Variety pruinosa is common through the northern range of the species, mainly north of southern Missouri and the Ohio River; it is found southward at middle and higher elevations in the Appalachians. Crataegus bracteata from Missouri is somewhat atypical; the adaxial leaf surfaces are briefly soft-pubescent, and the abaxial midrib permanently hairy. With its somewhat large leaves (5–6 cm) and slightly glandular sepal margins, as well as its very conspicuous bracteoles, it probably represents introgression with C. coccinioides. A red-anthered variant of var. pruinosa with a more deltate-ovate leaf shape, perhaps matching Crataegus tumida, has been collected from New York.
