Camissonia kernensis
Subspecies 2 (2 in the flora).
Camissonia kernensis occurs in sagebrush scrub, and Joshua-tree and pinyon-juniper woodlands at elevations of 700–1900 m in southern and central California and southern Nevada. The species is self-incompatible and is apparently pollinated by oligolectic bees of Andrena subg. Onagrandrena (P. H. Raven 1969); Raven subdivided the species into two intergrading subspecies.
