Tree 8-17 m. Twigs 3.5-5 mm diameter, late glabrescent, hairs dark rusty to reddish brown, 1-1.5 mm long; bark coarsely striate, later on ± longitudinally cracking, not flaking; lenticels indistinct. Leaves chartaceous, sometimes slightly bullate, elliptic to oblong, 10-23 by 5-10(-12) cm, base nearly rounded to subattenuate, apex (acute-)acu-minate; upper surface drying olivaceous-brown, glabrous except for the nerves, lower surface with dense to sparse, rather harsh hairs of variable size (ranging from sessile-stellate, 0.3 mm, to short-armed dendroid emerging hairs up to 1.5 mm long); dots absent; midrib ± raised above, late glabrescent; nerves 11-16 pairs, raised, pubescent or late glabrescent, lines of interarching distinct, regular; venation lax, sunken, distinct or not; petiole 10-16 by 3-4.5 mm, pubescent; leaf bud 15-20 by 3-5 mm with hairs 1-1.5 mm. Inflorescences with dense woolly-shaggy hairs 2-3 mm long; in male: many-flowered, 3 or 4 times branched, 8-12 by 5-7 cm, peduncle 1.5-3 cm; in female: few-flowered, 3 cm long; bracts densely shaggy pubescent, oblong-triangular to lanceolate, 3-8 mm long; flowers in male rather few-flowered in loose clusters, glabrous, perianth 3-or 4-lobed, pedicel indistinctly articulated. Male flowers: pedicel rather stout, 0.5-1 by 0.5 mm; buds subglobose, 2 by 2.3 mm, rather firm, cleft nearly 1/2, lobes 0.2(-0.3) mm thick; androecium globose, 1.2 mm diameter (Plate 2: 58); thecae c. 30 (closely appressed), completely sessile, incurved towards apex; column broad, with small apical hollow to c. 1/5; androphore slender, 0.2 mm long. Female flowers not known. Fruits 2-4 per infructescence, broadly ovoid-ellipsoid, 2-2.2 by 1.5-1.6 cm, glabrescent, with remnants of minute hairs 0.1 mm at the base, without distinct lenticels or tubercles, pericarp 2 mm thick; fruiting pedicel 1-3 mm long; perianth not persistent.
