Aptenia Cordifolia
''Mesembryanthemum cordifolium'', formerly known as ''Aptenia cordifolia'', is a species of succulent plant in the iceplant family. It is a creeping plant that forms a carpet of flat-growing perennial herbs in groups on the ground from a base. The genus name means middle-embryo flower in reference to the position of the ovary in the flower. The specific epithet is derived from Latin for heart-shaped leaves. Description This is a succulent, creeping, short-lived, mat-forming perennial herb growing in flat clumps on the ground from a woody base. Plants only rise to about tall but prostrate stems reach up to about long. The stems are green and stalk-round. The fleshy, small leaves are opposite, ovate to cordate, about long and covered with fine papillae. Bright pink to purplish solitary flowers appear in the leaf axils, open during the day but close up at night and remain closed on cloudy days. These colored whorls are not petals, but non-functional modified stamens. Norm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carolus Linnaeus The Younger
Carl Linnaeus the Younger, Carolus Linnaeus the Younger, Carl von Linné den yngre (Swedish language, Swedish; abbreviated Carl von Linné d. y.), or ''Linnaeus filius'' (Latin for ''Linnaeus the son''; abbreviated L.fil. (outdated) or L.f. (modern) as a botanical authority; 20 January 1741 – 1 November 1783) was a Swedish natural history, naturalist. His names distinguish him from his father, the pioneering taxonomist Carl Linnaeus (1707–1778). Biography Carl Linnaeus the Younger was enrolled at the University of Uppsala at the age of 9 and was taught science by his father's List of students of Linnaeus, students, including Pehr Löfling, Daniel Solander, and Johan Peter Falk. In 1763, aged just 22, he succeeded his father as the head of Practical Medicine at Uppsala. His promotion to professor — without taking exams or defending a thesis — caused resentment among his colleagues. His work was modest in comparison to that of his father. His best-known work is the ''Su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whorl (botany)
In botany, a whorl or verticil is a whorled arrangement of Leaf, leaves, sepals, petals, stamens, or Gynoecium#Carpels, carpels that radiate from a single point and surround or wrap around the stem or stalk. A leaf whorl consists of at least three elements; a pair of opposite leaves is not called a whorl. For leaves to grow in whorls is fairly rare except in plant species with very short Plant stem, internodes and some other genera (''Galium'', ''Nerium'', ''Elodea'' etc.). Leaf whorls occur in some trees such as ''Brabejum stellatifolium'' and other species in the family Proteaceae (e.g., in the genus ''Banksia''). In plants such as these, crowded internodes within the leaf whorls alternate with long internodes between the whorls. The Morphology (biology), morphology of most flowers (called cyclic flowers) is based on four types of whorls: # The Sepal, calyx: zero or more whorls of sepals at the base # The Petal, corolla: zero or more whorls of petals above the calyx # The Stam ...

Eastern Cape
The Eastern Cape ( ; ) is one of the nine provinces of South Africa. Its capital is Bhisho, and its largest city is Gqeberha (Port Elizabeth). Due to its climate and nineteenth-century towns, it is a common location for tourists. It is also known for having been home to many anti-apartheid activists, including Nelson Mandela. The second largest province in the country (at 168,966 km2) after the Northern Cape, it was formed in 1994 out of the Xhosa people, Xhosa homelands or bantustans of Transkei and Ciskei, together with the eastern portion of the Cape Province. The central and eastern part of the province is the traditional home of the indigenous Xhosa people. In 1820 this area, which was known as the Xhosa Kingdom, began to be settled by Europeans who originally came from England, Scotland and Ireland. Eastern Cape is the only province in South Africa were the number of Black Africans declined from 86.6% to 85.7% since Apartheid ended in 1994. History The Eastern Cape p ...

Purple
Purple is a color similar in appearance to violet light. In the RYB color model historically used in the arts, purple is a secondary color created by combining red and blue pigments. In the CMYK color model used in modern printing, purple is made by combining magenta pigment with either cyan pigment, black pigment, or both. In the RGB color model used in computer and television screens, purple is created by mixing red and blue light in order to create colors that appear similar to violet light. According to color theory, purple is considered a cool color. Purple has long been associated with royalty, originally because Tyrian purple dye—made from the secretions of sea snails—was extremely expensive in antiquity. Purple was the color worn by Roman magistrates; it became the imperial color worn by the rulers of the Byzantine Empire and the Holy Roman Empire, and later by Roman Catholic bishops. Similarly in Japan, the color is traditionally associated with the emperor a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magenta
Magenta () is a purple-red color. On color wheels of the RGB color model, RGB (additive) and subtractive color, CMY (subtractive) color models, it is located precisely midway between blue and red. It is one of the four colors of ink used in color printing by most Color printing, color printers, along with yellow, cyan, and black to make all the other colors. Magenta is a color made by mixing red and blue. The tone of magenta used in printing, Shades of magenta, printer's magenta, is redder than the magenta of the RGB (additive) model, the former being closer to Rose (color), rose. Magenta took its name from an aniline dye made and patented in 1859 by the French chemist François-Emmanuel Verguin, who originally called it ''fuchsine''. It was renamed to celebrate the French-Sardinian victory under French Emperor Napoleon III at the Battle of Magenta against the larger army of the Austrian Empire on 4 June 1859 near the Italian town of Magenta, Lombardy, Magenta, at the time in Au ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera. Hybrids are not always intermediates between their parents such as in blending inheritance (a now discredited theory in modern genetics by particulate inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridization, which include genetic and morph ...

