Solanaceae na flora aquática e palustre do Recôncavo da Bahia

Abstract

Plants with continuous or periodic submersion capacity, of at least the root system are considered aquatic and marsh. This characteristic allows vegetables to occupy humid environments, for at least some periods of year. Part of these plants are Solanaceae, a family that has a cosmopolitan distribution, with about 97 genera and 2700 species, some of them occupy humid environments. This Family shows wide distribution in the country, occurring in all phytogeographic domains. This work aimed to carry out a survey of Solanaceae species of aquatic and marsh environments in the Recôncavo of Bahia Region, as well as do morphological studies about this Family. The botany material collected was in different municipalities in Recôncavo of Bahia, between 2009 and 2019. The study material was duly georeferenced, herborized according to standard literature and, subsequently deposited in Herbarium of Reconcavo of Bahia (HURB). To identify the material, treatments and recent reviews were used, in adittion to morphological characters analysis. 14 species distributed in five genera were registered. The collected and studied species were Capsicum sp., Cestrum nocturnum, Phisalys angulata, Schwenckia americana, S. molissima, Solanum americanum, S. fernandesii, S. palinacanthum, paniculatum, S. polytrichum, S. stramoniifolium, S. thomasiifolium, S. torvum and S. viarum. Descriptions, illustrations, and comments about the diagnostic characters were made to occurring species identification, as well as distribution maps on the study area. Solanum is the most represented genera in the area. The data obtained until now are very important to elaborate conservation strategies of these environments and contribute with the taxonomy of the present groups in these freshwater ecosystems.
