Picramnia pentandra is the most common species in the West Indies and is found sporadically along the South American coast. To date, it has not been found in Central America or Mexico. It is quite likely, however, that further collecting will prove that it is a native Mesoamerican species. It is characterized by its pentamerous flowers, glabrous leaves with prominent reticulate venation, and smooth, shiny, obovoid fruits.
