摘要

The present paper presents a synopsis of 15 taxa of Agrostis from Ecuador as a contribution to an ongoing floristic project. Four species, Agrostis capillaris, A. idahoensis, A. jhanii, and A. meyenii, are newly reported from this country. Lectotypes for Agrostis conferta, A. conferta var. austropatagonica, A. nigritella, Aira anomala, Vilfa elegans, and V. fasciculata, are here designated. In addition, an epitype for Agrostis nigritella is designated, and Agrostis tolucensis var. andicola is here synonymized under A. tolucensis. This contribution to the systematics of Agrostis includes synonymy, iconography, geographic distribution and habitat, vernacular names, specimens examined, a key for the identification of taxa, and a comparative table based on morphological characters. Agrostis boyacensis, A. foliata, A. hyemalis, and A. jhanii are fully illustrated for the first time.
