Environment profile: Status has not been officially assessed
Tree size: Trunk diameter is 300-350 cm
Colors: the heart isLight brownand the sapwoodClearly differentiated from the heartwood, Pale yellow.The grain isStriped figure, the textureMedium coarse to coarseand the lusterMedium
Natural durability: Susceptible to insect attack, Very durable
Odor: No specific smell or taste
Drying Defects: Distortion
The material air-seasons rapidly with little degrade. It also kiln dries with only slight checking and twisting. Some discoloration may occur during seasoning due to mold growth
Ease of Drying: Seasons rapidly with little degrade
Tree Identification: Bole/stem form is straight
Comments: Reaction with Metals - The timber tends to develop stains when it comes in contact with iron and iron compounds under moist conditions.

Bending strength (MOR) = very high Shrinkage, Tangential = fairly large Shrinkage, Radial = moderate Max. crushing strength = high Density (dry weight) = 38-45 lbs/cu. ft. Bending strength (MOR) = high Shrinkage, Volumetric = fairly large Shrinkage, Tangential = moderate Shrinkage, Tangential = large Shrinkage, Radial = small Shrinkage, Radial = fairly large Shearing strength (parallel to grain) = high Modulus of Elasticity (stiffness) = high Bending strength (MOR) = medium
