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 Paratracheal axial parenchyma scanty and/or vasicentric. Axial parenchyma lozenge-aliform. Prismatic crystals in chambered axial parenchyma cells and/or in fibers. 3 to 4 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). Septate fibers present. Fibers with simple to minutely bordered pits.
