Leaflets 5-7 x 3 mm wide, obovate but usually partly conduplicate giving an open tubular appearance, flatter in younger plants, straight sometimes arcuate, densely villous-sericeous, terminal leaflet same size as laterals or slightly longer. Stipules 25-30 mm long, fused, villous with longer patent pilose hairs. Inflorescences 1-or 2-flowered. Flowers10-11 mm long, yellow, ebracteolate; pedicel 2.5 mm long, tapering. Calyx 5 mm long, including tube 3 mm long, vexillar teeth broadly triangular, 1.5 mm long, almost equally broad at base, lateral and keel lobes mutually coherent to a lip, fused for two thirds of their length, smaller and shorter than vexillar teeth, densely villous, glabrous inside. Standard 10 x 10 mm; blade emarginate, sericeous on back, glabrous inside; claw 3 mm long, narrow.
