Faboideae na flora aquática e palustre do Recôncavo da Bahia

Abstract

Aquatic and marsh plants are characterized as vegetables that occupy since palustrine environment to actually aquatic environment. The Faboideae (Papilionoideae) subfamily gathers more than half of Fabaceae representatives, with 14,000 species belong to 503 genera and 29 tribes. The goal of this work was to realize a taxonomic treatment of Faboideae species occurring in aquatic and marsh environments of Recôncavo da Bahia region. To reach this objective, a taxonomic study was carried out through analysis of collections housed in the Universidade do Recôncavo da Bahia herbarium (HURB). These samples were collected in lakes, lagoons, and swamps of Recôncavo da Bahia region. On study were found nineteen species, grouped in ten genera of Faboideae. Aeschynomene L., Desmodium Desv. E Stylosanthes Sw. were the most representative genera, each one with four species. The remain genera: Calopogonium Benth., Crotalaria L., Dioclea Kunth., Macroptilium Benth., Rhynchosia L., Vigna Savi., and Zornia J.F. Gmel., were represented by only one species each. Aeschynomene scabra G.Don presents the widest distribution in the region . The characters such as: leaf and stipule morphology, inflorescence organization, color and shape of standard and keel, as well as fruit shape were important to the establishment of each taxa and to elaboration of taxonomic keys of these species.
