The taxon seems to be a new one, certainly for the British Isles and Ireland, and is similar to two previously described hybrids from Norfolk, Symphytum x norvicense (S. asperum x orientale) and Symphytum x uplandicum x caucasicum. Separation of these three taxa is discussed: all three are characterised by a combination of variegated red, blue, purple or white corolla bell, together with a calyx dissection to less than half way. This shallowly dissected calyx is the key to recognition of these three entities, which otherwise are easily overlooked as diminutive forms of Symphytum x uplandicum."

The saga of a pink bindweed (Calystegia) from Arthog, Meirioneth (v.c.48) with additional evidence / E. Ivor S. Rees in British & Irish Botany, vol. 1, n°4 (Année 2019)  

Public [article]  inBritish & Irish Botany > vol. 1, n°4 (Année 2019) . - pp. 342-346 Titre : The saga of a pink bindweed (Calystegia) from Arthog, Meirioneth (v.c.48) with additional evidence Type de document : texte imprimé Auteurs : E. Ivor S. Rees, Auteur Année de publication : 2019 Article en page(s) : pp. 342-346 Langues : Anglais (eng) Catégories : [Espèces (in biblio)] Calystegia Résumé : "For over five decades the identity of a pink-flowered bindweed (Calystegia) with a broadly rounded leaf sinus from the coast of West Wales has been subject to debate. Initially it was thought to have American origins, but it was subsequently treated as C. sepium subsp. spectabilis, a taxon thought to have genetic links to the Far East. Additional finds of other plants on western coasts of Britain and Ireland, and their similarities to a North American subspecies of C. sepium also having a broadly rounded leaf sinus now supports the original suggestion of inheritance from a trans-Atlantic drifted migrant."
