Dichanthelium Oligosanthes
''Dichanthelium oligosanthes'', known as Heller's rosette grass, fewanther obscuregrass, and few-flowered panicgrass, is a frost-tolerant, perennial grass species native to North America. It is found primarily in the contiguous United States with specimens also reported in British Columbia and Alberta in Canada, as well as south of the Rio Grande in northern Mexico. ''D. oligosanthes'' is most frequently in partially shaded glens within woods, recently cut forests, and grassy banks. The species is primarily cleistogamous, with individual florets often self pollinate without opening. Despite being a member of the grass subfamily Panicoideae which includes many species which utilize C4 photosynthesis, ''D. oligosanthes'' retains the more ancestral trait, using a C3 photosynthetic pathway. The genome of ''Dichanthelium oligosanthes'' is carried on nine chromosomes and is estimated to be between 750 and 950 megabases in size. A draft genome assembly was generated from the progeny ...

British Columbia
British Columbia (commonly abbreviated as BC) is the westernmost province of Canada, situated between the Pacific Ocean and the Rocky Mountains. It has a diverse geography, with rugged landscapes that include rocky coastlines, sandy beaches, forests, lakes, mountains, inland deserts and grassy plains, and borders the province of Alberta to the east and the Yukon and Northwest Territories to the north. With an estimated population of 5.3million as of 2022, it is Canada's third-most populous province. The capital of British Columbia is Victoria and its largest city is Vancouver. Vancouver is the third-largest metropolitan area in Canada; the 2021 census recorded 2.6million people in Metro Vancouver. The first known human inhabitants of the area settled in British Columbia at least 10,000 years ago. Such groups include the Coast Salish, Tsilhqotʼin, and Haida peoples, among many others. One of the earliest British settlements in the area was Fort Victoria, established ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alberta
Alberta ( ) is one of the thirteen provinces and territories of Canada. It is part of Western Canada and is one of the three prairie provinces. Alberta is bordered by British Columbia to the west, Saskatchewan to the east, the Northwest Territories (NWT) to the north, and the U.S. state of Montana to the south. It is one of the only two landlocked provinces in Canada (Saskatchewan being the other). The eastern part of the province is occupied by the Great Plains, while the western part borders the Rocky Mountains. The province has a predominantly continental climate but experiences quick temperature changes due to air aridity. Seasonal temperature swings are less pronounced in western Alberta due to occasional Chinook winds. Alberta is the fourth largest province by area at , and the fourth most populous, being home to 4,262,635 people. Alberta's capital is Edmonton, while Calgary is its largest city. The two are Alberta's largest census metropolitan areas. More tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rio Grande
The Rio Grande ( and ), known in Mexico as the Río Bravo del Norte or simply the Río Bravo, is one of the principal rivers (along with the Colorado River) in the southwestern United States and in northern Mexico. The length of the Rio Grande is . It originates in south-central Colorado, in the United States, and flows to the Gulf of Mexico. The Rio Grande drainage basin (watershed) has an area of ; however, the endorheic basins that are adjacent to and within the greater drainage basin of the Rio Grande increase the total drainage-basin area to . The Rio Grande with Rio Grande Valley (landform), its fertile valley, along with its tributaries, is a vital watersource for seven US and Mexican states, and flows primarily through arid and semi-arid lands. After traversing the length of New Mexico, the Rio Grande becomes the Mexico–United States border, between the U.S. state of Texas and the northern Mexican states of Chihuahua (state), Chihuahua and Coahuila, Nuevo León a ...

Glen
A glen is a valley, typically one that is long and bounded by gently sloped concave sides, unlike a ravine, which is deep and bounded by steep slopes. Whittow defines it as a "Scottish term for a deep valley in the Highlands" that is "narrower than a strath".. The word is Goidelic in origin: ''gleann'' in Irish and Scottish Gaelic, ''glion'' in Manx. The designation "glen" also occurs often in place names. Etymology The word is Goidelic in origin: ''gleann'' in Irish and Scottish Gaelic, ''glion'' in Manx. In Manx, ''glan'' is also to be found meaning glen. It is cognate with Welsh ''glyn''. Examples in Northern England, such as Glenridding, Westmorland, or Glendue, near Haltwhistle, Northumberland, are thought to derive from the aforementioned Cumbric cognate, or another Brythonic equivalent. This likely underlies some examples in Southern Scotland. As the name of a river, it is thought to derive from the Irish word ''glan'' meaning clean, or the Welsh word ''gleindid' ...

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. However, the largest genus of cleistogamous plants is ''Viola''. The more common opposite of cleistogamy, or "closed marriage", is called chasmogamy, or "open marriage". Virtually all plants that produce cleistogamous flowers also produce chasmogamous ones.Meeuse, Bastiaan and Sean Morris. 1984. The sex life of flowers. New York, NY: Facts on File Publishers. pp 110-111. The principal advantage of cleistogamy is that it requires fewer plant resources to produce seeds than does chasmogamy, because development of petals, nectar and large amounts of pollen is not required. This efficiency makes cleistogamy particularly useful for seed production on unfavorable sites or adverse conditions. ''Impatiens capensis,'' for example, has been o ...

C4 Photosynthesis
carbon fixation or the Hatch–Slack pathway is one of three known photosynthetic processes of carbon fixation in plants. It owes the names to the 1960's discovery by Marshall Davidson Hatch and Charles Roger Slack that some plants, when supplied with 14, incorporate the 14C label into four-carbon molecules first. fixation is an addition to the ancestral and more common carbon fixation. The main carboxylating enzyme in photosynthesis is called RuBisCO, which catalyses two distinct reactions using either (carboxylation) or oxygen (oxygenation) as a substrate. The latter process, oxygenation, gives rise to the wasteful process of photorespiration. photosynthesis reduces photorespiration by concentrating around RuBisCO. To ensure that RuBisCO works in an environment where there is a lot of carbon dioxide and very little oxygen, leaves generally differentiate two partially isolated compartments called mesophyll cells and bundle-sheath cells. is initially fixed in the ...

Shaw Nature Reserve
Shaw Nature Reserve, formerly known as Shaw Arboretum, is a private non-profit nature reserve located in Gray Summit, Missouri, that is operated as an extension of the Missouri Botanical Garden. The first piece of land, , was purchased in 1925 when pollution from coal smoke in St. Louis threatened the Garden's live plant collection, especially the orchid collection. The orchids were moved to what was then known as the Gray Summit Extension in 1926. The pollution in St. Louis decreased with the waning use of coal for heat, making it unnecessary to move the rest of the live plant collection. The Garden made five more land purchases between 1926-1977 amounting to the Nature Reserve's current size of . Shaw Nature Reserve has several historic homes (including the Joseph H. Bascom House), a large tallgrass prairie, and a wetland blind from which herons can be observed. The Nature Reserve is also home to the Whitmire Wildflower Garden, a Missouri native garden with over 500 nativ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dichanthelium
''Dichanthelium'' is genus of flowering plants of the grass family, Poaceae. They are known commonly as rosette grasses and panicgrasses.''Dichanthelium''. USDA PLANTS. Taxonomy Formerly a subgenus of the genus '''', ''Dichanthelium'' was elevated to genus status in 1974. Its species are still treated as members of ''Panicum'' by some authorities, because the two genera are very similar in form.
