          Abstract

          En esta contribución a la sistemática del género Cortaderia se propone la sinonimización de C. atacamensis y C. speciosa. Hasta ahora el binomio Cortaderia atacamensis ha sido considerado un sinónimo de C. jubata. Sin embargo, el estudio de los ejemplares tipo y de las descripciones originales, complementado con estudios de campo, demostraron que C. atacamensis es un sinónimo de C. speciosa (una especie nativa de las regiones desérticas desde Perú hasta el norte de la Argentina y Chile), distinta de C. jubata (una especie típica de los bosques andinos desde Colombia hasta el norte de la Argentina). Se presentan una caracterización morfológica y una clave para separar ambas especies.

          Translated abstract

          In this contribution to the systematics of the genus Cortaderia the synonymization of C. atacamensis and C. speciosa is proposed. Until now the binomial Cortaderia atacamensis has been considered a synonym of C. jubata. Nevertheless, the study of the type specimens and original descriptions, complemented with field studies, demonstrated that C. atacamensis is a synonym of C. speciosa (a species native to the desertic regions from Peru to northern Argentina and Chile), rather than of C. jubata (a species typical of the Andean forests from Colombia to northern Argentina). A morphological characterization and a key to separate the two species are provided.
