Cotula Coronopifolia
The small marsh flower ''Cotula coronopifolia'' bears the common names brass buttons, golden buttons, and buttonweed. The flower heads are bright yellow discoid heads that look like thick buttons. Individual plants spread stems along the ground and send up the knobby flowers at intervals. The plant is native to southern Africa, as well as New Zealand, but it has been introduced to other parts of the world (Europe, North + South America, etc.). Brass buttons are common plants that occupy a specialized ecological niche. They prefer muddy, anoxic wetlands and brackish water. They are very salt-tolerant. The plant has fat, fleshy leaves that store water during times of saline inundation. The reddish stems and green, blade-shaped leaves are coated with a shiny cuticle to retain moisture. It can also be found in the wetter patches in vernal pool ecosystems. Brass buttons are common along beaches, salt marshes, and estuaries from California to Washington. It has been present in the Brit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salt Marsh
A salt marsh or saltmarsh, also known as a coastal salt marsh or a tidal marsh, is a coastal ecosystem in the upper coastal intertidal zone between land and open saltwater or brackish water that is regularly flooded by the tides. It is dominated by dense stands of salt-tolerant plants such as herbs, grasses, or low shrubs. These plants are terrestrial in origin and are essential to the stability of the salt marsh in trapping and binding sediments. Salt marshes play a large role in the aquatic food web and the delivery of nutrients to coastal waters. They also support terrestrial animals and provide coastal protection. Salt marshes have historically been endangered by poorly implemented coastal management practices, with land reclaimed for human uses or polluted by upstream agriculture or other industrial coastal uses. Additionally, sea level rise caused by climate change is endangering other marshes, through erosion and submersion of otherwise tidal marshes. However, recent ackn ...

Plants Described In 1753
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 lost the ...

Cotula
''Cotula'' is a genus of flowering plant in the sunflower family. It includes plants known generally as water buttons or buttonweeds. The species within this genus can vary extensively in their habit, leaf division, involucre, receptacle and achenes. This makes it difficult to define them by comparing their morphology. The genus can only be defined by looking at the corollas of their flowers. Most are disciform (lacking ray florets). These corollas may be tubular, reduced or even absent. Another characteristic is their solitary heads growing on a peduncle. Taxonomy ''Cotula'' is the largest genus found in the Southern Hemisphere of the tribe Anthemideae. This genus was first mentioned by Carl Linnaeus, who described four species in his first edition (1753) of '' Species Plantarum''. In 1867 the genus was subdivided by George BenthamBentham, G., 1867: "Flora Australiensis", Vol. 3. Reeve, London. into three sections. Since his account, only a few changes have been made but ...

Fir Island (Washington)
Fir Island is bounded by North and South Forks of the Skagit River and Skagit Bay of Puget Sound in the southwestern corner of Skagit County, Washington. Triangular in outline, east–west by north–south with an area of nearly , Fir Island is occupied by 195 families. The island is connected by bridge to the village of Conway, located on the east shore of the South Fork of the Skagit River. A second bridge, across the North Fork of the Skagit River, leads to La Conner, northwest. Near the northeast tip of Fir Island is the site of the 19th-century town of Skagit City which declined after upstream log jams were removed in 1877. Natural history A major component of the Skagit River Delta, the island is an important habitat for wildlife. Migrating from the northern portion of Wrangel Island in Russia, 30,000 to 70,000 snow geese spend the winter on the Skagit River Delta and the Fraser River Delta of British Columbia. Important internationally, this population and one ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Entire Leaf
The following is a list of terms which are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (a single leaf blade or lamina) or compound (with several leaflets). The edge of the leaf may be regular or irregular, may be smooth or bearing hair, bristles or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf article. The terms listed here all are supported by technical and professional usage, but they cannot be represented as mandatory or undebatable; readers must use their judgement. Authors often use terms arbitrarily, or coin them to taste, possibly in ignorance of established terms, and it is not always clear whether because of ignorance, or personal preference, or because usages change with time or context, or because of variation between specimens, even specimens from the same plant. For example, whether to call leaves on the same tree "acuminate", "lanceolate", or "linear" could ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Invasive Species In The United States
Invasive species are a significant threat to many native habitats and species of the United States and a significant cost to agriculture, forestry, and recreation. The term "invasive species" can refer to introduced/naturalized species, feral species, or introduced diseases. Some introduced species, such as the dandelion, do not cause significant economic or ecologic damage and are not widely considered as invasive. Economic damages associated with invasive species' effects and control costs are estimated at $120 billion per year. Notable invasive species } , - , , , , Giant African land snail , , ''Lissachatina fulica'' , , Florida , , Pest control , , This invasive species was smuggled into Florida from Africa.

Neophyte (botany)
In botany, a neophyte (from Greek νέος (''néos'') "new" and φυτόν (''phutón'') "plant") is a plant species which is not native to a geographical region and was introduced in recent history. Non-native plants that are long-established in an area are called archaeophytes. In Britain, neophytes are defined more specifically as plant species that were introduced after 1492, when Christopher Columbus arrived in the New World and the Columbian Exchange began. Terminology The terminology of the invasion biology is very uneven. In the English-speaking world, terms such as invasive species or the like are mainly used, which is interpreted differently and do not differentiate between different groups of animals or characteristics of the species. The International Union for Conservation of Nature and Natural Resources (IUCN) differentiates in its definitions between alien species and invasive alien species; Alien species are species that have been introduced into a foreign area ...
