摘要：

This report provides a description of Primula sunhangii from the Shennongjia Forestry District, Hubei Province in Central China, which is categorized as a new species of the primrose family. Primula sunhangii is morphologically similar to P. involucrata Wall. ex Duby in terms of its simple umbel, efarinose, and prolonged bracts. However, P. sunhangii is distinguished by its glabrous sepal, short petiole (compare with blade) and cylindrical calyx and capsule. Molecular phylogenetic analysis based on nuclear and cpDNA genes demonstrates that P. sunhangii and P. involuctuta are closely related. Combining genetic and morphological data, the recognition of P. sunhangii as a unique new species is supported.
