Wood Identification

Anatomic Description Of Wood

Wood diffuse porous. Vessels solitary and in short radial multiples. Tangential diameter of vessel lumina 100 to 150 micras (small). Vessels per mm2 10 to 20 (abundant). Simple perforation plates. Vessel-ray pits similar to intervessel pits in size and shape. I Axial parenchyma in marginal or in seemingly marginal bands. Paratracheal axial parenchyma scanty and/or vasicentric. Occasionally axial parenchyma aliform. Axial parenchyma storied. Prismatic crystals in chambered axial parenchyma cells and/or in fibers. Two 4 to 10 rays per mm (medium). Rays storied. Rays exclusively uniseriate. Homogeneous rays and/or sub-homogeneous rays (all ray cells procumbent). Fibers with simple to minutely bordered pits.
