Carex borealipolaris, the Siberian bog sedge, is a species of plant known from arctic and alpine tundra habitats in Russia ( Siberia, the Russian Far East), Canada ( Yukon, the Northwest Territories, Nunavut, British Columbia), and the United States ( Alaska, Colorado (several counties in the Rockies), Utah ( Duchesne County), Montana ( Carbon County), and Wyoming ( Park County)). Some authorities have considered the North American collections as distinct species (C. macrocarpa, described from Colorado, [1] and K. hyperborea from the Canadian Arctic), [2] but they are more often tentatively regarded as conspecific with C. borealipolaris, but this is pending further investigation. [3] [4] [5] [6]
Carex borealipolaris is a perennial herb spreading by means of underground rhizomes. Culms are up to 40 cm tall. Leaves are narrow and thread-like, up to 15 cm long. Lower spikelets generally have both pistillate and staminate flowers, while uppermost spikelets are staminate only. [3] [7] [8] [9] [10] [11]
