A Multilocus Phylogeny of Daphniphyllum (Daphniphyllaceae)

The monogeneric Daphniphyllaceae contain 36 taxa in the genus Daphniphyllum Blume that are endemic to Southeast Asia. is a morphologically homogeneous group of evergreen shrubs trees divided into three sections: Daphniphyllum, Lunata T. C. Huang, and Staminodia Hurusawa. While medicinal value has been explored many studies, understanding their evolutionary history infrageneric classification still limited. To test examine hypotheses proposed by previous taxonomic we reconstructed multilocus phylogenies sampling 55.6% (= 20/36) based on both chloroplast (psbA-trnH spacer trnL intron) nuclear ITS (ITS1, 5.8S rDNA, ITS2) regions. Our data do not support monophyly sections. results indicate some hybridization events might have occurred genus. Moreover, our D. glaucescens strict sense but broad sense. In addition, elevate ×lanyuense (T. Huang) M. S. Tang, H. Liu & Yuen P. Yang, stat. nov., from varietal rank species results. Two putative natural hybrids, teijsmannii Zoll. ex Teijsm. Binn., parental also revealed study. sum, shed new insights sectional scope relationships among Daphniphyllum.
