Characteristics: Grain variable, straight to roey; texture fine to medium, uniform; no distinctive odor or taste. Moderately difficult to season. Air-dries fast to moderate rate. Laboratory tests indicate the wood to be very durable in resistance to both white and brown rot organisms. These results substantiate the reputed high durability of this species.
Weight: Basic specific gravity (ovendry weight/green volume) averages 0.84 for timber from Honduras and Venezuela; material from Brazil and Colombia averages 0.75. Average air-dry density is about 60 pcf from these four sources.
