7. Acalypha boinensis Leandri Notulae Systematicae. Herbier du Muséum de Paris. Phanérogramie. Paris 10: 268 (Leandri 1942). — Type: Madagascar. Prov. Mahajanga, Ambongo et Boïna, bassin moyen du Bemarivo, 200 m, XI.1919, H. Perrier de la Bâthie 9823 (lecto-, designated by Montero Muñoz et al. (2018a: 93): P [P00508582]). — Former syntypes: Madagascar. Prov. Mahajanga, Maintirano, s.d., R. Decary 8216 (P [P00508588]); Maromandia (Andranosamontana), s.d., R. Decary 1045 (P[P00508585]); Morovoay, s.d., H. Humbert & H. Perrier de la Bâthie 2350 (P [P00508570, P00508571, P00508572, P00508573, P00508574]); Ambongo et Boïna, 300 m, s.d., H. Perrier de la Bâthie 9546 (P [P00508576]), 9551 (P[P00508577]); Prov. Toliara, Forêt de Besomaty, entre le Fiherena et l’Isahaina (Mangoky), 750-800 m, s.d., H. Humbert 11234 (P [P00508575]). — s.l., s.d., Baron 5393 (P[P00508586]), 5450 (P [P00508587]). ICONOGRAPHY. — Leandri (1942: 257); Figs 24D; 28D, E. ETYMOLOGY. — The epithet refers to the former Iboina or Boina Region (now Mahajanga province) in northwestern Madagascar. DISTRIBUTION AND HABITAT. — Endemic to Madagascar (Sava, Sofia, Boeny, Betsiboka, Melaky, Menabe, Atsimo-Andrefana, Haute Matsiatra, Ihorombe, and Androy). Dry deciduous forest, dry spiny thickets, and medium altitude moist evergreen forest (Analavelona). On Mesozoic limestone, basalt, and sandstone. Altitudinal range (50-)200-1000(-1250) m (Fig. 20). PRELIMINARY CONSERVATION ASSESSMENT. — The EOO of Acalypha boinensis is estimated to be 388 446 km 2 and its AOO 140 km 2, which is less than the 500 km 2 threshold of the B2 subcriterion of the Endangered category. This species grows mainly in western dry deciduous forests (see A. diminuta assessment). It has been collected in some protected areas, but it is also known from several unprotected forests subject to various threats (uncontrolled fires for grazing and crops, logging, mining, etc.). Ongoing habitat loss will cause continued decline of its EOO and AOO. Acalypha boinensis is assessed as Near Threatened (NT) under criterion B. It meets the AOO values needed for a threatened category, but the number of locations is too high to meet the conditions required to list it under the Endangered category. MATERIAL EXAMINED. — 45 collections. Madagascar.

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.
