B. Ariza, Benth. Pl. Hartweg. p. 170. B. Princeps, Linden Catalogue, 1877, No. 98, p. 33. When for the first time a Brownea flowered in this country (in the Edinburgh Botanical Garden in 1842), it was said of it, “ Few things can exceed the elegance, or the richness of the colouring in the beautiful flowers of this shrub” (Graham in Bot. Mag. t. 3964), This applied to B. coccinea, now considered by far ‘‘ the poorest thing’’ of the genus that has hitherto been cultivated in England, its heads of flowers being little over two inches in diameter. It was succeeded by B. grandiceps (flowered in 1855), which was pronounced, “‘ Although far inferior in point of richness of colour of the flowers to B. coccinea, yet the quantity of flowers collected into an almost globose head nearly eight inches in diameter, gives this infinitely the advantage over that species” (Bot. Mag.t. 4839). Of B. Ariza, the third species that has flowered, it may truly be said, that it combines with the size of head of B. grandiceps the vivid colouring of B. coccinea. Brownea Ariza is a native of New Grenada, having been ~ discovered, about the year 1842, by the late Theodor Hart- weg, in forests of the province of Bogota, at an elevation of 1400 feet above the sea, where it is called the Ariza by the inhabitants; it was not however introduced by that traveller JANUARY Ist, 1880. into cultivation, though so stated by Paxton. The splendid specimen here figured was flowered by the late deeply- lamented Dr. Moore of Glasnevin, who was also the first to flower B. grandiceps. In a letter received with the plant from him in March of last year, he informed me that he re- ceived it from the Continent (presumably from Mr. Linden) under the name of B. Prinéeps; that it was then fourteen feet high, and flowered profusely every year. In another letter of later date he says, “ Although the individual bunches of flowers are rather smaller than those of its rival B. grandiceps, their brilliant colour far surpasses it. Both ~ are in flower here at present, B. grandiceps with upwards of fifty flowering bunches on it.” The Brownea Ariza of Paxton’s Flower Garden, vol. u. p. 59 (1851-2), copied in Lemaire’s “Jardin Fleuriste,” t. 1942, is a totally different plant from this, and apparently B. grandiceps. Desor. A tree thirty to forty feet high; branches gla- brous, and petiole and rachis of leaf covered with brown shining bark, bearing small scattered smooth warts.

A frequent inhabitant of the western temperate Himalaya, from Garwhal westward to Kashmir, at elevations of 5000 to 8000 feet, where it is one of the most ornamental of the herbaceous perennials from the delicacy of its azure blossoms sprinkled with pearly white, and the brilliant green of its foliage. It is a near ally of the British G. Pnewmonanthe, but a far handsomer plant. According to Dr. Royle, its native name in Garwhal is “ Kurroo,” and it is used asa medicine, no doubt from the bitter properties of the root. I am indebted to Mr. Bull for the beautiful specimen here represented, which he raised from seed, and flowered in October of last year. It had not before been introduced into cultivation, and will prove a very great acquisition to the rock-garden. Descr. Jootas thick as the middle finger, and cylindrical when old, sometimes five to six inches long, covered with black rough bark, the crown bearing many tufts of leaves that spread horizontally.

P. Thomsonianum, Reichb. f. in Gard. Chron. 1879, ii. 582. I am quite unable to refer this beautiful little plant to any other described genus of Orchids than that in which Prof. Reichenbach has placed it, and shall leave it for Mr. Bentham to settle its position as he elaborates the genera of Orchidew for the “Genera Plantarum,” a work upon which he is now engaged. Neither in habit nor in floral characters does it appear to me to accord with Pachystoma; and if the figure of the pollinia here given is correct, and I _have no reason to doubt this (having supervised the artist when making the drawing and its analyses), it must be re- ferred to the Tribe Vandew, as now accepted, and not to the Epidendree, to which the described species of Pachystoma truly belong. I think, however, it is a question how far the presence or absence of the so-called gland is of itself a safe ground on which to divide the Hpidendree from the Vandee, more especially when it is considered that this appendage to the base of the pollen masses is formed of a portion of the column (the rostellum) that varies greatly in its nature and extent in different genera, so that Mr. Darwin remarks, that “the differences in the shape and size of the removed por- JANUARY Ist, 1880, tions of the rostellum can be finely graduated together, even within the single tribe of Vandew ; and still more closely by commencing with the minute oval atom of mem- brane to which the caudicle of Orchis adheres, passing thence to Habenaria bifolia to that of H. chlorantha with its drum-like pedicel, and thence through many forms to the great disc and pedicel of Cataseta.” If the transition steps in the development of the appendages to which the pollinia attach themselves, can be thus traced from plants so different in this respect as Orchis and Catasetum, how much easier must that be from Hpidendree to Vandew ! The subject of the present plant is a very lovely one; its graceful form, and the purity and brilliancy of its white, and the vividness of its reds, render it one of the most beautiful Orchids of its type and habit, which remind one a good deal of some Celogynes. It was sent from the west coast of tropical Africa (probably Old Calabar) by Mr. W. Kalbreyer, who desired that it should commemorate the services of the late G. Thomson, a well-known resident on that pestilent coast. I am indebted to Mr. Veitch for the loan of the specimen here figured, which flowered at the Royal Exotic Nurseries in October, 1879. Descr. Pseudo-bulbs seated on a running rhizome, one inch in diameter, orbicular, depressed, covered with mem- branous scales. Leaf solitary, six to eight inches long, lanceolate, acuminate, membranous, plaited. Peduncles one or two from the base of each pseudo-bulb, ascending, slender, pubescent, with one or two spathes, two-flowered; bract sheathing, subacute.

The erect herbaceous perennial Polygona of the section Bistorta, form one of the most beautiful features of the sub- Alpine Himalayan Flora, ornamenting the wet river banks and meadows, where growing amongst the grass they con- tribute much to the herbage, or hanging in rosy clumps from the moist precipices. P. affine is one of the latter set; 1t abounds in the Himalayan valleys from Kumaon westward to Kashmir, growing at elevations of 9,000 to 14,000 feet, but has not been found in Nepal, as often stated. In the Eastern Himalaya and in the Khasia Mountains it is replaced by P. paleaceum, Wall., a plant not recorded in Meissner’s monograph of the genus in De Candolle’s Prodromus, and which is perhaps referable to his P. sphwrostachywm. An- other and a very beautiful ally of these is P. vacciniifolium, Wall. (tab. nostr. 4622), which is one of the most orna- mental rock-plants ever introduced into this country. Polygonum affine has been long cultivated at Kew, and flowers freely in the open border in September and October. JANUARY Ist, 1880. - It was introduced into England in about 1845, I believe, through the late Dr. Royle’s collectors, who were attached to the Saharumpore Gardens. Desor. Quite glabrous. Rootstock woody, tufted, pros- trate, branched, tip covered with the brown withered sti- pular sheaths, sending up several erect flowering stems and occasional prostrate leafy shoots. Leaves chiefly radical, two to four inches long, oblanceolate or elliptic-oblong, acute or obtuse, narrowed into a long or short and slender petiole; margins recurved and minutely wrinkled, almost crenulate; nerves reticulate; stipules elongate, entire or sparingly split; cauline leaves much smaller, sessile, elliptic. Flowering stems six to eight inches high, stout or slender. Flowers in solitary terminal cylindric obtuse spiciform racemes, two to three inches long, by half to two-thirds of an inch in diameter, crowded; bright rose-red, concealing the membranous obtuse sheathing stipuliform bracts; pedi- cels fascicled often in fours, filiform, curved, rigid.

