Numerical taxonomy study on Prunus L.subgenus Cerasus (Mill.) A.Gray in China
Prunus L. subgenus Cerasus (Mill.) A.Gray is a controversial group in infra-subgeneric and species classification. Based on 30 morphological characters data
clustering analysis on 41 species was performed to infer the infra-subgeneric and species classification. The result shows that 41 species are divided into 11 groups
6 of them only contain 1 species
and others include 2 or more species7 species with controversies
Prunus conradinae Koehne
Prunus glabra (Pamp.) Koehne
Prunus henryi (C.K.Schneid.) Koehne
Prunus duclouxii Koehne
Prunus yunnanensis Franch
Prunus pseudocerasus Lindl. and Prunus pusilliflora Cardot are clustered into 1 group
indicating their related relationship; It would be appropriate to put them in one section or series. Prunus clarofolia C.K.Schneid.
Prunus polytricha Koehne
Prunus tatsienensis Batalin are in a group with a close distance in clustering analysis. The disciform glands in the margin of bracts are the distinguishing characters of Prunus tatsienensis to other 2 species
but the character was not found in the original literature and type specimen. And the densely villous of the Prunus polytricha is indistinguishable to other 2 species. The 3 species are proposed to be combined to 1 species.
