Spicis androgynis distigmaticis ovatis confertis alternis, superi- 

 oribus et inferioribus pistilliferis vel raro superne staminiferis, in- 

 termediis staminiferis perraro dioecis ; bracteis ovato-lanceolatis ; 

 fmctibus ovatis rostratis bidentatis convexo-concavis margine cili- 

 ato-serratis vel serralatis, squama ovata acuta paulo longioribus ; 



culmis erectis inferne foliatis. 



Culm 12-18 inches high, triquetrous, leafy towards the base, 

 rough on edges above ; leaves linear, flat, striate, rarely as long as 

 the culm ; spikelets many, ovate, clustered, alternate, the highest 

 and lowest pistillate with often a few staminate florets at the 

 apex, the intermediate often wholly staminate, and sometimes all 

 the spikelets staminate entirely or the plants dioecious ; stigmas 

 two ; fruit ovate, rostrate, serrulate on the margin, convex on the 

 upper side and concave on the lower ; pistillate scale ovate, acute, 

 a little longer than the fruit. 



Common in the north of Europe, and by some considered a 

 variety of C. armaria ; first recognized in the plants of Arctic 

 America by Dr. Boott ; lately found in Wisconsin by I. A. Lap- 

 ham, Esq. The fruit of C. arenaria, L., is broader, less lanceo- 

 late. Prom C. Sartwellii, Dew., which has also lately been 

 found by Dr. Cooley in Mich., this is clearly different.
