An erect, not or very sparingly branched, rod-like shrublet, 0.2-0.7(-1.2) m tall, consisting quite often of a single stem covered by floriferous short-shoots. Branch end sericeous. Leaves of long-shoot consisting of one larger (middle) and two smaller(lateral) flat leaflets situated on an inconspicuous leaf base. Short-shoots, with or without a flower, developed in the axil of these leaves. Central leaflet of long-shoot leaves lanceolate, 4-7 x 1.5-2 mm, acute or obtuse, weak, silvery sericeous, without distinct veins; lateral leaflets half as long or less. Inflorescences unifloral on lateral short-shoots, dispersed on the (often single) stem in a spike-like fashion along up to 0.2-0.3 m length. Bract flat, narrowly lanceolate, ±3 mm long, sericeous. Pedicel very short. Bracteoles narrowly linear or subfiliform, 3.5-4 mm long, sericeous. Calyx sericeous, with lobes narrowly triangular, 3.5-4 mm long, flexible, sericeous. Petals light yellow, the blades sericeous on most of the back or outer side, wing and keel claws ± two-thirds the length of the blades. Standard blade ovate, 9-11 x 9-11 mm, obtuse. Wing blades obliquely ovate, ±10 x 4.5 mm, with a main longitudinal fold and with several rows of minute folds on basal upper parts. Keel blades lunate, ±7 x 3.5 mm, slightly upcurved. Pistil sericeous on ovary and style base; ovules 2. Pod triangular-lanceolate, ±10 mm long, sericeous.
