Southern Michigan forms the western extension of what is perhaps the richest Crataegus region in the world; certainly in no other part of the world where the genus has been at all carefully studied are there so many species as in the territory extending from the valley of the Genesee River in New York, up both banks of the Niagara River and through southern Ontario into southern Michigan, and nowhere are there more distinct or beautiful species.

It is now possible, however, to distinguish fifty-five species and of these twenty-five are now first described. Eighteen others, briefly described by Ashe from St. Clair county, are also described in this paper from material and notes furnished me by Mr. Dodge. All the St. Clair county species described by Ashe have now been identified with the exception of C. passens, collected at Port Huron, and probably one of the Flabellatue, C. falkix, from "rocky hills near Port Huron," and C. borcalis without other locality than "Michigan."
