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 Axial parenchyma apparent with the naked eye. Axial parenchyma aliform. Axial parenchyma confluent. 3 to 4 cells per parenchyma strand. 4 to 10 rays per mm (medium). Rays of two distinct sizes. Larger rays more than 4 seriate. Heterogeneous rays and/or multiseriate heterogeneous rays. Occasionally oil and/or mucilage cells associated with the axial and/or ray parenchyma (idioblasts). Body ray Fibers with simple to minutely bordered pits.
