Arnica Chamissonis
''Arnica chamissonis'', the Chamisso arnica, is a North American species of plants in the family Asteraceae. It is very similar to '' Arnica montana''. ''Arnica chamissonis'' is native to North America and naturalized in parts of Europe while ''A. montana'' is indigenous to Europe. Distribution and habitat ''Arnica chamissonis'' is native to western North America, including Alaska, and most of Canada including Yukon and Northwest Territories. ''Arnica chamissonis'' is perennial. It has a temperature minimum of . They are adapted to both coarse and medium textured soils with a pH between 6.0–7.2. Since this plant uses a lot of moisture, it has a precipitation requirement of between . It generally prefers moist meadows and conifer forests and often grows in montane to subalpine zone Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ec ...

Rhizomatous
In botany and dendrology, a rhizome (; , ) is a modified subterranean plant stem that sends out roots and shoots from its nodes. Rhizomes are also called creeping rootstalks or just rootstalks. Rhizomes develop from axillary buds and grow horizontally. The rhizome also retains the ability to allow new shoots to grow upwards. A rhizome is the main stem of the plant that runs underground horizontally. A stolon is similar to a rhizome, but a stolon sprouts from an existing stem, has long internodes, and generates new shoots at the end, such as in the strawberry plant. In general, rhizomes have short internodes, send out roots from the bottom of the nodes, and generate new upward-growing shoots from the top of the nodes. A stem tuber is a thickened part of a rhizome or stolon that has been enlarged for use as a storage organ. In general, a tuber is high in starch, e.g. the potato, which is a modified stolon. The term "tuber" is often used imprecisely and is sometimes applied to pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of The Sierra Nevada (United States)
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 Phy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flora Of Canada
The flora of Canada is quite diverse, due to the wide range of ecoregions and environmental conditions present in Canada. From the warm, temperate broadleaf forests of southern Ontario to the frigid Arctic plains of Northern Canada, from the wet temperate rainforests of the west coast to the arid deserts, badlands and tundra plains, the biodiversity of Canada's plants is extensive. According to environment Canada the nation of Canada hosts approximately 17,000 identified species of trees, flowers, herbs, ferns, mosses and other flora. About 4,100 species of vascular plants are native to Canada, and about 1,200 additional non-native species are recorded as established outside cultivation there.

Arnica
''Arnica'' is a genus of perennial plant, perennial, herbaceous plants in the sunflower family (Asteraceae). The genus name ''Arnica'' may be derived from the Greek language, Greek ''wikt:arni, arni'', "lamb", in reference to the plants' soft, hairy leaves. ''Arnica'' is also known by the names ''mountain tobacco'' and confusingly, ''leopard's bane'' and ''wolfsbane''—two names that it shares with the entirely unrelated genus ''Aconitum''. This Circumboreal Region, circumboreal and montane (subalpine) genus occurs mostly in the temperate regions of western North America, with a few species native to the Arctic Circle, Arctic regions of northern Eurasia and North America. ''Arnica'' species are used as food plants by the larvae of some Lepidoptera species, including ''Bucculatricidae, Bucculatrix arnicella''. ''Arnica'' was previously classified in the tribe Senecioneae because it has a flower or pappus (flower structure), pappus of fine bristles. Characteristics ''Arnica'' ...

Adelbert Von Chamisso
Adelbert von Chamisso (; 30 January 178121 August 1838) was a German poet and botanist, author of ''Peter Schlemihl'', a famous story about a man who sold his shadow. He was commonly known in French as Adelbert de Chamisso (or Chamissot) de Boncourt, a name referring to the family estate at Boncourt. Life The son of Louis Marie, Count of Chamisso, by his marriage to Anne Marie Gargam, Chamisso began life as Louis Charles Adélaïde de Chamissot at the ''château'' of Boncourt at Ante, in Champagne, France, the ancestral seat of his family. His name appears in several forms, one of the most common being ''Ludolf Karl Adelbert von Chamisso.''Rodolfo E.G. Pichi Sermolli. 1996. ''Authors of Scientific Names in Pteridophyta''. Royal Botanic Gardens, Kew. In 1790, the French Revolution drove his parents out of France with their seven children, and they went successively to Liège, the Hague, Würzburg, and Bayreuth, and possibly Hamburg, before settling in Berlin.

Helenalin
Helenalin, or (-)-4-Hydroxy-4a,8-dimethyl-3,3a,4a,7a,8,9,9a-octahydroazuleno ,5-b/nowiki>furan-2,5-dione, is a toxic sesquiterpene lactone which can be found in several plants such as ''Arnica montana'' and '' Arnica chamissonis'' Helenalin is responsible for the toxicity of the ''Arnica'' spp. Although toxic, helenalin possesses some ''in vitro'' anti-inflammatory and anti-neoplastic effects. Helenalin can inhibit certain enzymes, such as 5-lipoxygenase and leukotriene C4 synthase. For this reason the compound or its derivatives may have potential medical applications. Structure and reactivity Helenalin belongs to the group of sesquiterpene lactones which are characterised by a lactone ring. Beside this ring, the structure of helenalin has two reactive groups (α-methylene-γ-butyrolactone and a cyclopentenone group) that can undergo a Michael addition. The double bond in the carbonyl group can undergo a Michael addition with a thiol group, also called a sulfhydryl group. The ...

Adventitious Roots
Important structures in plant development are buds, shoots, roots, leaves, and flowers; plants produce these tissues and structures throughout their life from meristems located at the tips of organs, or between mature tissues. Thus, a living plant always has embryonic tissues. By contrast, an animal embryo will very early produce all of the body parts that it will ever have in its life. When the animal is born (or hatches from its egg), it has all its body parts and from that point will only grow larger and more mature. However, both plants and animals pass through a phylotypic stage that evolved independently and that causes a developmental constraint limiting morphological diversification. According to plant physiologist A. Carl Leopold, the properties of organization seen in a plant are emergent properties which are more than the sum of the individual parts. "The assembly of these tissues and functions into an integrated multicellular organism yields not only the characteris ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
