|discussion=<p>Following D. D. Keck (1960) and M. A. Lane (1985), <i>Gutierrezia californica</i> is treated here as a variable taxon that includes G. divergens. O. T. Solbrig (1965, 1970) considered <i>G. californica</i> to be a narrow endemic restricted to serpentine outcrops of the San Francisco Bay region, in which case the earliest name for the more widely distributed plants, including those of Mexico, is G. divergens Greene. Molecular evidence (Y. Suh and B. B. Simpson 1990) tentatively supports the recognition of the serpentine endemic; more detailed sampling would be needed for an objective decision. The morphologic differences are quantitative and overlapping. Intergrades between <i>G. californica</i> in the broad sense and <i>G. sarothrae</i> are said to occur in California (Lane 1993).</p>
