Leaves spirally arranged; lamina subcoriaceous, entire, elliptic to obovate, 10-25 by 5-16 cm, apex short-acuminate, base cuneate to obtuse, often mostly almost equal, margin entire, ± revolute; both upper and lower surface (sub)glabrous, but initially with brown uncinate hairs on the margin, sometimes the midrib minutely brown puberulous beneath, smooth; lateral veins 4-6 pairs, some or none forked away from the margin, tertiary venation scalariform, flat; petiole 2.5-5 cm long, 2-3 mm thick, puberulous with brown (retrorse) uncinate hairs, glabrescent, the epidermis persistent; stipules fully amplexicaul, 1-2 cm long, sparsely brown hirtellous or partly puberulous with retrorse uncinate hairs, caducous. Staminate inflorescences axillary, solitary; peduncle 1.5-2.5 cm long, puberulous with brown (retrorse) uncinate hairs, glabrescent; head ellipsoid to ovoid, up to 4 by 2 cm, with annular grooves; perianth tubular, c. 0.8 mm long, the apex 2(-4)-lobed, minutely puberulous; stamen c. 1 mm long, anther c. 0.1 mm long; interfloral bracts (sub)peltate, the apices 0.2-0.4 mm diam., puberulous. Pistillate inflorescences axillary, solitary; peduncle c. 3 cm long, puberulous with brown (retrorse) uncinate hairs; head ellipsoid; perianth tubular, brown puberulous to subhispidulous, the apex convex; stigma simple; flowers intermixed with interfloral bracts, these spathulate to peltate, the apices 2-4 mm diam., brown puberulous.
