A sparingly branched, somewhat lanky shrub usually 1-2 m tall, with straight, rigid branches terminating in inflorescences. Young branches densely short-tomentose or short-sericeous. Leaves trifoliolate; the long-shoot leaves situated on a tubercular leaf base and provided with one large middle leaflet up to 8 x 2.5 mm and two smaller, lateral leaflets about half as long but nearly as broad. Leaflets linear-oblong or oblanceolate, obtuse to acute, soft, flexible, densely silvery sericeous. Axillary short-shoots with a few leaves soon developed in the axils of the long-shoot leaves, the leaflets appearing clustered. Inflorescence a spike up to ±50 mm long, with 10-35 flowers. Bract oblong or oblanceolate, 2-4 x 0.5-0.8 mm, acute, tomentose-sericeous. Pedicel ±0.5 mm long, sericeous. Bracteoles similar to the bract, ±1.2-3 x 0.2-0.5 mm. Calyx tubular-campanulate, densely short-tomentose, pale; lobes deltoid-triangular, only 0.5-1.5 mm long, acute, tomentose. Petals light yellow. Standard blade circular, 8-9 x 8-9 mm, rounded apically, densely sericeous on the back. Wing blades oblong, 8.5-9 x ±3.5 mm, densely sericeous on most of the outer side; with several rows of minute folds on basal third. Keel blades 7-8 x ±4 mm, lunate, with ± straight upper margin, sericeous on most parts (except along upper margin). Pistil sericeous on ovary and the basal three-quarters of the style; ovules 4. Pod obliquely lanceolate, ±10-14 x 3-3.5 mm, densely white pubescent (quite ripe pods not seen).
