|discussion=<p>Variety senilis grows in southern New Mexico and trans-Pecos Texas; it is rare in southern Arizona and across northern Mexico. The most hispid form of the species, <i></i>var.<i> senilis</i>, usually has numerous, spreading, large cilia along much or all of the leaf margins. The leaf margins are sometimes undulate, as in <i>Heterotheca sessiliflora </i>subsp.<i> sessiliflora</i>, and the two could be confused; the ranges do not overlap, however. The variety varies considerably in height and leaf size, and a number of collections are so reduced in size that they are easily mistaken for odd forms of <i>H. villosa </i>var.<i> minor</i> or <i>H. viscida</i>. Plants from southern Arizona often are similar to <i></i>var.<i> fulcrata</i>. When hair density is high, leaf faces are obscured and the plants appear light grayish green; they could be confused with <i>H. marginata</i>.</p>
