Distributed in: Columbia, Ecuador, Guyana, Nicaragua, Panama, Peru, Suriname, Venezuela (Central America, Latin America)
Distribution overview: The genus Vochysia is composed of several shrubs and trees that are distributed throughout tropical America, from southern Mexico to Peru, but are most plentiful in the Guianas and Brazil. Trees are reported to form nearly pure stands on old farmlands, and attain their best development on coastal plains and along waterways.
Common uses: Balusters, Bedroom suites, Bent Parts, Boxes and crates, Building materials, Cabinetmaking, Casks, Ceiling, Chairs, Chests, Concealed parts (Furniture), Decorative veneer, Desks, Dining-room furniture, Dowell pins, Dowells, Drawer sides, Figured veneer, Fine furniture, Floor lamps, Furniture , Furniture components, Furniture squares or stock, General carpentry, Hatracks, Interior construction, Kitchen cabinets, Living-room suites, Millwork, Office furniture, Packing cases, Paddles, Radio - stereo - TV cabinets, Rustic furniture, Sporting Goods, Stairrails, Stairworks, Stools, Stringers, Tables , Utility furniture, Veneer
Product sources: The ITTO reports that the species is an important source of timber and rates as a fairly important export.Timber produced by species in the genus are used for the same purposes as those by the genus Qualea, and the two genera are often referred to by the same vernacular name in some localities.
