Abstract
The checklist includes a listing of the genera and species of North American Bryophyta thought to occur in the continental United States and Canada. The floras of Mexico, Hawaii and Greenland are not included. The current list recognizes 1565 species, 12 subspecies, 34 varieties and one form (for a total of 1612 taxa) in 366 genera and 100 families. As a preface to the list, a systematic arrangement of the families and included genera for North America is presented. Many changes from the previous checklist are documented via footnotes that provide references to where changes were made. Only synonymy since the previous checklist is included. Twenty nomenclatural changes are made. These include 19 new combinations: Bryum brassicoides (≡ Gemmabryum brassicoides), B. pacificum (≡ Ptychostomum pacificum), B. torenii (≡ Imbribryum torenii), B. vinosum (≡ Gemmabryum vinosum), Chionoloma maragniphyllum (≡ Oxystegus maragniphyllus), Lescuraea tribulosa (≡ Pseudoleskea tribulosa), Pterygoneurum 3kieneri (≡ P. subsessile var. kieneri Habeeb), Pylaisiadelpha canadensis (≡ Brotherella canadensis), Streblotrichum convolutum var. eustegium (≡ Barbula eustegia), Streblotrichum convolutum var. gallinula (≡ Barbula convoluta var. gallinula), Voitia angustata (≡ Splachnum angustatum), V. mnioides (≡ Splachnum mnioides), V. pallida (≡ Tetraplodon pallidus), V. paradoxa (≡ Splachnum paradoxum), V. urceolata (≡ Splachnum urceolatum), Warnstorfia badia (≡ Hypnum badium), W. straminea (≡ Hypnum stramineum), W. straminea var. patens (Lindb.) (≡ Amblystegium stramineum var. patens), W. wickesiae (≡ Calliergon wickesiae). A new order is also introduced: Rhizogemmales W.R.Buck & Goffinet (≡ Rhizogemmaceae Bonfim Santos, Siebel & Fedosov).

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 it
