|discussion=<p><i>Artemisia bigelovii</i> of the southwestern deserts is easily confused in the field with <i>A. tridentata</i>, even though it is well distinguished ecologically and morphologically. Systematic placement within subg. Tridentatae remains problematic. Presence of “ray” florets (though rare) and vestigial spines on the pollen (R. P. Wodehouse 1935) suggest a relationship with groups ancestral to Tridentatae. The species also has the unusual characteristic of lignified trichomes (L. M. Shultz 1986b). Further research may help to determine proper placement; its affinities may be with members of subg. <i>Artemisia</i>.</p>
