Young shoots and petioles minutely and sparsely pubescent at first, soon glabrescent, rarely densely or evenly and persistently pubescent.. Buds minutely perulate.. Petioles 2–5 mm. long, glabrous or pubescent; leaf-blade elliptic, elliptic-lanceolate or oblong-lanceolate, 4–15 cm. long, 1.5–6.5 cm. wide, obtusely acuminate, asymmetrically cuneate-rounded, almost entire or only very shallowly toothed, rarely sharply serrate, coriaceous, lateral nerves 7–8 pairs, looped within the margin, tertiary nerves reticulate, all nerves more prominent beneath than above, quite glabrous above and beneath.. Stipules lanceolate, 1.3–1.5 mm. long, sparingly pubescent, soon deciduous.. Flowers fasciculate on bosses on the trunk from ground-level up to the first branches, but not on the branches themselves.. Male flowers: pedicels 1–1.5(–3) cm. long, slender, glabrous; sepals orbicular or suborbicular, adaxially concave, (3–)5(–9) mm. long, (3–)4.5(–9) mm. wide, glabrous, the outer minutely ciliolate, pale yellow or greenish cream; stamens 10–18, in a single peripheral whorl, 5 mm. long, anthers 2 mm. long; disc lobulate around the margin, the lobes partially enveloping the filaments, muricate-alveolate, glabrous.. Female flowers: pedicels (1–)2–3 cm. long, extending to 4–5 cm. in fruit, fairly slender, glabrous; sepals reddish brown, otherwise ± as in the male; disc fleshy, undulate, glabrous; ovary 3-locular, subglobose, 2 mm. long, 3 mm. wide, usually glabrous (pubescent in var. trichogyna); styles 3; stigmas ± sessile, obdeltoid, bifid..
