La Valva and Sabato (Taxon 32: 110-114. 1983) have established that Ipomoea stolonifera (Cirillo) J. F. Gmelin, the name by which this species has long been known, is illegitimate, because it is based on the same type as the earlier Convolvulus sinuatus Petagna. Unfortunately, the latter epithet cannot by taken up in Ipomoea because of the later I. sinuata Ortega.
