Plants perennial; cespitose, with innovations, without rhizomes, not glandular. Culms (60)75-130 cm, erect. Sheaths glabrous, apices hairy, hairs to 4 mm; ligules 0.1-0.3 mm; blades (5)8-20 cm long, (1)2-3(4) mm wide, flat to involute, abaxial surfaces glabrous, adaxial surfaces mostly scabridulous, long ciliate basally. Panicles (7)10-20(28) cm long, (2.5)4-15 cm wide, ovate, open; primary branches (3)5-10(13) cm, diverging 20-60° from the rachises, wiry, somewhat capillary, naked basally; pulvini glabrous or sparingly hairy, hairs shorter than 2 mm; pedicels 1-10 mm, appressed, scabridulous.
