Wood Identification
Anatomic Description Of Wood
Wood diffuse porous. Occasionally vessels in radial multiples of 4 or more common. Vessels per mm2 5 to 20. Vessels per mm2 less than 6 (rare). Simple perforation plates. Vessel-ray pits similar to intervessel pits in size and shape. Occasionally intervessel pi Axial parenchyma aliform. Axial parenchyma confluent. Occasionally prismatic crystals in non-chambered axial parenchyma cells. Occasionally prismatic crystals in chambered axial parenchyma cells and/or in fibers. 3 to 4 cells per parenchyma strand. 5 to 8 cell 4 to 10 rays per mm (medium). Ray height more than 1 mm. Larger rays more than 4 seriate. Prismatic crystals in radial alignment in procumbent ray cells (chambered cells). Body ray cells procumbent with mostly 2 to 4 rows of upright and/or square marginal cel Fibers very thick walled. Fibers with simple to minutely bordered pits.
