Wood Identification
Anatomic Description Of Wood
Wood diffuse porous. Vessels solitary and in short radial multiples. Tangential diameter of vessel lumina 200 micras or more (large). Vessels per mm2 less than 6 (rare). Simple perforation plates. Vessel-ray pits similar to intervessel pits in size and shape. I Paratracheal axial parenchyma thin vasicentric. Occasionally axial parenchyma lozenge-aliform. Occasionally prismatic crystals in chambered axial parenchyma cells and/or in fibers. 3 to 4 cells per parenchyma strand. Rays more than 10 per mm (abundant). Rays exclusively uniseriate. Occasionally silica bodies in the ray cells. Homogeneous rays and/or sub-homogeneous rays (all ray cells procumbent). Occasionally septate fibers present. Fibers with simple to minutely bordered pits.
