Development of the flower and inflorescence of <i>Arum italicum</i> (Araceae)
Bibliographic record
Abstract
The spadix of Arum italicum Miller consists of two main parts: a clavate sterile portion (appendix) and a cylindroid fertile portion. In the fertile portion with both male and female zones, there are two zones of sterile flowers (bristles). The basal portion of bristles is surrounded by a verrucose structure consisting of a mass of tissular excrescences. During early stages of development, there is no free space between the different zones of the inflorescence. The elongation of the inflorescence axis is what eventually separates the different zones from each other. There are no atypical flowers that are morphologically intermediate between male and female flowers as is the case in other genera of Aroideae (e.g., Cercestis, Philodendron, Schismatoglottis). The structure of the bristles in the inflorescences of Arum does not correspond to any type of atypical flower (unisexual or bisexual) that has been analysed previously in the Araceae. From a developmental point of view, it is not possible to determine if the bristles correspond to aborted or modified female or male flowers. In the early stages of development, the stamens, staminodes, and appendix are covered by globular masses of extracellular calcium oxalate crystals.Key words: development, unisexual flowers, gradient, calcium oxalate crystals.

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.
