Rootstock creeping, with somewhat chordorrhizal branches and elon- 

 gate stolons. Stem erect, rather slender, wiry, rigid, bluntly trigonous, 

 smooth. Leaves about as long as the stem, very stiff, narrowly-lmear, 

 deeply chamielled, involute not keeled, glabrous, rough on the margins, 

 pale green, slightly glaucous; sheaths on the base of the stem at 

 length split, and with filamentous margins. Male spikes 2, more 

 rarely 1, the upper one stalked, rarely subsessile, the second one 

 sessile, cylindrical, slender, acute, with lanceolate acuminate and 

 acute brown glumes Avith pale midribs. Female sj^ikes 1 to 3, rather 

 remote, the lowest one far above the middle of the stem, on a very 

 short included stalk, the upper ones sessile or subsessile, erect, fusi- 

 form-cylindrical, or the upper ones ovoid, dense, many-flowered.
