I place under this name a plant I received from Louisville, Georgia, 

 which agrees with the preceding in size, habit, and conformation of tne 

 leaves and panicle; it differs in having its flower larger, its chaff more con- 

 spicuously three-cleft, the leaves more strongly serrate, all with the under 

 surface ferruginous, almost tomentose, and covered with glandular dots.
