Cohen and Schenk (2021) Data from: Investigating phylogenetic placement and species-level relationships in a recent radiation of Mentzelia section Bartonia (Loasaceae) from the Mojave Desert

Dylan Cohen & John Schenk
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) is a recently evolved and diverse clade that occurs across the North American west. Phylogenetic studies have resolved many relationships, but the relationships within...
