Large trees, to 50 m high and 94 cm dbh; twigs pale or greyish to dark brown, lenticellate, hairy when young. Stipules small, dropped early. Leaves including petiole up to 5 cm long, alternate, imparipinnate; petiolules 3-4(-7) mm long. Leaflets 3-5(-7), alternate, glabrous, compound leaves often mixed with unifoliolate ones, elliptic, elliptic-oblong or ovate to lanceolate, (4-)5-15(-19) by (2-)3-6(-7.5) cm, coriaceous; apex long acuminate to acute; base cuncate or rounded; surfaces concolorous, dark brown when dry, glabrous above, glabrescent beneath; nerves (5-)6-8(-9) pairs, sharply arcuating towards apex, rather distinct. Panicles usually axillary, mostly in few fascicles, rarely terminal, rachis (4-)6-12(-20) cm, sparsely hairy; pedicels (2-)3-4 mm long. Sepals 3, elliptic-oblong, c. 3.5 by 2-2.5 mm, minutely hairy inside. Stamens 6; filaments 1-1.5 mm long; anthers linear, 3-3.5 mm long, sometimes hairy along both sides of the connective. Ovary c. 1.5 mm long, whitish hairy; style 1.5-2 mm, slightly recurved at apex. Fruits broadly ellipsoid to ovoid, 3-4 by 2.5-3 cm, mucro sometimes persistent; pericarp rather thick and firm, exocarp glabrescent with age.
