by botanists—is found all over the tropics of the Old World, 
and is very common in sub-alpine qaneice on the west side of

ANGRZECUM. Syn. #robion. Including Listrostachys. 
The species of this genus number about forty, and are 
nearly all natives of tropical or South Africa and the 
Mascarene Islands.

Vol. Y, 
With the exceptions of A. eburneum and A. sesquipedale 
(see Fig. 45), all the members of this great genus that 
are in cultivation are of dwarf habit, and are suit- 
able for basket or shallow-pan culture suspended near 
the roof-glass. A. Scottianwm should be placed in a 
basket, and the terete stems wound around a block stood 
in the centre, the block having been previously covered 
with living sphagnum. The potting compost required by 
the other members of this genus is a layer of good sphag- 
num, made moderately firm at the top of the basket or 
pan, the remaining portion having been previously filled 
with clean broken crocks. Angrecums delight in a liberal 
amount of moisture at all seasons of the year, both in the 
atmosphere and at the roots. 
To the species described on p. 79, Vol. I., the following 
should be added : 
A. apiculatum (apiculate). A synonym of A. bilobum. 
A. articulatum (jointed). jl. creamy-white, racemose, poly- 
morphous, the filiform spur as long, or sometimes three times as 
long, as the ovary; peduncles stout. 7. cuneate-oblong, un- 
equally bilobed, about 6in. long. Madagascar. A dwarf species, 
allied to A. bilobum. (R. ser. i., t. 55.) 
A. avicularium. jl. snow-white; sepals and petals lanceolate, 
cuspidate; lip narrow at the base, oblong, cuspidate; spur 
filiform, 4in. to 5in. long; peduncle more than Qin. high, bearing 
fifteen flowers. J. short and broad, cuneate-oblong-elliptic, 
bilobed at the point, nearly 4in. long. Probably a native of 
tropical Africa, 1887. 
A. bilobum Dormanianum (Dorman’s). A _ small-flowered 
variety, having vermilion-flaked ovaries, and vermilion tips to the 
sepals. 1885, 
A. b. Kirkii (Sir John Kirk’s). ji. pure white, having slender, 
pale brown spurs 2sin. to 3in. long; racemes drooping. J. nar- 
rower than in the type, ending in two divergent lobes. Zanzibar, 
1882. («W. O. A. iv. 162.) 
A. bistortum (twice-twisted). This species is closely allied to 
A, arcuatum, but has much smaller flowers, which are peculiar 
in being furnished with a loop-curved spur. Western tropical 
Africa, 1893. Syn. Listrostachys bistorta. 
A. calligerum (callus-bearing). /l. 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. J. slightly 
glaucous, ligulate, bilobed. 1887.
