Arnica Intermedia
''Arnica latifolia'' is a species of arnica in the sunflower family, known by the common names broadleaf arnica, broad leaved arnica, mountain arnica, and daffodil leopardbane. It is native to western North America from Alaska east to Northwest Territories and south to Mono County, California, and Taos County, New Mexico. It grows in mountain habitat such as forest and meadows. ''Arnica latifolia'' is a perennial herb growing from a long rhizome and producing a hairy, mostly naked stem 10 to 50 centimeters tall. It has a cluster of leaves around its base and usually a few pairs along the lower part of the stem. The leaves are lance-shaped to broad and nearly heart-shaped, and are usually toothed. The inflorescence contains one or more daisy-like flower heads lined in glandular phyllaries. Each has a center of yellow disc florets and several yellow ray florets up to 3 centimeters long. The fruit is an achene with a white pappus. The plant was first described in 1832 by German- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Disc 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 ...

Flora Of The Northwestern 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plants Described In 1832
Plants are predominantly Photosynthesis, photosynthetic eukaryotes of the Kingdom (biology), 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 Glaucophyte, Glaucophyta, and consists of the green algae and Embryophyte, Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and Fern ally, 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 colo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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'' ...

Russian America
Russian America (russian: Русская Америка, Russkaya Amerika) was the name for the Russian Empire's colonial possessions in North America from 1799 to 1867. It consisted mostly of present-day Alaska in the United States, but also included small outposts in California, including Fort Ross, and three forts in Hawaii, including Russian Fort Elizabeth. Russian Creole settlements were concentrated in Alaska, including the capital, Novo-Arkhangelsk (''New Arkhangelsk''), which is now Sitka. After first landing in Alaska in 1741, Vitus Bering claimed the Alaskan country for the Russian Empire. Russia later confirmed its rule over the territory with the ''Ukase'' of 1799 which established the southern border of Russian America along the 55th parallel north.United Kingdom of Great Britain and Ireland''Text of Ukase of 1779''in ''Behring sea arbitration'' (London: Harrison and Sons, 1893), pp. 25-27 The decree also provided monopolistic privileges to the state-sponsor ...

Gustav Heinrich Von Bongard
August Gustav Heinrich von Bongard (12 September 1786 – 1839) was a German botanist who worked in Saint Petersburg, Russia. Born in Bonn, he was among the first botanists to describe the new plants then being discovered in Alaska (under Russian ownership at the time), including species now of major commercial importance like Sitka Spruce and Red Alder. The specimens he described were mostly collected by Carl Mertens at Sitka, Alaska. The plant genus ''Bongardia'' (family Berberidaceae) is named in his honor.

Pappus (flower Structure)
In Asteraceae, the pappus is the modified calyx, the part of an individual floret, that surrounds the base of the corolla tube in flower. It functions as a wind-dispersal mechanism for the seeds. The term is sometimes used for similar structures in other plant families e.g. in certain genera of the Apocynaceae, although the pappus in Apocynaceae is not derived from the calyx of the flower. In Asteraceae, the pappus may be composed of bristles (sometimes feathery), awns, scales, or may be absent, and in some species, is too small to see without magnification. In genera such as ''Taraxacum'' or ''Eupatorium'', feathery bristles of the pappus function as a "parachute" which enables the seed to be carried by the wind. The name derives from the Ancient Greek word ''pappos'', Latin ''pappus'', meaning "old man", so used for a plant (assumed to be an ''Erigeron'' species) having bristles and also for the woolly, hairy seed of certain plants. The pappus of the dandelion plays a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
