Engelhardia roxburghiana

Wall.

Juglandaceae


The generic name of this plant is often spelled Engelhardtia. The original spelling, when the name was first published by Blume in 1825 - 26 was Engelhardia, although this was later corrected to Engelhardtia by Blume in 1829. There still seems to be disagreement over which version of the name is correct, but at present we are following GRIN and Tropicos, who both use the original spelling[

Engelhardtia roxburghiana is a large tree species native to China and Southeast Asia. The deforestation within these ranges is a potential threat to the species but this has not been confirmed and is not identified here as a major threat. The species has a wide native range and an estimated extent of occurrence that exceeds the criteria for a threatened category. Due to this population is assumed to be large. The plant is classified as 'Least Concern' in the IUCN Red List of Threatened Species(2013)[

]. The following is a general description of dungun paya wood:-
The heartwood is grey-brown with a core that has a dark streaky colour; it merges gradually into the pale grey-brown sapwood. The texture is moderately coarse and even; the grain is straight, shallowly interlocked or sometimes wavy. The wood is soft to moderately hard, not very durable. It is easy to work but, being a fairly light timber it should not be used in situations where excessive strength and impact forces are required. Uses of the timber include veneer and plywood, turnery, moulding, tool handle for non-impact purposes, domestic flooring and general utility furniture. The corewood is decorative and it may be used for small ornamental items[
