For the District of Lircay, we report a total of 46 species and one subspecies of the Poaceae family, grouped into 21genera, 11 tribes and 6 subfamilies. The genus Calamagrostis is the most diverse with 9 species, followed by Poa with 5 species. Also, Aciachne acicularis “paccupaccu”, Arundo donax “carrizo”, Cortaderia hieronymi and Ortachne erectifolia “iruichu” are new reports for the region of Huancavelica. Moreover, dichotomous keys are presented for the determination of species in the case a genus has more than one species. For each species, data on habitat, distribution, examined material and common name are included.

Palabras clave : Aciachne; Arundo; Calamagrostis; Cortaderia; Orthacne; Poa; taxonomy.
