Wood Identification
Anatomic Description Of Wood
Wood diffuse porous. Vessels exclusively solitary (over 90%). Helical thickenings in vessel elements present. Simple perforation plates. Vessel-ray pits similar to intervessel pits in size and shape. Intervessel pits medium, 7 to 10 micras. Paratracheal axial parenchyma scanty and/or vasicentric. Ray height more than 1 mm. Larger rays more than 4 seriate. Body ray cells procumbent with mostly 2 to 4 rows of upright and/or square marginal cells (Kribs-II). Body ray cells procumbent with one row of upright and/or square marginal cells (Kribs-III). Septate fibers present.
