Unfortunately the male cones ripened so long before the female were in good condition, that ferti- — lization was not possible by these. Mr. Bull has, however, used the pollen of Macrozamia spiralis for this purpose, and — fully formed seeds have been produced, but it remains to be — seen whether these contain an embryo, or only albumen; it _ being a well-known fact that Cycadee freely form, without __ fecundation, seeds which are to all appearance perfect, but JANUARY Ist, 1872. etter which have no trace of embryo. The genus Macrozamia is confined to Australia, where it inhabits both the tropical and temperate zones, extending to the Swan River settlement in the extreme south-west of the continent. Six species are cultivated at Kew: 4. spiralis, Frazeri, Preissii, Macleayi, Mac- donellii, and Paulo Guilielmi, to none of which does this bear | any resemblance at all, nor does it coincide with the characters of the two other species, described in Miquel’s monograph of the order: IZ. Peroffkyana, and Oldfieldic. Drscr. Trunk subspherical, with a truncate base, eight inches in diameter. Leaves six to ten inches, forming a very contracted crown, diverging below, then suberect, rigid, twisted and flexuous, linear, pinnate; petiole deep green, smooth but not polished, reddish-brown towards the base, where it is slightly and bluntly 2-edged; pinne about fifty pairs, opposite and alternate, five to seven inches long, one-third inch broad, very narrow linear-lanceolate, acute but hardly pungent, base contracted, nearly three-fourths of an inch apart in the middle of the rachis, closer above, more distant below, the lower not shorter but with a very few undeveloped ones forming short spinous processes on the petiole; dark green but not shining above, pale, and 8 to 10-nerved beneath; petiolule bright red, rather swollen, not twisted, but obliquely inserted in the rachis by an oblong subdecurrent pulvinulus. Male cone on a stout smooth peduncle three inches long, glaucous-green, seven inches long by nearly two broad, narrow oblong; scales cuneate, shortly pedicellate; terminal boss dilated, trans- versely rhomboid in front, with a similar central raised area, which bears a mucro on the lower scales, and an erect spine half an inch long on the upper scales ; pollen-cells globose, covering the whole under-surface of the scale. Female cone also glaucous-green, on a very much stouter peduncle (one inch in diameter) than the male, broadly oblong, when in fruit four and a half inches long by three and a half broad, scales about sixty, suborbicular with a short stout pedicel ; terminal boss transversely oblong, one and a half inches across, tumid, with a prominent transverse central ridge that gives rise to a triangular mucro in the lower scales, and — an erect spine in the upper. Seeds (perfect?) orange-red, subglobose, three-quarters of an inch in diameter, contiguous . —J. D. H.

GLADIOLUS purpureo-auratus ; caule elato gracillimo, foliis scapo multoties brevioribus breviter ensiformibus acuminatis strictis erectis, scapo simplici v. diviso, racemo laxifloro inter flores nudo, floribus fere bifariis, bracteis lanceolatis tubo perianthii longioribus pallide viridibus, perianthii subhorizontalis tubo brevi, limbi equali late campanulati segmentis late obovato-spathulatis apicibus recurvis obtuse acuminatis aureis, interioribus angustioribus, 2 anticis disco late purpurato, stigma- tibus lineari-spathulatis emarginato-2-fidis. The Natal Colony appears to be the head-quarters of the handsomer and more varied species of this fine genus; only last year the contrast was pointed out between the lurid, snake-headed flowers of @. dracocephalus (Tab. nost. 5884), and the vivid colouring of G. Saundersi (Tab. nost. 5873) ; to these must be added the most gorgeous of its race, G. cruentus (‘Tab. nost. 5810), and now, in the present plate, one of the most graceful and delicate, which is further remarkable for the pale golden-yellow of its flower, a very unusual colour in the - genus. Mr. Baker, who has paid special attention to this genus, informs me that it is undescribed, and is not identifi- able with any species in the Herbarium at Kew, but that it is nearest to G. hirsutus (Tab. nost. 574) and G. Gondavensis, Hort. ; the former of which is a hairy pink-flowered species, and the latter a yellow one. G. aurantiacus, Klatt, another yellow flowered species, has a much longer perianth-tube. Gladiolus purpureo-auratus was imported from Natal by Mr. Bull of Chelsea, to whom I am indebted for the specimen JANUARY Ist, 1872. here figured, which flowered in his establishment in August — of the present year. q Drscr. Quite glabrous. Stem very slender, with the scape three to four feet high. Leaves short for the size of the — plant, six to nine inches long, by three-quarters of an inch © broad, acuminate, dark green, stout, erect. Scape simple — or divided, very slender, 10 to 15-flowered, terete, quite naked between the flowers, from the bracts not sheathing the internodes. Spike eight to nine inches long. lowers almost bifarious ; bracts one to one and a half inch long, lanceolate, acuminate, exceeding the perianth-tube, pale green. Perianth- tube a quarter of an inch long, concealed by the bracts; limb broadly campanulate, one and a half inch in diameter, nearly regular, pale golden-yellow with a large purple irregularly elongated blotch which is broader at the apex, on the disk of the two lower segments ; outer segments broadly ~ obovate, with slightly recurved subacute tips, inner narrower and more spathulate.

Kenta pteroneura, De Cand. Prod., vol. vi. p. 338. The subject of the accompanying plate is an example of an essentially South African group, inhabiting northern Africa, and is further remarkable as forming a connecting link be- tween the vegetation of the three very remote geographical botanical districts of South Africa, the Canary Islands, and Arabia. In so far as I am aware, no Senecio of this habit has been found elsewhere in Northern, nor anywhere in Tropical Africa. Like many outlying species of genera with restricted limits, it departs a little from the characters of its immediate congeners; in this case in its remarkably odorous flowers, whose heliotrope-like scent is the chief merit the plant possesses as an object of cultivation to any but the lover of the curious. Senecio pteroneura is a native of rocky and sandy hills on the Maroccan coast near Mogador, where it forms a lax leafless shrub, that supports itself in thickets of Retama and JANUARY Ist, 1872. other shrubs; it was discovered there by Broussonet many years ago, but only introduced into England last spring, where it flowered in the Royal Gardens in the following November. The genus Kleinia, to which the species of Senecio with small conical tips to their style-arms have been hitherto referred, and which would have been a very natural one, could it have been made to include only the plants with the habit of 8. pteroneura, has been abandoned by Mr. Bentham in his forthcoming revision of the order Composite for the Genera Plantarum. Drscr. Quite smooth, glaucous, glabrous. Sfems four to eight feet high, lax, suberect; branches inarticulate, except at the ramifications, cylindric, pale green, half to three-quar- ters of an inch in diameter, nearly straight, obtuse, quite smooth except for the three longitudinal ridges that run down — the surface from the small transversely oblong distant leaf- scars. Leaves only developed on the very young shoots, elliptic or lanceolate, acute or mucronate, green, nerveless, a quarter to three-quarters of an inch long. Heads solitary, or two or three at the tips of the branchlets, erect, cylindric, scarcely three-quarters of an inch long; contracted in the middle, with a few filiform bracts at the base; peduncles very stout, longer than the involucre, swollen upwards and gradually passing into the base ef the involucre. Jnvolucral scales twelve to fifteen, narrow-linear, convex at the back, so close placed as to appear connate by their margins nearly to the tips, which are scarcely recurved and acumi- nate, green, brownish-red about the middle. Receptacle pitted. Flowers about thirty, pale straw-coloured, much longer than the involucre, all spreading. Corolla-tube narrow, slender; seg- ments very short, obtuse. Sfyle-arms long, with conic tips. Pappus hairs very slender, white, much shorter than the corolla. Achene \inear, smooth.—/. D. H.

