An order of flowering plants, division Magnoliophyta (Angiospermae), in the superordinal Asteridae group of Eudicotyledon. The order consists of 5 families (Cornaceae, Grubbiaceae, Hydrangeaceae, Hydrostachyaceae, and Loasaceae), approximately 50 genera, and about 600 species. The order is mostly characterized by opposite leaves and flowers with four or five perianth parts that usually grow from the top of the ovary (epigynous). The fruit is either a fleshy berry or dehiscent capsule. The various species of dogwoods (Cornus) and sour gum (Nyssa sylvatica, family Cornaceae) are well known.

• Family Cornaceae (dogwood family)
• Family Curtisiaceae (cape lancewood)
• Family Grubbiaceae (sillyberry family)
• Family Hydrangeaceae (hydrangea family)
• Family Hydrostachyaceae
• Family Loasaceae (stickleaf family)
