Cornaceae Cornaceae is a cosmopolitan family of flowering plants in the order Cornales. It contains approximately 85 species in two genera, "Alangium" and "Cornus". They are mostly trees and shrubs, which may be deciduous or evergreen, although a few species are perennial herbs. Members of the family usually have opposite or alternate simple leaves, four- or five-parted flowers clustered in inflorescences or pseudanthia, and drupaceous fruits. In northern temperate areas, Cornaceae are well known from the dogwoods "Cornus".
