-'''Cornaceae''' is a cosmopolitan family of [[flowering plants]] in the order '''[[Cornales]]'''. It contains approximately 85 species in two genera,<ref name="Christenhusz-Byng2016">{{cite journal |author1=Christenhusz, M. J. M. |author2=Byng, J.

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 [[inflorescence]]s or [[pseudanthium|pseudanthia]], and [[drupe|drupaceous]] fruits.<ref name=Kubitzki>Kubitzki, K.

Springer-Verlag, New York.</ref> In northern temperate areas, Cornaceae are well known from the dogwoods ''[[dogwood|Cornus]]''.
-The [[systematics]] of Cornaceae has been remarkably unsettled and controversial, and many genera have been added to it and removed from it over time. (One researcher called it a "dustbin."<ref name=Eyde1988>Eyde, R. H. (1988). Comprehending ''Cornus'' - puzzles and progress in the systematics of the dogwoods. ''Botanical Review'' '''54''', 233-351.</ref>) [[Molecular phylogenetics]] have clarified the relatedness of some associated genera, and at least nine genera that were previously included in Cornaceae have been eliminated from the order Cornales entirely,<ref name=Fan2003>Fan, C. Z., and Xiang, Q. Y. (2003). Phylogenetic analyses of Cornales based on 26S rRNA and combined 26S rDNA-matK-rbcL sequence data. ''American Journal of Botany'' '''90''', 1357-1372.</ref> but the circumscription of Cornaceae is still unclear. The [[Angiosperm Phylogeny Group]] usually defines Cornaceae as comprising the genera ''[[Cornus (genus)|Cornus]]'' and ''[[Alangium]]'' as well as five genera now separated into the family [[Nyssaceae]]. However, many of these genera are sometimes split off into their own families (e.g. [[Alangiaceae]]), and the usage remains inconsistent.<ref name=Fan2003 /><ref name=APGIII>{{Cite journal |last=Angiosperm Phylogeny Group |year=2009 |title=An update of the Angiosperm Phylogeny Group classification for the orders and families of flowering plants: APG III |journal=Botanical Journal of the Linnean Society |volume=161 |issue=2 |pages=105–121 |url=http://www3.interscience.wiley.com/journal/122630309/abstract | format= PDF |accessdate=2013-06-26 |doi=10.1111/j.1095-8339.2009.00996.x }}</ref>
