species, Alopecurus pratensis. 

 Name from Greek alopex, 

 fox, and oura tail, alluding to 

 the cylindric panicle. 



The species of Alopecurus 

 are all palatable and nutri- 

 tious forage grasses, but us- 

 ually are not found in suffi- 

 cient abundance to be of 

 great importance. A. pra- 

 tensis, meadow foxtail, is 

 sometimes used as a meadow 

 grass in the eastern United 

 States ; A. aequalis is the most 

 common on the western 

 ranges.
