Shrub or slender treelet, 2-10 m. Twigs 1-2 mm diameter, with rusty hairs 0.1 (-0.2) mm, late glabrescent; bark finely striate, not cracked nor flaking; lenticels absent or few and inconspicuous. Leaves membranous or thinly chartaceous, oblong to lanceolate, 7-15 by 1.5-4 cm, base acute or attenuate, apex acute-acuminate to long-tapering; blade drying blackish brown, glabrous above, beneath glabrescent (with few minute hairs remaining on midrib); dots absent; midrib very slender, slightly raised above; nerves 12-25 pairs, indistinct, flat or slightly raised above, lines of interarching distinct or indistinct; venation indistinct; petiole 7-12 by (0.5-)l mm, glabrescent; leaf bud 5-7(-10) by 0.5-1 mm, with dense minute rusty hairs 0.1 mm. Inflorescences among the leaves, small, twice branched (lowest branch 2-5 mm from the base), with hairs 0.1 mm or less; bracts ellipsoid, 0.5-1 mm long, caducous; in male: 2 by 2 cm, few-branched, few-flowered; in female: 1-1.5 cm long, not or somewhat branched, 1-3-flowered; flowers solitary or up to 3 together, perianth 2-lobed, thinly with stellate-dendroid hairs 0.1-0.2 mm long, pedicel thinly pubescent, not articulated. Male flowers: pedicel 3-3.5 mm long; buds slightly flattened, subglobose or broadly ellipsoid or obovoid, 2.2-2.4 mm diameter; cleft c. 1/8, perianth 0.7-0.8 mm thick, the lobes at apex 0.2 mm thick; androecium club-shaped, apex subacute to broadly rounded, 1.7-1.8 by 0.6-0.7 mm (Plate 1: 19); thecae 8, apical, mutually appressed, 0.4 mm long, consolidated with the androphore, apex slightly free or not; androphore in the lower 2/3 with dense minute pale brown hairs less than 0.1 mm, the apical part coarsely irregularly warted or wrin-kled-bullate, glabrous; column not hollow at apex. Female flowers: pedicel 2-2.5 mm long; buds subglobose, 1.8 mm diameter, lobes 2, cleft c. 1/8; ovary ellipsoid-ovoid, 1.5 by l(-l.l) mm, densely minutely pubescent; stigma minute, of two suberect lobes 0.1-0.2 mm. Fruits l(-3) per infructescence, ovoid-ellipsoid, including the 2-3 mm long rostrum 1.6-1.7 by 0.9-1 cm, base contracted into pseudostalk 4-5 mm; all thinly with pale brown stellate hairs 0.1 mm or less, drying blackish, without lenticels; pericarp 0.5(-l) mm thick; fruiting pedicel slender, slightly broadened to the apex or not, 8-12 mm long; perianth not persistent.
