Most people including Linnaeus, have mixed two or more species under one name. Recently, the typification and the identity of the names involved have been discussed by Verdcourt (Taxon 6: 231-233. 1957; Taxon 7: 84-85. 1958).

Since there is still confusion, a summary of the important names seems indicated.}, keywords = {GS, Ipomoea, nomenclature}, author = {Austin, D. F.} }
