Discussion | 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.) |
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.
