General Description

Sapwood is not differentiated from the heartwood, which is cream to light yellow in colour. Grain is straight to shallowly interlocked. Texture is moderately fine to rather coarse and even. Vessels are with simple perforations, medium-sized, few or moderately few in number, mostly in radial multiples of 2 to 9 in a series, the rest are solitary with occasional clusters; arrangement rather radial. Wood parenchyma is apotracheal, as irregularly spaced bands which often may be closely spaced and appear as regularly spaced bands. Rays are moderately fine, just visible to the naked eye on the cross- section. Latex traces, which are large radial passages appearing on tangential faces as lensshaped scars, are common.
