|discussion=<p>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 <i>Crataegus pruinosa</i> group. The leaves also characteristically have sharper and longer marginal teeth than other varieties. Extremes are <i>C. mackenziei</i> with acute lobes and C. seducta with rather obtuse lobes.</p><!--
--><p>Unnamed plants of the southern Appalachian piedmont, very likely worthy of at least varietal rank, will key here and are differentiated from <i></i>var.<i> rugosa</i> as follows: leaf blade 4–6 cm (3–7 cm in <i></i>var.<i> rugosa</i>), laminas thin (finally chartaceous to somewhat coriaceous in <i></i>var.<i> rugosa</i>), basal corners of leaf rounded, bases often subcordate (not conspicuously rounded, bases rarely subcordate in <i></i>var.<i> rugosa</i>).</p>
