“…Giulietti, Conceição, and Queiroz (2006) considers Bignoniaceae to be the eighth most representative family of the Caatinga. Among the works carried out on taxa of Bignoniaceae in the Northeast Region of Brazil, we highlight the following: Harley and Simmons (1986) recorded three species in the region of Mucugê (Bahia); Gentry (1995) recorded six species at Pico das Almas, Chapada Diamantina; Lohmann and Pirani (1996) identified 17 species of the formerly tribe Tecomeae in the Cadeia do Espinhaço (Bahia and Minas Gerais); Silva and Queiroz (2003) recorded 33 species in Catolés, Chapada Diamantina, Bahia; Silva-Castro, Costa, and Brito (2007) recorded 15 species of Jacaranda in Bahia and Espírito Santo, Silva-Castro, and Rapini (2013) The Caatinga has a high rate of endemism and diversity, making a better understanding of its flora necessary for proper conservation measures (Prado, 2003). However, Caatinga is probably the most undervalued and poorly known botanically biome (Giulietti et al, 2002), yet is has the lowest number of conservation units and is one of the least protected in Brazil (Leal, Silva, Tabarelli, & Lacher, 2005).…”

Bignoniaceae comprises 82 genera and 827 species distributed mostly in tropical and subtropical regions, with a few species in temperate climates, and is most diverse in South America. The Brazil is the center of diversity for the group, with about 406 species in 33 genera, of which 22 genera and 90 species occur in the Caatinga. The floristic survey of Bignoniaceae in the Environmental Protection Area Serra Branca included analysis of 31 specimens collected from August 2009 to February 2012. The analyses were supplemented with dried collections from the following herbaria: ALCB, HRB and HUEFS. Nine genera and 11 species were recorded: [Anemopaegma Mart ex DC; Bignonia L.; Cuspidaria DC.; Fridericia Mart.; Handroanthus Mattos; Jacaranda Juss; Lundia DC.; Mansoa DC. and Tabebuia Gomes ex DC.]. Fridericia was the most representative genus with three species. The taxonomic treatment includes a key for the identification, descriptions, illustrations, photos, data of the geographical distribution, reproductive phenology and comments about the species.

O cenário atual das coleções botânicas do município de Vitória da Conquista, Bahia, Brasil é apresentado. As informações foram obtidas através de consultas a bancos de dados virtuais, referências bibliográficas e trabalhos de campo. Até o momento, a flora inclui 1.057 espécies distribuídas em 950 angiospermas, 38 pteridófitas (licófitas e samambaias) e 69 briófitas (musgos e hepáticas). Dentre estas, 36 espécies estão ameaçadas de extinção, 101 são novas ocorrências para a Bahia e seis endêmicas do município. Os dados aqui levantados demonstram a necessidade de aprofundar o conhecimento da diversidade florística do município de modo a direcionar as ações que visem a conservação da flora da região, por meio de coletas sistemáticas, melhoria na qualidade das identificações, enriquecimento das coleções botânicas e produção de monografias taxonômicas.

Leaf traits are good indicators of ecosystem functioning and can affect herbivory and leaf reflectance patterns, allowing a better understanding of changes in environmental conditions, such those observed during forest natural regeneration. The aim of this study was to evaluate the intraspecific variation in leaf traits and their influence on the pattern of herbivory and leaf reflectance in three species distributed along a successional gradient (early, intermediate and late stages) in a tropical dry forest (TDF) in northern Minas Gerais, Brazil. We sampled individuals of the following abundant tree species that occurred in multiple successional stages: Cenostigma pluviosum, Handroanthus ochraceus, and Tabebuia reticulata. We collected 10 leaves from each tree to determine the contents of chlorophyll a, b, and total, carotenoids and water, as well as the percentage of leaf area removed by herbivores and leaf specific mass (LSM). We also measured five spectral reflectance indices (Normalized Difference Vegetation Index-NDVI, Simple Ratio-SR, modified Normalized Difference-nND, modified SR-mSR and Water Index-WI) using a portable spectrometer. Our results showed intraspecific differences in most leaf traits along the successional gradient, suggesting that local adaptation may play an important role in plant community assembly. However, herbivory only differed for H. ochraceus in early and intermediate stages, but it was not affected by the leaf traits considered here. Spectral reflectance indices also differed among successional stage for all species together and for each species separately, except for T. reticulata in intermediate and late stages. Thus, leaf spectral signatures may be an important tool to the remote detection of different successional stages in TDFs, with implications for forest management.
