Discussion

Carex concinna is common in northern Canada and Alaska, particularly in the western mountains in the montane zone. It is often abundant, along with C. richardsonii, on open gravelly or sandy banks of spring flood channels. Superficially, C. concinna looks quite similar to C. deflexa Hornemann and C. rossii Boott of sect. Acrocystis. It differs from them in its strongly sheathing, short-bladed bracts, perigynium indument of coarse, wrinkled hairs, and minutely ciliate pistillate scale apices.
