|discussion=<p><i>Ancistrocarphus filagineus</i> occurs nearly throughout the Californian Floristic Province inland from the immediate coast; in the south, it stops at the western fringes of the Mojave and Sonoran deserts; farther north, it continues into the northern Great Basin and Columbia Plateau of Oregon, northern <i>Nevada</i>, and southwestern Idaho. The rigid whorl of inwardly-hooked staminate paleae holds tenaciously to clothing, skin, animal coats, even vehicle tires, providing an effective dispersal mechanism. It is surprising that it has not spread farther.</p><!--
--><p>Plants of populations farther inland, on drier sites and/or in deeper sandy soils, tend to be more compact with leaves shorter, more rounded, and indument denser and whitish. <i>Stylocline</i> filaginea <i></i>var.<i> depressa</i> has sometimes been misapplied to these unnamed forms. The two forms intermingle enough so as not to warrant formal taxonomic status.</p>
