Bletilla, commonly named the urn orchid, is a temperate, terrestrial genus of orchids. The genus currently contains five recognized species distributed through China, Japan, Taiwan, south to Vietnam, Thailand and Myanmar. The name is actually a diminutive of Bletia because of the resemblance between the two genera even though Bletia is a New World genus. The genera Jimensia Raf. and Polytoma Lour. ex Gomes are generally included into Bletilla. This genus is abbreviated Ble in trade journals.
