Results from molecular phylogenetic investigations of Old and New World Artemisia species, and Beringian species in particular, have led to the reevaluation of certain taxa with broad disjunctions. One such taxon, Artemisia rupestris spp. woodii Neilson, is endemic to the southwestern Yukon Territory, Canada and represents the only North American occurrence of the Eurasian species A. rupestris. Based on a reexamination of specimens, molecular evidence, and geographic considerations, subspecies woodii is judged to be distinct from its Eurasian congeners and is elevated to specific rank as: Artemisia woodii (Neilson) C. Riggins, stat. nov. Phytologia 94(3): 301-304 (December 1, 2012).
