Tree 5-25 m, 15-70 cm ø; buttresses and stilt-roots sometimes present; bark greyish brown, scaly, lenticellate. Branchlets initially densely yellowish brown to fulvous or rufous tomentose by long, erect simple hairs and adpressed stellate hairs, later subglabrous, greyish to blackish brown, sparsely lenticellate; terminal buds ovoid, 3-5 by 2-3 mm, scales narrowly ovate to linear. Stipules ovate to lanceolate, 5-6 by 2-3 mm. Leaves char-taceous to coriaceous, (9-)14-20(-23) by (3-)4-6 (-8) cm (index (2.6-)3-3½(-4)), broadest about the middle; surfaces discolorous, above glabrous, except the midrib and nerves, dull greyish green, rarely glossy, underneath dull chocolate-brown, rarely glossy, densely yellowish brown to rufous hairy by erect simple hairs and adpressed stellate hairs, glabrescent except the midrib and nerves; base attenuate-acute to rounded-acute, occasionally asymmetrical, top bluntly acute with emarginate tip to sharply or bluntly 1-2 cm acuminate; midrib strongly prominent beneath, slightly so above; nerves (9-)10(-14) pairs, strongly prominent beneath, impressed above, subparallel, at an angle of 45-60°, arcuating and anastomosing near the margin; reticulation lax, subscalariform, distinct beneath; petiole densely fulvous to rufous stellate hairy, (3-)5-10(-12) mm, 1-3 mm ø, terete or adaxially flat. Inflorescence male, androgynous or mixed, densely fulvous to rufous stellate hairy; bracts and bracteoles ovate, 1-2 by ½-1 mm. Male rachis 10-15 cm, 1-1½ mm ø; ♂ flowers solitary, filaments 3-4 mm, anthers 0.3-0.35 mm long, pistillode subglobose, 1-1½ mm ø. Androgynous or mixed rachis 10-20 cm, 1½-2 mm ø; female flowers solitary, staminodes rather well-developed but not exceeding the perianth, styles 3, terete, 2-3 mm, strongly recurved. Ripe cupule subsessile, cup-shaped, 1⅓-2 cm long, 2-2⅔ cm ø; rim thin, erect and entire or undulate and recurved, covering ¼-⅓ part of the fruit; wall woody, thin, inside densely fulvous to rufous tomentose by adpressed stellate hairs, outside densely fulvous to rufous-tomentose by adpressed stellate hairs; scales minute, adpressed, imbricate or occasionally in more or less concentric rows. Ripe fruit ovoid-globose to cylindrical, 2-3 cm long, 1½-2 cm ø, densely greyish brown tomentose by adpressed simple hairs, subglabrescent, top rounded-acute to rotundate-apiculate, base truncate, scar deeply concave to flat, ½-1 cm ø; wall woody, 1 mm thick, for the greater part free from the cupule.

Forests, at low altitude, sometimes also in peat-swamp or heath forest, on sandy clayey to ultra-basic soil; usually along stream. Fl. fr. throughout the year.
