Wood Identification
Anatomic Description Of Wood
Wood diffuse porous. Occasionally vessels exclusively solitary (over 90%). Tangential diameter of vessel lumina 150 to 200 micras (medium). Vestured pits. Simple perforation plates. Vessel-ray pits similar to intervessel pits in size and shape. Intervessel pits Axial parenchyma in marginal or in seemingly marginal bands. Paratracheal axial parenchyma scanty and/or vasicentric. Prismatic crystals in chambered axial parenchyma cells and/or in fibers. 5 to 8 cells per parenchyma strand. 4 to 10 rays per mm (medium). Rays non-storied. Rays 1 to 4 seriate. Homogeneous rays and/or sub-homogeneous rays (all ray cells procumbent). Occasionally septate fibers present. Fibers with simple to minutely bordered pits.

General Wood Description
Color
The sapwood is paler than the heartwood, it has a thickness of 5 to 7.5 cm. The heartwood is red-brown, it is clearly demarcated.
Grain
Straight or slightly interlocked, sometimes with an influence on further processing operations.
Texture
This species is usually reported to have a fine texture.
Luster
Luster is usually low.
Natural Durability
Not durable; important risks of decay attacks at any processing step, from logs up to final products. It must receive preservative treatment. Sensible to termites attack. The heartwood is sensible to Lyctus attacks.
Natural durability index (1= Very high durability, 7=Vey low durability)

Internal Growth Stresses
Residual stresses present in the wood may cause defects while processing the timber.
Resistance To Impregnation
Nearly impossible to treat with a too much low penetration of the preservative substances.
