Tephrosia Apollinea
''Tephrosia apollinea'' is a legume species, native to southwest Asia (the Levant, Arabian Peninsula, Socotra, Iran, Pakistan, northwestern India) and northeast Africa (Egypt, Sudan, Ethiopia, Eritrea, Djibouti, Somalia). The leaflets of the plant are obovate-oblong and equal-sided, and of a silky texture. The fruits ( legumes) are typically long and contain six or seven brownish seeds. The species typically grows in areas where the soils are relatively deep, especially in semi-arid and wadi areas, and on terraces and slight inclines and hills. ''Tephrosia apollinea'' is known to be toxic to goats. Although it has been used in Oman and the United Arab Emirates to treat bronchitis, cough, earache, nasal congestion and wounds and bone fractures, as of 1993 its wider impact on humans had not been assessed. It can be used to make indigo-like dyes, and the leaves and those of other plants are used to make hot drinks by the Bedouin in parts of Sinai and the Negev. Description Th ...

Alire Raffeneau Delile
Alire Raffeneau Delile (23 January 1778, in Versailles – 5 July 1850, in Montpellier) was a French botanist. Biography Delile studied botany with Jean Lemonnier, and was in the Paris medical school in 1796. Egypt Delile participated in Napoleon Bonaparte's Egypt Campaign where he described Lotus and Papyrus. Director of the Cairo botanical garden, he wrote the botanical sections of ''Travel in Lower and Upper Egypt'' by Dominique Vivant. He made a cast of the Rosetta Stone which allowed the reproduction of its Greek and Demotic inscriptions in his ''Description de l'Égypte''. United States In 1802, Delile was appointed French vice consul at Wilmington, North Carolina, and also asked to form an herbarium of all American plants that could be naturalized in France. He sent to Paris several cases of seeds and grains, and discovered some new graminea and presented them to Palisot de Beauvois, who described them in his ''Agrostographie''. Raffeneau made extensive explorations thr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chromosome
A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are the histones. These proteins, aided by chaperone proteins, bind to and condense the DNA molecule to maintain its integrity. These chromosomes display a complex three-dimensional structure, which plays a significant role in transcriptional regulation. Chromosomes are normally visible under a light microscope only during the metaphase of cell division (where all chromosomes are aligned in the center of the cell in their condensed form). Before this happens, each chromosome is duplicated ( S phase), and both copies are joined by a centromere, resulting either in an X-shaped structure (pictured above), if the centromere is located equatorially, or a two-arm structure, if the centromere is located distally. The joined copies are now c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Astragalus Spinosus
''Astragalus'' is a large genus of over 3,000 species of herbs and small shrubs, belonging to the legume family Fabaceae and the subfamily Faboideae. It is the largest genus of plants in terms of described species. The genus is native to temperate regions of the Northern Hemisphere. Common names include milkvetch (most species), locoweed (in North America, some species) and goat's-thorn ( ''A. gummifer'', ''A. tragacantha''). Some pale-flowered vetches (''Vicia'' spp.) are similar in appearance, but they are more vine-like than ''Astragalus''. Description Most species in the genus have pinnately compound leaves. There are annual and perennial species. The flowers are formed in clusters in a raceme, each flower typical of the legume family, with three types of petals: banner, wings, and keel. The calyx is tubular or bell-shaped. Ecology ''Astragalus'' species are used as food plants by the larvae of some Lepidoptera species including many case-bearing moths of the ge ...

Rhanterium Epapposum
''Rhanterium epapposum'' is a plant of the family Asteraceae. Native to the deserts of the Arabian Peninsula including Saudi Arabia, Kuwait and Qatar where it is known locally as ''arfaj'' (). The ''arfaj'' consists of a complicated network of branches scattered with small thorny leaves and bright yellow flowers about 1.5 cm wide. The ''arfaj'' flower is also the national flower of Kuwait. It is a bushy shrub approximately 80 cm height. The leaves are small and narrow, and in late spring it will start flowering (April–May). It is considered one of the main desert forage plants for camels and sheep. When cold temperature prevails the plant produces leaves quickly after rainfall. In a few months, the branches and newly formed leaves become vigorous, and the yellow flowers are produced, attracting insects and birds. In the summer, when the earth has dried out, the leaves fall and the branches become naked and lignified with living fibers. In times of stress, these alter ...

