A relatively substantial Epipactis species, which is rather difficulty to distinguish from Epipactis helleborine. The lip of Epipactis leptochila is longer than broad and acuminate, characteristic is a wide v-shaped passage between hypochil and epichil. In addition, the species is autogamous. Viscidium is missing or inoperative, pollen crumble already at closed flower and lead to self pollination. In the case of adverse weather conditions, the species acts partly cleistogamous, just as in the case of the plants I found. The species preferrs (half-)shady beech forests – often situated on northern slopes.
