|discussion=<p>Plants of <i>Senecio actinella</i> with relatively small proximal leaves similar to basal leaves and adaxial leaf faces early glabrate have been recognized as var. mogollonicus; the distinction is difficult to maintain. Receptacles in <i>Senecio actinella</i> are sometimes insect-infested.</p>
