40 ROCHESTER ACADEMY OF SCIENCE. [Oct. 8, 



as given in "Z/i/ of Pteridophyta and Spermatophyta growing without 

 cultivation in Northeaster?! North America'", wherever the names of 

 our plants as given in that publication are different from the names 

 used in Gray's Manual the new nomenclature names are also given, 

 in brackets. When only the author's name is changed, that also is 

 given in brackets. In other words, all bracketed matter is upon the 

 authority of the new nomenclature. 



In all cases where the catalogue name is different from the name 

 of the same plant in the fifth edition of the Manual, the latter name 

 is inserted, immediately following, in parenthesis. All special refer- 

 ences to the Manual are to the fifth edition. 



All ordinal and generic names and synonyms will appear in the 

 index. 



In the list of plants the names are included of a few which are 

 not regarded as fully established, but such plants are not given a 

 number. (See page 12.) 



In the cases of "rare" or "scarce" plants the localities are given 

 and the names of the collectors. In a few instances no locality is 

 given, on account of the absence of such record in the list of the 

 collector, who is deceased or inaccessible. The other descriptive 

 lerms and comments are self-explanatory. 



Typography and reference marks. — Each species, variety, or marked 

 form regarded as an established member of our flora is given a cata- 

 logue number. Those without numbers are not fully established. 



Heavy-faced type indicates species believed to be indigenous. 

 Names of introduced species are printed in small capitals, as are also 

 the popular names. 



Parentheses following catalogue names enclose the names used 

 in Gray's fifth edition, as stated above. 



Brackets indicate that the enclosed matter is the designation 

 given in the "new nomenclature", as explained above. 



Parentheses, within the brackets, are used in the "new nomen- 

 clature" to cite the original authority for a species which has been 

 transferred from one genus to another. The name following is that 

 of the author of the new binomial. 



The name of the discoverer of a plant new to our district, or a 

 new station of a rare or scarce plant, is given in italics. An exclama- 

 tion point after a name indicates that the compilers have verified the 

 discovery.
