Description Of The Tree
Botanical Description
It is an evergreen, medium-sized tree up to 32 m tall. The bole is straight, cylindrical, branchless for up to 22 m, up to 80 cm in diameter, sometimes with short buttresses.

Non Timber Uses
The axial canals are readily noticeable because of the gum patches in wood.
Wood Identification
Anatomic Description Of Wood
Wood diffuse porous. Vessels per mm2 5 to 20. Vessels per mm2 less than 6 (rare). Vessel-ray pits reticulate and/or foraminate. Multiple perforation plates. Axial parenchyma in marginal or in seemingly marginal bands. Paratracheal axial parenchyma scanty and/or vasicentric. 3 to 4 cells per parenchyma strand. 5 to 8 cells per parenchyma strand. Axial parenchyma in narrow bands on lines up to 3 cells wide. Occasion 4 to 10 rays per mm (medium). Occasionally body ray cells procumbent with over 4 rows of upright and/or square marginal cells (Kribs-I). Body ray cells procumbent with mostly 2 to 4 rows of upright and/or square marginal cells (Kribs-II). Body ray cells proc Fibers very thin walled. Fibers with simple to minutely bordered pits.
