Correspondence and Comments Subsequent to Initial Analysis
Correspondence 1 31 Jul 2004 Interchange Feedback from Richard Moe, including e-mail from David Hollombe see Comment 1
Editorial Comments 1 Correspondence 1 indicates that Gnaphalium bicolor Bioletti is a later homonym of Gnaphalium bicolor Sch. Bip. (Bot. Zeit. iii. 171. 1845) and therefore illegitimate. In transferring the taxon to Pseudognaphalium, Anderberg published the new name Pseudognaphalium biolettii Anderb. (Op. Bot., 104: 147 (1991). This new name may have been the source of the use of "Pseudognaphalium bicolor (Bioletti) Anderb." by Kartesz, a mistake that has been picked up by ITIS. If the species is kept in Gnaphalium, a new combination would be required, using the epithet "biolettii" or, if any name of species rank had been placed in synonymy with Gnaphalium bicolor Bioletti before 1991, that epithet would have priority and would have to be used instead of "biolettii".
Correspondence 2 Treatment and author notes submitted for The Jepson Manual [Ed. 2] see Comment 2
Editorial Comments 2 Correspondence 2 indicates that for The Jepson Manual [Ed. 2] Gnaphalium bicolor Bioletti, illeg. is to be treated as a synonym of Pseudognaphalium biolettii Anderb..
Correspondence 3 14 Jan 2022 e-mail from John L. Strother, including forwarded email from Kanchi Gandhi see Comment 3
Editorial Comments 3 Correspondence 3 indicates that, according to Gandhi and as agreed to by Strother: Pseudognaphalium biolettii Anderb. was invalidly published in that "Anderberg did not provide the full bibliography for the replaced synonym"; according to Strother "Nesom (2002) might have inadvertently validated the name"; and the Kew staff confirmed that "POWO did not inadvertently validate the name before 2002"; so that the correct author citation is Pseudognaphalium biolettii Anderb. ex G. L. Nesom, Sida 20: 149. 2002. [Therefore, author citation corrected to Pseudognaphalium biolettii Anderb. ex G. L. Nesom, from Pseudognaphalium biolettii Anderb. previously in this Index, 19 Jan 2022.]
