Roemeria sicula (Guss.) Galasso, Banfi, L. Saez & Bartolucci comb. nov.

Papaver siculum ≡ Papaver siculum Guss., Fl. Sicul. Syn. 2(1): 6 (1843-1844) ≡ Papaver hybridum subsp. siculum (Guss.) Arcang., Comp. Fl. Ital. [Arcangeli]: 24 (1882) ≡ Papaver hybridum var. siculum (Guss.) Raimondo & Spadaro, Bocconea 20: 12 (2007).

Papaver siculum Ind. Loc.: "Inter segetes; nel fiume fra S. Giuseppe e Castellammare (Gasparrini); Palermo ".

Papaver siculum Type (lectotype, designated here): [Italy, Sicily]. Nel fiume da S. Giuseppe a Castellammare, s.d., Gasparrini s.n. (NAP barcode NAP0001798 [digital photo!]).

Papaver hybridum = Papaver hybridum L., Sp. Pl. 1: 506 (1753), non Roemeria hybrida (L.) DC., Syst. Nat. 2: 92 (1821)

Papaver hybridum Type (lectotype designated by Aghababyan and Raimondo 2011: 1475): Herb. Burser IX: 56 (UPS).

Papaver hispidum = Papaver hispidum Lam., Fl. Franç. (Lamarck) 3: 174 (1779), nom. illeg. ≡ Roemeria hispida Stace, New J. Bot. 7(1): 9 (2017)

According to recent molecular phylogenetic studies, the species belonging to Papaver sect. Argemonidium Spach have been transferred to the genus Roemeria Medik. ( Banfi et al. 2022). The name Roemeria hispida proposed by Stace (2017) should be treated as a replacement name (Art. 58.1 of the ICN, Turland et al. 2018) and not as a new combination, because it is based on P. hispidum Lam., an illegitimate superfluous name for P. hybridum L. (Arts. 52.1 and 52.2 of the ICN). The final epithet " hybrida " is already taken in Roemeria , so the next earliest legitimate name at species rank is P. siculum Guss., on which the new combination here proposed is based. The name P. siculum is also lectotypified here based on a specimen kept in NAP, where Gussone’s main collection is housed. The lectotype morphologically matches the description by Gussone (1844) and agrees with the current application of the name P. hybridum .
