IDENTIFICATION DU BOIS
Description anatomique du bois
Wood diffuse porous. Vessels solitary and in short radial multiples. Tangential diameter of vessel lumina 150 to 200 micras (medium). Occasionally white deposits in heartwood vessels. Occasionally tyloses common. Vessels per mm2 10 to 20 (abundant). Simple perf Occasionally axial parenchyma in marginal or in seemingly marginal bands. Paratracheal axial parenchyma scanty and/or vasicentric. Occasionally axial parenchyma aliform. Occasionally axial parenchyma confluent. Prismatic crystals in non-chambered axial parenc Rays more than 10 per mm (abundant). Rays exclusively uniseriate. Prismatic crystals in the ray cells. Homogeneous rays and/or sub-homogeneous rays (all ray cells procumbent). Fibers with simple to minutely bordered pits.
