This species is separated from other members of the section 
Crus-galli by its broad, lobed leaves. 
It ranges farther east than any of the other Crus-galli do 
naturally. It ranks with Crataegus Jonesae Sarg., of the Maine 
coast, Crataegus Bicknellii Eggl., from Nantucket, and Crataegus 
Wilhamsti Eggl., from the Flathead basin, Montana, etc., as a 
good example of an isolated geographical species.
