Abstract
Mezoneuron ouenensis (Guillaumin) R. Clark comb. nov. Basionym. Caesalpinia ouenensis Guillaumin, Bulletin de la Société Botanique de France 83: 308–309. 1936. Holotype:— NEW CALEDONIA: Balansa, B. 312, 27 ‘7bre’ 1868 (fl.) P (P00379653!) Shrub, 1– 2 m. Stems without recurved prickles, glabrous. Stipules unknown. Leaves bipinnate, unarmed, all parts glabrous; pinnae 2–3 opposite pairs, paripinnate; leaflets opposite, 1–2 pairs per pinna; petioles 2.5–3.5 cm; rhachis 6.5–7.5 cm; pinnae 1.5–3.8 cm. Leaflets orbicular to obovate, base oblique, apex rounded; 3.3–5 × 2.7–4 cm; secondary veins anastomosing, visible on both surfaces. Inflorescence an axillary raceme, c. 7 cm long, all parts glabrous. Pedicels 8–10 mm, not articulated. Bract at base of pedicel 2–3 mm long, lanceolate. Hypanthium c. 3mm deep, glabrous, lower calyx lobe c. 9 × 3 mm, other lobes c. 6–7 × 3 mm, glabrous. Median petal size unknown, lateral petals c. 11–13 mm long. Stamens 10, c. 12–15 mm long, glabrous; ovary not seen. Fruit unknown. (Figure 2) Distribution:— Endemic to New Caledonia. Known only from the type specimen, collected on Ile Ouen (South Province). (Figure 7) Habitat and Ecology:— The edge of a stream. Vegetation not stated on specimen label, inferred to be maquis on ultramaphic substrate, as this is the only native vegetation type on Ile Ouen. Phenology:— Unknown. Preliminary Conservation Assessment:— Category assigned:— Critically Endangered Rationale:— M. ouenensis is determined here as Critically Endangered, as it is known only from a single specimen, collected in 1868. Ile Ouen, the type locality, is a small island (c. 8.7 × 7.2 km), which is inhabited and has been subject to anthropogenic disturbance that may have destroyed the population from which the type specimen was derived. There are very few herbarium collections from this island, particularly from recent years. This could indicate either that there is little of interest to collect on the island, which could be a result of destruction of the vegetation, or simply that the island is seldom visited by collectors. A survey of the island is required to verify this assessment.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
