'''''Gymnadenia''''' is a [[genus]] in the orchid family (Orchidaceae) containing 22 [[terrestrial plant|terrestrial]] [[species]].

They can be found in damp [[meadow]]s, [[fen]]s and [[marsh]]es, and on chalk or limestone, often in alpine regions of [[Europe]] and [[Asia]] up to the Himalayas. The Fragrant Orchid (''[[Gymnadenia conopsea]]'') has been introduced into the [[USA]].

These hardy terrestrial [[orchids]] are [[deciduous]]. They survive the winter through their [[corm]]s, two deep-cut tubers (more like [[tuberous root]]s). Long lanceolate [[green]] [[Leaf|leaves]] grow at the bottom of the [[Plant stem|stem]]. There are some small leaves at the stop of the stem.

They [[flower]] during the [[summer]]. The [[inflorescence]] is a dense cylindrical spike between 5 and 30 cm long. It can consists of up to 150 small pleasant-smelling [[flowers]]. Their color can vary from pale purple to pink and [[white]]. The [[labellum|lip]] is wide with three lobes. The marginal [[petal]]s are horizontal. There is a long, thin, threadlike spur.

Several [[species]] were formerly classified under ''Nigritella''.
