Perigynia 4.5–6 mm, distal margins finely serrulate; beak tip hyaline.

Discussion
W. J. Cody (1996) mapped one locality for Carex circinata in Yukon and also stated that its occurrence is disputed. Carex circinata is unexpectedly absent from the adjacent Russian Far East, where a close relative, C. hakkodensis Franchet, occurs (T. V. Egorova 1999).
Selected References
None.
Lower Taxa
