|discussion=<p><i>Antennaria racemosa</i> is characterized by adaxially glabrous basal leaves and open, racemiform to paniculiform arrays of heads (R. J. Bayer 1985b). The young leaves have a slight odor of citronella when crushed. <i>Antennaria racemosa</i> has a pivotal sexual genome of the Catipes group and has contributed to the origin of clones in the <i>A. howellii</i>, <i>A. parlinii</i>, and <i>A. rosea</i> polyploid agamic complexes (Bayer 1985, 1985b, 1990b).</p>
