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.

横断山脉的新属Qineryangia以及对Crepidinae(菊科)亚属系统发育的新认识
Crepidinae 是菊科(Cichorieae)中最大的亚科。主要由于其复杂的形态以及传统的 Sanger 测序标记所提供的系统发育信号较差,该亚支系的划分和系统发育仍存在争议。在本研究中,利用核数据和系统发生组学方法(Hyb-Seq),首次获得了由七个高度支持的支系组成的蝶形花亚科的系统发生。利用这一系统发育以及其他证据,我们提出了一个新的蝶形花科分类框架,包括 7 个支系和 29 个属,并将 Chondrillinae 亚支与蝶形花科合并。我们还描述了一个新的单型属--Qineryangia,其特点是总苞宽大,叶片松散覆瓦状,边缘呈波浪形,叶被刚毛粗大。
