Govenia floridana

Govenia floridana, the Florida govenia, is an extinct species of orchid that was endemic to Everglades National Park in Florida. It was discovered for the first time in 1957, with a total populations of 25 individuals, and the last verified report was from the same site in 1964, where the population had declined to just 10 individuals. It is likely that poaching of plants contributed to its decline and extinction.
