--><p>The leaves of <i></i>var.<i> sionis</i> tend to be narrower and more deeply lobed than those of <i></i>var.<i> trilobatus</i>; morphologic intermediacy makes these plants hard to separate even at varietal rank. Differences in habitat and an essentially allopatric distribution, however, suggest that two evolutionary entities are present.</p>
