Notes.

Although seeds are clearly visible on the image of the type specimen no description has been provided.

This species is related to Convolvulus canariensis and its allies from the Canary Islands and Madeira. It differs from Convolvulus canariensis in its near glabrous leaves and from Convolvulus massonii in its shorter sepals, smaller corolla and glabrous ovary. It is similar to Convolvulus volubilis but the leaves are oblong-elliptic, not linear lanceolate.
