We report on observations of four native Epipactis species in the Lesse et Lomme region of southern Belgium. Their morphological and ecological traits are described and two hybrids between E. helleborine and E. purpurata on the one hand, E. muelleri, on the other hand, are discussed. Also presented is a singular plant, which we call “l’épipactis femelle » (the female helleborine), probably a hybrid between E. muelleri and E. neglecta, which is totally devoid of male reproductive parts. Finally, we briefly discuss the role of forests, coniferous as well as deciduous, in favouring the development and evolution of species such as the members of genus Epipactis that inhabit them.
