Wood Identification

Anatomic Description Of Wood

Wood diffuse porous. Vessels exclusively solitary (over 90%). Tangential diameter of vessel lumina 100 micras or less (very small). Vessels per mm2 10 to 20 (abundant). Simple perforation plates. Vessel-ray pits similar to intervessel pits in size and shape. In Apotracheal axial parenchyma diffuse and/or diffuse in aggregates. Prismatic crystals in non-chambered axial parenchyma cells. Prismatic crystals in chambered axial parenchyma cells and/or in fibers. 5 to 8 cells per parenchyma strand. Rays more than 10 per mm (abundant). Rays 1 to 4 seriate. Prismatic crystals in the ray cells. Homogeneous rays and/or sub-homogeneous rays (all ray cells procumbent). Fibers with distinctly bordered pits.

Drying Defects

Ease of Drying: It is moderately difficult to air season, it dries at a moderate rate. Drying Defects: Slight checking and moderate warping are reported. Casehardening may occur in thick stock. Kiln Schedules: Drying of pieces over 40 mm is reported to be very difficult, slow drying is recommended.
