Discussion | Forms from the southern part of the range with cream-white tepals and pale anthers have been described as subsp. leucandrum. This species is closely related to E. revolutum and occasionally hybridizes with it where their ranges meet. In addition, E. citrinum and E. hendersonii are reported to hybridize with E. oregonum in the southern part of its range.

Erythronium multiscapideum is unusual among western species (and resembles some eastern species) in its tendency to reproduce vegetatively through the production of bulbels at the ends of stolons. It is similar in many respects to E. californicum and sometimes intergrades with it, resulting in occasional populations with the bulb characteristics of one species and the inflorescence branching pattern of the other.
