Don based Calonyction roxburghii on Ipomoea grandiflora Roxb. He also cited Ipomoea longiflora Willd. but by implication omitted its nomenclatural type as he made the new combination Quamoclit longiflora based effectively on the same name and treated it as a different species in the same volume. Steudel’s Ipomoea roxburghii can therefore be treated as a new combination based on Calonyction roxburghii G.Don , but it is a later homonym.
