Tephrosia florida
Tephrosia mohrii
Tephrosia florida is recognized by its relatively small, elongate, bicolored leaves with abaxial surfaces strigulose and with reddish venation (including secondary and tertiary veins).
Tephrosia × intermedia (Small) G. L. Nesom & Zarucchi is a putative hybrid between T. chrysophylla and T. florida (C. E. Wood Jr. 1949; D. Isely 1998; G. L. Nesom and J. L. Zarucchi 2009). Synonyms are Cracca intermedia Small, C. floridana Vail, C. smallii Vail, and T. × floridana (Vail) Isely. The hybrid is said to occur in association with the two putative parents, sporadically from Alabama, Florida, Georgia, and Mississippi, and its origin as a recurrent hybrid seems a reasonable hypothesis. According to Isely, it most closely resembles T. florida, differing in its shorter petioles and broader, fewer leaflets; both parents are variable in these features, and it is difficult to confirm that the putative hybrids are consistently intermediate in morphology. Perhaps the only sure way to identify the hybrid is to see it in the field, in company with the parents and in contrast to them.

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.
