Summary:ABSTRACT A taxonomic revision of the genus Poa in Chile is given. Forty-two species, 5 subspecies and 5 varieties distributed in 4 subgenera, 15 sections and one informal group “Punapoa” are recognized. Synonyms, bibliographic references, notes on distribution and habitat, distinctive characters, and keys to species and subspecific taxa are provided for each species. The names Poa algida Trin., P. annua L. var. eriolepis E. Desv., P. ariguensis Steud., P. chilensis Trin., P. chrysantha Lindm., P. fuegiana (Hook.f.) Hack. var. involucrata Hack., P. maullinica Phil., and P. yaganica Speg. are lectotypified. A new combination and status is established for P. parviceps Hack. [P. scaberula Hook.f. subsp. parviceps (Hack.) Finot, Giussani & Soreng]. Poa dialystostachya is proposed as a new synonym of the endemic P. paposana.
