Microstegium fauriei Honda subsp. geniculatum (Hay.) Koyama, Grass. Jap. Neighb. Reg.429. 1987
Culm geniculate, about 1 mm in diameter. Blade 6-8 cm long by 5 mm wide; ligule tongue-shaped, pubescent on the back. Racemes 4, subdigitately arranged, 5-8 cm long. Spikelets paired, monomorphic, the upper pedicellate, the lower sessile, about 3.5 mm long; rachis-joint longer than the spikelet. Lower glume linear, as long as the spikelet, subcoriaceous, 2-keeled, short ciliate along keels, furrowed and siliceous on the back, 2-toothed at the apex; upper glume deltoidlanceolate, 1-keeled, margins inrolled, fimbriate, about 3 mm long, with a slender awn of about 3.5 mm long. Lower floret reduced. Upper floret minute, chartaceous, lemma about 0.3 mm long, with an awn 14-20 mm long.
