Heterotheca: from the Greek heteros, "different," and theke, "ovary," from the unlike achenes [small, dry, one-seeded fruit that does not open to release the seed] of the ray and disk florets
shevockii: after James R. Shevock (1950- ), a California botanist currently working for the National Park Service.
