Taxonomic notes on genus Nitella C. Agardh (Characeae) from the Metropolitan Region of Feira de Santana, Bahia State, Brazil

ABSTRACT

From a floristic study of the Family Characeae in the Metropolitan Region of Feira de Santana, Bahia State, we detected four species of Nitella, of which two are new additions for that state: N. axillaris, and N. praelonga, the latter being, of rare occurrence in Brazil, reported for the first time for the northeastern Brazil. The materials were analyzed using photonic and scanning electron microscopy. For all these species we provide descriptions, information on habitat, geographic distribution in Brazil and taxonomic notes.
