Tainia, commonly known as ribbon orchids[3] or 带唇兰属 (dai chun lan shu)[4] is a genus of about thirty species of evergreen, terrestrial orchids in the (family Orchidaceae) distributed from India, China, Japan, Southeast Asia to New Guinea, the Solomon Islands and Queensland.

[1] Orchids in the genus Tainia are evergreen, terrestrial herbaceous plants with upright, crowded, thin fleshy pseudobulbs.

[3][4][5] The genus Tainia was first formally described in 1825 by Carl Ludwig Blume who published the description in Bijdragen tot de flora van Nederlandsch Indië.

[1][6][7] The name Tainia is an Ancient Greek word meaning "ribbon", "fillet", "band" or "stripe"[8] but Blume's reason for giving this name is not known.

They are found in Sri Lanka, India and Japan, then south from Myanmar to New Guinea, Australia and some Pacific Islands.
