Bateman. , ins _ For the opportunity of figuring this fine addition to the re genus Lissochilus we are indebted to J. B. Horsfall, Esq., M of Bellamour Hall, Staffordshire, to whom it was sent (in 1§ _ from the Old Calabar River, by Mr. S. Cheetham. It flowerec _ in October last.in Mr. Horsfall’s collection, treated as a wal _ terrestrial Orchid. In habit and in general appearance it bears’ _ some resemblance to the well-known Phajus grandifolius (Bletia Tankerviilia), but thestructure of the flowers is altogether dif- — ferent. Perhaps its nearest affinity is with another charming — _ species of Lissochilus, L. roseus, also a West African plant, but _ which, it is much to be regretted, has long since disappeared __ from our collections. May we not hope that the evidence now afforded of the beauty of certain West African Orchids may lead to increased efforts for the introduction of additional species on he part of those who, like Mr. Horsfall, have at their commat peculiar facilities for obtaining the natural productions of countries in question? For even if it be true that a large portion of the Orchids of intertropical. Africa are unattract * - JaNuaRY Ist, 1865. * there are others—some of the Augreca for example—that are ~ now as highly prized as any plants of their order. And to these ‘many splendid additions would doubtless be made, could we but obtain a few collections from the Niger and other mighty streams that water the richest portions of the African continent. The head-waters of the Nile would also contribute their quota, for among the limited collection of specimens brought home by Captains Speke and Grant, there exists a remarkable Angrecum _ which in the length of its tails might vie with the well-known A. caudatum. Some thirty years ago the name of Mr. Horsfall’s excellent father might be frequently met with in the pages of the ‘ Bota- nical Magazine,’ in connection with divers plants that he had the honour of introducing to this country, among which the still popular Jpomea Horsfallii may be cited as not the least remark- able. And it is with no ordinary pleasure that I now dedicate ‘to the worthy son of a worthy sire the beautiful plant that is _ figured in the accompanying Plate, and which he has been the. means of securing to our gardens.—J.

Dr. Harvey, who alone has described and figured this charm- ing tree or shrub, states the height of it at S-10 feet. Our plant has in two years’ time attained that height, from the period of sowing the seeds, which we received from Dr. Harvey. It has been recently discovered in South Africa by Mr. J. M‘Ken, JANUARY Ist, 1865. in Zulu-land; and at Klip-River, Natal, by Mr. W. 'T. Gerrard, who named it in compliment to Miss Burgess, of Birkenhead. The genus Dombeya is a very beautiful one, almost peculiar to tropical Africa and its eastern islands, but scarcely extending so far south as the Cape of Good Hope. Three species, however, are described by Dr. Harvey, in his admirable ‘ Flora Capensis,’ as inhabiting Uitenhage and Natal, in the first volume; and three more appeared in the Supplement to the second volume. The author anticipates the discovery of others in the Natal dis- trict, but, as he justly observes, scarcely one from them finer than this. Its large fragrant flowers appeared with us in August. Descr. Our plant in the conservatory of Kew promises to be arborescent, which, in little more than two years raised from the seed, is ten feet high, moderately branched at the summit; the younger branches herbaceous, terete, and downy. Leaves alter- nate, long-petiolate, six inches to a span long, cordately five-lobed, pubescently hirsute; the /odes acute, coarsely and unequally ser- rated, terminal one acuminate. Sfipules ovate, acuminate, at length deciduous. Peduncle in our plant axillary, longer than the petiole, downy, corymbose, bearing many large white flowers, roseate in the disk, with the same tint extending into the veins. Calyz in our plant ebracteolate, of five spreading, at length reflexed lanceolate sepals. Petals obliquely subdeltoid, very obtuse, concave. Column of stamens short and cup-shaped, terminating in five s/eri/e, long, linear-spathulate stamens, be- tween which, but not half their length, are generally three (some- times two) fertile ones. Filaments filiform. Anthers oblong, two-celled. Ovary globose, downy. Style filiform, shorter than the sterile filaments, but longer than the fertile ones. Stigmas five, linear, reflexed, downy.—/.

Bateman. This new Dendrobium was sent (in 1862) from Moulmein by the Rev. C. S. P. Parish to Messrs. Hugh Low and Co., of the Clapton Nursery, in whose establishment, as also in the collec- tions of Mr. Rucker and Mr. Day, it has flowered beautifully during the past season. At first sight it appears to bear a cer- tain amount of resemblance to D. xodile, but it is im reality per- fectly distinct. Even when out of flower it is readily distinguished by its thick, clumsy, leafless stems, which are bent downwards in a stiff ungainly manner, while the stems of D. nodie and D. moniliforme hold themselves erect, and taper gracefully towards the base. ‘The flowering-season of these latter species is likewise different, being confined to the winter months, whereas D. Parishit blossoms in summer. A glance at the recent volumes of the ‘ Botanical Magazine’ will show the large number of new and beautiful Orchids that have been secured to the collections of this country through the zeal and enterprise of Mr. Parish, whose eye seems to be ever ready to detect any new forms amid the striking vegetation of the rich country that is now the scene of his missionary labours. It is, however, among the Dendrobia that his most remarkable discoveries have been made, and I have therefore a peculiar pleasure in associating his name with a new species of the beau- tiful genus that owes so much to his diligent researches.—J/. B. JANUARY Ist, 1865. Descr. Stems a foot or more long, extremely thick throughout their whole length, bent downwards, covered, when young, with thin, white membranes, which fall off the second year. Leaves stiff and leathery, from two to four inches long, blunt and usu- ally a little notched at the ends, falling off the first year. Flowers in twos or (more rarely) in threes, produced freely on a short spurious raceme, along more than half the entire length of the stems. Pedicels nearly two inches long. Sepals half the length of the pedicels, oblong-lanceolate, acute, of a beautiful light-rose colour, except at the base, where the rose-colour fades into white. Petals same colour as the sepals, than which they are slightly broader, unguiculate, ovate, somewhat obtuse. Lip entire, shorter than the sepals, and (when spread flat) nearly round, apiculate, hooded, downy in front and at the edges, with rich purple inte- rior markings on either side the throat, and a lighter tint along its centre and at the recurved apex.—J.

Cultivated, as no doubt it will soon be, as a greenhouse climber, it cannot fail to be very attractive; and let it be remembered that it is of such rapid growth, that in its native quebradas of Chili, it climbs to the tops of the highest trees, as stated by Bridges and M. Gay. It has flowered for the first time at the Chelsea Nursery, in July, 1864. Descr. A lofty perennial clméer, with flexuose branches, which are striated and downy, younger ones often very flexuose.

This very handsome species of the very beautiful genus Swain- sonia has been raised from seeds sent from Western Australia by Mr. Wm. Thompson, of Ipswich, from whom we received specimens in the summer of 1864. Our earliest knowledge of it was from specimens gathered by Mr. Bynoe at Depuech Island, and abundantly in sterile places in Nichol Bay, during Gregory and Ridley’s Exploring Expedition, both in North Australia. Drummond also appears to have gathered it in West Australia (as it has been raised from his seeds, and first blos- somed in 1863), and Mr. Oldfield gathered it in the Murchison river. Of this genus (including Cyclogyne of Bentham and Diplolo- bium of Mueller) fourteen species have been published by Mr. JANUARY IsT, 1865. Bentham, in the second volume of his valuable ‘ Flora Australi- ensis ;’ of these, two are already figured in this work, viz. S. co- ronillefolia, Tab. 1725, and S. Greyana, Tab. 4416. In the copiously-flowered racemes and in the colour of the corollas the present will bear comparison with any known species, and cannot fail to prove a great ornament to our greenhouses. Fig. 1.

EpIpENDRUM dichromum. Lindl. Fol. Orch., et in Bot. Reg. 1843, Misc. 119. This charming Zpidendrum was imported last year from Bahia by Messrs. Hugh Low and Co., of the Clapton Nursery, through whom it speedily found its way into all the principal collections in the neighbourhood of London. In many of these it has already flowered, and I was myself fortunate enough to see it in bloom last autumn in Mr. Bassett’s garden, as well as at the establishments of Mr. Williams, of Holloway, and of Messrs. Lee, of Hammersmith. In each case the variety was ditferent, the sepals and petals in Mr. Bassett’s plant being of a pale rose-colour, in that of Mr. Williams they were nearly white, while in Messrs. Lee’s specimen—from which the figure is de- rived—both tints were combined with such pleasing effect as to merit the distinctive appellation of ‘amadie’ which I have ven- tured to add to the specific name. Mr. Low’s collector found the plant in exposed places on the margin of rivers, establishing itself on the branches of low straggling bushes, and sending its roots down into the sand amidst which they grew. ‘Taking their cue from these pecu- liarities in its habit in a wild state some cultivators are attempt- ing to grow the species potted in sand, but I scarcely expect they will succeed. In the meantime it seems to thrive upon a block of wood or in a pot nearly filled with potsherds. It will FEBRUARY IsT, 1865. + bear exposure to the light, and, while growing, must have a d amount of heat. When I first examined the plant I thought it was probably new, but I am now satisfied that Professor Reichenbach was right in referring it to the £. dichromum of Lindley, in despite of some minor discrepancies, for which its tendency to run into varieties may readily account. The species of Hpidendrum are not usually popular with culti- vators, few of them possessing much brilliancy of colour; but the present subject is a notable exception—rivalling, as it does, the best of the Barkertas—and there are others of equal or greater beauty still to introduce. Among the latter I would specially instance Z. erubescens, which produces a panicle nearly four times the size of the one represented in the Plate, and with flowers of a similar hue. It is a native of Oaxaca, whence liv- ing specimens were imported more than twenty years ago, they all however died because they were kept too warm. Surely an attempt ought to be made to re-introduce so desirable a Ho vag we should now be able to manage with perfect ease.— Descr. Pseudobulbs clustered, from three to six inches long, smooth, round, ovate-oblong. eaves two or three on each bulb, strap-shaped, from six inches to a foot or more in length, rather blunt at the ends, erect, and rigid. Scape, in the wild specimens, three feet high or more, bearing a many-flowered panicle. The flowers vary both in their size and tints, some being as large and as brilliantly rose-coloured as the specimens represented in the Plate, while others are almost entire y white, and considerably smaller. Sepa/s about an inch long, linear- lanceolate, rather sharp at the ends; petals wider than the sepals, and obovate. Lip deeply three-lobed, the middle lobe obcordate, with many ribs on its disk, of a beautiful deep crim- son, with light margin; the lateral lobes are shorter, spreading at the ends, white, externally turned up with purple. Column as long as the lateral lobes of the lip, bearing two short blunt wings. Fig. 1. Lip. 2. Column. 3. Pollen-masses :—all slightly magnified. t Pe ae Pt ee W. Fitch, del et lith.

