A new species of Miconia sect. Miconia subsection Seriatiflorae. was collected in Igapó Forest from the Purus-Madeira interfluve, in the state of Amazonas, Brazil. This new species, Miconia suberosa, can be distinguished from other species in the subsection by a variety of morphological features, namely: (i) treelet habit; (ii) deeply fissured bark with a thick cork; (iii) long dendritic hairs with short arms on young branches, inflorescences and leaves; (iv) petiolated leaves with rounded to obtuse bases, and ciliate margins, congested at the branch apices; and, (v) truncated stigmas. © 2014 Magnolia Press.1734278284Bentham, G., Report on the plants collected by Mr. Spruce at Pará (1850) Hooker's Journal of Botany and Kew Garden Miscellany, 2, p. 241Black, G.A., Dobzhansky, T.H., Pavan, C., Some attempts to estimate species diversity and population density of trees in Amazonian forests (1950) Botanical Gazette 111 (4), 413, pp. 413-425. , http://dx.doi.org/10.1086/335612Bührnheim, C.M., Carvalho, T.P., Malabarba, L.R., Weitzman, S.H., A new genus and species of characid fish from Amazon basin - the recognition of a relictual lineage of characid fishes (Ostariophysi: Cheirodontinae: Cheirodontini) (2008) Neotropical Ichthyology, 6, pp. 663-678. , http://dx.doi.org/10.1590/s1679-62252008000400016Cogniaux, C.A., Melastomaceae (1886) Flora Brasiliensis, 14 (4), p. 655. , In: Martius, C.F.P. & Eichler, A.w.
