ETYMOLOGY. — The epithet refers to the position of the female bracts near the middle of the bisexual inflorescences (Radcliffe-Smith & Govaerts 1997). DISTRIBUTION AND HABITAT. — Endemic to Madagascar (Menabe, Atsimo-Andrefana, Androy, and Anosy). Dry deciduous forest, dry spiny thickets, and sometimes in riparian forest. On basement rocks, Tertiary limestone, sandstone, and unconsolidated sand. Altitudinal range 100-800 m (Fig. 55). PRELIMINARY CONSERVATION ASSESSMENT. — The EOO of Acalypha medibracteata is estimated to be 85 039 km2 and its AOO 92 km 2, which is less than the 500 km 2 threshold of the B2 subcriterion of the Endangered category. This species grows mainly in dry deciduous forests and spiny thickets (see assessment of A. decaryana). The remaining original vegetation is still decreasing (Moat & Smith 2007, Gautier et al. 2018). A. medibracteata 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.). We predict that ongoing habitat loss will cause continued decline of its EOO and AOO. Acalypha medibracteata is assessed as Near Threatened (NT) because its AOO meets the threshold needed for a threatened category, but the number of locations is too high to meet the conditions required for a listing under the Endangered category.

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.