Liniacem.—Tribe, ALINE ®, Genus Knipuoria, Mench ; (Endl. Gen. Plant., p. 148). Kwirnoria caulescens ; trunco erecto cylindraceo, foliis glaucis longissime subulato-ensiformibus ab ima basi ad apicem triquetrum sensim atte- nuatis dorso alato-carinatis, marginibus et carina argute serrulatis, scapo bracteolis parvis sparsis subulatis, racemo brevi fusiformi acuto, peri- anthii recti 13-pollicaris lobis brevibus obtusis, filamentis longe ex- sertis subequalibus, ovario obovoideo, Knipnorta caulescens, Baker mss. in Hort. Kew et Wilson Saunders. The accompanying figure is taken from a drawing made by my friend, W. Wilson Saunders, Esq., F.R.S., who flowered this fine species of Kniphofia in his garden at Reigate, in June of the present year. It differs from all other species known to me, in the distinctly caulescent habit, in this respect approaching the arboreous Cape Aloes, amongst which Linnzus included the genus to which it belongs. From the well-known X. Uvaria this species further differs in its small size, very glaucous habit, short racemes, much smaller less curved flowers, longer more exserted subequal filaments, and obovoid ovary. K. caulescens is a native of South Africa, where it was detected by Mr. Cooper, when collecting for Mr. W. Saun- ders in the Storm Bergen mountains, which bound the Albany district on the south, and border on British Caffraria; though a sufficiently striking species, it will never re- place the gorgeous K. Uvaria as an ornamental border-plant, even if it is as hardy, which is very doubtful; as yet it has ‘not been tried out of doors that I am aware of. JANUARY Isr, 1872. A dozen species of this fine genus are known to me; they are spread throughout Eastern and Southern Africa from Abyssinia to the Cape district; severval of them are said to grow in swamps, which is however not likely to be the case with the caulescent species. Col. Grant found one (when with Capt. Speke) in Tropical Africa, which he describes as a great ornament to the swamps and having a powerful honied smell, too sweet to be agreeable. Descr. Trunk, in garden specimens six to ten inches high, as thick as the thumb in our specimen, with short fleshy roots. Leaves rather soft, very glaucous, spreading and re- curved, two feet long, two and a half inches to two and three- quarters broad at the base, from which they are gradually narrowed to the fine triquetrous tip; keel acute, winged in the later produced leaves, margin and keel serrulate ; veins about fifty, obscure; upper surface concave. Scape six to ten inches high, stout, erect, green, with many scattered subulate bracts. Aaceme five to seven inches long, stout, spindle-shaped. Flowers pendulous, very dense and numerous, concealing the small subulate bracts ; pedicels one quarter inch long. Perianth nearly one inch long, straight, nearly equal, base rounded, deep blood-red when young, yellow after ex- pansion ; lobes small, obtuse. Stamens more than half as long again as the perianth, straight, nearly equal; anthers small, yellow. Ovary ovoid.—J. D. H.

A beautiful Andean Sage, belonging to the great group of Calosphace, which comprises most of the species of that im- mense European and American genus. It is a native of New Grenada, and was introduced into Europe first by M. Von Warscewicz, who sent seeds from Bolivia to M. Van Houtte, which flowered at Ghent in 1856, and from which the drawing cited above was published as S. boliviana. More recently Mr. Anderson Henry received seeds from Prof. Jame- son of Quito, and raised plants, one of which being sent to the Royal Gardens, flowered in 1862, and is here figured. Descr. A tall branched shrub, with herbaceous branches, more or less clothed with a pale hoary pubescence, most conspicuous when dry. Sfems four-angled, with concave faces, angles obtuse. Leaves very variable in size, four to ten — inches long, three to five inches broad, long-petioled, ovate- — cordate, crenate, acute or acuminate, puberulous on the upper JANUARY Ist, 1872. surface, hoary beneath; veins very numerous, especially towards the base of the leaf, hoary on the upper surface; petiole two to five inches long. Panicle a foot or more long, pyramidal, leafless, ebracteate, densely studded with glan- dular viscid hairs ; branches ascending ; whorls rather distant, 4 to 8-flowered, pedicels one quarter to halfinch long. lowers horizontal or ascending, one inch long.

Collections of Aroids are hence pretty nearly confined to Royal Establishments and Botanic Gardens. When grouped as they are in the Aroid House at Kew, they serve more than perhaps any other family of the vegetable kingdom, to convey some just idea of the rich luxuriance, strange and varied forms, deep hues,and glossy ever- green character of a tropical jungle. Second only to Kew is, (and has been from the days of its late Director, Dr. Schott) the Magnificent Aroid Houses of the Imperial Palace of Schen- brunn near Vienna, whence, indeed, Kew derived many of its treasures. Upwards of one hundred and thirty species of Philodendron are described in Schott’s “ Monograph of Aroidez, FEBRUARY Ist, 1872. 7 many of them indeed imperfectly, but all differing so materially from this, that I have no hesitation in describing it as new; it is further one of the few stemless species, and is con- spicuous for the sprinkling of blood-coloured spots on the spathe. It flowered in May, 1871, and was, we believe, sent from the Blumenau Gardens in South Brazil by Victor Geertner, in 1868. Descr. Stem none, or a short stock, clothed with brown fibrous sheaths that embrace the bases of the petioles. Petzole two and a half to three feet long, swollen at the base, cylindric except for about a quarter of the circumference, which is concave, with obtuse, raised edges. Blade of the leaf two feet long, broadly sagittate-ovate, bright-green and glossy, pinnatifid half-way to the middle; lobes regular, upeurved, linear, obtuse, rather broader than the obtuse intervening sinus; auricles (or posterior lobes) about one quarter as long as the blade, approximate or touching, with a narrow obtuse included sinus, the nerve marginal on the sinus, outer side cut like the rest of the blade into four or five lobes ; cost of the lobes very strong, rounded ; nerves slender, oblique, anastomosing within the margin. Spathes crowded, almost sessile, five to six inches long, white sprinkled with blood-red ; tube greenish, rather narrowly obovoid, one and a half to one and three-quarters of an inch in diameter ; blade longer, oblong, boat-shaped, abruptly acuminate, margins hardly reflexed. Spadix as long as the spathe, female portion three inches long, conical, three-quarters of an inch in diameter at the base, which is obliquely adnate to the spathe; male portion about twice as long, obtuse, pale dirty yellow.

Orchid. p. 17, t. vii. f. L—11; Walp. Ann. vol. vi. p. 679. Nearly a dozen species of the genus Zrichopilia have been described by Reichenbach f. in Walper’s Repertorium, all of them natives of Equatorial America, and limited to the area comprised between Mexico, Caraccas, and Peru, where they in- habit humid forests at moderate elevations; the species vary a good deal in habit, and in the form of the leaf, but are otherwise pretty well characterized by the celebrated Orchido- logist above mentioned. 7. hymenantha is perhaps the most delicate in the colour and texture of the flowers of any species of the genus ; it was first described in 1854 from the celebrated collection of Consul Schiller at Hamburgh, and has since then been cultivated in several collections. The drawing here given is from a beautiful specimen communi- cated by Messrs. Veitch. Descr. Rootstock short.

