99. I. oligophylla, Klotzsch in Peters 1 Mossairib. Bot. 49. Stem her- 

 baceous, a foot long, copiously and diffusely branched from the base, 

 the branches slender, terete, silvery. Stipules small, setaceous. Pe- 

 tioles J in. long. Leaves with 1—2 pairs of narrowly oblanceolate 

 leaflets, |-1 in. long-, 2 lines broad, apex rounded, mucronate, both 

 sides densely clothed with adpressed silvery hairs. Flowers in long 

 stalked racemes of 10-15 flowers each which equal the leaves, the 

 peduncle 1-2 in. long. Bracts short, cymbiform, acuminate, persistent. 

 Calyx silvery, J in. deep, cut down nearly to the base, the teeth seta- 

 ceous. Corolla about equalling the calyx. Pods deflexed, and then 

 again slightly recurved, linear-mucronate, \ in. long, 1 line broad, 4-6- 

 seeded.

Closely allied to 7". ornithopodioides, but more silvery, with smaller pods, fewer leaf-

100. I. aspera, Perr. in DC. Prod. ii. 229. Stem herbaceous, a 

 foot or more long, erect or diffusely branched from the base, the branch- 

 lets slender, angular, moderately silvery. Stipules minute, setaceous. 

 Petioles J-f in, long. Leaflets usually 2 pairs, lateral ones opposite, 

 distant, nearly sessile, all linear-lanceolate, 1— 1J in. long, 2-3 lines 

 broad, apex rounded, mucronate, both sides glaucous, and permanently 

 thinly coated with strong adpressed silvery hairs. Flowers in axillary 

 racemes 2-3 in. long, of 20-30 each, on peduncles J- J in. long. Brac- 

 teoles setaceous, deciduous, exceeding the short silky pedicels. Calyx 

 silky, \ in. deep, cut down nearly to the base, the teeth setaceous, the 

 two lowest the longest. Corolla rose-coloured, twice as long as the 

 calyx, the standard silvery on the outside. Pods deflexed, straight,
