Natural Distribution
In Brazil it is reported in Amazonas, Para, Amapa and Roraima.
Non Timber Uses
Fairly often oily or waxen patches can be observed.
Wood Identification
Anatomic Description Of Wood
Wood diffuse porous. Vessels solitary and in short radial multiples. Tangential diameter of vessel lumina 200 micras or more (large). Vessels per mm2 less than 6 (rare). Simple perforation plates. Vessel-ray pits similar to intervessel pits in size and shape. O Axial parenchyma apparent with the naked eye. Occasionally axial parenchyma in marginal or in seemingly marginal bands. Axial parenchyma confluent. Axial parenchyma in discontinuous tangential lines. Axial parenchyma in thick bands. Axial parenchyma storied. Pr 4 to 10 rays per mm (medium). Occasionally rays and/or axial elements irregularly storied. Rays storied. Rays 1 to 4 seriate. Body ray cells procumbent with one row of upright and/or square marginal cells (Kribs-III). Fibers with simple to minutely bordered pits.
