Ophrys apifera, known in Europe as the bee orchid, is a perennial herbaceous plant of the family Orchidaceae. It serves as an example of sexually deceptive pollination and floral mimicry, as well as of a highly selective and highly evolved plant–pollinator relationship.
Stanhopea is a genus of the orchid family (Orchidaceae) from Central and South America. The abbreviation used in horticultural trade is Stan. The genus is named for the 4th Earl of Stanhope (1781-1855), president of the Medico-Botanical Society of London (1829-1837). It comprises 55 species and 5 natural hybrids. These epiphytic, but occasionally terrestrial orchids can be found in damp forests from Mexico to Trinidad to NW Argentina. Their ovate pseudobulbs carry from the top one long, plicate, elliptic leaf.
Platanthera praeclara, known as the western prairie fringed orchid and the Great Plains white fringed orchid, is a rare and threatened species of orchid native to North America.
Platanthera leucophaea, commonly known as the prairie white fringed orchid or eastern prairie fringed orchid, is a rare species of orchid native to North America. It is listed as a threatened species in the United States on September 28, 1989. The IUCN does not currently recognize it as being at risk.
Caladenia, commonly known as spider orchids, is a genus of 350 species of plants in the orchid family, Orchidaceae. Spider orchids are terrestrial herbs with a single hairy leaf and a hairy stem. The labellum is fringed or toothed in most species and there are small projections called calli on the labellum. The flowers have adaptations to attract particular species of insects for pollination. The genus is divided into three groups on the basis of flower shape, broadly, spider orchids, zebra orchids and cowslip orchids, although other common names are often used. Although they occur in other countries, most are Australian and 136 species occur in Western Australia, making it the most species-rich orchid genus in that state.
Coeloglossum is a genus of flowering plants in the orchid family Orchidaceae. It has long been considered to have only one species, Coeloglossum viride, the frog orchid. Some recent classifications regard Coeloglossum as part of the larger genus, Dactylorhiza, so that C. viride becomes Dactylorhiza viridis. Other sources continue to keep Coeloglossum viride separate.
The genus Platanthera belongs to the subfamily Orchidoideae of the family Orchidaceae, and comprises about 100 species of orchids. The members of this genus, known as the butterfly orchids or fringed orchids, were previously included in the genus Orchis, which is a close relative. They are distributed throughout the temperate regions of the Northern Hemisphere. They are terrestrial and have tubercules.
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.
Scaphyglottis is a genus of orchids native to Mexico, Central America, northern South America and parts of the Caribbean. The current concept of this genus is the result of combining several genera which have been described at various times. The concept is characterized by the growth habit: not only are new pseudobulbs added at the base of the old ones, but new pseudobulbs also grow at the apices of the old ones. Many species are quite similar and difficult to distinguish, but some are clearly distinct. A few have showy colors. The genus comprises nearly 70 species.
Platanthera grandiflora, the greater purple fringed orchid, is a species of orchid, genus Platanthera, occurring from Ontario to Newfoundland, south along the Appalachian Mountains to northeastern Georgia, with an isolated population in Illinois. It is imperiled in Georgia, Tennessee, Virginia and North Carolina.
Serapias vomeracea, common name long-lipped serapias or the plow-share serapias, is a species of orchid in the genus Serapias.
Calochilus, commonly known as beard orchids, is a genus of about 30 species of plants in the orchid family, Orchidaceae. Beard orchids are terrestrial herbs with a single leaf at the base of the plant, or no leaves. Their most striking feature is a densely hairy labellum, giving rise to their common name. Beard orchids, unlike some other Australian orchids, do not reproduce using daughter tubers, but self-pollinate when cross-pollination has not occurred. Most species occur in Australia but some are found in New Zealand, New Guinea and New Caledonia.
Caleana, commonly known as duck orchids, is a genus of flowering plants in the orchid family, Orchidaceae that is found in Australia and New Zealand. The Australian species are found in all states but have not been recorded in the Northern Territory. Duck orchids have a single leaf and one or a few, dull-coloured, inconspicuous flowers. Most species are found in Western Australia but one species occurs in eastern Australia and one occurs in eastern Australia and New Zealand. Orchids in this genus as well as the hammer orchids (Drakaea) are pollinated by male thynnid wasps.
Platanthera obtusata, common name blunt-leaved orchid or small northern bog orchid, is a small species of orchid in the genus Platanthera. It widespread across much of the colder regions of the Northern Hemisphere, though rare in some parts of its range. Two subspecies are recognized:
Platanthera peramoena, the purple fringeless orchid, is a species of flowering plant in the orchid family. It is native to the Eastern United States, where it is found from the Mid-Atlantic states, the Ohio Valley and the Ozark Mountains. Its natural habitat is moist forests, marshes, and on streambanks.
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.
Drakaea concolor, commonly known as the kneeling hammer orchid, is a species of orchid endemic to the south–west of Western Australia. The species is only known from a few areas in the far west of the state and has been declared "vulnerable" by the Australian Government and "threatened" by the Government of Western Australia.
Drakaea elastica, commonly known as glossy-leaved hammer orchid or praying virgin is a species of orchid endemic to the south–west of Western Australia. It is similar to other hammer orchids in that it is pollinated by a single species of male thynnid wasp using sexual deception. The orchid's labellum is similar in shape and scent to a flightless female thynnid wasp. The glossy-leaved hammer orchid was the first in the genus to be described. The species is only known from the far south-west of the state and has been declared "endangered" by both the Australian government and the government of Western Australia.
Drakaea micrantha, commonly known as the dwarf hammer orchid is a species of orchid endemic to the south–west of Western Australia. It is similar to other hammer orchids in that it is pollinated by a single species of male thynnid wasp using sexual deception. The orchid's labellum is similar in shape and scent to a flightless female thynnid wasp. It has a single silvery-grey, heart-shaped leaf with prominent green veins and a stem up to 30 centimetres (12 in) long. The species is only known from a scattered populations in the south west of the state and has been declared "vulnerable" by the Australian government and "threatened" by the government of Western Australia.
Platanthera hookeri, otherwise known as Hooker's orchid or Hooker's bog orchid, is a perennial wildflower in the genus Platanthera that can be found in temperate regions of North America ranging from Iowa to Newfoundland.
