When Lipschitz published the name Saussurea pulchra, he intended it to be a replacement name for his earlier "S. bella" (Lipschitz, Byull. Moskovsk. Obshch. Isp. Prir., Otd. Biol. 59(6): 83. 1954), which he evidently thought was illegitimate as a later homonym of S. bella Y. Ling (1949). However, because Lipschitz published "Hemisteptia bella" and "S. bella" simultaneously as alternative names, neither of them was validly published (Vienna Code, Art. 34.2). Lipschitz therefore inadvertently published S. pulchra as the name of a new species by reference to the Latin description of "H. bella" and "S. bella."
