Dipteraceæ

Dipteraceæ, or DIPTEROCARPACEÆ, an East Indian order of thalamifloral dicotyledons, including about 112 species, of which many are majestic trees, valued alike for timber and balsamic resins (see SAL, COPAL, DAMMAR, &c.). Dipterocarpus turbinatus, the Gurjun tree, and other species, yield a fragrant oily resin, the so-called Gurjun balsam, while that of other species is sometimes called Dammar.
