Presence in France. See map below.

Height. Up to 40cm

There are no leaves - nutrition derived from a mycorrhizal fungus in the soil/litter, which in turn derives nutrition from the roots of trees.

Plants are generally beige-brown, though sometimes yellowish or white forms are discovered. The flower labellum splits and strongly diverges at its lower end.

The common names of this orchid in several languages, derive from a comparison of the tangled roots of the plant to a bird's nest.

Soil type. All, generally under a woodland canopy in deep leaf litter.
