Abstract
The floral volatile composition of four species of Vaccinium was profiled to asses the diversity of the floral chemistry within this genus. Flowers of Vaccinium angustifolium Aiton, Vaccinium varingiaefolium Miq., Vaccinium arboreum Marsh., and Vaccinium poasanum Donn. Sm. were sampled from three or more plants, and volatiles were collected and analyzed by gas chromatography – mass spectroscopy. A total of 45 volatile compounds were detected in the air (headspace) surrounding flowers including 40 from V. angustifolium, 34 for V. varingiaefolium, 37 for V. arboreum, and 17 for V. poasanum. Of the volatile compounds identified, 34 were terpenoids, 6 were benzoids and phenylpropanoids, 4 were aliphatics, and 1 was a miscellaneous cyclic compound. Terpenoids accounted for 98%, 80%, 76%, and 67% of the total volatiles for V. angustifolium, V. varingiaefolium, V. arboreum, and V. poasanum, respectively. The most abundant volatile compound emitted from the flowers of each species was α-pinene for V. angustifolium (23%) and V. arboreum (63%), methyl benzoate for V. varingiaefolium (18%), and ethyl benzene for V. poasanum (21%). Substantial variation was observed in the floral volatile composition of these four Vaccinium species, which may reflect their diverse ecological origins.

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.
