Floral structures such as stamen appendages play crucial roles in pollinator attraction, pollinator positioning, pollen‐release dynamics and, ultimately, the reproductive success of plants. The pollen‐rewarding, bee‐buzz‐pollinated flowers of Melastomataceae often bear conspicuous staminal appendages. Surprisingly, their functional role in the poll...
Background
The Amazon Rainforest, a paramount source of global biological diversity, faces challenges due to its understudied species richness, an insufficient investment in research and escalating rates of deforestation. Thus, acquiring additional data, especially for species distributions is crucial to fill knowledge gaps and guide forthcoming re...

Background
The Parque Estadual do Forno Grande is a fully protected area in the southern Espírito Santo State, Brazil. It belongs to the Atlantic Forest domain, with predominantly dense, ombrophilous, seasonal semi-deciduous forests and herbaceous/shrubby vegetation on rock outcrops. The area is recognised as highly important for conservation, desi...
Background
The "Serra da Concórdia" is part of the Atlantic Forest phytogeographical domain in the Brazilian state of Rio de Janeiro and it has a predominant phytophysiognomy of Semideciduous Seasonal Forest. This region underwent intense habitat loss and fragmentation during the 19th century, due to coffee plantations and later pastures. With the...
Background
The Atlantic Forest is one of the most diverse and threatened phytogeographical domains in the world. Despite that, it includes regions with poor floristic knowledge, even in protected areas. Although the importance of protected areas in conserving the Atlantic Forest hotspot is undisputed, it is necessary to recognise the floristic rich...

The asymmetric pattern in species richness is a notable feature across different lineages and geographic regions. While some lineages have high richness, diversity and wide distribution, others have the opposite. Despite low rates of diversification, the latter might also be phylogenetically isolated. Lineages that accumulate these characteristics...
Campo rupestre and campo de altitude are two highly diverse plant formations that are found in montane areas in eastern Brazil. These formations are associated with landscapes having different geological histories and are part of different phytogeographic domains under different climatic conditions. It is unclear however, whether lineages in each a...

Bertolonieae s.l. has been characterized as herbaceous plants with angular capsules. Despite morphological similarities, molecular data showed that the lineages within it were not homologous, and the traditional diagnostic characters have several different origins in Melastomataceae. Recently, Bertolonieae s.l. was recircumscribed to include only B...
Pyramieae contains 68 species belonging to three genera: Cambessedesia, Huberia, and Merianthera. We review the systematics and evolution of Pyramieae, including the history of tribal placement of the genera, phylogenetic relationships, taxonomy with emphasis on morphological characters that define the tribe and its genera, and general ecology and...
Melastomataceae are the fifth richest plant family in the Atlantic Forest with 544 species belonging to few phylogenetic lineages and present considerable variation in habitat, ecological and reproductive characteristics, and morphology. Some of these lineages are prevailingly centered in the Atlantic Forest, being either endemic (Bertolonieae, Eri...
The shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiver-sity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxo-nomic impediment to biodiversity research and conservation planning. The taxonomic impedi...

The distribution of major clades in Bertolonia (Melastomataceae) is congruent with subareas of the Atlantic Forest, providing an opportunity to estimate ages of historical breaks in the Atlantic Forest, from its major north/south split to more restricted local radiations. The role of niche conservatism in driving diversification of Bertolonia is al...
We here describe two new species endemic to the state of Espírito Santo, Brazil, that belong to different clades within Miconia s.lat. Miconia quartzicola is presumably part of the Leandra s.str. clade, as indicated by its terminal inflorescences and petals with an acute apex. It has been collected only once in the municipality of Vargem Alta in di...
O Brasil abriga a maior diversidade florística mundial, com cerca de 32.696 espécies de angiospermas, sendo 55% endêmicas. Cambessedesia DC. é um gênero da família Melastomataceae exclusivamente brasileiro e altamente endêmico, compreende 24 espécies com 90% das espécies restritas ao Domínio do Cerrado, ocorrendo principalmente nas vegetações de ca...
The campo rupestre and the campo de altitude are two highly diverse vegetations types that characterize montane areas in eastern South America. These systems are associated with landscapes of different geological histories and are inserted within different phytogeographic domains and biomes. It is unclear, however, whether lineages with distributio...
Aim
There is little consensus on which environmental variables are best at predicting multiple dimensions of diversity. We ask whether there are common environmental correlates of diversity, despite ecological differences, across nine clades of plants and animals distributed along a single rainforest domain. For that, we compare the environmental c...
The urge to organise the world around us is an essential part of human nature. Naming and categorising enable us to store and access information ef ciently. The need to name and categorise extends to the natural world and, in particular, to living organisms. The science underpinning this area of knowledge is called Taxonomy, and is as old as humani...
Systematic studies based on DNA sequences have shown that some traditional tribal delimitations in Melastomataceae remain unresolved, such as the ‘Merianthera and allies’ clade, an informal group which has not been formally assigned to a tribe. This clade includes Behuria, Cambessedesia, Dolichoura, Huberia and Merianthera and occurs mainly at high...

The colonization of the epiphytic niche of tropical forest canopies played an important role in orchid’s extraordinary diversification in the Neotropics. However, reversals to the terrestrial habit occurred sparsely in species of Epidendroideae. To better understand which factors might have been involved in reversals to terrestrial habits in the pr...
We describe and illustrate Behuria lumiarensis, a new species from the state of Rio de Janeiro, Brazil. It has been collected only once in montane vegetation in the Municipality of Nova Friburgo. The new species can be recognized by the combination of leaf blades with adaxial surface covered with sessile glands and abaxial surface moderately covere...
This study was carried out in the state of Rio de Janeiro and led to the rediscovery of three endemic and threatened species of Behuria (Melastomataceae). The type specimens for these species were collected by the French botanist A.F.M. Glaziou. Behuria corymbosa and Behuria glazioviana were collected for the last time 127 years ago by him, in 1889...
