''Erigeron clokeyi'' is a North American species of flowering plant in the daisy family known by the common name Clokey's fleabane, or Clokey's daisy. ''Erigeron clokeyi''is native to the sage scrub of Nevada and far eastern California, and it can also be found in the talus of the eastern flank of Sierra Nevada.〔(Calflora taxon report, University of California, ''Erigeron clokeyi'' Cronq. Clokey's fleabane )〕 There are a few additional populations reported from Beaver County in Utah.〔(Biota of North America Program 2014 county distribution map )〕 ''Erigeron clokeyi''is a small perennial herb with leaves mostly around the base of the plant. The hairy, unbranching erect stems each hold an inflorescence of a single flower head which is about a centimeter (0.4 inches) wide. The head has a center of golden yellow disc florets and a fringe of sometimes as many as 55 very light to medium purple (occasionally white or pink) ray florets which are usually reflexed (bent away from the center).〔(Flora of North America, ''Erigeron clokeyi'' Cronquist, Brittonia. 6: 214. 1947.
