Status, distribution, and nomenclature of Northern Quillwort, <em>Isoetes septentrionalis</em> (Isoetaceae) in Canada
Bibliographic record
Abstract
The lycophyte Northern Quillwort (Isoetes septentrionalis D. F. Brunton, sp. nov.) is the northern component of the Riverbank Quillwort (I. riparia) complex. It is locally abundant in southeastern Ontario and southwestern Quebec and is also widely distributed in the northeastern United States. In Canada, it is largely confined to river and lake shores along post-glacial drainage outlets within the limits of the post-glacial Champlain Sea. It is frequently found in association with other Isoetes, especially Dodge’s Quillwort (I. × dodgei A. A. Eaton), its sterile hybrid with Spiny-spored Quillwort (I. echinospora Durieu). The Canadian population of I. septentrionalis appears to be stable. Although first proposed at species level over a century ago, the nomenclature of this taxon has remained unresolved. It is clarified in the present study, in which I. canadensis var. robbinsii is lectotypified.
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.
