which flowered in October of the present year.

This, the plant which produces the fruit long and well known in commerce as a principal ingredient in West Indian pickles, is much less well known than might be supposed, and its history even at the present time is obscure. Though a re- puted native of the Antilles, it is known there, I believe, in cultivation only, and being the only species of the large genus to which it belongs, which has hitherto been regarded as a native of the New World, its claims to being really indigenous are, as Monsieur Naudin hints, very suspicious. For my own

part, after a careful study of many African species of Cucumis, I am strongly disposed to regard C. Anguria as a cultivated annual state of some one of them, and originally brought by the Negroes from Africa, though so altered by cultivation that it may not be possible to say of which. It clearly belongs to the group including the bitter perennial C. pro- phetarum, Li., which inhabits the drier parts of Africa and Arabia, and is conspicuous for its scabridity and its ashy white hispid pubescence ; but which in moister parts of Africa is represented by the perennial C. Figarii, which is green, and of which the foliage and fruit are very similar indeed to those of C. Anguria; all these lave ovoid berries covered with soft spines and striped with white, and their floral characters are identical.
The specimen here drawn flowered at the Horticultural Society's Garden at Chiswick, in August of the present year, and the fruit ripened in November. There is an excellent description of it by Naudin in the Annales des Sciences Na- turelles, where it is stated to be abundantly cultivated in New Grenada, and latterly in Algeria. M. Naudin ably dis- cusses the affinities of C. Anguria, but pronounces against its eesible identity with C. Figarii or C. prophetarum.—

This remarkably beautiful stove-plant was introduced by Mr. Bull, F.LS., from New Granada, and a flowering specimen was presented by him to the Royal Gardens, Kew, in November 1869, from which the accompanying drawing was made. It appears to flower very freely, and whether for the number and delicate tints of the flowers, or the brilliancy of the green upper- and purple under-surface of the leaves

There is a very similar, and probably identical plant in the Hookerian Herbarium, collected by Lechler in Peru, and also in woods about Monterico, at an elevation of three to four thousand feet, by Pearce, who describes the leaves as fleshy, subacid, and astringent. Lechler’s plant is labelled Monolena Sprucei, by Triana, but that name being unpublished, T have adopted that of primuleflora, which has been already applied to it.

It is also a native of the Fiji and Samoan groups. It was introduced into this country by the late James Backhouse, who collected it on the banks of the Brisbane, and who sent flowering specimens to Kew in 1863. The specimen from which the accompanying drawing was made, was presented to the Royal Gardens by George Macleay, Esq., in 1864. It flowers annually in the month of October, and diffuses a rich honeysuckle-like scent.

The very beautiful plant here figured is a native of the forests of Pegu and Martaban, where it was discovered by a Mr. F. Carey, probably a connexion of the eminent Indian Botanical Missionary, the Rev. W. Carey, who took charge of the Calcutta Botanic Garden during Dr. Roxburgh’s illness and absence, and who, in 1831, edited Roxburgh’s “ Flora Indica,” in which this species is first described. In that work Roxburgh states that Curcuma petiolata was sent by Mr. F. Carey to the Calcutta Botanic Gardens, where it flowered in August. Our specimens were transmitted from Moolmayne by our excellent correspondent, the Rev. C. Parish, and flowered in the Royal Gardens in September, 1869. As a species it is closely related to the Turmeric (C. longa) and to the beautiful C. Australasica (Tab. Nost. 5620), which however, has leaves narrowed at the base, a longer spike, and the flowers are not

Spike five to six inches long, on a ter- minal, short, stout peduncle, broader upwards, two inches diameter across the bracts below, three to three and a half inches across the uppermost bracts, which form a rather de- pressed head. Bracts about twenty to thirty, connate for about half their length, forming deep pouches which wholly include the flowers, green with recurved rose-pink | margins ; lower reniform, one to one and a quarter inches in diameter, with narrow recurved rounded margins; free portions of the uppermost produced into a horizontal, ovate, subacute limb, of a deeper and brighter rose-purple. Flowers pale yellow. Ovary pubescent. Calyx-tube shorter than the corolla-tube, with three blunt lobes. Corolla-tube cylindric below, campanulate above ; three outer lobes broadly ovate, concave, obtuse ; two lateral inner lobes rather longer than the outer, rounded at the tips.

This very elegant new species of the interesting Himalayan and Chinese genus Ankyanthus, was introduced from Japan by Messrs. Standish ; by whom a living plant was presented to the Royal Gardens, from which the accompanying figure was made. It was discovered in 1859, by Sir Rutherford Alcock, and communicated by him to Sir W. Hooker’s Herbarium from the neighbourhood of Nagasaki. It flowers in February, before the leaves are fully developed, but ac- quires its greatest beauty in autumn, when its foliage turns of a brilliant golden orange, diversified with redder spots.
Though hitherto only cultivated in the Temperate House at Kew, #. Japonicus is probably quite hardy, and if so, will

prove a most attractive ornament to the shrubbery. Asa species it is more nearly allied to the Sikkim Z. Himalaicus, both in the foliage and colour of the flowers, than to the original ZL. guingueflorus of China, with which, however, it agrees in its erect capsule; it differs from both in the globose corolla with a very contracted mouth, and in the five large sac-like protuberances at its base.
Duscr. A slender shrub; branches whorled, covered with brown bark, stiff, spreading. Leaves crowded at the ends of the branchlets, one and a half to two inches long, shortly pe- tioled, elliptic ovate or obovate, acute, serrulate, deciduous. Bracts numerous, whorled, obovate-oblong, yellow-green, one quarter to half an inch long. lowers numerous, drooping ; pedicels two-thirds of an inch long, quite glabrous. Calyx of five small ovate subulate lobes. Corolla one-third of an inch in diameter, pure white, globose, intruded at the base, where there are five deep saccate projections; mouth much contracted ; lobes small, broad, revolute.

The specimen here figured flowers in the cooler wing of the Palm House of the Royal Gardens, in November, and has been there for some considerable period, but unfortunately all record of its origin and sender’s name is lost, and it is only through the description in De Candolle’s Prodromus that it has been identified, there being no speci- men of it in the Kew Herbaria. From the temperature at which it flowers under cultivation, it is probably a native of the southern provinces of Brazil or the La Plata district.

This very remarkable plant was discovered by Schlim, in rocky ravines, in the province of Ocafia, in New Granada, at an elevation of 2500 feet above the sea; and was imported by M. Linden, of Brussels, from whom the Royal Gardens received it some years ago. It flowered for the first time at Kew in 1864, and has done so almost annually since, the plant attaining meanwhile a height of about five feet. In the position of the flowers, which are always produced at the

Nost. 4742); it is further a much less attractive plant, wanting the bright red calyces and copious flowers which render the other so ornamental. The position of the flowers upon the midrib of the leaf varies, as they are sometimes produced not far above the petiole (fig. 3), and are often subtended by a second leaf, the upper surface of which faces the back of that from which they: both spring.
Drscr. Quite glabrous. Stem very slender, unbranched. Leaves obovate-lanceolate, ten to eighteen inches long, sub- acute, quite entire, many-nerved ; petiole very short, swollen ‘at the base and top. Flowers one to three, from the back of the midrib of the leaf, shortly peduncled, white. Calyx sub- cylindric, an inch long, green; lobes short, subacute. Petals oblong-ovate, obtuse.

