--><p><i>Perityle gracilis</i> is known from southeastern <i>Nevada</i> in Meadow Valley Wash and in the Sheep Range. The only Arizona collection is the type (M. E. Jones in 1894, Kaibab Plateau). The 3-fid leaves with cuneate bases set <i>P. gracilis</i> apart from the similar <i>P. congesta</i> and <i>P. tenella</i>.</p>
