31. Acalypha linearifolia Leandri Notulae Systematicae. Herbier du Muséum de Paris. Phanérogramie. Paris 10: 275 (Leandri 1942). — Type: Madagascar. Prov. Toliara, Ambovombe, Kotoala, 21.I.1931, R. Decary 8423 (lecto-, designated by Montero Muñoz et al. [2018a: 103]: P [P00513090]; isolecto-, S [S07-14664], TAN [TAN000510], US [US01014148]). — Former syntype: Madagascar. Prov. Toliara, delta de la Linta, 17-24.VIII.1928, H. Humbert & C. F. Swingle 5385 (P [P00513086, P00513087, P00513088, P00513089], US [US00096361]). ICONOGRAPHY. — Leandri (1942: 276); Fig. 57C. ETYMOLOGY. — The specific epithet refers to the linear leaf blades characteristic of this species. DISTRIBUTION AND HABITAT. — Endemic to Madagascar (Atsimo-Andrefana, Androy, and Atsinanana [one known collection]). Littoral forest and littoral thicket. On unconsolidated sand and Tertiary limestone. Altitudinal range sea level to 10 m (Fig. 50). PRELIMINARY CONSERVATION ASSESSMENT. — Acalypha linearifolia is known from five collections. Its EOO is estimated to be 84 834 km 2 and its AOO 16 km 2. The large EOO is due to one collection presumably made in Toamasina by G. Cours. The other collections are from southern Madagascar. This species grows mainly in littoral forests (see assessment of A. gracilipes). There are no collections made in protected areas. In addition, no specimens of this species have been collected for 70 years, so we cannot rule out that this species has become extinct. Due to habitat loss and the absence of recent collections, A. linearifolia is assigned a preliminary conservation status of Endangered: EN B2ab(ii,iii,iv); although it meets the values needed for a threatened category based on the B2 subcriterion, this species could probably be assessed as extinct (EX). MATERIAL EXAMINED. — 4 collections. Madagascar: Cours, G. 4637 (P[P00324458, P00513085]), 4638 (G, P[P00513084]); Decary, R. 8423 (P[P00513090], S[S07-14664], TAN[TAN000510], US[US01014148]); Humbert, H. 5385 (P[P00513086, P00513087, P00513088, P00513089], US[US00096361]).

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.
