A monographic account of Australian species of Amphiroa (Corallinaceae, Rhodophyta)
Bibliographic record
Abstract
The first Australia-wide monograph of Amphiroa (Corallinaceae, Rhodophyta) based on the morphological–anatomical species concept has confirmed the occurrence of nine species (A. anceps, A. beauvoisii, A. crassa, A. exilis, A. foliacea, A. fragilissima, A. gracilis, A. klochkovana, A. tribulus) and provides a basis for future molecular-systematics studies. A comparative analysis of 285 specimens from 121 localities, along with type material examinations, yielded clear evidence that nine characters associated with the vegetative system and tetrasporangial conceptacles were diagnostically significant at species level. Detailed accounts of each species are presented, along with an identification key, data on type specimens, species comparisons and biogeographic notes. A. foliacea is epitypified. Brief accounts of 34 additional taxa reported from Australia and at some stage ascribed to Amphiroa are included. Galaxaura versicolor and Amphiroa galaxauroides are heterotypic synonyms of A. anceps; recognition of A. anastomosans, A. ephedraea and A. nobilis as distinct species requires further evaluation; and A. dilatata and A. gaillonii are species of uncertain status. Amphiroa ephedraea is lectotypified. The remaining 27 names involve nomina nuda, illegitimate names, orthographic variants or taxa now excluded from Amphiroa.

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.
