Tongue orchids are terrestrial herbs with one to a few stalked leaves at the base of the flowering stem, or leafless. One to a few dull coloured flowers are borne on an erect flowering stem. The most conspicuous part of the flower is the labellum, compared to the much reduced sepals and petals. At least some species are pollinated by wasps when they attempt to mate with the flower. There are about twenty five species found in South Asia, Southeast Asia and the South Pacific.

The dorsal sepal and petals overlap and form a hood over the column and there is a deep pouch at the base of the labellum. They are found in tropical regions from northern India through Southeast Asia, China, Japan to Australia and some Pacific Islands.
