Abstract:
An updated catalogue and nomenclator of the grasses in the Poaceae family is presented for El Salvador. The work is based on bibliographic and herbarium research and on recent collecting trips carried out by the first author in El Salvador between 2014-2017. The catalogue reports 371 species, 10 infraspecific names, and 381 total taxa. Herbarium vouchers, bibliographic reports, and distributions within El Salvador are reported for each accepted taxon. Synonyms are included in the list and these are all directed to the accepted name. A new combination, Rugoloa pilosa var. lancifolia (Griseb.) Baldini & Menjívar, comb. nov., is provided.
