Dry ground in woods; a very pretty and delicate species, 

 closely resembling C. bromoides Schkuhr, from which it is 

 distinguished by its nerveless perigynia and oblong spikes. 

 Dr. Arthur kindly loaned me his original specimen for exam- 

 ination.

Note. — C. bromoides Schkuhr, has been reported from Iowa, but I have 

 been unable to find a specimen in any of the collections examined. It is 

 reported by Prof. Tracy in his Flora of Missouri, p. 92, and by Bruhin in 

 his Flora of Wisconsin, p. 278.

 with crowded leaves on the sterile shoots, which with the 

 long, narrow, cylindrical spikes give the plant an appearance 

 strikingly distinct from any of our other carices.
