shrubby, silky and silvery, densely leafy; twigs striate; leaves petiolate, pinnato-trifoliolate, leaflets elliptico-lanceolate or elliptical, glabrous on the upper, silky and silvery on the under surface, mucronate, penni-nerved; stipules lanceolate, equalling the petiole; peduncles terminal and axillary, much longer than the leaves; heads globose, bracteate, dense; bracts ovato-lanceolate, very villous bracteoles narrow-lanceolate; calyces villoso-hirsute, the segments lanceolate, lowest much longer than the rest; ovary glabrous. A small, erect or ascending, slightly branched, half woody shrub, 1–2 feet high, the twigs, under sides of leaflets, inflorescence, and young leaves silvery and silky; the older parts glabrescent. Petioles 1/4–1 inch long. Leaflets 1–2 inches long, 1/2– 3/4 inch broad; the margin slightly recurved. Peduncles 4–5 inches long, erect or spreading.
