Androcorys is a genus in the family of the Orchid Family ( Orchidaceae). Ten species of these small, herbaceous plants are native to East Asia.
Description
To Androcorys include perennial herbaceous plant with roundish, hairy tubers as Überdauerungsorganen ( geophytes ). At shoot a sitting, rarely two leaves. The blade is narrow oval, the leaf base includes the stems.
The terminal inflorescence is a raceme. The small flowers are 'upside, yellowish or green. The bracts are small, scale-like. The ovary is sessile, fusiform and twisted.

The two club-shaped pollinia are of mealy consistency, in small portions together adherent. They sit without stalks directly to the viscid discs ( Viscidium ). The separation between scar tissue and stamen is triangular.
Dissemination
Androcorys is widespread along the southern slope of the Himalaya to southern China, Androcorys pusillus has a disjoint area that includes Japan and Taiwan. The " Flora of China " lists five species which occur in China, three of which are endemic there.
The species usually occur in alpine grasslands, at 5500 meters, they are among the orchids with the highest locations.
Systematics and botanical history
Within the genus of orchids Androcorys is classified in the tribe Orchideae. The limits to the closely related genus Herminium whose borders Peristylus that can be difficult to distinguish from Habenaria are unclear.
Androcorys was first described in 1919 by Rudolf Schlechter. The name derives from the Greek ἀνδρό Foreword - andro, Male ' and the Greek word κόρυς Korys, helmet ', since the petals are helmet-shaped above the stamen.
