Plants rhizomatous; rhizomes with scales not inflated, not imbricate. Culms to 80 cm, relatively soft, solitary or in small clumps. Sheaths mostly glabrous, throat sometimes sparingly pilose, lower sheaths often wrinkled; ligules 0.2-0.6 mm; blades 6-12 cm long, 5-8 mm wide, loosely involute, disarticulating from the sheaths, abaxial surfaces glabrous, adaxial surfaces glabrous or sparsely pilose, margins smooth. Panicles 4-14 cm, with (1)2-3(7) branches; branches 2-11 cm, alternate, loosely appressed, not twisted, lower and upper branches more or less equally imbricate, with 5-30 spikelets. Spikelets 10-15 mm. Glumes straight, mostly appressed pubescent, only the margins glabrous; lower glumes 7-10 mm, narrow, acuminate, obtuse, or rounded; upper glumes 10-15 mm, acuminate (rarely obtuse); lemmas mostly appressed pubescent, margins and basal portion of the keels glabrous, apices acuminate; anthers 3-6.5 mm, well-filled, dehiscent at maturity. 2n = 60.
