Wood Identification
Anatomic Description Of Wood
Wood diffuse porous. Occasionally vessel clusters common. Tyloses common. Vessels per mm2 5 to 20. Vessel-ray pits reticulate and/or foraminate. Simple perforation plates. Intervessel pits medium, 7 to 10 micras. Axial parenchyma absent or extremely rare, non visible with magnifying glass (8x). Paratracheal axial parenchyma scanty and/or vasicentric. 3 to 4 cells per parenchyma strand. 5 to 8 cells per parenchyma strand. 4 to 10 rays per mm (medium). Occasionally rays exclusively uniseriate. Silica bodies in the ray cells. Prismatic crystals in radial alignment in procumbent ray cells (chambered cells). Body ray cells procumbent with one row of upright and/or square marginal Septate fibers present. Fibers very thin walled. Fibers with simple to minutely bordered pits.
