Nigritella are high altitude orchids only. They can be found in the Massif Central or the Jura for the lowest altitudes but abundantly in the Alps and also in the Pyrenees.

Differentiating the species will be a complicated task because even within a station we will find plants with more or less conical or round spikes, more or less elongated. The coloring is generally purple as for many high altitude plants. All species have a more or less pronounced smell of vanilla.

It will therefore be necessary to rely on specialized works to find distinctive signs in the shape of the labella and bracts.

This species is found only in the Alps. It displays a pink coloration at the bottom of the inflorescence and bracts longer than the latter.
