Wild Oat. Avena fatua L. This annual plant has much the 

 appearance of the oats in cultivation, of which some consider 

 this the parent form. The species has attached to the back of 

 the floret a conspicuous awn, twisted and bent when dry, besides 

 the firm floral glume is thinly clothed with stiff slender hairs, 

 and these aid it much in distribution by adhering to the fleeces 

 of animals and to the inside of grain sacks. Troublesome in 

 Oregon, California, Canada and neighboring regions where eereals 

 are extensively grown, but as yet seldom seen in Michigan. In- 

 troduced from Europe.
