Phylogeny and taxonomic synopsis of Poa subgenus Pseudopoa (including Eremopoa and Lindbergella) (Poaceae, Poeae, Poinae)
Bibliographic record
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.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
