It grows in evergreen, lowland rain forests, and is often found on stream banks in small stands. Heartwood Color Brown Yellow Green Yellow to golden-yellow to orange Pale brown White to cream Pale yellow to pale tan, with darker streaks Pale red to pink Brown Dark or gray veining may occasionally be present in the core area. Sapwood Color Grey Same as heartwood Paler than heartwood Not clearly differentiated from the heartwood May be up to 4 inches (10 cm) in width Grain Straight Interlocked Figure Distinct (figure) Other (figure) Even Straight Interlocked Distinct figure Other figure Broad stripe on quartersawn surfaces Occasionally interlocked, but not always Generally straight, but not always Figure shows rays Broad rays produce an attractive 'silver-grain' figure on quartersawn surfaces Texture Coarse Medium Fine Luster Low Lustrous Natural Durability Perishable Non-durable Non-resistant to termites Non durable Sapwood is susceptible to wood staining fungal attack Susceptible to attack from termites (Isoptera) Perishable Susceptible to attack from powder post (Lyctid & Bostrychid) beetles Pinworms (ambrosia beetles) are commonly present Susceptible to attack by termites and pinhole borers Poor weathering properties Odor Has an odor Kiln Schedules UK=E US=T6D2/T3D1 Fr=5 T3D1 Fr=5 Drying (speed) is fast United Kingdom(1)/T6-D2(4/4) T6-D2(4/4) T3-D1(8/4)Us Schedule E(4/4) T3-D1(8/4) US Schedule E (4/4) Kiln Schedule E (4/4) United Kingdom Kiln Drying Rate (in days) is rapid Drying Defects Internal Honeycombing Possible Distortion Moderate end spitting Moderate surface checking Slight twist/warp Severe end splitting Warping is negligible Tendency to split, surface-check and end-checl during drying Severe surface checking No twisting or warping Knots remain sound Extension of existing shakes may also occur Blue-stain is liable to occur during kiln drying Ease of Drying Slowly Easy Shrinkage from Green to 12%MC, Radial-2.5%, Tangential-5.0% Fairly easy Kiln Drying Rate Kiln drying rate (green to 12% mc) is rapid, typically from less than 10 days for a board under 32 mm, to less than 30 days for a board 63 mm and thicker. Tree Identification Bole/stem form is straight Bole/stem form is fluted Bole/stem form is buttressed Bole/stem form is not buttressed Tree Size Tree height is 60-70 m Trunk diameter is 100-150 cm It develops straight boles that are slightly fluted at the base. Product Sources The ITTO reports that the species has the potential to be a source of valuable timber.

Dries flat without splitting Suitable for slicing Diifficult to veneer Steam Bending Fair to Good Results Very poor Poor Poor steam bending qualities Polishing Satisfactory results Polishes and finishes well Staining Very Good to Excellent Results Staining (Characteristic) = coloured water-soluble extract Strength Properties Density (dry weight) = 38-45 lbs/cu. ft. Max. crushing strength = high Modulus of Elasticity (stiffness) = medium Shrinkage, Radial = small Bending strength (MOR) = medium Shrinkage, Tangential = moderate Bending strength (MOR) = high Shearing strength (parallel to grain) = medium Modulus of Elasticity (stiffness) = low Shrinkage, Tangential = small Max. crushing strength = medium
