Heterotheca oregona (Nutt.) Shinners[FNA20, HC2, OFP]
Oregon goldenaster
Publication: Field & Lab. 19: 71. 1951.
Origin: Native
selected vouchers: WTU
Notes: Taxonomy follows Oregon Flora Project (OFP) and Sundberg and Chambers (2000) in combining all of the varieties: "We treat this as a polymorphic sp. Semple et al. (1988) reports vars. oregona and rudis from OR, but these vars. have overlapping ranges in CA and distinctions between them are relatively minor."