Under A. nepenthoides (tab. 6446) I stated that several other Himalayan species of this genus remained to be pub- lished from figures made from specimens introduced into cultivation by Messrs. Elwes, Gammi, King, &e., and that amongst them was the A. utile. This, on account of its being the most common of those of which the tubers are collected for food by the hill tribes of Sikkim, is the most interesting species of the genus, though it falls short in stature of the A. Hookerianum, a figure of which will shortly appear in this work. A. utile is the plant specially alluded to in the following extract from the “ Himalayan Journals,” vol. il, p. 49 :—“ My tent was pitched on a broad terrace, opposite the junction of the Zemu and Thlonok, and 10,850 feet above the sea. It was sheltered by some enormous transported blocks of gneiss, fifteen feet high, and sur- rounded by a luxuriant vegetation of most beautiful rhodo- dendrons in full flower, willow, white rose, white-flowered cherry, thorn, maple, and birch. Some great tuberous- rooted Arwms were very abundant; and the ground was covered with small pits, in which were large wooden pestles: these are used in the preparation of food from the Arums, to which the miserable inhabitants of the valley have re- course in spring when their yaks are calving. - The roots FEBRUARY Ist, 1880. are bruised with the pestles, and thrown into these holes with water. Acetous fermentation commences in seven or eight days, which is a sign that the acrid poisonous principle is dissipated: the pulpy, sour, and fibrous mass is then boiled and eaten; its nutriment being the starch which exists in small quantities, and which they have not the skill to separate by grating and washing. This preparation only keeps a few days, and produces bowel complaints, and loss of the skin and hair, especially when insufficiently fermented. Besides this, the ‘ choklibi’ (Tovaria olevacea, tab. 6313), and many other esculents, abounded here; and we had great need of them before leaving this wild uninhabited region.” The drawing here published was made from a specimen sent to me by H. J. Hlwes, Esq., F.L.S., of Preston House, Cirencester, who himself introduced it from Sikkim; it flowered at the same time (June 14, 1879) in the Royal Gardens, from roots presented by Mr. Elwes. The species is common in the forests of Sikkim, at elevations of 8000 to 12,000 feet, flowering in May and June. | Descr. Tubers as large as a walnut, or larger.

This little Calochortus is a close ally of C. elegans, which is pretty well known in English gardens, but differs by its yellow flowers. For garden purposes the species of this Macrodenus section are not so effective as the larger more open-flowered Mariposas, such as venustus, luteus, citrinus, and splendens, but the flowers are less fugitive. The present Species is an inhabitant of the Sierra Nevada chain of mountains in California. It was first gathered by Hartweg in the year 1848, and has since been distributed by Fremont, Lobb, and other collectors. We first received it alive from Mr. Elwes in 1877. The drawing was made from a plant that flowered with Dr. Wallace at Colchesterin June, 1879. Descr.

P. cuspidatum, Sieb. et Zuce., var. compactum, Hort. The Japanese and N. Chinese Polygonums of the section Pleuropterus, are amongst the most ornamental herbaceous plants of the garden ; some of them, as P. cuspidatum and Sachaliense, throwing up, in the summer time, branches so numerous, long (often eight feet high), and strong, as to become truly bushes. They are of graceful habit, easily grown, perfectly hardy, and increase by underground suckers with such rapidity that the larger sorts are apt to prove troublesome monopolists of the soil. Of these Polygonums the two named above are commonly culti- vated, and both are erect; a third is a climber, the P. multiflorum, Thunb. To these must be added the subject of the present plate, which has long been cultivated at Kew under the name of P. compactum, and which, though closely allied to P. cuspidatum, and possibly a form of it, differs in its dwarf size, decumbent lowly habit, small rigid leaves with waved margins, and strict erect simple female racemes. Like all its near allies, as far as I have observed them, it is dicecious, the male plants having stamens which are longer than the perianth, and a minute rudiment of an ovary without stigmas, and the females having very short stamens EEBRUARY Ist, 1880. with imperfect anthers without pollen, and a well-formed trigonous ovary bearing three short stigmas fimbriate at the apex. Besides the form figured here, a similar one in habit and foliage is grown at Kew, with the flowers all male, rose-coloured, much more loosely racemose, and with a tendency in the racemes to throw out very short lateral branches: this plant I suspect to be the male of P. com- pactum. The only specimen of P. compactum which I have found in the Kew Herbarium were fruiting ones collected on the mountain Fusiyama, received from Sir RB. Alcock, K.C.B., in 1860, from whom, in all probability, the seeds also were procured ; like all its allies, it flowers very late in the season, the specimen figured being in blossom almost till the end of September. Duscr. Stems prostrate, one to two feet long, with ascending and suberect branches as high, deeply grooved, dark red or red-brown, puberulous towards the tips, aS are the petioles and racemes. Leaves one and a half to two inches long and broad, rigid, deltoid or very broadly ovate, base broadly truncate or subcordate with a very open sinus, cuspidate, margins waved, uppermost sometimes cuneate at the base; petiole a quarter to half an inch long, stout, red ; ochrea very short, deciduous. Racemes axillary and terminal, two to three inches long, strict, erect, solitary or several together; rachis slender with close-set short obtuse many- flowered bracts. Male flowers white, on slender pedicels ; perianth one-tenth of an inch long, subglobose ; fruiting perianth one-third of an inch long, cuneate, truncate ; three outer segments with a broad membranous longitudinal dorsal wing produced downwards on the pedicel.

Its nearest ally is the M. picta, Hook., figured at Tab. 3154 of this work, a native of the Organ Mountains (Rio de Janeiro), and which differs in the pseudo- - . bulbs, fewer bracts, and in the colouring of the much larger very sweet-scented flowers. Both belong to the largest section of the genus, many of which have a good deal the habits of Indian Coelogynes, which genus Mazillaria in some respects represents in America. Reichenbach describes the pseudo-bulbs of this species as covered with numerous wrinkles, which not being the case in the specimen here figured, is probably due to a want of ripening, or to a too advanced state of that organ, which in a healthy condition is perfectly smooth. The flowers, which are copiously pro- duced, have no scent, but owing to their bright golden colour the plant is a very attractive one. The specimen figured is from a plant about a foot in diameter, which is covered with flowers in the early months of the year. Desor. Pseudo-bulbs one inch long and hardly so broad, FEBRUARY Ist, 1880, orbicular-ovoid, compressed, with blunt margins, obscurely grooved, quite smooth and even, not contracted into a neck; spathes narrowly lanceolate, acuminate, brown, equalling the pseudo-bulb. Leaves two from each pseudo-bulb, five to seven inches long by one half an inch broad, obtuse, keeled, narrowed at the base, deep green, midrib yellowish. Scapes from the base of the pseudo-bulb, much shorter than the leaves, one-flowered, with four to six green subacute sheathing bracts, the lower of which are imbricate; the uppermost is three-quarters of an inch long, rather inflated, obtuse, almost as long as the ovary.

As a species it is unique in the genus as to the form of the corolla, the lobes of which are free only in the inflated basal part, and are above that combined into a very slender tube, with an entire or merely toothed mouth, which closely sheaths the style; in all the other species of the genus, of which there are between forty and fifty, the corolline lobes, though coherent for a considerable period before fertilization is effected, are finally free. In P. comoswm the openings at the base of the corolla are no doubt efficient promoters of cross-fertilization, for insects seeking the honey secreted by the disk capping the ovary, would ine- vitably carry away pollen with them, wherewith to dust the forest of exserted stigmas. P. comosum is a native of the Eastern Alps of Austria, Lombardy, Istria, Dalmatia, and Transylvania, where it inhabits elevations of 4000 to 5000 feet, its favourite site FEBRUARY Ist, 1880. being on dry rocks. The specimen figured is a very small one; those preserved in the Herbarium have radical leaves an inch broad on capillary petioles three to five inches long, and heads of flowers three inches in diameter, and there are often thirty to forty flowers in a head.

