“…For each previously recognized major clade up to six species were selected and their sequences downloaded from GenBank. We did not keep the traditional generic classification for Miconieae, based on Cogniaux (1891; see also Michelangeli et al, 2004;Michelangeli et al, 2008;Goldenberg et al, 2008;Reginato & Michelangeli, 2016); i.e., we showed all the names transferred to a single genus, Miconia s.l., as proposed in Michelangeli et al (2016;Michelangeli et al 2019). The old names are listed in Table S1.…”

“…1900 species native to the Neotropics . Its circumscription has been recently modified (see Michelangeli et al, 2016;Michelangeli et al, 2019), and now it is equivalent to the whole tribe Miconieae, in its modern definition (Michelangeli et al, 2004;Michelangeli et al, 2008;Goldenberg et al, 2008; see also Penneys et al, 2010;Michelangeli et al, 2011). This new circumscription includes former Miconia sensu stricto and several other genera, such as Leandra Raddi, Clidemia D.Don, Ossaea DC.…”

We describe Miconia lucenae R.Goldenb. & Michelang., a new species from the montane Atlantic Forest in Santa Teresa in the state of Espírito Santo. Our analysis, based on three plastid spacers (atpF -atpH, psbK -psbl and trnS-trnG), one plastid gene (ndhF, not available for M. lucenae), and two nuclear ribosomal loci (nrITS and nrETS), showed that it belongs to a small clade with Miconia paradoxa (Mart. ex DC.) Triana (Minas Gerais) and M. michelangeliana R.Goldenb. & L.Kollmann (Espírito Santo). The three species in the ''Paradoxa clade'' can be recognized by the plants with glabrous or glabrescent branches and leaves, white petals and yellow stamens, these with the connectives not prolonged below the thecae, ventrally unappendaged, dorsally unappendaged or with a minute tooth, the latter bilobed or not, glabrous ovary, and the fruits with a persistent calyx. Miconia lucenae can be recognized, among the species in this clade, by the shrubby plants with terete young branches, short inflorescences, usually with red axes, and the 2-bracteolate, sessile, 4-merous flowers, with a ciliolate inner portion of the sepals, lanceolate petals, and 4-celled ovaries. This species can be considered as endangered according to IUCN criteria.

“…Este conjunto de caracteres también se presenta en el género Tococa Aublet, que se diferencia de Miconia principalmente por la presencia de mirmecodomacios en ambas hojas y los pétalos emarginados apicalmente (Michelangeli, 2005). Sin embargo, y con base en filogenias moleculares, se reconoce que Miconia es un grupo parafilético, al igual que la mayoría de los géneros más diversos de la tribu (Michelangeli, et al, 2004Goldenberg, et al, 2008), razón por la cual se ha propuesto incluir a Tococa, así como a la mayoría de los géneros de Miconiaeae, dentro de Miconia (ver Michelangeli y Meier, 2013; Gamba y Almeda, 2014;Michelangeli, et al, 2016Michelangeli, et al, , 2018. doi: http://dx.doi.org/10.18257/raccefyn.848 Rev.…”

ResumenLa tribu Miconieae comprende cerca de 1.900 especies neotropicales y en recientes trabajos se propone solo un género para la tribu, Miconia, que incluye la totalidad de los géneros considerados previamente, entre los que se incluye el Tococa. En el presente trabajo se describe e ilustra una nueva especie bajo el género Miconia, que presenta anteras lateralmente connadas, procedente del departamento del Chocó, Colombia, la cual se asocia con las especies de la tribu Miconieae con anteras coherentes tales como Tococa symphyandra y Miconia croatii. Este nuevo taxón se identifica por el indumento de las ramas de tricomas elongados y alveolados, haz foliar bullada, el cáliz cerrado en botones y con grandes dientes dorsales, los pétalos y el estilo más grandes que las anteriores especies, y el ápice del ovario truncado. Crece en áreas muy húmedas de bosque subandino en la región central de la cordillera Occidental y hasta ahora solo se conoce de la localidad tipo. A new species of Miconia (Melastomataceae) with connate anthers from Colombia AbstractThe Miconieae tribe comprises about 1,900 Neotropical species and recent studies propose only one genus for the tribe, Miconia, which includes all of the genera previously considered including Tococa. Here we describe and illustrate a new species of the genus Miconia with lateral connate anthers from the department of Chocó, Colombia. This new taxon is associated with the species of the Miconieae tribe with laterally coherent anthers in a ring stamens such as Tococa symphyandra and Miconia croatii. This new taxon is characterized by the indument on branches with elongate and alveolate trichomes, bullate leaves, closed calyx in buds and with large dorsal teeth, bigger petals and style, and a truncated ovary apex. This new species grows in very humid areas of the sub-Andean forest in the central region of the Western Cordillera and at present, it is known only from the type locality.

We compiled a data set for all tree species collected to date in lowland Amazonian Ecuador in order to determine the number of tree species in the region. This data set has been extensively verified by taxonomists and is the most comprehensive attempt to evaluate the tree diversity in one of the richest species regions of the Amazon. We used four main sources of data: mounted specimens deposited in Ecuadorian herbaria only, specimen records of a large‐scale 1‐hectare‐plot network (60 plots in total), data from the Missouri Botanical Garden Tropicos® database (MO), and literature sources. The list of 2,296 tree species names we provide in this data set is based on 47,486 herbarium records deposited in the following herbaria: Alfredo Paredes Herbarium (QAP), Catholic University Herbarium (QCA), Herbario Nacional del Ecuador (QCNE), Missouri Botanical Garden (MO), and records from an extensive sampling of 29,768 individuals with diameter at breast height (dbh) ≥10 cm recorded in our plot network. We also provide data for the relative abundance of species, geographic coordinates of specimens deposited in major herbaria around the world, whether the species is native or endemic, current hypothesis of geographic distribution, representative collections, and IUCN threat category for every species recorded to date in Amazonian Ecuador. These data are described in Metadata S1 and can be used for macroecological, evolutionary, or taxonomic studies. There are no copyright restrictions; data are freely available for noncommercial scientific use (CC BY 3.0).
