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. |
