|discussion=<p>As with most species of sect. <i>Mentzelia</i> first described by Urban and Gilg, the delimitation of <i>M. lindheimeri</i> has not been well understood. Phylogenetic results indicate that populations consistent with the types of <i>M. lindheimeri</i> and <i>M. texana</i> are part of a clade restricted to Gulf coastal areas from Florida to northeastern Mexico that also includes <i>M. floridana</i> and <i>M. gracilis</i>. Populations consistent with the <i>M. lindheimeri</i> and <i>M. texana</i> types overlap, and we treat <i>M. texana</i> as a synonym of the former. <i>Mentzelia lindheimeri</i> as treated here is restricted mostly to subtropical southeastern Texas. It is rare in trans-Pecos Texas, although we identified populations of <i>M. lindheimeri</i> in the Davis Mountains. Texas collections annotated as M. incisa Urban & Gilg by Thompson and Zavortink, which served as the basis for Texas reports of that species (for example, D. S. Correll and M. C. Johnston 1970; B. L. Turner et al. 2003) are treated here as <i>M. lindheimeri</i>.</p>
