|discussion=<p>Phylogenetic analyses (J. J. Schenk and L. Hufford 2011) recovered representative populations of <i>Mentzelia albescens</i> from Texas and South America in a monophyletic group. Phylogenetic placement of these populations among lineages in sect. Bartonia, as well as a lack of morphological differentiation among North American and South American populations, suggests a recent dispersal to South America. In the flora area, this species is native to central and western Texas, and introduced in Kansas, Missouri, and Oklahoma.</p>
