Titel: Orchis or anacamptis?

Came across such a plant today.

Location: Muhu, Estonia
Fully developed leaf rosette in the beginning of September, growing on a dry slope (very thin soil on top of a limestone).
No spots on the leaves.

There are following orchids growing in this area:
O.militaris
O.mascula
N.ustulata
Oph.insectifera
G.conopsea
G.densiflora

The app that I sometimes use for plant identification said "Himantoglossum" but no himantoglossums in Estonia.

First I thought it being O.militaris but the leaves on the plant are very low to the ground, not pointing upwards.

Orchis mascula or Orchis militaris I guess. The leaves are too wide and large for the other species.

None of the species you listed should have such a big rosette right now. O. mascula could look like that in late February or March and O. militaris even later in April.
My guess is that it is some kind of Gentianaceae. Probably a young G. cruciata.
The leaves in the first picture look a bit yellowish maybe because its growing period ends soon.

We do have gentiana cruciata here, so it's a possibility indeed.

I also stumbled upon a couple of pics of D.viridis where the leaves have kind of the same colours and "veins" on the back of the leaf.
But D.viridis is extremely rare in Estonia and I've never seen it in nature.

D. viridis does not have green leaves this time of the year. Dactylorhiza never make a winter rosette. I am pretty sure this is G. cruciata or some other Gentianaceae.

I think you are right about G.cruciata.
The leaves indeed look almost identical  :thumb
