Schefflera Venulosa 20a
''Schefflera'' is a genus of flowering plants in the family Araliaceae. With an estimated 600–900 species, the genus represents about half of its family. The plants are trees, shrubs or lianas, growing tall, with woody stems, the absence of articulated pedicels and armaments, and palmately compound leaves. Several species are grown in pots as houseplants, most commonly ''Schefflera actinophylla'' (umbrella tree) and ''Schefflera arboricola'' (dwarf umbrella tree). Numerous cultivars have been selected for various characters, most popularly for variegated or purple foliage. ''Schefflera'' species are used as food plants by the larvae of some Lepidopteran species including ''Batrachedra arenosella'' (recorded on ''S. stellata''). ''Schefflera arboricola'' and ''Schefflera actinophylla'' can be used to attract birds. The genus is named in honor of Johann Peter Ernst von Scheffler (born in 1739), physician and botanist of Gdańsk, and later of Warsaw, who contributed plants to G ...

Schefflera Arboricola
''Heptapleurum arboricola'' (syn. ''Schefflera arboricola'', ) is a flowering plant in the family Araliaceae, native to Taiwan and Hainan Province, China. Its common name is dwarf umbrella tree, as it resembles a smaller version of the umbrella tree, '' Heptapleurum actinophyllum''. Description It is an evergreen shrub growing to 8–9 m tall, free-standing, or clinging to the trunks of other trees as an epiphyte. The leaves are palmately compound, with 7–9 leaflets, the leaflets 9–20 cm long and 4–10 cm broad (though often smaller in cultivation) with a wedge-shaped base, entire margin, and an obtuse or acute apex, sometimes emarginate. The leaves are leathery in texture, shiny green, glabrous on the upper surface and somewhat lighter and matte on the underside. Young plants have smaller leaves and fewer leaflets. Each leaflet has a central rib that divides it into two halves, with between four and six ribs clearly visible up to the third order. The stipules merge with ...

Gottfried Reyger
Gottfried is a masculine German given name. It is derived from the Old High German name , recorded since the 7th century. The name is composed of the elements (conflated from the etyma for 'God' and 'good', and possibly further conflated with ) and ('peace, protection'). The German name was commonly hypocoristically abbreviated as ''Götz'' from the late medieval period. ''Götz'' and variants (including '' Göthe, Göthke'' and ''Göpfert'') also came into use as German surnames. Gottfried is a common Jewish surname as well. Given name The given name ''Gottfried'' became extremely frequent in Germany in the High Middle Ages, to the point of eclipsing most other names in ''God-'' (such as ''Godabert, Gotahard, Godohelm, Godomar, Goduin, Gotrat, Godulf'', etc.) The name was Latinised as ''Godefridus''. Medieval bearers of the name include: *Gotfrid, Duke of Alemannia and Raetia (d. 709) *Godefrid (d. c. 720), son of Drogo of Champagne, Frankish nobleman. *Godfrid Haraldsson ...

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Parallel Evolution
Parallel evolution is the similar development of a trait in distinct species that are not closely related, but share a similar original trait in response to similar evolutionary pressure.Zhang, J. and Kumar, S. 1997Detection of convergent and parallel evolution at the amino acid sequence level. ''Mol. Biol. Evol.'' 14, 527-36. Parallel vs. convergent evolution Given a particular trait that occurs in each of two lineages descended from a specified ancestor, it is possible in theory to define parallel and convergent evolutionary trends strictly, and distinguish them clearly from one another. However the criteria for defining convergent as opposed to parallel evolution often are unclear in practice, so that arbitrary diagnosis is common in some cases. When two species are similar in a particular character, evolution is defined as parallel if the ancestors shared that similarity; if they did not, the evolution of that character in those species is defined as convergent. However, thi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Systematic Botany
Plant taxonomy is the science that finds, identifies, describes, classifies, and names plants. It is one of the main branches of taxonomy (the science that finds, describes, classifies, and names living things). Plant taxonomy is closely allied to plant systematics, and there is no sharp boundary between the two. In practice, "plant systematics" involves relationships between plants and their evolution, especially at the higher levels, whereas "plant taxonomy" deals with the actual handling of plant specimens. The precise relationship between taxonomy and systematics, however, has changed along with the goals and methods employed. Plant taxonomy is well known for being turbulent, and traditionally not having any close agreement on circumscription and placement of taxa. See the list of systems of plant taxonomy. Background Classification systems serve the purpose of grouping organisms by characteristics common to each group. Plants are distinguished from animals by various trai ...

Polyphyletic
A polyphyletic group is an assemblage of organisms or other evolving elements that is of mixed evolutionary origin. The term is often applied to groups that share similar features known as homoplasies, which are explained as a result of convergent evolution. The arrangement of the members of a polyphyletic group is called a polyphyly .. ource for pronunciation./ref> It is contrasted with monophyly and paraphyly. For example, the biological characteristic of warm-bloodedness evolved separately in the ancestors of mammals and the ancestors of birds; "warm-blooded animals" is therefore a polyphyletic grouping. Other examples of polyphyletic groups are algae, C4 photosynthetic plants, and edentates. Many taxonomists aim to avoid homoplasies in grouping taxa together, with a goal to identify and eliminate groups that are found to be polyphyletic. This is often the stimulus for major revisions of the classification schemes. Researchers concerned more with ecology than with systema ...

Circumscription (taxonomy)
In biological taxonomy, circumscription is the content of a taxon, that is, the delimitation of which subordinate taxa are parts of that taxon. If we determine that species X, Y, and Z belong in Genus A, and species T, U, V, and W belong in Genus B, those are our circumscriptions of those two genera. Another systematist might determine that T, U, V, W, X, Y, and Z all belong in genus A. Agreement on circumscriptions is not governed by the Codes of Zoological or Botanical Nomenclature, and must be reached by scientific consensus. A goal of biological taxonomy is to achieve a stable circumscription for every taxon. This goal conflicts, at times, with the goal of achieving a natural classification that reflects the evolutionary history of divergence of groups of organisms. Balancing these two goals is a work in progress, and the circumscriptions of many taxa that had been regarded as stable for decades are in upheaval in the light of rapid developments in molecular phylogenetics ...

West Carpathians
The Western Carpathians are a mountain range and geomorphological province that forms the western part of the Carpathian Mountains. The mountain belt stretches from the Low Beskids range of the Eastern Carpathians along the border of Poland with Slovakia toward the Moravian region of the Czech Republic and the Austrian Weinviertel. In the south the North Hungarian Mountains cover northern Hungary. The area of the Western Carpathians comprises about 70,000 km². The highest elevation is the Gerlachovský štít (2,655m). Geographical definition Most of the perimeter of the Western Carpathians is quite sharply defined by valleys. To the northwest and north they are separated from the Bohemian Massif by the Forecarpathian Lowland and the Lesser Poland Upland; to the west the Moravian Gate leads over to the Sudetes. To the south the mountain chain falls away towards the Pannonian Plain, a large plain situated between the Alps, the Dinaric Alps, and the main mass of the Easte ...
