P. amarum Ell. Sea-beach Panicum. 



I have not seen this species. It is admitted to the flora of the 

 State upon the authority of Professor W. S. Blatchley, who reports 

 it as occurring in Vigo County. The form is a sea beach form, and 

 its occurrence in our bounds must be regarded as very exceptional.

Found in marshy places, especially in wet sandy or gravelly soils, 

 in the southern counties. Usually abundant.
