Biogeomorphological evolution of rocky hillslopes driven by roots in campos rupestres, Brazil

Geomorphology, 2021
Abstract The campos rupestres (rocky grassland) comprise an old-growth seasonally dry herbaceous ecosystem on mountaintops in central and eastern Brazil and in disjoint areas with sparse shrubs with high plant diversity and endemism. This ecosystem consists of sharp-edged quartzite landforms and rocky hillslopes with boulders, blocks, and sparse soil

Utricularia biceps (Lentibulariaceae), a new carnivorous species endemic to the campos rupestres of Brazil

Phytotaxa, 2018
Utricularia biceps (Lentibulariaceae), a new species belonging to U. sect. Foliosa, is here described and illustrated. This new species is endemic to the campos rupestres of eastern Brazil, an extremely biodiverse and endangered vegetation. Notes on phenology, ecology, habitat, and conservation are provided, along with a discussion on the features that

Vegetation of Brazilian campos rupestres on siliceous substrates and their global analogues

Flora, 2018
Abstract Campos rupestres (on quartzite substrates) are an enigmatic habitat mosaic characterised by nutrient-poor (mainly phosphorus-deprived) soils and supporting grassland and scrub. They occur at high elevations of some mountain ranges of several eastern and central Brazilian states.

Actinocephalus verae (Eriocaulaceae), a new species from the Brazilian Campos Rupestres

Brittonia, 2010
We describe and illustrate the new species Actinocephalus verae (Eriocaulaceae: Paepalanthoideae). This species is endemic to the rocky outcrops of the Espinhaco range in Minas Gerais, Brazil. We make comparisons with Actinocephalus ithyphyllus and Actinocephalus ochrocephalus, the morphologically most similar species.

Three new species of Ocotea (Lauraceae) from the campos rupestres of Brazil

Brittonia, 2010
Three new hermaphrodite species of Ocotea (Lauraceae) from the campos rupestres of Brazil are described and illustrated: Ocotea pumila, which is known from Bahia state; and Ocotea colophanthera and Ocotea rupestris both from Minas Gerais state. Their diagnostic features are pointed out, and a discussion of their relationships to other species of Ocotea
