Two spikes of this rather beige plant are now visible at the known site on Ashdown Forest. Both its common and scientific names refer to the supposedly nest-like appearance of the roots. Though xanthophyll and chlorophyll a have been reported in it (but not chlorophyll b), it is a plant species that does not photosynthesise, instead gaining its energy as a result of a myco-heterotrophic relationship with mycorrhizal fungi in the soil, which are in the family Sebacinaceae.
Given the binomial Ophrys nidus-avis by Linnaeus, it was given its current preferred name Neottia nidus-avis by the French botanist Louis Claude Richard (1754-1821), the author of De Orchideis europaeis (1817).
