Notes: FNA19: "Subspecies laciniata occurs principally away from the coast, in interior valleys and hills, rarely reaching high elevations. The width of the outer phyllaries is a convenient way to separate it from subsp. leptosepala, with which it intergrades in the Klamath Mountains and at various sites east of the Cascade Range."
