In "Note Sur plusiers espèces nouvelle de Rosiers des environs de Paris, et sure une nouvelle Méthode de decrire les espèces du genre Rosa,", Léman described 21 species of roses believed to occur naturally around Paris, of which Léman believes seven are new species. The descriptions are written in botanical Latin and are in the form of a key.
