Nyssa and the small eastern Asian genera Camptotheca Decaisne and Davidia Baillon sometimes have been included in an expanded Cornaceae, a view supported by earlier phylogenetic studies (Xiang Q. Y. et al. 1998). The narrower circumscription used here, with the family comprising only Camptotheca and Nyssa but still close to Cornaceae, follows R. H. Eyde (1966) and is supported by phylogenetic studies by Xiang et al. (2011).</p> |tables= |references={{Treatment/Reference |id=eyde1963a |text=Eyde, R. H. 1963.