The genus Morenia, next of kin to Chamedorea, Willd., was established by Ruiz and Pavon in 1794, on a small graceful Peruvian Palm; and the only species known to those authors was the MZ. fragrans. To this Martius added a second species, M. Peppigiana, figured in Mart. Palm. at tt. 140, ‘141, and which so far resembles our plant, that if I had been uninfluenced by any other authority, I should have been disposed to consi- der the two the same. He described it as scarcely differing — from M. fragrans, except in the “taller caudex and inodorous _ FEBRUARY lst, 1865. flowers.” Our present plant was received from Linden in _ 1850, named “ Chamedorea” (without locality), and has been named by Wendland Morenia Lindeniana, in our Herbarium ; but there is a Chamedorea Lindeniana, as above quoted, with- out any character or mention of country, with a reference to _ Otto and Dietr. Gartenz. 1853, n. 18. p- 139, which I have no opportunity of consulting. It is certain, however, that we _ possess specimens of this same Palm in our herbarium from _Chacapoyas, Peru (Mathews, n. 31082, “San Capilla” of the natives), Santa Martha (Purdie), and an allied plant from Sa- lango, Columbia, gathered by the late Dr. Sinclair, which Mr. Bentham has (probably correctly) named Morenia Sragrans? 1 _ think it therefore safer to consider this to be the same as the _ fragrans of Ruiz and Pavon, rather than increase the number of species dubia, which are so puzzling to the botanist. There can _ hardly be a doubt (judging from the figure) that Martius’s 7. _ Peppigiana is a closely allied plant to this; indeed, he says of it, “videtur a Morenia fragrante divisa,” but the distinctions he gives seem to be of very trifling value. Our flowering-plants are destitute of female flowers. _ It is to be regretted that these smaller Palms, which present uch graceful forms, and occupy little space, are not more culti- vated in our stoves. It is only from the living plant and correct figures that we can arrive at a knowledge of their genera and Species. _ Fig. 1. Much reduced flowering-plant. 2. Base of a pinna,—nalural size. _ 3.

Perhaps no plants require more illustration by figures than the species of a genus of which we here represent one, which we venture to consider as new. It promises to be a genus numerous in individuals, and these of a most interesting cha- racter, and of which the well-known American Aloe (Agave Americana) is the type. Travelling botanists in vain attempt to preserve specimens for the herbarium,—they cannot therefore be studied ¢here ;—and in our gardens, except in some great public establishments, few are disposed to sacrifice the space necessary for their cultivation, and they are proverbially shy of flowering, so much so, that the Agave Americana is generally and to this day — spoken of as the plant which “ flowers once in a hundred years. It is true that of late, in a German work,* a “ monographische Skizze” is given of no less than sixty-four species, apparently of those in cultivation, with brief specific characters,—a large proportion of them derived from the foliage alone, so that they * ©Wochenschrift des Vereines zur Beférderung des Gartenbaues in den K6- niglich-Preussischen Staaten, fiir Giirtnerei und Pfianzenkunde.

It is from the rich collection of succulents in the possession of our friend William Wilson Saunders, Esq., of Heathfield, Reigate. Its origin is not known, and we can only say it is probably a native of Mexico, a region so rich in species of this genus. It has flowered in the winter season, and now, January, 1865, the fruit seems fully formed, but at present quite green. Descr. Stemless. Leaves singularly spreading, nearly horizon- tally, the lowest ones lying close to the ground, one and a half to two feet long, moderately thick, glaucous, oblong-lanceolate, suddenly terminating in long purple-brown spines, nearly plane or with the spinous margins a little upturned; the spines dis- tant, from a broad base triangular, dark purple-brown. Scape, in our plant, fourteen feet long, stout in proportion, cylindrical, beset at very short intervals with erect, appressed, subulate scales, which soon become marcescent. Clusters or fascicles of flowers numerous, subglobose, densely crowded, terminating in a horizontal peduncle, four inches long, its base subtended by a large, ovate, acuminate dract deeply carinated below. Secon- dary fascicles subsessile and bracteolated at the base. Ovary one and a half inch long, green, subterete, but obscurely grooved or six-angled, crowned by the yellow /imé of four, nearly erect, acuminated segments. Stamens six, yellow; filaments equal in length with the perianth, and inserted between the segments. Anthers very large, deep-yellow, versatile. Style half the length of the filaments, terminated by a clavate stigma. Capsule (at present immature) nearly elliptical, crowned by the withered limb of the perianth. Fig. 1.

Hugh Low and Co. have Jately re-introduced, is now found to grow freely and flower profusely under the most ordinary treatment.

The leaves on the older branches attain a length of three to three and a half inches, and are never cordate at the base; those on the flowering-branches (or rather leafy and drooping panicles) are smaller and usually broader in proportion ; these leaves become dracés on the ultimate branch- lets or peduncles. The species is by far the most beautiful known to us. Fig. 1. Corolla, laid open. 2. Calyx and pistil. 3. Transverse section of ovary :—magnified. . ay ple AS NCD RE: W Fitch, del et lith.

When we described our Arisema Murrayi, at Tab. 4388 of this work, we noticed that Blume, in his ‘Rumphia,’ had re- corded thirty-one species, mostly of Asiatic origin. Schott, in his more recent ‘Prodromus Systematis Aroidearum,’ has in- creased the list to eighty-one, including certain doubtful species. The one here represented is a native of the Nilgherries, and it has lately been found by Thwaites in Ceylon, whence the tubers were kindly communicated to us. It is described as there inhabiting the Central Province of the island, at an eleva- tion of 4000-6000 feet. The large tuberous roots are used as FEBRUARY Ist, 1865. a medicine by the Cingalese, and sometimes called ‘“ Snakeroot.”’ It is by the root that they probably increase in their native re- gions, for in our species (4. Murray, above mentioned, and in the singular 4. precor, Tab. nostr. 5267, as well as in the pre- sent instance) no pistils are produced. The specific name papillosum is probably given by the author on account of the papilliform abortive pistils on the spadix. Fig. 1. Much reduced figure of an entire plant. 2. Tuber. 3.

NosTR. 5497.) Superior as this Aroideous plant is, in point of beauty, to that we have figured at Tab. 5376, it cannot but be considered a more highly-coloured and variegated variety of it. Its genus Is unquestionably the same; but whether we have done right in referring our A/ocasia Lowii and A. metallica (Tab. nostr. 5190) both to the genus A/ocasia, we must leave to the judgment of those who are more familiar with this difficult family of plants than we are ourselves. Certain it is that we have erred in con- sidering our metallica to be the same as the plant of that name: in Schott’s ‘ Synopsis Aroidearum,’ for the author has lately, in MARCH lst, 1865, his ‘ Prodromus Systematis Aroidearum,’ abolished that species and referred it as a mere variety (‘“‘colore plus minusve atro- purpureo”’) of the well-known Alocasia Indica, Schott (Arum Indicum of Roxburgh). Independent of other most important characters, the stigma of our 4. metallica (and it is the same in A. Lowii) is remarkable, no less for its great size in proportion to the ovary than for its being deeply divided into three to five spreading acute lobes; whereas in A. izodora the stigma is de- presso-hemisphericum, and is considered to be characteristic of the genus by that great writer on Aroidee, Schott. Let it be observed that both these splendid species we are now considering are inhabitants of the same country, Borneo, (perhaps now the finest country in the world for the researches of the botanist and the horticulturist,) and both of them were intro- duced by Messrs. Low, of Clapton. The plant here figured was communicated to us by Messrs. E. G. Henderson and Son, of Wellington Road, St. John’s Wood, in April, 1864. Descr. Our plant was a solitary one, not (as yet at least) growing in dense tufts, like our Alocasia metallica, and it pos- sessed but one leaf; its petiole springs with a broad base directly from the summit of the rhizome, annulated at the summit, and is a foot and a half high, green, purplish upwards, ringed and spotted with darker lines, shortly sheathing at the base. ‘The blade of the leaf is fifteen inches long, peltate, sagittato-ovate, or subcordate, extremely handsome in colour, very full, dark- green above, edged with a thickened whitish margin, while the costa and primary veins are enclosed as it were in broad bands of a whitish or sea-green colour, melting into the dark-green or sending out slender white anastomosing vein/eds, while the whole underside is rich purple. The sizws of the lobes is very deep ; the Jobes are subparallel (not spreading), and have each a strong branch of the stout costa running down much nearer the inner than the outer margin. The primary veins or costules are remote and horizontal, but only on the outer side of the two branches just spoken of; on the rest of the leaf they are on both sides and nearly opposite. Scape from the short sheath at the base of the petiole, and very much shorter than it, pale-green speckled with dark purple, and clothed, for nearly its whole length, with sheathing pale-coloured dracts, elegantly lined and dotted with’ red. Spatha four and a half inches long, globose and green at the base, the rest cucullato-cymbiform, yellowish-white tinged with red. Spadiz sessile or nearly so, the lowest portion clothed with pistils. Ovary globose. Style very short : stigma very large, of four to five star-like rays; between these and the anthers is a contraction occupied by glands, of which the inferior are pro- bably abortive pistils, whilst the upper ones seem to pass gradually _ Into the anthers, which occupy the greater portion of the centre of the spadix, and are thick and fleshy, discoid, with six to eight oblong cells at the sides, opening by pores at the apex or margin of the crenated disk. The apex of the spadix (or appendage) is a cylindrical fleshy mass, longitudinally wrinkled. Fig. 1. Spadix,—natural size. 2. Pistils. 8.

