varieties of Flowering Plants and Ferns yet found growing spontaneously in our 

 County, the species being numbered, and the varieties indicated by the letters 



of the Greek alphabet. When there is a variety a. the terely 



inclusive, or the typical form is not found in our section. 



Only those who have engaged in a similar undertaking can fully appreciate the 

 difficulty of compiling even a mere list like this. Having, however, submitted 

 all doubtful and varying forms to well known botanical authorities for determina- 

 tion we feel confident that errors in naming are comparatively few. The size of 

 our field and the limited explorations thft we have been able to make in two or 

 seasons collecting, most of which was done in one town, must be our excuse 

 for the incompleteness of the list. More than nine-tenths oft)

principally to Mr. O. R Willis of White Plains, who has collected extensively in 

 the county, to the New York Catalogue now publishing and to the State Flora.
