Origin/Endemic status: Endemic

Taxonomy Comments: Gaddy (1986) named Hexastylis rhombiformis; the correct name for the species is Hexastylis memmingeri, however, which has priority and unquestionably represents the same taxon, with a type locality at Memminger's estate "Tranquillity" in Flat Rock, Henderson County, NC. Barringer (1993) considered the species merely a form of Asarum contractum, but electrophoretic and morphologic studies have indicated that it is distinct from H. contracta, and more closely related to H. virginica (Murrell et al. 1998; R. Wyatt, pers. comm.).
