|discussion=<p><i>Layia hieracioides</i> occurs in the southern San Francisco Bay area, South Coast Ranges, and Western Transverse Ranges. Diploids and tetraploids are morphologically similar and reportedly geographically distinct, with diploids documented from the San Francisco Bay area and tetraploids (= L. paniculata) documented to the south. Natural, ± sterile hybrids between tetraploid plants and <i>L. glandulosa</i> have been documented from the Central Coast (B. D. Tanowitz and J. W. Adams 1986; R. F. Hoover 8369, UC).</p>
