Augustin Pyramus De Candolle
Augustin Pyramus (or Pyrame) de Candolle (, , ; 4 February 17789 September 1841) was a Swiss botanist. René Louiche Desfontaines launched de Candolle's botanical career by recommending him at a herbarium. Within a couple of years de Candolle had established a new genus, and he went on to document hundreds of plant families and create a new natural plant classification system. Although de Candolle's main focus was botany, he also contributed to related fields such as phytogeography, agronomy, paleontology, medical botany, and economic botany. De Candolle originated the idea of "Nature's war", which influenced Charles Darwin and the principle of natural selection. de Candolle recognized that multiple species may develop similar characteristics that did not appear in a common evolutionary ancestor; a phenomenon now known as convergent evolution. During his work with plants, de Candolle noticed that plant leaf movements follow a near-24-hour cycle in constant light, suggestin ...

Ignatz Urban
Ignatz Urban (7 January 1848 – 7 January 1931) was a German botanist. He is known for his contributions to the flora of the Caribbean and Brazil, and for his work as curator of the Berlin Botanical Garden. Born the son of a brewer, Urban showed an interest in botany as an undergraduate. He pursued further study at the University of Bonn and later at the University of Berlin where he gained a doctorate in 1873. Urban was appointed by A. W. Eichler to run the Berlin Botanical Garden and supervised its move to Dahlem. He also worked as Eichler's assistant on the ''Flora Brasiliensis'', later succeeding him as editor. In 1884 Urban began working with Leopold Krug on his Puerto Rican collections, a collaboration would later produce the nine-volume '' Symbolae Antillanae'', one of his most important contributions, and his 30-part ''Sertum Antillanum''. Urban's herbarium, estimated to include 80,000 or more sheets, was destroyed when the Berlin Herbarium was bombed in 1943 ...

Soil Erosion
Soil erosion is the denudation or wearing away of the upper layer of soil. It is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice (glaciers), snow, air (wind), plants, and animals (including humans). In accordance with these agents, erosion is sometimes divided into water erosion, glacial erosion, snow erosion, wind (aeolean) erosion, zoogenic erosion and anthropogenic erosion such as tillage erosion. Soil erosion may be a slow process that continues relatively unnoticed, or it may occur at an alarming rate causing a serious loss of topsoil. The loss of soil from farmland may be reflected in reduced crop production potential, lower surface water quality and damaged drainage networks. Soil erosion could also cause sinkholes. Human activities have increased by 10–50 times the rate at which erosion is occurring world-wide. Excessive (or accelerated) erosion causes both "on-site" and "off-site" problems. On- ...

Leaf Shape
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] |

Macroptilium Lathyroides
''Macroptilium lathyroides'' is a species of plant in the legume family (Fabaceae) commonly known as the phasey bean. It is the type species of genus '' Macroptilium''. Herbaceous annual or short-lived perennial growing up to 1 m high, it is native to the tropical and subtropical areas of Central and South America, and naturalized throughout the tropics. It is cultivated for forage or as a green manure or cover crop in rotation. As it quickly spreads on disturbed soils, it is considered an environmental weed in some areas. Description ''M. lathyroides'' is a herbaceous annual or short-lived perennial, 0.6–1 m tall. The leaves are compound with three ovate to lanceolate leaflets, 3–8 cm long and 1–3.5 cm wide. Red to purple flowers, with wing petals larger than the lower petals, develop on long stalks. They grow paired long pods, 5.5–12 cm long, 2.5–3 mm wide, which readily shatter when mature, containing numerous seeds dispersed by winds. Seads ...

Phaseoleae
The plant tribe Phaseoleae is one of the subdivisions of the legume subfamily Faboideae, in the unranked NPAAA clade. This group includes many of the beans cultivated for human and animal food, most importantly from the genera ''Glycine'', '' Phaseolus'', and ''Vigna''. Taxonomy Although the tribe as defined in the late 20th century does not appear to be monophyletic, there does seem to be a monophyletic group which roughly corresponds to the tribe Phaseoleae (with some changes). The earlier concept of Phaseoleae is paraphyletic relative to the tribes Abreae and Psoraleeae, plus most of Millettieae and parts of Desmodieae. The following subtribes and genera are recognized by the USDA: ollow tribe links and genera lists for the accepted genera in each tribe/ref> ;Cajaninae * '' Adenodolichos'' Harms * ''Bolusafra'' Kuntze * ''Cajanus'' Adans. * ''Carrissoa'' Baker f. * ''Chrysoscias'' E.

Soil Improvers
Soil, also commonly referred to as earth or dirt, is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life. Some scientific definitions distinguish ''dirt'' from ''soil'' by restricting the former term specifically to displaced soil. Soil consists of a solid phase of minerals and organic matter (the soil matrix), as well as a porous phase that holds gases (the soil atmosphere) and water (the soil solution). Accordingly, soil is a three-state system of solids, liquids, and gases. Soil is a product of several factors: the influence of climate, relief (elevation, orientation, and slope of terrain), organisms, and the soil's parent materials (original minerals) interacting over time. It continually undergoes development by way of numerous physical, chemical and biological processes, which include weathering with associated erosion. Given its complexity and strong internal connectedness, soil ecologists regard soil as an ecosystem. Most so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
