Packera

Packera is a genus of about 64 species of plants in the composite family, Asteraceae. Its members were previously included in the genus Senecio (where they were called aureoid senecios by Asa Gray), but were divided out based on chromosome numbers, a variety of morphological characters, and molecular phylogeny.
