"^ 173. Panicum raveneLLi Scribn. & Merr. 



Panicum scoparium major[us] Vasey, U. S. Dept. Agr. Div. Bot. Bull. 8: 32. 1889 

 The author states, "We have only seen this from South Carolina (Dr. Ravenel)." 

 The type, in the National Herbarium, consists of three immature vernal culms. 



Panicum scoparium genuinum Scribn. Tenn. Agr. Exp. Sta. Bull. 7 : 48. 1894. 

 "P. scoparium, Lam., Ell." is cited, and, as it is evident that Scribner is designating 

 Elliott's as the genuine P. scoparium,, Elliott's specimen is considered the type. 



Panicum ravenelii Scribn. & Merr. U. S. Dept. Agr. Div. Agrost. Bull. 24 : 36. 1901. 

 Published as a new name for "Panicum scoparium of Ell. Sk. Bot. S. C. and Ga. 1 : 

 119. 1817. Not Lam. Encycl. 4: 744. 1797." The type, in the Elliott Herbarium, 

 is a single vernal culm with an immature panicle. No locality is cited by Elliott, 

 and none is given on the label; the specimen is presumably from South Carolina. 



This species was referred to Panicum scoparium by Elliott, as stated above, and also 

 by Chapman. a
