Panicum crusgalli. (Barn-yard grass.) 



This is a coarse Lira.-- that grows in barn yards and wherever 

 there are wet, sour places about the premises. Its leaves are one 

 half insh broad, and. when growing well, one to one and ahalf feet 

 Long. The culm is stout and grows from two to ten feet high. 

 The cul ins are b ranching arid the tpikea ire in one to two' inches 

 long and are crowded together forming a long raceme. The .-pikelets 

 are thickly clustered along the branches. The glumes have stiff 

 awns (sometimes wanting, however,) that render the grass, when 

 matured, very difficult to digest. It' properly cut and cured it 

 makes a good hay, and is much prized by many farmers as a sub- 

 stitute for fodder. In some sections the grass is looked upon a a 

 worthless plant and efforts are made to destroy it. Flowers from 

 August to September.
