Wood Identification
Anatomic Description Of Wood
Vessels per mm2 10 to 20 (abundant). Wood diffuse porous. Occasionally vessels exclusively solitary (over 90%). Tyloses common. Tangential diameter of vessel lumina 100 to 150 micras (small). Vessel-ray pits larger than the intervessel pits. Intervessel pits sc Axial parenchyma in marginal or in seemingly marginal bands. Axial parenchyma in discontinuous tangential lines. Heterogeneous rays and/or multiseriate heterogeneous rays. Fibers with distinctly bordered pits.
