R. blanda also gives fertile vigorous hybrids with the diploid R. woodsii. An intergrading series between these forms makes it hard to classify the diploid roses of the northern Great Plains region. In herbaria these forms are usually called R. macounii, a species that is probably a definite ecotype of R. woodsii. Lunell's description of R. naiadum Lunell covers this hybrid, which resembles R. woodsii and may be used to designate intermediate forms.
