(Greek: Artemis, goddess of the hunt, noted herbalist, Queen of Anatolia) [Shultz 2006 FNANM 19:503-534; Shultz 2009 Syst Bot Monogr 89:1-131] Reports of Artemisia campestris L. subsp. pacifica (Nutt.) H.M. Hall & Clem. for California unconfirmed. Artemisia arbuscula var. thermopola Beetle not in California. Artemisia absinthium L. often cultivated, may persist, perhaps naturalizing in northeastern California. Recent studies place Sphaeromeria in the Artemisia clade (Garcia et al. 2011 Amer J Bot).
