Rubiaceae na Serra Geral de Licínio de Almeida, Bahia, Brasil

Abstract

One of the areas in Bahia that is known by the lack of floristic inventories is the southwest region, more precisely the area that comprises the septentrional part of the Espinhaço Range. The aim of this study was to carry out a floristic and taxonomic survey of Rubiaceae of the Serra Geral of Licínio de Almeida (SGLA), Bahia. Ten field trips were conducted between July 2012 and May 2015, covering all existing vegetation types in the area. The collected material was processed and deposited at HUEFS and ALCB herbaria. Reference materials were also analyzed in visits to CEPEC, HRB, HUEFS, RB and SPF. A number of 43 species distributed in 28 genera were recognized, with Declieuxia (5 spp.), Borreria (3 spp.), Cordiera (3 spp.) and Psychotria (3 spp.) as the most diverse genera. Following previous floristic studies in the Espinhaço Range, there is alarge number of genera (19) represented by a single species. Psyllocarpus asparagoides, Psyllocarpus laricoides and Stachyarrhena reflexa are endemic to Minas Gerais and Bahia; Declieuxia passerina and Galianthe peruviana are new records for Bahia, and two species are considered new for science (Randia sp. and Staelia sp.). Keys to genera and species identification, descriptions, taxonomic and biologic comments for all species are presented, as well as images and illustrations.
