Shoubiaonia yunnanensis is described here as a new genus and species of Amaryllidaceae from Yunnan Province, southwest China. Phylogenetic analyses based on DNA sequences of nuclear ribosomal ITS and three plastid regions ( matK , ndhF and rbcL ) strongly support Shoubiaonia as a member in the tribe Lycorideae of the Eurasian clade of Amaryllidaceae. However, morphologically S. yunnanensis is readily distinguished from the other genera in the Eurasian clade by its 2‐valved spathe, 3‐lobed stigma, ovary with two ovules per locule and silver black, subglobose seeds. The new genus is the second genus of the subfamily Amaryllidoideae distributed in natural habitat in China.
