Abstract

Studies in the genus Cortaderia (Poaceae) II. Cortaderia atacamensis, a new synonym of C. speciosa. 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.
