Anatomic Description Of Wood
Wood diffuse porous. Vessels solitary and in short radial multiples. Tangential diameter of vessel lumina 100 micras or less (very small). White deposits in heartwood vessels. Occasionally tyloses common. Vessels per mm2 more than 20 (very abundant). Simple per Paratracheal axial parenchyma scanty and/or vasicentric. Occasionally axial parenchyma storied. 3 to 4 cells per parenchyma strand. 4 to 10 rays per mm (medium). Rays non-storied. Rays 1 to 4 seriate. Homogeneous rays and/or sub-homogeneous rays (all ray cells procumbent). Fibers with simple to minutely bordered pits.
