|discussion=<p>Two varieties of <i>Mitella stauropetala</i> have been recognized. Plants from Oregon and Washington have been referred to var. stauropetala, characterized by hypanthium plus sepals often over 3 mm and petal blades with linear lobes. In northern Colorado, southeastern Idaho, eastern Utah, and Wyoming, var. stauropetala is replaced by var. stenopetala, with hypanthium plus sepals rarely over 3 mm and petal blades less deeply trifid (sometimes entire) and with broader lateral lobes. Variety stenopetala is morphologically similar in many respects to <i>M. trifida</i>. <i>Mitella trifida</i> and <i>M. stauropetala</i> require study to determine if plants referred to var. stenopetala are the result of hybridization or integradation between the two species.</p><!--
--><p>D. E. Soltis and P. S. Soltis (1986) found morphologic and allozymic evidence of fertile intergeneric hybrids between <i>Mitella stauropetala</i> and <i>Conimitella williamsii</i> in Wyoming. Data from cpDNA analysis suggest that <i>C. williamsii</i> is derived from within the <i>M. diversifolia</i>–<i>M. stauropetala</i>–<i>M. trifida</i> alliance (D. E. Soltis et al. 1990).</p>
