Abstract. Gˇvaudan, A.- Epipactis leptochila (Godfery) Godfery - Variability of French Alps and Jura populations, systematic and taxonomical reflections [Natural. belges 80 (Orchid. 12) (1999): 278-279, 343-371]. Epipactis leptochila variability is studied extensively in France from populations of the Alps and Jura mountains. With the help of systematic field observations and a detailed literature review, this taxon is delimited versus E. helleborine. Owing to the broad range of variation of the characters observed, the varietal rank is proposed for E. neglecta, considered till now as an independant species from the E. leptochila species group. New data on the repartition of both varieties of E. leptochila (var. leptochila and var. neglecta) are presented for 6 French departments (01: Ain, 25: Doubs, 38: Is¸re, 39: Jura, 73: Savoie, 74: Haute-Savoie).