The plants belonging to the Order Pontederiaceew are de- scribed in systematic works ina very unsatisfactory manner; this is due to the fact that their very fugacious flowers cannot be analyzed in herbarium specimens, on account of their membranous consistence, and to the variations to which the leaves and stems of the same plant are subject, according to whether it grows in deep or shallow water or inmud. The genus Pontederia of Linnzeus was in 1843 rightly divided into two by Kunth, who retained the old name for the species with one-ovuled ovarian cells, and founded upon the many-ovuled the new genus LHichornia. Seubert, in Martius and Endlicher’s Flora of Brazil, has adopted those genera, describing six 8. American species of the former and eight of Fichornia. It is with the latter we have to do in the matter of the plant here figured, and APRIL Ist, 1880. I am unable from the descriptions to refer it altogether satisfactorily to any described species. Of these, only one of the species with racemose inflorescence has been hitherto well figured, namely, that referred (t. 2932) to Swartz’s Pontederia azurea (which is also figured in Martius’ “ Nova Genera et Species,” as P. crassipes, Martius). This Kunth considers not to be Swartz’s plant, and makes a new species of it; H. speciosa, Kth. In so doing he is very probably justified, though it is to be regretted that he did not retain Martius’ characteristic name of crassipes, especially as he quotes that author’s description and figure. Swartz’s P. azurea, then, is Kunth’s Hichornia azurea, and the doubt in my mind is whether the subject of the present plate is referable to it. On the one hand, it appears to agree with a specimen of the only Jamaica species known to me which could be considered as Swartz’s azwrea, gathered by Purdie, and which Grisebach considers the true one; on the other hand, neither Swartz, nor P. Browne in his full description, alludes to the beautifully-toothed inner perianth segment of our plant, nor can the latter author’s description of the | Stamens be regarded as quite satisfactory: “ filamenta..3 superiora ad basim tubo adnata; 3 inferiora in fundo floris sita.”” Browne adds, “I observed this plant in most of the Lagoons about the Ferry ;” and Purdie’s ticket bears “ Habitat, behind the Ferry,’ which must be regarded as settling the point in the present state of our knowledge. The figure cited of Schlechtendahl, appears to represent a larger-flowered plant than this, with flowers not in pairs, almost orbicular-obovate, much larger inner perianth lobes, and the eye-like spot rounded. Li. azwrea is, as far as can be ascertained by a comparison of dried specimens, a common tropical South American water-plant, extending from South Brazil to Jamaica; it varies greatly in the size and form of the leaves and length of the petiole, and is found either floating, or rooted and erect in the muddy bottom of shallow water. It was introduced into the gardens of the Royal Botanic Society, Regent’s Park, from Brazil, and flowered there in July of last year, and I am indebted to Mr. Sowerby for the plant here figured. Descr. Stems as thick as the thumb, floating and rooting, green, smooth, flexuous. Leaves on long or short petioles, which are not inflated, very variable in size and shape, three to eight inches in diameter, from rounded cordate to trapeziform or rhomboid or very broadly oblate and obcor- date, rounded retuse or subacute at the tip.

Brown has, in the ‘Gardeners’ Chronicle” quoted above, cleared up the confused synonymy and history of this beautiful plant. It was published first in 1806, by Andrews, as the Linnzan SV. pseudo-china, it being supposed to have been introduced from that country, and to afford the drug called ‘“ China-root,” which, however, involved a second mistake, as that drug is the produce of a Smilaz. It next appeared in Willdenow’s ‘‘ Species Plantarum,” the author of which, recognizing ‘its difference from Linneeus’ S. pseudo-china, called it S. specitosus. In 1816 Ker figured it under Willdenow’s name in the “ Botanical Register,” observing that the native country of the plant was not precisely determined, it being called Siberian by some and Chinese by others. Ten years afterwards Loddiges figured it in his “ Botanical Cabinet,” as intro- duced by him from the Mauritius, adding that it is a supposed native of China. In 1837 De Candolle, having South African specimens of Ecklon and Drege before him, APRIL Ist, 1880, and not recognizing their identity with S. speciosus, pub- lished it as a variety of his S. concolor, placing it, however, close to the supposed Chinese S. speciosus, whose true relationship to the otherwise wholly African group of this difficult genus he had the sagacity to discern. Lastly, Harvey, in the ‘Flora Capensis,’” describes it as var. Ahispidus of S. concolor, DC., and suggests that it should be regarded as the type of that species. In this he clearly errs, S. speciosus being a very different and far finer plant than S. concolor, with which, however (and with very few others of the genus, and these all, according to Mr. Brown, South African), it agrees in the disk flowers being almost concolorous with the ray. The specimen here figured was flowered in July last in the Royal Botanical Gardens of Edinburgh, from seeds collected in December, 1878, on the battle-field of Quintana, by Sergeant D. Williamson. It has a wide range in South Africa, from the Cape of Good Hope itself to Natal, and, as Mr. Brown remarks, its supposed Chinese origin is pro- bably due to its having been brought by one of the home- ward-bound China-ships, which regularly touched at the — Cape. According to the “Hortus Kewensis,” it was introduced into England about 1789 by G. Slater, Esq. Duscr. Root stout, fleshy, perennial.

This ig one of the many interesting bulbous plants which have been discovered during the last few years by the Russian explorers in Central Asia, and which have been sent alive to St. Petersburg by the exertions of Dr. Albert Regel, and liberally distributed by his father amongst the Kuropean public gardens and amateurs. The present plant is a close ally of the well-known Xiphion reticulatum of the Orient and the Caucasus, of which a good figure under the name of Iris reticulata will be found Bot. Mag. Tab. 5577. The principal difference between the two is not in the flower, but in the bulb and leaves. It flowers at the same time, and has something of the same violet odour, and in all likelihood will prove equally hardy. It grows plentifully in fields near Wernoje, in Turkestan, and was named by Dr. Regel in compliment to General Von Kol- pakowsky.

When it flowered for the first time, a bloom was sent to Prof. Reichenbach, who named the plant in compliment to the gentleman through whose instrumenta- lity it was introduced into British gardens, and for whom Messrs. James Veitch and Sons purchased the stock.” I am indebted to Messrs. Veitch for the specimen here figured, which flowered in October, 1879, in their establish- ment at Chelsea. : - Descr. Stemless.

It was discovered by Griffith in Bhotan, at eleva- tions of 3000 to 5000 feet, and named, from imperfect spe- cimens, after its discoverer by Schott, who however failed to recognize it amongst the species subsequently brought by myself from Sikkim, and transmitted to him for exami- nation, and he consequently gave to the latter the name of A. Hookerianwm. A comparison of Griffith’s Bhotan speci- men with my own does not enable me to detect any difference between them, though the latter appears to affect — a much higher elevation, for I have never gathered it much below 8000 feet of elevation, and it ascends to 10,000 feet. Under A. utile (Tab. 6474) I have described the use to which the tuberous roots of this and other species of MAY Ist, 1880.

The “swamp Gooseberry” of the United States of America inhabits cold wet situations, especially the banks of mountain rivers across the whole continent, from the Arctic Circle in Canada to Sitka and British Columbia, and from New England to Northern California, retaining its habits and characters in more northern situations and throughout the Eastern States, but becoming less bristly and more spiny in California, where, too, the leaves are pubescent. Though unattractive in point of inflorescence, its beautiful green delicate foliage and the purplish-brown branches render it a desirable shrub for cultivation. The _ fruit, which is always small, seems to vary in quality. Asa Gray describes it as “unpleasant” in New England; Lindley (under R. echinatum) says, on Douglas’s authority, “berries black, pleasant ;”” Sereno Watson describes the fruit of the Californian variety as “acid, intermediate be- tween a gooseberry and a currant;” the colour of the berry, too, is variously described as dark-brown, red, amber, and -purplish-black. : Though introduced so long ago as 1812, according to May Ist, 1880. .

In fact, I have no doubt that P. elegans is nothing but the lovely P. rosea, figured last year (Tab. 6437); the only difference I find in the description is, that the flowers of P. elegans are, on its discoverer Jacque- mont’s authority, lilac, which may be accounted for by the flowers having faded; in fact, Duby says of his elegans, “an a priore (rosea) revera distincta?” The close affinity of the plant here figured to the P. sibirica is evident from referring to the plate of that plant (Tab. 3167), which represents its large flowered state, and it is still more like the P. sibirica var. integerrima (Tab. 3445), a native of the Altai mountains, which only differs in the corolla-tube being elongated and twice as long as the calyx. In a dried state it is very difficult to distinguish P. sibirica from P. involu- crata (P. Munroi, Lindl. Bot. Reg. 1847, t. 15), which, however, differs in the shorter calyx, long corolla-tube, pale May Ist, 1880. almost white flowers, with a deep narrow sinus between the divisions of the corolline lobes. The Siberian Primrose has a very wide range of geographical distribution, from Lapland and Sweden across the continents of Europe and Asia to Dahuria, and it reappears in Arctic America; its southern limit, however, is Kashmir, from whence seeds were sent to the Royal Gardens by Dr. Aitchison, which flowered in June of last year.

