It grows in the sub-Himalayan tract from the Indus eastwards to Bengal, in Chota Nagpur, Madhya Pradesh, Assam and Burma at elevations of up to 3000 feet (900 m) above sea level. Heartwood Color Red Brown Pink Black Purple Green/grey Whitish Greenish to greyish The wood is described as grayish-white in color, often with darker streaks Sapwood Color White Yellow Brown Grain Even Straight Generally straight, but not always Texture Medium Medium coarse to coarse Luster Low Somewhat lustrous Natural Durability Durable Resistant to termites Susceptible to insect attack Moderately durable Non-resistant to powder post beetles Resistant to powder post beetles The timber has moderate resistance to decay under cover. Seasoned wood is readily attacked by wood boring insects Odor Has an odor Has a taste Drying Defects Distortion Warping can be expected End splitting Checking Ease of Drying Slowly Reconditioning Treatement Little degrade Requires care Green conversion and open-stacking under cover are recommended for satisfactory results during air-seasoning Kiln Drying Rate Naturally dries slowly Drying rate is slow Slow Tree Size Tree height is 30-40 m Tree height is 20-30 m Tree height is 10-20 m Bole length is 10-20 m Trunk diameter is 100-150 cm Tree height is 0-10 m Comments Other Machining Properties The timber is described as heavy, strong, very tough, and very hard.
