IDENTIFICATION DU BOIS
Description anatomique du bois
Wood diffuse porous. Occasionally vessels exclusively solitary (over 90%). Tangential diameter of vessel lumina 200 micras or more (large). Vestured pits. Vessels per mm2 less than 6 (rare). Simple perforation plates. Vessel-ray pits similar to intervessel pits Axial parenchyma in marginal or in seemingly marginal bands. Paratracheal axial parenchyma scanty and/or vasicentric. Axial parenchyma lozenge-aliform. Axial parenchyma storied. Prismatic crystals in chambered axial parenchyma cells and/or in fibers. 3 to 4 ce 4 to 10 rays per mm (medium). Rays storied. Rays 1 to 4 seriate. Occasionally prismatic crystals in the ray cells. Body ray cells procumbent with one row of upright and/or square marginal cells (Kribs-III). Non-septate fibers. Fibers with simple to minutely bordered pits.

Grain
Straight or slightly interlocked, sometimes with an influence on further processing operations.
Texture
The texture is mostly medium to coarse.
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. Sensible to termites attack. Heartwood is sensible to Lyctus attacks.
