Pseudocydonia sinensis is morphologically intermediate between Cydonia and Chaenomeles, having the basally fused styles and 25 or fewer stamens of the former and the serrated leaves, glabrous fruits, and deciduous sepals of the latter. It has been placed in both those genera but is anomalous in both.
