Abstract

Due to the complicated evolutionary history in Pourthiaea, one hundred and two taxa have been described since 1784, and ninety-one of them are legally and validly published taxa, six are naked names, and five are superfluous names. After comprehensively and critically evaluating, 215 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 herein provided a taxonomic checklist of Pourthiaea for further taxonomic and evolutionary studies. We also lectotypified four taxa: Stranvaesia digyna, Photinia amphidoxa var. stylosa, P. glabra var. fokienensis, and Viburnum komarovii.
