Anatomic Description Of Wood
Wood diffuse porous. Colored deposits in heartwood vessels. Vestured pits. Vessels per mm2 less than 6 (rare). Simple perforation plates. Vessel-ray pits similar to intervessel pits in size and shape. Intervessel pits small, 7 micras or less. Apotracheal axial parenchyma diffuse and/or diffuse in aggregates. Paratracheal axial parenchyma scanty and/or vasicentric. Axial parenchyma aliform. Axial parenchyma confluent. Prismatic crystals in chambered axial parenchyma cells and/or in fibers. Homogeneous rays and/or sub-homogeneous rays (all ray cells procumbent). Fibers with distinctly bordered pits.
