Discussion | Tephrosia spicata is recognized by its numerous leaflets with raised adaxial venation and long, ebracteate peduncles with long racemes. Cracca flexuosa (Vail) A. Heller is a later homonym that pertains here. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Tephrosia mohrii is known from Covington and Houston counties in Alabama; Okaloosa, Santa Rosa, and Walton counties in Florida; and Ben Hill and Grady counties in Georgia. The species appears to intergrade with T. virginiana. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
