Taxonomy and biogeography of Diapensia(Diapensiaceae) based on chloroplast genome data
Abstract Diapensia L. is the second largest genus of Diapensiaceae. The taxonomic treatment within Diapensia and relationships within Diapensiaceae have been disputed. Chloroplast genome sequence data have proved to be useful for plant phylogenetic analyses and species delimitation. In this study, w...
