Natural Distribution

It can be found in Indo-Malayan region.

Wood Identification

Anatomic Description Of Wood

Wood diffuse porous. Tangential diameter of vessel lumina 200 micras or more (large). Vessels per mm2 5 to 20. Vessels per mm2 less than 6 (rare). Vessel-ray pits reticulate and/or foraminate. Simple perforation plates. Intervessel pits medium, 7 to 10 micras. I Paratracheal axial parenchyma scanty and/or vasicentric. Occasionally axial parenchyma aliform. Occasionally axial parenchyma confluent. Occasionally axial parenchyma storied. Two cells per parenchyma strand. 3 to 4 cells per parenchyma strand. Rays less than 4 per mm (rare). Ray height more than 1 mm. Larger rays more than 4 seriate. Body ray cells procumbent with one row of upright and/or square marginal cells (Kribs-III). Fibers very thin walled. Fibers with simple to minutely bordered pits.
