Santa Cruz Water-lily
''Victoria cruziana'' (Santa Cruz water lily, water platter, yrupe, synonym ''Victoria argentina'' Burmeist.) is a tropical species of flowering plant, of the Nymphaeaceae family of water lilies native to South America, primarily Bolivia, Argentina and Paraguay. The plant is a popular water garden plant in botanical gardens where its very large leaves can reach their fullest, up to 2 m wide with a thick rim up to 20 cm high. although rims up to nine inches (23 centimeters) have been recorded. It can be grown in cooler waters than its sister within the genus, the more familiar giant waterlily, ''Victoria amazonica''. A 25 cm diameter flower blooms for two days, arising from the underwater bud, as a white flower that turns to a deep pink on the second and final day of its bloom. ''V. cruziana'' is a thermogenetic or heat-producing plant. The plant prefers to live in colder non moving water and requires warm temperatures in order for the flower to blossom, hence the plant m ...

Alcide D'Orbigny
Alcide Charles Victor Marie Dessalines d'Orbigny (6 September 1802 – 30 June 1857) was a French naturalist who made major contributions in many areas, including zoology (including malacology), palaeontology, geology, archaeology and anthropology. D'Orbigny was born in Couëron ( Loire-Atlantique), the son of a ship's physician and amateur naturalist. The family moved to La Rochelle in 1820, where his interest in natural history was developed while studying the marine fauna and especially the microscopic creatures that he named "foraminiferans". In Paris he became a disciple of the geologist Pierre Louis Antoine Cordier (1777–1861) and Georges Cuvier. All his life, he would follow the theory of Cuvier and stay opposed to Lamarckism. South American era D'Orbigny travelled on a mission for the Paris Museum, in South America between 1826 and 1833. He visited Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, Argentina, Paraguay, and Brazil, and returned to France with an ...

Hermann Carl Conrad Burmeister
Karl Hermann Konrad Burmeister (also known as Carlos Germán Conrado Burmeister) (15 January 1807 – 2 May 1892) was a German Argentine zoologist, entomologist, herpetologist, botanist, and coleopterologist. He served as a professor at the University of Halle, headed the museum there and published the ''Handbuch der Entomologie'' (1832–1855) before moving to Argentina where he worked until his death. Career Burmeister was born in Stralsund, where his father was a customs officer. He studied medicine at Greifswald (1825–1827) and Halle (1827–1829), and in 1830 went to Berlin to qualify himself to be a teacher of natural history. His dissertation was titled ''De insectorum systemate naturali'' and graduated as a doctor of medicine on November 4, 1829 and then received a doctor of philosophy on December 19 in the same year. He then joined for military service in Berlin and Grünberg (Silesia). He was soon after appointed an instructor in the gymnasium at Cologne. He lat ...

Nymphaeaceae
Nymphaeaceae () is a family of flowering plants, commonly called water lilies. They live as rhizomatous aquatic herbs in temperate and tropical climates around the world. The family contains nine genera with about 70 known species. Water lilies are rooted in soil in bodies of water, with leaves and flowers floating on or emergent from the surface. Leaves are round, with a radial notch in '' Nymphaea'' and ''Nuphar'', but fully circular in ''Victoria'' and ''Euryale''. Water lilies are a well-studied clade of plants because their large flowers with multiple unspecialized parts were initially considered to represent the floral pattern of the earliest flowering plants, and later genetic studies confirmed their evolutionary position as basal angiosperms. Analyses of floral morphology and molecular characteristics and comparisons with a sister taxon, the family Cabombaceae, indicate, however, that the flowers of extant water lilies with the most floral parts are more derived ...

South America
South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere at the northern tip of the continent. It can also be described as the southern subregion of a single continent called America. South America is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean; North America and the Caribbean Sea lie to the northwest. The continent generally includes twelve sovereign states: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela; two dependent territories: the Falkland Islands and South Georgia and the South Sandwich Islands; and one internal territory: French Guiana. In addition, the ABC islands of the Kingdom of the Netherlands, Ascension Island (dependency of Saint Helena, Ascension and Tristan da Cunha, a British Overseas Territory), Bouvet Island ( dependency of Norway), Pa ...

Argentina
Argentina (), officially the Argentine Republic ( es, link=no, República Argentina), is a country in the southern half of South America. Argentina covers an area of , making it the second-largest country in South America after Brazil, the fourth-largest country in the Americas, and the eighth-largest country in the world. It shares the bulk of the Southern Cone with Chile to the west, and is also bordered by Bolivia and Paraguay to the north, Brazil to the northeast, Uruguay and the South Atlantic Ocean to the east, and the Drake Passage to the south. Argentina is a federal state subdivided into twenty-three provinces, and one autonomous city, which is the federal capital and largest city of the nation, Buenos Aires. The provinces and the capital have their own constitutions, but exist under a federal system. Argentina claims sovereignty over the Falkland Islands, South Georgia and the South Sandwich Islands, and a part of Antarctica. The earliest recorded human prese ...

