Suksdorfia Violacea
''Suksdorfia violacea'' is an uncommon species of herbaceous flowering plant in the saxifrage family known by the common name violet suksdorfia. In 1879 Asa Gray named the genus ''Suksdorfia'' after Wilhelm Nikolaus Suksdorf who had first collected a specimen of ''S. violacea'' in 1878 near Mount Adams-White Salmon, Washington and sent it to Gray for assistance in classifying it. Gray and Suksdorf had a long and close working relationship, and Gray initially identified and named various species found by Suksdorf. Its conservation status has been rated by NatureServe as "G4 – Apparently Secure". Taxonomy ''Suksdorfia violacea'' is the type species for this genus and Gray named it after Suksdorf. The genus name ''Hemieva'' Raf. was published earlier than ''Suksdorfia'', but was less well known, and ''Suksdorfia'' is now a conserved name. Therefore, ''Hemieva violacea'', although correct when it was published in 1896 is no longer the correct name for this species. Ecology ' ...

Asa Gray
Asa Gray (November 18, 1810 – January 30, 1888) is considered the most important American botanist of the 19th century. His ''Darwiniana'' was considered an important explanation of how religion and science were not necessarily mutually exclusive. Gray was adamant that a genetic connection must exist between all members of a species. He was also strongly opposed to the ideas of hybridization within one generation and special creation in the sense of its not allowing for evolution. He was a strong supporter of Darwin, although Gray's theistic evolution was guided by a Creator. As a professor of botany at Harvard University for several decades, Gray regularly visited, and corresponded with, many of the leading natural scientists of the era, including Charles Darwin, who held great regard for him. Gray made several trips to Europe to collaborate with leading European scientists of the era, as well as trips to the southern and western United States. He also built an extensive ne ...

Saxifragaceae
Saxifragaceae is a family of herbaceous perennial flowering plants, within the core eudicot order Saxifragales. The taxonomy of the family has been greatly revised and the scope much reduced in the era of molecular phylogenetic analysis. The family is divided into ten clades, with about 640 known species in about 35 accepted genera. About half of these consist of a single species, but about 400 of the species are in the type genus ''Saxifraga''. The family is predominantly distributed in the northern hemisphere, but also in the Andes in South America. Description Species are herbaceous perennials (rarely annual or biennial), sometimes succulent or xerophytic, often with perennating rhizomes. The leaves are usually basally aggregated in alternate rosettes, sometimes on inflorescence stems. They are usually simple, rarely pinnately or palmately compound. Their margins may be entire, deeply lobed, cleft, crenate or dentate and petiolate with stipules. The inflorescences are b ...

Suksdorfia
''Suksdorfia'' is a genus in the family Saxifragaceae. It has only two accepted species, '' Suksdorfia alchemilloides'' and '' Suksdorfia violacea'', native to central South America and northwestern North America, respectively. Asa Gray named the genus ''Suksdorfia'' after Wilhelm Nikolaus Suksdorf, a mostly self-taught German botanist who came to the United States at age eight and found the species ''S. violacea'' in the northwestern United States. ''S. violacea'' is the type species In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specime ... for this genus. Since the International Rules of Botanical Nomenclature of 1906, the genus name ''Suksdorfia'' Gray, published in 1879, has been conserved against the earlier name ''Hemieva'' Raf., which had been published in 1837 with the type sp ...

