Description Aerial rhizome simple, 2-4 mm. in diam., to at least 10 cm. tall, surrounded by blackish, ragged-fibrous leaf-sheaths. Leaves 1-1.4 dm. long, 5-8 mm. wide at the base, tapering gradually to the apex, glabrous on the under surface, granular-roughened above, flat for most of their length, slightly bicarinate at apex, margins sharp-scabrous, almost saw-edged. Flowering culms laxly ascending, flattened, densely appressed-pubescent, about 0.5 mm. wide, including inflorescence about 1.5 dm. high; basal sheath 1.5-2 cm. long. Inflorescence of 5-6 tufts of spikelets; slieaths of the inflorescence dark-brown, minutely hoaiT-X)ubeseent, 4-10 mii?. long, the leaf -like points as long as the sheaths. Staminate spikelets about 4 mm. long, 1-1.5 mm. in diam. ; sterile glumes 4-6, from ovate to broadly lanceolate, mucronate, minutely pubescent above the middle ; stamiiiiferoiis glumes 5-8, lanceolate, acute, glabrous; stamens under eacli glume 4-8. Pistillate spikelets 3 mm. long, 1-1.5 mm. in diam., the glumes 5-6, ovate to lanceolate, mucronate, minutely pubescent to glabrate. Achene 1.2-1. 7 mm. long,
0. 5. mm. in diam., glabrous, dark brown, tapering into a blunt-truiicated beak about as long as the body of the achene; beak glabrous, or sometimes minutely puberulent at the apex. Tricarpellary markings faint. Perianth scales minute, orbicular ; marginal hairs few, about one-half as long as the body of the achene, straight or somewhat twisted. Stigmas linear, dark browM.
