About

Senna uniflora, the oneleaf senna, is a species of flowering plant in the family Fabaceae. It is native to Mexico, Central America, the Caribbean, Colombia, Venezuela, and most of Brazil, and has been introduced to India, Mauritius, and Réunion. Although it is somewhat weedy and invasive, it is used to out-compete the pernicious weed Parthenium hysterophorus.
