Wood Identification
Anatomic Description Of Wood
Wood diffuse porous. Occasionally vessels of two distinct diameter classes, wood not ring-porous. Tangential diameter of vessel lumina 100 micras or less (very small). Occasionally vessels per mm2 less than 6. Occasionally vascular/vasicentric tracheides pres Axial parenchyma in marginal or in seemingly marginal bands. Paratracheal axial parenchyma scanty and/or vasicentric. Axial parenchyma aliform. Axial parenchyma confluent. Two cells per parenchyma strand. 3 to 4 cells per parenchyma strand. 5 to 8 cells per par 4 to 10 rays per mm (medium). Occasionally larger rays more than 4 seriate. Occasionally rays exclusively uniseriate. Occasionally body ray cells procumbent with one row of upright and/or square marginal cells (Kribs-III). Fibers with simple to minutely bordered pits.
