Crataegus L. Hawthorne. This genus has been extensively revised 
by Prof. C.S. Sargent in the last few years, and 
our region has not been thoroughly explored. 
Doubtless many other species exist here. Prof. 
Sargent has already enumerated some 60 species 
found in this state. The specific distinctions are 
so fine that none but a specialist can identify them.
