Croixia pseudocuneata (H.J.Lam) Baehni
Palaquium pseudocuneatum is an evergreen tree that can grow up to 43 metres tall. The straight, cylindrical bole can be up to 55cm in diameter[
The tree is harvested from the wild for its wood, which is used locally and also traded under the name 'Nyatoh'.
Palaquium pseudocuneatum has a relatively large range and is also found in National Parks. Whilst there is a projected continuing decline in the extent and quality of habitat and a suspected population decline, the plant is currently classified as 'Least Concern' in the IUCN Red List of Threatened Species(2018)[
Southeast Asia - Malaysia, Brunei, Indonesia; only on the Island of Borneo; Philippines.
An upper canopy tree in undisturbed peat-swamp, keranga, coastal, mixed dipterocarp and sub-montane forests; usually in peat-swamps, but also on dry sandy, clay or limestone sites; at elevations up to 1,000 metres[
|Conservation Status||Least Concern
|Other Uses Rating||
The timber is locally used for house building[
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[