At first sight this rare and beautiful plant might be mistaken for a large variety of another Lelia, with which we have been long familiar under the various names of Cattleya pumila, C. mar- ginata, or C. Pinelli, but it is in reality perfectly distinct. Pro- fessor Reichenbach was the first to distinguish it, and he has given a most faithful representation in one of the Plates of his ‘Xenia Orchidacea,’ his specimens having been obtained from the rich collection of Consul Schiller, of Hamburg. In this country the plant is still extremely rare, and I am not aware of its having bloomed except in the collections of Mr. Day and Mr. Marshall. It was from a plant that flowered finely in the garden of the latter gentleman that the accompanying figure was prepared. L. prestans comes from the island of St. Catherine, and should be treated like other Brazilian Lelias and Cattleyas from the same locality ; but it prefers a block of hard wood to a pot, and it should always be placed near the glass.

Horticole, Aug. 1864, t, 409 (foliage only). Amidst the many coloured-leaved plants which have been of late introduced into ornamental gardening, few are more striking than the one we now represent, and few have excited more in- terest among horticulturists, as may be inferred from the fact of ‘its having been figured in two horticultural works before the flowers were known to the authors, and a first-class certificate | was awarded to Mr. Herbst, of the Kew Nursery, Richmond, who introduced it to this country from the river Plate, South Brazil. Mr. Lemaire gives Para, in North Brazil, at the mouth of the Amazon, as its native country, whilst I myself possess a fine native specimen, with all the characters of the cultivated one, from Moyabamba, in the Andes of Peru, situated on a small MARCH Ist, 1865. river of the same name, not far from the sources of the Amazon, gathered by Mr. Mathews (his n. 1616). It is not a little re- markable, considering how distinct these three localities are from each other, and well as they have been explored by many and most able botanists, it should never have found a describer till now that it has thus come to our knowledge through our Floral Gardens. Martius, who made the Amaranthacee of Brazil his ‘special study, and Spruce, who was indefatigable in his researches upon the Amazon river and its tributaries, seem never to have met with it;* and the specimens in my Herbarium, where it has been for these thirty years seem wholly to have escaped the notice of the author of the Amaranthacee in De Candolle’s ‘ Pro- dromus, who had access to all of the order in our possession. It is therefore not without reason that we dedicate the plant to Mr. Herbst. ‘The flowering specimen was, with many others, reared by him in the autumn and winter of 1864-5. As the Iresine Herbstii is likely to become of great interest as a bedding-out plant, we shall subjoin an extract from Mr. Herbst’s communication to the ‘ Floral Magazine :'-—* It attains a height of from twelve to eighteen inches, and is without any trouble grown into a perfect specimen of the most globular form, as it produces a branch from the axil of every leaf. In a house too warm and close it no doubt grows taller, but even the stopping of the terminal shoot would make it branch very easily. The stem and branches are of a most beautiful, almost transparent carmine, while the leaf itself, strongly bilobed, is of a purplish- crimson underneath, dark maroon on its upper side, with its many broad ribs of a very prominent carmine. ‘There is not a green spot on the whole plant, and whether placed in the shade or in the most brilliant sunshine, it produces a most admirable contrast with plants of a lighter colour. It has neither the gloomy appearance of the Perzl/a nor the woolly leaf of the Coleus, and is by no means so susceptible of cold and dampness combined as this latter plant. Another advantage it has is, that it does not flower either out-of-doors or in a warm greenhouse, where I have introduced several strong plants on purpose to induce it to flower, but without success,” Since that time, however, Mr. Herbst has, by great care, caused plants to produce the panicles of flowers, which to a botanical eye detract in no way from the charm of the plant, as may be seen by our figure.

A native of the Malay Islands, and probably not uncommon there, especially in the Moluccas, figured (but upon a reduced size) by old Rumphius, and more recently and more accurately by Dr. Wight, and by the second Rumphius (Blume). The whole- coloured variety has been long cultivated in our gardens, but the spotted-leaved variety has only recently been imported in Euro- MARCH Ist, 1865. pean gardens from Manilla by Messrs. Veitch and Son. We think it more than probable that this state of the plaut is the 4. commu- tatum of Schott, Synops. p. 123, for his description sufficiently agrees with our plant, as does the analysis of the fructification in his fine work on the ‘ Gefiera Aroidearum.’ The difference of the venation, on which he lays so much stress, we find to be vari- able on the same plant, and even on the same leaf. ‘The plant is a graceful one, and in age the stem-like caudex increases con- siderably in length. It has been generally considered that plants with gay-coloured or variegated foliage are pre-eminently natives of the Malay Is- lands and that region, but it will probably be found that those of tropical America are equally deserving of cultivation. On in- quiring of my friend Mr. Spruce if he did not meet at Paré or on the Moyobansha with the fine-coloured Jresine Herdstii, figured in our present number of the Magazine, he says, “I have some recollection of seeing an Amaranthacea very like it, but I did not gather it, because it was out of flower;” and he adds, “You know that when I left England in 1849 nobody cared for painted- leaved plants, and it was not till I got to the western side of the Andes that I learnt there was such a rage for them. I then re- membered how many striped and spotted leaves I had seen of Scitaminee, Aroidea, Cissi, etc., in the Amazon Valley, and had admired their beauty, but never dreamt that anybody would care for them in England. For the same reason Martius might easily pass over a painted-leaved Amaranth in South Brazil, where you say he ought to have seen it.” Fig. 1. Male flower, a stamen. 2.

Although introduced to our collections about the year 1850, no coloured representation has yet appeared of this beautiful plant, which is by far the most ornamental species of the sin- gular genus to which it belongs. It was discovered by Warsze- wicz in Nicaragua, and was probably distributed under the hammer of Mr. Stevens soon after its arrival in this country, but it is still exceedingly rare. Indeed, but for the care bestowed upon the plant at Oulton Park, where it originally flowered, and from whence, through the kindness of Sir Philip Egerton, my own specimens were derived, it would in all probability ere this have been lost to our gardens. Nothing can be simpler than its cultivation, but it requires a pot and a fair amount of heat, and, being a rapid grower, it should be broken up, like the Gongoras and Stanhopeas, every second or third year. It flowers abundantly during the summer months. There is a great family likeness among the Acroperas, and therefore, al- though botanically distinct, it is not desirable to attempt to cul- tivate them all. Where a selection is made, 4. Batemanni and _ A. Armeniaca are decidedly the best, and of these two the last is brighter in its colouring, and larger and handsomer in all its parts.—J. B. Fig. 1. Side view of a flower. 2.

It seems quite to accord in habit and in generic character with the Billbergia cruenta of Graham, in Bot. Mag. t. 2892, but is far more beautiful in the colour of the corollas, and still more of the floral leaves. It is to be regretted that no locality has been given with the plant, but no doubt it is a native of tropical America, where the spe- cies of the family to which it belongs are great ornaments to the trunks of the forest trees, and where they are often intermixed APRIL Ist, 1865. with equally beautiful Orchidaceous plants. ‘The present species has many points in common with Jacquin’s Zid/andsia ligulata (native of Martinique), of his Select.

Spzte terminal, sessile, three inches long, amentiform, terminal, but so much shorter than the outer foliage, that it could not easily be seen but for the presence of the richly-coloured, erect floral leaves, longer, indeed, than the spike, but much shorter than the outer or cauline Jeaves.

The genus As/elia of Banks and Solander is a very peculiar one, native exclusively of the southern hemisphere, which End- licher places in a croup of Juncee he calls “ Asteliez, while Dr. Hooker refers it to Ziliacee, near Phormium and Cordyline, and of which five species are recorded as natives of New Zea- land, one in Oahu, one in Fuegia, and another in ‘Tasmania. “ All,” Dr. Hooker observes, “are densely-tufted herbs, with a short, creeping rhizome, with very long leaves, more or less covered with shaggy wool or silvery hairs. ‘The large kinds form a conspicuous feature on the lofty trees of New Zealand forests, where, growing epiphytically on branches, they resemble APRIL 'sr, 1865. gigantic birds’-nests. The smaller kinds inhabit marshes. We have already published one species from New Zealand at Tab. 5175 of this Magazine, and we have now the pleasure of figur- ing a second, also from New Zealand, where it is common on trunks of trees in the northern and middle islands, for which our gardens are indebted to the late lamented Dr. Sinclair. It has flowered copiously with us in a cool greenhouse. Descr. Dr. Hooker gives the following account, drawn up from living plants in New Zealand:—“A very large species. Leaves two feet long, spreading and recurved, three inches broad at the base, and there clothed with dense, snow-white, silky, villous wool, glabrous above, silky below, with three strong nerves. Male: Scape stout. Panicle six to eighteen inches long; éranches, with the flowers included, one inch across. Flowers very crowded, closely pedicelled. Perianth very large, half an inch long, membranous ; segments linear, obtuse, silky externally. Filaments half an inch long; anthers linear-oblong. Female: Scape stout, curved. Panicle with very long, slender (rarely short, stout) dranches, eight to twelve inches long. Flowers close-set, fascicled or whorled ; pedicels slender, half an inch long. Perianth much smaller and more scariose than on the male; ¢ube hemispheric; segments recurved. Ovary glo- bose, three-celled ; s/y/e straight.” Our principal figure repre- sents the male plant.