It was also found in the straits of Corea by Wilford when collecting for the Royal Gardens in 1859, and in the Loo-Choo Islands by the United States North Pacific Exploring Expedition in 1854, and is abundant in Eastern Bengal, from the Himalayas, the Khasia Mountains, Chittagong, &c. to Penang. Itis curious that so well-known and widely diffused a plant should not have been described in Thunberg’s “ Flora of Japan,” or in the earlier work of Kampfer. Siebold gives its native name as Tsisjano-ki, and Oldham, who introduced the plant into Kew, as Naats“gi. The young shoots of this and other species of Styraw are much infested by a gall-producing insect, that transforms the young leaves into incurved club-shaped bodies covered with FEBRUARY Ist, 1872. stellate down, and which form rosettes on the branches of a singular appearance. The same occurs on Himalayan and Khasian specimens, which bear another gall that is branched like a stag’s horn, and resembles somewhat that which occurs on the Himalayan R/ws, and is imported and used in tanning. The plant from which the accompanying drawing was taken, flowered in the Temperate House of the Royal Gardens _ in June, 1871. Drsor. A large shrub or small spreading tree; branches slender, drooping, glabrous, the youngest sprinkled with minute stellate down, as are the young leaves and calyces.

This is the second species of Aphelandra which has been introduced within the last few years by the Messrs. Veitch, from Guayaquil, the other being the far more showy A. nitens, figured at Tab. 5741 of this work. As a species, the present is more nearly allied to 4. aurantiaca, Lindl. (Tab. nost. 4224), which differs in the orange-red flowers, narrower lateral lobes of the lower lip, and long bracteoles nearly equalling the calyx. The Aphelandras, like other Acanthacee, are plants of easy cultivation with those who will pay ordinary attention to the requirements of their class, by giving them a proper rest, while their neat habit, showy colours, and protracted period of flowering render them admirably adapted for the shelf of a hothouse. As it is, of the ten or twelve species that have been introduced into England, few survive in cultivation, chiefly owing to the indiscriminate use of the watering-pot. Drscr.

The similarity of this plant to the Dberidella rotundifoha, figured at Tab. 5749 of this work, is very manifest, and is a strong argument for reducing the genus Jberidella to dithio- nema, as has indeed been done of late by M. Boissier, in his “Flora Orientalis ;” the difference between them hes chiefly in the capsule, which is broadly winged in dthionema, and scarcely winged in Jéberidella. a 4. coridifolium is a native of rocky mountains in the East, having been originally found by Labillardiere upon Mount Lebanon, where it has subsequently been gathered, between the village of Eden and the famous cedar grove, by Boissier ; it has also been found in the Cilician Taurus by Kotschy, who probably introduced it into the Botanic Garden of Vienna, whence it was sent by M.

Comparatively very few species of the most curious genus Stylidium have been cultivated in England, though it is one of the largest in Australia, numbering in Bentham’s Flora of that continent, eighty-three species; of these many are very beautiful plants, and all remarkable for the irritability of the column of the style and stamens, which remains curved down from the perianth till touched at the bend, when it Springs up with elastic force, scattering the pollen; an arrangement doubtless intended to secure cross-impregnation, by causing the insects which may visit one flower to carry its pollen to another. Altogether some twenty species have been in cultivation at one time and another, of which ten have been figured in this work, but I very much doubt whether more than three or four could now be mustered in the United Kingdom, so little interest is shown by horticul- turists in any but showy plants. 3 FEBRUARY Ist, 1872.

Amongst the striking objects in the Great Temperate House at Kew, none has of late attracted more notice than the gigantic specimen of Zbdea barbara, or as it is there called (from its affinity to our British Osmunda), the Australian Fern Royal, sent by Baron Von Mueller, from the Victorian Alps, in 1869. Huge specimens of this plant had previously — been sent to Europe from Australia, and, after seeing — four such exhibited at the St. Petersburg Horticultural Exhibition in 1869, I wrote to my friend the Baron, and begged him to procure for us the largest specimen he could ; which with his wonted promptitude and liberality, he did at MARCH Ist, 1872. once, s6 that before the end of that same year, Kew was possessed of the finest specimen in Europe,. transmitted moreover free of cost for transport or voyage. None of these St. Petersburg examples equalled that here figured in bulk or weight; and owing to defective treatment, their foliage was so starved, that they looked rather like grotesque vegetable monsters, than the truly noble plants 4 which they would have been, had their natural wants been supplied. As with almost all other Ferns, Zodea barbara likes humidity and shade, and it is under these conditions that, at the bottom of the dark gorges of the Australian Alps, it attains its gigantic bulk and luxuriant crown of fronds, growing out of steep banks, with its base often washed by a torrent. Stuck upright in a tub, as usually planted in our greenhouses, the roots which clothe the huge caudex soon dry, and the fronds are imperfectly developed; but when set upon a Shallow vessel of water, propped up between stones in front, a mass of earth kept in place by cask-staves behind, and when stones, earth, and caudex are clothed with Lycopodium, it sends out fountains of fronds throughout the year. The specimen here figured arrived at Kew in the autumn of 1869, and weighed in its dry state, when taken out of the box of sawdust in which it was packed, exactly fifteen cwt.; it then had not a frond developed on it, now it has some 30 crowns, and in all just 160 fronds, averaging five feet in length. The reduced figure given on the accom- panying plate, being taken from above the level of the plant, gives no idea of its stateliness and effect. Still larger specimens than the above have been since sent to Europe by Baron Von Mueller, of which one, presented by him to Mr. J. Booth, of Flottbeck, Hamburgh, weighed one ton three ewt., high, seven feet nine inches wide, and three feet three inches in its smaller diameter. The genus Zbdea takes the place of Osmunda, in the Southern hemisphere, and was united with it by R. Brown, ast think with much reason. 7. darbara is a native of Tasmania, S. and E. Australia, and South Africa, in which latter country, however, it does not, in so far as I know, attain the dimensions that it does in Australia. Linneus named it Acrostichum barbarum, because of its African origin ; but it is not a native of Barbary.—J. D.

This pretty plant does not accord with any genus as at present described, but cannot I think be excluded from Bulbine, alarge genus of South African plants, from which ‘its beardless stamens alone distinguish it. The only alternative is to place it in Bulbinella, from which it differs in the numerous (not twin) ovules, and filaments all equal in length; or in my genus Chrysobactron (Tab. Nost., 4062),which has also twin ovules, and which differs from Bu/éine in no important par- ticular. Upon the whole I am disposed to think that the best plan would be to retain the Linnean genus Anthericum, which he substituted for Bulbine, and to include in it species with glabrous and bearded filaments ; subdividing it primarily into those with twin ovules in each cell (Bulbine including Chrysobactron), and species with several ovules in each cell, which is again divisible into those with bearded and those with beardless filaments. Endlicher (Gen. Pl., 148) has indeed included Bulbine under Anthericum, but his character of the latter genus excludes the 2-ovuled spevies, and attributes to it a declinate style. Bulbine Mackenii was transmitted from Natal by Mr. McKen, the energetic superintendent of the D’Urban Botanic MARCH Ist, 1872. sift aaa al Gardens ; it flowered in the Royal Gardens in July of last year, _ and of the previous one, the flowers opening after mid-day.

