Loasaceae is a family of 15–20 genera and about 200–260 species of flowering plants in the order Cornales, native to the Americas and Africa. Members of the family include annual, biennial and perennial herbaceous plants, and a few shrubs and small trees. Members of the subfamily Loasoideae are known to exhibit rapid thigmonastic stamen movement when pollinators are present.

Taxonomy

In the classification system of Dahlgren the Loasaceae were placed in the order Loasales in the superorder Loasiflorae (also called Loasanae). The Angiosperm Phylogeny Group system places them in the related order Cornales in the asterid clade.
