Pollinia fauriei Hayata, Icon. Pl. Formos. 7: 73. 1918.

Culm geniculate, about 1.5 mm across. Blade 3-5 cm long by 3.5-4 mm wide, covered with tubercle hairs; sheath pubescent; ligule fimbriate on the upper back, about 0.4 mm long. Racemes 4, subdigitately arranged, about 8 cm long. Spikelets paired, monomorphic; rachis-joint longer than the lower spikelet; the upper pedicellate, the lower sessile, about 4 mm long. Lower glume subcoriaceous as long as the spikelet, 2-keeled, furrowed on back, ciliate on keels, shortly 2-toothed; upper glume lanceolate, 1-keeled, keel ciliate, margins inrolled, fimbriate, apex ending into a short awn; upper lemma 1 mm long, hyaline, 2-cleft, fimbriate along margins, with an awn of about 23 mm long, arising from the sinus; upper palea membranous, about 1.5 mm long, with a sinus of the apex; anther about 1.6 mm long.
