Wood Identification

Anatomic Description Of Wood

Wood diffuse porous. Tangential diameter of vessel lumina 200 micras or more (large). Tyloses common. Vessels per mm2 5 to 20. Vessel-ray pits reticulate and/or foraminate. Simple perforation plates. Intervessel pits large, 10 micras or more. Axial parenchyma in marginal or in seemingly marginal bands. Prismatic crystals in non-chambered axial parenchyma cells. Prismatic crystals in chambered axial parenchyma cells and/or in fibers. 3 to 4 cells per parenchyma strand. Axial parenchyma in narrow ba 4 to 10 rays per mm (medium). Silica bodies in the ray cells. Body ray cells procumbent with one row of upright and/or square marginal cells (Kribs-III). Fibers with simple to minutely bordered pits.
