|discussion=<p><i>Antennaria media</i> ranges from Arizona to Alaska; dioecious and gynoecious populations are encountered (R. J. Bayer and G. L. Stebbins 1987). The dioecious (sexual) populations are restricted primarily to California and Oregon (Bayer et al. 1990). The main distinction between <i>A. media</i> and <i>A. alpina</i> is flags on distal cauline leaves present in <i>A. alpina</i> and mostly absent in <i>A. media</i> (Bayer 1990d). Phyllaries of the pistillate plants in <i>A. alpina</i> tend to be acute; they are blunter in <i>A. media</i>. At some point, it may be preferable to follow W. L. Jepson ([1923–1925]) and some later authors and treat <i>A. media</i> as a subspecies of <i>A. alpina</i>. <i>Antennaria media</i> appears to be an autopolyploid derivative of <i>A. pulchella</i>; genes from <i>A. pulchella</i> may have introgressed into the <i>A. alpina</i> and <i>A. parvifolia</i> complexes indirectly through <i>A. media</i>.</p>
