--><p><i>Perityle warnockii</i> is known only from the type locality in Val Verde County. The relationship of <i>P. warnockii</i> to <i>P. bisetosa</i> is evidenced by its similar though often reduced vegetative and floral morphology. The two species may have been derived separately from a common ancestor, perhaps a white-flowered member of sect. Pappothrix such as <i>P. vitreomontana</i>.</p>
