Abstract
The valid publication date of Prunusdielsiana was found to be later than that of P.rufoides, which has been considered a synonym of P.dielsiana. Prunusdielsiana is therefore reduced to a synonym of P.rufoides, instead of the reverse. In addition, all previously named varieties of Prunusdielsiana, including var. abbreviata, var. conferta, and var. laxa, as well as P.carcharias are also listed as synonyms of P.rufoides in the present paper.
