Tree 10-25 m. Twigs sometimes faintly angled, 3-6 mm diameter, at first with yellowish or rusty, ± scale-like stellate hairs 0.1-0.2 mm long, early glabrescent; bark striate, not tending to crack or flake. Leaves (rigidly) coriaceous, oblong to lanceolate, (15-)20-45 by 3.5-10 cm, base broadly truncate, obtuse, or attenuate, apex obtuse or acute(-acuminate); drying olivaceous to dark brown, often with scattered hair scars above; lower surface early glabrescent or with subpersistent grey-brown hairs 0.1-0.3 mm long, especially near the nerves; dots absent; midrib little raised above; nerves 25-50 pairs, little raised but distinct above; venation raised and distinct; petiole 15-25 by 3-7 mm. Inflorescences: sessile, brachyblast simple or ± warted, 3-5 mm diameter, in male 2-6 (-10)-flowered; flowers with yellowish brown or rusty hairs 0.1 mm long or less; perianth 3-lobed, pale pink inside. Male flowers: pedicel 5-15 mm long, bracteole caducous, about median; buds broadly obovoid to depressed globose, (3.5-)4-7 mm diameter, cleft 3/4-4/5, lobes 0.8-2 mm thick; staminal disc flat or slightly concave, circular or sub-triangular, 2-4 mm diameter; anthers 11-15, half-sessile to nearly stiped, horizontal or half-erect, 0.5-0.6 mm, not or hardly touching; androphore 1-2 mm long, clasped by the swollen base of perianth. Female flowers not seen; stigma (on immature fruits) subsessile, 1-1.5 mm diam., 2-lobed and each lobe again with 4 or 5 laciniations. Fruits 1 or 2 per infructescence, ellipsoid, 3-5 by 1.7-3 cm, sometimes flanged along the line of suture; dry pericarp 2-4 mm thick, with hairs 0.2 mm long; fruiting pedicel 2-10 mm long.
