Not ca^spitose. Rootstock extensively creeping, producing stems 

 and tufts of radical leaves at distant intervals. Radical leaves nume- 

 rous, channelled, keeled, with a long tritjuetrous point, recurved. 

 Stems rather slender, subcylindrical, solid, with 1 to 3 sheathing 

 leaves, with the lamina resembling that of the radical leaves, or short 

 and subulate-triquetrous. Spikes solitary, several (rarely solitary), 

 more or less stalked and sessile, in a simple umbellate corymb, obco- 

 nical-obovate and subtruncate at the apex in fruit. Peduncles glabrous, 

 drooping. Bracts unequal, resembling the leaves ; one or two of the 

 lowest usually considerably longer than the largest peduncle. Glumes 

 lanceolate-triangular, fuscous with broad white scarious margins and 

 apex. Hypog}-nous bristles very numerous, in fruit straight and four or 

 five times as long as the glumes. Nut narrowly elliptical, acuminated,
