Discussion
Oeceoclades maculata was first discovered in the United States in Miami-Dade County, Florida in 1974, and is spreading rapidly in central and southern Florida. It is not known whether it escaped from cultivation or arrived in Florida via windblown seeds from the Greater Antilles or the nearby Bahama Archipelago.
