Originating in Mexico, it is now widespread or invasive on tropical islands around the world, including the West Indies, as a consequence of active human dispersal and disturbance. Using mixed methods research, we assessed the species’ (1) historical geographic spread throughout the Americas, (2) local ethnobotanical importance in Jamaica, and (3) biomedical potential as an herbal medicine. Methods included georeferencing of time-stamped herbarium collections from pre-1900 to 2016, literature review, and ethnobotanical research in rural and urban Jamaica (n = 58 participants). Results demonstrated that A. leptopus has spread aggressively in the West Indies since the 1950s. It has become a problematic invasive species in urban Jamaica, which has likely facilitated its local popularity as an herbal medicine. In urban Jamaica, ethnobotanical interviews ranked the species as the fourth most frequently reported medicinal plant. In contrast, A. leptopus was present but did not dominate the vegetation in rural Jamaica, and was never mentioned during interviews. The biomedical literature offers limited support for its biological activity, while showing no acute toxic effects. The ethnobotany of A. leptopus showcases the dynamic interplay between people, plants, and the environment.
