Species delimitation remains a central problem in systematic, taxonomic and evolutionary studies. However, the precise delimitation of species depends on the criteria used to identify lineages and the specific species concept that is applied. Recently, multidisciplinary studies using different data sources have significantly improved the delimitati...
Subtribe Angraecinae (Orchidaceae: Vandeae) are mainly distributed in Africa, but with two genera, Campylocentrum and Dendrophylax, restricted to the Neotropics. As a widespread Neotropical genus, Campylocentrum constitutes an appropriate model for revealing biogeographical patterns in this area and investigating routes of colonization and dispersa...
Background:
Nectar gain and loss are important flower transitions observed in angiosperms, and are particularly common in orchids. To understand such transitions, the availability of detailed anatomical data and species-level phylogenies are crucial. We investigated the evolution of food deception in Epidendrum, one of the largest orchid genera, u...
In this study, we analyse a species complex in Epidendrum, a mega-diverse Neotropical orchid genus, that is formed by the 11 Brazilian species of the E. difforme group. Although this group (c. 100 taxa) exhibits relatively high levels of floral variation, the Brazilian species are similar, making delimitation problematic. Here we combine molecular...
To contribute to what is known about involvement of vegetation dynamics in Neotropical speciation, we used the Epidendrum latilabre complex, a taxonomically well-defined species group, to investigate past connections between Amazonian (AM) and Atlantic (AF) forests and address the following topics: (1) divergence times between sister species curren...
The state of Mato Grosso, in Central-West Brazil, is located within the Amazon Forest, Cerrado
and Pantanal phytogeographical domains, harboring diverse habitats for species of Epidendrum. The goal of
the present study was to develop a taxonomic treatment, including diagnoses, identification key, photographs
and distribution maps for the species of...
Because of polyphyly, the genus Maranta was expanded to include Hylaeanthe, Koernickanthe and Myrosma. Although most taxa in these genera already have combinations in Maranta, one species, Myrosma cannifolia, does not yet have a name available. We here propose the required combination (Maranta cannifolia) alongside an updated list of representative...
Baixada Cuiabana (Cuiabá lowlands) is a region in the south-central part of the state of Mato Grosso, comprehending the Pantanal and Cerrado phytogeographical domains. The flora of the region is scarcely known, but high levels of plant diversity are expected. Therefore, the goal of the present study is to contribute to the taxonomy of genus Bauhini...
