Due to the complicated evolutionary history in Pourthiaea, ninety-seven taxa have been described since 1784, and ninety-one of them are validly published taxa, five are naked names, and one is an invalid name. After a comprehensive and critical evaluation, 213 names have been published, including new combinations, new status, and new names; this may be due to the controversial taxonomic position of Pourthiaea in the apple tribe, Maleae. We herewith provide a taxonomic checklist of Pourthiaea for further taxonomic and evolutionary studies. We also lectotypify two taxa: Photinia amphidoxa var. stylosa and P. glabra var. fokienensis.
