Corallorhiza odontorhiza, common name fall coral-root or small-flowered coral-root, is a species of orchid widespread across eastern and central United States, and reported also from Mexico, Central America, Quebec and Ontario. In North America, it occurs in forested areas up to an elevation of 2800 m (9300 feet). [1] [5] [6] [7]
Corallorhiza odontorhiza is a non-photosynthetic species, with no chlorophyll. Hence it relies on fungi in the soil to supply it with nutrients. Stems are yellow to brown, bulbous at the base. There are no leaves. Flowers are typically reddish-purple with a white lip, the lip with small purple spots, though some plants are cleistogamous with non-opening flowers. [8] The plant flowers from August through October in the eastern US. [9] [10] [11]
Three infraspecific taxa are recognized as of May 2014: [1]
The flowers of var. odontorhiza are cleistogamous and either closed or only slightly open. Often one or two flowers in a raceme will be open slightly more than the others and a narrow lip (2.6-3.8mm long, 1.7-2.2mm wide) may be visible. Because flowers self-pollinate and no external pollinators are required first, the ovaries of this variation will start swelling soon after flowering. [9]
Flowers of var. pringlei are chasmogamous and will open up. Their upper two petals and upper sepal form a hood, with the two side sepals bending outwards. The lip is visible and wider than with var. odonthoriza - it is used by pollinators to land on. [12]
This form of var. pringlei is only known from southern Mexico, Guatemala and El Salvador. It is completely cleistogamous and peloric - that is unlike with var. odontorhiza the bottom-most petal does not form a lip but looks just like the other 5 petals/sepals. Since it is assumed that a peloric form of the orchid could develop anywhere as a spontaneous mutation it is only recognized as a form and not a full variation. [9]
Cypripedium is a genus of 58 species and nothospecies of hardy orchids; it is one of five genera that together compose the subfamily of lady's slipper orchids (Cypripedioideae). They are widespread across much of the Northern Hemisphere, including most of Europe and Africa (Algeria), Russia, China, Central Asia, Canada the United States, Mexico, and Central America. They are most commonly known as slipper orchids, lady's slipper orchids, or ladyslippers; other common names include moccasin flower, camel's foot, squirrel foot, steeple cap, Venus' shoes, and whippoorwill shoe. An abbreviation used in trade journals is "Cyp." The genus name is derived from Ancient Greek Κύπρις (Kúpris), an early reference in Greek myth to Aphrodite, and πέδιλον (pédilon), meaning "sandal".
Calypso is a genus of orchids containing one species, Calypso bulbosa, known as the calypso orchid, fairy slipper or Venus's slipper. It is a perennial member of the orchid family found in undisturbed northern and montane forests. It has a small pink, purple, pinkish-purple, or red flower accented with a white lip, darker purple spottings, and yellow beard. The genus Calypso takes its name from the Greek signifying concealment, as they tend to favor sheltered areas on conifer forest floors. The specific epithet, bulbosa, refers to the bulb-like corms.
Corallorhiza maculata, or spotted coralroot, is a North American coralroot orchid. It has four varieties: C. maculata var. occidentalis, C. maculata var. maculata, C. maculata var. mexicana, and C. maculata var. ozettensis. It is widespread through Mexico, Guatemala, Canada, St. Pierre & Miquelon, and much of the western and northern United States. It grows mostly in montane woodlands.
Corallorhiza trifida, commonly known as early coralroot, northern coralroot, or yellow coralroot, is a coralroot orchid native to North America and Eurasia, with a circumboreal distribution. The species has been reported from the United States, Canada, Russia, China, Japan, Korea, India, Nepal, Kashmir, Pakistan, and almost every country in Europe.
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.
Lycaste, abbreviated as Lyc. in horticultural trade, is a genus of orchids that contains about 30 species with egg-shaped pseudobulbs and thin, plicate (pleated) leaves.
Restrepiella ophiocephala, commonly called the Snake's head restrepiella is an epiphytic orchid native to Mexico, Central America, Colombia, and Florida. The epithet ophiocephala is derived from the Greek words ὄφις, ophis (snake) and κεφαλή, kephalē (head).
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. In america they are found from eastern Oklahoma north to eastern South Dakota in the west and from Atlanta, Georgia and North Alabama north up into Maine to the east.
Cyrtostylis, commonly known as gnat orchids, is a genus of five or six species of flowering plants in the orchid family Orchidaceae and is native to Australia and New Zealand. Cyrtostylis orchids often form dense colonies of genetically identical plants. They have a single heart-shaped leaf and a thin flowering stem with pale coloured insect-like flowers. The lateral sepals and petals are similar in size and colour but the labellum is shelf-like and conspicuous with two prominent glands at its base.
Corallorhiza striata is a species of orchid known by the common names striped coralroot and hooded coralroot. This flowering plant is widespread across much of southern Canada, the northern and western United States, and Mexico. It lives in dry, decaying plant matter on the ground in pine and mixed coniferous forests, and it obtains its nutrients from fungi via mycoheterotrophy.
Corallorhiza mertensiana, or Pacific coralroot, is a coralroot orchid native to the shady conifer forests of northwestern North America. It also goes by the common names Western coralroot and Mertens' coralroot. Corallorhiza mertensiana was previously considered a subspecies of Corallorhiza maculata but was given species rank in 1997 by Freudenstein.

Orchids in this genus as well as the hammer orchids (Drakaea) are pollinated by male thynnid wasps.