This beautiful Cattleya was sent many years ago to Mr. Rucker from New Granada, by one of his correspondents who met with a solitary plant of it on the upper waters of the Rio Magdalena. It soon flowered in Mr. Rucker’s collection, and the specimens then produced were forwarded to Dr. Lindley who, being satisfied that it was a new species, gave it the appro- priate name of C. quadricolor, in allusion to the four colours, white, yellow, lilac, and purple, that are observable in its blos- soms. ‘I'he latter are produced in the winter months, and con- tinue in perfection a long time, but they do not spread them- selves out so freely as those of most other Cattleyas do. When I first examined the flowers of C. guadricolor I felt no doubt that Dr. Lindley was right in regarding it as new; and even to the present time I have seen no Cattleya with such closely imbricated white flowers, nor are its long upright nar- row pseudobulbous stems to be matched among the extensive importations that the Horticultural Society, the Messrs. Low, and others have received from the country in which it was ori- ginally found. Yet this very circumstance suggests a doubt as to whether it may not ultimately prove to be what botanists call a peloria (i.e. a monster) of some other species, for if it were really an independent form, it seems scarcely credible that none of the collectors now in New Granada should have met with it. APRIL Ist, 1865. But even if admitted to be a pe/oria, to what species must it be referred? The answer to this question opens a rather extensive field of inquiry, and implicates a large number of reputed spe- cies, including C. /abiata, C. Mossia, C. pallida, C. Warszewiczii, C. Trianei, and C. Wageneri, which are found distributed over a vast range of territory extending from the heart of Mexico to the capital of Brazil. The first on the list, C. /adiata, was found some thirty or forty years ago—where alas! it is not to be found now—on the well-known Organ Mountains in the vici- nity of Rio Janeiro. The next, C. Mossig, was found on the Spanish main, and as it always bloomed in the spring or sum- mer, and had never more than two or three flowers on a scape, it was long considered distinct from C. /adiata, which had inva- riably bloomed in November, and produced double the number of flowers. But last June I received luxuriant specimens of what was undoubtedly C. /adiata from the garden of the Bishop of Winchester, while plants have been imported of C. Mossie producing four to six flowers on a scape, and thus the most marked distinctions between the two supposed species have entirely disappeared. Of C. pallida a solitary plant was found by Hartweg on his way to Oaxaca; this has recently flowered at Knypersley, and proves to be, as Reichenbach suspected, identical with the C. Warszewiczii delicata of Mr. Warner, which was found by the traveller whose name it bears in the interior of New Granada, ‘This again is indistinguishable, except in colour, from C. Wageneri of the same country, and which has very naturally been regarded as nothing but a white variety of C. Mossie. Finally Mr. Weir, the zealous collector of the Horti- cultural Society, mentions in one of his letters from Bogoté, that he met with innumerable varieties—white, lilac, and rose—of a beautiful Cattleya that. he gathered in that neighbourhood, and the dried specimens of which exactly resemble the flowers of C. labiata, C. Trianei, and C. Warszewiczit. From a collation of the facts before us, there would seem to be at least a high probability that all the six so-called species above referred to are in reality varieties of a single form that spreads itself—like prdendrum ciliare and E. cochleatum—over the whole Orchid- growing region of tropical America. Whether or no C. guadri- color itself will have to be added to the list of cancelled species, 1S a question that time only can determine. Meanwhile the hybridizer plies his trade, and will speedily render “‘ worse con- founded” that confusion” which is sufficiently perplexing, even as it comes to us from the hand of nature.—J/. B.

The genus Masdevallia was specially selected by Dr. Lindley, when announcing the preparation of his ‘ Folia Orchidacea,’ to illustrate the astonishing progress that had been made in our knowledge of Orchids since the publication, a quarter of a cen- tury before, of his ‘Genera and Species.’ In the latter work only three Masdevallias were described, though the number had risen to nearly forty at the time above referred to, and it has been largely augmented since then. But however plentiful the Mas- devallias in their native wilds, they have made their way slowly and reluctantly to the gardens of Europe, in which scarcely half- _a-dozen—and these among the most insignificant of the race— have as yet produced flowers. The species, however, that is re- presented in the accompanying Plate will convey a more ade- quate notion of the attractiveness of its family, and may well challenge the attention, not of the botanist merely, but of every cultivator of rare and beautiful plants. ; Masdevallia Tovarensis, as its name implies, is a native of Tovar, in Columbia, where it was discovered at an elevation of APRIL Ist, 1865. several thousand feet, and sent to Germany many years ago, and it was from the latter country that Mr. Rucker received the plant from which, in November last, the present figure was ob- tained. In Mr. Rucker’s collection it passed under the name of AL, candida, which, as Reichenbach has correctly pointed out, was erroneously given by the late Dr. Klotzsch to a plant that had already been described as JZ. Tovarensis. To add to the confusion, there exists in the collection of Lady Dorothy Nevill a plant under the name of JZ. Zovarensis, which is altogether different from the species now described, and of which I hope to give some account at a future time. Nearly all the Masdevallias may be classed among cool, and many of the species among the very coolest Orchids, being chiefly found at a great elevation on the Andes of New Gra- nada and Peru. Nothing can be easier than their cultivation, if the conditions of low temperature and almost constant hu- midity to which they are accustomed in their native habitats, be duly imitated. It is hoped that collectors may be induced to make the introduction of a number of these lovely plants a special object, for a group of twenty or thirty kinds might be grown in a space that would be insufficient to accommodate a single specimen of some of the larger Orchids, and with nearly half the amount of heat. Among the species particularly worth searching for, I would notice IZ. rosea, that covers the slopes .of the Popayan Alps with flowers larger than those of IZ. candida, and of the loveliest purple-rose colour; J. racemosa, from the same country, with spikes a foot long, of flowers larger than any Burlingtonia, and of the most vivid scarlet; and JM. ele- Phanticeps, from New Granada, with gold and purple blossoms six Inches long, and the arrangement of which vindicates the propriety of the singular name given to it by Professor Reichen- bach (in whose ‘ Xenia’ it is admirably figured), for it offers an almost exact similitude to an elephant’s head, with tusks and trunk complete! _ Another species, M. coccinea, a worthy rival to the best of the above, is happily already among us in a living state, having been brought over in a cigar-box by Warszewicz, and thus saved from the risk of decay which delicate plants incur if huddled together with those that are more robust. A neglect of this precaution caused the death of many splendid masses of MW. ele- phanticeps that were imported by Messrs. Low and others during the last year.—/J. B. Descr.

Species inter se dificilius distin- guende.” At the time of the publication of his valuable Mono- graph of Melastomacee, M. Naudin did not seem to be ac- quainted with this species; but we have received authentic specimens of what he considers to be it from M. ‘Triana, from Granada, and this we have no difficulty in determining to be the same specifically as ours, and of which we have copious native specimens from Professor Jameson, of Quito, gathered in APRIL lst, 1865. - the lofty mountains of Ecuador (alt. 7-9000 feet), and from Mr. M‘Lean, from Vita, Peru, and from Hartweg, New Granada, n. 1006. De Candolle, however, and Naudin consider it to be identical with the Rhexia dicrananthera, Ruiz and Pavon, 1. c., which is the authority for the Arthrostemma dicrananthera of De Candolle. It may be so, but Ruiz and Pavon’s figure re- presents a more sturdy plant, with much smaller leaves, exactly and broadly ovate, obtuse at the base (“ut plurimum pollicaria, latitudine semipollicaria”’), which leads me to doubt of the cor- rectness of that reference. It is an excessively pretty plant, deserving a place in every warm greenhouse. Our plants were reared from seed received from Professor Jameson by Isaac Anderson, Esq., of Hay Lodge, Trinity, Edinburgh, a most successful cultivator of plants, espe- cially those which he raises from seeds sent him by Professor Jameson, from the lofty Andes of South America. he species flowered abundantly with us in October, 1864.

Veitch in the Philippine Islands, and by him sent to his father’s esta- blishment at Chelsea, where it bloomed for the first time in March last. It is most nearly related to C. Sfonei, the only other species known to have glossy leaves, but differs from it in the form and colour of its lip, which is small and of a dirty yellow, while that of C. Stonez is large, with a pink front on a white ground ; the petals, too, of C. Stonei are not twisted, and only twice the length of the sepals, while in C. Zevigatum they are much twisted, and at least four times the length of the sepals. Again in C. Stonei the dorsal sepal is striped on the outside with crimson, but is white within, whereas in C. /evigatum the crim- son stripes are all on the inside. Mr. Veitch found C. evigatum established upon the roots of _ the well-known Vanda Batemanni, to obtain which was one main object of his voyage, though he sought for it long in vain, and had almost begun to despair of ever meeting with it, when running his boat one day ashore in the bay of a small island, he was delighted and astonished to find the rocks by the coast covered with huge masses of the plant of which he was in quest. As the Vanda affects a warm situation, the Cypripedium should be treated in the same way. At Chelsea it is placed in the East India house, where it grows freely. MAY Ist, 1865. Descr.

In the present confused state of the genera of Acanthacea, it is not easy to determine that of this plant: that it can have nothing to do with Hranthemum is ob- vious ; it accords pretty well with the characters of Hypestes, in which we place it, and of which there are many African and Madagascar species.

