453 Carex diandra Schrank

Syn.: C. teretiuscula Good.

This boreal species belongs to the circumpolar plants (Hultén, Circumpol. I, p. 126 and map 120). It also occurs in New Zealand, as a native plant, thus being a bipolar plant (Du Rietz in Acta phyt. Suec. 13/1940, p. 215). The closely related C. prairea Dew. occurs in N. America.
