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.
