General: Perennial tufted grass from fibrous roots; stems disarticulating at the nodes, (7) 10-70 (100) cm tall.
Leaves: Sheaths soft-hairy to smooth; blades 0.8-3 (4) mm wide, 6-15 (20) cm long, smooth to soft- hairy, curled with age; ligules less than 1 mm long, fringed with short hairs.
Flowers: Inflorescence a narrow panicle with 5 to 10 (18) spikelets, the lower branches with 2 or 3 spikelets, these with stalks shorter than the spikelets; spikelets 7-15 mm long; lemmas (2.5) 3-4 (5) mm long, soft-hairy, or sometimes smooth over the back, the apical teeth pointed to stiff-awned, 0.5-2 mm long, also awned from the back, the awns abruptly bent, 5-8 mm long, the calluses about as long as wide, with stiff hairs laterally; anthers to 2.5 mm long.
Mesic to dry shorelines, open forests and meadows in the lowland and montane zones; frequent throughout BC; N to AK, YT and NT, E to NF and S to ME, MA, PA, SC, FL, MS, LA, TX, NM, ID and OR; Greenland.
A shadeintolerant, submontane to montane, transcontinental North American grass. Species occurs on very dry to moderately dry, nitrogen-poor soils (Mar humus forms) within boreal, temperate, and cool mesothermal climates; their occurrence decreases with increasing elevation and precipitation. Sporadic in open-canopy, young-seral forests on strongly drained and shallow soils on watershedding sites; often present in non-forested communities on rock outcrops. Characteristic of moisture-deficient sites.
