Tree, 10-20 m, 30-40 cm ø. Branchlets initially densely set with brownish stellate hairs, late glabrescent, dark grey, shallowly fissured; older branchlets lenticellate, glabrous; terminal buds ovoid-globose, densely tomentose. Stipules linear-acute, 2-4 by ¼-½ mm. Leaves thick-coriaceous, ovate-elliptic or ovate-lanceolate, (3-)5-10(-14) by 2-5½ cm; base rounded or cordate, slightly asymmetrical, top sharply acute or ½-2 cm acuminate; margin entire or remotely serrulate in the apical half; beneath densely brownish stellate tomentose or almost glabrous, above glabrous and glossy or dull and with sparse stellate tomentum (especially on the midrib); midrib and nerves impressed above, prominent or flattened beneath; nerves 5-8 pairs, at an angle of 50-60°, parallel, arcuating towards the margin; reticulation fine, more or less areolate, distinct beneath; petiole 1-2½ cm, sulcate, densely tomentose by simple or stellate hairs. Male rachis slender, 5-10 cm, simple or rarely much-branched; bracts ovate-acute, 1-2 by ½ mm, densely stellate-tomentose, glabrescent; ♂ flowers 1-3; perianth densely tomentose by simple or stellate hairs, glabrescent, anthers 1 by ½-1 mm, filaments 1 mm, pistillode replaced by a cluster of woolly, simple hairs.

Young cupule obconical, 0.8-1 cm high, 0.7-1.2 cm ø; lamellae thin, 5-7, the lower ones denticulate, the rest entire, densely stellate-tomentose. Ripe cupule cup-shaped, 0.8-1 cm high, 1.3-1.8 cm ø, base rounded, covering ¼-⅓ part of the fruit.
