Wood Identification

Anatomic Description Of Wood

Vessels per mm2 5 to 20. Wood diffuse porous. Tyloses common. Tangential diameter of vessel lumina 100 to 200 micras. Vessel-ray pits reticulate and/or foraminate. Tangential diameter of vessel lumina 100 micras or less (very small). Simple perforation plates. I Paratracheal axial parenchyma scanty and/or vasicentric. Occasionally prismatic crystals in non-chambered axial parenchyma cells. 3 to 4 cells per parenchyma strand. 4 to 10 rays per mm (medium). Occasionally larger rays more than 4 seriate. Prismatic crystals in radial alignment in procumbent ray cells (chambered cells). Body ray cells procumbent with mostly 2 to 4 rows of upright and/or square marginal cells (Kribs-II) Fibers with simple to minutely bordered pits. Septate fibers present.
