| Biological knowledge is important for guidance of conservation polices. In the Cerrado, an extremely diverse biome, the last synthesis of floristic knowledge has more than ten years. To understand the progress on the information, our aim was quantify the tree species of the Cerrado, and assess their distribution. We compiled 167 inventories and rapid surveys of tree species, corresponding to 625 sites. We accessed the species distributions in the Brazilian biomes, and estimated the number of species in the savannas of Cerrado using four algorithms. We observed a greater local richness in more central regions of the biome, but due to high beta diversity, more peripheral regions presented a greater cumulative richness. The Atlantic Forest was the most... |

| ABSTRACT After a brief historical account of the genus, a new species, Marsypianthes tubulosa, from the Brazilian state of Tocantins is described and illustrated. The new species is similar to M. chamaedrys (Vahl) Kuntze, the most polymorphic species of the genus. It is distinguished from the other species of the genus by its habit and characters of the cyme, calyx and corolla. Comments on the taxonomy and distribution of the new species are provided, as well as a conservation assessment, distribution map, photographs and a black and white illustration. |

| Abstract: Bignoniaceae is a Pantropical plant family that includes 82 genera and 830 species of trees, lianas, and shrubs. The Tabebuia alliance (14 genera and 147 species) and tribe Jacarandeae (2 genera and 50 species) are both Neotropical and represent the largest clades of trees and shrubs in the family. Here, we present a taxonomic treatment for these two clades for the state of Pernambuco, Brazil. Overall, we documented 23 species distributed in seven genera, i.e., Cybistax Mart. ex Meisn., Godmania Hemsl., Jacaranda Juss., Handroanthus Mattos, Sparattosperma Mart. ex Meisner, Tabebuia Gomes ex DC., and Zeyheria Mart. Six taxa are new records for the state, i.e., Cybistax antisyphilitica (Mart.) Mart., Handroanthus capitatus (Bureau & K. Schum)... |

| Abstract Located in the municipalities of Ouro Preto and Mariana, in the Quadrilátero Ferrífero (QF) of Minas Gerais, the Itacolomi State Park (ISP) shelters more than 7,000 ha of remnants of Atlantic Forest and campos rupestres. The QF region has high biodiversity and is being highly impacted, mainly by mining activities. Aiming to organize the available floristic information and to support related research, this study presents the list of phanerogamic species of the ISP and the major vegetation types. This survey was carried out from October/1992 to July/2006, by monthly field trips. Besides authors´ personal collections, other records were assembled from herbarium databank. A total of 1623 taxons belonging to 122 families were listed. The families with... |
