Wood Identification
Anatomic Description Of Wood
Wood diffuse porous. Occasionally vessels exclusively solitary (over 90%). Tangential diameter of vessel lumina 200 micras or more (large). Resinous deposits in heartwood vessels. Vestured pits. Simple perforation plates. Vessel-ray pits similar to intervessel Axial parenchyma in marginal or in seemingly marginal bands. Axial parenchyma lozenge-aliform. Axial parenchyma confluent. Prismatic crystals in chambered axial parenchyma cells and/or in fibers. 3 to 4 cells per parenchyma strand. Rays more than 10 per mm (abundant). Rays non-storied. Rays exclusively uniseriate. Homogeneous rays and/or sub-homogeneous rays (all ray cells procumbent). Non-septate fibers. Fibers with simple to minutely bordered pits.

General Wood Description
Color
The sapwood is beige. The heartwood is pinkish brown with dark brown veins, it is clearly demarcated.
Grain
Slightly interlocked grain and variations of the slope are frequent, and could induce distortion during drying.
Texture
The wood is mostly medium in texture.
Luster
The wood is described as low in luster.
Natural Durability
Very durable to decay; without preservative treatment. This species is especially suited for all the uses with risks of permanent or long-lasting humidification. Resistant to termites attack. Heartwood is resistant to Lyctus attacks.

Internal Growth Stresses
For this species no growth stresses are reported.
Resistance To Impregnation
Nearly impossible to treat with a too much low penetration of the preservative substances.
