fetched live from OpenAlex

KEY TO THE SECTIONS Of PLUKENETIA 1. Leaf venation pinnate,primary vein 1 (palmate, primary veins 3 in P. verrucosa); styles entirely connate into a cylindrical, depressed-subglobose,globose, obovoid, or oblong-obovoid column, 0.3–4.5 mm long; pollen tecta coarsely reticulate............ 2 (Pinnately veined clade, subclades P1 + P2) 2. Fruits 4–5 cm in diam, fleshy; pistillate flowers 1–10 per inflorescence; all anthers sessile and loosely packed on a globose receptacle, receptacles 2 mm or more in diam, visible between anthers; stipels 2, present adaxially at petiole apex; distributed in the Atlantic Forest region of Brazil ............................................................................................................ II. P. sect. Fragariopsis 2. Fruits 0.9–1.5 cm in diam, dry; pistillate flowers 1 per inflorescence; all or most anthers sessile and densely packed on a globose or subglobose receptacle, receptacles less than 1 mm in diam, not visible between anthers; stipels absent adaxially at petiole apex (2 in P. verrucosa); distributed in Mexico, Central America, northwestern and Amazonian South America, and the Lesser Antilles..................... V. P. sect. Penninerviae 1. Leaf venation palmate, primary veins 3(–5); styles partly connate into a cylindrical column, 1–35 mm long (entirely connate into a depressed-globose column 0.5–0.7 mm long in P. corniculata, or an obconic or obovoid column 3.5–5.5 mm long in P. ankaranensis); pollen tecta foveolate................................................................................................. 3 (Palmately veined clade, subclades P3–P5) 3. Styles 0.5–1.7 mm long, shorter than or nearly equal in length to the ovary; fruits dry capsules, 1.1–2 cm in diam; distributed in southern Africa or Southeast Asia......................................................................................... III. P. sect. Hedraiostylus 3. Styles 3.5–35 mm long, longer than the length of the ovary; fruits dry capsules or fleshy berries, 2.3–11 cm in diam; distributed in tropical central and western Africa, Madagascar, or the Neotropics................................................................................. 4 4. Staminate receptacles ellipsoid, oblong-cylindrical, or ovoid-conical; anthers sessile; nectaries absent; distributed in Madagascar ......................................................................................................... IV. P. sect. Madagascarienses 4. Staminate receptacles convex to subglobose; anthers on short-conical or slender-cylindrical filaments, 0.5–3 mm long; nectaries of interstaminal slender-cylindrical, ligulate, or small or large irregularly shaped segments (absent in P. volubilis); distributed in tropical central and western Africa or the Neotropics................................................................................................. 5 5. Stylar columns funnel-shaped, free style arms conspicuously dilated and spreading; stipels and glandular knobs absent adaxially at petiole apex; distributed in tropical central and western Africa................................................ I. P. sect. Angostylidium 5. Stylar columns cylindrical, free style arms more or less uniform in thickness or tapered and erect or spreading; stipels or glandular knobs present adaxially at petiole apex; distributed in the Neotropics........................................... VI. P. sect. Plukenetia

Not 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.
