Carex rossii

Carex rossii is a species of sedge known by the common name Ross’ sedge. It is native to much of western and central North America, from Alaska and northwestern Canada to the American southwest to the Great Lakes region. It grows in many habitat types, including wet and dry areas in forest, sagebrush, prairie, and alpine meadows. This sedge produces a dense clump or solid mat of slender stems up to about 40 centimeters tall from a shallow network of rhizomes. The pale to dark green leaves are usually longer than the stems. The flower cluster contains one or more staminate flower spikes above more rounded pistillate spikes. The fruit is three-sided and covered in a greenish or brownish perigynium.
