A re-examination of the genus <i>Leptofauchea</i> (Faucheaceae, Rhodymeniales) with clarification of species in Australia and the northwest Pacific
Bibliographic record
Abstract
Abstract:Recently collected material from Coffs Harbour, New South Wales, Australia, was identified as the generitype of Leptofauchea, L. nitophylloides. This facilitated a re-examination of Leptofauchea and its constituent species to assess monophyly. Multigene phylogenetic analysis of COI-5P, LSU and rbcL solidly allied species assigned to Leptofauchea in previous studies with the generitype, establishing for the first time monophyly for this genus. In addition to L. nitophylloides, COI-5P barcode analyses revealed a second Australian species of Leptofauchea from the Cocos (Keeling) Islands, Indian Ocean, described as L. cocosana sp. nov. Further, COI-5P barcode analyses resolved collections assignable to Leptofauchea from South Korea as two genetic species groups. One of these groups was L. leptophylla; whereas, the second genetic species group warranted description of L. munseomica sp. nov. GenBank entries for the two species of Leptofauchea previously reported in the northwest Pacific (L. leptophylla described from Japan and L. rhodymenioides described from the Caribbean) were resolved as conspecific (a cryptic complex at best) and morphologically assigned to L. leptophylla.Key Words:: COI-5PLeptofaucheaL. cocosana sp. novL. munseomica sp. novL. nitophylloidesLSUrbcLSystematics ACKNOWLEDGEMENTSWithout the collection assistance of H-G.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
