Publication: Phytologia. 49: 47. 1981.
Origin: Native
Herbarium search: CPNWH
Notes: FNA20: "Packera macounii is similar in overall morphology to P. cana. Leaves of P. macounii are narrower and frequently revolute. It is often cited as being collected on serpentine soils; it is not restricted to them. Senecio fastigiatus Nuttall (1840) is a later homonym of S. fastigiatus Schweinitz ex Elliott (1823), a name of uncertain application."
Chambers and Sundberg (2000) note this species is weakly separated from S. canus in sw OR
