Common names: Chickenfoot grass
Treatment appears in FNA Volume 25. Treatment on page 222.

Culms 20-70 cm, erect. Blades 2-22 cm long, 4-10 mm wide, flat or folded, apices obtuse or mucronate. Panicles with 3-10 branches; branches 3-9 cm. Spikelets 2-2.5 mm; florets 2. Lower glumes 0.9-1.3 mm, acute; upper glumes 1.6-1.8 mm, obovate, apices bilobed, lobes obtuse, awned, awns 0.4-0.7 mm; calluses sparsely hairy; lowest lemmas 2.1-2.5 mm, ovate, tawny to reddish-brown at maturity, lateral-veins and keels with spreading, white, 0.5-1 mm hairs, apices mucronate; second lemmas 1.2-1.5 mm, obconic, truncate. Caryopses 1.1-1.2 mm. 2n = unknown.

Discussion
