Distribution

Amaprá present, C America present, Caribbean Islands present, Guianas present, Northern America, Southern America: Bolivia (Bolivia present), northern S America present
About 160 species from Mexico through C America, to the Caribbean islands and into northern S America as far south as Bolivia and east to Amaprá in Brazil; 4 species are so far known from the Guianas, a 5th, C. scandens, included here because it might be expected in our area.
