The composition of the family Cornaceae has been a matter of much controversy among taxonomists for many years. Many sources, i.e. Flora of China treats the family as consisting of a single genus, Cornus, [1] while others include 17 or more genera. Cornus L. sensu lato consists of 55 species that are mostly trees and shrubs and rarely perennial herbs with woody rhizomes [2].

The USDA Plants Database includes Cornus, Aucuba, Campotheca, and Nyssa (tupelo) genera in the family [3].
