A new phylogeny and phylogenetic classification for Solanaceae
Bibliographic record
Abstract
Abstract Solanaceae are a globally distributed family of considerable economic importance. Recent phylogenetic work on various clades in the family has resulted in a plethora of names at various taxonomic levels. This results in a confusing set of names applied to clades at different ranks, and to the use of informal names that are often not accepted in online resources. To solve this problem, we present here a phylogenetic classification following the PhyloCode for the Solanaceae. Traditional taxon names previously recognized at the ranks of tribe, genus, and section were maintained when associated with clades. We base our clade definitions on a newly constructed phylogeny of the family using 10 plastid and nuclear markers with a broad sampling of 1474 species, roughly half of the diversity of the family. We complement this marker‐based analysis with a phylogenomic analysis of 110 taxa (including 97 of the 103 genera in the family and the outgroup Ipomoea purpurea ) using the Angiosperms353 probe set. This pair of analyses produced highly concordant phylogenies and provided strong support for the clades included in the classification. In total, we propose and define rank‐free names for 38 major clades, including 16 infrageneric taxa within the mega‐diverse Solanum . This rank‐free system intends to promote name stability as new data become available, avoiding name changes to well‐known groups.

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.
