Not before reported from Iowa, and probably rather rare 

 within our limits. It much resembles the preceding species, 

 from which it is distinguished by its wider leaves and pubes- 

 cent sheaths.

Common on prairies, well distributed throughout the state. 

 This sedge is of considerable value for pasturage, being 

 greedily eaten by cattle. An attenuate form of this collected 

 by the author in Emmet county in 1882, and by F. W. John- 

 son in Poweshiek county, is the Carex meadii var. bebbii 

 (Olney) Arthur, Cont. Fl. Iowa, V, 67 (1884). It seems to 

 be only an occasional state caused by the plants growing 

 among tall grasses in lower ground. The typical C. tetanica 

 Schk., though reported from Iowa, has probably not yet been 

 collected within our limits. Specimens so labelled in the I. A. 

 C. herbarium are referred to C. meadii Dew. by Prof. Bailey.