A very beautiful hardy or half-hardy composite, remarkable for the brilliant golden colour of the flowers and the bright- green reticulated foliage, which is snowy-white underneath. It is a native of the Peruvian and Bolivian Andes, and was raised from seed by W. W. Saunders, F.R.8., to whom I am indebted for the specimen here figured. It appears to be thoroughly Alpine, inhabiting rocky places at 14,000 to 18,000 feet elevation; and, like most such plants, is very variable. Three species of the genus are described: P. uniflorus, P. & B.; P. bullatus, Wedd., and P. ovatus, Wedd., (ovalifolius, A. Gray); but I suspect that these are all varieties of one. The present does not exactly accord with any ; but the main, if not only differences, arise from luxuri- ance of growth ; these are the elongated stem, robust habit,

This charming little hardy plant was sent to the Royal Gardens last spring by G. Maw, Esq., F.L.S., from the Rock of Gibraltar, and flowered in the following July. It is a native of walls and stony places in various places in the south of Spain, and is also found in the Canary Islands. We have native specimens from the walls of the convent of Corunna, from the Sierra de Yunguera and Sierra de Gadoz, as well as from St. Roque and Gibraltar.

The subject of the present plate, a native of Brazil, was flowered by W. Wilson Saunders, Esq., F.B.S., of Reigate, in July last, and has been referred, though with some doubt, . to Clavija macrophylla of Miquel. It agrees entirely with that plant in habit and foliage (which forms a magnificent crown of eighteen to twenty leaves in the specimen figured) in the copious racemes (of which there were twenty-six in this specimen), and in the tetramerous flowers with very small calyx and minute subulate bracts half-way up the pedicel ; but it differs from Miquel’s description in the corolla being orange-yellow, instead of white with a scarlet median nerve. I cannot help suspecting, however, that the latter character, apparently taken from notes attached to dried specimens, has originated in a mistake; the flowers being yellow or orange in the closely allied C. ornata and in all

Bow- man, Esq., and was grown ina cool stove in a mixture of loam and peat: it is a slow grower, making a whorl of sixteen to eighteen leaves annually.

This genus was established by Blume, on a mountain plant of the island of Java; but the species here described was subsequently discovered by Wallich’s collectors in the Silhet district of Eastern Bengal, inhabiting damp forests. It also occurs in Assam, where it was detected by Griffith, and extends to the Sikkim Himalaya, whence seeds were sent by Mr. Gammie to the Royal Gardens, Kew, from which the plant here figured was raised. A third species, from the island of Penang, is preserved in the Hookerian Herbarium ; as is a fourth, or possibly a variety of 2. ellip- - ticum, which was discovered by Mr. Parish on the granite mountain of Tinjake, in Martaban; and a fifth discovered by Dr. Thomson and myself in the Silhet jungles.

As Bentham well remarks in his description of this plant, and Masters in his notice of its introduction (Gard. Chron. |.c.), it resembles in its inflorescence a Clerodendron, far more than its allies, the Basil, Coleus, or Mint. It is a very wide- spread Eastern plant from Assam and Birma to the Phi- lippine Islands, and from the Nicobars and Siam to Java, Borneo, and Cape Goole in North-East Australia. It was introduced from the latter locality by Mr. John Veitch, from Whose specimens, which flowered in the Royal Exotic Nur- Series in July of last year, the accompanying drawing was

It has long been known that a second blue Vanda, allied to the celebrated Vanda c@rulea, but much smaller in all its parts, had been discovered by Griffith near Bamo, in Birmah, so long ago as 1837; but nothing further was known of the plant until it was rediscovered by Colonel Benson in 1867, when he communicated specimens and a coloured figure to the Kew Herbarium, from hills near Prome, at an elevation of 1500 feet above the sea. Thanks to his energy, live specimens were shortly afterwards sent to Messrs. Veitch, which flowered in the Royal Exotic Nursery, Chelsea, in March of the present year, and from which the accompanying drawing was made. ‘Though by no means comparable either for size or colour with Vanda caerulea, it is a very elegant plant, and well worthy of cultivation.

seven inches long, three-quarters to one and a quarter broad deeply channelled above, very coriaceous, strongly keeled at the back, the keel increasing in size towards the tip, where it forms an angular projection ; tip of the leaf abruptly trun- cate and two-lobed, the lobes ending in rigid angular points. facemes many, axillary, pendulous, five to seven inches long, on peduncles of equal length, green, with one or two small appressed sheaths; peduncles spreading, together with the slender ovaries one and a quarter inches long, a slightly redder lilac than the rest of the flower. Flowers one to one and one-third inch diameter ; sepals and petals subequal, spreading, incurved, rather undulate or twisted, obovate-spathulate, subacute, pale blue-lilac inside, rather darker outside. Lip rather smaller than the petals, three-lobed ; two lateral lobes small, dark blue, adnate to the sides of the very short dark blue column; mid-lobe projecting, between obovate and cuneate; margins deflexed, of the same colour as the petals ; tip rather dilated, rounded, notched ; disk violet-blue, with two thick, smooth, obtuse ridges, and a short basal inter- mediate one ; spur shorter than the lip, incurved, subacute, blue-lilac ; anther yellow.—J.

Acacia setigera, Hook., Ic. Pl., tab. 316.
This is by far the most beautiful Acacia of Tasmania, to the southern parts of which island it seems to be confined ; growing like a weeping willow on the banks of the streams that fall into the Derwent. It was discovered by Robert Brown in the early part of the century, but it was not till nearly forty years afterwards that it was made known in this country; firstly by specimens communicated to Sir Wm. Hooker by Ronald Gunn, Esq., F.R.S., and afterwards from seeds sent to the Right Hon. T. Spring Rice (then Chancellor of the Exchequer,.afterwards Lord Monteagle) ; in honour of whom it was named. It is remarkable that so fine a greenhouse ornament should be comparatively rare in cultivation; for its deep green perennial foliage, its long whip-like pendent branches, clothed with golden flowers, the facility with which it can be trained over columns and arches, and the length of time during which it remains in flower, render it one of the most desirable acquisitions for a

conservatory. In the form of the leaves, and in certain other characters, it so closely resembles certain states of Acacia mucronata, that they are often mistaken for one another; but besides the great difference in habit, there is no resemblance whatever between their pods. For cuttings of the true plant, the Royal Gardens are indebted to Mr. H. Knight, gardener to His Grace the Duke of Roxburghe, at Floors Castle, where a single plant festoons the glazed corridor for full 50 feet of its length, flowering during many months of the year, from March or April onwards.
Descr. A very handsome small dark-green tree, ten to twenty feet high, with copious pendulous slender branches, which are villous at the apices only. Phyllodia scattered or whorled, laterally appressed, very narrow, one to two inches long, linear, acuminate, pungent, less rigid than in its con- geners of this section, one-nerved. Stipules minute, broadly ovate, membranous. Peduncles slender, divaricating, longer than the phyllodia. Flowers large for the genus, solitary or aggregated by two or three together along the very slender pendulous peduncle. Bracts small, appressed to the base of the flower, ciliate. Calyx very minute, cup-shaped, three-lobed ; lobes ciliate. Petals generally three, persis- tent, glabrous. Pods two to three inches long, narrow, much curved, shortly stalked, retaining at their bases the persistent petals ; valves very convex, coriaceous, contracted between the seeds. Seeds oblong, longitudinal ; funicle much folded, and thickened nearly from the base.—/. D. H.

