Anatomic Description Of Wood
Wood diffuse porous. Tangential diameter of vessel lumina 200 micras or more (large). Vestured pits. 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 10 m Axial parenchyma in marginal or in seemingly marginal bands. Paratracheal axial parenchyma scanty and/or vasicentric. Axial parenchyma aliform. Axial parenchyma confluent. Prismatic crystals in non-chambered axial parenchyma cells. Occasionally prismatic cryst 4 to 10 rays per mm (medium). Larger rays more than 4 seriate. Prismatic crystals in radial alignment in procumbent ray cells (chambered cells). Prismatic crystals in the ray cells. Body ray cells procumbent with one row of upright and/or square marginal cell Septate fibers present. Fibers very thin walled. Fibers with simple to minutely bordered pits.
