Tree 6-20 m. Twigs finely to coarsely striate, 2-4 mm diameter, at first with greyish stellate hairs less than 0.1 mm long, early glabrescent; bark striate, not tending to crack or flake. Leaves membranous or chartaceous, elliptic or oblong, 12-30(-40) by 5.5-12(—19) cm, apex acute-acuminate, base shallowly cordate to broadly rounded; olivaceous above; lower surface greyish, finely papillate or not, at first with inconspicuous, weak, greyish sessile-stellate hairs 0.1 mm long or less, early glabrescent; dots absent; midrib slightly raised above; nerves 15-22 pairs, sunken or ± flat above; venation ± coarse (aréoles 0.5 mm diam. or more), distinct above, faint in older leaves; petiole 10-15 by 2-3 mm. Inflorescences: sessile, brachyblast 2-or 3-furcate, up to 5 mm long; in male 5-10-flowered, female few-flowered; flowers with scale-like hairs less than 0.1 mm long, perianth 3-lobed, reddish (?) inside. Male flowers: pedicel 2.5-7 mm long, bracteole minute, caducous, apical; buds (depressed) globose, 3-3.2 mm diameter, cleft c. 4/5, lobes 0.8 mm thick; staminal disc flat or faintly mammillate, circular, 1.5-2 mm diameter; anthers 8-12, subsessile to just stiped, 0.5-0.6 mm long, horizontal, spaced; androphore 0.6-0.7 mm long. Female flowers: pedicel 3-4 mm long, bracteole caducous, (sub)apical; buds ellipsoid-oblong, ± narrowed in the middle, (4-)5-6 by (2-)2.5-3 mm, cleft c. 1/2, lobes 1 mm thick; ovary long-ovoid, 2-2.5 by 1.5 mm; style slender, 1-1.5 mm long, glabrous, with 2-lobed fleshy stigma, each lobe again shallowly 3-lobulate. Fruits solitary or 2 or 3 together, oblong(-lanceolate), ± fusiform, 7 by 2 cm, base tapering, apex long-tapering or beaked, with grey-brown scale-like hairs less than 0.1 mm, appearing as if subglabrous; dry pericarp 2 mm thick; fruiting pedicel rather stout, 8-10 mm long, with the bracteole scar nearly median.
