Erect or ascending shrub up to 1 m tall. Branches rigid, densely and shortly villous, becoming fissured with age. Leaves digitately trifoliolate, shortly petiolate, appearing to rise at the edge of the stipular sheath. Stipules increasing in size from 3-5 mm long, 3-4 mm wide at the base of short lateral shoots but up to 11 mm long and 8 mm wide near the apex of such shoots, adnate to the petiole, ovate becoming broadly ovate, glabrous, involucrate, 2-cleft with one half shortly bifid, light green, paler on lower parts, glabrous; petiole 0.2-1.0 mm long (free part), villous. Leaflets 2-7 mm long, 1.5-4.0 mm wide, obovate, equal, base cuneate, apex acute to cuspidate, conduplicate, glabrous, pale green. Inflorescence pseudo-umbellate, terminal on short lateral shoots; 4-6-flowered; pedicels 3-6 mm long, elongating in the fruiting stage, villous, merging gradually into the calyx, hidden by the sheath-like stipular involucre of the uppermost leaf (subtended by a longer internode than the previous ones). Flowers 10-12 mm long, fresh flowers pale yellow flushed with pink or purple on the back of the standard and the distal parts of the wings but becoming more pink or purple with age. Calyx 6-8 mm long, tube 4-5 mm long; vexillar keel lobes mutually coherent to a tripartite lip; teeth much narrower and 1 mm shorter than the vexillar teeth, but with the keel tooth narrowest; finely pubescent on inner face of the teeth and sparsely silky on outer face of the teeth, elsewhere glabrous; pale yellowish on the basal part and more or less purplish on the teeth and distal parts of the tube in dry state. Standard 11-12 mm long, 7.0-7.5 mm wide, claw 4 mm long; blade ovate, apex obtuse, glabrous except along the midrib of the back, auricles and appendage absent. Wing petals 11-12 mm long, 3.6-4.0 mm wide, claw 4 mm long; apex rounded; auricle scarcely developed, rounded; sculpturing upper basal and upper central, angled upwards, intracostal in three uneven rows, lunullate distally, becoming coarser basally; outer face with a medial line of scattered hairs. Keel petals 1.5-2.0 mm long, 3.5-4.0 mm wide, claw 5.0-5.3 mm long; apex obtuse, pouched along the midline near the base of the blade; pubescent all over but more so on the lower central and lower distal parts, auriculate. Androecium 12 mm long, stamens sheathed, slit on the adaxial side; anthers dimorphic, with 4 linear-oblong basifixed anthers, (1.0-1.2 mm long), alternating with 5 ovate dorsifixed anthers (0.7-0.8 mm long), median anther slightly longer than the short anthers. Pistil 1.5 mm long; ovary 7 mm long, linear, densely pubescent, subsessile, merging into the upflexed style; ovules 6-7; style glabrous beyond point of flexure, height of curvature, 3.0-3.5 mm; stigma small, apical, capitate. Fruit 28-34 mm long, 4.5-5.0 mm wide, narrowly oblong, slightly curved, densely villous, glandular, dehiscent, somewhat constricted between the oblique seeds. Seeds 2.5-2.6 mm long, 1.9-2.3 mm wide, oblong-ovate; mottled, sheen dull, hilum ovate, recessed, situated on the short side, rim aril visible, regular, funicular remnant visible; micropyle hidden.
