The genus Utricularia (Lentibulariaceae) is the most diverse and cosmopolitan among carnivorous plants. Utricularia sect. Foliosa sensu Taylor (1989) is composed of three South American species, U. amethystina, U. tricolor and U. tridentata, the first species being recognized as highly diverse. In his taxonomic revision of the genus Utricularia, Ta...
Article
Paepalanthus is the second largest genus of Eriocaulaceae, with about one-third of the species recorded for the family, but it has not received a recent comprehensive taxonomic treatment. Detailed taxonomic studies show that many names currently in use are actually synonyms. In addition, it was necessary to lectotypify some names. Twenty-five synon...

Leaf venation has not been widely used in taxonomic integrative works, although some potential in delimiting taxa has been reported. Hyptidendron, a neotropical genus with 20 species, seemed to present some variation in leaf venation patterns, which we sought to further investigate. A number of different herbaria were consulted, and herborized leav...

Short Abstract Here we present a reflection based on a long-term research in the Jalapão region (central-Brazil). If our initial interest was to understand local perceptions about the Brazilian Savanna's biodiversity, with time we have evolved our focus to a knowledge co-production perspective. The case studies were made through qualitative and com...
Article
A synopsis of the Drosera (Droseraceae) species occurring in Brazil is here presented, providing tools for taxonomic identification and summarizing data as a basis for future studies on diversity and conservation of the genus in the country. Thirty-three taxa, comprising 32 species and a nothotaxon, are recognized for the Brazilian territory. We pr...
Article
The fire regime is essential in creating a mosaic of plant structure and diversity in South American open savannas, especially favouring herbs. However, studies investigating diversity patterns in Neotropical savannas rarely focus on the herb–subshrub layer. This study investigated the variation of the herb–subshrub layer under contrasting fire reg...

Eugenia is one of the most taxonomically challenging lineages of flowering plants, in which morphological delimitation has changed over the last few years resulting from recent phylogenetic study based on molecular data. Efforts, until now, have been limited to Sanger sequencing of mostly plastid markers. These phylogenetic studies indicate 11 clad...

A recent phylogenetic tree for the large paraphyletic genus Paepalanthus showed that the genus Actinocephalus is also paraphyletic with two species of Paepalanthus nested within it: Paepalanthus macrocephalus and Paepalanthus camptophyllus. These species have the diagnostic morphological traits of Actinocephalus, but they are too small to be seen i...

A new species of Xyris endemic to Southern Brazil is described. Xyris serrana is placed in X. sect. Nematopus, which is characterized by having basal, suprabasal, or central placentation. The new species is known from few samples from the summits of Serra Geral, in Santa Catarina State. According IUCN criteria, the conservation status of the specie...
Article
Taxonomic monograph of Eugenia sect. Schizocalomyrtus, supported by molecular and morphological evidence, is presented. The flowers of this section have unusual fused calyces that are contrasted with standard Eugenia flowers with free calyx lobes. Because the fused calyx recurs in Myrtaceae and has been historically misleading for taxonomists, a ke...

We describe and illustrate Paepalanthus fabianeae, a new species of Eriocaulaceae from the central portion of the Espinhaço Range in Minas Gerais, Brazil. Previous phylogenetic evidence based on analyses of nuclear (ITS and ETS) and plastid (trnL-trnF and psba-trnH) sequences revealed P. fabianeae as belonging to a strongly supported and morphologi...
Article
Eugenia has ca. 1,100 species mostly with Neotropical distribution. Morphological circumscription of Eugenia has substantially changed over the last 10 years. Recent studies based on molecular and morphological data support a broad morphological circumscription of Eugenia including species with calyx fused and displaying apparently six petals. This...

Myrtaceae includes the genus Eugenia with ca. 1100 species mostly distributed in South and Central America. Molecular phylogenies currently support a broad and monophyletic Eugenia including species with bud closed by the fused calyx but splitting at anthesis, style length twice as the stamens, and ovary internally hairy. These characters have been...

Lepechinia is a New World genus of Lamiaceae with ca. 45 species. There is ongoing controversy regarding the recognition and delimitation of Lepechinia that occur in Brazil. After fieldwork and herbaria consultation we recognize two species of Lepechinia in Brazil: Lepechinia speciosa, distributed within the Mantiqueira region, and Lepechinia annae...
Article
Uncovering phylogenetic diversity is important, but not simple. A species complex is defined by different taxa with close evolutionary relationships harbouring limited morphological and/or genetic gaps. One such example exists within neotropical Utricularia sect. Foliosa, which is a taxonomically problematic assemblage composed of three currently r...

Many recent studies discuss the influence of climatic and geological events in the evolution of Neotropical biota by correlating these events with dated phylogenetic hypotheses. Myrtaceae is one of the most diverse Neotropical groups and it therefore a good proxy of plant diversity in the region. However, biogeographic studies on Neotropical Myrtac...
