|discussion=<p>Morphological differences among <i>Croton heptalon</i> and its multifid-styled relatives in sect. Heptallon, especially <i>C. capitatus</i> and <i>C. lindheimeri</i>, can be quite subtle. In general, <i>C. heptalon</i> can be distinguished from <i>C. capitatus</i> by its more elongate pistillate part of the inflorescence, non-recurving sepal tips in the pistillate flowers, and more cordate leaf bases on larger basal leaves. Whitish pubescence on its young growth and styles that branch once into four terminal segments distinguish <i>C. heptalon</i> from <i>C. lindheimeri</i>.</p><!--
--><p><i>Croton</i> muelleri J. M. Coulter, which is an illegitimate name, pertains here.</p>
