Abstract
Recent molecular studies have redefined families and genera within the anthocerotes, but species boundaries are only now being revised. Monophyly of Australian and New Zealand taxa within the genus Megaceros Campb., which share the same spore and similar gametophyte morphology, was assessed. On the basis of sequence data, mainland Australian lineages are not monophyletic but are interspersed with New Zealand lineages. There are three species present in Australia, including the common and widespread M. gracilis (Reichardt) Steph., the widespread tropical M. flagellaris (Mitt.) Steph., recognised by its tesselated spores, and a new species, M. austronesophilus, found only in Tasmania and Macquarie Island. None of the currently recognised New Zealand taxa is conspecific with any of the Australian taxa. However, New Zealand lineages were found to be genetically and morphologically more diverse than is currently recognised.

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