Paraguay
Paraguay (; ), officially the Republic of Paraguay ( es, República del Paraguay, links=no; gn, Tavakuairetã Paraguái, links=si), is a landlocked country in South America. It is bordered by Argentina to the south and southwest, Brazil to the east and northeast, and Bolivia to the northwest. It has a population of seven million, nearly three million of whom live in the capital and largest city of Asunción, and its surrounding metro. Although one of only two landlocked countries in South America (Bolivia is the other), Paraguay has ports on the Paraguay and Paraná rivers that give exit to the Atlantic Ocean, through the Paraná-Paraguay Waterway. Spanish conquistadores arrived in 1524, and in 1537, they established the city of Asunción, the first capital of the Governorate of the Río de la Plata. During the 17th century, Paraguay was the center of Jesuit missions, where the native Guaraní people were converted to Christianity and introduced to European culture. ...

Victoria Amazonica
''Victoria amazonica'' is a species of flowering plant, the second largest of the water lily family Nymphaeaceae. It is the national flower of Guyana. Its native regions are Guyana and tropical South America. Description The ''Victoria amazonica'' has very large leaves, up to in diameter, that float on the water's surface on a submerged stalk, in length, rivaling that of the green anaconda, a snake local to its habitat. It is the second-largest waterlily in the world. ''V. amazonica'' is native to the shallow waters of the Amazon River basin, such as oxbow lakes and bayous. In their native habitat, the flowers first begin to open as the sun starts to set and can take up to 48 hours to fully open. These flowers can grow up to 40 cm (16 in) in diameter. Each plant continues to produce flowers for a full growing season, and they have co-evolved a mutualistic relationship with a species of scarab beetle of the genus '' Cyclocephala'' as a pollinator.

Thermogenesis
Thermogenesis is the process of heat production in organisms. It occurs in all warm-blooded animals, and also in a few species of thermogenic plants such as the Eastern skunk cabbage, the Voodoo lily (''Sauromatum venosum''), and the giant water lilies of the genus ''Victoria''. The lodgepole pine dwarf mistletoe, ''Arceuthobium americanum'', disperses its seeds explosively through thermogenesis.Rolena A.J. deBruyn, Mark Paetkau, Kelly A. Ross, David V. Godfrey & Cynthia Ross Friedman (2015)"Thermogenesis-triggered seed dispersal in dwarf mistletoe" Types Depending on whether or not they are initiated through locomotion and intentional movement of the muscles, thermogenic processes can be classified as one of the following: * Exercise-associated thermogenesis (EAT) * Non-exercise activity thermogenesis (NEAT), energy expended for everything that is not sleeping, eating or sports-like exercise. * Diet-induced thermogenesis (DIT) Shivering One method to raise temperature is thr ...

Stigma (botany)
The stigma () is the receptive tip of a carpel, or of several fused carpels, in the gynoecium of a flower. Description The stigma, together with the style and ovary (typically called the stigma-style-ovary system) comprises the pistil, which is part of the gynoecium or female reproductive organ of a plant. The stigma itself forms the distal portion of the style, or stylodia, and is composed of , the cells of which are receptive to pollen. These may be restricted to the apex of the style or, especially in wind pollinated species, cover a wide surface. The stigma receives pollen and it is on the stigma that the pollen grain germinates. Often sticky, the stigma is adapted in various ways to catch and trap pollen with various hairs, flaps, or sculpturings. The pollen may be captured from the air (wind-borne pollen, anemophily), from visiting insects or other animals ( biotic pollination), or in rare cases from surrounding water (hydrophily). Stigma can vary from long and sle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Andrés De Santa Cruz
Andrés de Santa Cruz y Calahumana (; 30 November 1792 – 25 September 1865) was a Bolivian general and politician who served as interim president of Peru in 1827, the interim president of Peru from 1836 to 1838 and the sixth president of Bolivia from 1829 to 1839. He also served as Supreme Protector of the short-lived Peru-Bolivian Confederation from 1836 to 1839, a political entity created mainly by his personal endeavors. Early life and education Santa Cruz was born on 30 November 1792, in the town of Huarina, La Paz. His father was José Santa Cruz y Villavicencio, a Spaniard, and his mother Juana Basilia Calahumana, an Amerindian and ''cacique'' of the town of Huarina. In later years, Andrés de Santa Cruz would claim that through his mother, he descended directly from Inca rulers. He began his studies in his hometown at the San Francisco Convent, and continued them at the San Antonio Abad Seminary in the city of Cuzco. In 1809 he left the seminary and returned to La ...
