Wood Identification
Anatomic Description Of Wood
Wood diffuse porous. Occasionally vessels exclusively solitary (over 90%). 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 Axial parenchyma in marginal or in seemingly marginal bands. Axial parenchyma lozenge-aliform. Axial parenchyma aliform. Occasionally axial parenchyma confluent. Prismatic crystals in chambered axial parenchyma cells and/or in fibers. 3 to 4 cells per parenchy 4 to 10 rays per mm (medium). Rays non-storied. Rays 1 to 4 seriate. 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.
