The Cornaceae or dogwood family is another family about whose taxonomy there is much disagreement. Apparently including from 1 to 6 (some say up to 15) genera and up to 60 species, its main member is Cornus. Several genera have been removed from the family and now placed in families of their own. According to some sources, genus Cornus has either been broken up into as many as 12 genera, or these genera have been lumped together under Cornus. The family contains mostly trees and shrubs, and is mainly concentrated in the northern temperate regions with some in tropical Asia, and a few in South America, Africa and Australia. It is closely related to the Hydrangeas. Leaves are usually simple and entire, the inflorescences are terminal with regular flowers sometimes subtended by showy white bracts, and fruits are drupaceous and fleshy. Many species are cultivated as ornamentals.
