Helianthus Eggertii
''Helianthus eggertii'', known as Eggert's sunflower, is a North American species of flowering plants in the family Asteraceae. It is native to Tennessee, Kentucky, South Carolina, and Alabama. It is best known as one of the few plants to have been delisted under the Endangered Species Act because of the species' recovery. It was described by John Kunkel Small in 1903. Description ''Helianthus eggertii'' may grow to over tall, with erect, hairless stems. The leaves are borne on the stem, mostly in opposite pairs. These leaves are lanceolate to ovate, long by wide, narrowing towards the base. Each stem carries 1–5 flower heads, each on a peduncle long. Each flower head is in diameter, with 30–38 lanceolate phyllaries around the base. The flower head is hemispherical, and contains 10–18 yellow ray florets surrounding over 70 disc florets. ''Helianthus eggertii'' is very similar to the related species '' H. strumosus'' and '' H. laevigatus''. It differs from th ...

Flora Of North America
The ''Flora of North America North of Mexico'' (usually referred to as ''FNA'') is a multivolume work describing the native plants and naturalized plants of North America, including the United States, Canada, St. Pierre and Miquelon, and Greenland. It includes bryophytes and vascular plants. All taxa are described and included in dichotomous keys, distributions of all species and infraspecific taxa are mapped, and about 20% of species are illustrated with line drawings prepared specifically for FNA. It is expected to fill 30 volumes when completed and will be the first work to treat all of the known flora north of Mexico; in 2015 it was expected tha the series would conclude in 2017.

Specific Name (botany)
A botanical name is a formal scientific name conforming to the '' International Code of Nomenclature for algae, fungi, and plants'' (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the ''International Code of Nomenclature for Cultivated Plants'' (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae (Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia)." The purpose of a formal name is to have a single name that is accepted and used worldwide for a particular plant or plant group. For example, the botanical name ''Bellis perennis'' denotes a plant species which is native to most of the countries of Europe and the Middle East, where it has accumulated various names in many languages. Later, the plant was introdu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Locality (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost a ...

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Echinacea Tennesseensis
''Echinacea tennesseensis'', also known as the Tennessee coneflower or Tennessee purple coneflower, is a flowering plant in the family Asteraceae, endemic to the cedar glades of the central portion of the U.S. state of Tennessee. Description ''Echinacea tennesseensis'' is a herbaceous perennial plant growing to tall. The leaves are hairy, lanceolate, and arranged in a basal whorl with only a few small leaves on the flower stems. The flowers are produced in a capitulum (flowerhead) up to 8 cm (3.2 inches) broad, with a ring of purple ray florets surrounding the brown disc florets. A noticeable characteristic is its generally erect ray flowers, in contrast to the more drooping rays of its most similar congener, '' E. angustifolia'' (widespread throughout the prairie of the central U.S.) and other common ''Echinacea'' species such as '' E. purpurea''. Distribution ''Echinacea tennesseensis'' is a rare species, found in fewer than 10 locations in Davidson, Wilson, and Ru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Potentilla Robbinsiana
''Potentilla robbinsiana'', the dwarf mountain cinquefoil or Robbins' cinquefoil, is a small, yellow-flowered, perennial found exclusively above the tree line in the White Mountains of New Hampshire. The plant is nearly stemless and measures two to four centimeters in diameter. History The Crawford Path of Mount Washington, the oldest mountain hiking trail in America, was laid out in 1819 as a bridle path from Crawford Notch to the summit.Condensed Facts About Mount Washington, Atkinson News Co., 1912. There is some discrepancy as to who discovered ''Potentilla robbinsiana'', which some sources giving credit to its discovery in 1824 by English botanist and zoologist Thomas Nuttall, five years after completion of the Crawford Path. The more likely case is its discovery in 1829 by James Robbins. After its discovery it was described by the botanist and explorer William Oakes. It was soon recognized as a rare plant and over 850 specimens were collected and occasionally sold com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sales and Usage 2006 and 2007: Market Estimates. Summary in press releasMain page for EPA reports on pesticide use ihere Selective herbicides control specific weed species, while leaving the desired crop relatively unharmed, while non-selective herbicides (sometimes called total weedkillers in commercial products) can be used to clear waste ground, industrial and construction sites, railways and railway embankments as they kill all plant material with which they come into contact. Apart from selective/non-selective, other important distinctions include ''persistence'' (also known as ''residual action'': how long the product stays in place and remains active), ''means of uptake'' (whether it is absorbed by above-ground foliage only, through the roots, or by other means), and ''mechanism of action'' (how it works).

Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
