Discussion
Variety dissona, found from Missouri to Wisconsin and through the Great Lakes to New England, then south to Georgia, is widely scattered throughout the range of var. pruinosa and an unnamed southern form (see var. rugosa). Its detailed distribution is not well known but it is almost certainly more widespread than recorded. The variation in leaf shape of var. dissona closely parallels that of var. pruinosa. Crataegus disjuncta is a similar form with particularly large leaves; C. brachypoda has cream anthers.
