| BRIEF DESCRIPTION A slow growing medium sized to tall tree reaching a height of 25-40 m, bole branchless for up to 20 m, with a girth of 2.5-3.5 m and no buttresses. USES The timber is used for medium to heavy constructions but it is not very durable in contact with the ground. When treated with a preservative the timber can also be used outdoors. Because of its resinous nature it is less suitable for flooring and woodwork exposed to the sun, or to be painted. It is used for veneer, plywwod, paper pulp and charcoal. An oleo-resin can be extracted and used as a coat for waterproofing paper, as a varnish for boats, walls and furniture. The oleo-resin and also the bark of the tree have medicinal properties. GROWING PERIOD Perennial. COMMON NAMES Dulia garjan, Keruing bukit, Kanyin in, Kanyin po, Kanyin-ywet-the, Chhe: ti:el bangku:ey, Chhe: ti:el ni:eng daeng, Nha:ng de:ng, Yang-pai, Yang-khao, Yang-kabueang. FURTHER INF Dulia garjan occurs in Bangladesh, Myanmar and on the Andaman Islands. It is found on flat land as well as on undulating country, slopes and hill tops at elevations up to 1200 m. The tree requires shade in youth. Wood production may be 20-40 m3/ha/year. |
