Discussion | Crepis elegans is recognized by its loose, cespitose habit, relatively small spatulate leaves, blackish green, glabrous phyllaries, and beaked cypselae. It is thought to be closely related to C. nana, and, possibly, derived from it (E. B. Babcock 1947). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
