SYNONYMY 



The following names have appeared in American botanical litera- 

 ture as applied to grasses growing in the United States. For grasses 

 introduced into the United States from other countries there are here 

 given only the names appearing in American works. No attempt 

 has been made to present the complex synonymy for these introduced 

 grasses given in foreign works. The synonymy for the generic 

 names will be found in The Genera of Grasses of the United States. 13 



For quick reference the names of genera and valid species are ar- 

 ranged in alphabetic order, the names in blackface type. The syno- 

 nyms, in italics, are arranged chronologically under the names to which 

 they are referred. The numbers in parentheses are the numbers these 

 genera and species bear in the body of this work.
