--><p><i>Sclerocactus wrightiae</i> displays considerable morphologic variation, presumably due to introgression with <i>S. parviflorus</i>; however, it can usually be recognized by its noticeably fragrant flowers with pink to white tepals, and magenta staminal filaments. Although <i>S. wrightiae</i> generally has smaller stems and flowers and shorter spines than <i>S. parviflorus</i>, there are many exceptions.</p><!--
--><p><i>Sclerocactus wrightiae</i> is known to occur only near the Fremont River and San Rafael Swell in Utah. Exploitation by cactus collectors is partly responsible for its scarcity.</p><!--
--><p><i>Sclerocactus wrightiae</i> is in the Center for Plant Conservation’s National Collection of Endangered Plants.</p>
