Pilose Braya, <em>Braya pilosa</em> Hooker (Cruciferae; Brassicaceae), an Enigmatic Endemic of Arctic Canada
Bibliographic record
Abstract
Braya pilosa Hooker, Pilose Braya, has been poorly understood among North American botanists due to a paucity of fruiting specimens for study. This has resulted in confusion about the taxonomic position of the taxon within Braya, and has led to speculation about its generic status. An examination of fruiting specimens from the Royal Botanic Garden Herbarium at Kew, England reveals that B. pilosa is correctly placed in the genus Braya, and that it is a distinctive member of the genus deserving recognition at the specific level. I discuss the historical evidence that B. pilosa may not have been collected since 1850 due to its extremely restricted distribution on the Cape Bathurst Peninsula of the Northwest Territories of Canada. I also present evidence suggesting that B. pilosa is diploid and may be a parent species to some of the more widespread members of the genus, all of which are polyploid. Its closest living relative is probably B. thorild-wulffii.
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.
