Prunus sunhangii: A new species of Prunus from central China

Abstract A new species of Rosaceae from Central China, Prunus sunhangii D. G. Zhang & T. Deng, sp. nov. , is described and illustrated. The new species is placed in Prunus subgenus Cerasus by flower and fruit characteristics. It is most similar to Prunus cerasoides , but differs by having longitudinally 2-lobed apical petals, an acuminate leaf apex, 17–25 stamens, white petals, dark black drupes, brown hypanthium, and different phenology. The phylogenetic placement of this species was assessed based on morphological and molecular data. Molecular analysis ( cp DNA + ITS) corroborated its placement in subgenus Cerasus , specifically P runus section Serrula .
