In general habit closely resembling Dolichos biflorus. 
A very curious plant (R ? antennulifera, Baker), gathered by Dr. Meller in Zambesi 
land, has the ovary and stamens of this genus, but the Jeaves are unknown, and the 
habit is entirely different from that of any known species. The racemes are from six 
inches to more than a foot long, and arise singly or two or three together from a straight 
terete woody glabrous stem. he axis of the stem is woody in the lower part, straight, 
and clothed with grey pubescence. The flowers extend nearly or quite to the base, the 
lower ones in lax fascicles of three or four together, the upper crowded. The brac- 
teoles are linear, 1 in. long, with a long filiform point thickened upwards. The calyx is 
distinctly stalked, 8-3 in. long, cleft three quarters of the way own, densely clothed 
with firm ascending grey hairs on the outside, the two upper teeth slightly connate, the 
three lower ones lanceolate in the lower part, but the poiuts still more distinctly length- 
ened out than those of the bracts into a filiform awn, thickened towards the apex so as 
to resemble closely the antenna of an insect. The corolla ap ears to be dull yellow, 
and distinctly exceeds the calyx, the standard being oblong, 34-4 lines broad, and the 
wings under 2 lines broad, both about equalling the keel.

Calyx-teeth subequal or the two upper ones slightly connate. Stan- 
dard oblong or obovate, appendiculate at the base with inflexed auricles ; 
wings narrow; keel slightly incurved at the apex, obtuse. Upper sta- 
men free, the others connate; anthers uniform. Ovary sessile, 2-ovu- 
late; style filiform or slightly thickened upwards; stigma small, 
terminal. Pod compressed, ob iquely orbicular, rhomboidal or broad- 
oblong, 2-valved, continuous within. Seeds 2 or by abortion 1.— 
Herbs or shrubs with pinnately trifoliolate or simple leaves, the stems 
not twining in any of the Tropical African species. 
A genus of moderate size, almost confined to South America, Tropical Africa, and the 
ape.
