Discussion
Variety rugosa is fairly common from Missouri to the mountains of North Carolina, then northward through the range of the species. The variety often has the most proportionately wide and most deeply incised leaves of the Crataegus pruinosa group. The leaves also characteristically have sharper and longer marginal teeth than other varieties. Extremes are C. mackenziei with acute lobes and C. seducta with rather obtuse lobes.
Unnamed plants of the southern Appalachian piedmont, very likely worthy of at least varietal rank, will key here and are differentiated from var. rugosa as follows: leaf blade 4–6 cm (3–7 cm in var. rugosa), laminas thin (finally chartaceous to somewhat coriaceous in var. rugosa), basal corners of leaf rounded, bases often subcordate (not conspicuously rounded, bases rarely subcordate in var. rugosa).
