The species is reported to occur widely in Brazil, and extends into northeastern Perú, the Serrania de San Lucas region of Colombia, and the Guyana.
IDENTIFICACIÓN DE LA MADERA
Descripción anatómica de la madera
Wood diffuse porous. Vessels solitary and in short radial multiples. Occasionally tangential diameter of vessel lumina 200 micras or more. White deposits in heartwood vessels. Tyloses common. Vessels per mm2 less than 6 (rare). Simple perforation plates. Vessel- Axial parenchyma apparent with the naked eye. Axial parenchyma in marginal or in seemingly marginal bands. Axial parenchyma in discontinuous tangential lines. Axial parenchyma in thick bands. 3 to 4 cells per parenchyma strand. Axial parenchyma bands more than 4 to 10 rays per mm (medium). Occasionally larger rays more than 4 seriate. Heterogeneous rays and/or multiseriate heterogeneous rays. Body ray cells procumbent with mostly 2 to 4 rows of upright and/or square marginal cells (Kribs-II). Fibers with simple to minutely bordered pits.
