Infrageneric Phylogeny and Systematic Position of the Acoraceae Inferred from ITS,18S and rbcL Sequences
Bibliographic record
Abstract
Inferred from the recent molecular data, Acorus was upgraded as a monotypic family, Acoraceae, although it was placed in the Araceae for a long time. The internal transcribed spacer (ITS) regions of A.gramineus,A.tatarinowii,A.calamus (with four populations sampled, representing tetraploids and hexaploids,respectively) and A.tatarinowii var. flavomarginatus were sequenced to examine the infrageneric relationship of the genus. The Acoraceae is supported as a monophyletic group.The tetraploid and hexaploid populations of A.calamus from different areas of Yunnan constituted a firm clade with high bootstrap support (100%), while A.gramineus,A.tatarinowii and A.tatarinowii var. flavomarginatus constituted another monophyletic clade with a bootstrap value of 100%.The systematic position of Acoraceae is analyzed by using the sequence data of nuclear 18S and chloroplast rbcL genes. Inferred from both phylogenetic trees of the 18S and rbcL genes, Acoraceae is in an insular position in the monocotyledons.

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.
