|discussion=<p>The range of <i></i>var.<i> ovata</i> is not precisely documented and may be wider than noted. The variety appears to be well represented in Arkansas and Louisiana. The type specimen is of a rare form with particularly large leaves, some distinctively lobed, that is restricted to Missouri. A form with smaller and almost always unlobed leaves, also included here, is the most abundant of this variety. Intermediates with <i></i>var.<i> lanceolata</i> and <i></i>var.<i> viridis</i> are common. Forms with black scaly bark, relatively large flowers (said to be 20 mm diam.), thornless, and upland habitat were referred to <i>Crataegus</i> blanda, though specimens from the type tree have smaller (14–15 mm diam.) flowers. As the bark of <i>C. viridis</i> characteristically exfoliates in large flakes and is usually whitish or pale gray, the topland habitat of <i>C. blanda</i>, as well as the original collector’s comments on its bark, and its type, which cannot be differentiated from <i></i>var.<i> ovata</i> in the herbarium, suggest that the nature of the mature bark may need to be taken into account more seriously in the taxonomy of this species. Rare ovata-like forms with pink anthers and growing in atypically dry habitats in northeastern Missouri, perhaps hybrid, may be referred to <i>C. davisii</i> Sargent and C. pechiana Sargent and perhaps no longer exist.</p>
