Notes

This is the perennial cornflower-blue Centaurea species with central flowering stem (not lateral as in C. pichleri) known as C. triumfetti in previous Greek floristic literature. As elucidated by Skokanová & al. (2009), C. triumfetti All. is a taxon confined to the Alps of SE France and NW Italy, hence phytogeographically classified as a W Alpine orophyte by Tison & de Foucault (2014: 421) and absent from other parts of Europe and the Mediterranean basin. In Greece and adjacent areas of SE Europe and SW Asia it is replaced by a species of the C. triumfetti group traditionally known as Centaurea axillaris Willd. (= C. triumfetti subsp. axillaris (Willd.) Stef. & T. Georgiev). Unfortunately, Willdenow’s name is illegitimate unless conserved with a conserved type as proposed by Skokanová & Koutecký (2018). If the proposal is not accepted, the well-established name would have to be abandoned and a new name would be required for European populations treated currently as Centaurea axillaris auct. or Cyanus axillaris auct. The younger synonym Centaurea cana Sm. seems appropriate for populations of Greece and Turkey but deserves if necessary a similar procedure of conservation by lectotypification since the type material from Ulu Dağ in NW Anatolia consists of a mixture of Centaurea pichleri Boiss. and an alpine form of the C. triumfetti group. Therefore Wagenitz (1975: 577) suggested that the name C. cana (≡ Cyanus canus (Sm.) Holub) should at best be dropped. We follow here the revised nomenclature, synonymy and epithet orthography adopted by Olšavska & al. (2011: 90–91): Allioni, in 1774, named Centaurea triumfetti after Giovanni Battista Trionfetti, alias Triumfetti (1658–1708), professor of botany and director of the Botanical Garden in Rome. In the original description Allioni used the epithet “triumfetti” as the appropriate genitive to the dedicatee’s latinized name Ioannes Baptista Triumfettus. The other often used orthographic variant “triumfettii” is formed by adding the appropriate genitive inflection (-i) to G. B. Trionfetti’s publicly established alias name. According to the rules of the Code of Botanical Nomenclature both epithets are correct, yet the original spelling “triumfetti” has priority.
