- A medium-sized tree, bole straight, up to 70 cm in diameter, with small thin buttresses and stilt roots, exuding a white dammar, bark surface smooth, hoop-marked, pale grey-brown, inner bark pale brown to cream at the cambium, sapwood yellow, hard, heartwood dark brown; young twigs and buds waxy glaucescent.
- Leaves ovate, 5-8 cm × 2-4.5 cm, thin leathery, base cuneate, frequently subequal, acumen slender, up to 1.5 cm long, margin not revolute, venation dryobalanoid, midrib slightly raised above, secondary veins about 8 pairs, indistinct.

H. latifolia is locally frequent in mixed dipterocarp forest on low-lying land. The density of the wood is 625-930 kg/m3 at 15% moisture content.
