|discussion=<p><i>Heterotheca pumila</i> grows in subalpine and alpine sites in Colorado, southeastern Utah (Lasalle Mountains), and southern Wyoming, where it is very rare. It is most similar to <i>H. villosa </i>var.<i> minor</i>, which in the range of sympatry has larger heads but smaller distal cauline leaves than are typically found in <i>H. pumila</i>. Reports of occurrence of <i>H. pumila</i> from Arizona and New Mexico are based on narrow-leaved plants of <i>H. fulcrata </i>var.<i> amplifolia</i> with small ovate-lanceolate bracts subtending the heads.</p>
