GRASSES OF IOWA. 



Rachilla pubescent; empty glumes unequal, the flowering glumes awn- 

 less, or very short-awned, with a rather broad, scarious margin at the 

 obtuse or emarginate apex. Introduced from Europe. Cultivated in 

 United States for hay. June to July. 



Hungarian brome grass is well established in different sections of 

 the state, and has been widely scattered in recent years. A valuable 

 grass for Iowa.
