A 1993-1997 study of the southern rubber boa (Charina bottae umbratica) in the San Bernardino Mountains identified the local population as dwarf forms. We identified four additional populations of northern rubber boa (C. b. bottae) that are also of this dwarf phenotype. All dwarf-morph populations cluster together in southern California. We suggest other dwarf populations occur in the same region but lack adequate samples for verification.
