Heartwood Color Brown Red Pink Green/grey Yellow Purple Black Orange Pale brown Yellow to golden-yellow to orange Greenish to greyish Yellow/Brown Reddish brown Brown The wood occasionally has an olive tinge and stripes. Sapwood Color Yellow White Green/Grey Brown Same as heartwood Color not distinct from heartwood Grain Straight Closed Even Wavy Straight Wavy Texture Coarse Medium Fine Fine Coarse Medium coarse to coarse Fine to medium Even textured Luster Low Dull Lustrous Natural Durability Perishable Susceptible to insect attack Non-durable Moderately durable Durable Resistant to marine borers Very durable Non-resistant to termites Non-resistant to powder post beetles Durable Susceptible to attack from termites (Isoptera) Susceptible to attack from powder post (Lyctid & Bostrychid) beetles Resistant to attack from termites (Isoptera) Perishable Non durable The timber is immune to attack by termites. Logs should be extracted rapidly from the forest after felling to avoid losses from splitting and attack by insects and fungi. Wood surfaces should be protected against effects of the weather if the timber is to be used in exterior applications. Weathering Good Odor Has an odor No specific smell or taste Silica Content High Kiln Schedules Kiln Drying Rate (in days) is rapid Drying (speed) is fast Drying Defects Splitting Checking Distortion Slight surface checking Ease of Drying Moderately Difficult to Difficult Fairly Easy Slowly Rapidly Seasons well with little or no degrade Easy Kiln Drying Rate Naturally dries slowly Naturally dries quickly Rapid (<10 days for boards < 32 mm, to <30 days for boards >= 63 mm) Tree Identification Bole/stem form is not buttressed Bole/stem form is straight Bole/stem form is cylindrical Tree Size Trunk diameter is 100-150 cm Tree height is 20-30 m Tree height is 30-40 m Bole length is 10-20 m Trunk diameter is 150-200 cm Trunk diameter is 24 to 36 inches (60 to 90 cm) at maturity.

Shrinkage, Tangential = fairly large Max. crushing strength = high Shrinkage, Volumetric = fairly large Shrinkage, Tangential = large Density (dry weight) = 38-45 lbs/cu. ft. Bending strength (MOR) = high Shrinkage, Radial = small Shrinkage, Radial = fairly large Modulus of Elasticity (stiffness) = low Bending strength (MOR) = medium Shrinkage, Radial = moderate Shrinkage, Radial = large Modulus of Elasticity (stiffness) = high Hardness (side grain) = medium Work to Maximum Load = very low Shrinkage, Volumetric = moderate Shrinkage, Tangential = moderate Shearing strength (parallel to grain) = very low Shearing strength (parallel to grain) = low Modulus of Elasticity (stiffness) = very low Max. crushing strength = very high Hardness (side grain) = soft Hardness (side grain) = hard Bending strength in the air-dry condition (about 12 percent moisture content) is very high Compression strength parallel to grain, or maximum crushing strength, is very high - higher than in Teak or Hard maple.
