FLORA OF VERMONT 15 



Panicum dichotomum of Gray's Manual, etc., is at present conceived to 

 include a number of closely related forms. The specific distinctions are not 

 well established, however, and the nomenclature is in a confused state. All 

 available Vermont specimens have been submitted to Professor Scribner and 

 he recognizes among them the following species. There are numerous 

 other forms, especially in the pubescent group which it is not possible as 

 yet to name satisfactorily.