This very singular and little known plant has long been in cultivation in the Palm House of the Royal Gardens, and is a native of the Pacific Islands. It is closely allied to the well-known Hernandia sonora of the East and West Indian Islands, the juice of which has the property of destroying the hair without pain, when applied to the head; and the light wood of which is used for floats for fishing nets, and is said to take fire from a flint and steel, like German tinder. The genus is of doubtful affinities; being placed by some

near the order Laurinee, on account of the structure of its anthers, and by others near Combretacee, probably with better reason, from the structure of the ovary and fruit. The specimen here figured, flowered in the Royal Gardens in October, 1869.

The genus Mormodes presents some of the most abnormal forms of flower that are to be found in the vegetable kingdom, and very little indeed is understood of their nature and functions. Some are, as Darwin has shown, sexual forms of widely different looking Orchids, and others are so variable that it is impossible to characterize them specifically. Under such circumstances nothing remains but to watch their growth, figure all the forms that appear, and wait for evidence as to their true position amongst the genera ( Catasetum, Gon- gora, Monacanthus, and Cycnoches) with which they have the greatest affinity.
The subject of the present plate was published almost simultaneously by Reichenbach fil. and Lindley. It is a native of the mountains of Central America, at elevations of about 7000 feet, and was introduced by Warscewicz in about 1850; the specimen here figured flowered in Mr. Veitch’s nursery in March of the present year.

The genus Hechtia was originally founded by Klotzsch of Berlin in 1835, upon a female specimen of a very imperfectly known Mexican plant, respecting which nothing has subse- quently been published, and which would appear to differ from the plant here figured, in the wholly superior ovary and apparently unisexual flowers. To this genus the /. Ghiesbreghtii was doubtfully added by Lemaire in the year 1862, and described as having six subdidynamous stamens
JUNE Ist, 1870.
and abortive three- or more-celled ovaries, characters which are not obvious in the Kew specimens. Under these circum- stances I can only assume, that if H. Ghiesbreghtii be rightly referred to Hechiia, the latter is a polygamous genus liable to great variations in its ovary, and possibly identical with Dyckia. Indeed, the similarity of this plant to Dychia is very striking, both in habit and floral characters; but the latter genus has a wholly superior ovary, and many ovules in each cell. The order to which it belongs is, I think, clearly Bromeliacee.
H. Ghiesbreghtii is a native of Mexico, introduced by M. Verschaffelt of Ghent, in 1862, by the collector whose name it bears, and is a very attractive greenhouse plant, on account of its remarkably beautiful purple and green foliage, which is silvery below. The flowers, which appeared at Kew in July, smell of hawthorn, and are very insignificant indeed.
Descr. Stem 0. Leaves ten to eighteen inches long, most densely crowded into a rosulate mass, strongly recurved and clasping the flower-pot all round, rigidly coriaceous, three- quarters to one and a quarter inch broad at the base, gradu- ally narrowed from thence to the rigid pungent tip ; margins beset with rather distant rigid spinous teeth ; upper surface bright green from the base to the middle, blood-red or purple from thence to the tip, under surface silvery grey. Scapes several, axillary, suberect, ‘flexuous, very slender, scurfy, eighteen to twenty-four inches long; bracts sheathing, acu- minate. Flowers white, one-third of an inch in diameter, sessile in rather distant capitate fascicles along the upper part of the scape; bracteoles minute, concave, scarious, yellow- brown. Sepals linear-oblong, obtuse, scurfy, erect, half as long as the corolla, inserted towards the base of the ovary. Corolla inserted towards the summit of the ovary, 3-lobed nearly to the base; lobes rounded, spreading. Stamens six, sub-equal, inserted towards the base of the corolla, filaments broadly subulate; anthers oblong, apiculate. Ovary 3- celled, summit broadly conical ; styles three, short subulate ; ovules apparently one in each cell. —J. D. H.

This appears to be one of the most copious flowering species of Miltonia in cultivation; it was discovered by Pueppig, in Peru, and has been collected by Warscewicz and others. It was flowered first by Mr. Linden of Brussels, whose specimens were described by Reichenbach, under the above name of Warscewiczii ; these, however, only bore six to eight flowers, but more recently as many as twenty to thirty have been produced, and as we find the same number in dried specimens, this must be regarded as the normal number. In this country it has flowered repeatedly within the last two years; the flowers being, as I am informed, exceedingly variable in colour and markings. For the specimen here figured I am indebted to Mr. Bull, F.LS., of Chelsea, from whose plant the drawing was made by Mr. Fitch, in March of the present year. :

Amongst the most attractive horticultural novelties of the Spring Exhibitions, during the last two years, have been the _ groups of terrestvial Orchids, for the most part collected in vari- ous parts of Europe, by His Royal Highness the Comte de : Paris, and cultivated by him at Twickenham, and which are no less remarkable for their botanical interest than for their beauty and the perfect condition of health to which they have been brought by very simple means and appliances. Many belong to the genus Ophrys, and of these the subject of the present plate is one of the rarest and at the same time most curious ;—the brilliant polished surface of the disk of the lip, which shines like a blue-steel looking-glass, edged with gold, and that again set in a rich marvon velvety frame, presenting a combination of colours quite unlike anything else known to me in the vegetable kingdom.

a native of grassy hills in Europe, south of the Alps, from Portugal and Spain to Greece, Turkey and Asia Minor, and it crosses the Mediterranean to the Algerian coast; like its congeners it varies much in the size of the flower, the form of the lip, and relative dimensions of the purple, gold, and blue markings; the latter being sometimes reduced to one or two spots. ‘The specimens here figured flowered in a cool frame in the month of April, and were kindly commu- nicated by His Royal Highness for publication in the Bo/anical Magazine.

By far the noblest species of the noble genus to which it belongs, and of which Dr. Lindley said when originally describing it, —‘‘ No more remarkable orchid has been found in Northern India.” The flowers much exceed in size those of its congeners, and though less brilliant than many of these, are singularly rich in hue, owing to the colour number and disposition of the bright red brown transverse bars, the effect of which is not matched by any other known orchid. It is a rare native of hot damp shady valleys in the Eastern Himalaya, delighting in the neighbourhood of water- falls where exposed to constant humidity ; and has hitherto proved to be a very difficult plant to cultivate and propagate. It was discovered by myself in 1848, and transmitted to the Calcutta Botanic Gardens, where after flowering it was sent off to England, but did not survive the voyage. Repeated attempts have subsequently been made to introduce it with more or less success, and the honour of first flowering it in this country is I believe due to the Messrs. Veitch, whose
JULY Ist, 1870.
plant produced one flower in March of the present year. The plate here published is made up from this flower and the figure given in my illustrations of Himalayan plants, which is a faithful copy from a beautiful drawing (itself executed with the scrupulous fidelity of a Hindoo draughtsman), made in the Himalaya itself during my stay there, by a native artist employed at Darjeeling by my late friend Judge Cathcart. Comparing the colouring of the English-grown with the Himalayan flower, it will be seen that that of the native- grown plant is very much the finest, the bands being darker, more fulvous, and running more into one another, the lip and petals are however broader in Messrs. Veitch’s flower, and rather larger.

