Description
"Coarse perennials from rhizomes or hardened bases. Leaves mostly low cauline; blades usually scaberulous; sheaths usually glabrous, margins scarious; ligules membranous to cartilaginous. Panicle elongate; rachis smooth; branches ascending; peduncles 1-20 mm long. Spikelets in pairs, fertile long-ovoid, 5-8 mm long excluding awns, sessile or subsessile, sterile or absent, with long hirsute pedicel, 3-8 mm long; terminal spikelets in 1-3 jointed racemes subtended by 2 subequal sterile pedicels. Glumes cartilaginous, subequal, 1st usually densely hirsute, 2nd glabrous or ciliate; fertile and sterile lemmas thin, hyaline, subequal, fertile lemma awned; palea absent. Grain reddish, flat, ellipsoid to obovoid, 2.5-3 mm long."[1]
"Tufted perennial; culms 0.4-2 m tall, nodes and internodes glabrous. Blades to 6 dm long and 10 mm wide; ligules truncate, 1-4 mm long. Panicle 0.5-3 dm long, 0.2-1.5 dm broad; rachis purplish, smooth, pedicels hirsute apically.