Very closely allied to, but much less handsome than ¥. cinnabarinum, which was figured last year (Tab. 5921) in this work, and differing remarkably in the form of the leaves, which, curiously enough, are variegated in both species in our stoves, suggesting a common origin for this sport or disease. It is a native of the hilly regions of N.E. Bengal, where it was discovered by a collector of the Calcutta garden, Mr. F. de Silva, and well figured by Wallich as Justicia padlatifera, from specimens introduced into the Calcutta Botanic Garden in 1825. Singularly enough, no specimens Occur under this name in Wallich’s Herbarium, where, how- ever, this species is abundantly represented under &. crenu- MARCH Ist, 1872, latum, a rather common Indian hill plant, which I gathered at Chittagong, and which extends thence to Java, and is also found in Ceylon and the Madras Peninsula. The history of Z. crenulatum* is obscure ; it first appearsin the Botanical Register (Tab.'879) in 1825, as a ms. name of Wallich’s, applied to a plant from Silhet, which he sent to the Horticultural Garden in 1824, the very year in which he received Ff. palatiferum in the Calcutta Garden; but the Register figure is totally unlike the plant subsequently described by Nees as &. crenulatum (Wall. Pl. As. Rar., i. 107), in having a small regular corolla with acute lobes, and is probably an Asystasia in a starved state. 'T. Anderson, in his enumeration of the East Indian Acanthacee (Journ. Linn. Soc., v. ix. p. 524), throws no light on the subject. Under these circumstances it appears to me best to retain the name palatiferum, as being that which Wallich applied to this plant, which he figures and describes well. It is further to be observed that Nees errs in putting £ ciana- barinum and this plant (his erenulatum) in the section of the genus with the corolla limb equal, it being strongly bilabiate in both; in so doing he has followed the Register plate, and not the specimens he has so named. The subject of our plate was sent to Kew from the Cal- cutta Botanic Garden, and flowered in April of last year ; it belongs to the var. glandulosum, in which the glandular pubescence of the inflorescence extends to the upper branches, and which inhabits the Malayan Peninsula.

Certainly the handsomest Groundsel hitherto discovered, — and truly designated by its original describers, and this from dried specimens that had lost all their beauty, as “a splendid plant, one to four feet high, with flowers two inches and more in diameter, the ray purple.” It was discovered at the foot of the Sugar-Loaf Mountain, near Maldonado, and at Aldoa, west of Portalegre, in S. Brazil, by that indefatigable traveller and gardener, Tweedie, nearly forty years ago, and there are also specimens in the Hookerian Herbarium, gathered on grassy hills near Maldonado by Mr. Fox, late British Minister in Uraguay. : The introducer of the plant into England is Mr. J. Tyerman, formerly of Kew, and for many years the skilful and energetic Superintendent of the Liverpool Gardens ; now of Penlee Tregooney, in Cornwall, where he raised it from seed sent from Buenos Ayres, flowered it in November 1871, and sent it to Kew for determination.

A stove shrub, imported by Mr. Linden from Para, very attractive from its climbing habit, abundance of snow-white. sweet-smelling blossoms, and bright glossy foliage. Though belonging to the same Natural Order as the Violet, and closely connected with that genus, its habit and the form of its flower more resemble those of the racemose Indian Balsams. The curious twist of the spur has been observed by Martius alone in his careful description of this plant. It is a most variable species, and I believe that all the so-called species the genus contains, and which are hitherto described, are referable to APRIL 1st, 1872. one, which extends from the Amazon (which it ascends to the junction of the Rio Negro), to Venezuela, Columbia, Guate- mala, and St. Vincent ; but which, curiously enough, has not been detected in Trinidad. The C. albiflora of the Morist is clearly the same, with the articulation of the pedicels and bracteoles omitted by the artist. The specimen here figured flowered in January of the present year in Mr. Bull’s © establishment at Chelsea. Descr. A slender, glabrous climber; branches terete, spotted with white. eaves alternate, two to five inches long, elliptic-oblong or ovate, or orbicular, obtuse or acute, quite entire or serrulate, bright grassy-green, paler beneath, nerves reticulate; petiole one quarter to half an inch long.

Botsopuytium lemniscatum ; pseudobulbis depresso-globosis grosse tuber- culatis, foliis 2-3 e basi pseudobulbi enatis elliptico-lanceolatis, scapo apice cernuo gracillimo supra medium vagina longissima subinflata aucto, spica brevi pendula, floribus parvulis imbricatis, sepalis sub- equalibus supra medium connatis ovato-rotundatis obtusis dorso infra apicem appendice pendula gracillima clavata e lamellis 10 longitudina- libus crenatis constante auctis, petalis minutis lineari-oblongis obtusis columne utrinque rostrate appressis, labello brevi incluso lingueeformi crasso obtuso convexo levi. Bo.zoruyiium lemniscatum, Parish mss. A more singular little gem of an Orchid than this cannot well be imagined. Its curious glossy tubercled pseudobulbs, its capillary scape with the long inflated upper sheath, its pendulous spike of glistening minute flowers, and above all, its slender appendages that hang one from the back of each Sepal, and which are as curious in structure as beautiful in colouring, together seem to mark it as the type of a new genus. This I should have named JLemniscoa Parishii, had not its discoverer seen reason to refer it to the hetero- geneous genus Bolbophyllum, to which it 1s certainly very closely allied, but which appears to me to want a redistribu- tion of its species. The elaborate structure of the appendages of the sepals deserves special notice. Each consists of a narrow club-shaped very flaccid body, three to four times as long as the flower, and is gradually narrowed into a fili- form pedicel. On a superficial examination it appears to be 10-sided, but on a transverse section is proved to consist of a APRIL Ist, 1872. capillary axis, from which radiate ten longitudinal crenate undulate plates, of equal breadth and extreme delicacy. The whole organ is not more than one-sixth to one-fourth of an inch long, of a brilliant red-purple colour transversely banded with white. These appendages suggested the very appro- priate name of /emniscatum (from lemniscus, a coloured ribbon). Of their possible use I can form no conception; they fall off as the flower expands. The Rev. C. Parish discovered this plant flowering on an old shingle roof at Zwakabin, in Moulmein, in November, 1868, and sent plants to the Royal Gardens in 1870, which flowered in July of the present year. Descr. Pseudobulbs a half to three-quarters of an inch in diameter, depressed, tubercled. eaves in a tuft of three or four, springing from the base of the pseudobulb, one and a half to two inches long, elliptic-lanceolate, acute, deciduous. — Scape also from the base of the pseudobulb, four to six inches high, capillary, with two or three short sheaths below the middle, and one very long slender slightly inflated one above it. Spike pendulous from the curved tip of the scape, three-quarters of an inch long, oblong; bracts small, sub- ulate. Flowers one-twelfth to one-tenth of an inch long, crowded, imbricate. Ovary short.

