Wood Identification
Anatomic Description Of Wood
Wood diffuse porous. Occasionally vessels exclusively solitary (over 90%). Tangential diameter of vessel lumina 100 to 150 micras (small). Tyloses common. Vessels per mm2 10 to 20 (abundant). Simple perforation plates. Vessel-ray pits coarse throughout the ray Paratracheal axial parenchyma scanty and/or vasicentric. Paratracheal axial parenchyma thin vasicentric. 5 to 8 cells per parenchyma strand. 4 to 10 rays per mm (medium). Rays 1 to 4 seriate. Prismatic crystals in the ray cells. Homogeneous rays and/or sub-homogeneous rays (all ray cells procumbent). Oil and/or mucilage cells at marginal cells of ray parenchyma. Oil and/or mucilage cells associated Septate fibers present. Fibers with simple to minutely bordered pits.
