IDENTIFICATION DU BOIS
Description anatomique du bois
Vessels per mm2 less than 6 (rare). Wood diffuse porous. Occasionally vessels exclusively solitary (over 90%). Tangential diameter of vessel lumina 200 micras or more (large). Vestured pits. Vessel-ray pits similar to intervessel pits in size and shape. Simple Axial parenchyma lozenge-aliform. Occasionally axial parenchyma in marginal or in seemingly marginal bands. 3 to 4 cells per parenchyma strand. Rays exclusively uniseriate. Non-crystals in ray cells. Non-septate fibers. Fibers with simple to minutely bordered pits.

DESCRIPTION GÉNÉRALE DU BOIS
Teinte
The sapwood is pale yellow to grey. The heartwood is red-brown, it is clearly demarcated.
Index de Teinte (1 = Noir, 7 = Jaune clair)
4
Grain
Straight or slightly interlocked, sometimes with an influence on further processing operations.
Texture
This species is usually reported to have a coarse texture.
Luster
The wood luster is reported to be rather low.
Durabilité naturelle
Moderately durable to decay. Without preservative treatment, this species can be used only under risk of occasional re-humidification. It is not suited for uses with risks of permanent or long-lasting humidification. Moderately resistant to termites attack
Index de durabilité naturelle (1 = Très élevée, 7 = Très faible)
3
Tensions internes de croissance
No growth stresses are reported in this species.
Teneur en silice
Silica Content: Negligible contents of silica are found in timber of this species. Amounts over 0.05% may affect the wood processing. Silica Value: 0.02
Résistance à l'imprégnation
Difficult to treat with only a low penetration of the preservative products.
