32. I. sessiliflora, DC. Prod. ii. 186. Stem a foot or more long, 
herbaceous, procumbent or suberect, copiously and diffusely branched

silvery. Stipules linear, often faleate. Petioles 4-2 in. long, spreading. 
Leaflets 7-11, obovate, } in. long, apex rounded mucronate, the lateral 
ones distant, opposite or alternate, sessile or the lowest short-stalked, 
both sides, especially the lower one grey-green and permanently silvery. 
Clusters dense, sessile, rounded, + in. broad, about 12-flowered. Calyx 
subsessile, very silvery, a line deep, the teeth setaceous, reaching down 
nearly to the base. Corolla pale rose, not more than equalling the 
calyx. Pod sessile, linear, } in. long, 1 line broad, mucronate, silky, 
slightly torulose, about 6-seeded.

33. I. trigonelloides, Juub. et Spach. Illust. t. 482. Stem 6-12 in. 
long, herbaceous, erect, copiously branched from the base, the branches 
erecto-patent, silvery throughout. Stipules lanceolate acuminate. 
Petioles 3 in. long, erecto-patent. Leaflets 3-5, obovate, 3—3 in. long, 
4-§ in. broad, apex rounded, mucronate, lateral ones sessile, distant, 
opposite, both sides glaucous, and rather thickly coated with adpressed 
silvery hairs. Clusters tin. broad, dense, rounded, sessile, 12—20-

~272. I. eraginis, Schweinf. F1. £Ethiop. 11. 
Nile Land. Abyssinia, Schimper ! 
General habit and texture of J. sessiliflora, but more loosely and copiously silvery ; 
the leaflets fewer, and pod like that of enneaphylla. It has been gathered in Scinde 
by Dr. Stocks. 
34. I. arenaria, A. Rich. Fl. Abyss. i. 183. Stems erect, herbaceous, 
only 2-8 in. high, densely branched from the base, with erecto-patent 
silky branches, Stipules small, linear. Leaves pee or with one or 
even two pairs of leaflets, which are obovate, half an inch long by 
about half as broad, apex rounded, mucronate, both sides glaucous, and 
fueay but not densely argenteous. Flowers in subsessile ab- 
reviated racemes of 2-6 each from the axils of the leaves. Calyx
