Wood Identification
Anatomic Description Of Wood
Wood diffuse porous. Occasionally tangential diameter of vessel lumina 200 micras or more. Occasionally tyloses common. Vessels per mm2 5 to 20. Vessels per mm2 less than 6 (rare). Simple perforation plates. Vessel-ray pits coarse in marginal rows. Intervessel p Paratracheal axial parenchyma scanty and/or vasicentric. Two cells per parenchyma strand. 3 to 4 cells per parenchyma strand. 5 to 8 cells per parenchyma strand. 4 to 10 rays per mm (medium). Occasionally larger rays more than 4 seriate. Occasionally silica bodies in the ray cells. Prismatic crystals in radial alignment in procumbent ray cells (chambered cells). Occasionally body ray cells procumbent with over 4 rows Septate fibers present. Fibers very thin walled. Fibers with simple to minutely bordered pits.
