E. distans
was first described from Drome, France by C Arvet-Touvet in 1872 and
its name literally means "differing from others". This species is
all but endemic to France, although it creeps across the Italian border
in the region of Briancon, where as with the French populations,
it inhabits alpine
valleys up to an altitude of around 2200 metres.
E. distans
is a plant of the western Alps and will grow in
either sun or light shade on primarily sedimentary or calcareous soils,
particularly scree slopes that are regularly flushed with mountain run off. In France it's distribution takes
in Haute-Savoie and from Isere to Alpes-de-Haute-Provence,
together with a small number of isolated outposts in the Massif
Central. Although this species has a quite specialized habitat
requirement, its not a rarity and
can in fact be abundant in its favoured sites. Until 2004 the
range of E. distans
included stations in the central massif region of Spain
but studies by Delforge concluded this population
was in fact a
distinct species and re-described
as E. molochina. This reclassification has not
however met with the universal concurrence of all botanical opinion.
E. distans is not a particularly striking Epipactis
and its relatively early flowering and distinctive habitat serve to differentiate it from other
similar members of the genus. A further and very significant
identification feature is as can be seen from the photographs, the obviously one
sided nature of the inflorescence.
The pictures come from
Drome, France and date from the first week of July.
