|discussion=<p><i>Trollius laxus</i> is closely related to the widespread, relatively common, western species <i>T. albiflorus</i>. Morphologically, the two are separated only by sepal color and the tendency for <i>T. albiflorus</i> to have slightly recurved follicular beaks and slightly smaller seeds.</p><!--
--><p><i>Trollius laxus</i> has been extirpated from central Pennsylvania. The species has been reported from Michigan; E. G. Voss (1972+, vol. 2) cast doubt on its occurrence there because no specimens to substantiate the reports have been found.</p><!--
--><p>The Cherokee used infusions prepared from the leaves and stems of <i>Trollius laxus</i> to treat thrash (D. E. Moerman 1986).</p>
