Hymenothrix wrightii, commonly known as Wright's hymenothrix[2] or Wright's thimblehead,[3] is a North American species of flowering plant in the daisy family. It grows in northwestern Mexico (Sonora, Chihuahua, Baja California) and the southwestern United States (western Texas , Arizona, New Mexico, far southern California ).[4][5]
Hymenothrix wrightii is a perennial herb up to 60 cm (2 feet) 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.[6][7][8]
