The species is apparently naturalized but may be the result of former habitation. Flowers mainly in the dry season (rarely November to as late as May). Fruit maturity time has not been determined. Native to the East Indies; cultivated and escaped throughout tropical America. In Panama, reported from low and middle elevations in moist and wet areas, often in pastures (Holdridge, 1970); known from tropical moist forest in the Canal Zone, Bocas del Toro, Colón and Panama.
