Observations
- A medium-sized to fairly large tree of up to 40 m tall, bole tall, branchless for up to 25 m, up to 150 cm in diameter, buttresses blunt, bark surface non-fissured, dark grey to yellowish-grey, flaky, outer bark thin, grey, inner bark pinkish-brown, brittle, sapwood pale ochre; buds lanceolate-falcate, glabrous.
- Leaves broadly elliptical, 8-13 cm × 3.3-7 cm, base cuneate, acumen up to 5 mm long, secondary veins (7-)9-11 pairs, ascending, glabrous, petiole 2-3 cm long, stipules linear-lanceolate, subacute, inside silky tomentose.
