This work intends the delimitation of S. polygama, to describe S. talampaya (sp. nov.), previously mistaken...

Backgrounds and aims: Schinus polygama (Anacardiaceae) has historically been a taxon of intricate taxonomy. It was erroneously considered as a species widely distributed in the Southern Cone. This work intends the delimitation of S. polygama, to describe S. talampaya (sp. nov.), previously mistaken with S. polygama and S. longifolia, and to delimitate for both the geography and biogeography in Argentina.
M&M: We revised collections of national and international herbaria, as well as newly collected materials. We consulted the pertinent protologues and specialized taxonomic literature.
Results: Schinus polygama has been delimited from its closely related counterparts. We described a new species: Schinus talampaya. The new species can be distinguished by the shape and size of leaves, kind and length of the inflorescence, number of flowers per node, pedicel length, and geographic distribution. The study of the distribution confirmed that S. polygama is restricted to Mendoza province in Argentina, while S. talampaya inhabits the provinces of La Rioja and San Juan. We provide pictures, an illustration, a comparative table with morphological data, an identification key, and distribution maps. We discuss the taxonomic placement of the involved taxa among Schinus sections.
Conclusions: The evident morphological differences between S. polygama and S. talampaya allowed us to place the two species in two different sections: Duvaua and Pilifera, respectively. The new species is an important addition to sect. Pilifera from a morphological point of view, which implies the redefinition of the defining characteristics of the section, and thus the infragenerics systematics of Schinus. |

Introducción y objetivos: Históricamente Schinus polygama (Anacardiaceae), un taxón de taxonomía compleja y confusa, fue considerado de manera errónea como una especie con una muy amplia distribución en el Cono Sur americano. Este trabajo pretende delimitar S. polígama; describir una nueva especie, Schinus talampaya, confundida con S. polygama y S. longifolia y delimitar para ambas la distribución geográfica y biogeográfica en la Argentina. M&M: Se revisaron colecciones de herbarios nacionales e internacionales y nuevos ejemplares coleccionados. Se consultaron protólogos y trabajos taxonómicos específicos. Resultados: Se delimitó a S. polygama y se describe una nueva especie: Schinus talampaya, diferenciada por la forma y tamaño de las hojas, tipo y longitud de la inflorescencia, número de flores por nudo, longitud del pedicelo y su distribución geográfica. El análisis de la distribución geográfica permitió verificar que en la Argentina S. polygama está restringida a la provincia de Mendoza, mientras S. talampaya crece en las provincias de La Rioja y San Juan. Se proveen fotografías, una ilustración, una tabla morfológica comparativa, una clave para las especies afines y un mapa de distribución. Se discute la posición taxonómica de ambos taxones en las secciones del género. Conclusiones: Las evidentes diferencias morfológicas entre Schinus polygama y S. talampaya permitieron ubicar estas dos especies en diferentes secciones: Duvaua y Pilifera respectivamente. La nueva especie aporta a la variabilidad morfológica de la Sección Pilifera, lo que supone una redefinición de las características morfológicas del grupo y por ende su circunscripción taxonómica en el contexto de la sistemática infragenérica.
