Asvakarna, Dipterocarpus turbinatus

Asvakarna, is a deciduous tree, usually growing 35 - 50 metres tall, but with reports of specimens up to 60 metres. The straight, cylindrical bole can be up to 150cm in diameter and free of branches for two thirds of the tree's height. The tree is harvested from the wild mainly for the oleo-resin in its trunk. This is used locally and also exported. The tree also yields a timber of low quality, though this is used on a large scale in the manufacture of plywood.
