Wood Identification
Anatomic Description Of Wood
Wood diffuse porous. Occasionally vessels exclusively solitary (over 90%). Tangential diameter of vessel lumina 150 to 200 micras (medium). Vestured pits. Vessels per mm2 less than 6 (rare). Simple perforation plates. Vessel-ray pits similar to intervessel pits Axial parenchyma in marginal or in seemingly marginal bands. Paratracheal axial parenchyma scanty and/or vasicentric. Axial parenchyma lozenge-aliform. Prismatic crystals in chambered axial parenchyma cells and/or in fibers. 5 to 8 cells per parenchyma strand 4 to 10 rays per mm (medium). Rays non-storied. Rays 1 to 4 seriate. Homogeneous rays and/or sub-homogeneous rays (all ray cells procumbent). Body ray cells procumbent with one row of upright and/or square marginal cells (Kribs-III). Non-septate fibers. Fibers with simple to minutely bordered pits.
