|discussion=<p>Variety megacephala is known mainly from the southern Sierra <i>Nevada</i> foothills and adjacent San Joaquin Valley and Transverse Ranges; it intergrades extensively with vars. lanosa and glabriuscula. A specimen cited by P. Stockwell (1940) from Bingen, Klickitat County, Washington (Suksdorf, May 1907) was not checked; it is either misidentified or from an introduction that did not persist.</p>
