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, 4 in. deep, cut down nearly to the base, the teeth seta-

foot or more long, erect or diffusely branched from the base, the branch- 
lets slender, angular, moderately silvery. Stipules minute, setaceous. 
Petioles }~3 in. long. Leaflets usually 2 pairs, lateral ones opposite, 
distant, nearly sessile, all linear-lanceolate, 1-14 in. long, 2-8 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 }—-}in. long. Brac- 
teoles setaceous, deciduous, exceeding the short silky pedicels. Calyx 
silky, 4 in. deep, cut down nearly to the base, the teeth setaceous, the
