The study by Whittemore et al. (2018) indicated F. biltmoreana is hexaploid and can be recognized by its semicircular or shield-shaped leaf scar, while F. americana s.str. is diploid with crescentic leaf scars partly surrounding the axillary bud. The taxonomy of tetraploids and pentaploids remained uncertain while F. smallii was included in the concept of F. biltmoreana (Whittemore et al. 2018). Nesom (2010) reported F. smallii for Leon Co. in Florida but excluded F. biltmoreana, while Weakley (2020) also reported F. biltmoreana for north Florida.
