Sapwood
is lighter in shade merging gradually into the heartwood, which is yellow
brown, light buff or light brown. Grain is straight or shallowly interlocked.
Texture is slightly coarse and uneven due to the broad rays and wide layers
of parenchyma. Growth rings are distinct, demarcated by layers of terminal
parenchyma. Vessels are medium-sized to moderately large, few to fairly
few, solitary and in radial groups of 2 to 3, with a tendency to tangential
arrangement. Vessels are open. Wood parenchyma is abundant, visible to the
naked eye, with paratracheal parenchyma appearing as borders around the
vessels, sometimes aliform and locally confluent; apotracheal parenchyma as
fairly broad bands which simulate growth rings. Rays are of two distinct
sizes; the larger rays being very broad and conspicuous, the finer rays are
storeyed. The ray pattern on the tangential longitudinal surface is characteristic
and reminiscent of mosquito-netting. |
