Anisoptera spp. of the family Dipterocarpaceae. Native to Malaysia and Indonesia. There are at least a dozen species in the genus Anisoptera that have mersawa as all or part of one or more of their common names, and I have no idea which of them are represented on this page.
my samples:
both sides of a flat cut sample plank of mersawa / Anisoptera spp.
