Oedera Uniflora
''Oedera uniflora'' ("Kalksteenperdekaroo") is a prickly shrublet belonging to the family Asteraceae. Description ''Oedera uniflora'' is a small shrublet, with extremely sticky leaves, arranged in four clear ranks. Each leaf has a tip that is slightly hooked downwards, and a clear basal abscission line. The yellow flowerheads are usually solitary, and appear at the tips of the branches in Spring and Summer.

Asteraceae
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more technicall ...

Decussation
Decussation is used in biological contexts to describe a crossing (due to the shape of the Roman numeral for ten, an uppercase 'X' (), ). In Latin anatomical terms, the form is used, e.g. . Similarly, the anatomical term chiasma is named after the Greek uppercase 'Χ' (chi). Whereas a decussation refers to a crossing within the central nervous system, various kinds of crossings in the peripheral nervous system are called chiasma. Examples include: * In the brain, where nerve fibers obliquely cross from one lateral side of the brain to the other, that is to say they cross at a level other than their origin. See for examples Decussation of pyramids and sensory decussation. In neuroanatomy, the term ''chiasma'' is reserved for crossing of- or within nerves such as in the optic chiasm. * In botanical leaf taxology, the word ''decussate'' describes an opposite pattern of leaves which has successive pairs at right angles to each other (i.e. rotated 90 degrees along the stem when ...

Western Cape Province
The Western Cape is a province of South Africa, situated on the south-western coast of the country. It is the fourth largest of the nine provinces with an area of , and the third most populous, with an estimated 7 million inhabitants in 2020. About two-thirds of these inhabitants live in the metropolitan area of Cape Town, which is also the provincial capital. The Western Cape was created in 1994 from part of the former Cape Province. The two largest cities are Cape Town and George. Geography The Western Cape Province is roughly L-shaped, extending north and east from the Cape of Good Hope, in the southwestern corner of South Africa. It stretches about northwards along the Atlantic coast and about eastwards along the South African south coast (Southern Indian Ocean). It is bordered on the north by the Northern Cape and on the east by the Eastern Cape. The total land area of the province is , about 10.6% of the country's total. It is roughly the size of England or the St ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Africa
South Africa, officially the Republic of South Africa (RSA), is the southernmost country in Africa. It is bounded to the south by of coastline that stretch along the South Atlantic and Indian Oceans; to the north by the neighbouring countries of Namibia, Botswana, and Zimbabwe; and to the east and northeast by Mozambique and Eswatini. It also completely enclaves the country Lesotho. It is the southernmost country on the mainland of the Old World, and the second-most populous country located entirely south of the equator, after Tanzania. South Africa is a biodiversity hotspot, with unique biomes, plant and animal life. With over 60 million people, the country is the world's 24th-most populous nation and covers an area of . South Africa has three capital cities, with the executive, judicial and legislative branches of government based in Pretoria, Bloemfontein, and Cape Town respectively. The largest city is Johannesburg. About 80% of the population are Black South Afri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robertson Karoo
Robertson Karoo is a semi-arid vegetation type, restricted to sections of the Breede River Valley, Western Cape Province, South Africa. It is a subtype of Succulent Karoo (geographically an extension of the "Little Karoo") and is characterised by the dominance of succulent plant species, and by several endemic plants and animals. Location and extent This vegetation type occurs in several large patches within the Breede River Valley, in the Western Cape Province of South Africa. It occurs in the area between Worcester in the north-west, Ashton in the east, and the Riviersonderend mountains in the south. Landscape and climate Robertson Karoo typically consists of low hills and flats covered in small succulent vegetation, usually growing on rocky shale-based soils. The climate is semi-arid due to the region lying in the rainshadow of the large mountain ranges to the south-west, but the rainfall does tend to occur mainly in winter. This vegetation type has a large number of ende ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overberg
__NOTOC__ Overberg is a region in South Africa to the east of Cape Town beyond the Hottentots-Holland mountains. It lies along the Western Cape Province's south coast between the Cape Peninsula and the region known as the Garden Route in the east. The boundaries of the Overberg are the Hottentots-Holland mountains in the West; the Riviersonderend Mountains, part of the Cape Fold Belt, in the North; the Atlantic and Indian Oceans in the South and the Breede River in the East. The area has always been considered as the breadbasket of the Cape and is largely given to grain farming — mainly wheat. The wheat fields are a major breeding ground for South Africa's national bird, the blue crane. Another important crop in the Overberg is fruit, with the Elgin Valley producing about 60 percent of the total annual apple crop of about 819 000 tonnes (2012 data). Nestled in the Overberg, one can find the Kogelberg Biosphere Reserve (recognised and registered with UNESCO) populated wi ...

Bredasdorp
Bredasdorp is a town in the Southern Overberg region of the Western Cape, South Africa, and the main economic and service hub of that region. It lies on the northern edge of the Agulhas Plain, about south-east of Cape Town and north of Cape Agulhas, the southernmost tip of Africa. Tourist attractions of Bredasdorp include the Heuningberg Nature Reserve, many historical churches, and art galleries and craft shops. Bredasdorp is also home to the Shipwreck Museum which tells the stories of the 150 wrecks along the nearby Agulhas Reef. It is the only museum of its kind in the southern hemisphere. History The town of Bredasdorp was founded with the building of a Dutch Reformed Church in 1838 on the farm Langefontein. The town was named after Michiel van Breda, the first Mayor of Cape Town, who was also known as the father of South Africa's merino sheep industry. Van Breda and Pieter Voltelyn van der Byl could not agree on a location for the church; as a result two churches were built ...

Endemic Flora Of The Cape Provinces
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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