The Aucuba Japonica affords a singular instance of the great length of time that may elapse between the first information of a remarkable plant being received, and an accurate knowledge of it acquired. This plant was first introduced from Japan in 1783 by a Mr. John Greeffer (see Bot. Mag. t. 1197), but only the female plant, and this under the well-known variegated form. From that one plant, the millions now scattered over Europe and ‘America have been derived; but it is only within the last few years that, thanks to the indefatigable Mr. Fortune, the male plant, and in its native unvariegated form, has reached us. This, which we here figure, differs in no respect except colour from the cultivated plant, and except that it bears abundantly hand- some scarlet berries, it would have no chance of rivalling in po- pular estimation the variegated form. Two other lessons may be learned from the history of the MAY Ist, 1865. Aucuba : first, that varieties may be, and indeed in many cases are, as permanent as species. Of variations, that consisting in discolo- ration of the foliage is supposed to be the least characteristic and permanent, and yet the ducuba has retained this character un- changed through upwards of eighty years in Europe, America, and the colonies ; and probably through many centuries in Japan. Secondly, that though discoloration is usually attributed to dis- ease, this may not be so really; for certainly the Awcuba has shown no sign of deterioration since it was first introduced. Several curious problems remain to be solved with regard to the Aucuba, such as, whether the old variegated form will seed well if impregnated by pollen of the uncoloured, and whether its seedling will be as strong and healthy as its offspring by cut- tings; whether the uncoloured form will ever sport and become variegated, as many plants are apt to do on damp clay soils; and whether the offspring of the uncolored and coloured forms will tend most to the one or the other of its parents. It is curious to read that the Auvcvda, when first introduced, was treated as a stove-plant, and even as late as 1809 was often cultivated in a greenhouse, where the leaves are described as being of a fuller green than when cultivated out-of-doors. The uncoloured female Aucvéa is now common in our collec- tions: for the magnificent fruiting branch we have figured we are indebted to Messrs. Standish’s Ascot Nursery. _ Wig. 1. Female flower. 2.

Bateman. This new Cypripedium differs entirely from all the species of that extensive genus at present known to us. Its leaves are compactly arranged, and being beautifully mottled on their upper surface and of a rich reddish-purple below, they contrast agreeably with the pale-primrose tint of the flowers, two of which are borne on a short hairy scape. It is a native of Moul- mein, where it was found growing on limestone rocks by the Rev. C. Parish, who forwarded a careful drawing to Sir William Hooker. Colonel Benson also found it in the same localities, and dispatched living plants to Kew, where they are now thriv- ing. Other specimens were received at the Clapton Nursery from Mr. Parish, one of which having found its way into Mr. Rucker’s collection, flowered there early in the present year, while another blossomed in the collection of Mr. Day. Both were exhibited at the Tuesday meetings of the Horticultural So- ciety at South Kensington, and justly attracted a good deal of attention. The drawing was taken from Mr. Rucker’s specimen. C. concolor seems to grow and flower as freely, and to be ma- naged with as little difficulty as the other Indian Cypripedia. Desor. Leaves four or five together, lying nearly flat, oblong, channelled, beautifully mottled on their upper surface with light- green on a darker ground, but of a reddish-purple underneath ; they are from four to six inches long.

Of the most beautiful and singular genus Vellosia, the pre- sent is the only species which, in so far as we are aware, has flowered in this country. The seeds were sent by the late Mr. Gardner, during his Brazilian journey, to the Glasnevin Gardens of Dublin, where a plant flowered this year, under the skilful management of Dr. Moore. The species 1s probably widely distributed ; it appears to be common about Rio de Janeiro, whence we have specimens from Mr. Graham, Mr. Boog, and Mr. Gardner himself (p. 132). Sprengel gives as synonyms the V. aloefolia, Mart., and V. tubifora, H. B. and & (Radia tubi- Jora, A.

Batem. DENDROBIUM hedyosmum. Bateman, mss. Denprosivum albo-viride. Parish in lit. Although the vast majority of the species of the great Indian genus Dendrobium are entirely scentless, a few, e.g. D. macrophyl- lum, send forth disagreeable odours, while a still smaller number, among which may be classed the subject of the accompanying Plate, yield the most grateful perfumes. The fragrance of D. hedyosmum might almost be mistaken for Wallflower. Our plant was received from Moulmein two years ago by Messrs. Hugh Low and Co., of the Clapton Nursery, under the name of D. albo-viride, which had been provisionally given by its discoverer, Mr. Parish. And indeed when the flowers of a Specimen at Knypersley, from whence the figure is taken, first opened, they were unmistakably of a pale greenish-white and so far justified Mr. Parish’s specific name; but in the course of a few days these tints disappeared, the sepals and petals began to shine like polished ivory, while the disk of the lip glowed with a rich orange-yellow, thus entirely changing the appearance and character of the blossoms, and rendering the name of albo-viride no longer appropriate. Under these circumstances, I have ven- tured to substitute the name of edyosmum, in allusion to the delicious perfume of the flowers, a change which I cannot doubt will be approved by Mr. Parish himself. JUNE Ist, 1865, D. hedyosmum flowers in the spring, and its blossoms, after undergoing the change described above, continue in beauty for many weeks. It requires no particular treatment. Botanically, it is allied, though not very closely, to the plant already figured in this work (supra, Tab. 5454) under the name of D. margi- natum, respecting which I fell into an error that I am glad to take this opportunity of correcting. As the circumstances that led to the mistake were somewhat peculiar, I may perhaps be allowed to relate them; they were as follows:—Messrs. Low had received, in 1863, from Mr. Parish several new Dendrodia, among which was one that came to them under the name of D. xanthophlebium, and on which several flowers were speedily produced. When collating these by the aid of Dr. Lindley’s admirable paper (in the Linnean Transactions) on the Orchid- ology of India, I passed over altogether the species ranged under his “nigro-hirsute” section, because not a trace of black or any other hair was to be found on the smooth slender stems of our plant. Then, as I altogether failed to find it among the other sections of the genus, I naturally concluded that it must be new, and gave it accordingly the name of D. marginatum, in allusion to the white edges of its lip. When, however, after the lapse of a few months the fresh growth commenced, I found to my surprise that the young stems were abundantly clothed with black hairs, a circumstance that led me to turn once more to Dr. Lindley’s paper, and here, in the “ nigro-hirsute ”’ section that I had previously passed by, I instantly recognized the plant under its true designation of D. xanthophlebium. The latter name must therefore be restored, and my name of D. margi- natum cancelled. Dzscr. Sfems erect, clustered together, about a span long, when young clothed with small black hairs, which speedily fall off. Leaves narrow, short, and leathery, unequally emarginate at their points.

The plant from which our Plate was taken was flowered by Messrs. Backhouse, of York, whose collection of herbaceous plants is ce- lebrated for its beauty, variety, and high condition. The plant is a native of Hungary. ee The genus Heyatica, first indicated by Dillenius, has been accepted by some succeeding botanists and rejected by others, the former preponderating. Latterly, however, the discovery i Kashmir of a species of Anemone (A. Falconert, Thoms. in Hook. Ic. Plant. t. 899) closely resembling the H. friloba in habit and all other essential characters, except the position of the three JUNE 1st, 1865. involucral leaves, which afford the main distinctive character of Hepatica, invalidates the latter genus altogether.

At Tab. 2250 of the ‘ Botanical Magazine’ has been given a figure of the noble Foureroya gigantea of Ventenat, and at our Tab. 5163 another species of Fowrcroya, F. flavo-viridis, Hook. ; both of these, however, are stemless plants. We have now the great satisfaction of representing a far more striking species even than the F. gigantea, namely, the F. dongeva of Karwinski and Zucearini, which flowered in the conservatory of the Regent's Park Royal Botanic Garden, in the summer of last year, under the skilful management of Mr. Robinson,—for the first time, I have every reason to suppose, in Europe. The species was first made known to science by Baron Karwinski, distinguished by his botanical travels in Mexico, and it was figured and described by him and Zuccarini in the volume of the ‘Nova Acta’ above JULY Ist, 1865. quoted. It is this, too, that is so admirably illustrated by Mr. Bateman by an interesting vignette-landscape in his splendid ‘ Or- chidaceze of Mexico and Guatemala’ (under t. 17), with the quo- tation :— 7 **Unde nil majus generatur ipso, Nec viget quidquam simile, aut secundum ;” and with the further remark :—‘‘The stately plant here repre- sented is Fourcroya longeva, one of the most marvellous pro- ductions of the vegetable world. It belongs to the family of Amaryllidacee, and has the habit of a gigantic Yucca, its stem being frequently fifty feet high, and its flower-spike forty more! It was originally discovered on Mount Tanga, in Oaxaca, at an elevation of ten thousand feet above the level of the sea. Mr. Skinner has also met with it on the high mountain-ridges in the interior of Guatemala. Plants of the species exist in our nur- series, but, contrary to expectation, it seems to suffer severely from the cold and changes of our climate.” With us and in the Regent’s Park Garden, the temperature of a common greenhouse is sufficient for it; but the largest of our plants in cultivation are of course but pigmies in comparison with the height on its native mountains. At the time our drawing was made the specimen was past perfection (it has died after flowering), and we have thought it best to take our representa- tion of the entire plants (on the extremely reduced scale) from Karwinski and Zuccarini’s figures of the native plants. The flowers and analysis are from the recent specimen kindly com- municated by Mr. Sowerby. Descr. The plant which produced the flowers here represented was about fifteen feet high, including the flowering panicle, but we learn from travellers in Mexico and Guatemala that the stem alone there attains a height of forty and fifty feet, perfectly erect, straight, cylindrical, scarred transversely, terminated with a mag- nificent crown of Jeaves two to three fect long, coriaceo-carnose, from a very broad base, narrow, ensiform, very acuminate, with more the habit of those of some Yucea than of Fourcroya or Agave ; the surface above is quite smooth, beneath it is finely striated, and the strie and margin are rough with minute cal- lose sharp points. These /eaves are densely crowded, upper ones suberect, the lower ones are closely reflexed upon the stem. Scape terminal, for its whole length (said sometimes to equal forty feet!) forming a pyramidal much-branched panicle. Flowers bracteated at the base. Bracteas small, ovate, acuminate, about the length of the very short pedicel. Tube of the perianth (in- ferior ovary) three-quarters of an inch long, subcylindrical, glan- dulose-pubescent ; the Zimd spreading, two to two and a half inches across, white with a greenish tinge, yellow-green exter- nally, pubescent towards the base. Stamens six, large, erect. Filaments subulate, singularly strumose above the thickened base. Anthers sagittate, orange. Style below the middle, with three globose, large, erect ¢wbercles, which alternate with each pair of stamens. Ovary three-celled, obscurely three- or six-furrowed. Fig. 1.

