Amplified fragment length polymorphism analysis reveals three distinct taxa in<i>Carex digitalis</i>sect.<i>Careyanae</i>(Cyperaceae)
Bibliographic record
Abstract
Unweighted pair-group (UPGMA) cluster, neighbor-joining (NJ), and parsimony analyses using amplified fragment length polymorphism (AFLP) data revealed the presence of three taxa within Carex digitalis Willd. (var. digitalis , var. floridana , var. macropoda ). Even when taxa occur syntopically, genetic distinctiveness is maintained (Hertford Co., North Carolina populations of var. macropoda and var. floridana). Clades or clusters corresponding with vars. digitalis and floridana were well supported in all analyses. However, the var. macropoda clade was poorly supported on most trees. Despite our inability to fully resolve taxon relationships, AFLP data substantiate ongoing morphological and phytogeographic studies that show the presence of additional species diversity within sect. Careyanae and the eastern North American Carex flora.

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.
