Leucaena diversifolia, the wild tamarind or red leucaena, is a species of flowering plant in the family Fabaceae, native to Mexico and Central America. It has been introduced as a cattle fodder in many tropical and subtropical locales around the world. It and its hybrid with Leucaena leucocephala are as aggressively invasive as L. leucocephala itself.
