|discussion=<p>Often confused with <i>Artemisia rothrockii</i>, <i>A. spiciformis</i> has been recognized only recently as a widespread, high-elevation sagebrush of late-lying snowfields. Molecular analysis has not yet determined the degree to which this species intergrades with <i>A. cana </i>subsp.<i> viscidula</i> and <i>A. tridentata </i>subsp.<i> vaseyana</i>, the presumed parents of this putative hybrid. Because snow-field sagebrush produces fertile seeds and forms a stable community type, it is treated here as a distinct species.</p>
