Carex bicolor

Carex bicolor is a tufted perennial sedge growing to a height of about . The grass-like leaves are mostly basal, greyish-green with blades up to long and wide, linear, strongly keeled, with parallel veins and long pointed tips. The inflorescence has a triangular stem about the same length as the leaves. It bears two or three spikes of small flowers, the terminal spike having staminate flowers for the lowest third and pistillate flowers above. The floral scale is shorter than the perigynium that surrounds the achene and has brown or reddish-black edges with a green midvein. ==Distribution and habitat==

Carex bicolor has a pan-boreal distribution. In North America it is present in most of Canada, Greenland, in Alaska and the Aleutian Islands. In Northern Europe and Asia, it is present at both low and high altitudes, but further south it is limited to higher altitudes. Its southerly limit is the mountains of Spain, France, Italy, Switzerland and Austria. It often grows in lime-rich habitats such as moist tundra, at the upper edge of beaches, near pools in wet sand, in poorly vegetated marshes and patches of moist bare mud. ==References==
