Discussion

Varieties 2 (2 in the flora).

The status of Carex crinita var. porteri (Olney) Fernald [C. porteri Olney], a rare, long-beaked taxon known from two sites in Somerset and Lincoln counties, Maine, is in question and is not treated here. It has not been collected since around the early 1900s.
