General: Perennial, strongly tufted grass from rhizomes, not bulbous-based; stems erect, wiry, sometimes solid, 40-100 (120) cm tall.
Leaves: Sheaths usually closed to the tops, minutely rough to long stiff-hairy; blades rough (and often slightly soft-hairy) on the upper surfaces, usually smooth on the lower surfaces, finely-veined, 1-4 mm wide, flat to in-rolled, the base often short-hairy or somewhat stiff-hairy; ligules usually open in front, more or less fringed with fine hairs to sparsely hairy-fringed (the hairs sometimes as long as the membrane), finely rough-hairy, usually closed and projecting upward in front in broad, rounded to sharp-pointed, triangular teeth, 1-3 mm long.
Flowers: Inflorescence a narrow panicle 10-20 cm long, the branches short, appressed; spikelets closely (2-) 3- to 6-flowered, 10-17 mm long; lower glumes 6-8 mm long, 5-nerved, the upper ones 8-10 mm long, 7-nerved; lemmas strongly fringed with fine hairs on the lower halves, especially along the margins, obscurely 9- to 11-nerved, rounded or with shallow notches at the tips, about 10 mm long, inconspicuously awned, usually with fragile awn tips 0.5-3 mm long; anthers (3) 4 mm long.
