Ziziphus Nummularia
''Ziziphus nummularia'', commonly known as wild jujube or jhahrberi in Hindi, is a species of ''Ziziphus'' native to the Thar Desert of western India and southeastern Pakistan, south Iran, Afghanistan, Lebanon and Zimbabwe. ''Ziziphus nummularia'' is a shrub up to or more high, branching to form a thicket. The leaves are rounded like those of ''Ziziphus jujuba'' but differ from those in having a pubescence on the adaxial surface. The plant is commonly found in arid areas, hills, plains, and agricultural fields. Description ''Ziziphus nummularia'' is a much-branched, widely-spreading, thorny bush or shrub up to tall. The branches and twigs have a velvety texture and a pale purplish colour. The lateral roots are long and spread deeply into the substrate. The alternately arranged leaves are simple and ovate, long, with serrate margins; the upper surface of the blade is dark green and glossy, and the under surface is white and downy. The stipules are often replaced by a pair o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Syzygium Hyrianium
''Syzygium'' () is a genus of flowering plants that belongs to the myrtle family, Myrtaceae. The genus comprises about 1200 species, and has a native range that extends from Africa and Madagascar through southern Asia east through the Pacific. Its highest levels of diversity occur from Malaysia to northeastern Australia, where many species are very poorly known and many more have not been described taxonomically. Most species are evergreen trees and shrubs. Several species are grown as ornamental plants for their attractive glossy foliage, and a few produce edible fruits that are eaten fresh or used in jams and jellies. The most economically important species, however, is the clove ''Syzygium aromaticum'', of which the unopened flower buds are an important spice. Some of the edible species of ''Syzygium'' are planted throughout the tropics worldwide, and several have become invasive species in some island ecosystems. Several species of ''Syzygium'' bear fruits that are edible for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Qatar
The flora of Qatar includes more than 300 species of wild plants. Qatar occupies a small desert peninsula that is around 80 km (50 miles) from east to west and 160 km (100 miles) from north to south. The climate is hot and humid with sporadic rain. Majority of the country is flat with an annual rainfall average of less than 3 inches. Arnebia hispidissim blooms yellow flowers annually in sandy soil. Glossonema edule has edible fruits with brownish-yellow flowers. Vegetation is extremely sparse in the hamada landscape due to the heavily weathered soil. A native species of tree, ''Vachellia tortilis'' (known locally as ''samr'') is well adapted to the desert environment and one of the most common forms of vegetation in the country. '' Tetraena qatarensis'' and ''Lycium shawii'' also grow in this landscape.Casey & Vine (1992), p. 78 Shallow depressions referred to as ''rawdat'' constitute a more varied selection of plants since rainwater run-off is more likely to accumulate.

Flora Of Iran
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of India (region)
The flora of India is one of the richest in the world due to the wide range of climate, topology and habitat in the country. There are estimated to be over 18,000 species of flowering plants in India, which constitute some 6-7 percent of the total plant species in the world. India is home to more than 50,000 species of plants, including a variety of endemics. The use of plants as a source of medicines has been an integral part of life in India from the earliest times. There are more than 3000 Indian plant species officially documented as possessing into eight main floristic regions : Western Himalayas, Eastern Himalayas, Assam, Indus plain, Ganges plain, the Deccan, Malabar and the Andaman Islands. Forests and wildlife resources In 1992, around 7,43,534 km2 of land in the country was under forests of which 92 percent belongs to the government. Only 22.7 percent is forested compared to the recommended 33 percent of the National Forest Policy Resolution 1952. The majo ...

Gerbil
The Mongolian gerbil or Mongolian jird (''Meriones unguiculatus'') is a small rodent belonging to the subfamily Gerbillinae. Their body size is typically , with a tail, and body weight , with adult males larger than females. The animal is used in science and kept as a small house pet. Their use in science dates back to the latter half of the 19th century, but they only started to be kept as pets in the English-speaking world after 1954, when they were brought to the United States. However, their use in scientific research has fallen out of favor. Habitat Mongolian gerbils inhabit grassland, shrubland and desert, including semidesert and steppes in China, Mongolia, and the Russian Federation. Soil on the steppes is sandy and is covered with grasses, herbs, and shrubs. The steppes have cool, dry winters and hot summers. The temperature can get up to , but the average temperature for most of the year is around . In the wild, these gerbils live in patriarchal groups generally ...

Charcoal
Charcoal is a lightweight black carbon residue produced by strongly heating wood (or other animal and plant materials) in minimal oxygen to remove all water and volatile constituents. In the traditional version of this pyrolysis process, called charcoal burning, often by forming a charcoal kiln, the heat is supplied by burning part of the starting material itself, with a limited supply of oxygen. The material can also be heated in a closed retort. Modern "charcoal" briquettes used for outdoor cooking may contain many other additives, e.g. coal. This process happens naturally when combustion is incomplete, and is sometimes used in radiocarbon dating. It also happens inadvertently while burning wood, as in a fireplace or wood stove. The visible flame in these is due to combustion of the volatile gases exuded as the wood turns into charcoal. The soot and smoke commonly given off by wood fires result from incomplete combustion of those volatiles. Charcoal burns at a higher temper ...

Poaceae
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of biofuel, ...

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
