In the petrochemical park of Feluy (province of Hainaut, Wallonia,

edge of a birchwood form an interesting orchid site, noticed in June
2016. In June 2017, in an important population of Dactylorhiza fuchsii, the flowers of numerous individual, somewhat late-flowering, were more or less actinomorphic, as in the “lusus elabiata”, described from Switzerland. A bit later, in July, numerous Epipactis helleborine are in flowers at the same place. Amongst these, a third are spindly and possesse most of the morphological characters of E. helleborine var. helleborine f. minor.
