Heartwood Color Brown Yellow Pink Green Grey Orange Light yellow brown or pale orange brown, eventually aging into deep golden-brown Darkens to a russet color with olive cast Brown - orange Sapwood Color Brown Yellow Color not distinct from heartwood Beige white Grain Even Straight Figure Straight to roey Texture Fine Oily feel Oily appearance Medium Luster Medium Slightly lustrous Natural Durability Durable Moderately durable Highly resistant to decay and wood destroying insects Odor No specific smell or taste Silica Content High Siliceous Likely to have significant impact on machining Drying Defects Distortion Case Hardening Checking Severe surface checking Distortion (twist/warp) is likely Ease of Drying Moderately Difficult to Difficult Thick Stock Requires Care Slowly Fairly Easy Controlled drying conditions will prevent rapid drying and yield best results. Tree Size Bole length is 0-10 m Tree height is 30-40 m Product Sources The ITTO reports that timber is regularly produced from this species, but it is exported in small quantities.

It responds poorly to ordinary tools in machining operations, and specially tipped cutting tools have been recommended.
