Studies on the Wood Properties of Lesser-Known Species Grown in Indonesia (Ⅳ): The Fundamental Wood Properties of Tamiang, Bangelem and Kamasulan

This study was carried out to investigate the wood properties for development the proper uses of lesser-known tree species. The tested species are Tamiang(Hydnocalpus woodiI), Bangelem (Strombosia zeylanica) and Kamasulan(Anisophyllea ferruginea) grown in Indonesia. Fundamental wood properties such as anatomical, physical and chemical properties and characteristics related to wood processing were examined. The results are summarized as follows: These species are diffuse porous, interlocked grained and coarse textured wood. Exceptionally, texture of Tamiang is fine. The heartwoods of these species are not distinguished dearly to the sapwoods. These species have high specific gravity, high shrinkage, and excellent strength properties. However, Tamiang has moderate specific gravity. Sawing characteristics are poor for these species except Tamiang. Sawing characteristics is moderate for Tamiang. Drying characteristics are moderate for Tamiang and Bangelem, and poor for Kamasulan. The surfacing characteristics by planer are moderate for all these species. Bending property and durability are poor. Ash content is low in Bangelem.
