|discussion=<p>The diploid <i>Trollius albiflorus</i> is isolated from the tetraploid <i>T. laxus</i> ecologically, geographically, and reproductively, although it often has been treated as a variety of the latter.</p><!--
--><p>Identities of specimens of <i>Trollius albiflorus</i> and the superficially similar <i>Anemone narcissiflora</i> subsp. zephyra in Colorado and Wyoming are sometimes confused. Close examination reveals a number of differences. The anemone has sepals yellow (not white), leaf blades and flowering stems pilose to villous (not glabrous), achenes (not follicles), and leaflike bracts subtending the pedicels and whorled (leaves alternate in <i>Trollius</i>).</p>
