Camissonia megalantha

Description

Generally dry, open, loose soils on sandy to gravelly flats, slopes, or scree, sometimes in outcrop crevices, derived mainly from whitish to brownish volcanic tuff or tuffaceous sedimentary deposits, usually in places with frequent light disturbance such as shifting slopes, washes, roadsides (or in lightly used road beds), or on older recovering disturbances, mainly in salt desert shrub communities. Surveys have been extensive and are largely complete, but a few undocumented occurrences may remain.
