Plantations Available?
Often planted near villages.
Wood Identification
Anatomic Description Of Wood
Vessels per mm2 less than 6 (rare). Tyloses common. Tangential diameter of vessel lumina 200 micras or more (large). Intervessel pits medium, 7 to 10 micras. Axial parenchyma apparent with the naked eye. Axial parenchyma in thick bands. Prismatic crystals in non-chambered axial parenchyma cells. Occasionally larger rays width 0. 1 mm or more and 2 mm or more in height. Heterogeneous rays and/or multiseriate heterogeneous rays. Prismatic crystals in the ray cells. Sheath cells.

General Wood Description
Color
The heartwood is from pale golden brown to brown, occasionally pinkish brown, it is sometimes not clearly demarcated. The silver figure is medium.
Grain
Straight or slightly interlocked, sometimes with an influence on further processing operations.
Texture
The wood is reported to have a coarse texture.
Luster
The wood is described as moderate in luster.
Natural Durability
Durable to decay; this species can be utilized without preservative treatment for exterior joinery or similar uses. Resistant to termites attack. Heartwood is resistant to Lyctus attacks.
Natural durability index (1= Very high durability, 7=Vey low durability)

Drying Defects
Ease of Drying: Giam timber air dries slowly, often with slight end and sueface cheeks, and splits. Drying Defects: Boards of 15mm thick take about 6 months to air-dry. Kiln Schedules: kiln-drying characternstics have not been assessed but in Malaysia kiln schedule B is recommended.
