Distribution Overview
Various species in the Vochysia genus are widely distributed in tropical America, from southern Mexico to Peru, and are most plentiful in the Guianas and Brazil. They are reported to thrive best on coastal plains and alongside waterways, and are often found in nearly pure stands on abandoned farmlands.

Product Sources
The ITTO reports that the species is an important source of timber for export.
Timber produced by species in the genus are used for the same purposes as Qualea timbers, and the two genera are often referred to by the same vernacular name in some localities.
