Tall, much branched sub-shrubs, lower stem prostrate; stem, petioles, rachis, leaf margins and midrib below long-bristly. Leaflets 4-5 pairs, 1-2 x 0.5-0.8 cm, elliptic lanceolate, obtuse at apex with mucronate tip, ciliate on margins; rachis ending in a subulate bristle.
Racemes corymbose, axillary and terminal; bracts lanceolate, 0.5-0.7 cm.
Calyx 0.5 cm long, 2-lipped, upper large, emarginate, lower 3-lobed, ciliate on margins. Petals yellow, 1-1.3 cm long, wing petal with transverse scaly foldings. Pods 4-5 jointed folded and enclosed in the accrescent calyx.
