| Raso da Catarina is one of the eight Ecoregions recognized for the Caatinga biome. This work includes the taxonomic study of Boraginales Juss. ex Bercht. & J.Presl in the Ecoregion Raso da Catarina, Bahia state, Brazil. The samples analyzed were collected from March 2009 to July 2013. The analyses were supplemented with dried collections kept in the herbaria: ALCB, IPA, HRB, HST, HTSA, HUEFS, HVASF, PEUFR and UFP. Two families, five genera and 16 species were recorded. The Cordiaceae family was represented by genera Cordia L. [C. glabrata (Mart.) A.DC., C. rufescens A.DC., C. superba Cham. and C. trichotoma (Vell.) Arráb. exSteud.] and Varronia P.Browne [V. curassavica Jacq., V. globosa Jacq., V. leucocephala (Moric.) J.S.Mill. and V. leucomalloides... |

| Aspidosperma Mart. is one of the most important genera from Apocynaceae Juss. occurring in Brazil. It is present in many plant formations and has species with both medicinal and economic value. From a taxonomic point of view, many of its species are difficult to identify, especially those occurring in the Amazonian region. In order to complement the information already available with regard to the taxonomy and distribution of the genus, the goal of this work was to provide a taxonomic study of the Aspidosperma species occurring in the state of Pará, northern Brazil. This study was based on the analysis of vouchers from the BHCB, HBRA, IAC, IAN, INPA, MG, R, RB and UEC herbaria, as well as scanned images of vouchers from Brazilian and foreign herbaria, and... |

| This study aims to evaluate the richness of the Papilionoideae species found in the Parque Estadual das Várzeas do Rio Ivinhema (PEVRI), which is located in the southeast region of Mato Grosso do Sul, Brazil, and investigate if the habits of this Leguminosae group vary in different formations of the park. Monthly collections, including all habits, were made by walking along pre-established trails, from September 2004 to September 2009. The PEVRI includes Seasonal Semideciduous Forest, Seasonal Alluvial Semideciduous Forest and fields. Twenty-three species distributed in 16 genera and 5 tribes were recorded. Phaseoleae was noted with 7 genera, followed by Dalbergieae with 6 genera and Desmodieae, Indigofereae and Crotalarieae with only 1 genus in each... |

| Abstract: Bernardia and Tragia are genera of the subfamily Acalyphoideae, with species occurring in tropical and subtropical regions. Studies concerning those genera are scarce in Brazil, including Northeastern Brazil. The present study was designed to study the taxonomy of species occurring there, and provides illustrations, keys, descriptions, and comments concerning taxonomic affinities, as well as information concerning their geographic distributions and environmental preferences. A total of 13 species were encountered, eight of Bernardia and five of Tragia. Of those, B. hamadryadica and T. cearensis are endemic to Northeastern Brazil and B. celastrinea, B. pulchella, and T. chlorocaulon are new records for the region. The two genera occur in moist... |

| Phytosociological structure was studied in limestone mining quarries at Rio Claro, São Paulo, Brazil. Quarries presented a chronosequence, ranging 1 to 40 years old, with focus on vegetation community organization, floristic similarity and plant diversity of three areas in different successive stages, devastated by limestone mining. A total of 1957 individuals distributed in 32 botanical families and 91 species were sampled. Low species diversity was obtained, ranged among quarries ages. In the early-established quarries, Leguminosae, Malvaceae and Sterculiaceae were the families most representative in number of species, while for the age 27, Asteraceae and Poaceae were the most representative. Diversity indices indicated that species diversity changed... |
