Plants perennial ; culms in dense tufts, slender, erect or spreading, 10 to 30 cm. tall ; 

 sheaths glabrous, pilose at the throat ; blades mostl_v clustered at the base of the plants, 5 to 

 15 cm. long, I to 2 mm. wide but mostly narrowly involute, tapering to a slender point, glabrous 

 beneath, scabrous on the upper surface; panicle erect, narrow and more or less spikelike, often 

 somewhat interrupted, 5 to 15 cm. long, mostly less than i cm. wide, the branches short and 

 appressed, the lower i to 2 cm. long; spikelets mostly 6 to 8-flowered, about 5 mm. long, the 

 florets scarcely disclosing the glabrous rachilla ; glumes acuminate, 2 to 3 mm. long, the first 

 often longer than the first lemma; lemmas about 2 mm. long, rather obtuse, glabrous; palea 

 nearly as long as the glume, scabrous on the keels (fig. 20).