Forb
A forb or phorb is an herbaceous flowering plant that is not a graminoid (grass, sedge, or rush). The term is used in biology and in vegetation ecology, especially in relation to grasslands and understory. Typically these are dicots without woody stems. Etymology The word "forb" is derived from Greek ''phorbḗ'' (), meaning "pasture" or "fodder". The Hellenic spelling "phorb" is sometimes used, and in older usage this sometimes includes graminids and other plants currently not regarded as forbs. Guilds Forbs are members of a guilda group of plant species with broadly similar growth form. In certain contexts in ecology, guild membership may often be more important than the taxonomic relationships between organisms. In informal classification In addition to its use in ecology, the term "forb" may be used for subdividing popular guides to wildflowers, distinguishing them from other categories such as grasses, sedges, shrubs, and trees. Some examples of forbs are clovers, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Desert
A desert is a barren area of landscape where little precipitation occurs and, consequently, living conditions are hostile for plant and animal life. The lack of vegetation exposes the unprotected surface of the ground to denudation. About one-third of the land surface of the Earth is arid or semi-arid. This includes much of the polar regions, where little precipitation occurs, and which are sometimes called polar deserts or "cold deserts". Deserts can be classified by the amount of precipitation that falls, by the temperature that prevails, by the causes of desertification or by their geographical location. Deserts are formed by weathering processes as large variations in temperature between day and night put strains on the rocks, which consequently break in pieces. Although rain seldom occurs in deserts, there are occasional downpours that can result in flash floods. Rain falling on hot rocks can cause them to shatter, and the resulting fragments and rubble strewn over t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fujeirah North 1501200713146 Tephrosia Apollinea
The Emirate of Fujairah ( ar, إِمَـارَة ٱلْفُجَيْرَة ' ) is one of the seven emirates that make up the United Arab Emirates. The only of the seven with a coastline solely on the Gulf of Oman and none on the Persian Gulf, its capital is Fujairah. History The Emirate of Fujairah, dominated by the ''Sharqiyin'' tribe, sits at the mouth of the important trade route, the ''Wadi Ham'' (which is guarded by the Sharqiyin Al Bithnah Fort), through the mountains to the interior and the Persian Gulf Coast. Known as the ''Shamaliyah'', the east coast of what is now the UAE was subject to Muscat until 1850, when it was annexed by ''Al Qasimi'' of Sharjah, in an agreement made between Sheikh Sultan bin Saqr Al Qasimi and the Sultan of Muscat. The Shamaliyah was governed by Al-Qasimi Wali at Kalba although frequently seceded and in 1901 Sheikh Hamad bin Abdullah Al Sharqi, chief of the Sharqiyin, declared independence from Sharjah. This was recognized by a number ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Plant List
The Plant List was a list of botanical names of species of plants created by the Royal Botanic Gardens, Kew and the Missouri Botanical Garden and launched in 2010. It was intended to be a comprehensive record of all known names of plant species over time, and was produced in response to Target 1 of the 2002-2010 Global Strategy for Plant Conservation (GSP C), to produce "An online flora of all known plants.” It has not been updated since 2013, and has been superseded by World Flora Online. World Flora Online In October 2012, the follow-up project World Flora Online was launched with the aim to publish an online flora of all known plants by 2020. This is a project of the United Nations Convention on Biological Diversity, with the aim of halting the loss of plant species worldwide by 2020. It is developed by a collaborative group of institutions around the world response to the 2011-2020 GSPC's updated Target 1. This aims to achieve an online Flora of all known plants by 202 ...

Eastern Desert
The Eastern Desert (Archaically known as Arabia or the Arabian Desert) is the part of the Sahara desert that is located east of the Nile river. It spans of North-Eastern Africa and is bordered by the Nile river to the west and the Red Sea and Gulf of Suez to the east. It extends through Egypt, Eritrea, Sudan and Ethiopia. The Eastern Desert is also known as the Red Sea Hills. The Desert consists of a mountain range which runs parallel to the coast, wide sedimentary plateaus extending from either side of the mountains and the Red Sea coast. The rainfall, climate, vegetation and animal life sustained in the desert varies between these different regions.The Desert has been a mining site for building materials, and precious and semi-precious metals throughout history. It has historically contained many trade routes leading to and from the Red Sea, including the Suez Canal.

Periderm
Bark is the outermost layers of stems and roots of woody plants. Plants with bark include trees, woody vines, and shrubs. Bark refers to all the tissues outside the vascular cambium and is a nontechnical term. It overlays the wood and consists of the inner bark and the outer bark. The inner bark, which in older stems is living tissue, includes the innermost layer of the periderm. The outer bark on older stems includes the dead tissue on the surface of the stems, along with parts of the outermost periderm and all the tissues on the outer side of the periderm. The outer bark on trees which lies external to the living periderm is also called the rhytidome. Products derived from bark include bark shingle siding and wall coverings, spices and other flavorings, tanbark for tannin, resin, latex, medicines, poisons, various hallucinogenic chemicals and cork. Bark has been used to make cloth, canoes, and ropes and used as a surface for paintings and map making. A number of plants are ...
