M. pendula occurs in the drier forests of Burma. Heartwood Color Red Brown Pink White Dark brown Brown Purplish brown - dark Purple Black Attractive mottled figure on tangential surfaces Alternating bands of light and dark tissue Sapwood Color Well defined White to yellow White to pale brown Grain Figure Distinct (figure) Mottle Interlocked Straight Even Very fine Distinct figure Mottled or streaked figure sometimes Straight Interlocked Straight to moderately interlocked Figure occurrence is very fine and distinct Texture Fine Medium Medium coarse to coarse Medium Luster Low Dull Lustrous Natural Growth Defects Gum and mineral deposits Natural Durability Perishable Susceptible to insect attack Non-durable Non-resistant to termites Non-resistant to powder post beetles Moderately durable Durable Highly resistant to decay and wood destroying insects Drying Defects Splitting Distortion Checking Slight surface checking Severe surface checking Moderate surface checking Ease of Drying Fairly Easy Rapidly Slowly Variable results. Moderate Kiln Drying Rate Naturally dries slowly Drying rate is fairly rapid to fast Naturally dries quickly Rapid Tree Size Bole length is 20-30 m Trunk diameter is 100-150 cm Sapwood width is 5-10 cm Tree height is 30-40 m Tree height is 10-20 m Sapwood width is 10-15 cm Product Sources Although flat-sawn lumber exhibits an attractive figure, the heartwood is generally too small for furniture work. Comments General finishing qualities are rated as good Blunting Effect Little Blunting effect on machining is severe Cutting Resistance Easy to saw Difficult to saw Cutting Resistance with green wood is difficult The timber is extremely heavy, tough, very strong, and exceptionally hard, and is very difficult to saw.
