32. I. sessiliflora, DC. Prod. ii. 186. Stem a foot or more long, 

 herbaceous, procumbent or suberect, copiously and diffusely branched 

 from the base, the branches slender, wide-spreading, angular, moderately 

 silvery. Stipules linear, often falcate. Petioles J-§ 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, J in. long, 1 line broad, mucronate, silky, 

 slightly torulose, about 6-seeded.

33. I* trigonelloides, Jaub. 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 \ in. long, erecto-patent. Leaflets 3-5, obovate, J— | in. long, 

 J-| in. broad, apex rounded, mucronate, lateral ones sessile, distant, 

 opposite, both sides glaucous, and rather thickly coated with adpressed 

 silvery hairs. Clusters J in. broad, dense, rounded, sessile, 12-20-

Nile Land. Abyssinia, Schimper! 



General habit and texture of 1. 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 2-3 in. high, densely branched from the base, with erecto-patent 

 silky branches. Stipules small, linear. Leaves simple, 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 

 permanently but not densely argenteous. Flowers in subsessile ab- 

 breviated racemes of 2-6 each from the axils of the leaves. Calyx
