IDENTIFICATION DU BOIS
Description anatomique du bois
Wood diffuse porous. Occasionally tangential diameter of vessel lumina 200 micras or more. Vessels per mm2 5 to 20. Simple perforation plates. Vessel-ray pits similar to intervessel pits in size and shape. Intervessel pits small, 7 micras or less. Occasionally paratracheal axial parenchyma scanty and/or vasicentric. Axial parenchyma aliform. Occasionally axial parenchyma confluent. Occasionally prismatic crystals in non-chambered axial parenchyma cells. 5 to 8 cells per parenchyma strand. Occasionally a Occasionally rays of two distinct sizes. Larger rays more than 4 seriate. Prismatic crystals in the ray cells. Occasionally body ray cells procumbent with over 4 rows of upright and/or square marginal cells (Kribs-I). Body ray cells procumbent with mostly 2 t Fibers with simple to minutely bordered pits.

OUVRABILITÉ
Effet d'émoussement
It is considered to have a moderate blunting effect on the cutting elements.
Usinage
It is moderately easy to work if it is free of tension wood. Sometimes difficult due to crystalline deposits, which blunt tools readily.
Rabotage
It usually gives a rough surface due to interlocked grain.
Tournage
30
Cintrage à la vapeur
The wood is suitable for bent work.
