E-mail: somlyay@bot.nhmus.bu Abstract - A single specimen of Epipactis futakii new to the flora of Hungary was found in the Pilis Mts (Pest county) in 2008. In 2009 four blooming specimens (representing three individuals) were detected at the same locality. The plant grew in a hornbeam-oak-beech forest rich in orchid taxa, of which Epipactis leptochila has not been published from the Pilis Mts yet. With two figures. Keywords - Epipactis futakii, Hungary, Orchidaceae, Pilis Mts. INTRODUCTION In 1998 a new Epipactis species, E. futakii MEREDA et POTÙCEK was described from Slovakia (MEREDA & POTÛCEK 1998). Epipactis futakii is an obligate autogamous taxon, which is reflected in its floral morphology (see HOLLINGSWORTH et al. 2006): during anthesis the flowers always remain pendulous and closed. In fact, E. futakii is the only known Epipactis species that forms cleistogamic flowers exclusively. Although the rostellum is present and persistent, it is functional only initially. The epichil is triangular and acute, greenish with a pair of whitish calli near its base. An additional diagnostic feature of the species is the unique colour of the flower: the base of tepals becomes violet while the rest remains green (MEREDA & POTÚCEK 1998, VLCKO etal. 2003). The species has only been recorded from only five regions of Slovakia so far: Male Karpaty Mts, Povazsky Inovec Mts, Strázovské vrchy Mts, Biele Karpaty Mts and from the boundary of Revúcka vrchovina and Ostrôzky - near Ruziná (MEREDA & POTÚCEK 1998, PERNY & MEREDA 2000, H RIVNÁK et al. 2005, M EREDA 2010, JA NSKY 2010).
