Discussion

When M. C. Provance and A. C. Sanders named Calystegia felix, they noted that Brummitt had long included specimens of C. felix within his circumscription of C. sepium subsp. binghamiae and that the names C. sepium subsp. binghamiae Brummitt and C. sepium subsp. limnophylla (Greene) Brummitt belong to a single subspecies circumscription. They chose to call that subspecies C. sepium subsp. binghamiae (Greene) Brummitt.
