TO SIR JOHN KIRK, G.C.MG. FERS, PLS, &., &e. LATE H.M. AGENT AND CONSUL-GENERAL AT ZANZIBAR. My pear Kirk, For many years past the volumes of the Boranican Maaazrne have annually been enriched by figures of new, rare, and interesting plants, introduced by you from Zanzibar into the Royal Gardens of Kew. These represent, and but feebly, a mere fraction of the great services which you have rendered,—to Science by extending our knowledge of the Natural History (especially the Botany) and the Geography of Eastern Tropical Africa, and to mankind by the development of new industries (such as the Indiarubber trade) in that country. That these services should have been performed under the pressure of arduous political duties, and in a trying climate, has always appeared surprising to me; and I hope that you will accept the dedication of the volume of the BoranicaL MAGazinE which contains the Indiarubber plant (sent by yourself), as a token of the value I attach to your contribu- tions, and of my admiration of your zeal and enlightenment as a public officer.

This very striking plant was introduced about the year 1823 from India,where it was discovered by Wallich in Nepal, in the Valley of Katmandoo. It has subsequently been gathered in the Sikkim Himalaya by myself at elevations of 4000 to 7000 feet, and in the Khasia Mountains at about the same altitude. Dr. Wallich, in a valuable monograph of the genus quoted above, justly commends it to cultivators in the following terms :—*‘ This is the queen of the genus, if not of the whole order, both as regards the general aspect, the stature and the foliage, and the exquisite elegance as well as fragrance of the ample inflorescence. While I write this, several large patches of the typical form are in full bloom at the Horticultural Society’s Garden at Chiswick, thriving luxuriantly in a temperate glass-house, without any extraordinary supply of water; and last year I saw it in equal perfection. What can be the reason that a plant so charming and desirable as this is not more frequently seen in the stoves of the great and wealthy ? Surely there exists not an Orchidea which exceeds it in any respect, especially in facility of cultivation.”” It com- memorates in its specific name one of Dr. Wallich’s most gan. Ist, 1887. ° zealous contributors of living plants, of whom he says :-— “During a number of years in which the Hon. Edward Gardner (son of the late distinguished Admiral Lord Gardner) lived in Nipal, as the Hon. Hast India Company’s Resident at the Court of Katmandu, he contributed greatly to the riches of the Botanic Garden at Calcutta, and through it, to the gardens and herbariums of England. It “was through his local influence, and afterwards also of the late Mr. Robert Stuart’s, the officiating Resident, that I was permitted to send permanent collecting parties into that country, where they enjoyed his unceasing support and encouragement; and afterwards to visit ‘it myself during a whole year, which I spent under his friendly and hospitable roof. Would that the cause of Natural History could boast many such Meecenases in India and everywhere else !’ _ Though a well-marked species, H. Gardnerianum is subject to a good deal of variation in the form and size of the lip, from orange to lemon colour, and almost white with a pinkish centre. The specimen here figured flowered in the Palm House of the Royal Gardens in August, 1885, and fruited in the following February. In the Temperate Phe: it also does well —J. D.

