|discussion=<p><i>Crataegus lassa</i> is particularly abundant around its type locality of Selma, Alabama. The species normally has big, floppy leaves. The type material has rather shorter leaves than most specimens seen commonly near Selma today and is notable for having a few small terminal lobes. <i>Crataegus</i> illudens is barely different but has somewhat longer leaves and leaf tips more often entire. <i>Crataegus</i> panda is a form with a slightly shorter and relatively wider leaf, minutely crenate on the margins; also see the discussion under 144. <i>C. lanata</i>.</p>
