Guapira leucophylla (Nyctaginaceae, Caryophyllales), a new species from the northern Espinhaço Range of Minas Gerais, Brazil

Nordic Journal of Botany, EarlyView.
Guapira Aubl. (Nyctaginaceae, Pisonieae) comprises dioecious shrubs and trees widely distributed in the Neotropics and occupying diverse habitats. In the Brazilian Cerrado, the genus occurs in several phytophysiognomies, including Campos Rupestres, a montane rock ecosystem with high levels of endemism but still marked by significant gaps in botanical ...

Testing arbitrary classes of light in a physiognomically heterogeneous area of "campo rupestre" vegetation [PDF]

Anais da Academia Brasileira de Ciências, 2013
The Brazilian "campo rupestre" vegetation shows high light heterogeneity, characteristic which is often disregarded in ecophysiological studies due the difficult of obtaining accurate measurements in a complex environment. The aim of the present study it was to describe how much heterogeneous is the light distribution in this environment, as well as ...

Eriope barrinhae (Lamiaceae, Hyptidinae), a new montane species from northern Minas Gerais, Brazil

Nordic Journal of Botany, EarlyView.
In northern Minas Gerais, in the Monte Azul region, the Pico da Formosa mountain remains poorly explored botanically despite recent discoveries of new taxa. During fieldwork at the summit of this mountain, we discovered a distinctive population of Eriope that differs from all known species by a unique combination of morphological characters.

Determinant factors for epiphyte-phorophyte interactions in patches of cloud forest within a matrix of campos rupestres [PDF]

Acta Botânica Brasílica
The epiphytic flora is influenced by the architecture and morpho-physiology of phorophytes. Our knowledge about the ecology of these communities remains limited, especially in the campos rupestres.

Scientists’ warning on the global destruction of rock outcrop ecosystems

Conservation Biology, EarlyView.
Abstract Rock outcrops are geological formations that harbor a highly specialized biota adapted to harsh environmental conditions that differ from their surrounding landscapes. They are globally distributed, especially in old, highly weathered landscapes, and can function as habitat islands containing high levels of endemism and distinct evolutionary ...

Plant life in campo rupestre : New lessons from an ancient biodiversity hotspot [PDF]

Flora, 2018
The years 2011–2020 represent the United Nations Decade of Biodiversity, aiming to inspire worldwide actions to support biodiversity conservation. This Special Issue illustrates the current knowledge of plant life in campo rupestre, a megadiverse, highly-endemic vegetation complex, and one under alarming and unprecedented threats.

Assessing the evolutionary distinctiveness of a highly threatened plant group: The urgency to preserve a unique lineage of evolution in Brazil

PLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1223-1237, July 2026.
Brazil's diverse flora is under several threats, with many unique lineages facing extinction, particularly in biodiverse regions like the Cerrado and campo rupestre. This study sheds light on the conservation needs of Cambessedesia (Melastomataceae), an endemic genus with 95% of its species endangered, using an approach to rank and prioritise species ...

Vascular flora of campos rupestres: floristic composition, sampling effort and species richness

, 2017
Campos Rupestres are a azonal vegetation formed by phytophysiognomies predominantly herbaceous-shrub, prone to fire, including campos limpos, campos sujos, swamps, gallery forests, bushlands, cerrado rupestre and rock outcrops.
