Wood Identification
Anatomic Description Of Wood
Wood diffuse porous. Tangential diameter of vessel lumina 100 micras or less (very small). Vessels per mm2 5 to 20. Vessels per mm2 less than 6 (rare). Simple perforation plates. Vessel-ray pits similar to intervessel pits in size and shape. Intervessel pits sm Paratracheal axial parenchyma scanty and/or vasicentric. Axial parenchyma aliform. Axial parenchyma confluent. Occasionally 5 to 8 cells per parenchyma strand. Occasionally axial parenchyma in narrow bands on lines up to 3 cells wide. Occasionally axial parenc 4 to 10 rays per mm (medium). Occasionally larger rays more than 4 seriate. Occasionally silica bodies in the ray 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: Air seasoning is quite rapid. Boards 25 mm thick can be air dried in 2 to 2.5 months. Drying Defects: Slight bowing, twisting and some end checking are reported. Staining may also occur. In Myanmar, the wood of this species reportedly does not split during seasoning, but it is very liable to staining. Kiln Schedules: The wood can be kiln dried rapidly, but a mild kiln schedule is recommended.
