Leaves membranous or chartaceous; elliptic to lanceolate, (3—)5—18 by 1-5 cm, apex acute-acuminate, base attenuate or cuneate, drying greenish to brown above; lower surface greyish, with sub-persistent, scattered, mainly stellate scale-like hairs of ± equal size, 0.1 mm long or less; dots absent; midrib flat to raised above; nerves 10-21 pairs, slender, sunken or but slightly raised, indistinct above; venation either raised and distinct, or sunken and indistinct; petiole 6-16 by 0.5-2 mm. Inflorescences: peduncle up to 1 mm long, brachyblast simple or 2-or 3-fid, 1—3(—7) mm long; in male (l-)3-10-flowered, female 1-6-flowered; flowers with greyish to rusty hairs 0.1 mm long, sometimes with emergent hairs up to 0.3 mm; perianth 3-lobed, creamy or yellowish inside (always?). Male flowers: pedicel 5-10 mm long, bracteole persistent or caducous, about median to nearly apical; buds subglobose or broadly obovoid, (1.5-)2-3(-4?) mm diameter, cleft 3/4-2/3, lobes 0.5-0.8 mm thick; staminal disc ± flat, circular or subtriangular, 1-2.2 mm diameter; anthers 6-11, just to distinctly stiped, (almost) horizontal, 0.3-0.5 mm long, spaced; androphore 1 mm long. Female flowers: pedicel 3-12 mm long, bracteole about median; buds ellipsoid or obovoid, 3.5-5 mm long, cleft c. 1/2; ovary ovoid, 1.5-2 by 1-1.5 mm, style 0.5 mm long, stigma 2-lobed and each lobe again (2-)3-10-lobulate or serrate. Fruits 1-5 per infructescence, subglobose or obovoid, apex rounded to subacute, base rounded, sometimes ± attenuate, (1.2—)1.5 by 0.7-1 cm, with rusty scale-like hairs 0.1 mm long or less; dry pericarp 1 mm thick; fruiting pedicel 4-20 mm long.