Of the genus Mormodes seven species are now figured in this work; M. pardina (Tab. 3879 and 3900), M. Cartoni (Tab. 4214), M. lentiginosa (Tab. 4455), M. atro- purpurea (Tab. 4577), M. Greenii (Tab. 5802), M. Colossus (Tab. 5840), and the subject of the present plate, all of them differing remarkably from M. Ocane, both in the form of the perianth-segments and their colouring, but agreeing in the singular arrangement of the column, which is twisted one quarter round so as to bring the anther to face side- ways, and to afford a landing-place to insects close to or upon the anther itself. In M. Ocanw the slender beak of the column, to which the anther case is hinged, rests on the side of the mid-lobe of the lip, and when touched the whole anther with its broad strap and gland is released from the column with a jerk, and is, according to Dr. Reichenbach, frequently tossed into the concavity of the lip itself ; for that learned author remarks (Gard. Chron. l. c. 582) that the three lobes of the lip form as many bags, in one of which he always found a pollen-apparatus ; and he IUNE Ist, 1880. adds that these bags may be regarded as show-rooms for insects which can carry away those bodies (the pollen) strongly glued to them by their viscid glands. For a complete account of the structure and formation of the lip and pollen apparatus of Mormodes I must refer to Mr. Darwin’s work on “ The Fertilization of Orchids” (p. 208), where it is shown how perfectly all the parts are contrived and arranged to cause the pollen to alight on an insect visiting the flower, and to be thence carried to other flowers in a position to secure their fertilization. M. Ocane was discovered by the collector Schlim in the province of Ocafia, at elevations of 4000 to 5000 feet, and subsequently collected by M. Kalbreyer. The specimen here figured was cultivated by Messrs. Veitch, with whom it | flowered magnificently in October, 1879. Descr.

On first seeing this beautiful plant, I did not suspect its kinship with Gentiana septemfida, of which two forms, equally dissimilar from one another and from this, and both very inferior to it, are figured at Tabs. 1229 and 1410; and I was further deceived by the name of G. gelida being attached to it. On comparison with the published descrip- tions of the gentians, I find that this is undoubtedly G. cor- difolia of ©. Koch, which is rightly reduced by Boissier to a variety of septemfida, from which latter, in all its forms, G. gelida differs only in its ochroleucous flowers and the entire or two-fid plaits between the lobes of the corolla, and may be a mere variety of this. Both these species are described as having the leaves scabrid on the margin, a character which I do not observe in either the living or Herbarium specimens. The corolla-lobes in the typica forms vary from five to seven, whence the specific name. Gentiana septemfida has a wide range in distribution from JUNE Ist, 1880. Tauria and the Caucasus to Persia and the Altai mountains, ascending to 9000 feet in the Caucasus, and the var. cordi- folia inhabits the mountains of Armenia. Iam, unfortu- nately, unable to say whence the specimen here figured was procured, the drawing, with notes attached, having been lost in London after having been made use of by the ~ - colourist; it is, however, a well-known cultivated plant under the name of G. gelida, but it does not at Kew arrive at the stature of the specimen figured. : Desor.

To pronounce a species of Muwellia as “hitherto un- described”? is no light matter, for the genus contains upwards of one hundred and fifty known species, which are described under various generic names and in many scattered works, often very imperfectly. Moreover, these have been referred, as often wrongly as rightly, to no less than fourteen genera, none of which should have been separated from Ruellia, and some of them to other genera, which have nothing to do with Ruellia. I fail to match it with the descriptions of any of the species of Ruellia (or Dipteracanthus, now united with Ruellia) in Martius’s Flora Brasiliensis, where, if known in European Herbaria, this pretty plant would no doubt have been described. I have hence been compelled to give it a name, and have chosen for the purpose that of the donor, Sefior Francisco Portella of Campos (Rio de Janeiro), who sent it in a ward’s-case with various other valuable living plants of Brazil. It appears to be a very free-growing species, well adapted for winter decoration as a stove plant; and, like others of its order, requiring to be kept quiet when flowering and fruiting are over.

Grefferi is a South European plant, with a very ex- tended geographical distribution, from the Azores and Canaries to Portugal and Morocco, and thence eastward to Asia Minor and Northern Syria. It does not occur anywhere north of the Alps except in Western France, but has been introduced into South America and other countries. It affects wet places, and when grown in a pot standing in a tank or pan of water, it forms a strikingly ornamental plant from the profusion of its bright pink blossoms, which stud the numerous slender branches, and which appear in suc- cession for several weeks. The figure published as L. Greef- ferii in Loddige’s Botanical Cabinet is unrecognizable, and from the small flowers and opposite leaves probably repre- sents L. hypopifolium, L. The figure of L. flecuosum, Lag., in Regel’s Gartenflora, again, has most of the leaves opposite, and the petals very narrow, not like those of L. Greefferi. JUNE Ist, 1880, I have retained the well-known and hitherto universally adopted name for this plant, though it can hardly be doubted that one of the earlier ones of Lagasca (fleewosum and acutangulum), published in 1814, is of earlier date. The descriptions, however, of Lagasca are very unsatisfac- tory, and he made two species out of the one. The Royal Gardens are indebted to Mr. Joad, F.L.S., of Wimbledon, for plants which flowered profusely during the month of August. Descr.

The Himalaya Mountains are as remarkable in a botanical ‘point of view for the beauty of the colouring of the flowers of their Polygonums, as Japan is for the stature and noble foliage of some of the species of the same genus which it contains. Amongst the Himalayan kinds none exceeds P. amplexicaule, which is unrivalled for graceful habit, foliage, and colouring combined, and it is further a plant of such easy cultivation, that it ought to be a garden favourite. It occurs under two varieties, a white- and a red-flowered, of which the white has usually a longer and more slender raceme, with more distant flowers. These two varieties do not correspond to any two of the five species which have been founded on dried specimens of the plant, and JUNE lst, 1880. which I agree with Dr. Lindley in considering to be un- worthy of varietal rank. P. amplewicaule extends through the whole range of the Himalaya, from Murree in the extreme north-west, where it ranges from 6000 to 8000 feet of elevation, to Sikkim, where it reaches 11,000 feet and upwards; it does not occur in the Bhotan collections of Griffith, nor has it been found in the Kharia range. It was introduced into the Horticultural Society’s gardens from those of Tahurunpore, by Dr. Falconer, in 1835 or 1836; but our figures are made from plants raised at Kew from seeds sent by Dr. | Aitchieson, and it flowers in September and October.

This very remarkable and handsome variety of the well- known Cross-vine of the Southern United States has been long cultivated in the conservatory at Kew, and differs so ' widely from the typical form of the species, that but for numerous intermediates, of which we possess Herbarium ‘Specimens, it might be assumed to be a different species. The leaflets are both longer and narrower than is usual, but as these vary from those figured here to broadly oblong, no importance can be attached to the form of these organs. In the corolla the divergence from the type is more marked ; in most of both wild and cultivated forms this organ is usually shorter, with five broad rounded and often notched widely-spreading lobes, so that the limb is an inch and a half in diameter, the colour being orange-yellow with red- purple on the tube; here, on the other hand, the corolla is wholly of a dark red-purple, with the tube nearly two inches long, and the lobes short, triangular-ovate, acute, and not one-third of an inch in breadth and length. Now that attention has been called to the variation of this plant, no doubt other as great deviations from the type will be introduced into cultivation. Of these I have seen dried specimens of one, sent from Kentucky, which JULY Ist, 1880. has the corolla-tube one and a half inch long by fully two- thirds of an inch broad, and swollen like a campanula ; another form has the corolla curved nearly into a quadrant. Bignonia capreolata is one of the loftiest climbers in the © forests of the Southern United States, from Virginia to Florida and westwards to the Mississippi, where it orna- ments the rocks and trees by its luxuriant foliage and (usually) orange-yellow flowers. The American name of Cross-vine is given in reference to the wood of the stem, which ona transverse section presents the form of a cross.— vO.

