Epipactis muelleri was first described from Alpes-Maritimes, France by Godfery in 1918 and is named after the eminent German botanist Herr F. Muller. It is commonly called the Mueller’s Helleborine.

This is a central European species which ranges from Belgium through to the former Czechoslovakia in the east. It was once thought to be present in the northeast of Spain.

A further distinguishing characteristic of E. muelleri is the hypochile colouration which tends to be rather more reddish than the brown of E. helleborine of which it often associates.

For a member of the Epipactis genus, E. muelleri is a relatively early species and can be in flower by mid June. The pictures here date from the last week of June and come from Barcelona province of northeast Spain.