Very closely allied to Dracena bicolor (Tab. nost. 5248) but a far handsomer plant, three to five feet high, with a strict erect trunk, bearing a profusion of spreading and recurved leaves, which becoming gradually larger upwards give it a very noble appearance ; the leaves are further much larger and more obovate than in D. bicolor, with broader petioles, and the dense terminal spike is much larger, sessile, quite amentiform. The pedicel of the flower and its tube are more slender, as are the perianth-segments; the bracts, stamens, and ovary are similar in both.
D. cylindrica is a native of the Old Calabar River, on the West Coast of Tropical Africa, where it was discovered by Mr. Gustav Mann, when collector for the Royal Gardens, the most successful botanical explorer who ever visited the mala- rious West Coast of Africa, and who is now an assistant con- servator of Forests in Bhotan, under the Indian Govern- ment.

A more singular looking plant than the subject of this plate seldom falls under observation in a living state, its dwarf habit, gigantic flower, great snow-white erect outer perianth leaves, the equally large strangely coloured inner perianth, and the deflexed stigmas with shining black purple humped bases, the two latter organs resembling some great insect, make up a flower of singular oddity and beauty too. We have referred it to the Jris iberica of Hoffman, with dried specimens of which it entirely agrees. It differs, how- ever, from the plant figured by Dr. Regel in the Gartenflora under this name, in the obtuseness and colour of the inner perianth-segments, which are represented as ochreous-brown, and as wanting the polished almost black disk and marbled edges of our plant; the colour of these organs is however described as being excessively variable, and as ochreous- yellow in his var. ochreacea. Klatt refers the J. taurica of

Loddige’s Botanical Cabinet to this species, but I know not on what authority beyond Loddige’s figure, which is ex- tremely unlike this plant. Jris iberica is a native of the Iberian provinces of the Caucasus, and of Imeretia (not of the Iberian Peninsula) and extends into Cilicia, Kurdistan, and probably Persia, inhabiting mountains of 6500 feet high. The magnificent specimen here figured was sent for publica- tion by Mr. Ware, of the Hale Farm Nurseries, Tottenham, with whom it flowered in May of the present year.
Descr. Rootstock tufted. Stem three to six inches high, leafy. Leaves glaucous, shorter than the stem, much re- curved, falcate or revolute, linear-ensiform, two to four inches long, one quarter to three quarters in diameter, margins flat or wrinkled, membranous, as are the sheaths. Spathes two, ovate-lanceolate, rather longer or shorter than the perianth- tube, membranous except at the base. ower solitary, very large, three to five inches from the tip of the reflexed to that of the erect perianth-segments, and two to three across the former. Outer perianth-segments erect, orbicular, subcordate at the base, white, undulate, with a few red spots towards the base on the inner surface; inner segments deflexed, broadly oblong, rounded at the tip, concave with entire recurved mar- gins, yellow-green, covered with wrinkled dark-purple reticulate narrow bands: disk depressed, black-purple, shining. Stigmas reflexed on the disk of the inner perianth-segments, obovate- oblong, keeled, with broad 2-fid recurved toothed tips, dull

This tropical aroid, conspicuous for its ample foliage, snow- white spathes, and fine purple spadices, has been long culti- vated in the Royal Gardens, and appears to be the same with the Anthurium ornatum of Schott, discovered in Venezuela by Linden in 1842, and again gathered’ by Fendler in 1854-5. The leaf varies much in size, often attaining one to one and a half feet in length, and in the form, depth, and amount of divergence of the basal lobes. The specimen here figured was from the rich collection of Mr. William Saunders, F.R.S., and flowered in April of the preceding year.
Descr. Stem 0, or very short indeed. Petioles one and a half to two and a half feet long, slender, rigid, cylindric, green; swollen at the base into an ovoid, very coriaceous sheath, with a narrow slit in front, and at the lip into a cylin- dric green node one to two inches long.

A pretty perennial-leafed hardy Saxifrage, a native of crevices of rocks in the Pyrenees, and apparently confined to that mountain range, but closely allied to S. diapensoides, 8. cesia, and others of the same group, which extends from the Spanish Alps to the mountains of Turkey and N. India. The habit is very much that of various species of tufted Alpine Androsace (Aretia L.), but the persistent foliage and the facility with which it may be propagated renders it a far more eligible rockwork plant than these.

This very handsome Brazilian Tillandsia appears to have been introduced by M. Linden from Brazil into Europe, through Mr. Wallis, and published almost simultaneously by Dr. Regel, of St. Petersburgh, under the name of Tillandsia Lindeniana, and by Professor Morren, of Liege, under that of Zillandsia Lindeni. It is the largest flowered species of the genus known to me, and very remarkable for the curiously soft texture and hue of the deep violet-blue petals ; the colour of which melts into a pure white at the base of the blade.
The specimen here figured was communicated by Mr. Ware, of the Hall Farm Nurseries, Tottenham, with whom it flowered in May of the present year; and it is stated in the Gardener's Chronicle to have been shown by Mr. Williams

Crmsipium canaliculatum, Br. Prod. p. 331. Lindl. Gen. and Sp. Orchid. p. 164. Mueller, Fragment. v. 5, p. 95.
A native of Cape York, in North Eastern tropical Australia, where it was collected by Robert Brown in the beginning of the century, and again by Mr. John Veitch, F.LS., who sent it to England during his collecting voyage to Australia and the Western Pacific, which resulted in the making known of so many interesting plants and beautiful horticultural novelties. Mr. Veitch’s specimen appears to differ a little from the description of Brown’s plant in the more obtuse perianth- leaves, and in the lip being 3-lobed at the middle rather than the apex. After carefully comparing the flower, however, with excellent specimens of those of C. canaliculatum, sent by Dr. Mueller from Arnheim’s Land, by Oldfield from Hunter’s River, New South Wales, and from subtropical Australia, collected by Bidwill, I find it impossible to establish any satisfactory character whereby to distinguish them. A more obvious point of difference is the much larger bracts of the Arnheim’s and Hunter's liver plants; but these are as small in Bidwill’s specimen as in Mr. Veitch’s.
AuGuUsT Ist, 1870.
This plant would thus seem to be variable, and to have a very wide range in distribution, from the temperate climate of Hunter’s River, in lat. 33° 8., to the torrid and arid shores of Arnheim’s Land, in 13° N., and Cooper’s Creek in Central Australia, in which latter localities Mueller states that it is the only known orchid.
The specimen here figured flowered in Messrs. Veitch’s
nursery in April, 1870.

Flowers coriaceous, two-thirds of an inch diameter ; perianth-segments thickly coriaceous, spreading, inner rather smaller, elliptic- oblong, subacute, concave, brown with green margins, back -greenish-brown, inner deeper coloured. Ly shorter than the petals, recurved, white with pinkish blotches, 3-lobed at the middle, lateral lobes narrow and small; mid-lobe ovate subacute ; base between the lateral lobes with two low ridges.