Maspevatuia ignea; Reichd. fil. in Gardener's Chronicle, Nov. 1871, p. 1482. _ Avery near ally of MW. Veitchiana (Tab. nost. 5739), and of as vivid a colour, but differing remarkably in the form of the leaf, which is also long-petioled, and in the shape of the Sepals and their disposition and curvature. According to Reichenbach, fil. (who quotes Mr. Day for the information), it was originally imported from New Grenada in March, 1870, and sold in Stevens’s sale-rooms. That learned Or- chidologist describes it from specimens that flowered in Messrs. Day’s, Branteghem’s, and Veitch’s collections. That figured here is from a large flowered form which flowered in Mr. Bull’s establishment in February of the present year. The colour, though not so deep as that of the Veitchiana, is quite as vivid, and more resembles that of cinnabar, or, as Reichenbach says, a “dazzling scarlet mixed with orange- scarlet, too dazzling to look at long.” It thus suggests a transition from the red heat of Veitchiana to a white heat. As in the latter species, this lustre—or water, as a jeweller would term it—is due to the refractive power of the fluid APRIL Ist, 1872. contained in the superficial bladdery cells of the sepals, and is — perhaps unsurpassed for brilliancy in the vegetable kingdom. Dzscr. Stems densely tufted, rigid, erect, sheathed at the base, each bearing a solitary leaf and flower. Leaf elliptic or elliptic-obovate, obtuse or notched, very coriaceous, bright deep green, pale beneath, blade three inches long, narrowed into a channelled petiole one to one and a half inches long. Scape slender, rigid, clothed at intervals with truncate sheaths, of which the uppermost is one inch long, lower somewhat spathaceous, compressed, and reaching nearly to the ovary. Flower one and a half to two inches long from the base of the ovary to the tips of the sepals, horizontal and decurved. Ovary one-third inch long. Sepals united at the base into a curved gibbous tube, half inch long by two-thirds inch in diameter, pale orange-red outside, bright cinnabar-red inside ; upper suddenly contracted from a triangular ovate base to a long slender point, bent down into the fork between the lateral sepals, than which it is rather shorter; lateral sepals elliptic-oblong, acute, rather obliquely incurved, convex above with recurved margins, 3-nerved. Pedals very small, wholly included, appressed to the sides of the column, linear-oblong, obtuse, base auricled in front, white, with a faint purple streak. Lip equalling the petals, included, linear-cblong, obtuse, recurved, cordate at the base, white, with a pale purple blush. Co/wmn erect, margins not winged.—J. D. #.

One of the earliest-known species of the curious genus to which it belongs, introduced into England by Masson, a col- lector for Kew, though it nowhere appears in the first or second editions of the Hortus Kewensis. Masson who first described it, in 1796, states that it flowered in his garden at the Cape of Good Hope in 1792, and in the Royal Gardens, Kew, in 1797. The said Francis Masson was a gardener at Kew, and was, at the instigation of Sir Joseph Banks, sent to the Cape, to collect live plants for the King (George Tit.) : he left England in 1772, and remained in South Africa till 1775, when he returned on leave to England, and spent his vacation in publishing the beautiful drawings he had made of Stapelias in a small folio work, dedicated to the King, with figures and descriptions of forty-one species, all new to science, (there having been but two previously published from that country) and collected in the Karroo country chiefly by him- self. In 1786 he returned to the Cape, and spent ten _more years in collecting for Kew. Close upon ninety species of Stapelia are described in Decaisne’s monograph of the genus, APRIL Ist, 1872. in De Candolle’s Prodromus, published in 1844, since which time many more have been discovered, but few figured. In 1811, forty-four species were cultivated at Kew, where there are now about thirty. St. sororia varies much in robustness, size of flower, and in the number and extent of yellow ridges on the petals. Descr. Pale green, glabrous. Sfems six to ten inches high, with erect or horizontal branches one-third to two-thirds of an inch in diameter, rather depressed or channelled between the angles, which are toothed at intervals of about one-third to two-thirds of an inch, the teeth are soft and incurved. Peduncles solitary or twin, from the young shoots at the bases of the branches, decurved, with ascending tips, three to four inches long. Flower three to four and a half inches in diameter. Calyz-lobes triangular-ovate, acuminate. Corolla clothed on the surface and margins with long hairs, which are very dense towards the throat; lobes five, ovate, acumi- nate, transversely rugose, dark vinous purple, the folds towards the base bright orange-yellow.

ARIS EMA speciosum, Martius in Flora 1831, p. 458; Schott Prodr. Syst. Aroid., p. 27. The moist forests of the temperate regions of the Himalaya abound in large, and even gigantic species of terrestrial Aroids, chiefly belonging to the genus Arisema; of these, some twenty inhabit the provinces of Nepal and Sikkim, flowering in the spring, and exciting the attention of the most careless ob- server by their brilliant colouring in some cases, and by their curious forms in all. ‘Two were figured in last year’s volume of the Magazine (4. curvatum, Tab. 5931, and A. concinnum, Tab. 5914), both sent by Mr. Gammie (formerly of Kew, and now superintendent of the Sikkim Cinchona Plantations). To this energetic officer we owe the introduction of several more, and amongst them, of that here figured, which flowered in the Royal Gardens in March of the present year. Un- fortunately, the genus is diccious, and no opportunity has presented itself of fertilizing the females, which alone have appeared. The tubers may, however, be kept in a cold frame throughout the winter, like those of any other plant of similar habits and constitution. The wonderful flexuous tail to the spadix, which I have MAY Ist, 1872. usually found lying on the ground, is the most striking feature of this and some closely allied species. Of its use, only a guess has been hazarded—that it may lead wingless insects into the spathe, and so to the stamens in one case, and to the ovaries in another, and thus effect the fertiliza- tion of the latter. 3 : The great tubers are, as of allied species, used for food in times of famine, after maceration and fermentation to dissipate the acrid poisonous principle which they contain. Drscr. Zuder the size of a large potato. Leaf solitary ; petiole sheathed at the base, dirty green mottled with brown, as thick as the thumb; leaflets three, petiolulate, six to eight inches long, broadly cordate ovate, long-acuminate, strongly nerved, deep green above with a blood-red edge, pale beneath; petiolules half to two-thirds of an inch long, laterally com- pressed, with blood-red edges and streaked sides. Peduncle lateral, two to three inches long, paler than the petiole and much more slender. Spathe five to six inches long; lower convolute portion cylindric, upper elliptic-ovate concave, with an acuminate recurved tip, deep purple inside, striped — with white, greenish or paler purple outside. Spadiz cylindric, contracted below into a short stipes, tip produced into a twisted and flexuous filiform tip, which is twenty inches long. Ovaries occupying about one to one and a half inches of the spadix, flagon-shaped or ovoid ; stigma sessile, discoid; ovules 3, basal, erect.—./. D.

