Tree 10-20 m. Twigs 1.5-2.5 mm diameter, at first with stellate hairs 0.1-0.2 mm long, early glabrescent; bark striate, not cracking or flaking. Leaves membranous or chartaceous, elliptic-oblong to oblong-lanceolate, 13-26 by 4-8 cm, apex up to 1.5 cm acute-acuminate, base rounded to attenuate; greenish to brown above, the midrib late glabrescent; lower surface greyish, at first with sparse to dense greyish hairs of mixed size (0.1-0.2 mm long, and coarser stellate dendroid hairs 0.3-0.5 mm long), late glabrescent, the longer hairs earlier shed and leaving hair scars (lens!); dots absent; midrib and nerves (20-25 pairs) slightly raised above; venation fine (aréoles 0.5 mm diameter or less), distinct above; petiole 8-13 by 1.5-2.5 mm. Inflorescences: sessile or pedunculate to 1 mm, brachyblast simple or 2-or 3-fid, up to 5 mm long; in male 5-10-flowered, female 1-6-flowered, flowers with persistent yellowish brown hairs 0.1 mm long or less; perianth 3-lobed, greenish or yellowish inside. Male flowers: pedicel (3-) 5-9 mm long, bracteole caducous, 1-3 mm below the apex; buds depressed globose to broadly obovoid, 3-4 by (3-)3.5-5 mm, cleft c. 4/5, lobes 1 mm thick; staminal disc flat to faintly convex, subcircular, 2-2.5(-3) mm diameter; anthers 10-15, ± stiped, more or less horizontal, 0.4-0.6 mm long, spaced, the connective broad above, thecae opening downwards; androphore 1.2-1.5 mm long. Female flowers: pedicel 1.5-5 mm long, bracteole caducous, above median; buds (depressed) obovoid-oblong, 4—6 by 2.5-5 mm, cleft over 1/2, lobes 1-1.5 mm thick; ovary ovoid, 3 by 2 mm, stigma ± sessile, 2-lobed, each lobe suberect, and again 2-4-lobulate. Fruits 1-5 per infructescence, broadly ellipsoid, more or less ridged, base rounded, apex subacute, 2-2.7 by 1.5-2 cm, with dense rusty hairs 0.1-0.2 mm long; dry pericarp 1-1.5 mm thick; fruiting pedicel 2-5 mm long.
