Natural Distribution
It is widely distributed all over the Amazon basin. In Peru it is found in the departments of Loreto, Ucayali and Madre de Dios.
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. I Axial parenchyma apparent with the naked eye. Axial parenchyma lozenge-aliform. Axial parenchyma thick lozenge-aliform. Axial parenchyma confluent. Prismatic crystals in chambered axial parenchyma cells and/or in fibers. 3 to 4 cells per parenchyma strand. 4 to 10 rays per mm (medium). Rays 1 to 4 seriate. Homogeneous rays and/or sub-homogeneous rays (all ray cells procumbent). Fibers with simple to minutely bordered pits.
