The author reports on the find of a population of Epipactis muelleri Godf. in the extreme south of the Dutch province of Limburg. Only one specimen of this species has been found in the Netherlands before, viz. in 1945 in the same region (fig. 3). On the locality mentioned E. muelleri was found for the first time in 1971. In 1975 the station was visited again and about 10 specimens were observed. Phytosociological and ecological investigation of the site will be carried out in the future.