There is still a third species of this group to figure, the P. sachaliense, the largest of all, and of which a drawing is prepared for this work. P. cuspidatum is a native of Japan, and there is in the Herbarium a very similar plant from North China, collected by Dr. G. Shearer at Kieu Kiang; the specimens of this JULY 1st, 1880. are, however, not sufficiently good to pronounce upon, and the racemes from which the flowers have fallen are much shorter and more fascicled. — This species was introduced into England many years ago; it has been cultivated for a quarter of a century at Kew, to which it was, I believe, sent from Holland. Like the rest of the half-shrubby species, it flowers very late in the season, and is diceceous. : Desor.

It is somewhat singular that so long-known and beautiful a herbaceous plant as the subject of the present plate should be seldom seen in cultivation. The only figure of it given | in an English work is that of a smaller flowered more hairy variety by Lindley in the “ Botanical Register,” who says of it: “In its native stations it is one of the most lovely objects imaginable. Often have we heard travellers from Italy expatiating upon the beauty of the spots which are enamelled with the bright blue flowers of this interesting stranger, but it was never our good fortune to see it alive, till we met with it in the garden of Mrs. Marryatt at Wimbledon.” : The specimen here figured is of a large-flowered form, which I found in the garden of Miss Wedgwood, at Down, JULY Ist, 1880. in Kent. According to Alphonse De Candolle, it is a native of the evergreen region of Italy south of latitude 41°, and struggles through the lower woodland region up to the upper limits of the beech, about 3000 feet above the sea, growing in exceedingly dense tufts on limestone rocks. We have, however, specimens gathered by Mr. Grove at 5000 feet elevation, in the valley of Orfenda of the Abruzzi. Descr.

Bot. vol. x. t. 171. - The nomenclature of the species of Berberis presents many difficulties, and though I am satisfied as to the present plant being the B. buwifolia of Lamarck, figured in his “Illustrations” in 1802, and B. dulcis of Sweet, published in 1838, I am not persuaded that it may not have an earlier name than either of these. The difficulties referred to arise from the extreme variability both of the foliage and the inflorescence. Of these the latter is used for sectional characters, according as the flowers are soli- tary, fascicled, or corymbose; but when the corymb is sessile, the flowers appear fascicled, and it is often the case that the flowers of the fascicles are reduced to one. Thus I in the “Flora Antarctica,” and De Candolle in his Systema (vol. ii. p. 15), have referred to this species Forster’s B. microphylla, a Fuegian plant, found by me as far south as Cape Horn itself, which has short three- flowered peduncles, which are often reduced to one-flowered ones, when it closely resembles B. buzifolia, but it differs in a character which is almost unique amongst the high JULY Ist, 1880, southern species of the genus, of the leaves, which are very small, being deciduous, and the flowers appearing with the very early leafy shoots. More similar still to the present plant is Ruiz and Pavon’s B. virgata (Fl. Peru and Chili, vol. 1. p. 51, tab. 281, f. B.), a native of the mountains of Peru; but here again the flowers (though described as solitary by De Candolle) are stated by its authors to be three, or sometimes two or four, and the peduncles are short, compared with those of B. buwifolia. Berberis buxifolia ranges from Chili to the Straits of Magellan, and probably further south, but in Fuegia it is replaced by B. ilicifolia and B. microphylla. Tt was intro- duced into cultivation by seeds collected by Mr. Anderson, the botanical collector attached to Captain King’s survey of the Magellan Straits, which were raised in Mr. Low’s nursery at Clapton. It has long been cultivated at Kew. The berries are eatable. oe Descr. An erect glabrous rigid shrub.

This, the indigenous Indigo of the West Indies, is the representative of the I. tinctoria or Indigo of the Old World ; but both of these plants having been cultivated for some centuries for the extraction of the well-known dye, are now naturalized in the tropics of the Old and the New World. Of the two species, I. tinctoria was known for its product from very early times, being in use by the Egyptians and described by Dioscorides; whereas the I. Anil could not have been known in Europe or the Hast until after the discovery of America. An Indigo appears, however, to have been used by the natives of the New World before it was brought into competition with the plant of the Old; for Sloane (Hist. Jam. vol. ii. p. 37) says, ‘ Robt. Tomson ap. Hakl. p- 454, found it about Mexico, where it is used to die blue.” It is, however, very doubtful if the plant here alluded to be the Indigofera Anil. It is a somewhat singular fact that although the Indigofera tinctoria has been for so many centu- ries the only Indigo-plant known in the Old World, the first species recognized by botanists was the West Indian LI.

Smith (in Rees’ Encyclopedia), Gerarde in 1597, and Johnson in 1632, knew nothing of any Indigo- plant, Parkinson in 1640 being the first to treat of it as “Indico or Indian Woad,” giving a figure of the leaf from De Leet, and describing it, first from Ximenes in Leet’s description of America, and secondly from Mr. William Finch, in Purchas’ Pilgrims. Ray, in 1688, says that it is not agreed from what plant Indigo is made, and suggests that it is from a leguminous one allied to Colutea; he describes it from Hernandez and Mareraaf, and subjoins the description of the (Indian) “ Ameri” from Rheede’s Hortus Malabarius. Here for the first time the American and Indian species are botanically both alluded to, though as one, nor were they distinguished till a much later period. Linnzeus, in the 1753 edition of the Species Plantarum, describes only the Indian species, nor was it till the publication of his Man- tissa, in 1771, that the American was recognized as different, by its much smaller flowers and more curved pods, which are even (not beaded). For further informa- tion on the much-vexed question of the J. Anil, I must refer to A. De Candolle’s “ Geographie Botanique,” vol. ii. _ p. 855. Our figure of [. Anil is taken from a plant that flowered in the Economic House at Kew. ‘The artist, Mrs. Barnard, observes that the petals of the keel separate elastically when touched. Descr.

From the elevations at which it grows in the Himalaya, there is no prospect of Bucklandia being hardy in England, but as a greenhouse ornament no plant of the class can be more attractive. The trunk is cylindric and straight in well-grown trees, and, together with the oblong crown of evergreen foliage, attains 100 feet in height.

Nothing can exceed the beauty of the young foliage of Bucklandia, and this has induced : me to figure it for the Borantcan Macazine without fresh flowers, which will probably not be produced for several years. The foliage figured is that of young trees, three to five feet high, at present standing on the shelves of the Temperate House at Kew, and which are about as many years old; they were raised from seeds sent by Dr. King, of the Calcutta Botanic Garden, and Mr. Gammie, of Dar- jecling. The figure represents by no means the largest leaves on the plants, some of which are nearly a foot in diameter. The leaves of the young plant have often three to five cusps irregularly placed beyond the middle. Those of the full-grown tree are much smaller and are always entire and green. Desor. A tall erect evergreen tree.

