Coreopsis is a genus of flowering plants in the family Asteraceae. Common names include calliopsis and tickseed, a name shared with various other plants.
Burmanniaceae is a family of flowering plants, consisting of 99 species of herbaceous plants in eight genera.
Hexalectris is a genus of the family Orchidaceae, comprising 10 known species of fully myco-heterotrophic orchids. These species are found in North America, with the center of diversity in northern Mexico. None of the species are particularly common. Hexalectris spicata has a wide distribution and is likely the most abundant member of the genus, but is nevertheless infrequent throughout its range. Other species are rare, and some, such as H. colemanii, are threatened or endangered. All species that have been studied form associations with ectomycorrhizal fungi that are likely linked to surrounding trees. Many Hexalectris species are found in association with oak trees (Quercus), which are ectomycorrhizal.
Galeola is a genus of orchids belonging to the subfamily Vanilloideae.
Coralroot is a common name for several plants which may refer to:
Myco-heterotrophy is a symbiotic relationship between certain kinds of plants and fungi, in which the plant gets all or part of its food from parasitism upon fungi rather than from photosynthesis. A myco-heterotroph is the parasitic plant partner in this relationship. Myco-heterotrophy is considered a kind of cheating relationship and myco-heterotrophs are sometimes informally referred to as "mycorrhizal cheaters". This relationship is sometimes referred to as mycotrophy, though this term is also used for plants that engage in mutualistic mycorrhizal relationships.
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.
Wullschlaegelia is a genus of orchids,, consisting of two species in the Caribbean Islands and to much of Latin America from southern Mexico to northern Argentina. These are myco-heterotrophic plants, lacking chlorophyll and subsisting entirely on nutrients obtained from soil fungi. The genus has previously been included in the tribe Calypsoeae, but is now included as the only genus in the tribe Wullschlaegelieae, pending further study.
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.
Platanthera psycodes, commonly called lesser purple fringed orchid or small purple-fringed orchid, is a species of orchid, genus Platanthera, occurring from eastern Canada to the east-central and northeastern United States. It is imperiled in Illinois, Tennessee, North Carolina, and Kentucky.
Uleiorchis is a genus of myco-heterotrophic flowering plants from the orchid family, Orchidaceae. There are two known species, native to Central and South America.
Corsia is a little-studied plant genus from the monocotyledon family Corsiaceae. It was first described in 1877 by Italian naturalist Odoardo Beccari and contains 25 species, all of which lack chlorophyll and parasitize fungi for nutrition. All 25 species are distributed through New Guinea, the Bismarck Archipelago, the Solomon Islands and Queensland, Australia.
Limodorum is a genus of myco-heterotrophic orchids. All species are temperate terrestrial plants and occur across much of Europe, North-West Africa, the Mediterranean Islands, and as far east as Iran. Plants have evolved away from photosynthesis and as a result their leaves are reduced to scales. There is still chlorophyll present but the plants are believed to be solely dependent on their fungal partner for nutrients. They spend most of their life underground as a short stem with fleshy roots, the unbranched inflorescence can appear in April to June if conditions are favourable.
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.
Hexalectris arizonica, the spiked crested coralroot or Arizona crested coralroot, is a terrestrial, myco-heterotrophic orchid lacking chlorophyll and subsisting entirely on nutrients obtained from mycorrhizal fungi in the soil. It is native to Arizona, New Mexico, Texas and Coahuila. It is closely related to H. spicata and sometimes regarded as a variety of that species.
Hexalectris spicata, the spiked crested coralroot, is a terrestrial, myco-heterotrophic orchid lacking chlorophyll and subsisting entirely on nutrients obtained from mycorrhizal fungi in the soil. It is native to Arizona, New Mexico, Texas and Coahuila. It is closely related to H. arizonica and the two are sometimes considered varieties of the same species. Hexalectris spicata is endemic to the southern half of the United States from Arizona east to Florida and north to Maryland and the Ohio Valley.
Hexalectris colemanii, or Coleman's crested coralroot, is a terrestrial, myco-heterotrophic orchid lacking chlorophyll and subsisting entirely on nutrients obtained from mycorrhizal fungi in the soil. It is a very rare species endemic to southern Arizona, known from only three counties. It is closely related to H. revoluta and the two are sometimes considered varieties of the same species.
Hexalectris revoluta, the Chisos Mountain crested coralroot, is a terrestrial, myco-heterotrophic orchid lacking chlorophyll and subsisting entirely on nutrients obtained from mycorrhizal fungi in the soil. It is closely related to H. colemanii; the two are regarded by some authors as varieties of the same species. Hexalectris revoluta is native to western Texas, southeastern New Mexico and Chihuahua.
Hexalectris warnockii, the Texas crested coralroot, Texas purple-spike, is a myco-heterotrophic orchid found in the states of Texas and Arizona in the southwestern United States, and in the states of Coahuila and Baja California Sur in northern Mexico. Being myco-heterotrophic, H. warnockii derives all of its nutrients from mycorrhizal fungi.
