Gerbera Jamesonii
''Gerbera jamesonii'' is a species of flowering plant in the genus ''Gerbera'' belonging to the basal Mutisieae tribe within the large Asteraceae (or Compositae) family. It is indigenous to South Eastern Africa and commonly known as the Barberton daisy,Siyabona Africa http://www.krugerpark.co.za/africa_barberton_daisy.html the Transvaal daisy, and as Barbertonse madeliefie or Rooigousblom in Afrikaans. It was the first species of Gerbera to be the subject of a scientific description, studied by J. D. Hooker in ''Curtis's Botanical Magazine'' in 1889. Etymology The genus was named in honour of German botanist and medical doctor Traugott Gerber (1710 — 1743). The ''Gerbera jamesonii'' was named in honour of Robert Jameson, who collected the plant near Barberton. The species epithet was proposed by the prominent South African botanist Harry Bolus, but first published by Richard Wills Adlam in 1888, so should be ascribed to him.

Mpumalanga
Mpumalanga () is one of the nine provinces of South Africa. The name means "East", or literally "The Place Where the Sun Rises" in the Nguni languages. Mpumalanga lies in eastern South Africa, bordering Eswatini and Mozambique. It shares borders with the South African provinces of Limpopo to the north, Gauteng to the west, the Free State (province), 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 (province), Transvaal was merged with the former bantustans KaNgwane, KwaNdebele and parts of Lebowa and Gazankulu. Although the contemporary borders of the province were formed only at the end of apartheid, the region and its surroundings have a history that extends back thousands of years. Much of its history and current significance are as a region of trade. History Precolonial Era Archeological sites in the Mpumalanga region indicate settlement by humans and ...

Rosette (botany)
In botany, a rosette is a circular arrangement of leaves or of structures resembling leaves. In flowering plants, rosettes usually sit near the soil, but they can also be at the top of an otherwise naked branch or trunk. Their structure is an example of a Aerial stem modification, modified stem in which the internode (botany), internode gaps between the leaves do not expand, so that all the leaves remain clustered tightly together and at a similar height. Some insects induce the development of Gall, galls that are leafy rosettes. In bryophytes and algae, a rosette results from the repeated branching of the thallus as the plant grows, resulting in a circular outline. Taxonomies Many plant family (taxonomy), families have varieties with rosette Morphology (biology), morphology; they are particularly common in Asteraceae (such as dandelions), Brassicaceae (such as cabbage), and Bromeliaceae. The fern ''Blechnum fluviatile'' or New Zealand Water Fern (''kiwikiwi'') is a rosette plan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flag Of Mpumalanga
The provincial flag of Mpumalanga was adopted in 1996, making the province the first of South Africa's Provinces of South Africa, nine provinces to make use of an official provincial flag. The other provinces currently use the province's coat of arms on a white background (except for Western Cape which uses a banner of arms). The design also features in the province's coat of arms. Design The canton of the flag is dominated by a stylised red Gerbera jamesonii, Barberton daisy, a plant which is indigenous to the province. The diagonal strip of blue and white separating the green and gold bars is meant to represent Great Escarpment, Southern Africa, the escarpment of the province's topology.

Tissue Culture
Tissue culture is the growth of tissue (biology), tissues or cell (biology), cells in an artificial medium separate from the parent organism. This technique is also called micropropagation. This is typically facilitated via use of a liquid, semi-solid, or solid growth medium, such as broth or agar. Tissue culture commonly refers to the culture of animal cells and tissues, with the more specific term plant tissue culture being used for plants. The term "tissue culture" was coined by American pathologist Montrose Thomas Burrows. Historical use In 1885 Wilhelm Roux removed a section of the medullary plate of an embryonic chicken and maintained it in a warm saline solution for several days, establishing the basic principle of tissue culture. In 1907 the zoologist Ross Granville Harrison demonstrated the growth of frog embryonic cells that would give rise to nerve cells in a medium of clotted lymph. In 1913, E. Steinhardt, C. Israeli, and R. A. Lambert grew vaccinia virus in fragme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cultivar
A cultivar is a kind of Horticulture, cultivated plant that people have selected for desired phenotypic trait, traits and which retains those traits when Plant propagation, propagated. Methods used to propagate cultivars include division, root and stem cuttings, offsets, grafting, micropropagation, tissue culture, or carefully controlled seed production. Most cultivars arise from deliberate human genetic engineering, manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word ''cultivar''''Cultivar'' () has two meanings, as explained in ''#Formal definition, Formal definition'': it is a classification category and a taxonomic unit within the category. When referring to a taxon, the word does not apply to an individual plant but to all plants t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gerbera Viridifolia
''Gerbera'' ( or ) L. is a genus of plants in the Asteraceae (Compositae) family. The first scientific description of a ''Gerbera'' was made by J. D. Hooker in Curtis's Botanical Magazine in 1889 when he described ''Gerbera jamesonii'', a South African species also known as ''Transvaal daisy'' or ''Barberton daisy''. Gerbera is also commonly known as the African daisy. Etymology The genus was named in honour of German botanist and medical doctor (1710–1743), who travelled extensively in Russia and was a friend of Carl Linnaeus. Description ''Gerbera'' species are tufted, caulescent, perennial herbs, often with woolly crown, up to 80 cm high. Leaves are all in rosette, elliptical with entire or toothed margin or lobed, petiolate or with a petaloid base, pinnately veined, often leathery and felted beneath. Single to several flowering stems from each rosette bear bracteate or ebracteate, simple, one-headed inflorescence-capitulum. Capitula are radiate, with several ...

Limpopo
Limpopo () is the northernmost Provinces of South Africa, province of South Africa. It is named after the Limpopo River, which forms the province's western and northern borders.
