IDENTIFICATION DU BOIS
Description anatomique du bois
Wood diffuse porous. Vessels exclusively solitary (over 90%). Tangential diameter of vessel lumina 200 micras or more (large). Vessels per mm2 less than 6 (rare). Simple perforation plates. Occasionally multiple perforation plates. Scalariform perforation plate Paratracheal axial parenchyma scanty and/or vasicentric. Prismatic crystals in short chains in chambered axial parenchyma cells. 4 to 10 rays per mm (medium). Rays non-storied. Larger rays more than 4 seriate. Occasionally prismatic crystals in the ray cells. Body ray cells procumbent with over 4 rows of upright and/or square marginal cells (Kribs-I). Non-septate fibers. Fibers with distinctly bordered pits.

DESCRIPTION GÉNÉRALE DU BOIS
Teinte
The sapwood is paler than heartwood. The heartwood is reddish brown or yellow-brown , it is clearly demarcated.
Index de Teinte (1 = Noir, 7 = Jaune clair)
5
Grain
Straight; grain has no particular influence on drying, machining and finishing qualities.
Texture
This species is reported to have a medium to coarse texture.
Luster
This wood is frequently low in luster.
Durabilité naturelle
Not durable; important risks of decay attacks at any processing step, from logs up to final products. It must receive preservative treatment. Resistant to termites attack. Heartwood is sensible to Lyctus attacks.
Index de durabilité naturelle (1 = Très élevée, 7 = Très faible)
5
Tensions internes de croissance
No residual growth stresses are found.
Teneur en silice
Silica Content: It is reported to have a negligible amount of silica. Contents over 0.05% may affect wood processing. Silica Value: 0.02
Résistance à l'imprégnation
Easy to treat with a full penetration of the preservative products using vacuum-pressure method.

Défauts dus au séchage
Ease of Drying: Boards 25 mm thick take about 3 months to air dry. Drying Defects: When seasoned with care, end-splitting and surface checking are not significant during drying. Kiln Schedules: The timber kiln dries rapidly but marked collapse may occur in early stages of seasoning. This can be remedied by reconditioning.
