Rubiaceae na flora aquática e palustre do Recôncavo da Bahia

Abstract

Aquatic plants or palustris are those that have the ability to withstand the permanent or periodic submersion of the whole plant or part of it, such as the roots. Rubiaceae has cosmopolitan distribution and is present in all phytogeographic domain in Brazil. Although rich in Bahia, there are few floristic and taxonomic studies with an emphasis on Rubiaceae in the state. As far as the region of the Recôncavo of Bahia is concerned, there are no family-oriented studies so far, especially regarding the occurrence of species in aquatic and marsh environments. By than, the objective of this work is to study the aquatic and marsh flora of Rubiaceae in Recôncavo basin. A total of 30 field trips were carried out and a total of 317 specimens were collected, which were deposited in the Bahia Recôncavo Herbarium (HURB). Were found 12 species appurtenant to nine genera. The more representative genus were: Borreria G.Mey, three species, Borreria ocymifolia (Roem. & Schult.), Borreria scabiosoides Cham. & Schltdl., Borreria verticillata (L.) G. Mey) and Spermacoce L. two species, Spermacoce eryngioides (Cham. & Schltdl.) Kuntze., Spermacoce prostrata Aubl) beyond species, Diodia saponariifolia (Cham. & Schltdl.) K.Schum., Gonzalagunia dicocca Cham. & Schltdl., Hexasepalum apiculatum (Willd.) Delprete & J.H. Kirkbr., Mitracarpus baturitensis Sucre., Perama hirsuta Aubl., Richardia grandiflora (Cham. & Schltdl.) Steud and Sabicea grisea Cham. & Schltdl. This work represents an initial contribuition to the Rubiaceae Family knowledge on aquatic habitats of Recôncavo basin, creating data that can be used for posterior works over Family distribuiton. Are presented descriptions, comment and distribution maps, even as, key. This work is part of Guia de identificação de espécies aquáticas e palustres do Recôncavo da Bahia project.
