Dipterocarpus acutangulus

Dipterocarpus acutangulus is a species of tree in the family Dipterocarpaceae. The species name acutangulus is derived from Latin (angulus = angle, acutus = sharp) and refers to the ribs of the fruit calyx tube. [2] It is native to peninsular Thailand and Malaysia and also Borneo, where it is locally known as keruing merkah or keruing beludu. It is an emergent tree up to 60 m tall. The tree occurs in mixed dipterocarp forests found on sandy and sandy clay soils on coastal hills and inland ridges, up to 1000 m elevation. It occurs in at least one protected area (Kabili-Sepilok Forest Reserve).
