Cupressus arizonica, the Arizona cypress, is a North American species of tree in the cypress family Cupressaceae, native to the southwestern United States and Mexico. Populations may be scattered rather than in large, dense stands.
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.
Corallorhiza maculata, or spotted coralroot, is a North American coralroot orchid. It has three varieties: C. maculata var. occidentalis, C. maculata var. maculata, and C. maculata var. mexicana. 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, the coralroot, is a genus of flowering plants in the orchid family. Except for the circumboreal C. trifida, the genus is restricted to North America.
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.
Calopogon tuberosus, the tuberous grass pink, is an orchid native to eastern North America.
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, Greenland, Pakistan, and almost every country in Europe.
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.
Malaxis unifolia, or the green adder's-mouth orchid, is a species of orchid occurring from eastern and central Canada, the central and eastern United States, Mexico, Central America and the Greater Antilles.
Arbutus arizonica, commonly known as Arizona madrone, is a tree species in the heath family that is native to the southwestern United States and northwestern Mexico. Its range extends along the Sierra Madre Occidental cordillera from the Madrean Sky Islands of southeastern Arizona and southwestern New Mexico south as far as Jalisco. It has been found in Sonora, Chihuahua, Durango, and Sinaloa, with one isolated population in Tamaulipas.
Lynx Prairie is a 52-acre (210,000 m2) nature preserve located in Adams County, Ohio, United States, near the community of Lynx. The preserve features a group of cedar glades which harbor rare prairie species, surrounded by forests on all sides.
Orthochilus ecristatus, or giant orchid, is a terrestrial species of orchid native to Cuba and to the southeastern United States. It was previously known as Eulophia ecristata or Pteroglossaspis ecristata until recently transferred to the genus Orthochilus. This is one of several species known as a "giant orchid".
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 grandiflora, the largeflower crested coralroot or giant coral-root, is a species of orchid native to Mexico from Chihuahua south to Oaxaca, as well as to western and north-central Texas. It is a myco-heterotrophic species, lacking chlorophyll and subsisting entirely on nutrients obtained by fungi in the soil.
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.
Spiked crested coralroot is a common name for two plants which are sometimes considered to belong to the same species:
Gaillardia arizonica, the Arizonia blanketflower, is a species of flowering plant in the sunflower family. It is native to northwestern Mexico (Sonora) and the southwestern United States.
Grindelia arizonica, the Arizona gumweed, is a North American species of flowering plants in the daisy family. It is native to the southwestern United States and northern Mexico, in the States of Coahuila, Chihuahua, Arizona, New Mexico, Utah, Texas, and Colorado.
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.
