Compactly tufted annuals. Culms 29–40 cm high, branched, compressed; internodes smooth, glabrous. Leaves: ligule to 0.5 mm long; blade involute or conduplicate, setaceous, not coiled or flexuose at maturity, to 11 cm long, to 1.8 mm wide. Inflorescences 7–19 cm long, to 8 cm wide, loosely contracted; branches loosely appressed, to 3.5 cm long, naked at base. Glumes inverse, notched or entire, awned, 1-nerved, glabrous or pubescent; lower glume 17–30 mm long, acute; upper glume 13–20 mm long. Lemma 7–8 mm long, shorter than both glumes, convolute, tuberculate apically or punctate, with a distinct articulation; column distinct, 15–35 mm long, scaberulous; awns slightly but visibly unequal, straight; median awn 32–76 mm long; lateral awns 26–70 mm long, terete. Caryopsis terete, 3.7–5.6 mm long, more than twice embryo length.
