Notes: FNA19: "Crepis barbigera is recognized by its relatively tall stature, deeply pinnately lobed leaves, tomentulose stems, and phyllaries with coarse, green, eglandular setae. It is a complex of polyploid, apomictic forms, combining characteristics of C. atribarba, C. acuminata, and C. modocensis, from which the species is presumed to have been derived by intercrossing (E. B. Babcock 1947)."