Amasonra calycina ; foliis petiolatis oblongo-lanceolatis acuminatis grosse irregu- lariter serratis dentatisve basi in petiolum angustatis glaberrimis, racemis gracilibus elongatis nutantibus villoso-tomentosis foliaceo-bracteatis, bracteis petiolatis elongato-lanceolatis acuminatis rubris, floribus breviter pedicellatis, calycibus amplis rubris 5-partitis, segmentis 3-pollicaribus e basi lata lanceolatis tenuiter acuminatis, coroll~@ extus laxe pilose flave tubo calyce ter longiore subcylindraceo, lobis brevibus late ovatis obtusis recurvis, filamentis exsertis basi pilosis, stylo piloso, bacca globosa calyce rubro suffulta. A. punicea, Hort. non Vahl. The genus Amasonia contains ten or a dozen imperfectly characterized species of South American herbaceous or suffruticose plants, chiefly natives of Brazil and Guiana, though some extend to the Andean provinces of Peru, Bolivia, and Equador. That here figured approaches nearest to an Amazonian one collected by Spruce (No. 2030) on the Rio Negro, and which is referred by Bentham to a variety of A. angustifolia, Mart., but that differs from A. calycina in having pubescent entire leaves, a much smaller calyx, and bracts that widen upwards; its calyx and fruit too are very much smaller. From A. punicea it differs in the very differently shaped bracts and large calyx. A. calycina was introduced by Messrs. Veitch from British Guiana, whence it was sent by their collector, Mr. D. Burke. Our drawing was made from a specimen pre- sented by that firm to the Royal Gardens in 1885, which flowered in Sept. 1886, and fruited, but did not ripen seed, in the following November. It is a truly splendid plant, and has the rare advantage of remaining in flower for two months at a time. Descr. A tall shrub or undershrub. Leaves six to twelve inches long, elliptic or oblong-lanceolate, acuminate, gan. Ist, 1887. coarsely irregularly toothed or sinuate, narrowed into a petiole one to two inches long, quite glabrous except the upper floral ones, which are often variegated with bright red. Racemes six to ten inches long, nodding, copiously leafy, softly tomentose with spreading red-purple hairs; bracts or floral leaves pubescent, faleately recurved, petioled, the lower often flowerless or with imperfect flowers ; in some racemes all are bright red, one to one and a half inch long and secund, in others they are all foliaceous and narrowly lanceolate, long-acuminate, two to three inches long, and green mottled with bright red, or scarlet tipped with green. Flowers shortly pedicelled, drooping, one and a half to two inches long. Calyw nearly an inch long, pubescent, bright red; tube short, subglobosely campanu- late ; segments lanceolate from a broad base, finely acumi- nate.

P. capitata, var. crispa, Hort. ‘ P. erosa belongs to a common type of Himalayan Primulas, that of which P. denticulata is the prevalent form, and P. capitata the rarer. In their usual states they | are distinguished as follows: P. denticulata by having sparingly mealy or glabrous finely toothed leaves, that are not fully developed till after flowering, and which are surrounded at their bases by fleshy. scales, formed by the arrested outer ‘leaves on the crown of the rootstock ; it bears a large or small depressed globose head, the flowers _of which are lilac or purple, and all open together. Plate 3959 of this work is an excellent representation of it, showing well the fleshy arrested leaves on the crown of the rootstock. The figure in the Botanical Register (1842, t. 47) is also characteristic, though the arrested leaves are concealed. __ P. erosa differs from denticulata in its much slenderer | habit, in always (except on young parts) wanting the meal — mn the leaves, which are developed at flowering time, are translucent with strongly erose and denticulate margins, AN. lst, 1887. and have a strongly reticulated surface, and the petioles are often red; the umbels are loose or dense-flowered, and the flowers in our garden specimens are of a far deeper purple than is usual in denticulata. P. capitata differs greatly in habit from both the above ; it is confined to the Eastern Himalaya, has finely denticulate leaves, often snow-white with meal beneath, but some-. times not so, a tall also mealy scape and globose densely crowded head of sessile flowers which open slowly, and the uppermost unexpanded ones are depressed and imbri- cate over one another like the tiles of a house. The corolla is of a very deep purple blue, the tube and calyx both short. Tab. 4550 of this work gives an excellent figure of the extreme form of capitata. Now, though these distinctions are so well marked in extreme forms, they all disappear in innumerable inter- mediate ones. As an instance I have figured on the same plate (at B.) with P. erosa, a leaf and head of a form of P. capitata, which happened to be flowering in the Royal Gardens at the same time with it. Comparing this with the figure at Tab. 4550, the difference will be seen to be very great; the leaves indeed are similar, but the head is far looser, the flowers three times as large; the calyx is nearly the same, but the corolla-tube is much longer and inflated above the middle. The herbarium shows many intermediates between this form and that figured at Tab. 4550; and in like manner there are many intermediate forms between P. denticulata and erosa. Lastly, some of these forms of denticulata appear to approach states of the Siberian and Kuropean P. altaica, Lehm., and P. farinosa, L. P. erosa is found throughout most parts of the Himalaya, but I did not observeit in Sikkim. Itis known in gardens as P. capitata, var. crispa. Both it and the P. capitata here figured were raised from seeds sent by Dr. King, of the Calcutta Botanical Gardens.—J. D. H. Fig. A.

