5.5. Miconia cinnamomifolia ( Candolle 1828: 194) Naudin (1850: 168)   . [ Figs. 3j–k View FIGURE 3 , 7f–k View FIGURE 7 ]

Trees, sometimes treelets, 4–15 m; indumentum sparsely furfuraceous-stellulate, the trichomes early-caducous. Branches nodes with interpetiolar pseudo-stipules as lamellar protrusions, flat or revolute, latelly caducous. Petioles 7–24 mm long; blade 6.9–13 × 3.3–7.2 cm, discolour green, adaxial surface bright, generally blackness in colour when dried, chartaceous, elliptic to obovate, base acute or acute-cuneate, apex acuminate, margin entire; abaxial surface glabrescent with epidermic surface completely exposed; acrodromous veins 3, 2– 7 mm suprabasal, rarely basal. Thyrsoids 4.2–12.9 cm long; bracts 1.7–1.9 × 0.5–0.6 mm, bracteoles 0.3–0.5 × 0.05–0.1 mm, both navicular, early-caducous. Flowers 5-merous, pedicelate; hypanthium ca. 1.5 × 1.3 mm, campanulate, slightly costate to the apex; inner torus glabrous; calyx caducous, lobes 0.5–0.6 × 0.9–1 mm, broadly ovate; petals 3–3.3 × 1.1–1.8 mm, white, oblong-obovate, apex rounded to asymmetric-truncate; stamens subequal in size; anthers straight, connective 0.1–0.2 mm prolonged, antesepalous with filaments 3–3.1 mm long, anthers 2–2.4 mm long, appendage unilobed or bilobed, antepetalous with filaments 2.8–2.9 mm long, anthers 2–2.2 mm long, appendage dorsally with a minute calcar and latero-ventrally 2-auriculate; ovary 1–1.1 × 1–1.2 mm, inferior, 3-celled, glabrous; style 7–7.2 mm long, enlarged at the apex, glabrous. Baccaceous 2.6–4 × 2.5–5 mm, purple-blackness, globose, polyspermous (ca. 30 seeds); seeds 1–1.3 × 0.8–1.1 mm, obovate to ovate, testa granulose.

Distribution:—Endemic to the Atlantic Forest Biome of Brazil where it occurs from the state of Bahia to Santa Catarina (Goldenberg 2012).

Comments:—In Marambaia, this species is found in Shrubby Restinga, Restinga Forest, and Dense Submontane Ombrophilous Forest. Miconia cinnamomifolia   can also be distinguished by the discoloured green leaves, with a bright adaxial surface that is generally nigrescent when dried, and the caducous calyx.