The place that is occupied by Ceres senilis among succulents may be claimed for Dendrobium senile among Orchids, white hairs, which are inevitably represented as black in the Plate, being profusely scattered over its stems and leaves. These, joined to the long-lasting yellow blossoms, render the species at once a singular and attractive plant. It blossomed at Knypers- ley in April last, and from the flowers then produced, compared _ with the wild specimens kindly lent by Messrs. H. Low and Co., the accompanying figure was prepared. It seems to be rather a delicate species, and should be placed in a shallow pot or on a block of wood, and suspended near the glass.

The Cape genus Drimia of Jacquin, like many other Aspho- deleous genera, has its characters very vaguely expressed, and Professor Kunth remarks of it : “ Zachenaliam cum Scilla jungit, huic ob semina affinior ;” yet this latter author has separated his new genus Jdothea from it, and it is difficult to say to which of the two our present species should be referred. It 1s quite dif- ferent from any in either genus, and remarkable for its great size, large and copious green flowers, and the great length of the bracts, much exceeding the flowers before their expansion. It is a native of Natal, and we owe the possession of it to our valued friend John Sanderson, Esq., of D’Urban. It is certainly the finest of all the Drimias. : _Descr.

Hugh Low and Co., of Clapton, who being unable to distinguish it in habit from the old Phalenopsis eques- tris (P. rosea), disposed of several plants of it to their customers under that name. Several of these flowered simultaneously this spring, and no fewer than four of them were exhibited at the same time at one of the Tuesday meetings of the Royal Horti- cultural Society at South Kensington. These came from the collections of Mr. Day, Mr. Marshall, Dr. Patteson, and Messrs. Low, it has also appeared in that of Mr. Wentworth Buller. It appears to be of the very easiest cultivation, but requires a good heat. a Professor Reichenbach, in his very interesting description of the plant (published in the ‘Gardeners’ Chronicle’), mentions the circumstance of its having been first flowered by M. Liidde- mann of Paris (formerly at the head of M. Pescatore's cele- brated establishment), to whom the species was dedicated. Professor Reichenbach also observes that he has seen two varie- ties of this beautiful plant: one of them with the bars on the JULY Ist, 1865. petals and sepals altogether cinnamon-colour and to which he gives the name of “ ochracea ;’* the other (as in the case of the specimen represented) with the lower bars of a fine amethyst tint which he calls “delicata.” Our drawing was taken from a spe- cimen exhibited by Mr. Day.

Veitch, of the King’s Road Nursery, Chelsea, in May of the present year, as a native of Madagascar,— incorrectly, perhaps, so labelled, for we know of no true species of Bertolonia having been detected in Madagas- car, but we have beautiful samples identical with this in our her- barium, collected at St. Sebastian, Brazil, by the late Mr. Fox (n. 89), and again from the Province of St. Paul, South Brazil, collected by Mr. Weir, in 1861-2 (n. 40). It appears to be quite undescribed, and is, so far as we know, peculiar to Brazil. Three species of the genus only are described by Naudin, AUGUST Isr, 1865. to which he adds seven others (“sed quedam incerte ”), includ- ing the B. maculata of Martius, which we had supposed to be identical with our B. maculata, given at Tab. 4551 of this Ma- gazine. ae Re Descr.

Further, that Mr. Reid, not Mr. Robinson, had the charge of the conservatory in which the flowering of the plant was so successfully accomplished. We learn, too, that no seeds were produced, but a large crop of leaf-buds or gemme from the branches of the panicle, several plants of which were kindly . sent to Kew. 5525.

Costaricana, besides the rich scarlet colour of the flowers, the stem, pedicels, and calyx are purple, the leaves are auriculato-cordate at the base, rather strongly serrated at the margin, and the gynophore of the ovary is very short and globose. Our living plant of aurata produced smaller flowers, and those not full yellow, but pale sulphur-coloured. Descr. Stem a foot or a foot and a half high, square, green, slightly pubescent, as is the whole of the plant, the flowers most so. Leaves opposite, three to four inches long, petiolate, somewhat AUGUST Isr, 1865. deflexed, ovate, bluntly acuminate at the apex, the base rather deeply auriculato-cordate, the /odes approximate, the margin en- tire, or obscurely and remotely denticulate. Veins few, remote, oblique, mostly simple. Petioles one to two inches long. Laceme terminal, solitary, straight, bearing numerous flowers on short pedicels, bracteated at tne base; dracteas small, linear, recurved. The raceme, when the flowers are all developed, attain a height of six to eight inches. Calya green, formed as in the genus. Corolla one and a half to two inches long, erect, deep fulvous or (in our var.) sulphur-coloured ; with a deeper yellow tinge about the faux ; fube narrow, elongate, infundibuliform ; upper ip helmet- shaped, three-lobed, covering the faux, /ower lip patent, broad ovate, emarginate. Stamens and style included. Ovary small, deeply four-lobed, situated at the apex of a large, fleshy, elon- gated, curved gynophore, tapering upwards. Sty/e filiform. Fig. 1. Flower,— magnified. 2.

This we have referred to Psammisia, rather than to Thibaudia, on account of its near affinity with Psammisia pendulifiora, Kl. (Thibaudia, De Cand.), given at our Tab. 5204. Indeed, we do not clearly see the reason for the formation of the genus Psam- misia ; but if the genera of this Vaccineous group of Ericacee are hard to determine, much more is it hard to determine the limits of the species, especially since most of them are described from dried specimens, when the flowers become much changed AUGUST IsT, 1865. by desiccation. Hence the importance of securing figures from living plants. Hence it will be seen that while in P. penduliflora the whole flower is more or less furfuraceo-scabrous and the co- rolla short, in our P. /ongicolla the flower is quite smooth (/ev7s) and the corolla elongated and suddenly contracted into a distinct neck between the swollen portion of the tube and the limb. In both the corolla is two-coloured, red for the greater part of the length, then suddenly green. Dusor. A straggling shrub of a few feet in length, with glossy coriaceous Jeaves, three or four inches and more in length, shortly petioled, much acuminated, entire, three- to five-veined, with veins connected by fine transverse veinlets (as in many Melastomacee). Racemes short, axillary, glomerate, drooping, partially bracteo- lated. Pedicels fleshy, thickened upwards, so as to be almost clavate. Ovary jointed upon the pedicel, globose, smooth, having two ovate dracts at the base; free portion of the calyx cup- shaped, with five short, erect, acute /obes. Corolla bottle-shaped, the wide and longest portion of the tube scarlet, the column or neck much contracted, and green as are the five subtriangular and somewhat spreading /odes of the diméd. Stamens large, but quite included. Filaments short. Anthers tapering into two erect, tubular forns, opening by a longitudinal pore or slit. Fig. 1. Flower with a pair of bracts at the base. 2.

An interesting account—for which we are indebted to Pro- fessor Reichenbach—of this remarkable Phalenopsis appeared in the ‘Gardeners’ Chronicle,’ the first week of last June. From this we learn that the species is a native of the province of Pa- lembang, in Sumatra, where it was originally discovered by Kort- hals, more than a quarter of acentury ago. By him it would seem to have been sent to the Botanic Garden at Leyden, where it flowered about the year 1856, and where an imperfect figure— subsequently published in the ‘ Annales’ as P. zebrina—was pre- pared. But although long since introduced to Continental collec- tions, the species was never seen in this country before the spring of the present year, when it flowered beautifully in the collec- tion of Mr. Day, who exhibited at South Kensington the speci- men from which Mr. Fitch’s drawing was taken. oe Professor Reichenbach remarks that the azher-lid is fringed : after the manner of Zrichopilia, and that the apex of the lp is AUGUST Ist, 1865. furnished with “hairs quitg as dense as in a good hat-brush.” It is as easily managed as any of its congeners. Descr. Leaves pointed, about six inches long. Flower-spike — about the length of the leaves, five- to ten- flowered. Sepals oblong, pointed, not carinate, an inch or more long. Pefa/s more cu- neate than the sepals, which they otherwise resemble, both in form and colour, the latter being yellowish-white, barred with — broad streaks of rich reddish-brown. zp short, unguicuate, three-lobed, the lateral portions meeting in front and stretching backwards, in which direction they end in a sort of curved tooth; the middle portion, which is pressed closely together at the base, is fleshy throughout, and very hairy in front, of an oblong or slightly panduriform shape, carinate along its centre line, and provided with two slender, sharp, upright processes at the point of its junction with the lateral lobes. In colour the hp is white, with orange spots on its side partitions, and four lines of violet (or in some varieties lilac) streaks along its central lobe. | Column white, semiterete, rather fiddle-shaped, with its anther-lid fringed.—J.

This extremely handsome state of the well-known Primula cortusoides has been recently imported into English gardens from Japan, and our figure is taken from a living plant entrusted to us for the purpose, by Messrs. Veitch, in May of the present year. One has but to compare our present figure with the figures quoted above, or with native specimens from the Russian domi- nions in our herbaria, to justify the preference that must be given to this variety, on account of the size of the foliage and umbels and flowers, and the deep, almost purple colour of the latter. Thunberg, indeed, in his ‘ Flora Japonica,’ says of the species, “Crescit hine inde in insula Nipon ;” but he adds, “ seepe In hortis culta;” and Dr. Asa Gray, in his ‘Japan Collections of AUGUST Ist, 1865. Williams and Morrow,’ gives it as an inhabitant of Simoda: but as we have never received it in any of the numerous collections of specimens we have received from Japan, is it not likely, since the Japanese are great gardeners, they may have imported it from Siberia, as they appear to have done the Primula Sinensis? At any rate it is a great acquisition to European gardens. Descr. Root a rather slender horizontal or ascending rhizome. Leaves all radical, downy, as is all the herbaceous part of the plant, ovate or oblong-ovate, cordate, dark-green above, paler beneath, wrinkled, many-lobed at the margin, the /odes acute, toothed. Petioles terete, three to four inches long, tufted with scales or bracts at their base. Scape longer than the foliage, bearing an wmbel four to five inches in diameter; the pedicels with an émvolucre of several-whorled linear-lanceolate scales or bracteoles at their bases. Calyx rather large, of five deep, ovato- lanceolate, striated Jobes. Corolla hypocrateriform ; the /imé an inch and a half broad, plane, deep purple-lilac, with a white star at the faux ; odes of the limd deeply obcordate. Stamens quite included.

