Abstract

fetched live from OpenAlex

Revue taxonomique du rhéophyte amazonien Schusterolejeunea Grolle (Lejeuneaceae: Cololejeuneinae), avec deux nouvelles combinaisons. Schusterolejeunea inundata (Spruce) Grolle est une espèce répandue, mais mal connue, limitée aux habitats riverains du bassin amazonien dans le nord de l'Amérique du Sud. Depuis sa description originale par Richard Spruce en 1884, les différences phénotypiques entre les populations ont convaincu l'auteur original de diviser le taxon en deux variétés. Un examen approfondi des spécimens de Schusterolejeunea Grolle provenant de régions disparates du bassin amazonien a fourni des preuves convaincantes de discontinuités entre la morphologie des feuilles, des lobules et du périanthe, soutenant une nouvelle proposition taxonomique. Dans la présente revue, le genre Schusterolejeunea considère deux espèces, S. inundata et l'espèce nouvellement élevée Schusterolejeunea saxorum (Spruce) A.M.Sierra & C.E.Zartman, stat. nov., comb. nov., qui diffère de S. inundata par ses feuilles oblongues, avec de grands lobules rectangulaires à oblongs, qui couvrent 1/3-2/3 du lobe de la feuille, et le périanthe à cinq carènes basses indistinctes. La variété Schusterolejeunea inundata var. fontinaloides (Spruce) A.M.Sierra & C.E.Zartman, comb. nov. est considérée comme un taxon distinct, se démarquant de S. inundata var. inundata par ses feuilles ovales et ses lobules sur la tige primaire triangulaire avec une carène plus longue s'étendant sur 6 à 12 cellules de long. Pour chaque taxon, nous présentons une description morphologique détaillée, la répartition géographique actuelle et des illustrations.

Not 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.
