Andropogon crinitus Thunb., Fl. Jap, 40. pl. 7. 1784.
Perennials; culms tufted, erect, 3-6-noded, nodes bearded. Ligule short, ciliated. Inflorescence a single raceme, 1.5-3 cm long; rachis-joints ciliated, about 3/5 as long as the spikelet. Spikelets paired, dimorphic, the pedicellate spikelet smaller than the sessile one, both with 2 long awns of about 1.5-2.5 mm long. Sessile spikelets oblong, about 1.8-2 mm long; glumes papery; lower glume truncate, fringed, about 1.8 mm long, 2-nerved, awnless; upper glume with a longer awn, 1-nerved, as long as the lower, or slightly longer; lemma membranous; lower lemma oblong-lanceolate, nerves obscure, about 1.2 mm long, 2-cleft, awnless, palea wanting; upper lemma as long as the lower, with a long awn; upper palea membranous, filiform, about 1-1.8 mm long; stamen 1.
