Abstract
Abstract Sequence data from the ribosomal internal transcribed spacer (ITS) region were used to determine the tribal placements of the previously unassigned genera Ivania, Scoliaxon , and Phravenia (gen. nov.; named in honor of Dr. Peter H. Raven). The utilization of the ITS‐based phylogenetic tribal backbone of Brassicaceae placed three genera in relation to the 44 recognized tribes in the family. Scoliaxon , although showing remarkable morphological similarities to Asta (Asteae), formed an independent clade with 100% bootstrap (BS) support in the tribal analysis, whereas both Ivania and Phravenia clustered with the Thelypodieae clade (96% BS support). In a second and more comprehensive analysis of Thelypodieae, both species of Ivania formed a clade with 61% BS support within the tribe and were affiliated to other Thelypodieae genera from the Southern Hemisphere. The monospecific Phravenia ( P. viereckii , formerly Arabis/Dryopetalon viereckii ) formed a clade with 74%–76% bootstrap support within Thelypodieae, and its species did not resolve with Dryopetalon or Sibara in which it had been previously assigned. The present findings support the placement of Ivania and Phravenia in Thelypodieae, as well as the recognition of the new genus Phravenia and new tribe Scoliaxoneae, both of which are formally described herein.

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
