Characteristics

Treelet 10-13 m. Twigs 1 mm diameter, early glabrescent, hairs setose, 0.5-1 mm long; older twigs ± smooth; lenticels not apparent. Leaves membranous, ovate-elliptic or elliptic-oblong, 6-12.5 by 2-5 cm, base ± rounded or attenuate, apex acute-acuminate; upper surface grey-green or brown, lower surface greyish brown, early glabrescent or few rather long widely scattered hairs left; not papillose; dots absent; midrib flat or somewhat raised above, lateral nerves 7-10 per side, at 50-80° to the midrib, flat and faint above, rather faint below, lines of interarching and venation indistinct; petiole 6-10 by 1 mm; leaf bud 6-8 by 1 mm, hairs (0.5-)l mm long. Inflorescences between the leaves or below, paniculate; in male: peduncle 5-20 by 0.5-0.8 mm, ending in a simple or forked, densely scar-covered, ± pubescent brachyblast to 9 mm long, with cluster(s) of 2-5 flowers, buds of various sizes; in female (from infructescence): peduncle 9 mm, one-or few-flowered, unbranched; flowers with shaggy hairs (0.3-)0.5 mm. Male flowers: pedicel slender, 3 mm long, bracteole ± ovate, 1(—1.5) mm, persistent, (sub)apical; perianth membranous, inside not warty; buds ellipsoid-oblong, 4-4.2 by 1.5-1.8 mm, apex and base subacute to obtuse, cleft 1/5-1/4, lobes 0.7-1 mm. Androecium slender, 3.8 mm long; androphore 4 by 0.4 mm, with appressed hairs 0.4 mm long; synandrium 1.8 by 0.5 mm, thecae 6, not closely appressed, sterile apex 0.1 mm. Female flowers not seen. Infructescence simple, peduncle slender, 8-10 mm long, proceeding into a 12-14 mm long pedicel of a single fruit. Fruits ± ellipsoid, 2-2.5 by 1-1.3 cm, apex short-apic-ulate, base contracted into pseudostalk up to 5 mm; hairs dull brown, scurfy, less than 0.1 mm, at apex and base longer and shaggy; pericarp thin, 1 mm thick; seeds ellipsoid, 1.5 cm; fruiting pedicel slender, 14 mm long, bracteole scar 3-4 mm below the apex.
