Monotropa
''Monotropa'' is a genus of three species of herbaceous perennial flowering plants that were formerly classified in the family Monotropaceae and presently are classified in Ericaceae. They are native to temperate regions of the Northern Hemisphere and are generally rare. Unlike most plants they do not have chlorophyll and therefore are non-photosynthetic; rather, they are myco-heterotrophs that obtain food through parasitism on subterranean fungi. Because they do not need any sunlight to live, they can live in very dark sites such as the floor of deep sylvae. The name "Monotropa" is Greek for "one turn" as every plant has one large turn near the top of the plant. Species The genus consists of the following three species: *'' Monotropa coccinea'' * ''Monotropa hypopitys'' * ''Monotropa uniflora'' '' Monotropa brittonii'' has been proposed as a separate species from ''Monotropa uniflora''. See also * ''Sarcodes ''Sarcodes'' is the monotypic genus of a north-west American f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monotropa Hypopitys
''Monotropa hypopitys'', the so-called Dutchman's pipe, false beech-drops, pinesap, or yellow bird's-nest, is a herbaceous perennial plant, formerly classified in the families Monotropaceae or Pyrolaceae, but now included within the subfamily Monotropoideae of the family Ericaceae. It is native to temperate regions of the Northern Hemisphere, and is scarce or rare in many areas. However, it is still the most widespread member of the subfamily. While currently included in the genus ''Monotropa'', recent genetic evidence strongly suggests that ''Monotropa hypopitys'' should be placed in its own genus, ''Hypopitys'', with the single species ''Hypopitys monotropa'' Crantz, but possibly containing several other species. Unlike most plants, it does not contain chlorophyll; it is a myco-heterotroph, getting its food through parasitism upon fungi rather than photosynthesis. These fungi form a mycorrhiza with nearby tree species. Plants are fleshy and grow 10–35 cm tall. True ste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monotropa Uniflora
''Monotropa uniflora'', also known as ghost plant, ghost pipe, or Indian pipe, is an herbaceous perennial plant native to temperate regions of Asia, North America, and northern South America, but with large gaps between areas. The plant is sometimes completely waxy white, but often has black flecks or pale pink coloration. Rare variants may have a deep red color. The name "Monotropa" is Greek for "one turn" and "uniflora" is Latin for "one flowered" as there is one sharply curved stem for each single flower. Description The stems reach heights of , sheathed with highly reduced leaves long, best identified as scales or bracts. These structures are small, thin, and translucent; they do not have petioles but instead extend in a sheath-like manner out of the stem. As its scientific name suggests, and unlike the related ''Monotropa hypopitys'' (but like the close relation '' Monotropastrum humile''), the stems bear a single flower long, with 3–8 translucent petals, 10–12 stamen ...

Monotropoideae
Monotropoideae, sometimes referred to as monotropes, are a flowering plant subfamily in the family Ericaceae. Members of this subfamily are notable for their mycoheterotrophic and non-photosynthesizing or achlorophyllous characteristics. Description The overall morphology of these plants is highly reduced compared to other members of the Ericaceae, which are practically all subshrubs, shrubs, or trees. By contrast, the Monotropoideae are all herbaceous perennials, in which an annual shoot reemerges seasonally (in spring or early summer, depending on climate) from a perennial root. The shoot can be characterized as a single inflorescence or cluster of inflorescences, and is generally a raceme with one to many flowers per axis, though occasionally the raceme may be so reduced as to appear similar to a spike, and in ''Monotropa'', the inflorescence can take the form of a solitary flower. Notably, the shoots are achlorophyllous, in keeping with the mycoheterotrophic and non-photosynth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Myco-heterotrophs
Myco-heterotrophy (from Greek μύκης , "fungus", ἕτερος ', "another", "different" and τροφή ', "nutrition") 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. Relationship between myco-heterotrophs and host fungi Full (or obligate) myco-heterotrophy exists when a non-photosynthetic plant (a plant largely lacking in chlorophyll or otherwise lacking a functional photosystem) gets all of its food from the fungi that it parasitizes. Partial (or facultative) myco-heter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ericaceae Genera
The Ericaceae are a family of flowering plants, commonly known as the heath or heather family, found most commonly in acidic and infertile growing conditions. The family is large, with c.4250 known species spread across 124 genera, making it the 14th most species-rich family of flowering plants. The many well known and economically important members of the Ericaceae include the cranberry, blueberry, huckleberry, rhododendron (including azaleas), and various common heaths and heathers (''Erica'', ''Cassiope'', ''Daboecia'', and ''Calluna'' for example). Description The Ericaceae contain a morphologically diverse range of taxa, including herbs, dwarf shrubs, shrubs, and trees. Their leaves are usually evergreen, alternate or whorled, simple and without stipules. Their flowers are hermaphrodite and show considerable variability. The petals are often fused (sympetalous) with shapes ranging from narrowly tubular to funnelform or widely urn-shaped. The corollas are usually radially ...

Sarcodes
''Sarcodes'' is the monotypic genus of a north-west American flowering springtime plant in the heath family (Ericaceae), containing the single species ''Sarcodes sanguinea'', commonly called the snow plant or snow flower. It is a parasitic plant that derives sustenance and nutrients from mycorrhizal fungi that attach to tree roots. Lacking chlorophyll, it is unable to photosynthesize. Ectomycorrhizal (EM) symbioses involve a mutualism between a plant root and a fungus; the plant provides fixed carbon to the fungus and in return, the fungus provides mineral nutrients, water, and protection from pathogens to the plant. The snow plant takes advantage of this mutualism by tapping into the network and stealing sugars from the photosynthetic partner by way of the fungus. This is known as mycoheterotrophy. The snow plant is host-specific and can only form relationships with the ectomycorrhizal Basidiomycete '' Rhizopogon ellenae.'' The plant's aboveground tissue is its inflorescence ...

Forest
A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, '' Global Forest Resources Assessment 2020'' (FRA 2020) found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the predominant terrestrial ecosystem of Earth, and are found around the globe. More than half of the world's forests are found in only five countries (Brazil, Canada, China, Russia, and the United States). The largest share of forests (45 percent) are in th ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
