Shrub or tree 2-10(-35) m. Twigs sometimes faintly 2-or 3-angled, (0.5-)l-2 mm in diameter, yellow to brownish, at first with indumentum composed of greyish hairs 0.1 mm long or less, early glabrescent; bark finely striate, not cracking nor flaking. Leaves membranous or chartaceous, of variable shapes, elliptic, obovate, or ovate to lanceolate, 3.5-15(-20) by 1.2-4(-6.5) cm., base cuneate to attenuate, rarely ± rounded, apex acute (-acuminate), sometimes blunt or rounded; greenish or dark brown above; on lower surface greyish, very finely papillate, at first with dense hairs 0.1 mm long, early glabrescent; dots absent; midrib raised above, nerves (6-)8-14(-20) pairs, flat to slightly raised above; venation (very) fine, distinct above or not; petiole 5-20 by 0.7-1.5 mm. Inflorescences: peduncle up to 1 mm, brachyblast simple or forked, up to 5 mm long, in male (2-)5-15-flowered, in female l-3(-5)-flowered; flowers with persistent or partially caducous grey-brown or rusty hairs 0.1-0.3 mm long, perianth 3-(or 4-)lobed, cream to pink inside. Male flowers: pedicel 5-11 mm long, bracteole subpersistent, median, or considerably below or above; buds subglobose or broadly obovoid, apex often depressed, in cross section circular, obtusely or sharply angled (see the note under the type variety), 2.5-5 (-5.5) mm in diameter, cleft 2/3-4/5, lobes 0.5 (-0.8) mm thick; staminal disc flat, slightly concave, or with a small minute mammilla, subtriangular, 1.7-3 mm in diameter; anthers 9-25(-30) (i.e., with 18-50 thecae), completely sessile, 0.2-0.4 mm, closely ap-pressed, erect or horizontal, hidden under the rim of the staminal disc or partially emergent; androphore slender or broad and tapering, 1-2 mm long. Female flowers: pedicel 5-10 mm long, bracteole about the middle; buds ellipsoid to obovoid or subglobose, 4-5 by 2.5-4 mm, cleft 1/2-2/3, lobes 0.7-1 mm thick; ovary ovoid, 1.5-3 mm long; style up to 0.5 mm long, stigma 6-8-lobulate, i.e., 2-lobed and each lobe again 3-4(-5)-lobulate. Fruits 1 or 2 per infructescence, ± ellipsoid, ridged, apex acute, base obtuse, or often up to 5 mm narrowed (beaked) at both ends, 2-5 by 1.5-3 cm, with greyish to rusty hairs 0.1-0.2 mm long, or glabrescent; dry pericarp 1-2.5 mm thick; fruiting pedicel 8-16 mm long.
