'''Keruing''': medium-weight to heavy hardwood, e.g. ''Dipterocarpus baudii'' Korth., ''D. cornutus'' Dyer, ''D. costulatus'' v. Slooten, ''D. crinitus'' Dyer, ''D. verrucosus'' Foxw. ex v. Slooten.
Because of the comparatively wide variation in density of the wood a subdivision into lightweight keruing, medium-weight keruing and heavy keruing is sometimes made.
