Critical examination of herbarium specimens (including type materials) has shown that Stranvaesia microphylla described from Vietnam is conspecific with Photinia davidiana var. undulata (≡Stranvaesia davidiana var. undulata), which is widely distributed in China. Therefore, S. microphylla is reduced as a synonymy of P. davidiana var. undulata. Additionally, one new combination has been proposed and one lectotype has been designated here.
