Wood Identification

Anatomic Description Of Wood

Wood diffuse porous. Vessels solitary and in short radial multiples. Tangential diameter of vessel lumina 150 to 200 micras (medium). Vessels per mm2 10 to 20 (abundant). Occasionally vessels per mm2 less than 6. Simple perforation plates. Vessel-ray pits simil Axial parenchyma confluent. Axial parenchyma oblique and/or sinuous. Prismatic crystals in chambered axial parenchyma cells and/or in fibers. 5 to 8 cells per parenchyma strand. Rays exclusively uniseriate. Silica bodies in the ray cells. Homogeneous rays and/or sub-homogeneous rays (all ray cells procumbent). Septate fibers present. Fibers with simple to minutely bordered pits.
