Sparganium
''Sparganium'' (bur-reed) is a genus of flowering plants, described as a genus by Linnaeus in 1753. It is widespread in wet areas in temperate regions of both the Northern and Southern Hemispheres. The plants are perennial marsh plants that can grow to 3.5 m (depending on the species), with epicene flowers. It was previously placed alone in the family Sparganiaceae. ''Sparganium'' is closely related to the Typhaceae and the APG III system (2009) includes ''Sparganium'' in that family. It has been determined from phylogenetic analysis to be the closest living relative of the genus '' Typha'' (cat-tail). Summary ''Sparganium'', commonly known as the bur-reed, is a genus of aquatic plants of shallow marshes, ponds and streams. There are 9 species found in the United States and Canada. The stem, which may be floating or emergent, emerges from a buried rhizome, which like many wetland plants, is dependent upon aerenchyma to transport oxygen to the rooting zone. The leaves are st ...

Flutes
The flute is a family of classical music instrument in the woodwind group. Like all woodwinds, flutes are aerophones, meaning they make sound by vibrating a column of air. However, unlike woodwind instruments with reeds, a flute is a reedless wind instrument that produces its sound from the flow of air across an opening. According to the instrument classification of Hornbostel–Sachs, flutes are categorized as edge-blown aerophones. A musician who plays the flute is called a flautist or flutist. Flutes are the earliest known identifiable musical instruments, as paleolithic examples with hand-bored holes have been found. A number of flutes dating to about 53,000 to 45,000 years ago have been found in the Swabian Jura region of present-day Germany. These flutes demonstrate that a developed musical tradition existed from the earliest period of modern human presence in Europe..

Ancient Greece
Ancient Greece ( el, Ἑλλάς, Hellás) was a northeastern Mediterranean civilization, existing from the Greek Dark Ages of the 12th–9th centuries BC to the end of classical antiquity ( AD 600), that comprised a loose collection of culturally and linguistically related city-states and other territories. Most of these regions were officially unified only once, for 13 years, under Alexander the Great's empire from 336 to 323 BC (though this excludes a number of Greek city-states free from Alexander's jurisdiction in the western Mediterranean, around the Black Sea, Cyprus, and Cyrenaica). In Western history, the era of classical antiquity was immediately followed by the Early Middle Ages and the Byzantine period. Roughly three centuries after the Late Bronze Age collapse of Mycenaean Greece, Greek urban poleis began to form in the 8th century BC, ushering in the Archaic period and the colonization of the Mediterranean Basin. This was followed by the age of Classical G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wheat
Wheat is a grass widely cultivated for its seed, a cereal grain that is a worldwide staple food. The many species of wheat together make up the genus ''Triticum'' ; the most widely grown is common wheat (''T. aestivum''). The archaeological record suggests that wheat was first cultivated in the regions of the Fertile Crescent around 9600 BCE. Botanically, the wheat kernel is a type of fruit called a caryopsis. Wheat is grown on more land area than any other food crop (, 2014). World trade in wheat is greater than for all other crops combined. In 2020, world production of wheat was , making it the second most-produced cereal after maize. Since 1960, world production of wheat and other grain crops has tripled and is expected to grow further through the middle of the 21st century. Global demand for wheat is increasing due to the unique viscoelastic and adhesive properties of gluten proteins, which facilitate the production of processed foods, whose consumption is inc ...

United Kingdom
The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a country in Europe, off the north-western coast of the continental mainland. It comprises England, Scotland, Wales and Northern Ireland. The United Kingdom includes the island of Great Britain, the north-eastern part of the island of Ireland, and many smaller islands within the British Isles. Northern Ireland shares a land border with the Republic of Ireland; otherwise, the United Kingdom is surrounded by the Atlantic Ocean, the North Sea, the English Channel, the Celtic Sea and the Irish Sea. The total area of the United Kingdom is , with an estimated 2020 population of more than 67 million people. The United Kingdom has evolved from a series of annexations, unions and separations of constituent countries over several hundred years. The Treaty of Union between the Kingdom of England (which included Wales, annexed in 1542) and the Kingdom of Scotland in 170 ...

Thatching
Thatching is the craft of building a roof with dry vegetation such as straw, water reed, sedge (''Cladium mariscus''), rushes, heather, or palm branches, layering the vegetation so as to shed water away from the inner roof. Since the bulk of the vegetation stays dry and is densely packed—trapping air—thatching also functions as insulation. It is a very old roofing method and has been used in both tropical and temperate climates. Thatch is still employed by builders in developing countries, usually with low-cost local vegetation. By contrast, in some developed countries it is the choice of some affluent people who desire a rustic look for their home, would like a more ecologically friendly roof, or who have purchased an originally thatched abode. History Thatching methods have traditionally been passed down from generation to generation, and numerous descriptions of the materials and methods used in Europe over the past three centuries survive in archives and early publica ...

Common Reed
''Phragmites australis'', known as the common reed, is a species of plant. It is a broadly distributed wetland grass that can grow up to tall. Description ''Phragmites australis'' commonly forms extensive stands (known as reed beds), which may be as much as or more in extent. Where conditions are suitable it can also spread at or more per year by horizontal runners, which put down roots at regular intervals. It can grow in damp ground, in standing water up to or so deep, or even as a floating mat. The erect stems grow to tall, with the tallest plants growing in areas with hot summers and fertile growing conditions. The leaves are long and broad. The flowers are produced in late summer in a dense, dark purple panicle, about long. Later the numerous long, narrow, sharp pointed spikelets appear greyer due to the growth of long, silky hairs. These eventually help disperse the minute seeds. Taxonomy Recent studies have characterized morphological distinctions between the int ...

Marsh Arabs
The Marsh Arabs ( ar, عرب الأهوار ''ʻArab al-Ahwār'' "Arabs of the Marshlands"), also referred to as the Maʻdān ( ar, معدان "dweller in the plains") or Shroog (Iraqi ar, شروق, "those from the east")—the latter two often considered derogatory in the present day—are Arabian inhabitants of the Mesopotamian marshlands in the modern-day south Iraq, as well as in the Hawizeh Marshes straddling the Iraq-Iran border. Comprising members of many different tribes and tribal confederations, such as the Āl Bū Muḥammad, Ferayghāt, Shaghanbah, the Maʻdān had developed a culture centered on the marshes' natural resources and unique from other Arabs. Many of the marshes' inhabitants were displaced when the wetlands were drained during and after the 1991 uprisings in Iraq. The draining of the marshes caused a significant decline in bioproductivity; following the Multi-National Force overthrow of the Saddam Hussein regime, water flow to the marshes was restore ...

Thamnochortus Insignis
''Thamnochortus insignis'' is a species of grass-like restio of the family Restionaceae, endemic to Cape Province in South Africa. Appearance Plants are tall, grass- or reed-like tussocks with a diameter of 500 mm to 1 metre at the base and a spread of 3 metres or more at the top and up to 2,5 m tall. Male and female plants are separate and very similar when they are not flowering. Range ''Thamnochortus insignis'' grows in dense stands in the southern Cape around Albertinia. It can now be found along the roadsides from Port Elizabeth to the Cedarberg, where the seed has been distributed by the trucks carrying the thatching material. Propagation The plants are wind pollinated with the male inflorescences in small tassels swaying in the wind, while the female flowers are at the base of medium sized bracts, which catch the pollen from the air and funnel it towards the small fringed styles of the female flowers. The seed comes in the form of a tiny nutlet inside the o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
