Discussion
Variety praecox is similar to var. chrysocarpa except for its pink anthers and is sparsely scattered through the eastern part of the range of the species. Reports from Quebec and Wisconsin are unconfirmed. Forms attributed to Crataegus lemingtonensis in Vermont are said to be locally common and represent two variants, the more common like C. praecox and a second with a distinctive leaf shape and relatively slender and long petiole characteristic of members of ser. Tenuifoliae. The latter represents typical C. lemingtonensis and is perhaps a hybrid.
