Morphocytological Characterization of Feverfew,<i>Tanacetum parthenium</i>(L.) Schultz Bip
Bibliographic record
Abstract
ABSTRACT A comprehensive, microscopic description of feverfew was developed for the accurate botanical identification of the plant (Tanacetum parthenium (L.) Schultz Bip.)- Floral morphologies of the cultivated varieties 'Double-flowered', 'White Stars' and 'White Pompom' were compared with the variety 'aureum' and a wild-type. Cytological observations of root tip squashes of all varieties confirmed the chromosome number as 2n = 18. The wild-type feverfew contained two distinct trichome types, a multicellular, uniseriate non-glandular trichome, with a long, flat and strap-like apical cell and a 10-celled, biseriate glandular trichome observed in large numbers on both the abaxial and adaxial leaf epidermis, in cuticular depressions on the abaxial surface of ray florets, and in vallecular grooves of seeds.

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.
