Astragalus tennesseensis Gray ex Chapman (Fabaceae) is a cedar glade endemic that was first collected in Alabama by Professor Thomas P. Hatch in the 1850s. Evidence is presented that suggests his specimen was collected in Colbert County rather than in Lauderdale County, Alabama. The historic distribution of A. tennesseensis in Alabama was confined primarily to the Moulton Valley of the Interior Low Plateau. Recent field surveys have documented seven extant populations of this species in Alabama. Without protection, these populations likely will decline, and the species possibly could be extirpated from the southern portion of its historic range.
