more, even if the plants were correctly identified according to the 

 best existing knowledge, hardly a month passes but some taxo- 

 nomist shows that what we have been regarding as a single 

 species is really two or three, or that one of our plants is different 

 from the southern or western or European species to which it was 

 formerly referred ; and it is hard for one who does not specialize 

 in such matters to keep up with them. Fortunately minor errors 

 of identification within generic limits do not materially affect 

 the statistics. 



As far as nomenclature is concerned Taylor's Flora of the vicin- 

 ity of New York* is followed in the majority of cases. But 

 acceptance of a particular style of nomenclature does not bind 

 one to any particular conception of generic and specific limits, or 

 preclude taking advantage of the latest taxonomic developments 

 that may have come to notice. (For examples of the latter, see 

 the footnotes in the list.

t At present many of the hickories are dead or dying from the ravages of a bark 

 beetle. The chestnut has been dying from canker for about ten years, but the 

 dead trees and stumps are easily identified, and have been counted the same as 

 living trees. As far as these trees are concerned therefore this list represents 

 conditions as they were ten years ago. 



J This has been commonly called Q. Prinus L., but that name belongs to a 

 species of more southerly distribution, according to Sargent (Rhodora 17: 40, 

 Feb. 1915)-
