Characteristics

Medium-sized, dioecious tree 15-24 m, 8-35 (-50) cm ø; bark pale grey-brown to dark brown, fissured; wood straw-coloured or light brown. Leaves elliptic or oblong-elliptic, rarely narrowly obovate, 5-14 by 3-9 cm, rounded at the apex, narrowed, rounded or subcordate at the base, shallowly crenate, rather fleshy in life, drying thick and with minutely rugulose surface, the costa sometimes dividing the leaf somewhat asymmetrically, subsessile; nerves 10-15 pairs; petiole thick, c. 2 mm; stipules minute, c. 1 mm long; leafless nodes present with sheaths 2-6 mm long bearing lateral leaf-vestiges 0.8-1.5 mm long, rugulose in dry state. Inflorescences terminal, branched and occasionally a simple unbranched one from a lower node. Male 2 cm long, 3-branched at the base, the main branch with side branchlets c. 5 mm long; anthers c. 3 mm long. Female 1.5-4 cm long with 3-5 main branches each with 5-7 rather thick branchlets 1.5—2.5(—3) cm; lower bracts similar to the leaf-vestiges at leafless nodes, the upper again similar but with the lateral projections longer, lanceolate, longitudinally folded, 4.5 mm long; bracteoles supporting flowers deltoid, scarcely 1 mm long; female flowers not seen. Fruits greenish white (presumably becoming dark when ripe?), ovoid, ± congested; exocarp strongly wrinkled in the dry state; endocarp c. 1 mm long (mature?), smooth.
