Platanthera chorisiana, Chamisso's orchid or Choris' bog orchid, [1] is a terrestrial orchid native to the United States, Canada, Russia and Japan. [2]
Platanthera chorisiana plants are small, from 4 up to 20 cm. They usually have two leaves at the base of the stem (sometimes just one or up to four). The small flowers (petals are only 1.5-2.5 mm) have a greenish color and are often not fully turned (resupinate). There is a very short nectar spur. Bloom time is July and August. [3] [1]
Sometimes two subspecies are considered, Platanthera chorisiana var. chorisiana and Platanthera chorisiana var. elata. The latter subspecies only grows in Asia. [4]
In the United States Platanthera chorisiana is found in Washington (state) and Alaska, in Canada in British Columbia. Worldwide distribution is around the northern pacific coast, extending west along the Aleutian Islands to Kamchatka in Russia and to northern Japan.
Plants grow in bogs and wet tundra up to a maximum elevation of 400 m. [3]
Platanthera chorisiana was first described by Adelbert von Chamisso in 1828 as Habenaria chorisiana. [5]
Hepatica is a genus of herbaceous perennials in the buttercup family, native to central and northern Europe, Asia and eastern North America. Some botanists include Hepatica within a wider interpretation of Anemone.
Neotinea ustulata, the burnt orchid or burnt-tip orchid, is a European terrestrial orchid native to mountains in central and southern Europe, growing at up to 2,400 m (7,900 ft) elevation. The plant is considered Endangered in Great Britain and Least Concern internationally based on IUCN Red List criteria. The burnt-tip orchid was voted the county flower of Wiltshire in 2002 following a poll by the wild flora conservation charity Plantlife.
Habenaria, commonly called rein orchids or bog orchids, is a widely distributed genus of orchids in the tribe Orchideae. About 880 species of Habenaria have been formally described. They are native to every continent except Antarctica, growing in both tropical and subtropical zones.
The genus Platanthera belongs to the subfamily Orchidoideae of the family Orchidaceae, and comprises about 150 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.
Anemone hepatica, the common hepatica, liverwort, kidneywort, or pennywort, is a species of flowering plant in the buttercup family Ranunculaceae, native to woodland in temperate regions of the Northern Hemisphere. This herbaceous perennial grows from a rhizome.
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.
Malaxis monophyllos, the white adder's mouth, is a terrestrial species of orchid. It is widespread across much of Europe, Asia, and much of southern Canada. In the United States, it grows mostly in southern Alaska, New England and the Great Lakes region, with isolated populations reported from Colorado and California.
Platanthera hyperborea, the northern green orchid, is small orchid found only in Greenland, Iceland, and Akimiski Island in Canada. Numerous authors cite the species as widespread in other parts of Canada and also in the United States; such populations are more correctly referred to as Platanthera aquilonis.
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 orbiculata, the round leaved orchid or lesser roundleaved orchid, is a species of orchid native to forested areas of North America. It is widespread across most of Canada and parts of the United States.
Habenaria repens, commonly called the water-spider bog orchid or the floating orchid, is an orchid species widespread across Latin America from Mexico and the West Indies south to Argentina, as well as in the Southeastern United States from Texas and Oklahoma east to Florida and the Carolinas plus an isolated population in Virginia.
Habenaria macroceratitis, the big-horn bog orchid or long-horned false rein orchid, is a species of orchid closely related to H. quinqueseta and often mistaken for it. Habenaria macroceratitis is native to Central America, Mexico, the West Indies, northern South America, and Florida.
Platanthera zothecina is a perennial plant in the orchid family (Orchidaceae) found in the Colorado Plateau and Canyonlands region of the southwestern United States and is found in the states of Utah, Arizona and Colorado.
Habenaria rumphii, commonly known as the stiff rein orchid, is a species of orchid that is widespread and common in Southeast Asia, New Guinea and northern Australia. It has six or seven leaves on the lower part of its stem and up to thirty white flowers with one long and two short lobes on the labellum.
Platanthera dilatata, known as tall white bog orchid, bog candle, or boreal bog orchid is a species of orchid, a flowering plant in the family Orchidaceae, native to North America. It was first formally described in 1813 by Frederick Traugott Pursh as Orchis dilatata.
Platanthera brevifolia, the shortflowered bog orchid or short-leaf bog orchid, is a terrestrial orchid of North America.
Platanthera convallariifolia, the bog orchid, is a species of orchid native to the Aleutian Islands, far east Russia and northern Japan. It grows in wetlands such as fens and marshes.
Coenoemersa limosa, commonly known as Thurber's bog orchid, is a terrestrial orchid of Guatemala, Mexico and the United States.
Platanthera tipuloides, the Aleutian Bog Orchid or Bering Bog Orchid, is a terrestrial orchid native to the United States, Russia, China, Japan and Korea.
Spiranthes praecox, the Grass Leaved Ladies' Tresses, Green-vein Ladies'-tresses or sometimes Giant Ladies' Tresses is a terrestrial orchid endemic to the United States, growing on the eastern coastal plains and around the Gulf Coast.
