Lindernia saxicola M.A. Curtis has been known only from Tallulah Gorge, Rabun Co., Georgia, and Hiwassee Gorge, Cherokee Co., North Carolina (Curtis 1843), and was last collected by the late Dr. E.T. Wherry in 1932. Damming the rivers totally destroyed populations at both sites, with the species being considered extinct. This species is under review (category 1, as possibly extinct) for inclusion on the Federal list of endangered or threatened species (Lamberton 1980).
