英文摘要	Background and Aims: The genus Jarava consists of 30-32 species distributed from Mexico to South America. Stipa and Jarava were not well delimited for many years, even Stipa disticha was considered as a synonym of J. pachypus in taxonomic treatments and catalogs. The objective of this study is to delimit the morphological characters, make the new taxonomic combination and mention the distribution for both species. Methods: Field collected material was gathered in 2020-2021. In addition, herbarium collections (CUZ, HSP, HUSA and USM) have been examined. To diagnose the species, taxonomic revisions, protologues and analysis of digitized types were utilized. For each species, morphological descriptions, images and a distribution map were made. Diagnostic characters of the Jarava species present in Peru were used to elaborate a dichotomous key. Key results: Javara disticha is presented as a new combination. The form of branching of the culms, width of the lower glumes, and size and indumentum of the anthoecia are the main taxonomic characters that allow the delimitation between J. disticha and J. pachypus. The two species are distributed in the lomas formations of southern Peru. Conclusions: With the new combination, six species of Jarava are present in Peru. Jarava disticha is distributed in the departments of Ica and Arequipa, while J. pachypus is endemic to southern Arequipa.
