|discussion=<p><i>Mentzelia mollis</i> is narrowly distributed in eastern Malheur County, Oregon, and western Owyhee County, Idaho, and disjunctly in the Black Rock Range of Humboldt County, <i>Nevada</i>. Recent phylogenetic studies support treatment of these disjunct populations as a single species (J. M. Brokaw and L. Hufford 2010b). In both ranges, <i>M. mollis</i> is predominantly limited to barren soils with high salinity. <i>Mentzelia mollis</i> is listed as endangered by the Oregon Department of Agriculture and is in the Center for Plant Conservation’s National Collection of Endangered Plants.</p>
