Perennial. May. 



Root fibrous, tufted, not creeping. Stems straight and firm, 2 feet 

 high, leafy in the lower part only, very sharply triangular, with 

 compressed, rough, cutting angles ; the interstices concave 3 the 

 summit about twice as thick as the main stalk of the spike, into 

 which it is suddenly contracted. Leaves deep green, taller than 

 the stem, rather broad, with a rough keel and edges, to be 

 handled cautiously. Spike twice or thrice compounded, oblong, 

 obtuse, erect, 2 or 3 inches long, usually dense, or slightly in- 

 terrupted, with several long, taper, rough, spreading bracteas, 

 ovate at their base, from the lower part of the sj)ike -, but these 

 are not constantly protruded. Ultimate spikekts ovate, dense, 

 with numerous barren Jlorets above the fertile ones. Scales 

 ovate, acute ; the lower ones especially rather abrupt, with long 

 points. Fruit widely spreading, brown, ovate, ribbed, tapering 

 into a flat, serrated beak, notched at the point, but less rigid, or 

 prickly, than in C. muricata.

 derstood its limits or synonyms.
