29. Acalypha leptomyura Baill. Histoire physique, naturelle et politique de Madagascar Atlas, 2, Fasc. 27: t. 191 (Baillon 1891). — Type: Madagascar. Baillon 1891: pl. 191, holotype. ICONOGRAPHY. — Baillon (1891: t. 191); Figs 54C, D; 57A. ETYMOLOGY. — The epithet is taken from the Greek ‘leptos’, fine or delicate, ‘ myos ’, mouse, and ‘oura’, tail. It possibly refers to the thin rachis of the inflorescences. DISTRIBUTION AND HABITAT. — Endemic to Madagascar (Diana, Sofia, Betsiboka, Alaotra-Mangoro, Analamanga, Bongolava, Melaky, Menabe, Atsimo-Andrefana, Androy, Anosy, Atsimo-Atsinanana, and Ihorombe). Lowland evergreen moist forest, dry deciduous forest, and sclerophyllous woodland. On sandstone, unconsolidated sand, and Mesozoic limestone. Altitudinal range (15-) 100-1000 (-1400) m (Fig. 48). PRELIMINARY CONSERVATION ASSESSMENT. — The EOO of Acalypha leptomyura is estimated to be 385 705 km 2 and its AOO 120 km 2, which is less than the 500 km 2 threshold of the B2 subcriterion of the Endangered category. This species grows in a variety of forests: dry deciduous forests, (see assessment of A. diminuta), lowland evergreen moist forests (see assessment of A. emirnensis), and sclerophyllous woodlands, which mostly have been converted to secondary grasslands by human activities such as fires for agriculture or cattle grazing (Kull 2003; Gautier et al. 2018). This species has been collected in some protected areas, but it is also known from several unprotected forests subject to various threats. Ongoing habitat loss will cause continued decline of its EOO and AOO. Acalypha leptomyura 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 for a listing under the Endangered category.

Prédiction machine sur la base complète
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.
