Phytophysiognomic differences between Cerrado Rupestre and Campo Rupestre. Although they can occur in mosaics on rocky outcrops, both on quartzitic soils (A and B) and on canga (ferruginous soils, C and D), the Cerrado Rupestre is a savannah phytophysiognomy and presents a tree cover between 5 and 20%, while the Campo Rupestre is a grassland phytophysiognomy, with a predominance of a herbaceous-shrubby stratum with less than 5% tree cover A Cerrado Rupestre over quartzitic soil in the Municipality of Congonhas, Minas Gerais, Brazil B Campo Rupestre over quartzitic soil in Serra do Ouro Branco State Park, Ouro Branco, Minas Gerais, Brazil.