It is remarkable that so very elegant a plant as this, and one introduced into England as long ago as 1710, should never yet have been figured in any English work, and indeed almost fallen out of cultivation. It is a native of the South of France, Spain, Italy, Greece, and Asia Minor, and of Morocco in North-west Africa, From the latter country we received seeds from our active and liberal correspondent, Mr. Maw, who collected them in a botanical excursion to Spain and Tetuan in 1869, which resulted in the introduction into Europe of many charming hardy plants, including Linaria tristis (Tab. 5827), and Cotyledon Salzmanni (Tab. 5801).

proper, Anona reticulata, and of the true Papaw, Carica Papaya.) “ Asiminier,” was the name applied to it by the early French colonists of America.
Asimina triloba was introduced into England by Peter Collinson in 1736, and probably old trees of it may still linger in Botanic and other Gardens. The plate here given is from plants raised from seeds presented to the Royal Gardens by Professor A. Gray, of Cambridge, U.S.A., which were trained against a wall, and flowered in June of the present year.
Descr. A small deciduous-leaved shrub or small tree, with dark brown bark and fcetid wood. Leaves six to twelve inches long, very membranous, shortly petioled, obovate or oblong-lanceolate, abruptly acuminate, slightly pubescent beneath, young buds covered with shining ferruginous pu- bescence, nerves slender, spreading. Yowers appearing with the young leaves, but from separate buds, solitary, shortly peduncled, drooping, two inches diameter, young clothed with small deciduous scales ; peduncle cylindric, one inch long. Sepals three, broadly ovate obtuse or orbicular, concave, de- ciduous, green. Outer petals two or three times as long as the sepals, twice as long as the inner, broadly ovate, spreading, and recurved, obtuse, green at first and crumpled, then dull brown, deeply reticulated and rugose ; inner similar, with a yellowish interrupted band across the middle. Sfamens in a globose mass on the torus, minute, yellow. Ovaries five, green. Fruit of one to three cylindric berries, two to five inches long. Seeds one inch long, oblong, compressed, imbedded in a fleshy aril ; testa crustaceous, shining.—/. D. H.

A rather rare native of bogs, from the Central and New York States of N. America to Kentucky and Wisconsin, extending thence into Canada to the northward, and to the Platte Plains and Rocky Mountains to the westward. As a species it is closely allied to the more common Ameri- can yellow-flowered C. pubescens (Tab. Nost. 911, sub nom. parvifori) and C. parviflorum (Tab. Nost. 3024), from which in a dried state it is with difficulty distinguishable, but from both of which the colour of the flower separates it, whilst the former has a much larger flower and more globose lip. Like all the horeal Cypripedia, this is easily cultivated in a bog soil, with a cool bottom, plenty of shade, and a copious litter- ing of dead leaves. The specimen figured was from roots communicated by Mr. J. Dunlop, of Milwaukie, US. America, which flowered at Kew in May of the present year.

Sepals one inch long, slightly pubescent, green, with brown- purple nerves and tip; dorsal ovate-lanceolate, acuminate, twisted ; two lateral connate into an ovate-lanceolate, two- toothed blade placed under the lip. Petals larger than the sepals, of the same colour, narrow, twisted, spreading. Lip two-thirds of an inch long, oblong, rounded at the tip, inflated, rather flattened at the sides, white with purple spots round the mouth and within opposite the mouth, neck villous and yellow within.

I regret to have to state that the history of the plant here figured is quite unknown to me. It has been cultivated in the Royal Garden for a good many years, flowering annually, and has been seen by various collectors, none of whom have recognised it. In many of its characters it resembles the C. Pitajaya, Jacq., of Brazil, which is merged with some eight or ten garden and other species into one called C. varia- bilis by Pfeiffer, and I should not be at all surprised if it proved to be a hybrid between that plant, which is white-flowered, and some scarlet-flowered Cactus ; though it differs from C. variabilis in the laxer habit, and flowering only in the even- ing and night. The habit indeed is that of C. speciosissemus. It flowers in July, the flower opening in the early evening and remaining expanded till the following noon.
Descr. Stems pale bright green, not glaucbus, 2 to 3 feet high, 3- to 4-angled, one inch and a half diameter, angles much compressed, starting from near the axis, so that on a transverse section the wings or angles appear as narrow

arms about one-eighth of an inch thick; margin obtuse, notched at intervals of one to one inch and a half ; areole at the notches small, with yellow tomentum ; spines about half an inch to three-quarters long, slender, straw-coloured, tipped with brown, about three of them central. FVowers situated at the notches, six to seven inches diameter. Calyx-tube three to four inches long, three-quarters of an inch in diameter in the middle, laxly pilose with long soft hairs, obscurely ribbed, clothed with scattered ovate-lanceolate acuminate incurved bracteoles one-third of an inch long.

Stamens very numerous, shorter than the petals. Style longer than the stamens, very stout; stigma with about fifteen subulate rays. Ovary ovoid, scarcely broader than the calyx tube.—/. D. H.

Though differing from all of the four previously described species of Brodiza, in the length and cylindric form of the perianth, and in the great size of the scales at its mouth, I am disposed to think that Dr. Gray is right in referring it to that genus, and abandoning the genus Brevoortia, which was made by Professor Wood for this plant, and not without ap- parent good cause, for in the form of its perianth and size of the scales it differs widely from its congeners. It need hardly be added that Dr. Gray is justified in discarding “ the objec- tionable double-headed specific name (Ida. Maia), given by the stage driver, Mr. Burke, who showed the plant to Pro- fessor Wood, in affection for his little daughter.’
SEPTEMBER lst, 1870.
Brodiea coccinea is a most brilliant-flowered bulb, a native of Shasta County and Humboldt County in California, where it was discovered by Mr. Lobb, and afterwards collected and named by Wood. More recently it has been sent to England by Mr. Bolander of San Francisco, and flowered both with Mr. Thompson of Ipswich, and in the Royal Gardens of Kew, May and June.
Descr. Bulb the size of a small chestnut. Leaves ten to eighteen inches long, one quarter to one-third of an inch broad, linear, obtuse, concave above, convex on the back. Scape equalling the leaves, slender, erect. Umbels five to fif- teen-flowered ; bracts membranous, lanceolate, shorter than the curved pedicels. Mowers drooping, one inch and a half long, rather blood-red than scarlet, abruptly replaced by yellow below the lobes, which are green. Perianth-tube six- lobed at the base, inflated above the middle; lobes short, oblong-ovate, obtuse, recurved. Corona of six erect mem- branous cuneate erose scales at the mouth of the perianth. Anthers sessile, their tips exserted. Disk obscure. Ovary elliptic-ovoid. Seeds oblong, black.—J. D. H.

A handsome shrub, six to eight feet high, discovered by the lamented collector Barter during Baikie’s Niger Expe- dition at Eppah, and since collected by Dr. Irving at Abeo- kuta in the interior of the Slave Coast, and by Mann on the Old Calabar river. From the latter country live plants were sent by the Rev.W. C. Thomson of Old Calabar to the Edin- burgh Botanic Gardens, whence the specimen here figured was sent to Kew by Mr. M‘Nab, and flowered in spring of the present year. As a species it is closely allied to the T. subsessilis, Benth., a native of Liberia and Ambas bay to the westward, but differs decisively in the leaf being narrowed into an acute base; the follicles are also more recurved and beaked.