Nympxa flava ; rhizomate oblongo v. cylindraceo, foliis ellipticis late, oblongis rotundatisve subtus rubris marginibus integerrimis v. subrepandis lobis ‘subacutis obtusisve, floribus flavis, sepalis oblongo-lanceolatis petalis concoloribus intimis sensim minoribus, filamentis exterioribus medio dilatatis antheris obtusis multo longioribus, intimis linearibus brevioribus, stigmatis radiis 8 brevibus incurvis obtusis inappendiculatis, N. flava, Leitner in Chapman Flora of the Southern United States Suppl. p- 604; W. Watson in “ The Garden,” vol. xxvii. (1885), p. 439 and 599. This is a very rare plant, having been comparatively recently made known to Botanists by the researches of Dr. Leitner in Florida, though it was much earlier recognized by a Naturalist; for, according to Chapman’s “ Flora,” it is figured in Andubon’s great work on the Ornithology of the United States, published upwards of half a century ago. As a species it is quite unlike any other, though belonging to the northern section Castalia, and not very far removed from the American JN. odorata, from which the colour of the flowers at once distinguishes it. N. flava is a very elegant plant; it was flowered in the Water Lily House of the Royal Gardens in July of this year. The Kew plants were received from Prof. Sargent, of Brooklin, Boston, in 1877, and again in 1880 from Mr. ‘Sturtevant. The plant flowered for the first time in the Water Lily House at Kew in July, 1882. Mr. Watson, in his excellent remarks on this species, notes especially the form of the elongated rootstock, which becomes covered with scale-like tubercles, and forms successive apical crowns of foliage and flowers subtended by a ring of roots, whilst the lateral tubercles develop stolons from which the plant is reproduced. Mr. Watson further remarks that it has JAN. Ist, 1887. been established in ponds and lakes in Kent, and there flowered freely for several years in succession. The figure of the rootstock here given is taken from Herbarium specimens collected in the St. John’s River by Mr. Curtiss. It has also been found in the Miami by Mr. Garber, and in a few other localities, all in Florida. Desor. ootstock cylindric or oblong, apparently not creeping. Peduncles and petioles dark green. Leaves two to six inches in diameter, orbicular elliptic or broadly oblong, green often blotched with dark red, margin entire or waved; basal lobes subacute or obtuse, parallel, with a narrow sinus. lowers four inches in diameter, pale yellow, opening at noom and remaining expanded till sunset. Sepals linear-oblong or oblong-lanceolate, subacute, rather darker yellow than the petals, with a faint rosy tinge externally towards the margin ; nerves very slender. Petals of the same form as the sepals, but rather paler, the inner shorter and broader. Stamens numerous, suberect ; filaments of the outer dilated in the middle, and much longer than _ the anther; of the outermost short, broad, concave, and petaloid ; of the innermost narrower and linear; anthers linear, connective hardly produced, tip rounded; cells parallel.

Gray in Proc. Amer, Acad. vol. xix. p. 4, and Synopt. Flora of NV. Amer. vol. i, pt. ii. p. 242. This is one of two species of the North American genus Silphium which Gray includes under the ‘* Compass Plants,”’ and of which the original, 8. laciniatum, L., was figured at Plate 6534 of this work. S. albiflorwm is not nearly so handsome a plant as S. laciniatum, being comparatively a dwarf, of robust rigid habit, with nearly white flowers. The cultivated specimens are much less scabrid, as might be expected, than the native, and have longer points to the involucral bracts, giving a squarrose look to the unopened heads; these latter, too, are much longer peduncled, and indeed Mr. Thompson sends a specimen in which the stem is terminated by a solitary long-peduncled flower- head. There is a further difference in the achenes; those of the native plant have the wings produced upwards into somewhat triangular teeth which are often adnate to a pair of subulate and more or less projecting rigid awns; in the garden plant the upward continuation of the wings are rounded at the tips, and there are no awns, in a young state at any rate. I am indebted for living specimens of this very interesting plant to my old and valued correspondent, Mr. Thompson, of Ipswich, who has for,so many years contributed objects of value and interest to this work ; he sent it in September FEB. lst, 1887, : of last year, and informs me that his plants are seven or eight years old. Its native country is Reverchon in Texas. Drscr. Whole plant more or less scabrid, with short white persistent prickles. Stem simple, two to four feet high, very robust, terete, but channelled when dry.

Heads sessile in the axils of the floral leaves or stoutly peduncled, three and a half inches across the rays, the terminal head often produced in a naked peduncle three to four inches long. Involucre subglobose, one to one and a quarter inch in diameter ; bracts very rigid, broad, scabrid © — and ciliate, acuminate or produced into long rigid pungent recurved beaks. ay-flowers twenty to thirty, ligules narrowly oblong, two-fid, rather concave, pale straw- coloured or cream-white, young tipped with red-brown ; style-arms revolute.

