Tree 20-40 m. Twigs 2-4 mm diameter, glabrescent, hairs 0.5(-l) mm long; older twigs somewhat longitudinally cracking, probably later on ± flaking; lenticels absent. Leaves thinly chartaceous, elliptic-or obovate-oblong, 15-21 by 4.5-10 cm, base cuneate, rounded, or subcordate, apex acute-acuminate; upper surface olivaceous(-brown), lower surface yellowish brown, hairs persistent, dense, pale, floccose, interwoven, 0.1-0.2 mm with numerous emergent brown or yellowish hairs of varying length, up to 1 mm; not papillose; dots absent; midrib slightly raised above, with some indumentum remaining in younger leaves, lateral nerves 13-23 per side, at 60-80° to the midrib, lines of inter-arching distinct, venation distinct or faint; petiole late glabrescent, 12-20 by 2.5-3.5 mm; leaf bud 10-15 by 2-3 mm, hairs 0.5-1 mm long. Inflorescences (from infructes-cences) of the Knema-type: in female a sessile, wart-like brachyblast, few-flowered, between the leaves (or below), or rarely a few in a lateral short-shoot. Male and female flowers not known. Infructescences very short. Fruits: subsessile, single or 2-4 in a cluster, acorn-shaped, about as broad as long or broader than long, ± broadly ovoid, 1.3-2.3 by 1.8-2.7 cm, apex (broadly) rounded with short pointed tip, base broadly truncate, flat, or depressed, hairs dark (yellow-)brown, floccose, 0.5-1 mm long; pericarp 2(-3) mm thick; seeds broadly ellipsoid, broadly rounded at both ends, 1.5 cm; fruiting pedicel slender, 5-10 by 2-3 mm, pubescent, bracteole scar apical.