STENOMESSON LUTEOVIRIDE. Native of Ecuador. Nat. Ord. AMaRYLLIDACEA.—Tribe PancRaTIEZ. Genus Stenomesson, Herb.; (Baker in Ref. Bot. sub t. 308.) Srenomesson (Coburgia) Juteo-viride; bulbo globoso tunicis membranaceis brunneis collo elongato cylindrico semipedali, foliis synanthiis lineari-loratis viridibus, scapo ancipiti terminali sesquipedali, umbellis 5—6-floris pedicellis brevibus, spathe valvis magnis ovato-lanceolatis, perianthio luteo-viridi 4- pollicari, ovario oblongo, tubo subcylindrico, segmentis oblongis cuspidatis tubo 2-3-plo brevicribus, filamentis dimidio inferiori in coronam coalitis margine inter filamentorum partem liberam dentibus deltoideis integris vel obscure dentatis preedito, antheris fulvis lineari-oblongis, stylo exserto. This is a new species from the high Andes of Ecuador, which flowered for the first time in the spring of 1879 with Messrs. E. G. Henderson and Son, of the Pine Apple Nurseries, Maida Vale. It is nearly allied to the well-known Coburgia trichroma of Herbert (Bot. Mag. tab. 3867), and quite similar to it in its cultural and climatic requirements. The present plant differs from trichroma in the colour of its flowers and by its longer corona and more acute green leaves. There does not appear to be any valid character to separate Coburgia as a genus from Stenomesson, and the latter has the claim of priority. I do not think we can properly regard the first six species of Coburgia as admitted in Kunth’s Synopsis as more than mere varieties of the plant that was first described by Ruiz and Pavon in 1802 under the name of Pancratium variegatum. Descr. Bulb globose, two or three inches in diameter, with thin brown membranous tunics, which extend up the cylindrical neck to a length of six or eight inches. Leaves about four, contemporary with the flowers in spring, linear- lorate, fleshy, bright green, glabrous, a foot long at the flowering-time, an inch broad, narrowed gradually to the AUGUST Ist, 1880. point. Scape green, ancipitous, produced from the end of the neck of the bulb, a foot and a half long. Umbel five- or six-flowered ; pedicels very short; spathe-valves ovate- lanceolate, green at the flowering-time, two or three inches ‘long. Ovary oblong-trigonous, green, half an inch long; perianth-tube subcylindrical, greenish-yellow, between two and three inches long; segments oblong, cuspidate, perma- nently ascending and much imbricated, yellow with a distinct green keel, an inch long. Corona green, half an inch long, inserted at the throat of the perianth-tube, furnished with a simple or obscurely toothed deltoid process between the base of the free portion of each filament; anthers fulvous, linear-oblong, versatile, under half an inch long. Style finally much longer than the perianth ; stigma capitate.—J. G. Baker.

This is the African representative of the Persian and Caucasian Hpimedium pinnatum, tab. 4456, from which it is distinguished by its leaves being invariably only tri-folio- late, and by its much more strongly ciliate-toothed leaflets, which are perennial, and when young of a beautiful bronze- colour shot with green. In the form and colouring of the sepals and petals these two species are so alike that they can hardly be ranked higher than geographical forms, and it is far from improbable that specimens connecting them will be found in Southern Europe, if not in Africa. The texture of the leaves is so firm that even in this climate they persist during the winter. ce Epimedium Perralderianum is a native of the moun- tain-woods of Babor, Foughell and Tababor in Hastern Khabylie, at elevations of 3000 to 5000 feet, whence it was introduced into cultivation by Dr. Cosson. The plants from which our figure is taken are perfectly hardy in Kew, and were presented by Dr. Reichenbach. AvGustT Ist, 1880. The species is named by Dr. Cosson after H. de Perraudiére, one of his companions during an expedition into the mountains of Eastern Khabylie in 1861, when the species was discovered. It flowers early in June. Dusor. Sparsely clothed with spreading lax scattered hairs. Leaves 3-foliolate, petiole slender, rigid, flexuous, a span long and under; leaflets rigid, coriaceous, two to three inches long by one and a half to two broad, ovate-cordate or orbicular-ovate, acute, acutely closely ciliate-toothed, basal sinus deep narrow, the rounded basal lobes sometimes over- lapping, rigid, when young of a fine red bronze colour shot with green; petiolules one to one and a half inch long. Scape equalling the leaves, springing directly from the root-stock, many-flowered; raceme glandular-pubescent, twelve- to twenty-flowered ; pedicels slender, one-third to two-thirds of an inch long, horizontal; bracts small, caducous. Flowers bright yellow, three-quarters to two-thirds of an inch in diameter. Ezternal sepals minute, oblong, caducous ; inner orbicular or broadly oblong, horizontally spreading, broadly _Imbricate.

It is referred by Mr. Baker in his valuable paper on the aberrant tribes of Liliarew to the group Heluniee, and its immediate affinity is with the Kastern N. American genera Helonias and Chamelirium.

It was introduced from Mexico by Verschaffelt in 1862, and is now to be found in all the more complete collections, but usually under the name either of Regeliana or Desmetiana, both of which rightfully belong to species of another section. I am not aware that there is any record of its having flowered. Our drawing was made from a plant in the collection so liberally lent to Kew by J. T. Peacock, Hisq., of Hammer- smith, which has been on exhibition for a considerable time in the south wing of the Temperate House, where it flowered in the spring of this present year. he flowers are notably proterandrous, the style not reaching its full length, nor the stigma becoming papilldse, till long after the anthers of the same flower are withered. I believe that A. triangularis, grandidentata, and Maigretiana of Jacobi, and A. Gilbeyi of Haage and Schmidt, will all prove to be forms of this species. AauGusT lst, 1880. Duscr. Acaulescent.

This is a very fine new Crinum of the ornatwm group, of which the bulb was sent home about two years ago by Dr. Kirk from Zanzibar. It flowered for the first time at Kew in the autumn of 1879. Its nearest ally is C. Forbes- tanum, from Delagoa Bay, which was lost for a long time, but which we have again lately received and flowered. The present plant has flowers as large and as brightly coloured as in the finest forms of ornatum, but may be recognized at a glance by its short very stout peduncle and very large acuminate leaves, with a distinctly ciliated edge.

This singular and free-flowering shrub is much less known than it deserves to be, it being, in fact, almost un- known in English gardens, though perfectly hardy, free- flowering, and sweet-scented. It has stood unprotected in the open border of the Arboretum of Kew for several years, and hitherto has been quite uninjured, even the tender young shoots resisting the early frosts and long-protracted cold of the last two inclement seasons; a fact the more singular when it is considered that the whole plant is ever- green in respect of leaves, branches, and spines, though the leaves are deciduous. : Q. trifoliata is a native of Japan, where it is much culti- vated both as a garden plant and for fences; its fruit, which resembles a small orange, is described as very bitter, and having laxative properties. As an early-flowering and sweet-scented hardy shrub, this Citrus 1s likely to prove a favourite, and should it be eventually unable to withstand a winter of unusual severity in the open border, it may still be safe on a wall with or without protection. The flowers SEPTEMBER Ist, 1880. appeared in the middle of May of this very backward year, but no fruit has been formed; the leaves were not fully developed till the end of June. It need hardly be stated that the five-petalled variety is much more attractive than the four-petalled. Desor.

A very remarkable and scarce little alpine plant, found hitherto nowhere but in the mountains of Corsica, at ele- vations reaching to 6000 feet. It was long supposed to - be also a native of Syria, it being described and figured by the Syrian traveller Labillardiere (under the name of Xeranthemum frigidum) as being found by him on Mount Lebanon as well as in Corsica, and we have in the Kew Herbarium a specimen of it from Labillardiere’s own herbarium, communicated by the late Mr. Webb, who obtamed the herbarium by purchase, and left it by will to Florence, but it is not stated whether it is from. Corsica or Lebanon; as however it is identical with specimens from the first-named country, it may be assumed to be a copatriot. Boissier, in his Flora Orientalis (vol. iii. p. 239), states under H. Billardieri (a Lebanon species and very different from H. frigidwm) that H. frigidum is erroneously ascribed to the Lebanon, and this is the general and, no doubt, correct opinion.

