The Biology of Canadian Weeds. 140. <i>Hesperis matronalis</i> L.
Bibliographic record
Abstract
The cruciferous weed Hesperis matronalis, dame's rocket (Brassicaceae), is an introduced Eurasian garden plant that began to escape shortly after its introduction to North America in the 19th century. It has gradually become naturalized across Canada and the United States, and has become invasive. It is not a major weed of crops, but is widespread in natural and conservation areas, particularly in thickets, open woodlands, forest margins and along streambanks, in parts of eastern and southern Ontario and western Quebec in Canada, and in New England and the midwest in the United States. In these habitats it can crowd out native vegetation and subsequently reduce biodiversity. Serving as an alternate host to a number of viruses, the species has the potential to infect cruciferous vegetable crops and garden plants. Despite its invasive potential, it continues to be sold at garden centres in both Canada and the United States. Key words: Hesperis matronalis, dame's-rocket, julienne des dames, weed biology, invasive alien, HEVMA
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
