Palaquium rostratum is an evergreen tree growing up to 55 metres tall. The straight, cylindrical bole can be 120 - 200cm in diameter with large plank buttresses[
The tree provides an edible fruit and oil, which are gathered from the wild for local use. It also provides a useful timber, which is used locally and also traded under the name 'Nyatoh'.
Southeast Asia - Thailand, Malaysia, Indonesia.
Lowland to montane forest[
]. An emergent tree in undisturbed mixed dipterocarp, keranga, swamp, coastal and sub-montane forests at elevations up to 1,200 metres[
]. In secondary forests usually present as a pre-disturbance remnant[

The tree is found in the wild both in alluvial sites as well as on ridges, mostly on sandy soils, but also on clay and limestone[
]. The fruits are long, green, drupes about 24 - 40mm long[
An oil is obtained from the seeds[
]. It is used for cooking[
The reddish-brown wood is light in weight, durable and easily worked[
]. An attractive timber, it is used for furniture, floors, boards, beams, canoes, house construction and panelling[
We do not have any more specific information on the wood of this species, but it belongs to a group of timbers collectively called 'Nyatoh'[
]. The general description of nyatoh wood is as follows:-
The heartwood is a dark pink to a red-brown; it is clearly demarcated from the 4 - 9cm wide band of lighter-coloured sapwood. The texture is medium; the grain straight or interlocked, sometimes wavy. The wood is light in weight, soft to moderately hard; strong, somewhat durable, being resistant to dry wood borers, moderately resistant to fungi but susceptible to termites. It seasons somewhat slowly, with a high risk of checking and distortion; once dry it is stable in service. There is a very variable content of silica according to the species, but in general the wood has a high blunting effect so stellite-tipped and tungsten-carbide tools are recommended; nailing and screwing are good, but require pre-boring; gluing is correct. The wood has a range of applications, including for high class furniture and cabinet making, solid doors, panelling, joinery, parquet flooring, boat decking, light carpentry, turnery, moulding and veneer[
