|discussion=<p><i>Heterotheca viscida</i> grows in the mountains of southeastern Arizona, southwestern New Mexico, and trans-Pecos Texas. Plants from Texas generally have oblanceolate leaves and smaller heads and can be similar to forms of <i>H. fulcrata </i>var.<i> arizonica</i> and <i></i>var.<i> senilis</i>. The species typically blooms earlier in the season than <i>H. fulcrata</i>.</p>
