|discussion=<p><i>Mentzelia veatchiana</i> is the most common and widely distributed hexaploid species in sect. Trachyphytum. It exhibits considerable morphological variation and can be difficult to distinguish from <i>M. montana</i> in northern California. Like the larger-flowered <i>M. pectinata</i>, <i>M. veatchiana</i> has interfertile populations with petal colors ranging from orange to yellow (J. E. Zavortink 1966). When bearing orange petals, <i>M. veatchiana</i> is easily distinguished from other species. Reports of <i>M. veatchiana</i> from Utah are based on specimens treated here as <i>M. montana</i>.</p>
