Discussion

Subspecies rosea occurs in the Inner Coast Ranges, Central Valley, and Sierra Nevada Foothills. C. T. Mason (1952) noted that populations in the northern part of the range tend to have white petals with pink veins, stamens, and pistils; those in the southern part of the range have petals with cream bases and yellow stamens and pistils.
