Varieties 3 (3 in the flora). Crataegus coccinea is found from extreme southeastern Minnesota, Wisconsin, and Illinois through the southern Great Lakes area to coastal Maine, and in the Appalachians at higher altitudes to North Carolina; it is common in the north of its range. Crataegus coccinea varies in leaf shape and planeness and in fruit shape. In some areas, more or less pure populations of the different variants occur. It is easiest to group the variation around two relatively strongly marked varieties with ten or fewer stamens, vars. coccinea and pringlei, between which intermediates are common, and the 20-stamen var. fulleriana.

Varieties 4 (4 in the flora). Crataegus schuettei ranges from Wisconsin through the southern Great Lakes to southern New England, to North Carolina. Recent discoveries add the Ozarks and may add Minnesota (see discussion under C. fluviatilis) to the documented range. Variety schuettei closely resembles C. macrosperma, differing principally in its often larger flowers, 20 stamens, usually glandular-serrate sepal margins, and larger fruit but is not nearly so variable as C. macrosperma; the other varieties are very rare. Still, the four varieties are fairly distinct. Crataegus basilica appears to be the southern form of the type variety and is very like sympatric C. macrosperma except for stamen number.
