英文摘要	Photinia and its morphologically similar allies in Maleae (Rosaceae) consist of five currently recognized genera: Aronia, Heteromeles, Photinia, Pourthiaea, and Stranvaesia, and 68 species, distributed in Asia and North and Central America. Despite previous efforts to clarify relationships in this group, the generic delimitations have remained uncertain. Our goals were to reconstruct a robust phylogeny of Photinia and its close allies to test the monophyly of the currently recognized genera, especially Photinia and Stranvaesia, and the hybrid origin hypothesis of Photinia bodinieri. This study employs complete plastomes and the entire nuclear ribosomal DNA (nrDNA) repeats assembled from the genome skimming approach with a broad taxon sampling of 81 species in 30 genera of Rosaceae, especially Maleae. Based on three datasets, including the whole plastome, coding sequence, and nrDNA repeats, the results of maximum likelihood and Bayesian inference analyses showed that the previously circumscribed Stranvaesia and Photinia were each non-monophyletic. Six clades have been recovered herein within Photinia and its allied genera: Aronia, Heteromeles, Photinia s.s., Pourthiaea, Stranvaesia, and a new genus Phippsiomeles consisting of the Central American species formerly placed in Photinia. The strong conflicts between the plastome and nrDNA phylogenies of Phippsiomeles and Stranvaesia tomentosa suggest the possibility that they may have each originated involving hybridization events, while no incongruence among datasets was detected to support the hybrid origin of Photinia bodinieri. We provide 12 new combinations, to transfer eight taxa of the New World Photinia into Phippsiomeles and clarify the generic placements of several species of Photinia and Stranvaesia.
