Rudbeckia alpicola
Montane forests, shrublands, meadows, riverbanks. Flowering Jul–Aug. 1000–2100 m. BW, Lava. CA, WA. Native.
This species was cited by Cronquist (1994) as Rudbeckia occidentalis var. montana from the Elkhorn Range, Baker County, widely disjunct from the known range of that taxon in Colorado and Utah. These Oregon collections, and others from Steens Mountain, are here referred to R. alpicola, which according to Urbatsch and Cox (2006) is limited to the Wenatchee Mountains, Washington. However, R. alpicola had previously been reported from the Cascade Range in California as well (Ferris 1960). Additional collections are needed to clarify its distribution in Oregon.
