Rosa x arnoldiana Sarg. (1919) applies to crosses between R. rugosa and hybrid perpetuals, which Sargent classified as R. borbonia Desportes. The "specification" of Bourbons and Hybrid Perpetuals has been subsquently rejected. At most, R. x arnoldiana appears to be a synonym of 'Dawson's Hybrid Rugosa,' and does not represent a hybrid of two species at all. See References.]
