76. I. atriceps, Hodk.f. in Journ. Linn. Soc. v. 190. An undershrub 

 2-3 ft. high, the branches firm, subterete, with a few spreading setse 

 when young, glabrous when mature. Stipules setaceous. Petioles 

 very short. Leaflets 9-13, oblanceolate or obovate, §— \ in. long, apex 

 rounded mucronate, lateral ones contiguous, opposite, short-stalked, 

 texture firm, upper surface green, lower glaucous, both very thinly 

 silky. Racemes dense, 1-1 \ 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, f 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, f-J long, the 

 apex rounded and mucronate, the lateral ones opposite, short-stalked, 

 both sides rather densely grey-silky. Racemes copious, dense, 1 J-2 in. 

 long, on erecto-patent peduncles clothed like the stem and from J-l in. 

 long. Calyx densely silky, | in. long, the teeth subulate, reaching 

 down nearly to the base, often black. Corolla reddish, slightly ex- 

 ceeding the calyx. Pods linear-oblong, J-f in. long, straight, hori- 

 zontal, densely clothed with spreading grey or ferruginous often 

 gland-bearing hairs, 2-4-seeded. — I. oligospermia, DC. Prod. I.e. ; Guill. ■

Varies considerably in robustness, the colour of the pubescence and quantity and 

 colour of the setae, which are sometimes a beautiful purple. A plant, of which there is 

 a single specimen in the Afzelian herbarium, gathered by Brass at Sierra Leone, re- 

 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 down 

 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, thinly 

 silky upwards. Stipules linear. Petioles spreading or erecto-patent, 

 under half an inch long. Leaves with 3-5 pairs of leaflets, oblanceo- 

 late, f — J- in. long, the apex rounded and mucronate, the lateral ones 

 opposite, both sides glaucous and thinly silky, and the lower also dotted