A not uncommon New Zealand shrub, found throughout the two main islands, and, like its shrubby compatriots, varying excessively in stature, foliage, and colour of flower ; apparently passing at one time into the still more common V. salicifolia, and at others into the rarer V. macrocarpa and ligustrifolia, Tt is best distinguished from both these latter by the long slender racemes, short obtuse calyx-lobes and small fruit. I have little doubt but that these and other New Zealand species hybridize extensively in their own country, and that when they are more copiously introduced into this, the difficulty of naming them will prove insuperable. The form of parvifolia here figured is that described by A. Richard as V. angustifolia, and was procured from the Royal Botanic Gardens of Edinburgh under the name of linarifolia 10 MAY Ist, 1872. 1870; it flowered in the temperate house at Kew in July of 1871, and is a remarkably graceful greenhouse plant, of easy cultivation. 8 Descr.

Linden, of Brussels, but not, as far as I am aware, in this country (see Reichb. f. in Gard. Chron., 1869). ; Since that period a considerable number of species have been discovered and described, most of them presenting the curious antenna-like form of dorsal sepal and petals, and all inhabiting the mountains of Venezuela and the Andes, from Guatemala to New Granada. : R. elegans inhabits mossy tree trunks at elevations of 5-6000 feet in the province of Caraccas, whence there are ied specimens in the Hookerian Herbarium, collected near the colony of Tovar, by Fendler.

Deyprosivy amethystoglossum, Reichb. f. in Gard. Chron. 1872, p. 109. This remarkable Dendrobe presents the contrast of great beauty of inflorescence and flower, with a singularly ugly habit of growth. On the one hand, nothing can well be uglier than the thick, clumsy, slightly flexuous, naked stems, two to three feet long, that stick straight up from the tree- _ trunk it inhabits, and which further present, after flowering, the persistent naked remains of the old racemes, projecting right and left from the internodes; on the other, it is difficult to describe the ivory-whiteness of the sepals and petals, and the lucidity of the amethystine purple on the lip. D. amethystoglossum is a native of the Philippine Islands, whence it was imported by Messrs. Veitch, through their collector, G. Wallis, amongst a lot of D. taurinum ; it flowered in February last, presenting three racemes on the stem at once. Descr. Stems fascicled, two to three feet high, stout, one inch in diameter, slightly flexuous, dirty green, obscurely channelled, tapering to the apex ; internodes about two inches long, clothed with appressed deciduous sheaths, Leaves not MAY Isr, 1872. seen. Lacemes three to five inches long, ovoid-oblong, obtuse, pendulous from alternate nodes, shortly peduncled, very many and dense-flowered, the flowers imbricating before full expansion; peduncle and rachis green; bracts minute; pedicels half an inch long. Yowers one and a half inches in diameter, ivory-white except the amethystine purple end of the limb of the lip. Sepals and petals nearly equal, obovate-oblong, acute, spreading. Jip cymbiform, elongate linear-spathulate in outline, with a short claw, tip apiculate, margins incurved, except toward the apex; base beyond the claw with a fleshy triangular appendage, that points back- wards.

A very elegant little Fritillary, apparently common in the mountains of Georgia and Armenia, and extending thence to those of the Taurus in Asia Minor. It has also been de- scribed as a native of Greece and Siberia, and even of the Pyrenees, under the names of F. persica 8 pyrenaica, Sibth., F. racemosa, Miller, &c., but without living specimens to com- pare, I dare not venture to unite these species of so difficult agenus. Klatt refers F. obliqua, Gawler (Bot. Mag., tab. 857), to the same series, but that is a racemose species with narrow twisted leaves and violet coloured flowers,and has, I apprehend, nothing to do with this, and is probably a form of F. persica (Bot. Mag., tab. 1537.) ; As a species F. tulipifolia is remarkable for its glaucous blue hue, and the singular colour of the flowers, which re- semble a tulip in shape, and have a chalky appearance outside. According to native specimens, it varies greatly in stature and in the size of all its parts. | MAY Ist, 1872, Our specimen flowered in the open border at Kew in — March of the present year. Duscr. Very glaucous throughout, except the inner sur- face of the perianth-segments. Stem, in our specimens, four to six inches high (two to eight in native ones), slender, leaf- less below, but there clothed with appressed sheaths. Leaves three to four on each stem, one and a half to two and a half inches long, elliptic or elliptic-lanceolate, subacute, concave, sessile, straight, sheath very short,nerveless, pale green ; upper linear lanceolate. Flower solitary, very variable in size, three- quarters to one and a quarter inches long, nodding, exactly tulip-shaped. Perianth-segments subequal, oblong, obtuse or obtusely apiculate, rusty brown purple within, not tessel- lated; the outer dark glaucous blue streaked with the same purple outside; the inner with a broad glaucous blue band down the back ; nectary a linear-oblong green gland. Sta- mens erect, filaments slender, twice as long as the narrow linear obtuse yellow anthers.

Chron. 1869, p. 1206. ea By far the stateliest species of the genus hitherto dis- covered, and an exceedingly handsome plant, though by no means remarkable either for colour or form, as compared with some of its congeners. Its three-celled ovary places it in the genus Selenipedium of Reichenbach f.,and its habit in — close affinity with C. caricinwm, (Pearcii, Hort.: Tab. nost. 5466); to which genus (which we are disposed rather to regard as a subgenus,) also belong C. caudatum, Lindl., and seven other species enumerated by Reichenbach, all of them American. : ee C. longifolium was discovered by M. Warszewicz, in the Cordillera of Chiriqui, in Central America, at an elevation ot 5-8000ft, and introduced into Europe about ten years ago. The superb specimen here figured was exhibited at the Horti- cultural Society in January of the present year, by Mr. Bull, F.R.S., of Chelsea, and kindly by him placed at the disposal of the artist of the Botanical Magazine for figuring. JUNE Ist, 1872. Drscr.

A robust ornamental evergreen, which, like the subject of Tab. 5973, thrives admirably in the damp mild climate of the West of England, but is only suited for a greenhouse or Sheltered wall in the more Eastern counties. Living Specimens in full flower were communicated by Dr. Wood- man of the Exminster Nurseries (Messrs. Lucombe, Pince and Co.) in February of the present year, where it formed a luxuriant shrub three feet high, with deep green foliage starred with blood-red racemes of flowers. It was discovered by A. Cunningham on the north bank of Cox’s River, N. S. Wales, in 1822, along with G@. su/phurea and G. canescens (Tab. nost. 3185), and was probably in- troduced into England shortly afterwards, for a weak and Starved specimen is figured in Loddige’s Botanical Cabinet as having flowered in the celebrated Hackney Nurseries. Descr. An erect shrub, five to six feet high; branches short, erect, tomentose.

A very singular Aroid, belonging to a small Brazilian genus never previously introduced into Europe, for tubers of which the Royal Gardens are indebted to D. Hanbury, F.HS., who, received them from Senor Correa de Melho, an inde- fatigable naturalist of Rio de Janeiro. ‘I'wo specimens flowered simultaneously in the propagating pit at Kew, in February of the present year, of which one bore a flowering spike alone, the other both a flower and a leaf. Neither was so large as the specimen represented in the “ Flora Flumi- nensis,” which has, moreover, a more acute spathe produced further beyond the spadix. These two specimens further differed, in that one (bearing the name of var. porphyrosticta) had more purple in the spots of the petiole and scape; the other (var. chlorostica) had greener spots. These differences disappeared with age. The leaf of the latter was of a paler green, with broader closer-set segments. The colour of the petiole, scape, spathe, and male portion of the spadix are very curious and striking. JUNE Ist, 1872. Duscr. Tuber the size of a tolerable potato, oblate, smooth, brown, with many stout branching rootlets from the crown. Leaf one to two feet long, deep green, broadly ovate in out- line, pinnatifid ; two lower segments deflexed, deeply cut into three to five lanceolate acuminate lobes ; remaining segments four to six pairs, sessile, remote (contiguous in Vellozo’s figure), lanceolate, acuminate, irregularly sinuate-lobed or quite entire, broadly decurrent ; petiole six to twelve inches long, cylindric, whitish, closely striate or irrorate, with short vertical black-purple streaks, that are obliquely confluent above. Scape similar to the petiole. Spathe two to four inches long, erect, cylindric, acute, with a narrow opening above and recurved edges, deep green externally and speckled with brown, reticulate internally.

