Endangered status

This plant was discovered in 1990 and described to science as a new species in 1991. In 1993 it was added to the endangered species list because it was known from only two locations and both were slated for development. Much of the land was subsequently purchased by the State of Florida, and when more occurrences of the plant were found, the state purchased many of them as well; these lands are mainly located within Etoniah Creek State Forest
