Breitblättrige Stendelwurz
"Epipactis helleborine" var. "youngiana" was discovered in 1975 by Tony Porter, and described as a new species by Porter and A. J. Richards in 1982. The specific epithet commemorates Donald Peter Young, who worked extensively on "Epipactis". It is part of the "Epipactis helleborine" species complex, and cannot be distinguished from the wide-ranging and variable species "E. helleborine" using genetic markers. It is therefore treated as a variety of the widespread species, as "E. helleborine" var. "youngiana".
