Treated as nonnative in Florida by the Atlas of Florida Vascular Plants, but as native to South Florida by Weakley (2022). This was presumably collected in Key West twice between 1836 and 1853 (one specimen states "Key West" and the other "Florida"). It is native to Cuba, and tropical America including the Yucatan; we treat it as native and presumed extirpated in South Florida.
