Wood Identification
Anatomic Description Of Wood
Tyloses common. Vestured pits. Vessels per mm2 5 to 20. Simple perforation plates. Vessel-ray pits coarse throughout the ray cell. Intervessel pits medium, 7 to 10 micras. Apotracheal axial parenchyma diffuse and/or diffuse in aggregates. Axial parenchyma winged aliform (uni or bilateral winged). Axial parenchyma confluent. Prismatic crystals in non-chambered axial parenchyma cells. Occasionally prismatic crystals in chambered 4 to 10 rays per mm (medium). Rays of two distinct sizes. 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). Occasionally septate fibers present. Fibers with simple to minutely bordered pits.
