Lantana is a genus of about 150 species of perennial flowering plants in the verbena family, Verbenaceae.
Lantana species, especially L. camara contain pentacyclic triterpenoids that cause hepatotoxicity and photosensitivity when ingested by grazing animals such as sheep, goats, bovines and horses. This has led to widespread livestock loss in the United States, South Africa, India, Mexico, and Australia.
