Notulae sulla flora del Parco Nazionale delle Foreste Casentinesi, Monte Falterona e Campigna (Appennino tosco-romagnolo) - 4: novità tassonomiche e distributive sulle orchidee del Parco

Following the ongoing work of updating the flora check-list of the Park, the orchid contingent of this territory has been reconsidered in the light of unpublished data owned by the experts of the G.I.R.O.S. (Gruppo Italiano per la Ricerca sulle Orchidee Spontanee) and of recent systematic works that produced distributional and nomenclatural updates. The novelties are presented here: Epipactis placentina Bongiorni & Grünanger was found to be new for the Park and is reported here for the first time; Ophrys romolinii Soca is the taxon of sect. Bertoloniorum present in the area, to which all previous O. bertolonii Moretti reports must be attributed; Ophrys appennina Romolini & Soca is the taxon of sect. Fuciflorae present in the area, to which all previous O. fuciflora (F. W. Schmidt) Moench. reports must be attributed; for other already known entities we clarified which subspecies is present, while for some rare species we added new sites.
