Abstract:
... Understanding species level relationships is a central goal in systematic botany; however, complexes of closely related and morphologically similar species often pose considerable challenges to that goal. The North American west is home to many notable genera that notoriously have difficult species complexes (e.g. Astragalus, Eriogonum, Penstemon). Mentzelia section Bartonia (Loasaceae), another e ...
