The leaves of this grass are narrow, smooth, and hairless, with ligules that measure 2 to 7 millimeters long. Its reproductive flowering panicles range from 3.5 to 15 centimeters long, have an open, sparse structure, and carry between 10 and 40 spikelets. The spikelets themselves are 4.5 to 8 millimeters long, compressed along their sides, and hold 2 to 6 florets each.
