Plants cespitose, usually sparsely appressed-strigose; with cormoid caudices, new shoots developing near bases of old stems. Stems 1–5 (–10+). Peduncles long, slender, bracts 1–5. Phyllaries subequal (outer longest and foliaceous), apices not strongly squarrose. 2n = 10, 20, 30.


Phenology: Flowering late Jul–Sep.
Habitat: Well-drained soils, stream banks and slopes, edges of alkali lakes and flats, prairies and plains, mesic montane habitats
Elevation: 200–2400 m
