A reexamination of the taxonomic boundaries of <i>Symphysia</i> (Ericaceae)
Bibliographic record
Abstract
Abstract DNA sequence data were generated for the nuclear ITS region for Symphysia racemosa and for 26 additional Vaccinieae representing 12 sections in the genus Vaccinium plus one species from each of five additional segregate genera. Our focus is on the placement of S. racemosa relative to Vaccinium sensu stricto and Vaccinium sect. Oreades (represented by V. poasanum ). Maximum parsimony analysis of 608 bp of nrITS region suggests that S. racemosa and V. poasanum form a wellsupported clade in spite of substantial morphological divergence. Furthermore, this clade is a sister group to a clade consisting of all segregate genera examined. These molecular results led us to undertake a morphological cladistic analysis of all of the other Central American greenflowered taxa. We suggest that the genus Symphysia should be expanded to encompass these 15 taxa, despite the lack of phylogenetic resolution within this group. This will necessitate eight new combinations, viz., Symphysia almedae (= V. almedae ), Symphysia costaricensis (= V. costaricense ), Symphysia jefensis (= V. jefense ), Symphysia orosiensis (= V. orosiense ), Symphysia ovata (= Lateropora ovata ), Symphysia perardua (= V. santafeënsis ), Symphysia poasana (= Vaccinium poasanum ), Symphysia santafeënsis (= L. santafeënsis ), and Symphysia tubulifera (= L. tubulifera ).

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.
