__NOTOC__
:Protologue: Bull. Jard. Bot. Buitenzorg, sér. 3, 16: 445, f. 6 (1940).
== Vernacular names ==
*Brunei: keruing sindor (Malay), resak kerangas (Iban)
*Indonesia: keruing daun halus (general), awang buah (East Kalimantan), tempudau (South Kalimantan)
*Malaysia: keruing sindor (Sarawak).
== Distribution ==
Eastern coastal Sumatra and Borneo (Kalimantan, Sarawak, Brunei).
== Uses ==
The timber is used as keruing, but is very resinous.
== Observations ==
A medium-sized tree of up to 30 m tall, bole often of poor shape, up to 64 cm in diameter and with low, rounded buttresses, bark surface with corky pustules, pale orange-brown, tending to turn pale greyish-white; buds ovoid, densely pinkish buff pubescent; leaves broadly ovate to elliptical, 7-12 cm × 3-7 cm, base obtuse or broadly cuneate, acumen to 8 mm long, secondary veins 9-12 pairs, lower surface sparsely shortly caducous pubescent on the veins, petiole 1.5-2.5 cm long, sparsely pubescent, stipules linear, acute; stamens about 25; fruit calyx tube narrowly ovoid to ellipsoid, with 5 narrow wings, glabrous, 2 larger fruit calyx lobes up to 7.5 cm × 1.8 cm, 3 shorter ones about 5 mm × 4 mm. ''D. borneensis'' is widespread but owing to its edaphic preferences mainly subcoastal. It occurs in heath forest on podzols or giant podzols below 350 m altitude. The density of the wood is 690-900 kg/m<sup>3</sup>at 15% moisture content.
== Selected sources ==
