|Type:||epiphytic, terrestrial, or even lithophytic|
|Size:||quite varied in flower size and appearance; apical, lateral or basal flowers are mostly small to medium in size and often are not marked by a conspicuous display; inflorescences are frequently dense|
|Flowering:||grow in tufts, in racemose inflorescences, sometimes in corymbs or panicles; many species are fragrant; flowers may be produced only once, or during several years from same or new inflorescences|

|Known for:||common name Reed-Stem Orchid; large and showy inflorescences; fringed lip of some species; long-lasting flowers; can be very aggressive colonizers of disturbed habitat, and many species which were once rare have become more common as the result of human activities|
|History:||genus name (from Greek epi and dendron, "upon trees") refers to its epiphytic growth habit; Carl Linnaeus named this genus in 1763|
