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 Poa subg. Pseudopoa. Here we accept seven species, four subspecies and four varieties in Poa subg. Pseudopoa. Five new combinations are made: Poa attalica, P. diaphora var. alpina, P. diaphora var. songarica, P. nephelochloides and P. persica subsp. 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 Poa subg. Pseudopoa, synonymy for and a key to the taxa. Eight lectotypes are designated: Eragrostis barbeyi Post, Eremopoa nephelochloides Roshev., Glyceria taurica Steud., Nephelochloa tripolitana Boiss. & Blanche, Poa cilicensis Hance, Poa paradoxa Kar. & Kir., Poa persica var. alpina Boiss and Poa persica subsp. cypria Sam. Eremopoa medica is re-identified as a species of Puccinellia. © Lynn J.
