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.[https://www.biodiversitylibrary.org/page/9050472#page/601/mode/1up Gray, Asa. 1853.
