Angraecum (Supplement)
The species of this genus number about forty, and are nearly all natives of tropical or South Africa and the Mascarene Islands. To those described on p. 79, Vol. I., the following should now be added:
A. apiculatum (apiculate). fl. white, in pendulous racemes of about a dozen; spur slender, pointed, about 2in. long. l. distichous, obovate-lanceolate, obliquely acuminate, striated, deep green. Sierra Leone, 1844. A dwarf species, allied to A. bilobum. (B.M. 4159.)
A. a. Dormanianum (Dorman's). A small-flowered variety, having vermilion-flaked ovaries, and vermilion tips to the sepals. 1885.
A. articulatum (jointed). fl. creamy-white, racemose, polymorphous, the filiform spur as long, or sometimes three times as long, as the ovary; peduncles stout. l. cuneate-oblong, unequally bilobed, about 6in. long. Madagascar. A dwarf species, allied to A. bilobum.
A. avicularium. fl. snow-white; sepals and petals lanceolate, cuspidate; lip narrow at the base, oblong, cuspidate; spur filiform, 4in. to 5in. long; peduncle more than 9in. high, bearing fifteen flowers. l. short and broad, cuneate-oblong-elliptic, bilobed at the point, nearly 4in. long. Probably a native of tropical Africa, 1887.
A. bilobum Kirkii (Sir John Kirk's). fl. pure white, having slender, pale brown spurs 2 1/2in. to 3in. long; racemes dropping. l. narrower than in the type, ending in two divergent lobes. Zanzibar, 1882. (W.O.A. iv. 162.)
A. calligerum (callus-bearing). fl. very stiff in texture; sepals ligulate, acute, with a strong, semi-oblong callus on the keel at the very base; petals cuneate-oblong, acute; lip's plate rather ligulate, pandurate, acute, with a long, filiform, acute spur, exceeding the stalked ovary six to seven lines. l. slightly glaucous, ligulate, bilobed. 1887.
A. crenatum (crenate). fl. resembling those of A. Chailluanum in colour and shape, but much smaller (as is also the habit of growth). June and July. West Africa. A rare and distinct species.
A. cryptodon (hidden-toothed). fl. white, in loose racemes; petals ligulate, acute; lip lanceolate; spur white, reddish at base, thrice as long as the reddish-white ovaries. Madagascar, 1883.
A. descendens (descending). fl. white, numerous in a drooping raceme. Madagascar. This differs from A. Ellisii in having a cuneate-ovate, acuminate lip, a shorter, hairy column, a spur more than four times as long as the pedicels, and oblong-ligulate, obscurely bilobed leaves.
A. Eichlerianum (Eichler's). fl. large, solitary; sepals and petals light green, lanceolate; lip white, large, obcordate, with a triangular apiculus in the notch; spur erect, conical, about as long as the sepals. l. distant, oblique, elliptic, obtuse. Stems tall, leafy. Loango, West Africa, 1883. A. fastuosum (proud). fl. ivory-white, scented like tuberoses, numerous, racemose; sepals and petals ligulate-oblong; lip obovate; spur filiform, 2in to 3in. long. l. cuneate-oblong, 3in. broad, blunt and unequally lobed at apex, wrinkled, the margins cartilaginous. Madagascar.
A. florulentum (dark-flowered). fl. one to three in a raceme; sepals lanceolate; petals broader than the sepals; lip oblong-lanceolate, apiculate; spur filiform, one-third longer than the ovary; racemes numerous. l. lanceolate, bilobed, 3in. long. Stem zigzag. Comoro Islands, 1885.
A. fuscatum (fuscous). fl. numerous, in a thin, lax raceme; sepals ochreous, the lateral ones reflexed; petals broader than the sepals; lip white, oblong, acuminate; spur brown, long, filiform, flexuous. l. cuneate-oblong, unequally bilobed. Madagascar, 1883. The habit of this plant is much in the way of A. bilobum. (R.G.1234; R.H. 1887, p.42.)
A. grandidierianum (Grandidier's). fl. ivory-white, about the same size as those of A. Chailluanum: sepals cuneate-oblong, acute; petals spathulate, apiculate; lip cordate-pandurate or cordate-oblong, blunt, with a long, filiform spur; raceme one to three-flowered. l. thick, oblong, obtuse and unequally two-lobed at apex. Comoro Islands, 1887. (R.H. 1887, p.42) SYN. Aeranthus Grandidierianus.
A.Hildebrandtii (Hildebrandt's). fl. orange-yellow; lip oblong, acute; spur filiform, clavate, shorter than the ovary. l. ligulate, unequally bilobed. Comoro Isles. An elegant but small-growing plant.
A. ichneumoneum (ichneumon-like). fl. loosely arranged on a long axis; sepals and petals dirty ochre-white, ligulate, with a curious spur. l. ligulate, dark green, 1ft. long, 2in. broad, unequal at apex. 1887. SYN. Listrostachys ichneumonea.
A. imbricatum (imbricated). fl. sweet-scented, in cluster-like racemes; sepals and petals creamy-white, lanceolate; lip orange and yellow, flabellate, retuse, apiculate, convolute, the spur recurved, blunt, not half as long as the blade of the lip, which it nearly touches. l. leathery, cuneate-oblong, bluntly bilobed. Stem tall, strong. 1887.
A. Leonis (Leon Humblot's). A synonym of Aeranthus Leonis.
A. rostellare (beaked). fl. resembling those of A. fuscatum in shape, but having a distinct, long-linear, ascending, rostellar process, and spathulate, apiculate petals; peduncles numerous, many-flowered. l. cuneate-oblong, bilobed at apex, unusually soft. 1885.
A. Sanderianum (Sander's). A synonym of A. modestum.
