 animals. (la. Seed Co.) 



hairy glumes 4-6 lines long; awns 6-8 lines long; blooming period from June 

 to August. First introduced into the United States from Europe, it is without 

 forage value, and, while not greatly troublesome in Iowa or eastward, has be- 

 come a serious pest farther west, in Utah and Colorado. 



Poisonous properties. This plant produces injuries similar to those caused 

 by Squirrel-tail grass, the awned glumes working in under the teeth causing 

 inflammation and suppuration. Animals eating this grass may lose their teeth 

 as a consequence.
