An erect or ascending, rarely decumbent, shrub or shrublet from less than 0.2 to more than 2 m tall, sparingly to rather densely branched. Young branches villous or tomentose. Leaves of long-shoots alternate. Leaflets linear or subulate, (1-)3-10 mm long, subterete, acute or acuminate, rigid or weak, smooth, or with prominent hair base tubercles, greyish to clear green, with spreading or short, half-appressed hairs. Inflorescence unifloral or bifloral on branch tips and, sometimes on lateral short-shoots. Bract simple, subulate or filiform, similar to leaflets of vegetative leaves, 1-7(-9) mm long. Pedicel very short, tomentose. Bracteoles similar to the bract, 1.3-8(-9.5) mm long. Calyx tube short-or long-tomentose or almost sericeous; lobes from almost ovate to lanceolate or linear, 2-10 mm long, 0.7-2.1 mm broad at the base, acute or acuminate, rigid or weak, straight or recurved, glabrous or with sparse hairs, with ± prominent midvein and margins, often with prominent (hair base) tubercles. Petals pale yellow to orange-yellow (sometimes when fading, ferruginous). Standard blade broadly obovate, (7.5-)8.5-14 x 8-11.5 mm, tomentose (sericeous) on the back, glabrous on the front, apex obtuse or (in some populations) produced into a tip up to 2 mm long. Wing blades narrowly elliptic, (5.3-)6-9.5 x 2.5-4 mm. Keel blades lunate, (6.7-)7.5-11.5 x 4.8 mm, glabrous (or with a few hairs on basal lower parts); upper margin slightly concave to ± straight. Pistil: ovary generally pubescent. Pod triangular-ovate, 6-8 x 3.8 mm, ± tomentose, smooth, brown when ripe.