G. Watsonioides, Baker in Journ. Linn. Soc. vol. xxi. p. 405. This is one of the most interesting of the petaloid mono- cotyledons which have been discovered during the recent exploration of the regions round Mount Kilimanjaro by Messrs. Thomson and Johnston. In botanical characters it is nearly allied to well-known Cape species, Gladiolus Watsonius of Thunberg (figured Bor. Mac. tab. 450), but it is quite different in leaf and stature. From Mr. Johnston’s notes it appears to begin at a height of 8500 feet above sea-level in ascending the mountain, and to continue in considerable plenty up to 11,000 feet; and he collected at a height of 13,000 feet a dwarfed form with smaller flowers than in the type and narrow leaves with convolute edges. The seeds (by means of which it was brought into cultiva- tion) have a very broad wing. Our drawing was made ~ from a plant that flowered at Kew in June, 1886. Duscr.

H. calophylla, Parish and Reichb. f. in Lond. Journ. Bot. vol. xii. (1874) p. 197 ; Reichb. f. in Otia Bot. Hamburg. p. 38. Hemipilia is a very curious little Indian genus, of which only two species have hitherto been discovered, that here figured, and the type, 1. cordifolia, Lindl., which was found in Nepal by Wallich upwards of half a century ago, and has since been collected in the North-Western Himalaya by Falconer, Strachey and Winterbottom, and others, at an ‘elevation of 7000 feet; it differs from H. calophylla in the subcordate base of the leaf, stout scape, more numerous and more crowded flowers, with a longer spur and smaller lip. The genus is closely allied to Habenaria, differing however a good deal in habit, and remarkably in the long upcurved rostellum. H. calophylla is a native of Moulmein, in Tenasserim, where it was discovered by Mr. Gilbert, whose specimens were, however, too imperfect for determination and description. The indefatigable Rev. C. Parish rediscovered it in August, 1873, growing in limestone rocks, and for- warded specimens and a drawing to Kew, which enabled Prof. Reichenbach to refer it generically to the previously monotypic Hemipilia, and to describe it with completeness. Probably other species of the genus occur in the Kastern Himalaya, for such plants, with lurid leaves and flowers, FEB. 1st, 1887. growing close to the ground amongst other herbage, in jungles and forests, are with difficulty detected. Mr. Parish observes that the flowers are sometimes wholly . purple. The specimens here figured were sent to the Royal Gardens by Mr. Peché of Moulmein, and flowered in July, 1886. Descr. Root a tuber.

The genus Adesmia, though containing upwards of eighty species of shrubs, has not hitherto found favour in the eyes of horticulturists, and indeed the few species hitherto figured in British horticultural works (Bot.

To these the subject of our plate forms a striking contrast, for A. - balsamica is both a graceful and very beautiful shrub; its balsamic odour, delicate ramification and foliage, and abundant golden flowers together render it a most attrac- tive shrub for the green-house, if not for the open air, in at any rate the milder parts of England and Ireland. It isa native of Chili, and appears to be abundant on the hill-sides near Valparaiso, from whence there are specimens in the Herbarium from numerous contributors. Ciaude Gay . describes it as the most valuable of all the Adesmias on account of its exquisite balsamic odour, which in its native country can be perceived at a great distance, and it is also a reputed medicine. Specimens of this beautiful plant were sent for figuring in the Boranican Macazine by Sir George MacLeay, _ K.C.M.G., who flowered it in his rich conservatory at FEB. lst, 1887. ? Pendel Court, Kent, in March of last year. The balsamic odour is very perceptible even when dry, but doubtless it ‘ is much more developed on hill-sides under the bright skies of a Chilian summer, than in an English green-house in the month of March. .

S. coloratus is an ally of S. Wallichii, which was ficured in this work under the name of Goldfussia Thomsoni (Tab. 5119), which has, however, much fewer flowers, with a curved deep red-purple corolla. S. coloratus is a native of the Kastern Himalaya, at elevations of 2000 to 5000 feet, in Sikkim and Bhotan, where it has been gathered by C. B. Clarke, and it is abundant in the Khasia Mountains, south of Assam, whence Wallich’s collectors first procured it, and where I found it abundantly at elevations of 3000 to 4000 feet, attaining 10 feet in height, with a panicle two to three feet long, and nearly as broad.