It is a native of Ceylon, and was sent to Kew, in 1862, from the Botanic Garden at Peradenia, by Mr. Thwaites. Placed at the cooler end of the East Indian house, it flowered finely in June of the present year under the zealous management of Mr. Smith.

As in the case of the Phalenopsis figured at Tab. 5527, the honour of having been the first to introduce and to flower the subject of the opposite Plate rests with the Continental Orchid- growers. And it is one of which they may well be proud, for no species of the lovely genus to which it belongs—no, not even P. amabilis itself—can at all be compared with it in beauty. In dedicating it under these circumstances to his distinguished countryman Consul Schiller, of Hamburg, Professor Reichenbach » paid a well-merited compliment to one whose collection of Orchids has long been renowned and still maintains its celebrity. _ There are many varieties, which differ from each other in the marbling of the leaves, and in the size and tinting of the ee soms. Those which first appeared among us scarcely gave ee idea of the effect the plant is capable of producing when the - ; kinds have attained their proper vigour. Mr. Williams, of Hol- loway, mentions his having imported a plant on which was a na- tive flower-stem that had borne a hundred blossoms, and I have little doubt that—as the plants in our stoves improve every yoo —at least an equal display will ere long be made in this country. AUGUST IsT, 1865. As the plant is found at a higher level in the Philippines than P. amabilis, it need not be kept quite so warm, but under almost any circumstances it grows well and blooms freely in the winter and spring. The figure was taken from a glorious specimen that flowered in the nursery of Mr. Veitch in May last. In the size of its blossoms and the delicacy of its tints, this variety eclipses all that have as yet shown themselves. Descr. Leaves from six to eighteen inches long, oblong and coming to a blunt point, beautifully marbled on the upper side with irregular whitish streaks on a dark-green ground, the un- der side being purple. Peduncle one to three feet long, bent downwards, branched, many-(10-100-)flowered, all the flowers being open at the same time. Sepals an inch or more long, the dorsal one obovate and rather sharp-pointed, the lateral ones ovate and more acute. Petuls of a rhomboid form, much wider than the sepals, and, like them, of a rich rosy-lilac colour, be- coming fainter or almost white at the edges. Lip three-lobed, the lateral lobes white, oblong, rounded, and stretching back- wards, with a four-cornered yellow callosity at their base; the middle lobe rosy-lilac, oval, and split at the summit into two slender portions, that diverge from each other and are gracefully set Column blue, clavate, prolonged, and free at the base.

This showy species of Lankesteria was sent to us by Dr. Moore, of Glasnevin Gardens, and was raised from seed sent from West Africa by Mr. Milne.

The true Z. elegans has broader bracts, much shorter and somewhat broader calyx-segments, and a glabrous corolla-tube. There are specimens of it at Kew, collected by Mann. Though the flowers are represented in the Beauvois plate as rose-coloured, it is not unlikely that they are orange, like those of Z.

The SEPTEMBER Ist, 1865. drawing, which was made in June, shows the earliest stage of the inflorescence, when a single involucre terminates each flower- ing branchlet. The plant is still in flower in the Cactus-house, and now each branchlet bears an umbel of three rays. The plant is especially remarkable for the curious successive produc- tions of the staminate flowers, of which one or two appear the first day and wither away, to be succeeded next day by about four more; when these have withered, several more appear in succession on the third and fourth days.

CaLaTHEA Veitchiana. J. Veitch, mss. Of the tribe of the Arrowroots (Marantez), so remarkable for the beauty of their ample foliage, there are few species, if any, which can take higher rank in ornamental culture than the subject of this Plate, one of two apparently undescribed species recently forwarded to us in flower by Messrs. Veitch, and ob- tained by their collector, Mr. Pearce, in Western Tropical South America. C. Veitchiana, with its sceptre-like scape and dense flower-head, the bracts imbricated all round, belongs to the same section of the genus (Pseudophrynium, Kérnicke) as the old Calathea (for- merly Maranta) zebrina. It differs from any of its congeners known to us in having several of the rather large upper bracts empty as in Hucomis, and from its nearest allies in the form and colour of the perianth, of which unfortunately we do not possess the material to enable us to give a detailed description of the inner segments and adherent staminodia. This species is named by Mr. James Veitch in remembrance of his late father, “ with whom it was a great favourite.” Descr. The large petiolate radical /eaves are more or less ovate-elliptical, scarcely or but shortly pointed, broad and rounded at the base, glabrous on both sides, marked above on each side OCTOBER Ist, 1865, of the midrib with large, crescent-shaped, connected, dark-green blotches, having their concave sides towards the midrib, which the cusps nearly or quite reach. ‘Toward the margin the leaf is similarly deeply-coloured ; petioles very slightly hairy. Scape tolerably firm, about as thick as a goose-quill, cylindrical and minutely hairy, shorter than the leaves. Spike two to three inches long and about two inches in diameter; éracts rather closely imbricated in the lower part of the spike with more or less spreading tips, the upper part on the outside thinly clothed with long loosely appressed hairs, the upper bracts empty and spreading, coloured reddish beneath towards the apices. Flowers small, in fascicles of three to six in the axils of the bracts, subtended by oblong or linear-oblong membranous dracteoles. — Calyx-limé of three equal linear segments, shorter than the tube of the corolla, but several times longer than the ovary.

It is not a little remarkable that of the beautiful genus Dian- thus not a single species has been figured in the ‘ Botanical Ma- gazine’ since the year 1827. Nor does our annexed Plate re- present either a new species or even a species figured for the first time in this series. There can be no doubt of the specific identity of the gay plant on the opposite page, bearing flowers four inches in diameter, with the modest little Indian Pink figured in the first volume of the ‘ Botanical Magazine’ (Tab. 25). The differences between these extreme forms, though perhaps even more marked, are altogether analogous to those which obtain between the figures, dated respectively 1504 (Tab. 758) and 1854 (Tab. 4816) of Kniphofia Uvaria. They are differences which, we have evidence to show, are due to the continued in- fluence of rich soil or to the skill of cultivators through some other medium. The favourite Indian Pink appears, like the Zinnia, after long cultivation in Europe and Japan, to have broken out into several very striking varieties, well worthy of the » attention of our florists. Of the more remarkable forms several have been carefully described and figured in Regel’s ‘ Garten- flora’ (Tabb. 216, 240; see also Fi. des Serres, 1150 and 1288), and it is to the form which Dr. Regel distinguishes as D. Chinensis-laciniatus, that the plant here figured by Mr. Fitch belongs. The tendency to variation is by no means confined to OCTOBER Ist, 1865, the petals, which may be either’simply dentate or very deepl laciniate. The bracts surrounding the base of the tubular calyx, the relative length of which organs is so often employed as a tributary specific character in the genus, vary also very much, and in a few flowers now before us, we find them varying from ovate-cuspidate and but half the length (or less) of the calyx, to linear-acuminate equalling or sometimes considerably exceeding the calyx. The form and direction of the leaves is also variable. The case is one which it might be advantageous to study carefully with a view to the general principles which govern variation in plants. Descr. Stems decumbent or ascending, six inches to one foot _ or more in height, usually branching, glaucous. eaves linear to linear-lanceolate, acuminate, entire, glabrous and glaucous, or very minutely scabrid-puberulous, denticulate-ciliolate. Flowers very large, terminal, solitary, from white or pink to crimson, or variously blotched. Bracts ovate-cuspidate, much shorter than the calyx, to linear-acuminate, exceeding it in length. Lamina of the petals cuneate, deeply fimbriate. —Szamens and style vary- ing in relative length in different plants (owing to a dimorphic condition carried to an extreme in some unisexual species of the same Order).

This very remarkable Dendrode is a native of North Australia, where it was recently discovered, at no great distance from the coast, by Mr. J. G. Veitch, who sent it to his father’s establish- ment at Chelsea in the spring of the present year. ‘The plants of this and of another species figured in a subsequent Plate (Tab. 5540), arrived in such excellent condition that they have already flowered freely both in the Exotic Nursery and in the collection of Lord Egerton of Tatton. The species being quite new, I gladly availed myself of the opportunity of dedicating it to the latter nobleman, whose ee of hee is =e ingly rich and admirably grown. e species has a pleasan tell and continues in ae for two months. Like D. bi- gibbum, from the same country, it is very easily cultivated. The specific character is from the accurate pen of Professor Reichenbach, to whom, as well as to myself, flowering specimens were sent. OCTOBER Ist, 1865. Descr.

SraCHYTARPHETA Jicolor ; suffruticosa, foliis ovatis v. ovato-lanceolatis acutis serratis basi in petiolum brevem angustatis glabris, spicis sublaxifloris, bracteis subulatis acutis, corolla tubuloso-infundibuliformi calyce*duplo lon- giore, tubo infra medium abrupte curvato atque angustato, limbo breviter recurvo, germine basi gibboso. Though less effective than S. aristata (Bot. Mag. Tab. 4211), this interesting species has the advantage of many of its weed- like congeners in the comparatively great length of its corolla, which is moreover of an unusual colour. On emerging from the bud of a deep purple, it soon acquires a peculiar greenish-blue, the throat remaining white. It is further remarkable in the form of the corolla, which is funnel-shaped, with a very short spreading limb, and not hypocrateriform or salver-shaped, as is usual in the genus. The specimen from which our figure was drawn developed its flowers on the passage home from Bahia, whence it was forwarded to us by our excellent correspondent C. H. Williams, Esq.; and it is just possible the unusual colour of its flowers may have something to do with the circum- stances under which they were produced. Although there are thirty-five species of Stachytarpheta described from Brazil, our friend M. Bocquillon, who has made the Verbenacee his special study, and who happens to be by us as we prepare this for press, is unable to refer this plant to any of them, so that we have no alternative but to publish it as new.

