Jiddat Al-Harasis
Jiddat al-Harasis (Jiddat-il-Harasiis) is a stony desert in south-central Oman, separating northern Oman from Dhufar. The largest strewn field of meteorites in the country is situated here. Over 160 bird species, including the endangered houbara bustard, are found here, as well as Arabian oryx and Arabian gazelle. The area was not permanently inhabited until the 19th century with the arrival of the Harasis. Geography Jiddat al-Harasis covers an area of about in an elevation range of . The area is delimited by an escarpment of height on the east with the Huquf depression adjoining it. This area is hemmed between the Arabian Sea and the Janabah Hills, which rise to a height of . The Arabian Sea forms Jiddat's eastern and southern borders. The geology is predominantly Miocene karst limestone. Older geological features include 300 million year old glacial pavements which are well preserved given their age. Climate The Southwest Monsoon and coastal fog both occur at Jiddat al-H ...

Zygophyllum
''Zygophyllum'' is the type genus of the flowering plant family Zygophyllaceae. The generic name is derived from the Greek words ζυγόν (''zygon''), meaning "double", and φυλλον (''phyllon''), meaning "leaf". It refers to the leaves, each of which have two leaflets. The genus is distributed in arid and semi-arid regions of Africa, the Mediterranean Basin, central Asia and Australia. Molecular phylogenetic analysis suggested that as previously circumscribed, ''Zygophyllum'' was not monophyletic, and the genus was split among a number of other genera, including '' Augea'', ''Fagonia'', ''Roepera'' and '' Tetraena''. Species In accordance with International Plant Names Index, genus ''Zygophyllum'' currently has 117 accepted species: *''Zygophyllum acerosum'' (Boiss.)

Lycium Shawii
''Lycium shawii'', desert thorn or Arabian boxthorn is a species of thorny shrub adapted to desert environments, and can be found throughout the Arabian peninsula, and some places in Africa. The thin leaved, rigid bush grows up to high, with a lot of branches and alternating spines that vary in size, and grow along the branches and on their tips. The leaves narrow towards their base. It produces small whitish-pink or purple flowers from September until April, and red pea-sized seedy berries that are edible. Habitats include gravel plains and foothills up to , as well as wadis. Plants often growing nearby include ''Acacia tortilis'' and ''Prosopis cineraria''. Uses The stems, leaves and berries are used in traditional medicine. In Yemen, the pounded leaves of this shrub have been used as a cure for eye ailments. The berries have a laxative effect and were used in traditional medicine to relieve constipation and as a diuretic. Livestock eat new growth on the plant.

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''Ochradenus'' is a genus of plant in family Resedaceae. It contains the following species (but this list may be incomplete): * ''Ochradenus socotranus'', * ''Ochradenus baccatus ''Ochradenus'' is a genus of plant in family Resedaceae Resedaceae is a family of mostly herbaceous dicotyledonous plants comprising 107 known species in 8 to 12 genera: *''Borthwickia'' - 1 species, sometimes placed in its own family Borthwic ...'' A recent molecular study found that ''Ochradenus'' arose from within the ranks of '' Reseda''. Therefore, in future this genus may be abandoned, and its species transferred into ''Reseda''.

Crotalaria Aegyptiaca
''Crotalaria'' is a genus of flowering plants in the family Fabaceae (subfamily Faboideae) commonly known as rattlepods. The genus includes over 700 species of herbaceous plants and shrubs. Africa is the continent with the majority of ''Crotalaria'' species (approximately 400 species), which are mainly found in damp grassland, especially in floodplains, depressions and along edges of swamps and rivers, but also in deciduous bush land, roadsides and fields. Some species of ''Crotalaria'' are grown as ornamentals. The common name rattlepod or rattlebox is derived from the fact that the seeds become loose in the pod as they mature, and rattle when the pod is shaken. The name derives from the Ancient Greek , meaning "castanet", and is the same root as the name for the rattlesnakes (''Crotalus''). ''Crotalaria'' species are used as food plants by the larvae of some Lepidoptera species including ''Endoclita sericeus'', ''Etiella zinckenella'' and ''Utetheisa ornatrix''. The toxic alkalo ...

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 ...

Prosopis Cineraria
''Prosopis cineraria'', also known as ghaf, is a species of flowering tree in the pea family, Fabaceae. It is native to arid portions of Western Asia and the Indian Subcontinent, including Afghanistan, Bahrain, Iran, India, Oman, Pakistan, Saudi Arabia, the United Arab Emirates and Yemen. Its leaves are shattered and stripy along its branch. It can survive extreme drought. It is an established introduced species in parts of Southeast Asia, including Indonesia. The ʿGhaf is the national tree of the United Arab Emirates. Through the ''Give a Ghaf campaign'' its citizens are urged to plant it in their gardens to combat desertification and to preserve their country's heritage. The desert village of Nazwa in the UAE is home to the Al Ghaf Conservation Reserve. ''Prosopis cineraria'' is also the state tree of Rajasthan (where it is known as Khejri), Western Uttar Pradesh (where it is known as Chhonkara) and Telangana (where it is known as ''Jammi'' ) in India.

The seeds pods are flattened and curved with constrictions between the seeds. This shrub resembles the red acacia (''Vachellia seyal'') but that species lives in habitats with higher precipitation and has thorns that are shorter than its leaves. It ...

Acacia Tortilis
''Vachellia tortilis'', widely known as ''Acacia tortilis'' but now attributed to the genus ''Vachellia'', is the umbrella thorn acacia, also known as ''umbrella thorn'' and Israeli babool, a medium to large canopied tree native to most of Africa, primarily to the savanna and Sahel of Africa (especially the Somali peninsula and Sudan), but also occurring in the Middle East. Distribution and growing conditions ''Vachellia tortilis'' is widespread in Africa, being found in countries like Tunisa, Morocco, Uganda, Angola, Zimbabwe, Djibouti, and Botswana. It tends to grow in areas where temperatures vary from and rainfall is anywhere from about per year. Characteristics In extremely arid conditions, it may occur as a small, wiry bush.
