|discussion=<p>Variety odontolepis occurs from the Coast Ranges and valleys of Oregon and the western Cascade Range south through the Siskiyou Area and the California North Coast Ranges to the San Francisco Bay region. California populations of <i></i>var.<i> odontolepis</i> usually have cream-colored corollas. Some Oregon populations have cream-colored corollas, and others, particularly in the Cascade Range, have purple corollas. The latter have been called subsp. oregonense. In other features these plants are very similar and have overlapping patterns of variation. Further study is needed to determine whether the purple-flowered plants are worthy of taxonomic recognition.</p><!--
--><p>There is much variation in the features of the phyllaries of <i></i>var.<i> odontolepis</i>. Four names, <i>Cirsium</i> callilepis, <i>C. remotifolium </i>var.<i> odontolepis</i>, <i>C. remotifolium</i> subsp. pseudocarlinoides, and C. amblylepis all have as their type location Mt. Tamalpais in Marin County, California, near the southern limit of the distribution of <i>C. remotifolium</i>. The type of <i></i>var.<i> odontolepis</i> has phyllary tips recurved or spreading. Other populations have narrow to broad phyllaries with tips erect to spreading, and variously erose to laciniate-toothed. Phyllary pubescence varies as well. Plants with phyllaries intermediate between those of <i></i>var.<i> odontolepis</i> and <i></i>var.<i> remotifolium</i>, and between those of <i></i>var.<i> odontolepis</i> and <i></i>var.<i> rivulare</i> are known.</p><!--
--><p>Interspecific hybridization is suspected to have contributed to the diversity of forms of <i></i>var.<i> odontolepis</i>. J. T. Howell (1949) speculated that the form named by Petrak as <i>Cirsium</i> amblylepis from Mt. Tamalpais may have originated through hybridization with <i>C. quercetorum</i>. Some specimens from central Oregon may be derivatives from hybridization with <i>C. edule</i>.</p>
