76. I. atriceps, Hook.f. in Journ. Linn. Soc. v. 190. An undershrub 
2-3 ft. high, the branches firm, subterete, with a few spreading sete 
when young, glabrous when mature. Stipules setaceous. Petioles 
very short. Leaflets 9-13, oblanceolate or obovate, 3—} in. long, apex 
rounded mucronate, lateral ones contiguous, opposite, short-stalked, 
texture firm, upper surface green, lower glaucous, both very thinly 
silky. Racemes dense, 1-14 in. long, on firm erecto-patent peduncles 
2 in. long, which like the rachis of the flower-cluster are coated with 
black pubescence. Calyx 2 lines, with dense similar pubescence, the 
teeth linear-subulate, reaching down nearly to the base. Corolla 
purplish, half as long again as the calyx. Pod spreading, linear- 
mucronate, 2 in. long, a line broad, densely clothed with close black 
pubescence, and scattered longer pale brown gland-tipped hairs, 6-8- 
seeded.

77. I. secundiflora, Poir.; DC. Prod. ii. 228. Stem herbaceous 
or slightly shrubby, copiously and diffusely branched, more or less 
densely clothed with spreading grey or ferruginous hairs intermixed 
with abundant deciduous stalked glands. Stipules subulate. Leaves 
subsessile, with 4—6 pairs of leaflets, oblong or obovate, 3—} long, the. 
apex rounded and mucronate, the lateral ones opposite, short-stalked, 
both sides rather densely grey-silky. Racemes copious, dense, 14-2 in.

Varies considerably in robustness, the colour of the pubescence and quantity and 
colour of the setee, which are sometimes a beautiful purple. A plant, of which there 38 
a single specimen in the Afzelian herbarium, gathered by Brass at Sierra Leone, ™® 
sembles this closely in general habit and leaf. It has a longer calyx (12 lines long), 
densely clothed with brown silky hairs, with lanceolate-setaceous teeth reaching dow? 
nearly to the base. No doubt it is distinct, but there are neither good flowers nor fruit. 
78. I. Perrottetii, DC. Prod. ii. 228. Stem a foot or more long; 
herbaceous, moderately stout, trailing, branched from the base, think 
silky upwards. chy seni linear. Petioles spreading or erecto- atent, 
under half an inch long. Leaves with 3—5 pairs of leaflets, oblance0- 
late, 3-4} in. long, the apex rounded and mucronate, the lateral ones 
opposite, both sides glaucous and thinly silky, and the lower also dotte
