 Predominance of species varies according to the different soil types.Grasses typically occur in sandy soils, with many species from the graminoid families Cyperaceae, Poaceae and Eriocaulaceae, whereas the rocky outcrops are usually dominated by orchids, bromeliads and species of Clusiaceae and Velloziaceae.The List of Species of the Brazilian Flora published in 2015 around 5000 plant species for the "campo rupestre;" according to REFLORA by 2019 this number has currently increased in about 100 species, if the database is queried for plants occurring in "Highland Rocky Field".
