Stems usually clustered, l°-2 high, slender, erect, smooth; 

 leaves shorter or longer than the culm, ^"-1" wide, smooth, rough-

 2 or 3 upper contiguous, the others 2"-0" apart, 5-12 flowered; 

 bracts bristle-shaped or filiform^ extending from an ovoid or

 tapering to a flat rough edged bidentate beak, twice longer than

 exceeding the culm ; perigynia oval-lanceolate, erect or spreading ; 

 6cale broadly ovate, obtuse or acutish, sometimes mucronate. 



Var. minor Boott. This differs from the last in its larger and
