SORGHUM Pers. 



S. Halapense (L.) Pers. Johnson Grass. 



"This was introduced, and is occasionally found escaped from 

 cultivation; it is considered valuable farther south and on the dry 

 lands farther west, but its good qualities have not yet been deter- 

 mined here. It is very late in starting in the spring, but holds on 

 well into the autumn, and for that reason might be valuable as fur- 

 nishing fall feed." (J. Troop, Grasses of Indiana, p. 42.) 

 Flowers September and October.

(P. fluitans Kunth. )

P. setaceum Michx. Slender Paspalum. 



Common in dry, sandy soil in open places throughout the State. 

 Stem mostly decumbent.
