Fassou, N.Korotkova, Nersesian & Borsch comb. nov. ≡ Tunica pachygona Fisch. & C.A.Mey., Index Sem. Hort. Bot. Petropol. 4: 50. 1838 = Saponaria cretica L., Sp. Pl., ed. 2, 1: 584. 1762 ≡ Petrorhagia cretica (L.) P.W.Ball & Heywood in Bull. Brit. Mus. (Nat. Hist.), Bot. 3: 142. 1964. Type . not designated Lectotype. (designated by Davis in Notes Roy. Bot. Gard. Edinburgh 22: 164. 1957): locality, date and collector unknown, Herb. Linnaeus No. 580.4 (LINN!). Davis (1957) had pointed out the name Tunica cretica (L.) Fisch. & C.A.Mey. (basionym: Saponaria cretica L.) had been misapplied, whereas in fact the type of the name (the specimen in LINN) is an annual species that was later named Tunica pachygona Fisch. & C.A.Mey. Accordingly, the correct name in Dianthus would be D. pachygonus , the new combination published here because the epithet of Saponaria cretica is preoccupied in Dianthus by D. creticus Tausch. which is now treated as Dianthus fruticosus subsp. creticus (Tausch) Runemark.
