Taxonomic Comments
Murray in FNA (2002, vol. 23) recognizes Carex chalciolepis, C. epapillosa, and C. heteroneura as distinct species. Kartesz (1994, 1999) recognized C. chalciolepis and C. epapillosa as varieties of C. heteroneura. Welsh et al. (2015) also recognize C. chalciolepis and C. epapillosa as varieties of C. heteroneura, saying plants in Utah show a continuum of characters but that trends in morphology, as well as geography, seem sufficient to maintain a distinction at the varietal level.
