Las magnolias de Cuba: Talauma – taxonomía y nomenclatura / Cuban magnolias: Talauma – taxonomy and nomenclature
Bibliographic record
Abstract
RESUMEN\nEn la actualidad se acepta mundialmente la reducción de todos los géneros de Magnolioideae (Magnoliaceae) a un único género Magnolia s.l. Al unificar las especies del género Talauma bajo Magnolia, las especie cubanas han sido arbitrariamente pasadas a la sinonimia de la única especie de este grupo que tenía un nombre válidamente publicado en la nueva concepción genérica: Magnolia minor (Urb.) Govaerts. En el presente trabajo se realiza la revisión taxonómica y nomenclatural del género Magnolia sect. Talauma en Cuba a partir de la revisión de la literatura publicada sobre estas especies, así como los protólogos, materiales tipos y otros materiales disponibles. Se describe la sección Talauma del género Magnolia en Cuba, se presenta una clave de identificación y se describen las tres especies que la conforman: Magnolia minor y dos nuevas combinaciones: Magnolia oblongifolia (León) Palmarola y Magnolia orbiculata (Britton & P. Wilson) Palmarola. Los materiales disponibles no permiten diferenciar Talauma ophiticola Bisse, de la especie más cercana: Magnolia oblongifolia. Se aportan elementos sobre la distribución, estado de conservación, nombre común y usos de las especies descritas.\n\n\nPalabras clave: Magnoliaceae, Talauma, Magnolia sect.

As species of genus Talauma were designated under the genus Magnolia, the Cuban species of the genus Talauma were mechanically considered synonyms of Magnolia minor (Urb.) Govaerts, the only Cuban Talauma with a valid name that fit into the new concept of the genus Magnolia. In this paper, we review the taxonomy and nomenclature of the genus Magnolia sect. Talauma in Cuba considering the literature, the protologue, type specimens and other specimens available. The section Talauma of the genus Magnolia in Cuba were described and the three Cuban species of this section: Magnolia minor and the two new combinations Magnolia oblongifolia (León) Palmarola and Magnolia orbiculata (Britton & P. Wilson) Palmarola were presented and also prepare an identification key of the three species. The herbarium specimens available do not allow differentiating Talauma ophiticola Bisse, from Magnolia oblongifolia. We also provide data on the distribution, conservation status, and ethnobotany of the three species.\n\n\nKeywords: Magnoliaceae, Talauma, Magnolia sect.

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.
