Sartidia Jucunda
''Sartidia'' is a genus of Southern African and Madagascan plants in the grass family. It was split from '' Aristida'' in 1963 by South African botanist Bernard de Winter and contains six known species, of which '' Sartidia perrieri'' is considered extinct. Their natural habitats are warm, semi-arid savanna and dry forest at altitudes of where rainfall ranges from 250 to 1,500 mm per year. They are perennial grasses with inflorescence in a panicle. Other than most species in subfamily Aristidoideae, ''Sartidia'' species use the ancestral C photosynthetic pathway. Phylogenetic analyses suggest that ''Sartidia'' is the sister genus of ''Stipagrostis'', an important C genus from Africa and Southwest Asia. ; Species * ''Sartidia angolensis'' (C.E.Hubb.)

Sartidia Perrieri
''Sartidia perrieri'' is a grass species endemic to Madagascar, known from only one collected individual and now considered extinct. Henri Perrier de la Bâthie, in 1914, collected a plant in the central region of Madagascar, near Antsirabe, at an elevation of , where it grew on sandstone rocks in tapia woodland. He wrote in the description of the dried herbarium specimen that he only ever saw one individual of this species, suggesting it was already very rare at that time. Aimée Antoinette Camus named it after its collector and described it as new species in the genus '' Aristida''; Pierre Bourreil later transferred it to '' Sartidia''. ''Sartidia perrieri'' is a tuft-forming grass. The known individual is roughly high, with long leaf blades. Inflorescence is a dense, long panicle and the species has long awns extending from the lemmas in the spikelets. With its clusters of large spikelets, it is very different from the only other known ''Sartidia'' species from Ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C4 Photosynthesis
carbon fixation or the Hatch–Slack pathway is one of three known photosynthetic processes of carbon fixation in plants. It owes the names to the 1960's discovery by Marshall Davidson Hatch and Charles Roger Slack that some plants, when supplied with 14, incorporate the 14C label into four-carbon molecules first. fixation is an addition to the ancestral and more common carbon fixation. The main carboxylating enzyme in photosynthesis is called RuBisCO, which catalyses two distinct reactions using either (carboxylation) or oxygen (oxygenation) as a substrate. The latter process, oxygenation, gives rise to the wasteful process of photorespiration. photosynthesis reduces photorespiration by concentrating around RuBisCO. To ensure that RuBisCO works in an environment where there is a lot of carbon dioxide and very little oxygen, leaves generally differentiate two partially isolated compartments called mesophyll cells and bundle-sheath cells. is initially fixed in the m ...

Flora Of Africa
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. 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 Thurm ...

Limpopo
Limpopo is the northernmost province of South Africa. It is named after the Limpopo River, which forms the province's western and northern borders. The capital and largest city in the province is Polokwane, while the provincial legislature is situated in Lebowakgomo. The province is made up of 3 former homelands of Lebowa, Gazankulu and Venda and the former parts of the Transvaal province. The Limpopo province was established as one of the new nine provinces after South Africa's first democratic election on the 27th of April 1994. The province's name was first "Northern Transvaal", later changed to "Northern Province" on the 28th of June 1995, together with two other provinces. The name was later changed again in 2002 to the Limpopo province. Limpopo is made up of 3 main ethnic groups namely; Pedi people, Tsonga and Venda people. Traditional leaders and chiefs still form a strong backbone of the province's political landscape. Established in terms of the Limpopo House of Tra ...

Eswatini
Eswatini ( ; ss, eSwatini ), officially the Kingdom of Eswatini and formerly named Swaziland ( ; officially renamed in 2018), is a landlocked country in Southern Africa. It is bordered by Mozambique to its northeast and South Africa to its north, west, south, and southeast. At no more than north to south and east to west, Eswatini is one of the smallest countries in Africa; despite this, its climate and topography are diverse, ranging from a cool and mountainous highveld to a hot and dry lowveld. The population is composed primarily of ethnic Swazis. The prevalent language is Swazi (''siSwati'' in native form). The Swazis established their kingdom in the mid-18th century under the leadership of Ngwane III. The country and the Swazi take their names from Mswati II, the 19th-century king under whose rule the country was expanded and unified; its boundaries were drawn up in 1881 in the midst of the Scramble for Africa. After the Second Boer War, the kingdom, under the n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mpumalanga
Mpumalanga () is a province of South Africa. The name means "East", or literally "The Place Where the Sun Rises" in the Swazi, Xhosa, Ndebele and Zulu languages. Mpumalanga lies in eastern South Africa, bordering Eswatini and Mozambique. It constitutes 6.5% of South Africa's land area. It shares borders with the South African provinces of Limpopo to the north, Gauteng to the west, the Free State to the southwest, and KwaZulu-Natal to the south. The capital is Mbombela. Mpumalanga was formed in 1994, when the area that was the Eastern Transvaal was merged with the former bantustans KaNgwane, KwaNdebele and parts of Lebowa and Gazankulu. Although the contemporary borders of the province were only formed at the end of apartheid, the region and its surroundings has a history that extends back thousands of years. Much of its history, and current significance is as a region of trade. History Precolonial Era Archeological sites in the Mpumalanga region indicate settlem ...

Namibia
Namibia (, ), officially the Republic of Namibia, is a country in Southern Africa. Its western border is the Atlantic Ocean. It shares land borders with Zambia and Angola to the north, Botswana to the east and South Africa to the south and east. Although it does not border Zimbabwe, less than 200 metres (660 feet) of the Botswanan right bank of the Zambezi River separates the two countries. Namibia gained independence from South Africa on 21 March 1990, following the Namibian War of Independence. Its capital and largest city is Windhoek. Namibia is a member state of the United Nations (UN), the Southern African Development Community (SADC), the African Union (AU) and the Commonwealth of Nations. The driest country in sub-Saharan Africa, Namibia has been inhabited since pre-historic times by the San, Damara and Nama people. Around the 14th century, immigrating Bantu peoples arrived as part of the Bantu expansion. Since then, the Bantu groups, the largest being the ...
