“…This plastid data set is still the most employed source of information in studies focusing on generic relationships across the family (Fritsch et al, 2004; Renner, 2004; Amorim, Goldenberg & Michelangeli, 2009; Michelangeli et al, 2011; Goldenberg et al, 2012; Michelangeli, Ulloa & Sosa, 2014; Goldenberg et al, 2015; Zeng et al, 2016). Phylogenetic studies within lower lineages of Melastomataceae have predominantly used the plastid spacers accD-psaI , atpF-atpH , psbK-psbI , and trnS-trnG , along with the ribosomal spacers nrETS and nrITS (Bécquer-Granados et al, 2008; Reginato, Michelangeli & Goldenberg, 2010; Kriebel, Michelangeli & Kelly, 2015; Reginato & Michelangeli, 2016). Recently, the latter data set has also been used at deeper level studies (Michelangeli et al, 2013; Rocha et al, 2016).…”

“…Early studies have consolidated the sister relationship of Olisbeoideae and the remaining Melastomataceae, settling on the currently accepted family circumscription (Conti, Litt & Sytsma, 1996; Angiosperm Phylogeny Group, 1998; but see Clausing & Renner, 2001 for a different perspective). Latter studies focused in some tribal re-arrangements (Fritsch et al, 2004; Penneys et al, 2010; Michelangeli et al, 2011), generic placement (Amorim, Goldenberg & Michelangeli, 2009; Goldenberg et al, 2012; Michelangeli, Ulloa & Sosa, 2014; Goldenberg et al, 2015; Kriebel, 2016; Rocha et al, 2016; Zeng et al, 2016), phylogenetic evaluation of higher species-rich lineages (Michelangeli et al, 2004; Stone, 2006; Goldenberg et al, 2008; Martin et al, 2008; Michelangeli et al, 2008; Michelangeli et al, 2013), and lower taxon phylogenies (Bécquer-Granados et al, 2008; Reginato, Michelangeli & Goldenberg, 2010; Penneys, 2013; Kriebel, Michelangeli & Kelly, 2015; Gamba-Moreno & Almeda, 2014; Majure et al, 2015; Reginato & Michelangeli, 2016). Even in family-wide phylogenies, the level of variation across these few sampled plastid markers is unsatisfactory, as evidenced by low statistical support among many relationships in different published analyses.…”

“…Even in family-wide phylogenies, the level of variation across these few sampled plastid markers is unsatisfactory, as evidenced by low statistical support among many relationships in different published analyses. This issue becomes more prominent in phylogenetic analyses of lineages within Melastomataceae, where the plastid phylogeny is overall weakly supported, and concatenated results tend to be dominated by the more variable nuclear ribosomal data (Reginato, Michelangeli & Goldenberg, 2010; Reginato & Michelangeli, 2016). …”

BackgroundIn the past three decades, several studies have predominantly relied on a small sample of the plastome to infer deep phylogenetic relationships in the species-rich Melastomataceae. Here, we report the first full plastid sequences of this family, compare general features of the sampled plastomes to other sequenced Myrtales, and survey the plastomes for highly informative regions for phylogenetics.MethodsGenome skimming was performed for 16 species spread across the Melastomataceae. Plastomes were assembled, annotated and compared to eight sequenced plastids in the Myrtales. Phylogenetic inference was performed using Maximum Likelihood on six different data sets, where putative biases were taken into account. Summary statistics were generated for all introns and intergenic spacers with suitable size for polymerase chain reaction (PCR) amplification and used to rank the markers by phylogenetic information.ResultsThe majority of the plastomes sampled are conserved in gene content and order, as well as in sequence length and GC content within plastid regions and sequence classes. Departures include the putative presence of rps16 and rpl2 pseudogenes in some plastomes. Phylogenetic analyses of the majority of the schemes analyzed resulted in the same topology with high values of bootstrap support. Although there is still uncertainty in some relationships, in the highest supported topologies only two nodes received bootstrap values lower than 95%.DiscussionMelastomataceae plastomes are no exception for the general patterns observed in the genomic structure of land plant chloroplasts, being highly conserved and structurally similar to most other Myrtales. Despite the fact that the full plastome phylogeny shares most of the clades with the previously widely used and reduced data set, some changes are still observed and bootstrap support is higher. The plastome data set presented here is a step towards phylogenomic analyses in the Melastomataceae and will be a useful resource for future studies.

Resumo Melastomataceae é a sexta família de angiospermas com maior número de espécies no Brasil e a sétima no Espírito Santo, apesar deste ainda apresentar poucos trabalhos relacionados a esta família. O objetivo do presente estudo foi realizar o levantamento florístico-taxonômico de Melastomataceae na Área de Proteção Ambiental Mestre Álvaro (APAMA), localizada no município da Serra, Região Metropolitana de Vitória, um remanescente de Floresta Atlântica que apresenta importantes fragmentos florestais em estágios avançados de regeneração. Expedições de campo foram realizadas entre 2012 e 2014. Também foram analisados espécimes depositados nos herbários VIES, MBML e SP. Na APAMA foram encontradas 26 espécies distribuídas em 10 gêneros, um acréscimo de 22 espécies em relação ao Plano de Manejo da APAMA, o único inventário da flora existente para a área. Behuria mestrealvarensis, endêmica da APAMA, Bertolonia ruschiana e Leandra triantha, endêmicas do Espírito Santo, são consideradas ameaçadas de extinção. A maior riqueza de espécies foi encontrada na Floresta Ombrófila Densa Montana, com 22 espécies, das quais 18 são exclusivas deste tipo de vegetação. São apresentados chave ilustrada de identificação, descrições, comentários sobre a distribuição geográfica e estado de conservação das espécies.

“…Phylogenetic analyses have shown that with few exceptions (e.g., Mecranium Hook.f. ; see Skean 1993), all of these genera are polyphyletic (Bécquer-Granados et al 2008, Goldenberg et al 2008, Martin et al 2008, Michelangeli et al 2004, 2008; Kriebel et al 2015, Majure et al 2015, Reginato and Michelangeli 2016) and undiagnosable, if recognized in the broad sense as currently circumscribed (e.g., Leandra Raddi s.l. ; Majure et al 2013).…”

Miconia sect. Lima is an entirely Greater Antillean clade that consists of 19 known species of shrubs and small trees, which were previously recognized under the polyphyletic genera Leandra and Ossaea. The highest species richness in the clade is represented on Cuba (10 species), followed by Hispaniola (8 species) and then Jamaica (1 species). Here we present a taxonomic revision of the clade based on the study of species in the field, herbarium specimens, as well as a DNA-based phylogeny reconstruction. The Lima clade most likely originated on Cuba and then spread to Jamaica once and Hispaniola multiple times. Species of this clade can be recognized by the well developed bulla-based hairs of the adaxial leaf surface, as well as the clavate-dendritic hairs produced along the primary, secondary and tertiary veins of the adaxial leaf surface, mostly towards the leaf base, terminal inflorescences, acute petal apices, slightly bulla-based hairs produced subapically along the petal abaxial surface, and anthers with a dorso-basal appendage and a single, dorsally oriented pore. Descriptions, synonymies, along with distribution maps and illustrations/figures, are given for each species. Miconia pagnolensis sp. nov. is newly described in this revision.
