Crataegus Edsoni appears to be most closely related to C. Forbesae, 
Sarg., of central Massachusetts and Connecticut, differing from that 
species in its thinner and more deeply lobed leaves, pink, not dark 
red, anthers, and larger fruit. It is named for its discoverer, the late 
Arthur Woodbury Edson, a student at the University of Vermont and 
at the time of his death in June 1905 assistant physiologist in the 
Bureau of Plant Industry of the Department of Agriculture of the 
United States, in charge of experiments in Texas in breeding cotton.
