| We describe the floristic composition of the tree-shrub vegetation in 10 areas of rocky outcrop cerrado in Goiás State, Brazil. Ten 20×50m plots (totaling 1ha) were established and all of the individuals with diameters at 30cm above soil level (DB30) ³5cm were included in the sampling. Comparative analyses of the flora were realized using similarity indices (Sørensen and Czekanowski), classification analysis (TWINSPAN), and the Mantel test. A total of 13,041 tree-shrub individuals were sampled, distributed among 219 species, 129 genera and 55 families. Fabaceae was the most well-represented family, followed by Myrtaceae, Melastomataceae, Vochysiaceae, Malphigiaceae, and Rubiaceae. Fully 42.3% of the comparisons evaluated by the Sørensen index were... |

| The present study analyzed the influence of edaphic variables on the floristic compositions and structures of the arboreal and shrub vegetation of typical cerrado (TC) and rocky outcrop cerrado (RC) communities in the Serra Negra mountain range in Piranhas Municipality, Goiás State, Brazil. Ten 20×50m plots were established in each community, and all individuals with minimum diameters ³5cm measured at 30cm above soil level were sampled. Composite soil samples were collected at 0-20cm depths in each plot for physical and chemical analyses. The proportions of above-ground rock cover work also estimated in each RC plot. A total of 2,009 individuals (83 species, 69 genera, and 34 families) were recorded. Qualea parviflora was the only species consistently... |

| Bromeliaceae is one of the most relevant taxonomic groups of the Atlantic Forest, where the Brazilian southeastern region stands out as a center of diversity and endemism for many taxa of the family. We present a checklist of the 12 genera and 44 species of Bromeliaceae from the Pedra dos Pontões, in Mimoso do Sul municipality, Espírito Santo state, southeastern Brazil. The Bromelioideae (22 species) was the subfamily with most taxonomic diversity, followed by Tillandsioideae (18 species) and Pitcairnioideae (four species). We also report the first occurrence of four species (A. squarrosa, N. antoineanum, V. pseudoatra and V. pardalina) for the Espírito Santo state. Almost half of the taxa surveyed inhabit exclusively the vegetation associated to the rocky... |
