Revision as of 20:23, 16 December 2019
Leaf blades mostly 2.5–5 cm, margins pinnately toothed to pinnatifid. Involucres 6–8 m. Phyllary apices usually rounded, sometimes with weakly developed aristae. Florets 12–20. 2n = 12.
Phenology: Flowering (May–)Aug–Nov.
Habitat: Sandy soils, alkaline or salt flats, desert dunes, often with Saguaro-Prosopis-Larrea, Larrea, Atriplex, Yucca, or mixed shrubs
Elevation: (-15–)0–900(–1100) m
Distribution
Ariz., Calif., Nev., Utah, Mexico (Baja California, Sonora).
Discussion
For the most part, var. eremophila is geographically separate from var. acradenia. In southwestern Nevada many intergrades occur; in San Bernadino County, California, the two taxa appear to be contiguous with little or no intergradation. In the latter area, the taxa apparently are at different ploidy levels.
