Centaurea deusta var. epirotica Bald., Nuovo Giorn. Bot. Ital. , n.s. 6 (2): 181–182. 1899.

Current name: Centaurea ptarmicifolia

Lectotype:—[ Greece] In lapidosis mobilibus summis, distr. Konitza , m. Smolika supra Kerasovo: 18 July 1896, A. Baldacci 243 ( WU 0071983 ), lectotype for Centaurea ptarmicifolia Halácsy ex Hayek nom. nov. (quod vide in Catalogue A).

Lectotype designated by Gamal-Eldin & Wagenitz (1991: 506).

The name C. ptarmicoides was mentioned by Halácsy (1902b) only in the index of his Conspectus Florae Graecae 2, most probably with the intention to replace the epithet epirotica, as on the indicated page he only gave a new combination of C. deusta var. epirotica Bald. for C. epirotica (Bald.) Halácsy. Hayek (1931) took C. ptarmicifolia Halácsy ex Hayek (as ptarmicaefolia) as replacement name. According to the decision of the special Committee for Spermatophyta C. epirota Halácsy and C. epirotica (Bald.) Halácsy are to be treated as homonyms ( Brummitt 2001) and thus C. ptarmicifolia Halácsy ex Hayek is the valid name at specific rank for C. epirotica (Bald.) Halácsy.
