Discussion

Of conservation concern.

Subspecies congdonii is found in the South Coast Ranges and San Francisco Bay area. Molecular and morphologic studies have indicated that the southern and northern populations are evolutionarily distinct and may warrant treatment as distinct taxa (B. G. Baldwin, unpubl.).
