No specimens are known from Connecticut; Carex mitchelliana may be expected to occur there. The species is known from fewer than 100 extinct and extant populations located predominantly along the Atlantic and Gulf coastal plains from Massachusetts to Alabama. Allozyme data demonstrated that the taxon, although not common, is genetically diverse and is closely related to the progenitor of the species complex (L. P. Bruederle et al. 1989).
