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 less than 6 (rare). Simple perforation plates. Vessel-ray pits similar to intervessel pits in size and shape. In Axial parenchyma absent or extremely rare, non visible with magnifying glass (8x). Occasionally paratracheal axial parenchyma scanty and/or vasicentric. Prismatic crystals in chambered axial parenchyma cells and/or in fibers. 4 to 10 rays per mm (medium). Rays commonly 2 seriate.
