Mulino di Tifo wetland: One biotope of notable botanical interest in Val di Farma (Siena, southern Tuscany) [L'area umida del Mulino di Tifo: un biotopo di notevole interesse botanico in Val di Farma (Siena, Toscana meridionale)]

Authors describe the swampy resurgent zone of Mulino di Tifo in Val di Farma, a limited size area, recently discovered, but very interesting from botanical point of view. The vegetational analisys has been carried out through phytosociological relevés referred to different syntaxonomical units. The analisys was mainly focused on the most important hydrohygrophilous vegetational type, paying particular attention to priority habitats (Cladietum marisci) and environments of community interest (herbaceous coenoses of Isoëto-Nanojuncetea and of Bidentetea and woods of Alnetea glutinosae). In the biotope there are some species rare in Tuscany and in the most part of the italian peninsula such as Cladium mariscus, Thelypteris palustris and Osmunda regalis. The floristical research is summarized in the list and in the biological and chorological spectrum. The survey has been integrated with some comments and indications for the conservation of this wetland. © 2018 Società Botanica Italiana onlus.
