Wood Identification

Anatomic Description Of Wood

Wood diffuse porous. Vessels exclusively solitary (over 90%). Tangential diameter of vessel lumina 200 micras or more (large). Occasionally tyloses common. Vessels per mm2 less than 6 (rare). Vessel-ray pits reticulate and/or foraminate. Simple perforation plat Apotracheal axial parenchyma diffuse and/or diffuse in aggregates. Paratracheal axial parenchyma scanty and/or vasicentric. 5 to 8 cells per parenchyma strand. Over 9 cells per parenchyma strand. Axial parenchyma in narrow bands on lines up to 3 cells wide. Rays more than 10 per mm (abundant). Silica bodies in the ray cells. Occasionally body ray cells procumbent with mostly 2 to 4 rows of upright and/or square marginal cells (Kribs-II). Occasionally body ray cells procumbent with one row of upright and/or squa Fibers with distinctly bordered pits.
