The biology of Canadian weeds. 122. <i>Lactuca serriola</i> L.
Bibliographic record
Abstract
Lactuca serriola (prickly lettuce, compass plant) is a winter or summer annual, introduced to Canada from Eurasia, and found in all provinces except Newfoundland. It occupies a variety of disturbed sites, and is becoming an increasing problem in crops grown with reduced t illage. Most seedlings emerge in autumn and form overwintering rosettes, with a smaller peak of emergence in spring. Flowering occurs from July through September. Seed production is proportional to stem height, and ranges up to 200 000 seeds per plant. The wind-dispersed seeds have no primary dormancy and form only a short-term seed bank (1 to 3 yr). Many populations in the western United States and southern Australia have developed resistance to Group 2 herbicides, which inhibit the enzyme acetolactate syn thase. Prickly lettuce is closely related to, and inter-fertile with, cultivated lettuce, Lactuca sativa L. Key words:

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.