A tall hardy herbaceous plant, with a woolly suffrutescent stem, belonging to the same set of sages with S. officinalis, and many other handsome species that are common orna- ments of continental gardens, but are all but wholly unknown in our own. It was, according to the Hortus Kewensis, formerly cultivated in the Royal Gardens under the name of the Ash-leaved sage, having been originally introduced from Morocco into the Cambridge Botanic Garden, L798. It has, however, long since disappeared from cultivation, and so re- mained till three years ago, when it was re-introduced from Tangiers by G. Maw, Esq., of Benthall Hall, during a botanical expedition into N. Africa, from whence he sent living plants to the Royal Gardens that flowered in May of last year. From its habit of flowering through several suc- cessive months, it is well worthy of cultivation in the open

Duscr. Stem erect, shrubby below ; branches, inflorescence, and calyx covered with viscid down. Branches slender, four- angled, erect, rather distantly leafy. Zeaves six to ten inches long, spreading, pinnatisect, green and coarsely rugose above, clothed below with white tomentum; terminal lobe two to three inches long, oblong-ovate, obtuse or acute, rounded or cordate at the base, strongly nerved, coarsely reticulate and deeply pitted beneath, margin irregularly crenate ; lateral segments distant, often alternately large and oblong and small and rounded, sessile or shortly petioled. Whorls of flowers nu- merous, two to three inches apart, five to ten lowered. Flowers nearly sessile; bracts minute, ovate, acute ; bracteoles shorter, broader. Calyx viscid, half an inch long, deeply grooved, tubular campanulate, shortly two-lipped; teeth triangular, acute, upper dorsal very small, obtuse. Corol/a one inch and a quarter long by one inch diameter, dark violet purple, with a white throat; tube exserted, nearly straight, smaller at the throat, red purple. Upper lip short, nearly horizontal, laterally compressed, obcordate, two-lobed at the apex ; lower lip three-lobed ; lateral lobes broad, rounded, reflexed; middle rather deeply lobed, rounded, recurved; palate prominent, and throat white with purple streaks.

Lissochilus Krebsii was first described by Reichenbach in 1847, from specimens sent to Europe by the collector whose name it bears. For that here figured, the Royal Gardens are in- debted to their old and valued correspondent, John Sanderson, Esq., of Natal, who contributed living plants in 1867 along with those of three other species of this interesting genus. It has also been received from Mr. McKen, of the Natal Botanic Gardens; and we have dried specimens from Mr. Gerrard (who died subsequently when botanizing in Mada- gascar), also collected in the Natal colony a good many years ago. Though closely allied to several Kast-tropical African species, collected by Drs. Kirk, Meller, and others, during Livingstone’s second expedition, it does not seem to be identical with any of these, having a broader midlobe of the lip and longer spur.

Descr. Pseudo-bulbs two to three inches long, ovoid, or elliptic-oblong, green, marked with few concentric scars. Leaves in copious tufts from the base of the pseudo-bulb, sessile, very shortly sheathing, eight to twelve inches long, two to three inches broad, elliptic-lanceolate, acuminate, plaited, strongly ribbed, bright green, paler beneath. Scape two to three feet high, stout, terete, inclined. Raceme twelve to eighteen inches long, twenty- to thirty-flowered.

The beautiful genus Calochortus was first brought to notice in England by the late David Douglas, who, during his ex- ploration of the north-west districts of North America, trans- mitted bulbs of various species, both of this and of its close ally, Cyclobothria, to the Horticultural Gardens, some of which were figured in the early numbers of the Botanical Register, and in the “ Transactions of the Horticultural Society” (v. vii., t. 8 and 9, v. viii. t. 14 and 15, &c.), and in a few other works. These all, however, very soon disappeared from cultivation, no doubt owing to neglect during their long dormant, or flower- less, season. Now, however, after a lapse of nearly forty years, they are again coming into cultivation, and will, I hope, prove to be permanently established favourites. The species here figured differs from any of the twelve or more that have been described, or are preserved, in our Herbaria, and far exceeds in showiness the graceful little plant figured in our last year's volume as C. wniflorus (Tab. 5804) ; it was dis- covered by Mr. Roezl in the Sierra Nevada of California, and
OCTOBER Ist, 1870.
transmitted by him to our excellent correspondent, Max Leichtlin, of Carlsruhe, who sent bulbs to the Royal Gardens in November last. These flowered in June of the present year, and are here figured. The flowers open almost in pairs at a time, and last for several days in perfection. As a species it is very near the C. venustus, Benth. (Bot. Req., t. 1669); but the plant is much smaller, leaves narrower, flowers much smaller, with only a single purple spot on the sepals above the nectary, and no purple band below the nectary ; the sepals, too, are not green.
Descr. Bulbs ovoid. Scapes four to severincheshigh, slender, erect or inclined, terete, leafy. Leaves very narrow, one-eighth to one-sixth of an inch, sheathing, glaucous-green, gradually narrowed from the sheath to the tip, rounded on the back, very concave in front; margins incurved. Sypathes like the leaves, hardly exceeding the flowers. Flowers two inches and a half in diameter when fully expanded ; peduncles yellow-green. Sepals ovate-lanceolate, acuminate, recurved, concave, white, with a broad purple-brown streak on the back, tips pink. Petals broadly obovate-cuneate, apiculate, obscurely erose, con- cave at the base, gibbous at the back, reflexed from above the middle when fully expanded, white, with a single purple blotch above the nectary ; nectary semicircular, green, sur- rounded with a pale yellowish blotch, and some slender filamentous hairs. Anthers linear-oblong, yellow. Ovary

A most lovely representative of one of the most variable genera of hardy annuals, the limits between the species of which are as difficult to draw from living specimens as from herbarium ones. I have referred the subject of the present Plate to L. parviflorus, though its flowers are so much larger than those of the typical states of that plant, being able to find no other difference but this of size (they are fully twice as large as in most states of Z. parviflorus) and of colour, which however varies in the typical plant from white to lilac and yellow, and in this variety from a very pale to & very deep rose-red. In respect to the size of the flower
Octozer Isr, 1870.
it agrees with LZ. androsaceus (‘Tab. Nost. 3491), one of the largest flowered of all, but which has much narrower corolla lobes, of a very different shape. L. grandiflorus and L. densi- Jlorus (Tab: Nost. 3578), also as large flowered, have on the other hand, a very short corolla tube.
I am indebted to Mr. Thompson of Ipswich for the fresh specimens from which the accompanying drawing was made; and which flowered in his nurseries in June of the present year. It is a native of California, and perfectly hardy ; but probably, like its congeners, does best in rather a damp climate.
Duscr. A slender annual. Stem very variable; height four to ten inches, wiry. Leaves half to three-quarters of an inch long and broad, palmately cut to near the base into slender linear spreading apiculate lobes, dark green, pilose with soft white hairs. Mowers crowded, erect. Calya- lobes subulate. Corolla-tube an inch to an inch and a-half, white or nearly so. Limb half to three-quarters of an inch in diameter, pale or deep rose-coloured, with a white or yellow eye; segments orbicular and somewhat overlapping, quite entire. Stamens included, yellow.—/. D.

