|discussion=<p><i>Crataegus opima</i> is found from southeastern Texas to Georgia.</p><!--
--><p><i>Crataegus opima</i> comprises the smaller leaved members of the series with proportionately broad leaves and more or less obtuse lobes that are few and shallow. Both red- and yellow-fruited forms are known, as are forms with cream or purple anthers. It is possible that, as elsewhere in the series, these forms should be recognized as distinct taxa, but more information would be required to decide this.</p><!--
--><p>A distinctive local form of <i>Crataegus</i> opina is known with ovate to ovate-trullate leaves 5–8 cm, having 5–7(or 8) veins per side, and 5–8 usually short and sometimes subacute, deeper lobes per side.</p>
