Dryobalanops oblongifolia

Dryobalanops oblongifolia is a species of plant in the Dipterocarpaceae family. The species name is derived from Latin (oblongus = rather long and folium = leaf) and refers to the shape of the leaf. There are two subspecies:

Dryobalanops oblongifolia Dyer subsp. oblongifolia Dyer (synonyms = Baillonodendron malayanum F.Heim & Dryobalanops abnormis Slooten) is endemic to Borneo. It is found in at least one protected areas (Kubah National Park), but is threatened elsewhere due to habitat loss.[1] It is an emergent tree, up to 60 m tall, found in mixed dipterocarp forest on sandy clay soils.[1]

The second subspecies Dryobalanops oblongifolia Dyer subsp. occidentalis P.S.Ashton (synonyms = Dryobalanops beccariana Ridl. & Dryobalanops ovalifolia Burkill) is found in Sumatra and Peninsular Malaysia. Both are heavy hardwood sold under the trade names of Kapur.
