According to some authorities
Gymnadenia nigra is endemic to Scandinavia and the alpine taxon is
Gymnadenia rhellicani (Teppner & E.Klein) Teppner & E.Klein
Thanks Martin - It does get complicated!
Ispot seems to still link to Nigritella nigra which is what mine and one other were posted as, whereas I see your post is
named Gymnadenia nigra
but as you state my same sighting when added to Tela-Botanica is classed as Gymnadenia rhellicani (Teppner & E.Klein) Teppner & E.Klein.
I still don't understand who decides to change the names because I have found that they use a lot of different Latin names in France.
