APITONG

Dipterocarpus spp.

Dipterocarpus spp. of the family Dipterocarpaceae, the dipterocarp family. The list of species that use apitong as all or part of one or more of their common names is almost a subset of those that use keruing. There are two species that only use apitong, over a dozen that use both, and over 3 dozen that use only keruing. The full list is at:

apitong and keruing species names


It is not clear to me that any rigor is used by vendors in applying common names to species, and I cannot find sufficient information to distinguish among them and so I lump them all together here.

Despite having several formal samples, I am not really familiar with this wood, having never had anything BUT small sample pieces and thus having never worked with it. Paul van Rijckevorsel tells me this is a rough and tough wood from SE Asia (he was speaking of Dipterocarpus spp. and specifically the common name keruing).

I have it anecdotally that oleoresins in the wood make gluing somewhat difficult and the presence of silicates in the wood make it tough on cutting edges.

both sides of a sample plank of a piece of wood from a crate, and strongly believed to be Dipterocarpus spp., but this may or may not be wood that uses the common name apitong. HUGE enlargements are present. This sample was loaned to me by David Clark whom I thank for this and other contributions to the site.
