Floristic diversity of Rubiaceae on the Serra da Fumaça - Mountains complex of Jacobina, Bahia, Brazil

Abstract

This paper is a survey of Rubiaceae species found in the Serra da Fumaça - Mountains Complex of Jacobina, Bahia. In the period of Juny/2011 until August/2012 were taken monthly from botanical material along trails and in the forest contemplating all vegetation types in the area. We recorded 36 species in 20 genera. The most representative in number of species were Borreria G.Mey. (5 spp.), Diodella Small,Mitracarpus Zucc. ex Schult. & Schult.f. andPsychotria L. (3 spp. each), followed by CoccocypselumP.Browne, Declieuxia Kunth, Palicourea Aubl.,Perama Aubl., Richardia L. and Staelia Cham. & Schltdl. (2 spp. each). The other genera were represented only by one species:Cordiera elliptica (Cham.) Kuntze, Coutarea hexandra(Jacq.) K.Schum., Emmeorhiza umbellata (Spreng.) K.Schum.,Genipa americana L. Guettarda sericea Müll.Arg.,Malanea macrophylla Bartl. ex Griseb., Manettia cordifolia Mart.,Posoqueria latifolia (Rudge) Roem. & Schult., Sabicea grisea Cham. & Schltdl. and Tocoyena formosa (Cham. & Schltdl.) K.Schum.). Two endemic species were recorded, one of the Chapada Diamantina (Perama harleyi J.H.Kirkbr. & Steyerm.) and one of caatinga (Guettarda sericea Müll Arg.). Psychotria jambosioides Schltdl. and P. mapourioides DC. were recorded for the first time to the Espinhaço Range, both known only from the Atlantic coast. Identification key to the species, descriptions, illustrations and information on the geographical distribution of species and phenological data are displayed.
