--><p><i>Ivesia utahensis</i> is known from the Wasatch and adjacent Uinta Mountains in northern Utah. The species stands as the white-petaled counterpart to the yellow-petaled Sierran <i>I. lycopodioides</i>, possibly indicating a common ancestral stock that was once more continuous across the Great Basin.</p>
