Thermogenesis in three <i>Philodendron </i>species (Araceae) of French Guiana
Bibliographic record
Abstract
Spadix temperature was measured in three species of Philodendron: P. acutatum Schott, P. pedatum (Hooker) Kunth, and P. solimoesense A. C. Smith. These species showed two different patterns of spadix temperature during their flowering cycle. In P. acutatum and P. pedatum (subgenus Philodendron), the spadix warmed up twice during the beginning of each flowering night with a temperature not significantly different from that of the ambient air between the two peaks. In P. solimoesense (subgenus Meconostigma), the spadix temperature rose to 14°C above that of the ambient air during the first night, then it progressively cooled down but remained 3-6°C above the ambient air temperature. We propose that the heat production and the spadix temperature patterns observed may reflect different physiological processes and have a taxonomic significance in the genus Philodendron.Key words: Araceae, flowering cycle, flower temperature, heating flower.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
