Discussion
Variety blanchardii is usually like var. chrysocarpa, but with 20 pink anthers; it ranges from Minnesota and Quebec to Vermont and New York. Eggleston perhaps combined it under Crataegus irrasa because of its leaves being (in specimens seen by him) more like C. irrasa in shape and size than those of C. chrysocarpa. The type material, however, is like C. chrysocarpa in these features.
