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 lindheimeri is relatively widespread in south-central Texas. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
