Wood Identification
Anatomic Description Of Wood
Wood diffuse porous. Vessels solitary and in short radial multiples. Occasionally tangential diameter of vessel lumina 200 micras or more. Occasionally white deposits in heartwood vessels. Vessels per mm2 less than 6 (rare). Simple perforation plates. Vessel-ra Paratracheal axial parenchyma scanty and/or vasicentric. Axial parenchyma lozenge-aliform. Occasionally axial parenchyma confluent. Occasionally prismatic crystals in chambered axial parenchyma cells and/or in fibers. 3 to 4 cells per parenchyma strand. 4 to 10 rays per mm (medium). Rays exclusively uniseriate. Homogeneous rays and/or sub-homogeneous rays (all ray cells procumbent). Septate fibers present. Fibers with simple to minutely bordered pits.
