Discussion

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. Intergradation with subsp. detlingii occurs in Jackson County, Oregon.
