First record of Opuntia rioplatense (Cactaceae) for the Brazilian Flora
Bibliographic record
Abstract
The genus Opuntia Miller (1754) (Cactaceae Juss., Opuntioideae K.Schum., Opuntieae DC.) is native to the Americas, where is distributed from southern Argentina to Canada (Anderson 2001), and represents one of the largest genus of Cactaceae with ca. 150 species (see e.g., Stuppy 2002). Members of Opuntia shares a combination of peculiar morphological traits, including shrubs or trees with flattened photosynthetic stem shoots (cladodes), areoles with large smooth or retrorsely barbed spines and glochids, reduced and small caducous leaves , rotaceous diurnal flowers with inferior ovaries inner the pericarpels and stigma plurilobed, stamens with thigmonasty, reticulate semitectate pollen, and seeds covered by a sclerified funicular aril (Buxbaum 1953, Anderson 2001, Stuppy 2002, Hunt 2006, Majure & Puente 2014, Majure et al. 2017).
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.
