Abstract

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.
