Plants densely cespitose. Culms 5–35 cm, distally scabrous. Leaves 2–3 mm wide.

Discussion

Carex norvegica is an amphi-Atlantic species. Carex norvegica subsp. inserrulata is synonymous with subsp. norvegica in this treatment; however, as some differences can be seen between subsp. inserrulata in Greenland and subsp. norvegica in northern Europe, further study is warranted.
