Discussion

Subspecies littoralis grows only in the coastal dunes of the central coast in Monterey and Santa Barbara counties. It intergrades with subsp. rigidus. It is not known if this subspecies is genetically distinct or if its distinguishing features are caused by the unusual habitat where the plants grow.
