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.
