upper part densely silky, hairs bright brown, adpressed, and rather 

 short. Stipules small, linear. Leaves nearly sessile, with three sub- 

 sessile linear-oblong- leaflets, the central one 1J-2 in. long-, |-J in. 

 broad, bluntish with a mucro, lateral ones generally smaller, upper 

 surface nearly glabrous, lower finely silky. Flowers in dense oblong 

 heads terminal on the main stem and branches. Calyx in flower 4 lines 

 long, the two bracts which are attached near the base lanceolate, half 

 as long as the calyx ; teeth lanceolate, the three upper reaching half- 

 way down, two lower ones narrower and deeper, both tube and teeth 

 densely clothed with long bright-brown silky pubescence. Corolla 

 about equalling the calyx, yellow, standard \ in. broad, wings rather 

 shorter, keel much and suddenly upcurved. Pod sessile, roundish-