A very little-known genus, of which only two species have been discovered, the present and L. bicolor, on which the genus was founded by Lindley (Bot. Reg. 1844, t. 50), and which is a native of Guatemala. The present is by very much the handsomer species of the two, and is re- markable for the delicate colouring of the perianth, which in L. bicolor is of a greenish-yellow hue, and not speckled in the lip. The two species differ widely, this having a much longer claw, a horn, concave in front, between the lateral lobes, and a stipitate mid-lobe; whilst that of L. bicolor has a very short claw, a beard between the lateral lobes, and an almost sessile mid-lobe. : Lindley, who named the genus, called it by one of the names of Helen (Lacena), because of its beauty; a com- pliment which the Botanical Register’s representative of L. bicolor does not at all merit; he adds, however, that it may also be derived from hakis, a cleft, in allusion to the divisions of the lip. : L. spectabilis flowered at Kew in the spring of this year; SEPTEMBER Ist, 1880. the Royal Gardens are indebted to Dr. Wendland, of the Royal Gardens of Herrnhausen, Hanover, for the plant.

He describes it as growing profusely in grassy marshes, at elevations of from 8,500 to 11,000 feet, and flowering in July and August. It was first found by Royle’s collectors, sent from the Saharunpore Gardens to Kashmir, and flowered at the Royal Horticultural Society’s Gardens in 1840, whence the figure in the Botanical Register was made; but neither this figure, nor Royle’s, gives any idea of the intense sapphire-blue of the corolla. It has also been collected in Kashmir by Jacquemont and Falconer, and, as one of the most beautiful plants of that botanically rich valley, it can hardly escape the notice of future collectors. Dr. Lindley describes it as “one of the gayest of our perennials, in consequence of the striking contrast between the white and blue of its large flowers.” The specimen here figured flowered in the herbaceous grounds at Kew in June of the present year.

The two plants represented in this plate are amongst the least showy species of the genus. 1’. biflora has been long known, but is very seldom seen in cultivation. It is spread from the Volga through the western half of Siberia. It is notable in the genus for producing normally more than a single flower. It has a woolly bulb, like montana, but otherwise its affinity is with sylvestris and australis. The drawing was made from a plant sent up by Mr. George Maw from his garden at Broseley. : T’. iliensis is one of the numerous new species that have lately been discovered by the Russian explorers in Central Asia. Its alliance is close with 7. triphylla, Bot. Mag. OCTOBER Ist, 1880. tab. 6549. In their flowers and leaves these two resemble australis, but the stamens are like those of Gesneriane.

Meyer, Verz. Pf. Caue. p. 165. This has been for many years one of the most conspicuous spring ornaments of the Royal Gardens, where it forms a dwarf tree, standing to the west of the Cactus House, near the fine specimen of Pinus Coulteri, and so covered with white flowers in March or April (according to the season) as to appear as if snowed over. The flowers appear with _ the half-developed leaves, but have never been succeeded by fruit. Whether this should be considered as anything more than the wild form of the Myrobalan Plum, P. cerasi- fera, Ehr. (see tab. 5934), has been doubted by the excellent observer C. Koch, as I have stated under the latter plant ; and, indeed, the characters whereby most of the native plums are separated, are not of very much moment. With regard to P. divaricata, however, its leaves, when full grown, broadening at the base, and appearing with its smaller flowers, and its fruit not being intruded at the base, together with its remarkable habit, would appear to constitute sufficiently marked diagnostic characters. The petals which are almost orbicular in the Kew specimens are more obovate in native ones from the Caucasus, collected OCTOBER Ist, 1880. by Hohenacker, and in others from the Copenhagen Gardens. Prunus divaricata was introduced into England in 1822, according to Loudon, probably from the Dorpat Gardens, when under the direction of its describer Ledebour, and is a small tree ten to twelve feet high and broad, forming a hemispherical mass on the ground with a singularly grace- ful ramification; according to Boissier, it has a very wide geographical range, from Macedonia to the Caucasus and Northern Persia. The specimen at Kew was procured by the late Curator, Mr. J. Smith, from Messrs. Osborne, of Fulham, about thirty-eight years ago. ‘Desor. A small tree, ten to twelve feet high, branching from the very base, the branches numerous, slender, wide- spreading, the lower lying almost flat on the ground; the whole forming a hemispherical or rounded mass ; branchlets slender, glabrous.

A. Greenii, Baker in Journ. Linn. Soc. ined. This is a well-marked new species of Aloe of the group Picte, which we have for some time cultivated at Kew. ‘All that I can make out for certain about its history is that it was received under the name which I have adopted from Mr. Wilson Saunders, and that this name was given to it by Mr. T. Cooper, but that it is not one of the plants which the latter collected in his travels in Cape Colony, which yielded so many interesting discoveries in this set of plants. In the Picte group of Aloes the present plant may be readily distinguished by its elongated racemes and by the strong construction of the perianth-tube at the middle.

This very beautiful plant has been long cultivated in England, though when and how introduced is not certain. It is not described in Aiton’s Hortus Kewensis, nor, up to this time, cultivated at Kew; it is not included in Mamaout and Decaisne’s ‘‘Flore Elementaire des Jardins et des Champs,” which is the fullest work of the kind known to me, nor do I find it in the more accessible works devoted to English out-of-door gardening ; yet I observed it last summer growing in the gardener’s cottage at Lytchett, and it probably occurs elsewhere, though overlooked as too like an Everlasting Pea to be worth notice. Nevertheless it is one of the most charming plants of its kind, perfectly hardy, a free flowerer, and for the brilliancy and delicacy of its rose-coloured flowers, it ought to be a favourite. Like its near ally, the Everlasting Pea, it is scentless.

I am indebted to Mr. Corderoy, of Blewbury, near Didcot, a valued corre- spondent and cultivator of succulent plants, for the specimen here figured, which flowered in his garden in June of the present year.

The genus Dracontium, as restricted by Engler in his recent monograph of the Aroidee, includes the wonderful Godwinia Gigas (tab. nostr. 6048), of Nicaragua, and consists of this and two other species, natives of N. Brazil and Guiana ; to these must be added the subject of the present plate, which extends the geographical range of the genus to the United States of Columbia, and which differs from its con- geners in the smooth petiole and very long peduncle. A sup- posed fifth species has been fully and carefully described and figured by Dr. Masters in the Gardeners’ Chronicle for 1870 (p. 344, tab. 58) as D. elatum, which differs from Engler’s generic character in the ovules being attached to the middle of the septum of the ovary, a character by which Schott separated Ophione from Wracontiwm, very unna- : _turally as it appears tome. This D. elatwm is taken up in the index of Engler’s monograph, where the name is printed in italic type, indicating its being a synonym; but the reference to a page is omitted, and I have failed to to trace it anywhere in the body of the work. Mr. Baker, NOVEMBER Ist, 1880. in a note in Saunders’ Refugium (vol. iv. tab. 282), suggests that it is only D. asperwm, and that the locality of Sierra Leone is an error. I am indebted to Mr. Bull, F.L.S., for the means of figuring this interesting plant, and take the present opportunity of recording my sense of the signal service which this ardent. horticulturist has rendered to botanical science, by the introduction and cultivation of so many fine plants of this family; plants which cannot be satisfactorily investigated except in a living state, and which, from their brief duration, lurid colours, and often foetid odour, offer no attraction to the lovers of other than rare and curious plants. D. Carderi was discovered by the traveller whose name it bears, and was imported by Mr. Bull, who flowered it at his establishment in Chelsea in April, 1879. Desor. Petiole two to three feet high, slender, terete, mottled with bands of dirty green; lamina two feet in diameter, three-sect to the base; divisions horizontal and drooping at the ends, undivided or forked at or below the middle, pinnatisect below the middle, pinnatifid beyond it; pinnules or lobes very unequal, the lower contracted or not at the base, oblong or obovate, acute or acuminate, some two to three inches long and undivided, others six to eight inches and lobed or split, or perforated, all pale green, membranous, with many arching nerves.

