Discussion

Varieties 2 (2 in the flora).

This species is sometimes confused with Fritillaria agrestis, which grows in heavier soil and has flowers with an unpleasant odor. Fritillaria roderickii is still recognized by some botanists, but it appears to be little more than a localized flower-color variant of F. biflora var. biflora, and is valued by horticulturists for this reason.
