IDENTIFICATION DU BOIS

Description anatomique du bois

Wood diffuse porous. Occasionally vessels exclusively solitary (over 90%). Tangential diameter of vessel lumina 100 to 150 micras (small). Non-vestured pits. Vessels per mm2 6 to 10 (medium). Simple perforation plates. Vessel-ray pits similar to intervessel pit Apotracheal axial parenchyma diffuse and/or diffuse in aggregates. Occasionally axial parenchyma in discontinuous tangential lines. 3 to 4 cells per parenchyma strand. Rays more than 10 per mm (abundant). Rays non-storied. Rays exclusively uniseriate. Prismatic crystals in the ray cells. Heterogeneous rays and/or multiseriate heterogeneous rays. Non-septate fibers. Fibers with simple to minutely bordered pits.

DESCRIPTION GÉNÉRALE DU BOIS

Teinte

The sapwood is white, pink or grey darkening to dark brown but never black. The heartwood is the heartwood core attains 15 to 22.5 cm, it is clearly demarcated.

Index de Teinte (1 = Noir, 7 = Jaune clair)

1

Grain

Straight; grain has no particular influence on drying, machining and finishing qualities.

Texture

This wood has a somewhat fine texture.

Durabilité naturelle

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.

Index de durabilité naturelle (1 = Très élevée, 7 = Très faible)

1

Tensions internes de croissance

For this species no growth stresses are reported.

Résistance à l'imprégnation

Nearly impossible to treat with a too much low penetration of the preservative substances.
