Symphyotrichum Nahanniense
''Symphyotrichum nahanniense'' (formerly ''Aster nahanniensis'') is a species of flowering plant in the family Asteraceae endemic to Northwest Territories, Canada. Description Commonly known as Nahanni aster, it is a perennial, herbaceous plant that grows about in height. Its flowers have white to pale rose, often becoming rose-violet, ray florets and yellow then reddish disk florets. Distribution and habitat The species grows only within Nahanni National Park Reserve and has been found at seven hot mineral spring Mineral springs are naturally occurring springs that produces hard water, water that contains dissolved minerals. Salts, sulfur compounds, and gases are among the substances that can be dissolved in the spring water during its passage underg ...s locations within the Park. A survey conducted in 2019 recorded about 130,000 plants. Gallery Symphyotrichum nahanniense 31585717.jpg Symphyotrichum nahanniense 31585674 (cropped).jpg Citations Referen ...

Nahanni National Park Reserve
Nahanni National Park Reserve in the Dehcho Region of the Northwest Territories, Canada, approximately west of Yellowknife, protects a portion of the Mackenzie Mountains Natural Region. The centrepiece of the park is the South Nahanni River (''Naha Dehé''). Four noteworthy canyons reaching in depth,Parks Canada. 2007. South Nahanni River Touring Guide. called First, Second, Third and Fourth Canyon, line its whitewater river. The name Nahanni comes from the indigenous Dene language name for the area; Nahʔa Dehé, which means "river of the land of the Nahʔa people".Parks Canada. 2002. Nahanni National Park Reserve Natural and Cultural Guide to Nahʔa Dehé The park was among the world's first four natural heritage locations to be inscribed as World Heritage Sites by UNESCO in 1978 because of its picturesque wild rivers, canyons, and waterfalls. The park is also said to be haunted or cursed, following the mysterious disappearances and deaths of several gold prospectors over the ...

Herbaceous
Herbaceous plants are vascular plants that have no persistent woody stems above ground. This broad category of plants includes many perennials, and nearly all annuals and biennials. Definitions of "herb" and "herbaceous" The fourth edition of the ''Shorter Oxford English Dictionary'' defines "herb" as: #"A plant whose stem does not become woody and persistent (as in a tree or shrub) but remains soft and succulent, and dies (completely or down to the root) after flowering"; #"A (freq. aromatic) plant used for flavouring or scent, in medicine, etc.". (See: Herb) The same dictionary defines "herbaceous" as: #"Of the nature of a herb; esp. not forming a woody stem but dying down to the root each year"; #"BOTANY Resembling a leaf in colour or texture. Opp. scarious". Botanical sources differ from each other on the definition of "herb". For instance, the Hunt Institute for Botanical Documentation includes the condition "when persisting over more than one growing season, the parts of ...

Plants Described In 1974
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have los ...

Flora Of The Northwest Territories
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Symphyotrichum
''Symphyotrichum'' () is a genus of over 100 species and naturally occurring hybrids of herbaceous annual and perennial plants in the composite family Asteraceae, most which were formerly treated within the genus ''Aster''. The majority are endemic to North America, but several also occur in the West Indies, Central and South America, as well as in eastern Eurasia. Several species have been introduced to Europe as garden specimens, most notably New England aster (''Symphyotrichum novae-angliae'') and New York aster (''Symphyotrichum novi-belgii''). Description Brouillet, et al. wrote: Taxonomy of ''Symphyotrichum'' is difficult. Species are usually heterophyllous, some strongly so. Individuals in the spring, with basal rosettes, often have leaf shapes quite different from those with cauline leaves seen later in the season. Phyllary shape on first- and later-formed heads may differ. Individuals may vary considerably in plant size and array development depending upon growing con ...

CBC News
CBC News is a division of the Canadian Broadcasting Corporation responsible for the news gathering and production of news programs on the corporation's English-language operations, namely CBC Television, CBC Radio, CBC News Network, and CBC.ca. Founded in 1941, CBC News is the largest news broadcaster in Canada and has local, regional, and national broadcasts and stations. It frequently collaborates with its organizationally separate French-language counterpart, Radio-Canada Info. History The first CBC newscast was a bilingual radio report on November 2, 1936. The CBC News Service was inaugurated during World War II on January 1, 1941, when Dan McArthur, chief news editor, had Wells Ritchie prepare for the announcer Charles Jennings a national report at 8:00 pm. Readers who followed Jennings were Lorne Greene, Frank Herbert and Earl Cameron. ''CBC News Roundup'' (French counterpart: ''La revue de l'actualité'') started on August 16, 1943, at 7:45 pm, being replaced by ''T ...

Mineral Spring
Mineral springs are naturally occurring springs that produces hard water, water that contains dissolved minerals. Salts, sulfur compounds, and gases are among the substances that can be dissolved in the spring water during its passage underground. In this they are unlike sweet springs, which produce soft water with no noticeable dissolved gasses. The dissolved minerals may alter the water's taste. Mineral water obtained from mineral springs, and the precipitated salts such as Epsom salt have long been important commercial products. Some mineral springs may contain significant amounts of harmful dissolved minerals, such as arsenic, and should not be drunk. Sulfur springs smell of rotten eggs due to hydrogen sulfide (H2S), which is hazardous and sometimes deadly. It is a gas, and it usually enters the body when it is breathed in. The quantities ingested in drinking water are much lower and are not considered likely to cause harm, but few studies on long-term, low-level exposu ...

Disk Floret
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more technically, ...
