Natural Distribution
It occurs in Queensland up to Innisfail in jungle-type coastal forests. It is also found in Papua New Guinea and the Philippines.
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. Simple perforation plates. Vessel-ray pits similar to intervessel pits in size and shape. Intervessel pits medium, 7 to 10 micras. Intervessel pi Paratracheal axial parenchyma scanty and/or vasicentric. Axial parenchyma aliform. Axial parenchyma confluent. Two cells per parenchyma strand. 3 to 4 cells per parenchyma strand. 5 to 8 cells per parenchyma strand. Axial parenchyma bands more than 3 cells wide 4 to 10 rays per mm (medium). Larger rays more than 4 seriate. Prismatic crystals in radial alignment in procumbent ray cells (chambered cells). Occasionally body ray cells procumbent with mostly 2 to 4 rows of upright and/or square marginal cells (Kribs-II) Fibers very thick walled. Fibers with simple to minutely bordered pits.
