Discussion
Four varieties of Photinia serratifolia are recorded in China; var. serratifolia occurs in the flora area and has leaf margins prominently serrate, entire only near the base (versus entire to shallowly and inconspicuously serrate in other varieties). Cultivars have been developed, however, differing in growth form, coloration, and leaf margins, and a formal identification to variety is problematic. Chinese photinia can grow larger than P. ×fraseri (‘red tip’) or Japanese photinia, and flowers appear before those of either.
