The Altipiani di Colfiorito are a system of seven tectonic depressions with karstic phenomena, located in the Umbria-Marches Apennine ridge (Italy). This area is characterized by the presence of wetlands which have been internationally protected through the institution of a Ramsar Site, an Important Bird Area, three Sites of Community Importance and a Special Protection Area. The analysis of bibliographic and herbarium data and the floristic field research carried out from 1999 to 2008, allowed to list 657 floristic units, belonging to 88 families and 320 genera. Among them, 11 (Avena sativa subsp. macrantha, A. sterilis subsp. ludoviciana, Chenopodium hybridum, Cuscuta campestris, Mentha arvensis, Rosa andegavensis, R. dumalis, Schedonorus uechtritzianus, Scrophularia umbrosa, Trifolium alexandrinum and Veronica catenata) are new for the Umbrian flora and 2 (Crypsis alopecuroides and Schedonorus uechtritzianus) for the Marchean flora. Numerous rare and threatened species in Umbrian and Marchean flora, such as Alopecurus bulbosus, Carex tomentosa, Equisetum fluviatile, Juncus hybridus, Nymphaea alba, Ophioglossum vulgatum, Ranunculus flammula, R. ophioglossifolius, Trifolium patens and Utricularia australis, have been found. Nevertheless some species, previously recorded for Palude di Colfiorito, such as Eriophorum latifolium, Hippuris vulgaris, Hydrocotyle vulgaris, Menyanthes trifoliata, Potamogeton lucens, P. trichoides, Ranunculus lingua and Triglochin palustre, were not found and considered locally extinct.

Abstract
The Altipiani di Colfiorito are a system of seven tectonic depressions with karstic phenomena, located in the Umbria-Marches Apennine ridge (Italy). This area is characterized by the presence of wetlands which have been internationally protected through the institution of a Ramsar Site, an Important Bird Area, three Sites of Community Importance and a Special Protection Area. The analysis of bibliographic and herbarium data and the floristic field research carried out from 1999 to 2008, allowed to list 657 floristic units, belonging to 88 families and 320 genera. Among them, 11 (Avena sativa subsp. macrantha, A. sterilis subsp. ludoviciana, Chenopodium hybridum, Cuscuta campestris, Mentha arvensis, Rosa andegavensis, R. dumalis, Schedonorus uechtritzianus, Scrophularia umbrosa, Trifolium alexandrinum and Veronica catenata) are new for the Umbrian flora and 2 (Crypsis alopecuroides and Schedonorus uechtritzianus) for the Marchean flora. Numerous rare and threatened species in Umbrian and Marchean flora, such as Alopecurus bulbosus, Carex tomentosa, Equisetum fluviatile, Juncus hybridus, Nymphaea alba, Ophioglossum vulgatum, Ranunculus flammula, R. ophioglossifolius, Trifolium patens and Utricularia australis, have been found. Nevertheless some species, previously recorded for Palude di Colfiorito, such as Eriophorum latifolium, Hippuris vulgaris, Hydrocotyle vulgaris, Menyanthes trifoliata, Potamogeton lucens, P. trichoides, Ranunculus lingua and Triglochin palustre, were not found and considered locally extinct.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
