Publication: Bot. Not. 128: 520. 1976.

Origin: Native

Herbarium search: CPNWH

Notes: FNA20": "Ecologically and morphologically, Packera paupercula is the most variable species of the genus in North America. Some "phases" have been treated as separate species, subspecies, varieties, forms, and races. Variation within P. paupercula hints at some interesting evolutionary relationships; characteristics used to separate taxa overlap. Much of the morphologic variation in this species may be due to hybridization and introgression. I do not recognize any of the infraspecific taxa that have been proposed."
