Tree 25 m. Twigs stout, 5-7 mm diameter, early glabrescent, hairs less than 0.1 mm; older twigs incompletely known, possibly somewhat fissured but not distinctly flaking, with a few lenticels. Leaves (thinly) coriaceous (but very brittle), 21-40 by 6-12 cm, base narrowly rounded, apex acute; upper surface brown, smooth, lower surface slightly paler, glabrous; not papillose; dots present (lens!); midrib slightly raised above, lateral nerves 20-40 per side, at 60-70° to the midrib, flat and faint above, hardly visible below, lines of interarching and venation invisible; petiole 30 by 4-5 mm; leaf bud 10 by 4 mm, hairs appressed, grey-brown, less than 0.1 mm. Inflorescences between the leaves, minutely brown pubescent, late glabrescent, with pedunculate (surface may be fissured) brachyblast; bracts 2-2.5 mm, caducous; in male (van Royen 3498): peduncle 5-15 mm, with transverse lenticels, scar-covered brachyblast to 10 mm, with subumbel of 3-6 flowers, buds of various sizes; female inflorescences (incompletely known, Beccari 7703): peduncle 5 mm long, brachyblast to 10 mm long, ending in a subumbel of 2 or 3(-5) flowers; flowers leathery with hairs 0.1-0.2 mm. Male flowers: pedicel 10-15 by 1.5-2.5 mm, bracteole scar conspicuous, 2-3 mm below the apex; buds ellipsoid-oblong, 9-11 by 4-5 mm (according to Warburg and Sinclair 13-14 by 6-8 mm), cleft c. 1/5, lobes 2-2.5 mm long, 0.5 mm thick. Androecium ± stout, broad-cylindrical, 7 mm long; androphore 2-2.5 by 1.5-2(-2.5) mm, entirely with hairs 0.3-0.5 mm; synandrium 2.5-2.5 by 1.5-2 mm, gradually narrowed into acute sterile apex, 1-1.5 mm, thecae c. 20. Female flowers: pedicel stout, 5-6 mm long, bracteole scar 1-2 mm below the apex; buds ovoid(-oblong), narrowed towards the apex, 9 by 5 mm, lobes 2(-2.5) mm; ovary ovoid-oblong, tapering, 7 by 3.5 mm, hairs 0.5 mm. Fruits (immature, see note 2) broadly fusiform, 3 by 2 cm, hairs mealy, 0.3(-0.5) mm; pericarp hard, 8(-10) mm thick; seeds not seen; fruiting pedicel (immature) 7 by 3 mm.
