|discussion=<p><i>Euphorbia fendleri</i> is similar to <i>E. chaetocalyx</i> and may sometimes be confused with that species. Its prostrate to decumbent or ascending stems and small, ovate to orbiculate leaves distinguish it from <i>E. chaetocalyx</i>. Some authors have used the presence or absence and shape of the involucral gland appendages to help separate <i>E. fendleri</i> from <i>E. chaetocalyx</i>, but those characters appear highly variable and of little taxonomic utility; somewhat intermediate individuals occur in western Arizona, New Mexico, and Texas.</p>
