Perennial, shrubs, trees, sometimes dioecious
Leaves generally opposite, simple, generally entire, generally deciduous; stipules 0
Inflorescence: cyme or racemes, generally umbel- or head-like, sometimes subtended by showy, petal-like bracts
Flower generally small, generally bisexual; calyx generally 4-lobed; petals 0 or 4(5), free; stamens generally as many as and alternate petals; ovary inferior, chambers 1–4, each 1-ovuled, style simple, stigma 1–4-lobed
Fruit: generally drupe or berry
Seeds generally 1–2
Genera in family: ± 12 genera, ± 100 species: especially n temp (also s tropical, subtropical). Cult as ornamental (Cornus, Aucuba ); some timber species. Genera diverse; many have been treated as constituting families, but trend is to treat Cornaceae broadly

Perennial, shrubs, trees
Leaves generally opposite or whorled, simple, generally deciduous; both ends generally tapered
Inflorescence small, head- or umbel-like, and surrounded by showy bracts (or cyme, large, open, lacking showy bracts)