This is one of the most attractive and interesting hardy garden shrubs that has been introduced for many years, and though introduced nearly twenty years ago, is rarely seen except in the botanical establishments or the gardens of those in search of novelties. It was discovered by the now venerable Dr. Bunge, formerly Professor of Botany at Dorpat, near Pekin, some sixty years ago, on the occasion of his accompanying an overland mission to that capital from St. Petersburg; but was not introduced till Father David, the most laborious and successful of all explorers of the Chinese Flora, sent seeds.to the Jardin de Plantes at Paris about twenty years ago. According to a statement in the “ Gardener’s Chronicle,’ Father David sent the plant in 1868, and as it. flowered and was figured in the “ Flore des Serres’? in 1872, it must have been transmitted to Paris in a living state. Xanthoceras sorbifolia is a beautiful free-flowering bush, with the habit of the Bladder-nut (Staphylea pinnata), to which it is allied. I am indebted to Mr. Lynch, of the Cambridge Botanical Gardens, for the fine specimens here ficured, with flowers of both sexes, and where it blossomed in May, 1886, the females appearing a few days after the MakCH Ist, 1887. males. The leaves were fully developed in July. For the fine fruits I am indebted to the kindness of continental correspondents; the apple-shaped ones were received in August of last year from M. Max Cornu, of Paris, and were ripened in the Jardin de Plantes. The pyriform ones were received in October from M. J. Van Volxem, of Brussels. The seeds are described as being eaten by the Chinese. . Desor. A deciduous glabrous or puberulous shrub or small tree, copiously leafy. Leaves opposite, eight to twelve inches long, pinnate; petiole short and rachis slender, nearly terete; leaflets alternate, sessile, linear-oblong or oblong-lanceolate, acute, coarsely serrate, the tips of the - leaflets and serratures apiculate, dark green above and glossy, paler beneath. Flowers in copious lateral racemes, eight to ten inches long, from shoots at the sides of the branches, appearing before the leaves, at first suberect, then drooping ; peduncle short; rachis stout; bracts oblong, obtuse or subacute; pedicels a quarter to one-third of an inch long, rather stout. Sepals five, oblong, obtuse, green. Petals spreading and recurved, spathulately obovate, white with blood-red streaks at the base.

It has since been sent home in a dried state by Dr. Meller and Mr. John Buchanan, and in 1883 we received living corms from Mrs. Monteiro. It is a near ally of the well-known Anomatheca cruenta of Natal, but the flowers are much larger. Mr. Bentham has now reduced Ker’s genus Anomatheca to Lapeyrousia, and here again we get a large characteristically Cape genus, represented in Angola and the mountains of Tropical Africa by a few distinct specific types. Our drawing was made from a plant that flowered at Kew in October, 1886. Drscr. Corm small, globose; outer tunics formed of fine brown nearly parallel fibres.

The expeditions sent by the Russian Government to the regions of Central Asia have resulted in the discovery and introduction into the gardens of St. Petersburg of an astonishing number of hardy herbaceous plants, which have been most liberally distributed to all European gardens ; and to none of the intrepid explorers of these inhospitable regions are we more indebted than to Dr. Albert de Regel, the talented son of the excellent and able Director of the _ Imperial Botanical Gardens of St. Petersburg. Amongst these novelties the genus Corydalis holds a conspicuous place, and as most of the species are early spring flowers, when there is little else to grace the garden, they are welcome to horticulturists. Dr. Regel, who describes this plant in the ‘‘ Gartenflora,” says of it that it is ‘allied to C. longiflora, which latter may be distinguished by the more simple stem, by the bracts equalling or exceeding the pedicels of the flower, by the boat-shaped tips of the corolla, which are not spread out, by the subulate acute spur, and by the linear-oblong pods. 2 CO. Kolpakowskiana was found in 1877 by Dr. Albert de Regel in Western Turkestan, near the town of Wernoje, near the river Almatiuka, and is stated to vary in the _ MaRcH Isr, 1887. colour of the flowers from white to pale rose-colour, variegated with purple, and a white throat. In the figure given in the “ Gartenflora,” the flowers are represented of a rather muddy rose-colour, much deeper than in the figure here given, and a white flower is also represented. The foliage, too, is far more luxuriant in the St. Petersburg than in our specimen. The specific name is that of the | Military Governor of the province where the plant was found. Mr. Elwes gave me the specimen here figured, which flowered in a frame with him in April, 1867. Descr. A low glaucous, quite glabrous succulent tuber- ous herb. Stem four to eight inches high, sparingly branched from the base, and sparingly leafy.

