|discussion=<p>Of conservation concern.</p><!--
--><p>Variety cuspidata is localized in the greater San Francisco area, where it is rapidly becoming rare due to increased development. No collections of San Francisco spineflower have been made in Marin or Alameda counties since 1881. Populations may still be seen in San Mateo County, but their numbers have decreased greatly since the 1950s.</p>
