sessile, with 8 subsessile linear leaflets, the central one 2 in. long, 
} in. broad, glabrous above, beneath with adpressed silky hairs. 
Flowers in dense heads of 6—8 flowers, terminal on the main stem and 
branches. Calyx 4 lines long, the bracts linear, not half as long as the 
calyx, teeth lanceolate, three upper ones reaching halfway down, 
lower ones narrower and deeper, both tube and teeth densely clothed 
with bright brown silky pubescence. Corolla bright yellow, slightly 
exceeding the calyx. Pod sessile, round, densely silky, 4-seeded.— Hey-

Stipules small, linear. Leaves nearly sessile, aah three subsessile 
lanceolate leaflets, 1}-2 in. long, 3—$ in. broad, blunt with a mucro, 
lateral ones smaller, upper surface glabrous, lower with fine adpressed 
silky hairs. Flowers in oblong heads of 3-4 each, terminal on the

Doubtfully distinct from the preceding. The leaflets are much broader, and only the 
upper part of the stem is a little silky.
