Notes



Known only from dunes in Eureka and Panamint Valleys, within Death Valley NP. Habitat previously degraded by vehicle traffic; populations recovering well, but still threatened by vehicle trespass, foot traffic, and recreation, and possibly by non-native Russian thistle. Recovery plan has been completed by BLM. See Leaflets of Western Botany 8(1):22 (1956) for original description, Memoirs of the New York Botanical Garden 13:952-953 (1964) for taxonomic treatment, and Biological Conservation 46:217-242 (1988) for population biology.
