Wood Identification
Anatomic Description Of Wood
Wood diffuse porous. Occasionally vessels with colored deposits. Vestured pits. 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. Intervessel pits medium, 7 to 1 Occasionally axial parenchyma in marginal or in seemingly marginal bands. Paratracheal axial parenchyma scanty and/or vasicentric. Axial parenchyma aliform. Occasionally axial parenchyma confluent. Prismatic crystals in chambered axial parenchyma cells and/or 4 to 10 rays per mm (medium). Occasionally larger rays more than 4 seriate. Prismatic crystals in radial alignment in procumbent ray cells (chambered cells). Occasionally body ray cells procumbent with mostly 2 to 4 rows of upright and/or square marginal cel Fibers with simple to minutely bordered pits.
