<big>''[[Shorea materialis]]'' Ridley</big>
__NOTOC__
:Protologue: Agric. Bull. Straits Fed. Malay States 9: 183 (1910).
== Vernacular names ==
*Brunei: selangan batu pasir
*Malaysia: balau pasir, balau betul (Peninsular), balau laut (Sarawak).
== Distribution ==
Peninsular Malaysia, north-western Borneo and possibly eastern Sumatra.
== Uses ==
The timber is used as balau. Small amounts of dammar of fairly good quality are obtained from the tree.
== Observations ==
A medium-sized to large tree up to 45 m tall with low-branching bole up to 110 cm in diameter and prominent buttresses up to 2 m high; leaves broadly ovate, falcate with a subequal base, 8-15 cm × 3.5-8.5 cm, with 9-12 pairs of slender secondary veins prominent beneath; petals narrow, stamens c. 30, appendages setose; fruit calyx lobes unequal, larger three up to 9 cm × 3 cm. ''S. materialis'' occurs locally semi-gregarious and has become rare in Peninsular Malaysia as a result of logging. It occurs on giant podzols and sandstone cuestas in heath forest up to 800 m altitude. The density of the wood is 835-1040 kg/m<sup>3</sup>at 15% moisture content.
== Selected sources ==
30, 89, 258, 318, 677, 748.
