Number of Occurrences81 - 300
Rank ReasonsKnown from southern Oregon, through California in the Sacramento Valley and coastal ranges, to northern Baja California, Mexico. Occurs in open sites in grassland as well as shrubland. The species has experienced a huge decline from historic levels and is threatened by development, agriculture, grazing, weeds, ORVs, and pigs.
Range Extent CommentsKnown from California, northern Baja California, Mexico, and found in southern Oregon in 2014 (Baldwin et al. 2012; Aldasoro et al. 2012; Element occurrence data in the NatureServe central database as of October 2018).
Occurrences CommentsIn California, 204 mapped occurrences, but 10 are confirmed extirpated and 69 are historical (CNDDB 2017). One extant occurrence in Oregon (Element occurrence data in the NatureServe central database as of October 2018). Approximately three specimens are mapped in Baja California, Mexico by Aldasoro et al. (2012).
Threat Impact CommentsThreats include development, agriculture, grazing, weeds, ORVs, and pigs (CNDDB 2017).
Ecology & Habitat
Habitat
Habitat is open sites, grassland, scrub, vertic clay, occasionally serpentine, less than 1200 m (Baldwin et al. 2012). In Kern County, California, usually growing in heavy soil, often in friable clay (dry bog) (Twisselmann 1967). In the Santa Barbara region, on serpentine on Figueroa Mountain, and in friable soil in Montgomery Potrero (Smith 1998).
