Systematics Lichter Marck, Isaac H [1], Freyman, William [2], Schneider, Adam C [1], Baldwin, Bruce [3]. Systematics of the rock daisies (subtribe Perityleae; Asteraceae). The members of the rock daisy tribe Perityleae (Asteraceae) are rock dwelling herbs and shrubs distributed throughout the western United States, Mexico, and South America. The tribe consists of four genera: the native Chilean monotypic genus Lycapsus, the genus Amauria, endemic to the Baja California Peninsula, the central Mexican genus Eutetras, the genus Pericome, native to southwestern North America, and the genus Perityle, which consists of 66 species native to arid regions and coastal habitats, as well as islands. Perityleae represents a striking example of hypothesized repeated amphitropical dispersals from North America to South America. While the monograph by Powell et al. (1974) has long served as a source for species and generic delimitation in this group, lack of a molecular phylogeny has impeded our ability to test biogeographic and putative taxonomic boundaries. We are using next generation sequencing methods, specifically genome skimming, to infer the first densely sampled molecular phylogeny of Perityleae genera. Our efforts are shedding new light on processes important for the evolutionary diversification of this and other species-rich plant clades in the Western US.
