Discussion

Plants lacking auricles on inner tepals are sometimes segregated as Erythronium howellii, Howell’s fawn-lily, but they do not appear to differ from typical E. citrinum in any other characters. Erythronium citrinum intergrades with E. californicum and E. hendersonii, occasional populations or individuals displaying intermediate or recombined characteristics. Such plants from the upper Scott River drainage in Trinity County, California, which may be the result of introgression with E. hendersonii, have been recognized as variety roderickii.
