Tree (5-) 10-40 m. Twigs 5-10 mm diameter, glabrescent, hairs villose, (1—)2—3 mm long; older twigs brown or blackish, coarsely longitudinally cracking and flaking; lenticels absent. Leaves chartaceous or thinly coriaceous, (elliptic-)oblong, (15-)20-40 by 6-13 cm, base acute or narrowly rounded, apex acute(-acuminate); upper surface olivaceous or brown, lower surface late glabrescent or hairs persistent, dense, grey or cinnamon, scale-like (dendroid), 0.1-0.2 mm, mixed with widely spaced unbranched uniseriate emergent hairs 1-3 mm; not obviously papillose; dots absent; midrib ± raised above, lateral nerves 20-25 per side, at 45-60° to the midrib, sunken, lines of interarching and venation distinct; petiole (12-)20-25 by 3.5-5 mm, late glabrescent; leaf bud 7-12 by 4-6 mm, hairs conspicuous, (1—)2—3 mm. Inflorescences between the leaves or below, of the Knema-type: a sessile scar-covered brachyblast, pubescent; bracts ovoid or rounded, 3-4 mm, caducous; in male: simple or 2-4-furcate, 5-13 by 5-10 mm, terminally with 1-3 subsessile flowers, buds subequal in size; in female: similar, shorter, with 1 or 2 flowers ± hidden in coarse indumentum; flowers coriaceous, with villose hairs 1-2 mm long. Male flowers: pedicel rather thick, 3-4(-5) mm long, bracteole broadly rounded, 3-4 mm, late caducous; buds ovoid(-ellipsoid), 6-8 by 4-5(-6) mm, apex narrowly rounded, cleft c. 2/3, lobes 1 mm thick. Androecium slender, 4-5 mm long; androphore (0.5-)l by 0.4-0.5 mm, at base with a collar of pale hairs 1 mm; synandrium 3.5-4.5 by 0.6 mm, thecae c. 12, sterile apex ± blunt (0.2-)0.3-0.5 mm long. Female flowers: pedicel 1 mm long, bracteole broadly rounded, 4-5 mm, ± caducous; buds ovoid, 8(-10) by (5-)6-8 mm, cleft c. 2/3; ovary (broadly) ovoid, 5-6 by 4 mm, hairs 1-1.5 mm; stigma 1(—1.5) mm. Fruits 1 or 2 per infructescence, subsessile, broadly (ovoid-)ellipsoid, apex rounded or narrowed with somewhat uncinate apex, 4-6(-8) by 2.5-4(-4.5) cm, hairs dense, pale brown or rust-coloured, somewhat hispid, 2-3(-4) mm; pericarp 3-6(-8) mm thick; seeds broad-ellipsoid, 3-5 cm, aril coarsely laciniate, the laciniae finely divided at the apex; fruiting pedicel up to 5 mm long.
