Prostrate suffrutex 20-50 mm tall, densely to laxly matted, much branched. Stems slender, terete to ribbed, sparsely to moderately strigose with whitish biramous hairs, glabrescent later, reddish-maroon; stoloniferous, often rooting from nodes, arising from a woody rootstock. Leaves alternate, digitately trifoliolate, petiole 2-8 mm long, scattered with pearl bodies at base of leaflets. Stipules 1-2 mm long, up to 0.5 mm wide at base, lanceolate, attenuate, falcate, often recurved at apex, ± membranaceous, gland-tipped, reddish. Stipels absent. Terminal leaflet 1.5-5-5 mm x 1-3 mm, obovate, apex emarginate, truncate or rounded, base cuneate, upper surface glabrous or sparsely appressed strigose, paler than below; lower surface more densely strigose and slightly rugose; margins somewhat thickened, often appearing slightly involute, often reddish; lateral leaflets similar. Racemes (10)20-70 mm long, many times longer than the subtending leaf, including a peduncle of (6)11-55 mm, becoming flattened, appearing soft-tissued on drying; ±3-8 flowered; bracts 0.5-1.5 mm long, lanceolate-subulate, recurved at apex, caducous. Pedicels 0.75-1.5 mm long, becoming recurved in fruit. Flowers 4.5-6.5 mm long. Corolla vivid fuchsia-pink. Calyx 1.5-2.5 mm long, lobes triangular, 0.75-1.4 mm, ± equaling the tube, ± sparsely strigose appressed. Standard 5.5-6.5 mm long, up to 5 mm wide, broadly obovate, tapering to a short claw at the base; blade sharply reflexed upwards for distal half of length; apex rounded to emarginate; dorsal surface glabrous, often with translucent, short stripes. Wings 5-6 mm long, unguiculate, shortly clawed at base, asymmetrically obovate towards apex. Keel petals 5-6.5 mm long, valvately connate distally, lateral spurs to 1 mm long, distal margin curving upwards to base of the keel to an obtuse apex; claws ±2 mm long, broadening from the base. Stamens 4-5 mm long, alternately long and short, the 9 fused stamens free for ±1 mm distally; anthers uniform. Ovary densely strigilose laterally, glabrous along upper margin; stigma capitate. Pods (9)11-15 mm long, up to 3.5 mm wide, cylindrical, inflated, shiny, reddish-green becoming reddish-brown, sparsely strigose, explosively dehiscent with the valves twisting. Seeds 4-6, 1.5 x 1.5 mm, ± quadrate, dark green.
