Abstract
Abstract— Cuscuta nuwuviana , a new species from southwest Utah and northwest Arizona is described and illustrated. The phylogenetic analyses revealed that the new species belongs to a subclade of C. sect. Californicae (subg. Grammica ) that also includes C. draconella and C. decipiens . Although not statistically significant, a topological incongruence between the plastid and nuclear data suggests that C. draconella resulted from the homoploid hybridization of C. nuwuviana and C. decipiens , accompanied by plastid introgression. Optical and scanning electron microscopy were employed to morphologically distinguish C. nuwuviana from C. draconella and C. decipiens , and an identification key was provided. Field investigations allowed the description of the habitat and plant community of the new species, which is currently known from only two populations in which it parasitizes solely Gutierrezia microcephala (Asteraceae). Evolutionary relationships, infrastaminal scales, and the presence of floral stomatiferous protuberances in C. sect. Californicae are discussed.

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
