Rupi della Traversa di Pizzo Cefalone , 16 August 1893 , U. Martelli s. n. (FI barcode FI 058572 [digital photo!], Suppl. material 1 : fig. S 4). Note. The name Centaurea dissecta var. nigra is legitimate even though it was published under the illegitimate C. dissecta Ten. (1812: LI), a later homonym of C. dissecta Hill (1762) (Art. 55.2 of the ICN). Fiori (1904) described C. dissecta var. nigra providing a short description, and quoting several herbarium samples and their collectors. We traced in FI some of the herbarium specimens cited by Fiori in the protologue: the duplicate specimens barcoded FI 058572 and FI 058582 are labeled “ Gran Sasso d’Italia, rupi della Traversa del Pizzo Cefalone, 16 agosto 1893 , U. Martelli ”; the specimen FI 058573 is labeled “ Gran Sasso d’Italia (Corno Grande) ad 26-2700 metri circa, 21 agosto 1879 , E. Levier ”. The morphology of these specimens is congruent with the protologue and with the current application of the name ( Pignatti et al. 2018 ; Bartolucci et al. 2024 ), and they can be safely considered as original material (Art. 9.4 of the ICN). We select here the herbarium specimen FI 058572, bearing the label “ Centaurea dissecta Ten. var. nigra Nob. ” made by Fiori, as the lectotype for the name C. dissecta var. nigra .
