Young twigs, leaf rachides, petiolules and leaflet midribs sparsely rusty pubescent with hairs c.1 mm long, or almost glabrous. Leaves 3-5(6)-foliolate; petiole 2.5 cm long; rachis up to 6.5 cm long; leaflets ± subcoriaceous, 3-10 x 1.5-5 cm, ovate, elliptic, elliptic-lanceolate or sometimes round, acuminate at the apex, broadly cuneate to truncate at the base; lateral nerves 5-6 on each side; stipules falling very early; petiolules 3 mm long. Inflorescences scented, 15-20 cm long, 5-10-flowered, the rachis with rather long chestnut-brown hairs; bracts very deciduous; bracteoles 2-3 mm long, under 0.5 mm wide at base, linear to spathulate, deciduous; pedicels 10 mm long. Calyx reddish, glabrous or nearly so; tube 3-4 mm long; lobes 0.5-1.5 mm long. Corolla white; standard 1.3 x 1.1 cm, with claw 1.5 mm long; wing blades 12 x 4.5 mm, oblong, with claw 4 mm long; blades of keel petals 11.5 x 5 mm, with claw 4.5 mm long. Filament sheath 10 mm long, with free parts of filaments 4-6 mm long; anthers 0.7 mm long. Ovary glabrous or with few hairs on the sutures, 2-5-ovuled; style c.7 mm long. Pods 5-9(11) × 1.7-3.5 cm, lanceolate or elliptic-oblong, venose when young. Seeds ± blackish, 1.6-2.3(2.7) × 1.2(1.8) × 0.4-0.9 cm, oblong-ellipsoid, subrhomboid or compressed, obscurely striate and pitted.
