Pulsatilla Occidentalis
''Pulsatilla occidentalis'', synonym ''Anemone occidentalis'', the white pasqueflower or western pasqueflower, is a herbaceous species of flowering plant in the buttercup family Ranunculaceae. Individuals are tall, from caudices, with three to six leaves at the base of the plant that are 3-foliolate, each leaflet pinnatifid to dissected in shape. Leaf petioles are long. Leaves have villous hairs and their margins are pinnatifid or dissected. Plants flower briefly mid-spring to mid-summer, usually soon after the ground is exposed by melting snow. The flowers are composed of five to seven sepals (sometimes called tepals), normally white or soft purple, also mixed white and blueish purple, one flower per stem. The sepals are long and wide. Flowers have 150–200 stamens. The fruit occurs in heads rounded to subcylindric in shape, with pedicels long. The achenes are ellipsoid in shape, not winged, covered with villous hairs, with beaks curved that reflex as they age and long, fe ...

Achene
An achene (; ), also sometimes called akene and occasionally achenium or achenocarp, is a type of simple dry fruit produced by many species of flowering plants. Achenes are monocarpellate (formed from one carpel) and indehiscent (they do not open at maturity). Achenes contain a single seed that nearly fills the pericarp, but does not adhere to it. In many species, what is called the "seed" is an achene, a fruit containing the seed. The seed-like appearance is owed to the hardening of the fruit wall (pericarp), which encloses the solitary seed so closely as to seem like a seed coat. Examples The fruits of buttercup, buckwheat, caraway, quinoa, amaranth, and cannabis are typical achenes. The achenes of the strawberry are sometimes mistaken for seeds. The strawberry is an accessory fruit with an aggregate of achenes on its outer surface, and what is eaten is accessory tissue. A rose produces an aggregate of achene fruits that are encompassed within an expanded hypanthium ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aglycone
An aglycone (aglycon or genin) is the compound remaining after the glycosyl group on a glycoside is replaced by a hydrogen atom. For example, the aglycone of a cardiac glycoside would be a steroid A steroid is a biologically active organic compound with four rings arranged in a specific molecular configuration. Steroids have two principal biological functions: as important components of cell membranes that alter membrane fluidity; and ... molecule. Detection A way to identify aglycone is proposed to extract it from Agave spp. by using H-NMR and Heteronuclear multiple bond correlation (HMBC) experiments. The HMBC experiment can be combined with other techniques such as mass spectrometry to further examine the structure and the function of aglycone. Samples of glycones and glycosides from limonoids can be simultaneously quantified through a high performance liquid chromatography (HPLC) method, where a binary solvent system and a diode array detector separate and detect th ...

Flora Of The Southwestern United States
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. 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 Thurm ...

Pulsatilla
The genus ''Pulsatilla'' contains about 40 species of herbaceous perennial plants native to meadows and prairies of North America, Europe, and Asia. Derived from the Hebrew word for Passover, "pasakh", the common name pasque flower refers to the Easter (Passover) flowering period, in the spring. Common names include pasque flower (or pasqueflower), wind flower, prairie crocus, Easter flower, and meadow anemone. Several species are valued ornamentals because of their finely-dissected leaves, solitary bell-shaped flowers, and plumed seed heads. The showy part of the flower consists of sepals, not petals. Taxonomy The genus ''Pulsatilla'' was first formally named in 1754 by the English botanist Philip Miller. The type species is '' Pulsatilla vulgaris'', the European pasque flower. It is sometimes considered a subgenus under the genus ''Anemone'' or as an informally named "group" within ''Anemone'' subg. ''Anemone'' sect. ''Pulsatilloides''.

Mount Rainier
Mount Rainier (), indigenously known as Tahoma, Tacoma, Tacobet, or təqʷubəʔ, is a large active stratovolcano in the Cascade Range of the Pacific Northwest, located in Mount Rainier National Park about south-southeast of Seattle. With a summit elevation of , it is the highest mountain in the U.S. state of Washington and the Cascade Range, the most topographically prominent mountain in the contiguous United States, and the tallest in the Cascade Volcanic Arc. Due to its high probability of eruption in the near future, Mount Rainier is considered one of the most dangerous volcanoes in the world, and it is on the Decade Volcano list. The large amount of glacial ice means that Mount Rainier could produce massive lahars that could threaten the entire Puyallup River valley. According to the United States Geological Survey, "about 80,000 people and their homes are at risk in Mount Rainier's lahar-hazard zones." Between 1950 and 2018, 439,460 people climbed Mount Rainier. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kootenay National Park
Kootenay National Park is a national park of Canada located in southeastern British Columbia. The park consists of of the Canadian Rockies, including parts of the Kootenay and Park mountain ranges, the Kootenay River and the entirety of the Vermilion River. While the Vermilion River is completely contained within the park, the Kootenay River has its headwaters just outside the park boundary, flowing through the park into the Rocky Mountain Trench and eventually joining the Columbia River. The park ranges in elevation from at the southwestern park entrance to at Deltaform Mountain. Initially called "Kootenay Dominion Park", the park was created in 1920 as part of an agreement between the province of British Columbia and the Canadian federal government to build a highway in exchange for title to a strip of land, approximately on either side of the 94 km route, the Banff–Windermere Highway, to be used solely for park purposes. While the park is open all year, the major ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Banff National Park
Banff National Park is Canada's oldest national park, established in 1885 as Rocky Mountains Park. Located in Alberta's Rocky Mountains, west of Calgary, Banff encompasses of mountainous terrain, with many glaciers and ice fields, dense coniferous forest, and alpine landscapes. The Icefields Parkway extends from Lake Louise, connecting to Jasper National Park in the north. Provincial forests and Yoho National Park are neighbours to the west, while Kootenay National Park is located to the south and Kananaskis Country to the southeast. The main commercial centre of the park is the town of Banff, in the Bow River valley. The Canadian Pacific Railway was instrumental in Banff's early years, building the Banff Springs Hotel and Chateau Lake Louise, and attracting tourists through extensive advertising. In the early 20th century, roads were built in Banff, at times by war internees from World War I, and through Great Depression-era public works projects. Since the 1960s, park acc ...

Glycoside
In chemistry, a glycoside is a molecule in which a sugar is bound to another functional group via a glycosidic bond. Glycosides play numerous important roles in living organisms. Many plants store chemicals in the form of inactive glycosides. These can be activated by enzyme hydrolysis, which causes the sugar part to be broken off, making the chemical available for use. Many such plant glycosides are used as medications. Several species of '' Heliconius'' butterfly are capable of incorporating these plant compounds as a form of chemical defense against predators. In animals and humans, poisons are often bound to sugar molecules as part of their elimination from the body. In formal terms, a glycoside is any molecule in which a sugar group is bonded through its anomeric carbon to another group via a glycosidic bond. Glycosides can be linked by an O- (an '' O-glycoside''), N- (a ''glycosylamine''), S-(a '' thioglycoside''), or C- (a ''C-glycoside'') glycosidic bond. According ...

Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, '' Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia l ...
