The earlier publication of the name "Hemistepta [sic!] lyrata" by Bunge in Ledebour (Dorpater Jahrb. Litt. 1: 221. 1833) was not valid because the generic name had not been previously validly published (Vienna Code, Art. 43.1); nor were the generic and specific names simultaneously validated there (Art. 42.1: "Reference to an earlier description is not acceptable in place of a descriptio generico-specifica").

"Saussurea affinis Spreng." and "S. stricta Spreng." (Candolle, Prodr. 6: 540. 1838) both belong here but were not validly published because they were merely cited as synonyms of Aplotaxis carthamoides and A. multicaulis, respectively (Vienna Code, Art. 34.1(c)).
