Abstract
The Crepidinae are the largest subtribe of the Cichorieae (Asteraceae). Debate remains over the circumscription and phylogeny of this subtribe, mainly due to its complex morphology and the poor phylogenetic signal provided by traditional Sanger sequencing markers. In this study, a well‐resolved phylogeny of the subtribe Crepidinae, consisting of seven highly supported clades, was obtained for the first time using nuclear data with a phylogenomics approach (Hyb‐Seq). Using this phylogeny along with other evidence, we propose a new taxonomic framework for the Crepidinae with seven lines and 29 genera, which merges subtribe Chondrillinae with the Crepidinae. We also describe a new monotypic genus, Qineryangia, that is characterized by broad involucres, loose imbricate phyllaries with wavy margins, and thick pappus bristles.
期刊介绍:
Journal of Systematics and Evolution (JSE, since 2008; formerly Acta Phytotaxonomica Sinica) is a plant-based international journal newly dedicated to the description and understanding of the biological diversity. It covers: description of new taxa, monographic revision, phylogenetics, molecular evolution and genome evolution, evolutionary developmental biology, evolutionary ecology, population biology, conservation biology, biogeography, paleobiology, evolutionary theories, and related subjects.
