Centaurea dissecta var. nigra Fiori

Centaurea dissecta var. nigra Fiori in Fiori & Bég., Fl. Italia 3 (2): 335. 1904. [April 1904] ≡ Centaurea parlatoris subsp. nigra (Fiori) Dostál, Bot. J. Linn. Soc. 71: 197. 1976. ≡ Centaurea ambigua subsp. nigra (Fiori) Pignatti, Giorn. Bot. Ital. 113 (5–6): 367. 1980. ≡ Centaurea delucae C. Guarino & Rampone, Bocconea 19: 85. 2006. Protologue citation. “ Abr. al M. Velino (Levier!), Gr. Sasso al Corno Grande (Levier!) ed a Pizzo Cefalone (Martelli!) e Camp. al M. Meta (Levier hb.!); reg. alp. ”. Lectotype (designated here). — [Italy, Abruzzo] Gran Sasso d’Italia. 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.
