w United States, Mexico, West Indies (Cuba, Hispaniola, Jamaica), Central America, e Asia, some species of both genera are cultivated and introduced widely.
Genera 2, species 27 (2 genera, 9 species in the flora).
Aucuba and Garrya are strikingly different, especially in their inflorescences, and Aucuba usually has been placed in Cornaceae or in Aucubaceae. However, plants from the two genera have many chemical similarities (A. Liston 2003) and can be readily intergrafted. B. Bremer et al. (2002) and Angiosperm Phylogeny Group (2003) united them in Garryaceae on the basis of molecular, chemical, and morphological evidence indicating that the two have a sister relationship. Aucubaceae was maintained as distinct from Garryaceae in the Flora of China (Xiang Q. Y. and D. E. Boufford 2005).
