Labat, F. Barthelat, C.M. Hladik & A.B. Sifary 3268 (holo-, G [G00034240]; iso-, K, MAO, MO [MO-2965774], P [P00209719]). — Paratypes: Mayotte. Mamoudzou commune, îlot M’Bouzi, 12°48’57”S, 45°14’06”E, 90 m, 22.XI.2000, J.-N. Labat, F. Barthelat, C.M. Hladik & A.B. Sifary 3272 (G [G00034255], K, MAO, MO [MO-2966248], P [P00209724, P00209725]); îlot M’Bouzi, 12°48’39”S, 45°14’06”E, 26.XII.2002, F. Barthelat, A. de Vanssay & G. Rembert 1112 (MAO, P [P00339165]). — Precise location unknown, probably from M’Bouzi islet, 01.I.2010, G. Viscardi 310 (HKM, P [P02439826]). ICONOGRAPHY. — Montero Muñoz et al. (2020b); Figs 54F; 57E. ETYMOLOGY. — The epithet refers to Mayotte island, to which the small Mbouzi islet belongs, and to which this species appears to be endemic. DISTRIBUTION AND HABITAT. — Endemic to Comoros Archipelago (Mayotte). Dry forest and secondary forest. Altitudinal range 10- 90 m (Fig. 53). PRELIMINARY CONSERVATION ASSESSMENT. — Acalypha mayottensis is only known from Mbouzi islet. Its EOO and AOO are estimated to be 8 km 2. Mbouzi islet was declared a “Réserve Naturelle Nationale” in 2007, a category IV protected area (Dudley 2008). In the 1990s the islet had lost 70% of its original forests to agriculture. Mbouzi now conserves 10% of its natural and secondary forest. Currently, the most serious threat are invasive species, both animals, such as Eulemur fulvus, and plants, such as Antigonon leptopus, Lantana strigocamara, Leucaena leucocephala, Litsea glutinosa, Spathodea campanulata and Furcraea foetida (Boullet & Traclet 2018; Quintard et al. 2019). Due to its restricted geographic range and the threats from alien species, A. mayottensis is assigned a preliminary conservation status of Critically Endangered: CR B2ab(ii,iii).

Leaf blades 5-10 × 3-6 cm, ovate-lanceolate to elliptic-lanceolate, membranous; base rounded to subcordate; apex subacuminate to acuminate, acumen to 15 mm long, rounded; margin crenulate-serrulate to subentire, slightly revolute, teeth rounded; upper surface pubescent with simple, thin, erect trichomes, glabrescent; lower surface indumentum similar to that on upper surface but denser; axils of secondary veins with minute, sparsely hairy, pocket-shaped domatia, sometimes with hair-tuft domatia; margins ciliate in sinuses; venation actinodromous, basal veins 3, secondary veins 4-6 per side. Stipels absent. Inflorescences spiciform androgynous, axillary, to 6 cm long, mostly male with short female segment; peduncle thick, to 15 mm long, laxly pubescent with trichomes similar to those on young branches, glabrescent. Female segment to 2.5 cm long; bracts 1-2, sessile, enlarging in fruit to 19 × 21 mm, subreniform, veins and margin sparsely hairy with simple, erect trichomes to 1.5 mm long, glabrescent; margin crenate to subentire, sometimes dentate in young bracts, central tooth not prominent; bracteoles absent. Male segment persistent, to 4 cm long; flowers glomerate; bracts to 0.5 mm long, triangular, sparsely hairy. Male flowers: pedicel to 1 mm long, glabrous; buds to 0.7 mm diameter, sparsely hairy with simple, arachnoid trichomes. Female flowers 1 per bract, sessile; sepals 3[4], to 0.7 mm long, ovate-triangular, sparsely hairy with simple, arachnoid trichomes; ovary c. 1 mm diameter, 3-lobed, echinate, projections and surface hispid; styles 3, to 3 mm long, distinct, rachis thick, appressed-pubescent, each divided into 8-10 segments.

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.
