General:
Perennial, tufted grass from fibrous roots; stems 10-40 (50) cm tall.
Leaves:
Sheaths open; blades flat to somewhat in-rolled, 1.5-3.5 mm wide; ligules entire, rounded, about 1 mm long.
Flowers:
Inflorescence an ultimately open panicle, 5-15 cm long, the branches rough, spreading to reflexed, the lower branches of fruiting inflorescences usually descending, occasionally spreading; spikelets (3-) 5- to 6-flowered, the spikelet stalks usually uniformly rough; glumes egg-shaped, usually minutely more or less fringed with fine hairs, the lower ones barely 1 mm long, the upper ones (1.5) 2 mm long; lemmas broadly egg-shaped, the margins entire below, roughly sharp-toothed near the tips, often more or less fringed with fine hairs, sparsely hairy near the base, (1.4) 1.6-1.8 (2) mm long, broadly rounded to blunt and jagged at the tips; paleas usually equalling or slightly exceeding the lemmas; lodicules barely 0.5 mm long; anthers 0.5-0.8 mm long.
Notes:
Generally recognized as introduced but some populations with branches of the fruiting inflorescence nondescending, including some in BC, are possibly intergradational with P. nuttalliana, and may be native.
