|discussion=<p>Glandular plants of Thalictrum dioicum have often been misidentified as T. revolutum despite important differences, especially the leaflets having crenate versus entire lobe margins, respectively. The stamens in both T. dioicum and T. revolutum are pendulous.</p><!--
--><p>Native Americans used roots of Thalictrum dioicum in various preparations to treat diarrhea and vomiting and for heart palpitations (D. E. Moerman 1986).</p>
