Taxonomy Comments: Var. aestuariorum Pennell, of s. NJ south to e. VA, is alleged to differ in being shorter, with more rounded leaves, short pedicels (< 2 mm long), a shorter calyx and corolla, and a smaller capsule; it is likely merely a stunted aquatic form, but needs additional study – see Fernald (1950) and Pennell (1935) for additional details.
