The main range of var. saskatchewanensis is the Cypress Hills; records are known also from the prairie regions of southern Saskatchewan. The differences from the type variety are considerable and constant, and var. saskatchewanensis is perhaps more similar to Crataegus chrysocarpa var. chrysocarpa although where sympatric its fruit is larger.