Racemes four to six inches long, erect, slender, lax-flowered ; bracts green, oblong, obtuse, shorter than the slender pedicels. Sepals very minute and of irregular form. Corolla gibbous at the base, three-quarters of an inch long from the tip of the lips to that of the spur, white or pink with a purple throat; lips short, equal, spreading, ovate, concave, but with the margins expanded or slightly reflexed ; spur ascending, slightly curved, about twice as long as the limb of the corolla; tip more or less decurved, obtuse.

I have advanced this as a new species with much hesita- tion, because it was sent by Mr. Ford from the Hongkong Botanical Gardens under the’ name of B. fimbristipula, Hance (in Lond. Journ. Bot. 18838, p. 202), and because it agrees with the character of that plant in so many particu- lars that it appeared to me possible that it might be a gigantic form of it, with characters acquired under cultiva- tion. On referring, however, to the Kew Herbarium, I find authentically named specimens of B. fimbristipula from Lofaushan (on the coast opposite to Hongkong) which > show it to be a diminutive very slender little species, two to three inches high, with an ovate cordate acuminate sharply doubly-toothed leaf of a deep red purple colour, and a one- or two-flowered scape. The Lofaushan specimens agree very well with Hance’s description, except that I do not find the under surface of the leaf to be lepidote, and that the outer male sepals are orbicular rather than oblong, and that the petiole is sometimes longer than the limb of the leaf. Specimens from Tingushan, on the Canton river, also in the Kew Herbarium, and cited as B. jfimbristipula by Hance, are many times larger than the above, with a branched cyme as in B. cyclophylla, but the leaves are of the same MARCH lst, 1887. form and toothing as fimbristipula. Another difficulty 1s to determine the section of the huge genus to which this species should be referred. It agrees with none in De Candolle’s monograph (Prodr. v. xv. pars. i.). According to his Clavis (p. 403) it should fall into Dysmorphia, with two Peninsular Indian species (B. crenata, Dryandr., and B. canarana, Miq.); but these are described as having anthers dehiscing by pores, four to five sepals in the female flower, connate styles, and inflated capsules. Hance supposes his B. fimbristipula (with which this must go) to be most nearly allied to B. parruliflora, A. DC., which belongs to the section Parvibegonia, and which should have four to five segments in the female flower, and deciduous styles. According to the grouping of the species sketched out in the “ Genera Plantarum,” it falls into the fourth series, and would be included in an enlarged view of Platycentrum (inclusive of Knesebeckia). Its nearest ally in floral structure appears to me to be B. sinensis of A. DC., a caulescent species of very different habit, referred by A. de Candolle to Knesebeckia. A similar species to B. fimbristipula, of which leaves are preserved in the Kew Herbarium, is extensively used by the Chinese as a drug. ‘The leaves are of a brilliant red- purple colour.

Those who frequent the Succulent House at Kew have _long been familiar with the Ceropegia Sandersonie (Bor. Mac. t. 5792), which, growing in a pot, was trained up a rafter on the left-hand side on entering, and which attracts attention by its curious long green flowers, expanding into the form of a trumpet, surmounted by a fringed green spotted canopy, supported on five short legs. No second species at all lke it of the extensive genus to which it belongs was ever known till 1884, when the tubers of that here figured were sent to the Royal Gardens by Mrs. Monteiro, of Delagoa Bay, widow of that able naturalist J. Monteiro, the author of the best books ever written on the Natural History of Tropical Africa.* C. Sandersonie, just referred to, is a native of Natal, and was named in honour of a lady who, and whose husband (the late J. Sanderson, Esq.), were active contributors to the Royal Gardens. It seems, therefore, appropriate that its near ally should bear the name of the lady to whom the horticultural world is indebted for this singular plant. C. Monteirow was received in 1884, and flowered in July, 1886. It comes from Delagoa Bay, a locality a good way * “ Angola and the River Congo,” by Joachim J. Monteiro. 2 vols. — Macmillan & Co. 1875.

