Discussion
The distribution and ecology of Carex muehlenbergii var. enervis are unclear due to confusion with var. muehlenbergii. Plants of var. muehlenbergii that have a veinless perigynium have often been misidentified as var. enervis, but those plants are otherwise identical to var. muehlenbergii. Carex muehlenbergii var. muehlenbergii usually occurs on basic to slightly acidic soils; var. enervis often occurs on more acidic soils. It is not clear, however, whether that correlation is consistent.
