|discussion=<p><i>Perityle intricata</i> has been treated as a subspecies or variety of <i>P. megalocephala</i>. Now that more collections are available for study, it is evident that this taxon should be treated as a species. The linear leaves, tightly aggregated heads on relatively short peduncles, and densely coarse-ciliate cypsela margins separate it from <i>P. megalocephala</i> with its broader leaves, loosely aggregated heads on longer peduncles, and short-hairy cypsela margins. Where the two distributions overlap (southern Nye County), they are reported to appear distinct in the field, with <i>P. intricata</i> occurring at lower elevations than <i>P. megalocephala</i>.</p>
