Clumps small to medium-sized, not stoloniferous, the culms 5- 

 9 dm. high, exceeding the leaves, strongly roughened on the angles 

 beneath the head. Leaves with well-developed blades usually four 

 to six to a fertile culm, on the lower half but not clustered, the 

 sheaths long and loose, the ligule not prolonged, the blades flat, 

 3-7 mm. wide, usually 2-4 dm. long, roughened especially on the 

 margins and towards the apex ; sterile culms very leafy ; spikes 

 eight to fifteen, alternately and usually loosely arranged in a flex- 

 uous moniliform head 3-5 cm. long, less than 1 cm. broad, the? 

 spikes orbicular or suborbicular, 5-8 mm. long, 4-7 mm. wide, 

 straw-colored or greenish or even brownish, blunt at the apex, sub- 

 clayate-tapenng at base, the staminate flowers basal, few, but their 

 scales rather conspicuous, the perigynia 1 5-30, ascending-spread- 

 ing with conspicuous often widely divergent beaks ; lower bract 

 (when developed) setaceous and much shorter than the head; 

 upper bracts scale-like ; scales lanceolate or ovate-lanceolate, ob- 

 tuse to acutish, straw-colored with hyaline margins, often brownish- 

 tinged, narrower and much shorter than the perigynia ; perigynia 

 straw-colored or brownish, lanceolate, flat, more or less strongly 

 distended over the achene, noticeably but narrowly wing-margined 

 to the base, 3.25-5 mm. long, about 1.5 mm. wide, nerved on both 

 surfaces round-tapering at base, tapering into the serrulate biden- 

 tate beak, which is one third to one half the whole length ; achenes 

 lenticular, short-stipitate, 1.5 mm. long, 0.5 mm. wide, oblong 

 stigmas two.
