Thirty-three taxa, comprising 32 species and a nothotaxon, are recognized for the Brazilian territory. We pr...

Eastern Minas Gerais has been historically neglected regarding biodiversity sampling effort. However, recent botanical explorations have revealed several new taxa for its flora, especially from disjunct fragments of campos rupestres vegetation, which form a mosaic with granitic inselbergs in the region. In this article, we add four new species of P...

Mikania is a pantropical genus of Asteraceae with ca. 450 species distributed mainly in South America. Although most of its species occur in forested phytophysiognomies, significant richness is found in the mountaintop grasslands known as campos rupestres in Brazil. Recent botanical exploration of campos rupestres areas outside their core distribut...

The complete life history of the kleptoparasitic ‘sundew flower fly’, Toxomerus basalis , is presented and illustrated. Adults of this species are photographed alive for the first time, including video recordings of larval and adult behaviour.

Recent collections of Lythraceae from an isolated mountain range in eastern Brazil were found to possess a unique morphology including spurless, weakly actinomorphic floral tubes, two deep red petals, a stipitate ovary and irregularly circumscissile dehiscence of a thickened capsule, characters typically applied to taxon recognition at the generic...

We present a taxonomic treatment of the species of Droseraceae in Espírito Santo state, Brazil. Droseraceae is represented in the state by two species: Drosera intermedia, found in marshlands in the restingas (pioneer formations), and Drosera latifolia, which occurs in the campos de altitude (ecological refuges) and on granitic inselbergs in areas...

The shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impedime...

Fieldwork focused on the Orchidaceae family from the Diamantina Plateau of the Espinhaço Range in Minas Gerais, Southeast Brazil, resulted in the rediscovery of Bulbophyllum barbatum almost 140 years after its original description, in 1882.

Here, we introduce the first new species of Paepalanthus subg. Xeractis to be described in the last three decades. Discovered in the SPA, it belongs to an emblematic lineage endemic...

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...

Hyptidendron Harley, one of the 19 genera recognized for the subtribe Hyptidinae, has some of its species with a narrow campos rupestres (a Brazilian vegetational formation) distribution, often restricted to a single mountain range. We report a new species, Hyptidendron pulcherrimum Antar & Harley, sp. nov., endemic to a single mountain in the Serr...

As deforestation and fire move forward over pristine vegetation in the Amazon, many species remain undiscovered and may be threatened with extinction before being described. Here, we describe two new species of Utricularia (Lentibulariaceae) collected during recent fieldwork in an area of white-sand vegetation in the eastern Amazon Basin named Camp...

Carnivorous plants (CPs)—those possessing specific strategies to attract, capture and kill animal prey and obtain nutrition through the absorption of their biomass—are harbingers of anthropogenic degradation and destruction of ecosystems. CPs exhibit highly specialised and often very sensitive ecologies, being generally restricted to nutrient-impov...
