Sheaths at first close around the culms, smooth or minutely scabrid; ligule very short, densely short ciliate; blade narrowly linear, long-tapering, acuminate, 8–15 cm long, 2–4(–5) mm wide, mostly glabrous, smooth or scabrous.
Inflorescence much exserted, spike-like, cylindrical, 2–5 cm long, bristles fine, erectly spreading. Spikelets obovate-elliptical, 2.5–3 mm long, each subtended by 4–8 bristles 8–15 mm long. Lower glume 50–75% spikelet length, 3–5-nerved, acute or apiculate; upper 75–100% spikelet length, 5–7-nerved, broadly ovate to elliptical.
