--><p><i>Heterotheca jonesii</i> is known only from southwestern Utah. It forms dwarf cushions often partially buried in sand. Robust shoots are similar in general appearance to <i>H. villosa </i>var.<i> depressa</i>, which is stipitate-glandular and occurs in northwestern Wyoming. <i>H. jonesii</i> frequently occurs sympatrically with <i>H. villosa </i>var.<i> scabra</i>, a glandular, green-leaved and more robust taxon that is unlikely to be confused with it.</p>
