Tree up to 25 m high. Stipules foliaceous, acinaciform, falcate, up to c. 15 mm in diam., acuminate, rounded auriculate at base, reticulate glabrous, tardily caducous. Leaves 4-(or rarely 3-)jugate; petiole 1-3.2 cm and rachis 7.7-13.6 cm long, minutely puberulous, glabrescent, or glabrous. Leaflets thinly coriaceous, elliptic or elliptic-oblong, ovate-oblong or sometimes obovate, 3.5-12.5 by 2.5-7 cm, often glabrous, sometimes puberulous on the lower surface when young; apex acute, subacuminate, obtuse, the very tip slightly notched; base obtuse or rotund, sometimes subtruncate or subacute, often more or less unequally sided; petiolules short, up to c. 5 mm, puberulous, glabrescent, or glabrous. Inflorescences paniculate, up to 17(-37) cm long, lateral branches up to c. 3.5(-9) cm long, both rachis and branches densely puberulous; bracts and bracteoles lanceolate, up to 3 mm long, densely puberulous on both surfaces; pedicels short, up to 5 mm, puberulous. Flowers dirty yellow or light brown, margins pink, fragrant. Calyx lobes lanceolate, up to 9.5 by 3 mm, outside unarmed, puberulous, inside tomentose. Petal elliptic or oblong-elliptic, 5-6.5 by 2-2.5 mm; outside densely puberulous in the lower half; glabrous inside. Stamens: united basal parts of the filaments very short; free filaments up to c. 6 mm, slightly hairy; (fertile) anthers various in size, the 2 larger ones ovoid-ellipsoid, c. 3.5 mm long, the others smaller. Ovary subsessile, subrhomboid, c. 3 mm long, densely hairy on the margin, glabrous in the centre, 3-ovuled; style up to c. 10 mm, recurvate, hairy at the base, sparsely hairy in the upper part; stigma terminal, small, capitate. Pods at almost 90° on a short peduncle (c. 1 cm), suborbicular, orbicular, or broadly ellipsoid, 6-9.5 by 5-5.5 cm, flattened, smooth, beak very short, recurvate, c. 5 mm long; 1-or 2-seeded. Seeds suborbicular or broadly ellipsoid, c. 2 by 1.8 cm, smooth, compressed, on a smaller aril (0.85 by 1.2 cm).
