--><p><i>Perityle dissecta</i> occurs in southern Brewster and Presidio counties. It and <i>P. lemmonii</i> have been considered conspecific by some taxonomists because of similarities in gross leaf morphology. The differences in phyllaries, disc corollas, and pappus bristles, as well as distinct distributions, support recognizing them as separate species.</p>
