Discussion
Subspecies quadrivulnera is extremely widespread from Baja California in Mexico north through California, Oregon, and Washington to the islands of extreme southwestern British Columbia.
Subspecies quadrivulnera is diverse in petal color and color pattern but all of the populations have relatively small flowers that are primarily self-pollinated, usually with pollen in contact with the stigma at the time the flowers open.
