A very curious plant (R ? antennulifera, Baker), gathered by Dr. Meller in Zambesi 

 land, has the ovary and stamens of this genus, but the leaves 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. The 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 brae- 

 teoles are linear, \ in. long, with a long filiform point thickened upwards. The calyx is 

 distinctly stalked, f-f in. long, cleft three quarters of the way down, 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 points 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 appears to be dull yellow, 

 and distinctly exceeds the calyx, the standard being oblong, 3|-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 ;

 oblong, 2-valved, continuous within. Seeds 2 or by abortion 1. —
