原始语种摘要: PREMISE OF THE STUDY:(#br)Hesperolinon (western flax; Linaceae) is endemic to the western United States, where it is notable for its high and geographically concentrated species diversity on serpentine‐derived soils and for its use as a model system in disease ecology. We used a phylogenetic framework to test a long‐standing hypothesis that Hesperolinon is a neoendemic radiation.(#br)METHODS:(#br)Five plastid and two ribosomal nuclear DNA gene regions were sampled from 105 populations of Hesperolinon , including all 13 recently recognized species across their known ranges. We used these data to generate population‐level phylogenies of Hesperolinon . We also generated a robustly sampled chronogram of Linaceae using an eight‐gene, 100‐taxon supermatrix calibrated using fossil Linum pollen...
