Floristic and coenological data from the travertine substrates of the SAC “Travertini Acque Albule (Bagni di Tivoli)” (Lazio Region – Central Italy)

During a phytosociological field-work campaign on the vegetation of the travertine outcrops, included in the Special Area of Conservation (SAC) “Travertini Acque Albule (Bagni di Tivoli)” (Central Italy), several taxa of particular interest were identified. Carex vulpina, Lolium apenninum, Onosma echioides subsp. angustifolia, Typha domingensis, T. laxmannii and Vicia pannonica subsp. pannonica are new for the Lazio administrative Region, while Ophrys illyrica and Zannichellia peltata are confirmed for the flora of this Region. For each of these taxa phytosociological samples describing the plant communities in which they were found are provided. New records for rare species were also reported for cryptogams such as Algae, Lichens and Mosses.
