Discussion | The name Townsendia condensata has been attributed to Parry ex D. C. Eaton or to D. C. Eaton. In February 1874 (Amer. Naturalist 8: 106), Parry used T. condensata provisionally and provided a diagnosis. In April that year, he used it as an accepted name and “validated” it by reference to his earlier diagnosis.

Of conservation concern. The type of Townsendia microcephala may prove to be conspecific with that of T. spathulata. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
