Comments: Habitat loss/degradation is the primary threat to this taxon. Known from San Diego County, California and Baja California, MX, the taxon is protected (in part) by the San Diego County Multiple Species Conservation Plan. However proposed amendments (2003) would allow a broader impact to the taxon's habitat. The species tends to occur in small scattered populations, although some populations are believed to have several hundred individuals, therefore fragmentation could play a role in population decline. There is much confusion over the taxonomy of this taxon, CNPS, the Jepson Manual and CAHP all consider this taxon to be indistinct from the much more common Solanum xanti, and therefore do not monitor or track.
