摘要：
Youngia hangii T.Deng, D.G.Zhang, Qun Liu & Z.M.Li, sp. nov., a new species of Asteraceae, is described and illustrated. It was collected in Wufeng County, Hubei Province, Eastern Central China. Youngia hangii is morphologically most similar to Y. rubida, but can be easily distinguished from the latter by capitula with 8-10 florets and the hairy leaf surface. Phylogenetic analyses, based on the internal transcribed spacers (ITS) and one chloroplast marker (rps16), showed that Y. hangii and Y. rubida were sister species with good support. The results of both phylogenetic analysis and the morphological data support the specific rank of Y. hangii.
