34b. Erigeron clokeyi Cronquist var. pinzliae G. L. Nesom, Sida. 21: 28. 2004.
Leaves uniformly hispidulous to hirsutulous (hairs spreading to spreading-arching, stiff). Cypselae 1.8–2 mm. 2n = 18.
Flowering Jun–Sep. Dry, rocky habitats, dry meadows, sometimes with sagebrush or mountain mahogany, common in treeless areas, often with yellow, bristlecone, or limber pine; 2200–3500 m; Calif., Nev., Utah.
Variety pinzliae is found in California, central Nevada, and west-central Utah. It apparently is discontinuously different from var. clokeyi and might be better treated at specific rank. Its relationship to Erigeron pygmaeus should be studied in such a consideration.
