Arethusa bulbosa, commonly called Dragon's Mouth Orchid, is the only species in the orchid genus Arethusa. The genus is named after a naiad of Greek mythology. This monotypic genus is abbreviated Aret in trade journals.

This terrestrial and rare orchid occurs Eastern North America from Manitoba east to Newfoundland and St. Pierre & Miquelon south to Virginia, with isolated populations in northern Saskatchewan and in the Carolinas. It occurs in bogs, swamps and other wet lowlands. It grows to a height of 15 cm. It forms a large, single, pink terminal flower, with a showy lip and white and yellow fringed crests.
