Sept.-Oct. Doubtless grows in most of the other counties, 

 but it is not recognizable when not in flower. Widely 

 distributed over South Georgia, from the fall-line sand-hills 

 of Richmond (A. Cuthbert) and Taylor (where Elliott dis- 

 covered it) to the flat pine-barrens. See Bull. Torrey Club 

 28: 463. 1901; 31: 12. 1904. 



Also reported from Florida as far down as Tampa, and doubt- 

 less grows in the coastal plain of South Carolina and Alabama 

 as well. 

 S. nutans (L.) Nash; Small, Fl. 66. 1903. 



Sorghum avenaceum (Mx.) Chapm., Fl. 583. i860. 



Dry pine-barrens, berrien, colquitt (1657). Fl. Sept.-Oct. 



Widely distributed in the Eastern United States, most common 

 northward. 



The three known species of this genus have been much con- 

 fused, and it is difficult to identify them from most descrip- 

 tions, because they all look about alike when pressed. But 

 they are amply distinct in life, and were pretty well described 

 by Dr. Chapman in the first edition of his Flora. The other 

 species (Sorghum nutans Chapm., Sorghastrum Linneanum 

 Nash) grows in many places in the upper third of the coastal 

 plain of Georgia.
