Rank Reasons
Known from San Bernardino County, California south to Baja California. There are approximately 39 sites in California and an unknown number in Baja California. Habitat is at high elevations in chaparral, lower montane coniferous forest, or pinyon and juniper woodland and substrate is rocky. Many sites are on public lands in California. Threats may include roads, vegetation clearing, and development.
Range Extent Comments
This species ranges from San Bernardino County, California south to Sierra San Pedro Mártir, Baja California (Flora of North America Editorial Committee 2010; Baldwin et al. 2012).
Occurrences Comments
In California, approximately 39 presumed extant occurrences (Element occurrence data in the NatureServe central database as of August 2015; CNDDB 2015). Unknown number in Baja California.
Threat Impact Comments
There is little development overlapping this high elevation species (Reiser, 1994). Although many are on public lands in California, there are still some threats including road/trail construction/maintenance, vegetation clearing, and development (Element occurrence data in the NatureServe central database as of August 2015; CNDDB 2015). Effects of fire uncertain.
Ecology & Habitat

Habitat

Dry rocky places, often slopes, sometimes among large rocks. Found in rocky openings in chaparral, pinyon-juniper woodland, openings and after fires in chaparral-oak woodlands, lower montane coniferous forest, open yellow pine forest, and big cone spruce communities, sometimes on sandstone substrates, at 900-2300 m (Flora of North America Editorial Committee 2010; Baldwin et al. 2012; CNPS 2015; Element occurrence data in the NatureServe central database as of August 2015).