Of the South American genus Clavija, some twenty-tive species are described, but with none of them does the plant here figured agree. It comes near to a Venezuelan one collected in Ocafia (New Grenada) by Purdie, which differs in the shorter petioles and strongly serrated reticu- latedly veined leaves; and to the C. Hookeri, Alph. DC. (C. spathulata, Hook. Ic. Pl. t. 140, not of R. and P.), of Peru, which is a much more slender plant with very small flowers. From all the three species already figured in this Maceazine it differs widely; there are C. ornata, Don (Tab. 4922), C. fulgens, Hook. (Tab. 5626), and C. macrophylla, Miquel (C. Riedeliana, Regel Gartenfl. t. 663) (Tab. 5829). ; I ae named it after the excellent botanist who sent seeds of it to Kew in 1879, Prof. Ernst, of Caraccas.

H., sanguinea, Engelmann Bot. Wislizenus’s Expedition, p. 23; Gray Plant. . Wright. pt. ii. p. 63; Walp. Ann. vol. iii. p. 897. This, as Gray observes, is by far the handsomest species of the genus, which is itself, I may add, a very unpretending one, and in which so really pretty a plant as this was not to have been expected, especially as, except in Hscallonia, the bright reds are rare in the Order to which it belongs. It is curious, and a further instance of the unattractive features of the Heucheras, that though no fewer than fifteen species, all North American, and all presumably hardy, are enumerated in Watson’s ‘‘ Index of North American Botany,” and though several have been cultivated in this . country, one only had been, previous to this, figured in a horticultural work; this one is H. cylindrica, Dougl. (Botanical Register, t: 1924). The original species, how- ever, the Linnean H. americana, appears in a plate of Hill’s ‘Vegetable System,” vol. xii. t. 43, f. 1,.as the Dingy Wellwood, published so long ago as 1761. There is another species which from its specific name may be supposed to deserve the attention of horticulturists; it is the H. rubescens, Torrey, a native of California; its flowers are described as pale pink. H. sanguinea isa native of rocky places on the Pacific slope of the South-Western United States of America, Arizona, and New Mexico. It was introduced into Europe by Mr. Ware, of Tottenham, and the specimen here figured flowered in the Rock Garden at Kew in June, 1886, apRin Ist, 1887. Duscr. Rootstock stout, woody. Leaves sparsely pilose _ with long spreading hairs, petiole three to six inches long, very slender, hirsute towards the base; limb two to two and a half inches in diameter,.membranous, orbicular, deeply cordate at the base with’a narrow sinus and rounded lobes, pubescent on both surfaces, margin shallowly five- to seven- lobed, lobes with three to five very broad mucronate teeth, deep green above, paler beneath. Scape twice as long as the petioles or more, very slender, pilose below, glandular- pubescent above, as is the panicle, naked or with a minute narrow entire or pinnatifid leaf. Panicle with the top and slender branches drooping and often secund ; bracts small, the lower green and pinnatifid, the upper slender entire and coloured. Flowers four to six at the ends of the branches, half an inch long, pendulous from short slender pedicels, scarlet, glandular-pubescent ; bracteoles slender, linear. Calyx campanulate; lobes short, rounded, glandular- pubescent without and within. Petals minute, almost included, linear-spathulate. Stamens short. Ovary half- superior; styles short.—J. D. H.

The vast genus Chrysanthemum, including as it now does Pyrethrwm and a host of monotypic or oligotypic genera, contains upwards of 120 nominal species, of which Bentham considers that about 80 may be regarded as well established. The dividing these into sub-genera and sections is a great difficulty, founded as such divisions are chiefly on the varying form of the pappus. The subject of the present plate has been referred to Coleostephus, of which the type is C. Myconis, L., and also to another genus Glossopappus, which hardly differs. OC. multicaule is a native of various parts of Algeria; it was first found in the Oran province by Desfontaines, and has since been collected at Biskra and elsewhere growing in sandy fields, &c. Judging from a rather insufficient example, it extends to Marocco, whence a specimen collected at Tangier by Broussonet is in the Hookerian Herbarium at Kew. I am indebted to Mr. Lynch, of the Cambridge Botanical Gardens, for the fine specimen figured here, which is much APRIL IsT, 1887. ; larger, more branched and succulent than are native ones in the Herbarium. It flowered in July and August. Descr. A glabrous glaucous annual, with many simple or branched stout, terete, erect or ascending stems six to twelve inches high. Jeaves succulent, very variable, sometimes linear-spathulate, one to three inches long and | one-half to three-fourths of an inch broad, and coarsely toothed or lobulate, at others much shorter and trisect or pinnatisect with few very narrow linear acute entire seg- ments about a line broad. Heads solitary at the ends of the stems or branches, long-peduncled, one and a half to two and a half inches broad, golden-yellow. Involucre hemispheric, outer bracts oblong, green, with hyaline margins, inner with very large rounded hyaline appendages. Ray-flowers twelve to twenty, tube very short; limb very broadly oblong, obscurely crenate at the tip. Disk-flowers very numerous, outer shortly flagon-shaped, base almost cordate, contracted at the minute five-toothed mouth, innermost smaller, nearly tubular. Achenes of the ray short, very broad, dorsally deeply furrowed, and with three or four ventral thick wing-like ribs crowned by a hyaline truncate and obliquely cleft tube;—of the disk shorter, with two oblong parallel ventral swellings crowned with a scale or annular corona.—J.

