decumbent, suffruticose, glabrescent or villoso-pilose; stipules in pairs, obliquely ovate or lanceolate; leaflets cuneate-oblong, sub-glabrous or silky, thickish, longer than the petiole; peduncles much longer than the leaves and opposite them, one flowered; bracts minute, setaceous; vexillum densely pubescent; legume turgid, patently hairy. Nearly glabrous, or thinly or thickly clothed with long soft hairs. Stems 6–12 inches long, spreading on the ground. Petiole 1/4– 1/3 inch long, channelled; leaflets 1/2– 3/4 inch long, tapering at base, broader upwards, blunt or mucronate, midribbed. Stipules nearly as long as the petioles, sometimes but one, lanceolate. Peduncles 2–4 inches long, articulate and bracteate below the flower. Calyx 3 lines long, softly villous, deeply cut, the lowest segment subulate, the rest lanceolate, connate beyond the middle. Vexillum densely hairy; the keel shorter than the wings. Legume 1 inch long, 2 1/2 lines wide, the ventral suture elevated and often tuberculate. Drege's specimens are much less hairy than E. & Z.'s. Var. β. chiefly differs in the narrower and more acute leaflets and longer calyx lobes.
