Phylogeny and taxonomic synopsis of PoasubgenusPseudopoa (including Eremopoa and Lindbergella) (Poaceae, Poeae, Poinae).


ABSTRACT: Eremopoa is a small genus of annual grasses distributed from Egypt to western China. Phylogenetic analyses of plastid and nuclear ribosomal DNA show that Eremopoa species, together with the monotypic genus Lindbergella and a single species of Poa (P.speluncarum), are nested within the genus Poa, 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.diaphora var. alpina, P.diaphora var. songarica, P.nephelochloides and P.persicasubsp.multiradiata; P.millii is proposed as a replacement name for E.capillaris; and Poa sections Lindbergella and Speluncarae are proposed. We provide a diagnosis for Poasubg.Pseudopoa, synonymy for and a key to the taxa. Eight lectotypes are designated: Eragrostisbarbeyi Post, Eremopoanephelochloides Roshev., Glyceriataurica Steud., Nephelochloatripolitana Boiss. & Blanche, Poacilicensis Hance, Poaparadoxa Kar. & Kir., Poapersicavar.alpina Boiss and Poapersicasubsp.cypria Sam. Eremopoamedica is re-identified as a species of Puccinellia.
