1918] The Grasses of Illinois 357 



The earlier botanists of the state assert that this species is native 

 here, and that it is found in moist situations in prairies, fields, road- 

 sides, ditch banks, etc. It is one of the common pasture grasses and is 

 also cultivated for hay. A low variety is cultivated as a lawn grass 

 under the name of creeping bent.

 '91, 142; Huett '97, 130; Cowles '00, 106. 



This varietj^ on account of the many intergrading forms, is not 



easily distinguished from the species. It is usually found in dryer 



situations and is not so tall, from 9 to 18 inches being the average 



height. The panicle is smaller and usually more open and spreading. 



The leaves are smaller and the ligule is generally much shorter.