Though displaying none of the beauty of the commoner cultivated Passion-flowers, and wanting their scandent habit, copious festoons of leaves, and elegant tendrils, the subject of the present plate is still a very interesting one, from its erect habit and large foliage; in which respect it stands almost alone amongst its 120 congeners. Dr. Masters, who has given a careful detailed description of it in the Gardener's Chronicle, and who quotes the observations of its introducer, Mr. Cross, made in its native woods, describes it as growing from one to twelve feet high, bearing few beautifully smooth dark green pendulous leaves, one to three feet long, and looking like a green umbrella stuck in the ground.
P. arborea is a native of the damp shady forests of the moun- tainous districts of New Grenada, Equador, and Venezuela, extending to an altitude of 6000 feet above the sea, where it

was discovered by Humboldt and Bonpland in the beginning of the century. There is a fine suite of specimens of it in the ‘Hookerian Herbarium,’ collected by Triana, Linden, Spruce, Fendler, and Goudot.

An inhabitant of the volcano of Cheriqui in New Grenada, near Veraguas, where it was discovered by Dr. Seemann, when Botanist on the voyage of H.M.S. Herald, in 1849, and by whom living plants were sent to Kew, which have long been cultivated in the Palm House of the Royal Gardens. It has also been found at Panama, by the late Mr. Sutton Hayes; at La Paila, in New Grenada, by Holton; and near Truxillo, in Venezuela, by Linden; for I have little hesitation in re- ferring the C. roseflora of Planchon and Linden to this plant, our specimens, indeed, presenting characters that unite them. Like various other Clusias, this is a subscandent, or half- epiphytic shrub when young, which, after it has established itself and attained a sufficient height, supports itself by its thickened and interlacing roots, as a small tree, without other support. ae
The plant from which the accompanying drawing was made
OCTOBER 1st, 1870.
flowered in August, 1869. Its native name is Copecillo odoroso.
Descr. A small bushy tree, twenty to twenty-five feet high. Branches nearly terete. Leaves three to five inches long, by one to two inches broad, obovate-cuneate, or oblanceolate- cuneate, obtuse or subacute, narrowed into a distinct stout petiole, a quarter to half an inch long, uniformly green and smooth on both surfaces ; midrib distinct when dry, when also the nerves appear as faint, close-set streaks. Flowers usually two to three, pedicelled on a short stout cylindric peduncle, one inch and a half diameter, much like those of a dog-rose, pale rose-red, odorous; bracts and bracteoles not broader than the peduncle and pedicel, rounded, compressed. Sepals four to five, orbicular, concave, half as long as the petals. Petals broad, orbicular-obovate, or almost obcordate, concave below the middle. Staminal cup half embracing the ovary. Ovary green, with a sessile five to eight-lobed stigma. Capsule five to eight-lobed; valves narrow, recurved. Seeds with a fleshy red aril.—J. D. H.

Barteria Mackenii ; glaberrima, caule obtuse 4-gono, foliis recurvis anguste ovato- v. elliptico-lanceolatis subacutis petiolatis tenuissime strigillosis integerrimis, floribus terminalibus paucis in axillis supremis, bracteis parvis subulatis, sepalis exterioribus amplis late-ovato v. rotundato- cordatis obtusis venosis, interioribus parvis e basi ovato subulato-acumi- natis, corolle purpure tubo infundibuliformi calycem equante, limbi lobis subsequaliter rotundatis basi atro-purpureis, staminodiis 3, 2 late- ralibus minutis subulatis intermedio lato apiculato approximatis.
A close ally of the Barleria Gibsoni (Tab. Nost. 5628), which it resembles in the corolla, but differs remarkably in the form of the bracts and sepals. It was discovered in the Latin goldfields district of the Natal colony, whence dried specimens were communicated to me by Mr. McKen, of the Natal Botanic Gardens, and who also sent fresh seeds of it from that interesting district in November of last year, from which the plant here figured was raised at Kew in spring, and flowered in June of the present year. We have also dried specimens collected by Messrs. Chapman and Baines, during their journey towards the Zambesi, in lat. 23° S., in the year 1863. Like many of its congeners which inhabit the Peninsula of Hindostan, it probably flowers in the beginning of the cool dry season, and would under proper treatment form a charming acquisition for the winter decoration of a moderately heated house.
The district in which this Barleria_is found appears to be botanically little known, and to abound in novelties. Amongst others which Mr. McKen has procured, are two

Dr. Asa Gray, the authority for this species, describes it as “the most splendid of all the Godetias, and very desirable for cultivation, from the fine colour and great size of the flowers crowded at the summit of the stem,’ and states that he has named it after Professor Whitney, the distinguished head of the Californian State Geological Survey; in the prosecution of which it was discovered. It was first col- lected by Dr. Bolander, botanist to the Survey, on the plains at Shelter Cove, Humboldt County, California, in 1867; and the specimen here figured, which by no means exceeds in beauty and size of flower (which in Gray’s description and dried specimens are four inches in diameter) the native specimens, was raised from seeds sent by Mr. Bolander to Mr. Thompson, of the Ipswich Nurseries, who flowered it last summer in perfection.

Lingua, which is emphatically called by Reichenbach ‘decus Floris Mediterranez,”’ extends from Crete and Smyrna to Portugal. S. cordigera has a still wider range, from Syria and the Taurus to the Azores—a very unusual distribution for an orchid that is restricted in lati- tudinal range, and which, though abundant in North Africa, does not extend to Madeira or the Canary Islands. Both species are found in Algeria.
The species of Serapias are easy of cultivation in thoroughly drained pots, with a light loamy soil, where they form their leaves in winter, and flower in early spring. The Royal Gardens have received tubers of both species from J. T.

In its robust shrubby habit, and stout raceme of large flowers, this forms a strange contrast to the delicate looking and feathery-foliaged G. Preissii figured in the early part of this volume (Tab. 5837), and is one of many instances of the remarkable differences in habit displayed by various members of many of the large Australian genera. It forms a tall shrub or slender tree, of fifteen to twenty feet in height, and when covered with its scarlet blossoms, must present a mag- nificent ‘appearance in the Australian bush. The genus to which it belongs contains upwards of one hundred and fifty species, of which all but two or three (New Caledonian) mem- bers belong to Australia; many are as deserving of cultiva- tion as that here figured, but like most Australian hard- wooded plants they require a peculiar treatment, so different from that of ordinary greenhouse stock of the present day, that as a rule they are usually rapidly killed by mistaken

kindness, succumbing under the favourite regimen of too much heat during winter and a perennial drenching with the watering-pot. In a stiff well-drained soil, sparingly watered in the growing season, and hardly at all at other times, they succeed well, give little trouble, and amply repay the cultiva- tor’s care.
Grevillea Banksii is a native of barren hills in the Queens- land colony, where it was discovered by Brown during Flinders’ voyage, and has since then been found by various collectors: the plant here figured, which was five feet high, was raised and flowered by Messrs. Osborn of Fulham, who liberally sent it to Kew for figuring in the Magazine in August last.
Duscr. A tall shrub or slender tree of fifteen to twenty feet; branches and inflorescence softly tomentose. Leaves four to eight inches long, deeply pinnatifid or pinnatisect, with three to eleven broadly linear or narrow lanceolate seg- ments, which are obtuse or mucronate, with recurved margins, two to four inches long, glabrous above, silky underneath, the midrib alone prominent or obscurely penniveined ; here and there a small undivided leaf occurs. Racemes terminal, erect, dense, two to four inches long, solitary or two or three on a terminal leafless peduncle. Vowers red. Pedicels three to four lines long, tomentose as well as the rhaches. Perianth tomentose outside, glabrous inside, the tube not very broad, six or seven lines long, contracted and revolute under the limb. Torus straight, or nearly so.

