'''''Lechanorchis''''' is a genus of orchids (family [[Orchidaceae]]) belonging to the subfamily [[Vanilloideae]].

The scientific name is derived from the Greek words ''lekane'' (basin) and ''orchis'' (orchid).

They occur in mountain forest of the Himalayas, tropical and subtropical Asia, New Guinea and some Pacific islands at altitudes between 300 – 1500 m

They are terrestrial, leafless myco-heterotrophs (formerly called saprophytes). They produce numerous, long, thick, horizontal roots under a short [[rhizome]]. The erect, dark, branched or unbranched [[Plant stem|stems]] are thin and brittle. They bear few to many dull brown, purple, yellow or green [[flower]]s with a somewhat brighter [[labellum|lip]]. The lip is about of equal length to the [[sepal]]s and is covered with dense, yellow hair.

Characteristic for this species is:
*the presence of a calyculus, a group of cup-like small [[bract]]s.
*the erect gynostemium (the fused [[stamen]] and [[pistil]]) is elongate.