Angiosperm Phylogeny Group
The Angiosperm Phylogeny Group (APG) is an informal international group of systematic botanists who collaborate to establish a consensus on the taxonomy of flowering plants (angiosperms) that reflects new knowledge about plant relationships discovered through phylogenetic studies. , four incremental versions of a classification system have resulted from this collaboration, published in 1998, 2003, 2009 and 2016. An important motivation for the group was what they considered deficiencies in prior angiosperm classifications since they were not based on monophyletic groups (i.e., groups that include all the descendants of a common ancestor). APG publications are increasingly influential, with a number of major herbaria changing the arrangement of their collections to match the latest APG system. Angiosperm classification and the APG In the past, classification systems were typically produced by an individual botanist or by a small group. The result was a large number of systems ...

Sunshine
Sunlight is the portion of the electromagnetic radiation which is emitted by the Sun (i.e. solar radiation) and received by the Earth, in particular the visible light perceptible to the human eye as well as invisible infrared (typically perceived by humans as warmth) and ultraviolet (which can have physiological effects such as sunburn) lights. However, according to the American Meteorological Society, there are "conflicting conventions as to whether all three ..are referred to as light, or whether that term should only be applied to the visible portion of the spectrum." Upon reaching the Earth, sunlight is scattered and filtered through the Earth's atmosphere as daylight when the Sun is above the horizon. When direct solar radiation is not blocked by clouds, it is experienced as sunshine, a combination of bright light and radiant heat (atmospheric). When blocked by clouds or reflected off other objects, sunlight is diffused. Sources estimate a global average of be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IsiZulu
Zulu ( ), or isiZulu as an endonym, is a Southern Bantu language of the Nguni branch spoken in, and indigenous to, Southern Africa. Nguni dialects are regional or social varieties of the Nguni language, distinguished by vocabulary, pronunciation, grammar, and other linguistic features. So, Zulu is one of the Nguni dialects which is spoken by the Zulu people, with about 13.56 million native speakers, who primarily inhabit the province of KwaZulu-Natal in South Africa. The word "KwaZulu-Natal" translates into English as "Home of the Zulu Nation is Natal". Zulu is the most widely spoken home language in South Africa (24% of the population), and it is understood by over 50% of its population. It became one of South Africa's 12 official languages in 1994. According to Ethnologue, it is the second-most widely spoken of the Bantu languages, after Swahili. Like many other Bantu languages, it is written with the Latin alphabet. In South African English, the language is often referred ...

Afrikaans
Afrikaans is a West Germanic languages, West Germanic language spoken in South Africa, Namibia and to a lesser extent Botswana, Zambia, Zimbabwe and also Argentina where there is a group in Sarmiento, Chubut, Sarmiento that speaks the Patagonian Afrikaans, Patagonian dialect. It evolved from the Dutch language, Dutch vernacular of South Holland (Hollandic dialect) spoken by the free Burghers, predominantly Dutch settlers and slavery in South Africa#Dutch rule, enslaved population of the Dutch Cape Colony, where it gradually began to develop distinguishing characteristics in the 17th and 18th centuries. Although Afrikaans has adopted words from other languages including German language, German, Malay language, Malay and Khoisan languages, an estimated 90 to 95% of the vocabulary of Afrikaans is of Dutch origin. Differences between Afrikaans and Dutch often lie in the more analytic language, analytic Morphology (linguistics), morphology and grammar of Afrikaans, and differ ...

Variegation
'' Cryptocarya williwilliana'' showing leaf venation and variegated leaves Variegation is the appearance of differently coloured zones in the foliage, flowers, and sometimes the stems and fruit of plants, granting a speckled, striped, or patchy appearance. The colors of the patches themselves vary from a slightly lighter shade of the natural coloration to yellow, to white, or other colors entirely such as red and pink. This is caused by varying levels and types of pigment, such as chlorophyll in leaves. Variegation can be caused by genetic mutations affecting pigment production, or by viral infections such as those resulting from mosaic viruses. Many plants are also naturally variegated, such as '' Goeppertia insignis''. Most of these are herbaceous or climbing plants, and are most often species native to tropical rainforests. Many species which are normally non-variegated are known to display variegation. Their appearance is desirable to enthusiasts, and many such plants ar ...
