Kobresia sibirica, the Siberian bog sedge, is a plant species known from arctic and alpine tundra in Siberia, the Russian Far East, Alaska, Yukon, the Canadian Northwest Territories, Nunavut, British Columbia, 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 (K. macrocarpa, described from Colorado, [2] and K. hyperborea from the Canadian Arctic), [3] but they are more often tentatively regarded as conspecific with K. siberica, but this is pending further investigation. [4] [5] [6] [7]
Kobresia sibirica 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. [4] [8] [9] [10] [11] [12]
