Centaurea aspera Linnaeus (1753: 916)

Type: ─ Herb. Burser XV (2): 38 ( UPS-BURSER) [right-hand specimen] (lectotype designated here) ( Fig. 1 ) .

= Centaurea isnardii Linnaeus (1753: 916)

Type: ─[icon] in Isnard in Mém. Acad. Roy. Sci. Paris 1719: 164, t. 9. 1719 [illustration reproduced by Jarvis 2007: 119] (lectotype designated here) .

Centaurea isnardii was described by Linnaeus(1753:916) with a diagnosis“ Centaurea calycibus palmato-spinosis, foliis lyrato-dentatis hispidis subamplexicaulibus, floribus sessilibus terminalibus” and only one synonym, “Calcitrapoides procumbens, cichorii folio, flore purpurascente” from Isnard (1719: 164, t. 9). The indicated locality was “ Habitat in Europa australi?”. Isnard provided an excellent illustration and, as we have been unable to locate any further original material in any other Linnaean and Linnaean-linked herbaria (see Jarvis 2007: 400), it is the only extant original material eligible for the typification of the name (see Jarvis 2007: 119). The identity of Isnard’s plate confirms the status of C. isnardii as a taxonomic synonym of C. aspera .
