Wood Identification
Anatomic Description Of Wood
Wood diffuse porous. Occasionally tangential diameter of vessel lumina 100 micras or less. Occasionally vessels with colored deposits. Vessels per mm2 5 to 20. Occasionally vessels per mm2 less than 6. Simple perforation plates. Vessel-ray pits similar to inter Apotracheal axial parenchyma diffuse and/or diffuse in aggregates. Paratracheal axial parenchyma scanty and/or vasicentric. Prismatic crystals in chambered axial parenchyma cells and/or in fibers. Occasionally two cells per parenchyma strand. Occasionally axi 4 to 10 rays per mm (medium). Occasionally larger rays more than 4 seriate. Prismatic crystals in radial alignment in procumbent ray cells (chambered cells). Homogeneous rays and/or sub-homogeneous rays (all ray cells procumbent). Fibers very thin walled. Fibers with simple to minutely bordered pits.

Drying Defects
Ease of Drying: Seasoning is rather difficult. Drying Defects: It is prone to collapse, internal checking and warp. Kiln Schedules: Schedule suggested for Australian species. For New Zealand material USFD schedule T6-D2 and UK schedule E are recommended. Air seasoning is advisable before careful kiln drying, including reconditioning.
