Carpinus polyneura and C. dayongina are recognised as separate species in Flora of China. In this study, the results of an examination of literature, morphological comparison and phenetic clustering of nuclear ITS sequences suggest that C. dayongina is conspecific with C. polyneura. Thus, we propose reducing C. dayongina to a synonym of C. polyneura.
Keywords: Hornbeam; new synonym; taxonomy.
