Abstract
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.
Highlights
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 (Lohmann & Ulloa, 2007; Judd et al, 2009)
Given the significant rate of endemism and diversity for the Caatinga biome, and the limited number of surveys for the family therein, this study aims to contribute to a better understand of the Bignoniaceae in the Caatinga
The Evironmental Protection Area Serra Branca, Raso da Catarina (EPASB, Figure 1) comprises 67,237 ha, located in the municipality of Jeremoabo in Northeastern, in the State of Bahia, and it is fully inserted into the “polígono das secas” (Fundação CTI/NE, 2016), delimited by the coordinates 09o53’15.5’’ to 09o44’34.6’’S and 38o49’36.1’’ to 38o52’20.4’’W, limited to the South with the VazaBarris River and North to the Ecological Station Raso da Catarina (ESRC)
Summary
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 (Lohmann & Ulloa, 2007; Judd et al, 2009). 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 (Lohmann, 2015). 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) recognized 26 species in their taxonomic treatment of the Tabebuia Alliance
