fhe following discussion will consider name, dis- 

 tribution (especially local occurrence and tsrpical habita't), 

 notes on diagnosis (with relation to quick recognition by 

 striking characters, as well as with relation to doubtful 

 points and difficult determinations), and notes on vari- 

 ation of species* In general, and except as otherwise 

 specified, the"Tariation" of species will be considered 

 for the Cayuga flora, and on the basis of the writer's 

 specimens. It is important, of course, in considering 

 such "Tariations", to remember the immense influence of 

 the enrironment on plant characters; the writer has tried, 

 for the most part, to call attention to positive or more 

 or less probable Indivations of hereditary or "genetic" 

 variation. 



"6ray*s New Manual of Botany" (7th Bd. ) has been 

 taken as the standard of nomenclature. Britton and 

 Brown's Illustrated Flora of the Northern States and 

 Canada", which has often been consulted in cases of dif- 

 ficult diagnosis, has been the main source for the history
