Trees up to 30 m tall, bole 18 m by 75 cm diameter. Twigs densely and shortly strigose-hirsute, glabrescent. Leaves with petiole 2.5-7 cm, internodes of rachis 1-4 cm. Leaflets ovate or elliptic, 5-14 by 2-6 cm, acute to obtuse, slightly acuminate at apex, obtuse and slightly decurrent at base, with entire margin, (8-)10-15 nerves on each side of midrib, leaf variously strigose or strigose-hirsute, glabrescent. Stipules obovate or suborbicular, strongly unequal-sided, 8-12 by 7-10 mm, often long-persistent. Inflorescence usually false terminal or axillary, occasionally terminal, often 2 partial inflorescences developing serially in an axil and then the upper one usually about twice as strong as the lower one, up to 25 by 15 cm; branches sparsely short hirsute at base to densely so in ultimate branchlets. Flowers with densely stellate-hirsute pedicel to 2 mm long above articulation, 0.5 mm thick, sharply separated from calyx. Sepals ovate or broad-ovate, 2.8-4 by 1.2-3.3 mm, densely and shortly stellate-hirsute beneath, hirsute above. Petals 1.2-2.6 by 0.6-1.7 mm, glabrous, the glands about half the size of the anthers. Stamens with filaments 1 by 2.4 mm long and anthers oval, rounded to retuse at apex and base, 0.3-0.4 by 0.3-0.5 by 0.2-0.3 mm. Disc 0.4-0.6 mm tall, 0.3-0.8 mm thick, glabrous. Ovary ovoid, 0.8-1.2 by 0.8-1 mm, shortly hirsute, each cell with 2 ovules; styles 0.4-0.5 mm, stigmas club-shaped. Fruit with reddish obovate wings coherent along central axis for 14-16 mm; wings at maturity 16-18 by 6 mm, rounded at apex, with entire slightly undulate margin and numerous groups of short stellate hairs.
