Wood Identification
Anatomic Description Of Wood
Wood diffuse porous. Vessels exclusively solitary (over 90%). Tangential diameter of vessel lumina 100 micras or less (very small). Occasionally vessels with colored deposits. Vessels per mm2 more than 20 (very abundant). Occasionally helical thickenings in ve Apotracheal axial parenchyma diffuse and/or diffuse in aggregates. Paratracheal axial parenchyma scanty and/or vasicentric. Occasionally prismatic crystals in non-chambered axial parenchyma cells. 5 to 8 cells per parenchyma strand. 4 to 10 rays per mm (medium). Occasionally body ray cells procumbent with mostly 2 to 4 rows of upright and/or square marginal cells (Kribs-II). Body ray cells procumbent with one row of upright and/or square marginal cells (Kribs-III). Fibers very thick walled. Fibers with distinctly bordered pits.
