Abstract
20. PLUKENETIA ˟ HUAYLLABAMBANA Bussmann, C.Téllez & A.Glenn, Nordic J. Bot. 27 (4): 313. 2009. TYPE: PERU. Región Amazonas: Provincia de Rodr´ıguez de Mendoza, El Cedro-Cruzpata, [-6.404°, -77.449°], 1676 m, 5 July 2008, C. Téllez, C. Vega & L. Cabrera 02 (holotype: INBIAPERU [Instituto para el Desarrollo Local Sostenible y la Conservación Biológica y Cultural Andino-Amazónica, Trujillo]; isotype: K [barcode K001089689; image!]). [The isotype was originally published as housed at MO (Bussmann et al. 2009), but only one sheet of a different collection (Téllez et al. 004, MO! [accession 6116702, barcode MO-2255093]) incorrectly labeled as an isotype could be found. The isotype has since resurfaced at Kew (Téllez et al. 02, K [barcode K001089689; image!]) and it appears to be the isotype that was originally deposited at MO (“Ex Herbarium” MO [accession 6116701]).] Discussion — Plukenetia ˟ huayllabambana, along with P. carolis-vegae and P. sylvestris, form a high elevation species complex sister to P. volubilis. Members of the species complex grow in high elevation montane rainforest in the Andes, 1280–2440 m, and possess staminate flowers with large irregularly shaped interstaminal nectary segments, short styles partly connate into a cylindrical column usually <10 mm long, and 1–2 thick stipels at their petiole apex. Members of the species complex also have larger fruits and seeds, fruits 4–10 cm in diam with “extra-large” seeds in P. ˟ huayllabambana and P. carolis-vegae, and fruits 2.8–3.7 cm in diam with “large” seeds in P. sylvestris (similar in size to P. volubilis but with larger seed volume; Cardinal-McTeague et al. 2019a). This species is a putative hybrid between P. sylvestris ˟ P. volubilis, which is supported by the presence of a P. volubilis plastid genome in accessions of P. ˟ huayllabambana (Cardinal-McTeague et al. 2019a, Fig. S3) and their intermediate staminate floral morphology. Both P. ˟ huayllabambana and P. volubilis have stamens with short filaments,; 0.5 mm long, compared to longer filaments,; 0.5–1.4 mm long, in P. sylvestris. Staminate sepal number also appears to differ, more frequently with 5 (rarely 4) sepals in P. ˟ huayllabambana and, regularly varying from 4–5 sepals in P. sylvestris, and with 4 sepals in P. volubilis. Plukenetia ˟ huayllabambana is distributed in the Amazonas and Cajamarca Regions of northern Peru (Fig. 6). It is known from only a few collections across three districts but is possibly more common in cultivation. Its staminate flowers were originally described as having filaments 0.1–0.3 mm long and [nectary] disc absent (Bussmann et al. 2009), but our observations found filaments; 0.5 mm long and large irregularly shaped interstaminal nectary segments to be present (Quipuscoa 381 MO). The original type illustration shows an immature staminate flower dissected from a bud, whereas the staminate flower at anthesis is aberrant and likely from a non-euphorb species (Bussmann et al. 2009, Figs. 1J and 1H, respectively).

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.
