R. gigantea, R. moschata, and R. damascena were grouped into a cluster apart from the section Gallicanae because they appear to be monophyletic, whereas R. damascena was classified into the Section Gallicanae (Rehder, 1940). These species are more alike from morphological classification than from a molecular one , making them difficult to categorize.