considering this and all the other species of Dodecatheon are bat varieties of the original D. Meadia, into-which all pass by insensible gradations. Of these the subject of the present plate is one of the most distinct in size, in the brilliant colour of its few flowers, in its few small involucral bracts, and in its narrow dark stamens; but none of these characters are constant, least of all that of colour, which varies to lilac and white; whilst the petioles of the leaf are sometimes as long as the blade. It isa singular fact that a genus so widely dispersed as Dodecatheon is, throughout a belt of thirty degrees of latitude, and extending in longitude right across America, and to the islands of the Aleutian Sea, and Behring’s Straits, should be found only on one spot on the opposite coast of N. America, and not extend westward of the Gulf of St. Lawrence.
The specimens from which our plate was taken were raised from seed collected in the mountains of British Columbia, and which flowered at Kew in May of the present year. It is by far the most brightly coloured form hitherto discovered, and is very ornamental.——/J. D. H.

A very curious and pretty little plant, which I refer without doubt to §. fimbriata of Lindley, though I do not find the petals to be lacerate at the edge, as described by that author, but only erose on the margins under a high magnifying power, as are the sepals and labellum, though in a less degree. It is a native of various parts of the Cape district, from Grahams- town to Port Natal, and is evidently a very variable plant, for I find two forms of it in a collection of drawings of Cape orchids made by Mr. Saunderson of Natal (and of which he has kindly allowed me to keep copies). Of these forms neither quite agrees with that here figured, both have larger leaves, in one these are quite unspotted, and the lobes ot the lip are
broader ; in the other the leaves are obscurely spotted, the
bracts larger than in our figure, and the lateral lobes of the
lip deeply toothed on the outer margin. The flowers are

A near ally of the long known G. psittacinus, Hook., of our gardens (Tab.

There is also in the Hookerian Herbarium, a specimen, apparently of the same species, though with more speckled flowers (judging from its dried state) gathered near the “Fat river” (probably the Vet river in the Orange River Republic), by Mr. Burke, when collecting animals and plants for the late Earl of Derby. Both these specimens are labelled in the Hookerian Herbarium G. natalensis, by Mr. Klat, the author of an elaborate memoir on the Iridew in the Linnea (v. 32, wherein the unpublished name of G. natalensis Reinw. MSS., is without reason substi- tuted for that of psittacinus). Though the flowers of psitta- cinus and Saundersii are not easily distinguishable in a dry state, the leaves are so, those of the latter species being much narrower and longer, with very strong shining ribs.

A native of Sierra Leone, whence living specimens were sent to the Royal Gardens by our valued correspondent H. Bockstatt, Esq., and which arrived in full flower in a Ward’s-case in September of the present year.
E. Helleborina, so called from its resemblance to the Helle- borine (Epipactis latifolia), differs much from its congeners in wanting the pseudo-bulbs uniformly ascribed to the genus, but which are equally wanting in Z. ensata, Lindl. ( Bot. Reg. t. 1147), also a native of Sierra Leone; and in the very short column being completely concealed by the dorsal sepals and petals, which arch forward and form a sort of helmet over that organ. In colour of flower and form of lip it much resembles the W. African LZ. guinieensis (Tab. Nost. 2467), but differs widely in habit.
The genus Eulophia is a very large one, it abounds in tropical Africa, and extends thence into India, and is divisible into several very distinct sections, if not different genera.

Spzke slender, six to ten-flowered ; bracts leaf-like, the lower much larger than the flower, upper smaller, all ovate or ovate-lanceolate, acute, sessile. Flowers sessile, distant, horizontal. Ovary arched, three- quarters of an inch long, cylindric. Perianth one to one and a quarter inches in diameter from upper sepal to tip of lip. Upper sepal faleate and fornicate, linear, obtuse, together with the very similar petals forming a small hood over the column, all of them green inside, with broad brown edges, and midrib on the outside. Lateral sepals rather larger, spreading and recurved, with incurved tips of the same colour. Lip much larger than the sepals or petals; limb semicircular, with a broadly cuneate base that is suddenly contracted into a rather broad claw with two ridges, margin irregular, tip cleft. Spur with a very broad subconic base, and short, truncate, or 2-lobed tip. Column short, broad, concealed under the dorsal sepals and petals.—J/. D. Z.

This is another New Grenadan and Equador Tacsonia of the same section as 7 mollissima (Tab. Nost. 4187) and T. eriantha (Tab. Nost. 5750), from both of which it differs by slight, and perhaps not altogether constant characters— from mollissima in the much less tomentose branches, stem, and leaves; from eriantha in the shape of the bract-tube, which is here not ribbed and veined; and from both in the far more beautiful flower, which is of a bright rose-crimson colour. It is a native of the Quitenian Andes, whence we have dried specimens collected by its discoverer, Hartweg, who states that it grows wild in ravines near the city, and is also culti-
- vated ;—from Dr. Jameson, who gives its range in altitude as 8500 to 13,000 feet ;—from Spruce, who found it in woods on the western slopes of Pichincha ;—and from McLean, gathered in Peru (but without locality). There are still several other very similar Venezuelan, New Grenadan, Equadorian, and — Peruvian species of this section to be introduced, amongst which it is very difficult to find specific characters, if indeed most may not prove to be varieties of one widely diffused

species which extends along the mountains of the coasts of the Caribbean sea or Spanish main, from the mouths of the Magdalena to Venezuela, and thence along the Andes to Peru.
Flowering specimens of 7. quitensis were first sent to me by Isaac Anderson Henry, Esq., F..S.,in July of this year, and the specimen here figured flowered in the Temperate House of the Royal Gardens in October. The plants in both cases were raised from seeds sent by Professor Jameson, so long Professor of Botany in the University of Quito, and the zealous explorer during forty yearsof Andean botany, who has now removed to the University of San Juan, on the west side of the Andes of Chili; a country of which exceedingly little is known botanically, and from whence we expect many novelties from our old friend.—/.

The genus Geissorhiza includes some twenty species, all natives of the Cape Colony, with the exception of an un- described Madagascarian, and an Abyssinian one ((@. adyssi- nica, Br.), which extends from Abyssinia across tropical Africa to the Cameroons Mountains, in the Bight of Benin (G. montana, Hk. F.), and to which Klat has further referred a Cape species. Of all these not one approaches either in stature or size of flower the subject of the present plate, of which bulbs were sent to the Royal Gardens in 1866, by Mr. Wilson, keeper of St. George’s Park, Port Elizabeth, and which flowered first in May, 1868..
