Acourtia is a genus of flowering plants in the family Asteraceae and was first described as a genus in 1830.[3][4][5] It includes desertpeonies, such as Acourtia nana (dwarf desertpeony) and Acourtia runcinata (featherleaf desertpeony).[6]

The genus name of Acourtia is in honour of Mary Elizabeth Catherine Gibbs à Court-Repington (1792–1878), an English noblewoman with botanical interests, who married Charles Ashe à Court-Repington.[7]

Plants in this genus are native to the Southwestern United States (from Arizona, California, Nevada, New Mexico, Utah to Texas) and Mesoamerica (in Belize, El Salvador, Guatemala, Honduras and Mexico).[8][9] They are diverse in appearance. The flowers are usually white, pink, or purple.[2][10][11] Their flower heads are usually composed of only disc florets, though some are long and look like ray florets.
