Tree 10-30 m. Twigs 4-8 mm diameter, glabrescent, hairs 0.1(-0.2) mm or less; older twigs not cracking nor flaking; finely lenticellate. Leaves chartaceous or coriaceous, (elliptic-)oblong, (22-)25-40 by 5-15 cm, base (short-cuneate or) broadly rounded, apex acute-acuminate; upper surface olivaceous or brown, lower surface cinnamon, hairs interwoven, scale-like, 0.1 mm; not papillose; dots absent; midrib flat above, lateral nerves 20-25(-30) per side, at (60-)70-80° to the midrib, lines of interarching and venation indistinct; petiole 20-35 by 4-6 mm; leaf bud 20-30 by 3-4 mm, hairs 0.1 mm or less. Inflorescences between the lower leaves, or below; of the Knema-type: a ± woody scar-covered simple (not forked) brachyblast to 5 mm long, sessile or to 5 mm pedunculate, glabrescent; bracts 2-3 mm long, caducous; in male: with a cluster of 2-7 flowers, buds of variable sizes; in female: l-2(-4)-flowered; flowers with flocculose appressed dense hairs 0.1-0.2(-0.3) mm. Male flowers (LAE 51941): hard leathery, stout, pedicel 10-12 by 2-3 mm, bracteole ± boat-shaped, 6-7 mm long, caducous; buds (almost mature) ± ellipsoid-obovoid, 8 by 5 mm, cleft c. 1/4, the lobes 1 mm thick. Androecium broad, ± fusiform, 6 mm long; androphore 1 by 1 mm, almost glabrous (hairs scattered, pale, less than 0.1 mm); synandrium 5 by 1.5(-2) mm, apex acute, thecae c. 20, sterile apex 0.1 mm or absent. Female flowers (NGF 38940, slightly immature): pedicel 5 by 4 mm, bracteole broadly ovate, 4 by 5 mm; buds subglobose, 5 mm; ovary not seen. Fruit solitary, subglobose or broadly ovoid(-ellipsoid), 7-10 by 6-8 cm, apex rounded or rather acute, hairs dense, mealy, yellow-brown or rust-coloured; pericarp 10-20 mm thick (with thin woody endocarp 0.1-0.2 mm); seeds broadly ovoid(-subglobose), 3.5-5 cm, aril-lobes reaching only to 1/5-1/3 of the seed; fruiting pedicel stout, 15-20 by 6-10 mm, tomentose, bracteole scar at c. 1/3 below the apex.