Reg. 1732), which is a mere variety of this species, re- marks, that it may perhaps be considered the finest of the ex- tensive genus to which it belongs. Few things can be more effective than a well-disposed patch of this plant. It is an old inhabitant of gardens in the south-west of England, and well known in many out-of-the-way places, but by no means so generally as it deserves. It is with a view to draw attention to it and to its congeners, which have been too much neglected of late years, that we have had figured this species from a plant grown in the Scilly Islands, obligingly sent to us by A. Smith, Hsq., M.P. It is a native of the Cape of Good Hope,—the head-quarters of the Fig Marigolds,—growing, according to Dr. OCTOBER Ist, 1865. Sonder (‘Flora Capensis,’ v. 2. p. 412, whence we have obtained the above synonymy), on the sandy flats near Cape Town, etc. M. rubrocinctum differs from our variety solely in the trivial character of a frequent red line along the leaf-margins. The fruit is said to be eatable. Descr. Stem two to four feet, procumbent, pointed, the young shoots compressed and angular. eaves two to three inches long, about three-quarters of an inch in thickness a little above the middle, triquetrous, pointed, and more or less narrowed to the base, where the opposite leaves are shortly connate ; the keel, and sometimes the upper edges of the leaf, are either ser- rulate or entire, with or without a red line. Peduncle two- edged, with a pair of connate dracts. Stamens tour to five inches in diameter ; petals purple, linear, emarginate. Anthers dark-purple. Stigmas twelve to fourteen, pale-yellow. Fig. 1.

Asin the case of the species figured in a preceding Plate (Tab. 5537), our knowledge of this very interesting addition to the vast genus Dendrobium is due to the researches of Mr. John G. Veitch on the northern coasts of the great Australian continent. From hence it was sent to the Exotic Nursery in the King’s Road, where it flowered freely along with D. Tattonitanum im August last. Specimens having been communicated to Profes- sor Reichenbach, he very properly named the species in honour of its discoverer, being compelled for that purpose to avail him- self of his Christian name, inasmuch as the surname of the family had been already (in the Dendrobium Veitchianum of Lindley) pressed into a similar service. Though not so gay as D. Zattonianum, it is well worth grow- ing, and is apparently of the easiest cultivation in an ordinary orchid-house. The flowers, which are remarkable for their twisted sepals and petals, exhale a pleasant odour of honey.—/. B. Fig. 1. Lip and column, 2. Pollen-masses :—magnified.

This is by far the finest species of a genus that otherwise com- prehends none but insignificant plants. It must also be regarded as the most extensively dispersed, if Professor Reichenbach’s supposition, that it is a mere variety of J. wéricularioides should - prove to be well founded, the latter species being diffused over nearly the whole continent of South America. The speci- men figured was taken from among a multitude imported from Brazil by Messrs. Hugh Low and Co., of Clapton, and which formed one of the most attractive features of their orchid-houses during the months of October and November last year. There Were innumerable varieties, some almost pure white, others white and yellow, and others again—like the subject of the Plate— with a lovely purple spot on the lip. The flowers last for a con- _ siderable time, and are very freely produced ; indeed in order to | preserve the plants in health it is sometimes necessary to destroy the flower-spikes, which, as in the case of the species of Phale- NOVEMBER Ist, 1865. nopsis, are often out of all proportion to the number and strength of the leaves. ‘The species succeeds under the same treatment as Burlingtonias or the more delicate kinds of Oncidiwm, and should be placed either on a block of wood, or, what is far better, on one of those earthenware imitations of a block of wood to which the name of ‘ branch-orchid pots ” is now applied.

It is a very graceful species, and its habit and prettily blotched leaves cannot fail to render it a valuable addi- tion to our variegated stove plants.

A South African plant, originally described by Thunberg, be- longing to the same remarkable category as the Adenium obesum figured recently in this journal (Tab. 5418), and the two gouty- stemmed Vines, VY. Bainesii and V. macropus (Tabb. 5472, 5479). The exceptional habit of these plants in the families to which NOVEMBER Isr, 1865. they respectively belong, affords an interesting problem for the consideration of those who incline to the derivative origin of species, and may be supposed to illustrate one kind of useful character, “‘ selected,” and thus apparently. moulded, by the exter- nal conditions to which they have been exposed through a long period of time. There can be no doubt that our plant is the same as P. tuberosum, Lindl., the figure of which we quote above. At the time of publication of that species the true P. succulentum of Thunberg was not certainly known. Indeed M. A. De Can- dolle, in the ‘ Prodromus,’ retains the two as distinct. They have been reduced to one species by M. Planchon (MS. note in Herb. Hook.). The caudex of another species of the genus Pachypodium (P. bispinosum) is said to be edible. Our figure is from a speci- men flowered in the Royal Gardens, Kew, presented by W. W. Saunders, Esq., and sent home by Mr. Cooper from South Africa. Descr.

Notwithstanding the publication of an excellent engraving of this plant in the Report of the Botany of the American Survey, referred to above, it would appear to be hitherto undescribed. In habit it much resembles Aéronia mellifera, figured in this Magazine (Tab. 2879), differing in the form of the involucral leaves, and the size, colour, and lobing of the perianth. It is the finest species of the small genus to which it belongs, and may be regarded as a valuable addition to our garden flora. Geyer, who collected specimens on the “ loamy, sandy, firm banks of the Platte river, describes the flowers as “ porcelain-coloured, opening only at night and very fragrant.” It is to the sandhills — of this tributary of the Missouri and the eastern flank of the | Rocky Mountains, between 40° and 45° north latitude, that the species appears to be confined. We are indebted to Mr. Thompson, of Ipswich, for the specimen here figured, the first probably which has been flowered in England. Drscr.

A pretty and interesting plant, originally flowered some twenty years ago by the Messrs. Loddiges, when it was doubt- fully referred to Oncidium by our great English orchidist—now, alas, no more! Since then the plant has appeared in the collec- tion of Consul Schiller, when the examination of more perfect specimens satisfied Professor Reichenbach that it was a truly distinct form, to which he applied the generic name of Palum- bing. Tt was introduced from Mexico by Hartweg, while in the service of the London Horticultural Society, but was probably lost through having been kept too warm. In a moderate tem- perature it is easily grown, blooming during the summer months and lasting long in beauty. The figure was derived from a very fine specimen exhibited in June last at South Kensington by Mr. Day. It has also flowered in the Royal Gardens at Kew. Descr. A small plant with narrow compressed pseudobulbs, each bearing a single linear or slightly wedge-shaped leaf from six inches to a foot long.

For this superb plant we are indebted to James Bateman, Esq., a most successful cultivator of the genus, who flowered it in September of the present year, and at whose desire it bears the name of a lady who was an ardent admirer of the genus; of © its precise habitat we are uncertain, but believe it to be the moun- tains of Caraccas, the plants having been procured from Mr. Linden’s celebrated establishment at Brussels. It was sent under the name of 7! macrophylla, H. B. K., a plant which differs remarkably in the long pedicels of the flowers, and according to specimens so named by Bentham (and collected in Humboldt’s locality by Hartweg) in the very coriaceous leaves. The most decided characters by which the 7. Jessice differs from its nearest allies are the very slender ultimate branches, singularly mem- branous texture of the very large leaves, large flowers, and short pedicels. It resembles a good deal a species in the Hookerian Herbarium collected by Professor Jameson on Pichincha, at an altitude of S000 feet, and may be the same, but the leaves and flowers both appear to be very much larger. Descr. A glabrous shrub, with pendulous branches. Leaves a span to ten inches long, shortly petioled, ovate or ovate-lanceo- late, rounded at the base, narrowed into a long acuminate apex, quite entire, membranous, with five more prominent nerves and — numerous reticulating lesser ones.

The true Trichopilias seem to be almost exclusively confined to that remarkable isthmus, so rich in Orchids, which connect the northern and southern portions of the vast American con- tinent. They are especially numerous on the mountain ranges of Veraguas, where, -as its name implies, the present species Was found on the slopes of the snow-capped Turialva.* — Pro- fessor Reichenbach, by whom it was first described, thus speaks of the plant in the ‘Gardeners’ Chronicle’ (Aug. 19, 1865, p. 770), “a species in the way 7: albida, Wendl. fil.; 7. o160- phylax, Rehb. fil.; and 7. maculata, Rehb. fil. ; none of which can boast much beauty. ‘I'he erect fimbriate membrane surround- ing the anther reminds one of an old-fashioned, stiff, erect, lady’s collar. The flower is yellowish-white, the lip deeper yellow. It was discovered by Mr. Wendland, the son (or rather the grand- son, since he is already the third of the Wendlands), on the voleano Turialva, in Central America. Later it was also ob- served by a traveller named Sell.” I would add that in its colouring and general appearance it is not unlike the 7. picta of Lemaire. : The species has flowered in several collections during the past * The name of the mountain (literally “ white tower ”’) was given to it by the Spaniards to describe its remarkable appearance from the sea. DECEMBER Ist, 1865. summer, and, judging from the specimens I have examined, seems to vary considerably in the size and tinting of its blossoms. Mr. Fitch’s drawing was taken from a plant exhibited in July last at South Kensington by Mr. Williams, of the Paradise Nursery. - Like the rest of the genus it is very easily managed, provided it be not kept too warm. The Trichopilias, however, can scarcely be reckoned amongst “cool” Orchids in the extreme sense of the term, requiring as they do, a temperature considerably higher than would suffice for many of the most popular Odontoglossa. —J.
