Densely cespitose, the culms 2.5-5 dm. high, very slender, 
1.5 mm. thick at base, weak, aphyllopodic, roughened above, 
equalling leaves, light brownish tinged and fibrillose at base. 
Leaves with well-developed blades four to six to a fertile culm 
on lower fourth, but not bunched, the sheaths tight, not septate- 
nodulose, the blades flat, 1-1 75 mm. wide, light green. Spikes 
mostly four, androgynous, the two upper closely contiguous, the 
lower strongly separate, with two to six perigynia, the staminate 
flowers few and inconspicuous; lowest bract setaceous, erect, 
prolonged and often overtopping the culm; the others less de- 
veloped. Scales ovate, obtuse, thin, white-hyaline with green 
midvein, about width of but shorter than body of perigynium. 
Perigynia at first erect, at maturity more or less strongly spreading, 
plano-convex with slightly raised margins ventrally, deep green, 
nerveless or obscurely nerved, roughened on margins above,