This singular and beautiful plant has attracted much attention, on account both of its horticultural and botanical interest ; differing as it does from all other species in the remarkable character of its petals, and yet presenting so many points of resemblance to a world-wide garden favourite whose native country is unknown (the H. fiosa Sinensis), as to have suggested its specific identity with that plant. The differences, however, between this and H. Rosa Sinensis are a great deal too many and too impor- tant to render the idea of this being a sport or variety of that plant tenable. They are, firstly, the petals, which, however, might have originated as a sport; then the pendulous flower, the suppression of the epicalyx, the longer tubular calyx with obtuse lobes; above all, the long fruit with small smooth seeds. I have examined specimens of H. Rosa Sinensis from thirty different localities, and found none approaching BR. schizopetalus in any of the above characters. Too much importance should not be attributed to the supposition that the native country of NOVEMBER Ist, 1880. 23: H. Rosa Sinensis is not well known; Loureireiro states that it is indigenous in both China and Cochinchina, and it has certainly been for long cultivated in China, and it occurs in so many of the Pacific Islands as to render it very probable that it is a native of the Pacific ; on the other hand, its two nearest allies, the present plant and H. liliiflorus, being natives, the one of Hast Africa, and the other of the Mascarene Islands, suggests the probability of Africa being the parent country of H. Rosa Sinensis. For the discovery of this fine plant we are indebted to our indefatigable correspondent, Dr. Kirk, H.B.M. Consul at Zanzibar, who found it first in 1874 on the coast hills at Mombasa, in lat. 4° 8.; in 1877 at Kilwa, in 7° 40’S.; and, lastly, at Lindi, in 10°S. It grows both in dry rocky slopes and in damp mountain glens, in dense shade, amongst Bignonias, Balsams, and Ferns.

Calochortus and Cyelo- bothra slide into one another so gradually that it is not worth keeping them up as distinct genera. _ The present plant was one of those introduced by Douglas about 1830, when travelling for the Royal Horti- cultural Society, and was originally described and figured by Mr. Bentham half a century ago.

The present is one of the most beautiful of the genus; it was cultivated in England before 1710, and in Holland much earlier, for it is described in Johan Commelyn’s “ Hortus Medicus Amstelo- damensis,” published in 1697, as “ Anemolospermos Africana, foliis Cardui Benedicti, florum radiis intus sul- phureis.” | According to De Candolle 4A. aspera 18 a very variable DECEMBER 18F, 1880. : plant, of which he enumerates five varieties, the last being the subject of the present plate, distinguished by the white under-surface of the leaf, and colours of the ligules.

It is not without great consideration that I have been com- pelled to give a new name to the little-known Disa macrantha of the gardens, nor would I have done so were I not well assured that the true D. macrantha is a very different plant, coming indeed from a very different part of the South African continent from that inhabited by the present species. It is true that of D. macrantha very little is cer- tainly known; it is a species of Thunberg’s, described in his “Flora Capensis ” (p. 33) as having the spur conical, shorter than the hood, the petals small, hidden under the hood, rounded at the base, faleately recurved in the middle, angled posteriorly, dilated retuse and crenulate at the end, the lip oblong acute keeled suberect, and the anther &e. as in J. cornuta, than which the flowers are rather larger.— Now if the figure of the plant here given is compared with this description, and with the plate of D. cornuta in this work (t. 4091), it will be seen that in all those points in which D. macrantha differs from D. megaceras, it agrees with D. cornuta, notably in the short spur, in the small petals falcately recurved, dilated at the apex, and hidden under the hood; in the oblong lip and very small broad anther: to which must be added that D. macrantha is a western plant of the Cape district itself, whereas 1). meyaceras is an eastern one, of which there are in the Kew Herbaria DECEMBER Ist, 1880. specimens from Kalberg on the Eastern frontier (from Mr. Henry Ilutton), from Natal (Mrs. Fannier), Somerset, Kaffraria (Mr. Cooper), and from the top of Bosch berg, alt. 4500 feet (Mr. MacOwan.) As to Disa macrantha of Thunberg, it is clearly a species very near to D. cornuta, if not a variety of that plant ; there are numerous specimens thus named in the Kew Herbaria, amongst them one from the sands about Salt river, near Capetown, collected by Dr. Harvey, who has appended to it a ticket with “ D. macrantha of Thunberg. Differs from D. cornuta merely in its labellum. I consider it only a variety, yet its habit is different.” Whatever the difference ‘of habit is, it is lost in the drying; for the specimen is in this state undistinguishable from D. cornuta, and, like it, has flowers not half the size of those of D. megaceras, with minute included petals. Iam indebted to Mr. Elwes for the fine flowering speci- men of M. megaceras here figured, which flowered with him to August of the present year. Descr.

One of the most beautiful of the alpine Himalayan Com- positee, but very variable and difficult to distinguish from form of neighbouring species, especially of HM. alpinus, to which small states of it approach very closely. HH. multi- radiatus is, however, in its normal state a much larger and handsomer plant, with the heads usually at least two inches in diameter, and of a fine bright purple colour. In rich moist soil old plants grow two feet high and branch very considerably, and the radical leaves disappear early, giving the plant a very different appearance from that of its younger state, in which the habit is scapigerous, and the radical leaves copious. . H. multiradiatus is a native of grassy wet pastures along thewhole length of the Himalayan range, from Kashmir, where it inhabits elevations of 7000 to 9000 feet, to Sikkim, where DECEMBER Isr, 1880. it ascends to 12,000 feet. The .specimens drawn were raised from Sikkim seed communicated by Dr. King, of the Calcutta Botanical Gardens, and flowered at Kew in June of the present year. Descr. A pubescent or hirsute herb, in a small state either six to ten inches high, with simple scape-like leafy stems, and numerous radical leaves; or tall, often two feet high, with no radical leaves and a branched leafy stem. Leaves, radical when present usually four to eight inches long, oblanceolate, narrowed into a rather long petiole, distantly toothed, three- to five-nerved; cauline ovate- lanceolate from a broad sessile and often subauricled or semi-amplexicaul base, acuminate, erect or recurved. Heads solitary on the ends of long peduncles, two to two anda half inches in diameter, very bright purple, disk yellow. Involucre broadly hemispherical; bracts slender, pubescent or tomentose, ciliate. Ligules three-fourths to one inch long, in two or three series, very slender, tube glabrous. Disk-flower glabrous. Achenes small, flattened, slightly silky; pappus scanty, hairs scabrid, with an obscure ring of small outer ones.—J. D. H.

The genus Worméa, a near ally of the familiar Hibbertias of our greenhouses, consists of about ten species of shrubs or trees with usually very handsome flowers and foliage, which extend from tropical Australia through the Malay Islands and Southern India to the Seychelles. Though known in Indian Botanic Gardens, the present is the only one that to our knowledge has ever flowered in Europe. It is closely allied to W. subsessilis of Miquel, figured in the Annals of the Leyden Botanical Museum (vol. i. p. 315, Tab. IX.), but that has larger toothed leaves, flowers five inches in diameter, and very broadly obovate petals without the hollow disk and broad crenate margins of this. Coming from the same country, I was at first disposed to regard these species as identical, but as the dried specimens from Banka, sent from the Leyden Museum to Kew Herbarium, and others gathered in Borneo confirm the accuracy of Miquel’s plate, which is, moreover, copied from a drawing taken from life, I am compelled to keep them distinct. W. Burbidgei is a native of Northern Borneo, where it was discovered by the intelligent and successful collector whose name it bears when exploring the Bornean forests DECEMBER Ist, 1880. for Messrs. Veitch. Flowers of it were preserved, and are _ now in the Kew Herbarium, and the living plant from which | the drawing is made is in the collection of its importers, with whom it flowered in July of the present year. _ Drscr. A glabrous shrub; branches terete. Leaves eight to ten inches long, almost exactly elliptic, base con- tracted and decurrent as a very broad complicate petiole one to one and a half inches long, which expands and is stem-clasping at the base, margins nearly entire or very obscurely waved, upper surface deep green, raised between the eighteen to twenty spreading nerves, which, as well as the midrib, are very prominent beneath. Flowers three inches in diameter, subcymose on a simple peduncle two to four inches long, very shortly pedicelled. Sepals nearly orbicular, very concave, coriaceous, green. Petals pale golden-yellow, obovate-oblong, disk hollowed, margins broadly undulate. Flowers very many, almost white ; anthers almost filiform, with terminal pores. Ovary broadly ovoid, of seven carpels with as many filiform flexuous stigmas.—J. D.
