Nomenclature and taxonomic identities of Prunus zappeyana and P. zappeyana var. subsimplex (Rosaceae)

The original specimens of both Prunus zappeyana and P. zappeyana var. subsimplex were found to belong to more than one taxon. In addition, P. zappeyana var. subsimplex was found to be invalid because, when the name was published, two separate descriptions were given to two cited collections, but not to the taxon, making the name unaccompanied with a description or diagnosis of this taxon (Art. 38.1 (a)). Therefore, a lectotype of P. zappeyana was designated under Art. 9.11 of ICN, by which P. zappeyana was placed in the synonymy of P. veitchii.
