Hymenothrix wrightii
Hymenothrix wrightii, commonly known as Wright's hymenothrix or Wright's thimblehead, is a North American species of flowering plant in the daisy family. It grows in northwestern Mexico and the southwestern United States.
Hymenothrix wrightii is a perennial herb up to 60 cm tall. One plant produces 6-8 flower heads per stem, in a flat-topped array. Each head has 15-30 white, pink, or pale purple disc flowers but no ray flowers. The individual disc flowers are larger and showier than in many other species in the family.