H. microcalyx, Baker in Flor. Brit. Ind. vol. ii, p. 147. This very handsome plant is a near ally of the common Sainfoin, Hedysarum coronarium, L., but is a far more beautiful species, a very free flowerer, and well adapted for the climate of Great Britain. It is confined tothe Western Himalaya, where it extends from Garwhal, the province west of Kumaon, to Cashmere, at elevations of 11,000 to 13,000 feet. It was discovered by Falconer half a century ago, but remained long unpublished. The plant was raised from seed and flowers in June. Descr. A tall nearly glabrous leafy shrub; branches stout, herbaceous, fistular. Leaves a foot long and under, rachis slender; pinne eight to ten pairs, three-quarters to one and a half inch long, opposite, petiolulate, oblong or ovate-oblong, obtuse or acute, when mature glabrous or sparsely hairy beneath, young softly appressedly hairy, nerves very many, slender; stipules connate in pairs, mem- branous, sheathing; simple or bifid, the lobes sometimes elongate, uppermost on the young shoots sometimes two inches long, sheathing the young leaves and racemes. _ Racemes axillary, a foot long and under, very long- _peduncled, many-flowered ; bracts membranous, subulate ; . apni Ist, 1887. a flowers shortly pedicelled, an inch long, bright violet-red. Calyx hemispheric, minutely bibracteolate, obliquely trun- cate, five-toothed, the lower tooth rather the longest. Standard narrowly oblong-obovate, emarginate, equalling the narrow linear wings which have decurved points and long spur-like basal lobes; keel-petals much larger and longer than the wings and standard, dimidiate-oblong, obtuse. Filaments glabrous; anthers minute. Ovary lanceolate, stipitate, glabrous; style filiform; stigma minute. Pod stipitate, biarticulate, joints quite flat, oblong, one-half to two-thirds of an inch long, with a thin flat margin and reticulately nerved faces; pericarp very thin.

M. involucrata, FE. Meyer in Herb. Drege; Harv. and Sonder Fl, Cap. vol. ii. p- 491; Baker in Saunder’s Refug. Bot. vol. iv. t. 223. This elegant climber seems to be a common plant in the neighbourhood of Durban, where it was discovered by the German collector Drege, and has since been found by_ many collectors. It was introduced into cultivation by Mr. Thomas Cooper, a collector for the late W. Wilson Saunders, HEsq., F.R.S., who raised it from seeds in his celebrated garden at Reigate in Surrey about twenty years ago, and figured the plant in his “ Refugium.” The specimen here figured flowered in the Water Lily House at Kew in July, 1886, and fruited profusely, forming a very attractive feature in the house. Drscor. An extensive glabrous climber; stem very slender, copiously branched and festooning bushes and buildings with its annual growths; branches almost filiform. Leaves one and a half to two inches in diameter, nearly orbicular in outline, or very broadly ovate with a deeply cordate base, membranous, bright green, five-lobed, lobes ovate with a rounded sinus and a few broad apiculate teeth, the terminal lobe sometimes again three-lobed, petiole one- fourth to one inch, slender; tendrils simple, capillary, - sometimes six inches long. Male flowers solitary in all the APRIL Ist, 1887. ‘upper axils; peduncle one to four inches long, slender, bearing an orbicular white bract, one-half to an inch in diameter, veined with green beneath the flower. Male flower sessile in the bracts, nearly two inches in diameter. Calyx-lobes orbicular, green. Corolla pale yellowish with three broad greenish spots on the short tubes and extending as broad veins on to the base of the five large orbicular crenate rounded lobes.
