|discussion=<p>I have seen limited material of var. lemhiensis, and all the differences given by R. C. Rollins (1993) to separate it from <i></i></i>var.<i><i> perplexa</i> (e.g., style and pedicel length, density of indumentum) are quantitative characters that show continuous, uncorrelated variation. <i>Sandbergia perplexa</i> is known from counties in Idaho (Adams, Butte, Custer, Idaho, Lemhi, Valley), Montana (Beaverhead), and Washington (Douglas).</p>
