Wood Identification
Anatomic Description Of Wood
Wood diffuse porous. Vessels solitary and in short radial multiples. Tangential diameter of vessel lumina 100 micras or less (very small). Resinous deposits in heartwood vessels. Tyloses common. Vessels per mm2 10 to 20 (abundant). Simple perforation plates. Sca Axial parenchyma absent or extremely rare, non visible with magnifying glass (8x). Paratracheal axial parenchyma thin vasicentric. 5 to 8 cells per parenchyma strand. Rays less than 4 per mm (rare). Rays commonly 2 seriate. Oil and/or mucilage cells associated with the axial and/or ray parenchyma (idioblasts). Body ray cells procumbent with one row of upright and/or square marginal cells (Kribs-III).
