Wood Identification
Anatomic Description Of Wood
Wood diffuse porous. Occasionally tangential diameter of vessel lumina 100 micras or less. Vessels per mm2 5 to 20. Occasionally vessels per mm2 more than 20. Intervessel pits scalariform. Vessel-ray pits reticulate and/or foraminate. Multiple perforation plate Axial parenchyma in marginal or in seemingly marginal bands. 5 to 8 cells per parenchyma strand. Axial parenchyma in narrow bands on lines up to 3 cells wide. Axial parenchyma bands more than 3 cells wide. 4 to 10 rays per mm (medium). Oil and/or mucilage cells associated with the axial and/or ray parenchyma (idioblasts). Body ray cells procumbent with one row of upright and/or square marginal cells (Kribs-III). Fibers very thin walled. Fibers with distinctly bordered pits.
