--><p><i>Draba sobolifera</i> is related to, and sympatric with, <i>D. ramulosa</i>, and occasional sterile hybrids are encountered. There is no evidence of introgression and the two species are easily distinguished (see discussion of 90. <i>D. ramulosa</i>). <i>Draba sobolifera</i> is known from the Tushar Mountains in south-central Utah (Beaver and Piute counties).</p>
