Corallorhiza Bulbosa
''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 (including Mexico, Central America and the West Indies). Most species are putatively parasitic, relying entirely upon mycorrhizal fungi within their coral-shaped rhizomes for sustenance. Because of this dependence on myco-heterotrophy, they have never been successfully cultivated. Most species are leafless and rootless. Most species produce little or no chlorophyll, and do not utilize photosynthesis. An exception is the yellowish green species ''Corallorhiza trifida'', which has some chlorophyll and is able to fix CO2. However, this species also depends primarily on fungal associations for carbon acquisition. List of species Many species names have been proposed that are now considered synonyms of other species, or members of other genera.

Corallorhiza Trifida
''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.Gleason, H. A. & A.J. Cronquist. 1991. Manual of the Vascular Plants of Northeastern United States and Adjacent Canada (ed. 2) i–910. New York Botanical Garden, Bronx. Description ''Corallorhiza trifida'' is yellowish green in color, leafless, and partially myco-heterotrophic, deriving some, but not all of its nutrients from association with fungi of genus ''Tomentella''.Zimmer, K., et al. (2008)The ectomycorrhizal specialist orchid ''Corallorhiza trifida'' is a partial myco-heterotroph.''New Phytologist'' 178:2 395-400. It also contains chlorophyll, with which it supplies some of its own carbon nutrition via autotrophy ...

Corallorhiza Bentleyi
''Corallorhiza bentleyi'' is a rare species of orchid known deciduous forests in the mountains of Virginia and West Virginia. It was undescribed until 1999. It is a parasitic plant, with yellow to reddish stems and cleistogamous Cleistogamy is a type of automatic self-pollination of certain plants that can propagate by using non-opening, self-pollinating flowers. Especially well known in peanuts, peas, and pansies, this behavior is most widespread in the grass family. How ... flowers.

Corallorhiza Striata
''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. Description Like other coralroot orchids, the plant takes its name from its coral-shaped rhizomes. It has an erect stem about tall that may be red, pink, purple, or yellow-green to almost white. The leaves lack chlorophyll and are reduced to colourless scales that sheath the stem. The plant also lacks roots, and relies upon parasitism of fungi for sustenance. The stem is topped by a raceme of 15 to 25 orchid flowers. Each flower is an open array of sepal A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the ...

Badlands Flowers - Corallorhiza Striata (6ddc1050-1a8e-45c8-bce7-5ccd66e8b803)
Badlands are a type of dry terrain where softer sedimentary rocks and clay-rich soils have been extensively eroded."Badlands" in ''Chambers's Encyclopædia''. London: George Newnes, 1961, Vol. 2, p. 47. They are characterized by steep slopes, minimal vegetation, lack of a substantial regolith, and high drainage density.A.J. Parsons and A.D. Abrahams, Editors (2009) ''Geomorphology of Desert Environments'' (2nd ed.) Springer Science & Business Media Ravines, gullies, buttes, hoodoos and other such geologic forms are common in badlands. Badlands are found on every continent except Antarctica, being most common where there are unconsolidated sediments. They are often difficult to navigate by foot, and are unsuitable for agriculture. Most are a result of natural processes, but destruction of vegetation by overgrazing or pollution can produce anthropogenic badlands. Badlands topography Badlands are characterized by a distinctive badlands topography. This is terrain in which wate ...

Corallorhiza Odontorhiza
''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). ''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. The plant flowers from August through October in the eastern US.Freudenstein, J. V. 1997. A monograph of ''Corallorhiza'' (Orchidaceae). Harvard Papers in Botany 1(10): 5–51.Hamer, F. 1988.

Corallorhiza Mertensiana
''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.Turner, Mark & Phyllis Gustafson. Wildflowers of the Pacific Northwest. Timber Press Field Guide.

Description ''Corallorrhiza mertensiana'' is a leafless, parasitic, perennial orchid that is 6-20 inches tall. The stem is red to brownish purple. The upper petals are pink to reddish pink, with yellow to dark red veins. The lower petals are wider, dark pink to red, and have three deep red veins. Beneath the lower petal the spur is prominent. The flower spikes are visible from May to August. ''Corallorrhiza mertensiana'' has no roots, only hard, branched rhizomes that resemble coral. Fungal associations ''Corallorrhiza m ...

Corallorhiza Maculata
''Corallorhiza maculata'', or spotted coralroot, is a North American coralroot orchid. It has three varieties: ''C. maculata var. occidentalis'' (western spotted coralroot), ''C. maculata var. maculata'' (eastern spotted coralroot or summer coralroot), and ''C. maculata var. mexicana''. It is widespread through Mexico, Guatemala, Canada, St. Pierre & Miquelon, and much of the western and northern United States (though generally absent from the Great Plains and from the lowland parts of the Southeast). It grows mostly in montane woodlands. Description ''Corallorhiza maculata'' is a myco-heterotroph; it lacks chlorophyll and obtains energy by parasitizing the mycelium of fungi in the family Russulaceae. The rhizome and lower stem are often knotted into branched coral shapes. The stem is usually red or brown in color, but occasionally comes in a light yellow or cream color. There are no leaves and no photosynthetic green tissues. The stems bear dark red scales and intricate orc ...
