African Ground Orchid - Oeceoclades maculata, Windley Key Fossil Reef Geologic State Park, Islamorada, Florida. Although this is native to west Africa, it appears that this orchid made its way to the Americas by natural means (i.e. it was not introduced by humans).  Its flower is small, but very pretty up close.