This is one of the beautiful Daisy-trees of the Australian colonies, a genus of plants many of which would thrive well and form great ornaments in the gardens of the mild part of Western England, and some of which stood for several winters in sheltered water at Kew, but were killed during recent cold winters. | The present species forms a fine bush in the Scilly Isles, where it was introduced by Augustus Smith, Esq., into his garden at Tresco Abbey, St. Mary’s, it is believed from Kew, a good many years ago. I had the pleasure of visiting these gardens about fifteen years ago, with my late friends Prof. Harvey, of Dublin, and Veitch (the grandfather and founder of the firm), when we were al] astonished and delighted with the luxuriance and variety, especially of the Cape and Australian JUNE lst, 1872. vegetation they displayed. Since that period, Mr. Smith has added many hundred species to his collection, and I have the pleasure of receiving every early spring a hamper of cut flowers of rare (with us) greenhouse plants cultivated in the open air, when the snowdrop and the winter-aconite are the only plants to be seen flowering in our open borders.

(Lab. nost. 1276), and so near to it specifically, that I doubt its proving more than a variety of that plant; its Principal distinctions from Klatt’s characters of serotinus, lie ithe margins and midrib of the leaf being perfectly smooth, in the fibrous coats of the bulb not being strongly reticulate, and in the pale yellow blotch at the throat of the perianth being Scarcely apparent. These are, however, all of them very vari- able, and indeed obscure characters; the amount of reticulation _ Of the coats of the bulb is‘an inconstant one ; in Gay’s beautiful unpublished drawings of C. serotinus in my possession, a Cross section of the leaf as magnified shows no scabridity, nor do I find any in authentic specimens of serotinus ; lastly, the yellow spot at the base of the outer perianth-segments of C. serotinus, though described by Klatt, is not visible in the Botanical Magazine figure, or in Gay’s drawings. Gay’s character, drawn from the insertion of leaf on the tuber, isa most obscure one. C. Clusii, Gay, is another form NOVEMBER Ist, 1872. of C. serotinus, also from Portugal, distinguished by its author by the white throat of the perianth, and the lower insertion of the petiole. It should be observed that both C. Clusii and C. Salzmanni are omitted in Klatt’s monograph; and that the figure of C. serotinus in the Botanical Magazine represents the tuber deprived of its coats. All three are probably western forms of C. longifforus, Raf., an Italian species that extends into Sicily and Dalmatia.

Sarcostemma:Brunonianum, Wight et Arn. Contrib, p. 59; Wight Ie. t. 1282; Dene. in DC. Prodr., vol. viii. p. 537. This very singular plant is a native of Ceylon, and is also common in arid jungles of the Madras Presidency, where it forms great masses, climbing over shrubs, tree-trunks and stones, 2abounding in an acid milky juice, and hence eaten by the : natives as a salad, and sucked by travellers to allay thirst, thus forming a remarkable exception to the usually poisonous — nature of the Asclepiadeous juices. Unfortunately it fre- quents the jungles in which the poisonous and acrid Luphor- bia Turiculli grows, and indeed it often spreads over that plant, whose leafless branches so closely resemble those of the Sarcostemma, that if care is not used one may be mistaken for the other, the consequences of which might be serious. Of a very closely allied species a curious use is made; bundles of its branches are cast into the wells from which sugar-cane fields are watered, together with a bag of salt, the result of which is that the white ant is expelled from the field. _ Sarcostemma Brunonianum grows freely in a pot in a warm greenhouse, where its branches hang down in masses NOVEMBER Ist, 1872. _ several feet long, and when covered with the deliciously sweet- scented white blossoms, have a very elegant appearance.

Baremania Burtii, Endres 5 Reichb. f. in Gard. Chron. 1872, p. 1099. ‘The genus Batemania, named by Lindley in 1835 after the - distinguished orchidologist James Bateman, F.H.S., consists of - _half-a-dozen species of tropical Eastern, South American, and ‘Spanish-Main plants, as enumerated by Reichenbach in the sixth volume of Walper’s “Annales.” Some of these had been long known, but previously referred in books or col- lections, some to Huntleya, some to Zygopetalum, and some to Galeottia. The species here figured is a native of Costa Rica, where it was discovered by M. Endres in 1867, and is re- garded by Reichenbach as very closely allied to B. meleagris, ‘Rechb. f. (Bonplandia, vol. iii. p. 217), a native of Brazil, but differing in the colour of the flower and form of the curious ciliated appendage on the claw of the lip. It isa magnificent Orchid, whether as regards the luxuriance of the foliage or the form and colour of the flower. I am indebted to Messrs. Veitch for the opportunity of figuring it their specimen was procured through W. Burnley Hume, Esq. ; 1 flowered in August of the present year. DECEMBER Ist, 1872.

Satvia (Plethiosphace) dichroa; glanduloso-pubescens, caule erecto 4-gono angulis incrassatis pilosis, foliis sinuato-crenatis inferioribus petiolatis ovato-oblongis obtusis pilosis, caulinis sessilibus oblongis obtusis, supremis seu floralibus parvis ovatis acuminatis, racemis simplicibus, rachi robusto, verticillastris paucifloris, floribus pedicellatis, calycibus obovato-campanulatis glandulosis, labio superiore 3-dentato dente medio minore, inferiore 2-fido lobis triangulari-subulatis porrectis, corolla calyce triplo longiore, tubo glabro non inflato intus annulo piloso instructo, labio superiore elongato compresso obtuso pubescente inferiore superiori subequilongo 8-lobo, lobo intermedio suborbiculari pendulo albo, lateralibus decurvis brevibus, connectivis elongatis antice breviter porrectis apicibus tumidis, coherentibus. A near ally of Salvia bicolor, Desf. (Tab. nost. 1774) and 8S. alyeriensis, Desf., the former a native of Northern Marocco, and the latter of Algiers; but very distinct from both in the form of the leaves, and from the latter in the much. greater size of the lower lip, which, as in S. bicolor, nearly _ equals the upper. Of the two it is very much nearest to _ 8. bicolor, and but for the very different form of the radical leaves, and the nature of their lobing, I should have been _ disposed to regard it as a variety of that plant; the radical and lower leaves of S. dicolor are deeply cordate sinuate- toothed and much cut, the teeth and lobes spreading ; the _ analogous leaves on S. dichroa are oblong, acute at the base, _ and irregularly cut at the margin into large obtuse lobules. that point towards the apex of the leaf. In the description of §. bicolor under Tab. 1774, it is stated that the under-lip, Which at its first expansion is snow-white, almost immediately ' DECEMBER Isr, 1872. begins to fade to rusty-brown, a change I have not observed in this species, but which may occur. Roots and leaves of this plant were collected by Mr. Maw at the base of the Greater Atlas, south of the city of Marocco, at about 2000 feet elevation below Tasmeroot, in May 1871, which flowered in his garden, at Broseley, in August of the present year. It is an exceedingly. handsome species, the colours much resembling those of Collinsia verna. Descr.

