Low grounds, marshes and margins of streams and ponds.

 species of the genus. Within our limits it is often found asso-

Note. — C. engelmanni Steud., Syn. PI. Cyp. 47 (1S53), has been reported 

 from Iowa, but 1 have been unable to find any specimen of this species in 

 any collection in the state. It is reported by Wheeler in Fl. Milwaukee 

 Co., Wis., 1S6; by Tracy in Fl. Mo , 90; by Brendel in Fl Peoriana. SS, and 

 by Webber in Fl. Neb., 95. It probably occirs in the southern part of the 

 state, and can be distinguished from the above, to which it is closely re- 

 lated, by its more slender spikelets, and the tips of the scales not reaching 

 to the succeeding one on the same side.
