Tree 20-30 m. Twigs 2.5-6 mm diameter, late glabrescent, hairs red-brown, coarse, ± erect, 1(—1.5) mm; older twigs dark grey-brown, not cracking; not or inconspicuously lenticellate. Leaves chartaceous or subcoriaceous, ovate-oblong or oblong-lanceolate, 14-33 by 5-12 cm, base cuneate, rounded, or subcordate, apex acute(-acuminate); upper surface olivaceous-brown, lower surface greyish (brown), hairs (especially on the veins) persistent, conspicuous, spaced, 0.1-1.5 mm, with view on papillose lower leaf surface; dots absent; midrib slightly raised above, lateral nerves 20-25(-30) per side, at 60-90° to the midrib, ± sunken above, lines of interarching distinct, venation coarsely netted, sunken above and rendering the leaf bullate; petiole pubescent or late glabrescent, 10-17 by 3-5 mm; leaf bud 10-15 by 4-5 mm, hairs dense, ± rough, rust-coloured, 1-1.5 mm long. Inflorescences between the leaves or below, of the Knema-typt, sessile or pedunculate; in male a to 6 (by 4) mm pedunculate, ± woody, scar-covered brachyblast, simple or bifid, to 1 cm long; flowers in a loose cluster of (2-)4-6; buds of almost equal size; female inflorescence not seen, presumably 1-3-flowered only. Inflorescence and flowers with persistent rough dense rusty hairs 1-1.5 mm; bracts 2 mm, late caducous. Male flowers: stout, pedicel 10-14 by 2-2.5 mm, bracteole broadly rounded, 1 mm long, (late) caducous; buds (ovoid-)oblong or (long-)fusiform, 14—16(—17) by 5-6 mm, apex subacute, cleft 1/8-1/10, lobes leathery, 1.5(-2) mm long, 0.5-0.6 mm thick. Androecium 12-14 mm; androphore 3-4 by (1.5-)2 mm, in the lower half with stiff rufous hairs, 1-1.5 mm; synandrium 7-8 by 1.5-2 mm, thecae c. 20, sterile apex broad or narrow, conical, subacute, 2 mm long. Female flowers (Markgraf, Sinclair, Foreman, I.e.): pedicel 3-8 by 2 mm; buds broadly ovoid, 10 by 5-7 mm, cleft 1/4; ovary nearly as long as the perianth, ovoid-conical, densely setose, stigma substipitate. Fruits single, (ellipsoid-)oblong, 6-7 by 3.5-4 cm, apex narrowed, (sub)acute or shortly beaked, base ± narrowed, hairs dense, rust-coloured, 1-1.5 mm long; pericarp 4-5 mm thick; seeds ellipsoid-oblong, 2.5-3.5 cm, dark brown; fruiting pedicel stout, 10-12 by 5-6 mm, late glabrescent, bracteole scar ± apical.