Wilhelm Nikolaus Suksdorf
Wilhelm Nikolaus Suksdorf (September 15, 1850 – October 3, 1932) was a German–American botanist who specialized in the flora of the Pacific Northwest. He was largely self-taught and is considered one of the top three self-taught botanists of his era for the Pacific Northwest, alongside Thomas Jefferson Howell and William Conklin Cusick. Early life Suksdorf was born on September 15, 1850 in the small village of Dransau, along the eastern border of Schleswig, but it is often listed as the nearby large city of Kiel, Germany. His parents were Detlev Suksdorf, a tenant farmer, and Louise Schröder Suksdorf, who had nine children. Two of these children were girls who died young. The seven boys all lived well into adulthood. Suksdorf was the 6th child and 2nd-youngest son. At age eight, Suksdorf's family moved to Davenport, Iowa, where he lived until 1874. After a few years as a tenant farmer, Suksdorf's father bought 100 acres of unbroken prairie, where the family lived an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Adams (Washington)
Mount Adams, known by some Native American tribes as Pahto or Klickitat, is a potentially active stratovolcano in the Cascade Range. Although Adams has not erupted in more than 1,000 years, it is not considered extinct. It is the second-highest mountain in Washington, after Mount Rainier. Adams, named for President John Adams, is a member of the Cascade Volcanic Arc, and is one of the arc's largest volcanoes, located in a remote wilderness approximately east of Mount St. Helens. The Mount Adams Wilderness consists of the upper and western part of the volcano's cone. The eastern side of the mountain is designated as part of the territory of the Yakama Nation. Adams' asymmetrical and broad body rises above the Cascade crest. Its nearly flat summit was formed as a result of cone-building eruptions from separated vents. The Pacific Crest Trail traverses the western flank of the mountain. Geography General Mount Adams stands east of Mount St. Helens and about south of ...

White Salmon, Washington
White Salmon is a city in Klickitat County, Washington, Klickitat County, Washington (state), Washington, United States. It is located in the Columbia River Gorge. The population was 2,193 at the 2000 United States Census, 2000 census and increased 1.4% to 2,224 at the 2010 United States Census, 2010 census. History White Salmon was first settled in 1852 by Erastus Joslyn and his wife. White Salmon was officially incorporated on June 3, 1907. White Salmon was part of the home of the Klickitat people, Klickitat Tribe, now a part of the Yakama Confederated Nations. The Klickitat Tribe sold some land to the Joslyns. They were generally Native advocates for the time. The area was thrown open on October 31, 1858 for white settlement after the Klickitat and Yakama lost the fight for their homelands in the Yakama War. Within the same year, the region was very rapidly and heavily settled by white immigrants making land claims. The Klickitat were forced to relocate to the Yakama Reserv ...

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

Conserved Name
A conserved name or ''nomen conservandum'' (plural ''nomina conservanda'', abbreviated as ''nom. cons.'') is a scientific name that has specific nomenclatural protection. That is, the name is retained, even though it violates one or more rules which would otherwise prevent it from being legitimate. ''Nomen conservandum'' is a Latin term, meaning "a name to be conserved". The terms are often used interchangeably, such as by the ''International Code of Nomenclature for Algae, Fungi, and Plants'' (ICN), while the ''International Code of Zoological Nomenclature'' favours the term "''conserved name''". The process for conserving botanical names is different from that for zoological names. Under the botanical code, names may also be "suppressed", ''nomen rejiciendum'' (plural ''nomina rejicienda'' or ''nomina utique rejicienda'', abbreviated as ''nom. rej.''), or rejected in favour of a particular conserved name, and combinations based on a suppressed name are also listed as “''nom. re ...

Petiole (botany)
In botany, the petiole () is the stalk that attaches the leaf blade to the stem, and is able to twist the leaf to face the sun. This gives a characteristic foliage arrangement to the plant. Outgrowths appearing on each side of the petiole in some species are called stipules. Leaves with a petiole are said to be petiolate, while leaves lacking a petiole are called sessile or apetiolate. Description The petiole is a stalk that attaches a leaf to the plant stem. In petiolate leaves, the leaf stalk may be long, as in the leaves of celery and rhubarb, or short. When completely absent, the blade attaches directly to the stem and is said to be sessile. Subpetiolate leaves have an extremely short petiole, and may appear sessile. The broomrape family Orobanchaceae is an example of a family in which the leaves are always sessile. In some other plant groups, such as the speedwell genus '' Veronica'', petiolate and sessile leaves may occur in different species. In the grasses (Poaceae), ...

Calyx (flower)
A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 The term ''sepalum'' was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively the sepals are called the calyx (plural calyces), the outermost whorl of parts that form a flower. The word ''calyx'' was adopted from the Latin ,Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 not to be confused with 'cup, goblet'. ''Calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet', and the words have been used interchangeably in botanical Latin. After flowering, most plants have no more use for the calyx which withers or becomes vestigial. Some plants retain a thorny calyx, either dried or live, as ...

Stamens
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains ''microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in '' Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea''). The androecium in vario ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
