Oreomecon alpina subsp. suaveolens (P.Fourn.) Banfi ,

Bartolucci, J.- M.Tison & Galasso, comb. nov.

bas.: Papaver pyrenaicum subsp. suaveolens P.Fourn., Quatre Fl. France 4: 372. 1936 ≡ Papaver alpinum subsp. suaveolens (P.Fourn.) Rändel ≡ Papaver alpinum subsp. suaveolens (P.Fourn.) O.Bolòs & Vigo , isonym

Type (lectotype, designated here): Papaver alpinum? Lin. sommets elevés, fentes des rochers. Mail du Crystal, Cambredases, Pic de Midy , Erezlidtz, Houle Marboré, Lapeyrouse s.n [before 1813] ( TLM [digital image!], bottom-right individual, Fig. 1 ) [herbarium acronyms follow Index Herbariorum, 2021]

= ? Argemone pyrenaica L. ≡ Papaver pyrenaicum ( L.) Willd.

Note. Papaver pyrenaicum ( L.) Willd. is based on Argemone pyrenaica L. quoted from Pyrenees (“Habitat in Pyrenaeis. Tournefort”). Since only subsp. suaveolens does exist in this region, the epithet pyrenaicum should be prioritary, if its type indeed comes from Pyrenees and belongs to P. sect. Meconella , but it is not designated (Jarvis, 2007). We were not able to trace in P the Tournefort’s original material, but, anyway, the presence of such a collection in this herbarium is very uncertain. Only a careful investigation in situ at P and a conservation process (likely with neotypification) will allow to fix the sense of P. pyrenaicum . However, in conformity with predominant usage of a name, a proposal for rejection would be easier and more useful.

– Papaver suaveolens sensu Lapeyr.

– Papaver lapeyrouseanum Gutermann , nom. inval. (published as lapeyrousianum to be corrected in lapeyrouseanum according to Art. 60.9 of the ICN)

= Papaver lapeyrouseanum Gutermann ex Greuter & Burdet (published as lapeyrousianum to be corrected in lapeyrouseanum according to Art. 60.9 of the ICN) ≡ Papaver alpinum subsp. lapeyrouseanum (Gutermann ex Greuter & Burdet) Kerguélen

= Papaver suaveolens var. endressii Asch. ≡ Papaver lapeyrouseanum subsp. endressii (Asch.) Greuter & Burdet

Note. Papaver suaveolens Lapeyr. (Lapeyrouse, 1818) is illegitimate because the author listed among the synonyms P. aurantiacum Loisel. , a species described from Mont Ventoux (Loiseleur-Deslongchamps, 1809) that automatically typifies the name of Lapeyrouse (Art. 7.5 of the ICN). Gutermann (Gutermann et al., 1974) planned to remedy by creating a replacement name (Art. 6.11 of the ICN), P. lapeyrouseanum Gutermann. However , the latter is actually the name of a new species (Art. 58.1 of the ICN) not validly published as the type was not indicated (Art. 40.1 of the ICN). Finally, Greuter & Burdet (Greuter, 1981) validly published the name P. lapeyrouseanum Gutermann ex Greuter & Burdet. However , when Fournier (1936) re-used the final epithet at a different rank for a taxon restricted to the Pyrenees only, implicitly excluded P. aurantiacum (from Mont Ventoux). So P. pyrenaicum subsp. suaveolens P.Fourn. is not to be treated as a replacement name with the same type as P. suaveolens , but as the name of a new taxon with a different type (Art. 58.1 of the ICN), accompanied by an indirect reference to the previously and effectively published Latin description by Lapeyrouse (Arts. 39.1, 38.13 and 38.14 Ex. 22 of the ICN). According to Art. 7.8 of the ICN, a name of a new taxon validly published solely by reference to a previously and effectively published description or diagnosis is to be typified by an element selected from the entire context of the validating description or diagnosis. We traced in TLM two herbarium specimens collected by Lapeyrouse in several Pyrenean localities. These specimens were collected surely before 1813 as the informations on the labels were reported exactly in Lapeyrouse (1813).
