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.

Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
