Discussion
Variety michiganensis resembles var. succulenta but has white anthers. The similar but glabrate Crataegus tanuphylla Sargent was rediscovered in the 1990s in central Pennsylvania. Crataegus laxiflora Sargent [C. succulenta var. laxiflora (Sargent) Kruschke is similar to var. michiganensis] but has unusually lax inflorescences.
