--><p>Taxonomic opinions about the status and circumscription of the Nyssaceae have varied. <i>Nyssa</i> 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 <i>Nyssa</i> but still close to Cornaceae, follows R. H. Eyde (1966) and is supported by phylogenetic studies by Xiang et al. (2011).</p>
