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...

Material and methods – Our fieldwork in the inselbergs of the Atlantic Forest of the state of Espírito Santo led to...
Inselbergs are old outcrops, characterized by large expanses of open rocks and by distinct environmental filters. Many studies have been carried out on inselberg’s flora in the last decades. In contrast, vascular epiphytes received little attention compared to lithophytic groups. We aimed to investigate the role of inselbergs of the Espírito Santo...

The Flora of Espírito Santo presents three species of Helieae (Gentianaceae), circumscribed in the genera Prepusa, with two species, and Senaea with only one species. These poorly known species are described and illustrated here, and had their diagnostic characters and their similarities with other species discussed. In addition, this paper provide...
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 Atlantic Forest is one of the diversity centers of Melastomataceae in the world, and studies have been showing the great richness of its species in Espírito Santo, a state that once was entirely covered by this phytogeographic domain. We present here a floristic survey of the species of Melastomataceae in a protected area in this state, the Mun...
The Atlantic Forest is the most species rich vegetation in Brazil and holds several phytophysiognomies, including the vegetation on inselbergs, which is a very stressful xeric environment that selects for very specialized biota. Cololobus is an endemic genus from Atlantic Forest inselbergs of eastern Brazil, and Cololobus ruschianus is a new specie...

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...
Global patterns of species and evolutionary diversity in plants are primarily determined by a temperature gradient, but precipitation gradients may be more important within the tropics, where plant species richness is positively associated with the amount of rainfall. The impact of precipitation on the distribution of evolutionary diversity, howeve...
Background
Isolated monoliths of granitic and/or gneissic rock rising abruptly from the surrounding landscape are known as inselbergs. Dome-shaped inselbergs are common throughout the Atlantic Forest in south-eastern Brazil, a region known as Sugarloaf Land (SLL). This study aimed to create the first checklist of vascular plant species occurring on...
The papilionoid legume trees generally known as tonka , baru and cumaru comprise the taxonomically complex genus Dipteryx . In addition to being ecologically important across the neotropical biomes of rain forests and savannas, Dipteryx species are valuable sources of timber as well as an array of coumarin products. This genus currently comprises 1...
Joannesia is a genus of Euphorbiaceae composed of two endemics species to Brazil, one occurring in the Amazonia and another mainly on the Atlantic Forest. The genus was formally described by Frei José Mariano da Conceição Vellozo in 1798 but this taxon had been already mentioned by Willem Pies and Georg Marcgrave in 1648 under a different name. The...

The Global Strategy for Plant Conservation (GSPC) was established by the Conference of Parties in 2002 to decrease the loss of plant diversity, reduce poverty and contribute to sustainable development. To achieve this overarching goal, the GSPC has established a series of targets, one of which is to ensure that plant diversity is well understood, s...
Background – Davilla Vand. is a monophyletic genus and member, with other genera endemic to the Neotropics, of the Doliocarpoid clade, a natural lineage of the subfamily Doliocarpoideae J.W.Horn.
