Abstract

Eremopoais a small genus of annual grasses distributed from Egypt to western China. Phylogenetic analyses of plastid and nuclear ribosomal DNA show thatEremopoaspecies, together with the monotypic genusLindbergellaand a single species ofPoa(P.speluncarum), are nested within the genusPoa, in a clade that we accept as Poasubg.Pseudopoa. Here we accept seven species, four subspecies and four varieties in Poasubg.Pseudopoa. Five new combinations are made:Poaattalica, P.diaphoravar.alpina, P.diaphoravar.songarica, P.nephelochloidesand P.persicasubsp.multiradiata;P.milliiis proposed as a replacement name forE.capillaris; andPoasectionsLindbergellaandSpeluncaraeare proposed. We provide a diagnosis for Poasubg.Pseudopoa, synonymy for and a key to the taxa. Eight lectotypes are designated:EragrostisbarbeyiPost,EremopoanephelochloidesRoshev.,GlyceriatauricaSteud.,NephelochloatripolitanaBoiss. & Blanche,PoacilicensisHance,PoaparadoxaKar. & Kir., Poapersicavar.alpina Boiss and Poapersicasubsp.cypria Sam.Eremopoamedicais re-identified as a species ofPuccinellia.