Leaves, radical petioled, six to eight inches long, oblong-ovate or ovate-lanceolate obtuse, narrowed into the petiole, obtusely and very irregular sinuate-serrate with rounded lobules, pubescent, lower cauline short-petioled ; upper sessile, oblong or elliptic-oblong; floral ovate, long acuminate, reflexed. Raceme a foot long and more, stout, obtuse, many-flowered ; false-whorls of two opposite fascicles of two to three pedicelled flowers, pedicels erect, half an inch . long. Calyx three-quarters of an inch long, subcampanulate, 2-lipped to the middle, glandular-pubescent, strongly ribbed, green; upper lip with three small teeth, the mid one smallest ; lower with two subulate lanceolate straight teeth..

Though maintained as a species by Koch in his valuable - revision of the genus Lilium, quoted above, and apparently by Duchartre also in his admirable observations on the genus, I think that no one can compare Lilium concolor and — sinicum, whether by figures or as specimens, without becom- ing convinced that Lindley’s original suspicions were grounded, and that Mr. Baker is right in regarding them as _ __ Specifically identical; though they may perhaps be grige ently distinguishable as varieties or forms. Not only “4 they come from the same country, but both are known only in ivati ith spotted and spotless flowers ; a between them is, that DECEMBER Ist, 1872. the perianth segments of Z. sinicum are less revolute than those of Z. concolor. | * The original Z. sivtcum was introduced into England early in the century (1806), from China, and is described as scentless, but very ornamental; the var. siaicum, which Mr. Baker does not consider to be entitled to rank even as a variety (in which I am almost disposed to agree), was im- ported also from China in 1850 by Mr. Fortune, though not for the first time; it having been introduced by the Horti- cultural Society as early as 1824. The specimen here figured was communicated by Messrs. Osborne and Sons, — with whom it flowered in June of the present year. It varies very much in stature, and we are informed that a very pretty small variety, about six inches high, has been exhibited by Mr. Bull at the Horticultural Society. Descr. Bulb scaly.

Uvaria Kirkii, Oliver Mss. It is seldom that the opportunity occurs in England of _ figuring plants of the large tropical family of Anonacee from a living plant, these being for the most part trees or branch- — ing shrubs, requiring room, great heat, and moisture; and having little to recommend them to horticulturists, they are banished from the stove in favour of handsome and freer flowering things. Uvaria Kirkii was discovered by Dr. Kirk, formerly the companion of Livingston during his second expedition into Central Africa, and now H.B.M. Vice-Consul at Zanzibar, from whence he has transmitted many valuable plants to the Royal Gardens, including the singular Zamiocu/cas figured at Tab. 5985 of this volume. About fifteen species of Uvaria are known from Africa, and many more from India. The _ present forms a low shrub of three to four feet high at Quiloa on the Zanzibar eoast, with very yellow green foliage, and large dingy yellow flowers. Seeds of it were transmitted to England by Dr. Kirk, in 1868, and the plant here figured flowered in October last. DECEMBER Ist, 1872. Descr.

A very curious species of Dendrobe, discovered by the indefatigable Mr. Parish in Moulmein, and communicated by him to the Royal Gardens in 1871, where it flowered. in March of the present year, and was examined by Professor Reichenbach, who has obligingly communicated the following note upon it, together with a diagnosis: “ Near D. euphlebium, Reichb. f. (Journ. Proc. Linn. Soc., 1859, p. 7), but widely — differing in the flattened stem and form of the lip. The re- markable character of the stem developes in this species as much as it does in D. crassinode (Tab. nost. 5766), but at a later period. The young stem is homomorphous, with wide leaf-sheaths ; as the stem gets older, the upper leaf-bearing internodes flatten, and lateral shoots appear, which root im- mediately.” ; Descr.

Native of Iropical Australia. Nat. Ord. CrcapEa&.—Tribe ZAMIEZ. Genus Bowens, Hook.; (Bot. Mag. t. 5398). BoweEnta spectabilis; amentis foemineis masculis multoties majoribus et crassioribus subsessilibus oblongo-globosis apice rotundatis, squamis sub-6-seriatis fere superpositis crassis transverse elongatis hexagonis peltatis vertice depresso rugoso, subtus utrinque 1-ovulatis, ovulo recto ellipsoideo apice mammillato, semina ovoideo-globosa, testa crasse crustacea, albumine duro, embryone albumine circiter triente breviore, radicula in filum contortissimum prelongum tenuissimum contracta, cotyledonibus 2 brevissimis. Bowenta spectabilis, Hook. l.c.; F. Muller, Fragm. Phyt. Austral. vol. v. pp. 171 and 215. The first account of this most remarkable plant, the only known Cycad with bipinnate fronds, was that given in this work in the year 1863, when the male cone alone was known. Since that period specimens have at various times been received from Mr. Hill, the energetic superintendent of the Brisbane Botanic Garden, and amongst them female plants, of which one flowered at Messrs. Veitch’s and another at Kew, during the present year. Unfortunately, no male flowers were procurable at the same time, so that there was no chance of fertilization ; the ripe seed has, however, been well described by F. Miiller, whose description I find to be correct. The tuberous stem of Bowenia has the property of remain- ing dormant for years, and resisting all excitements to growth. A small cylindrical specimen, about three inches by about two-thirds of an inch in diameter, received at Kew in the year 1864, and which arrived with a healthy leaf, soon lost it, and remained for four years leafless, making very little root, and developing no bud; it was plunged into strong DECEMBER 1st, 1872. bottom heat for months; and again kept moderately cool for as long ; it was kept dry at one time and copiously watered at another, but all to no purpose; at last it made a push and produced a fine frond, and subsequently a male cone,.- » with considerable rapidity. The largest specimen now at Kew has a frond five feet in diameter, with the individual pinnules four inches long ; its graceful, glossy foliage is very ornamental, and the plant is remarkably free from the attacks of insects. In some dried specimens there is a strong tendency in the leaflets to become laciniate at the apex. The ripe fruiting cone is very curious, and quite unlike any other Cycadeous fruits which I am acquainted with; it is about the size of a human fist, and . consists of about twenty broadly ellipsoid nuts, one inch in long diameter, adhering in pairs to the shrivelled scales, and these to the axis in a very irregular manner, the scales having - shrunk so much that the seeds are completely exposed, and point in various directions, seldom retaining their original position which is inwards or towards the axis. : Tn addition to the habitats already known for this plant, of Endeavour River, where it was discovered by Allan Cun- ningham, and Rockingham Bay, whence Hill sent it to England, and where it grows in company with Macrozamia Denisonii, Mueller enumerates those of bushy hills near the McKay River, and the summit of Mount McAllister ; he further observes that it differs from Zncephalartos only in the compound leaves, and he reduces Hucephalartos itself to a subgenus of Zamia—J.
