Description
Shrub or small tree, up to c. 16 m by 19 cm. Branchlets ferruginous-tomentose when young, glabrescent. Petioles 0.5-1.3 cm. Leaves elliptic or elliptic-ovate to lanceolate, 7.5-18 by 3.5-5.5 cm, herbaceous to thin-coriaceous, glabrous above (sometimes the midrib and the bases of the nerves excepted), more or less densely ferruginous pubescent beneath; base rounded, peltate or not; apex acuminate; nerves 8-11(-14) pairs, faintly curved, distinctly looped and joined. Inflorescences axillary, glomerulous, 0.5-1 cm, few-flowered, densely pilose. Flowers unisexual (dioecious), 4(-5)-merous. Sepals narrowly deltoid to linear, 2-2.5 mm long, inside subglabrous. Petals elliptic, blunt, c. 4 by l.5 mm, outside pilose, inside in the upper half densely tomentose. Stamens in the basal half pilose, in male flowers 3.5 mm long, the tube 0.8 mm, in female flowers 1-2 mm, the tube 0.5 mm; the staminodes glabrous, not rarely absent. Pistil in male flowers moderately reduced to fully absent. Infructescences with a few fruits only.
