General Wood Description
Color
The sapwood is grey-white. The heartwood is dark-brown or red, darkening on exposure, it is clearly demarcated.
Grain
Wavy or slightly interlocked; special care is needed when machining in order to obtain satisfying quality surface.
Texture
Fine texture is reported in this species.
Luster
This wood is commonly of low luster.
Natural Durability
Very durable to decay; without preservative treatment. This species is especially suited for all the uses with risks of permanent or long-lasting humidification. Resistant to termites attack. Heartwood is resistant to Lyctus attacks.
