Nomenclatural clarifications and taxonomic circumscription of Schinus areira (Anacardiaceae) in Argentina

Schinus areira, an originally South American species, is naturalized in the northwest and west of Argentina, and has a great morphological affinity with S. molle, with which it shares part of its distribution range. Throughout their taxonomic history, both species have been treated as independent sp...

Schinus areira, an originally South American species, is naturalized in the northwest and west of Argentina, and has a great morphological affinity with S. molle, with which it shares part of its distribution range. Throughout their taxonomic history, both species have been treated as independent species, as a single species with two varieties or synonymized under the same taxon. The objective of this work was to review the taxonomy of S. areira, to redefine the diagnostic characters of the morphology that clearly differentiate it from S. molle in Argentina, and to perform nomenclatural clarifications. As a result, the specimens deposited in the LINN herbarium are discarded as possible types and the name of S. areira is lectotypified by means of an illustration. On the other hand, the following vegetative characters of S. areira were identified with taxonomic value: leaf dimorphism in the same branch, presence of wings in the rachis, and number of pairs and margin of leaflets. Additionally, a dichotomous key is presented to separate S. areira from S. molle. Schinus areira, especie originalmente sudamericana, se encuentra naturalizada en el noroeste y oeste de Argentina, y presenta una gran afinidad morfológica con S. molle con quien comparte parte de su rango de distribución. A lo largo de su historia taxonómica, ambas especies han sido tratadas como especies independientes, como una misma especie con dos variedades o sinonimizadas bajo el mismo taxón. El objetivo de este trabajo fue revisar la taxonomía de S. areira, redefinir los caracteres diagnósticos de la morfología que permitan diferenciarla claramente de S. molle en Argentina, y realizar clarificaciones nomenclaturales. Como resultado se descartan como posibles tipos los especímenes depositados en el herbario LINN y se lectotipifica el nombre de S. areira por medio de una ilustración. Por otro lado, se identificaron los siguientes caracteres vegetativos de S. areira con valor taxonómico: dimorfismo foliar en la misma rama, presencia de alas en el raquis y número de pares y margen de folíolos. Adicionalmente se presenta una clave dicotómica para separar S. areira de S. molle.
