An erect or ascending shrub, fairly densely branched, up to c. 0,6 m tall. Young branches short-tomentose, reddish. Leaves of long-shoots opposite or subopposite. Leaflets linear, 3-11 (usually 5-9) mm long, subterete, straight or slightly incurved, acute-acuminate, pale green, smooth and glabrous or with sparse spreading hairs from ± prominent hair base. Flowers solitary or in pairs on the branch tips or solitary on lateral short-shoots. Bract usually trifoliolate, occasionally unifoliolate; leaflets similar to leaflets of vegetative leaves, (3-) 4-10 mm long. Pedicel short. Bracteoles simiÂlar to bract leaflet(s). Calyx tube tomentose; lobes lanceolate or linear, (4-)4,5-9,5 mm long, usually with prominent green margins and prominent midvein, acute-acuminate, glabrous and smooth or with scattered hairs from ± prominent hair base tubercles. Petals yellow. Standard blade obovate, 8,5-11(-12,2) x 7,5-9,5(-10,5) mm, densely sericeous on the back, with an apical, subterete, pointed cusp 0,8-2,2 mm long. Wing blades narrowly ovate or obovate, 5-7(-7,8) x 2,5-3,2 mm. Keel blades lunate, 6,5-8,5(-9) x 3,2-4 mm, glabrous, with nearly straight (or slightly S-curved) upper margin. Wing and keel claws adnate for 1-2 mm to the staminal sheath. PisÂtil: ovary ovate, ± long-pubescent. Pod trianÂgular-ovate, 5-5,5 X 2,5-3 mm, sparsely seÂriceous, brown when ripe. Figure 45:10-17.
