Discussion
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.
