5.9. Miconia prasina ( Swartz 1788: 69) Candolle (1828: 188)   . [ Figs. 3n View FIGURE 3 , 8n–q View FIGURE 8 ]

Treelets or trees, 2–7 m; indumentum of the branches, leaves, inflorescences, hypanthium and calyx furfuraceousstellulate, the trichomes caducous. Petioles 0.5–1.3 cm long; blade 10.9–26 × 4–8.7 cm, green, concolour to subconcolour, membranaceous to papiraceous, elliptic, base acute-decurrent or obtuse-cuneate, apex acuminate to acute, margin crenulate, abaxial surface early-glabrescent; acrodromous veins 5, the inner pair 15–44 mm suprabasal. Thyrsoids 9.9–19.9 cm long, no branchlets of glomerules; bracts ca. 1 × 0.5–0.8 mm, bracteoles 0.7–0.9 × 0.2–0.4 mm, both concave, oblong-triangular, apex acute, persistent. Flowers 5-merous, pedicelate; hypanthium 1.5–2.1 × 1.2–1.9 mm, campanulate; inner torus glabrous; calyx persistent, lobes 0.6–0.9 × 0.8–1 mm, triangular; petals 2–2.5 × 1–1.6 mm, white, asymmetric, ovate, apex obtuse to rounded, sometimes emarginate; stamens isomorphic, subequal in size; filaments 3–4 mm long; anthers 2.8–3 mm long, white, pore terminal, connective slightly prolonged, appendage bilobed, with lateral and ventral lobes, or 3-lobed, with an additional dorsal calcar; ovary 0.8–1.3 × 1–1.5 mm, inferior, 3-celled, puberulous; style 5.8–6.5 mm, glabrous. Bacidium 3–4 × 3.2–4.2 mm, subglobose, puberulous, polyspermous (50–80 seeds); seeds 0.7–1 × 0.4–0.9 mm, narrowly obtriangular.

Distribution:—This species has a wide distribution, occurring from southern Mexico, Central America and the West Indies to Paraguay. In Brazil, it is found in almost all states, usually in open areas (Goldenberg 2009, 2012).

Comments:—In Marambaia, M. prasina   occurs in Restinga Forest and Dense Submontane Ombrophilous Forest, and it is a great source of food for the local fauna. This species can also be identified by the adult green concolored to subconcolored leaves, the distinctly suprabasal acrodromous venation, and the bilobed connective with latero-ventral lobes, or 3-lobate, due to the presence of a dorsal appendage.
