Neottia nidus-avis, the bird's-nest orchid, is a non-photosynthetic orchid, native to Europe, Russia and some parts of the Middle East.
Cypripedium acaule is a species of flowering plant in the orchid family Orchidaceae. It is commonly referred to as the pink lady's slipper or moccasin flower. The specific epithet acaule means "lacking an obvious stem", a reference to its short underground stem, for which reason the plant is also known as the stemless lady's-slipper. It is the provincial flower of Prince Edward Island, Canada and the state wildflower of New Hampshire, United States.
Neottia ovata, the common twayblade or eggleaf twayblade, is a terrestrial orchid widespread across much of Europe and Asia
Galearis spectabilis, commonly known as showy orchis or showy orchid, is an orchid species of the genus Galearis. It is native to eastern Canada and much of the eastern half of the United States.
Neottia cordata, the lesser twayblade or heartleaf twayblade, is an orchid of upland bogs and mires that rarely exceeds 15 cm (5.9 in) in height. It was formerly placed in the genus Listera, but molecular phylogenetic studies have shown that Neottia nidus-avis, the bird's-nest orchid, evolved within the same group.
Platanthera blephariglottis, commonly known as the white fringed orchid or white-fringed orchis, is a species of orchid of the genus Platanthera. It is considered to be an endangered species in Connecticut and Ohio, a threatened species in Florida, Maryland and Rhode Island, exploitably vulnerable in New York, and susceptible to be threatened in Québec.
Spiranthes romanzoffiana, commonly known as hooded lady's tresses or Irish lady's-tresses, is a species of orchid. Collected by Chamisso during the Romanzov expedition it was described by him in 1828 and named for Count Nikolay Rumyantsev who financed the expedition.

Neottia is a genus of orchids. The genus now includes the former genus Listera, commonly known as twayblades referring to the single pair of opposite leaves at the base of the flowering stem.

Scrophularia umbrosa, the green figwort, is a perennial herbaceous plant found in Europe and Asia. It grows in moist and cultivated waste ground.
Neottia banksiana is a species of orchid known by the common name northwestern twayblade. It was formerly placed in the genus Listera, but molecular phylogenetic studies have shown that Neottia nidus-avis, the bird's-nest orchid, evolved within the clade formerly containing only Listera species, so all species of Listera have been formally moved to Neottia, the older genus. Some continue to refer to this species by its previous genus; older scientific names include Listera banksiana and Listera caurina.
Neottia convallarioides is a species of orchid known by the common names broad-lipped twayblade and broad-leaved twayblade. It was formerly placed in the genus Listera, but molecular phylogenetic studies have shown that Neottia nidus-avis, the bird's-nest orchid, evolved within the same group, and all species of Listera have been moved to Neottia.
Cypripedium arietinum, the ram's head lady's slipper, is a rare orchid that grows in lightly shaded areas with calcareous soils. It is characteristic of the alvars around the Great Lakes in North America, as well as in New England. In Canada, it is found from Quebec to Saskatchewan, plus an isolated population in Nova Scotia, where it grows on gypsum based soils, 330 km away from the nearest population in Maine.
Cypripedium passerinum is a species of lady's slipper orchid known by the common names sparrow's-egg lady's-slipper, spotted lady's-slipper, and Franklin's lady's-slipper.
Agalinis auriculata is a species of flowering plant in the family Orobanchaceae known as earleaf false foxglove, auriculate false foxglove, and earleaf gerardia. It is endemic to the United States, where it occurs from New Jersey west to Minnesota and throughout most southern states.
Neottia bifolia, common name southern twayblade, is a species of terrestrial orchid found in eastern Canada and the eastern United States.
Neottia borealis, the northern twayblade, is a species of terrestrial orchid found in North America. It is widespread across much of Canada, including the three Arctic territories, and also occurs in the mountains of the western United States from Alaska to northern New Mexico.
Neottia smallii, the kidneyleaf twayblade or Appalachian twayblade, is a species of terrestrial orchid found in the eastern United States. It occurs in the Appalachian Mountains from northern New Jersey to northeastern Georgia.
Liparis liliifolia, known as the brown widelip orchid, lily-leaved twayblade, large twayblade, and mauve sleekwort, is a species of orchid native to eastern Canada and the eastern United States. It can be found in a variety of habitats, such as forests, shrublands, thickets, woodlands, and mountains. The orchid is considered globally secure, but it is considered rare or endangered in many northeastern states.
