    Description: Trees up to 7 (12) m tall; young branches flattened, with interpetiolar ridges, densely covered by ferrugineous sessile-stellate and stipitate-stellate trichomes. Leaves discolorous; petioles 0.8-1.5 cm; blades 5-12.5 x 2.5-5 cm, elliptic to lanceolate, apex acuminate, base acute, margin enteire, not ciliate, membranaceous, longitudinal nerves 3, not joined at the base by a membrane, with an additional faint, marginal pair, basal or up to 1.8 mm above the base, main and transversal nerves covered by a ferruginous indument consisted of sessille-stelatte to lepidote trichomes, sometimes with additional stipitate-stellate to dendritic trichomes, abaxial surface with dense, canescent to ferruginous, indument consisting of sessile-stellate of long or short arms to lepidote trichomes, ca. 0.2 mm diam. Panicles 3-7 x 1.5-3 cm, sometimes with additional branches, branches secund, terminal, densely covered by a ferrugineous indument consisted of sessile-stellate, stipitate-stellate and, sometimes, glandulose-granulose trichomes; bracts and bracteoles lanceolate, up to 0.7 mm, caducous. Flowers 5-merous. Hypanthium 2-2.6 mm long, campanulate, inner surface sparsely to moderately covered by sessile-stelate trichomes, outer densely covered by sessile-stellate and stipitate-stellate trichomes, sometimes granulose-glandulose trichomes; torus glabrous. Calyx lobate, caducous in fruit, inner surface glabrous, outer with trichomes similar to the ones on the hypanthium; tube 0.2-0.4 mm long, inner lobes triangular, 0.1-0.3 mm long, outer teeth subulate. Petals 1.6-2 x 1.1-1.3 mm. Stamens white, slightly dimorphic; filaments 1.7-2.5 mm long, glabrous; connectives up to 0.3 mm prolonged below the thecae, with two small, ventral, appendages and a long dorsal tooth; anthers 1.2-1.4 mm long, oblong, with a single terminal, moderate pore, ca. 0.3 mm diam. Ovary 1.2-1.4 mm long, completely adherent to the hypanthium, 2-3-locular, apex densely covered by sessile-stellate; style 4.6-5 mm long, straight to slighly curved, punctiform, glabrous. Fruits purple, up to 3.7 x 4.2 mm, 2-7 seeds.

    Habitat and Distribution: Miconia cubatanensis occurs in the wet, coastal forests from Santa Catarina to Espírito Santo, and in the Campos Rupestres of the Espinhaço Moutains Range, in Minas Gerais and Bahia states, ranging from (50)600-1400m asl.
