|discussion=<p>Some plants, especially from Arizona, included here in <i>Gaillardia pinnatifida</i>, have mostly narrow, undivided leaf blades (mostly 3–8+ mm wide, villous to sparsely strigillose; <i></i>var.<i> linearis</i>) and intergrade with similar plants called <i>G. multiceps</i>, which have sparsely and minutely hispidulous or glabrate leaf blades.</p><!--
--><p>Plants from Utah with yellow disc corollas and densely gland-dotted leaves, included here in <i>Gaillardia pinnatifida</i>, have been recognized as G. flava.</p>
