Felicia Brevifolia
''Felicia brevifolia'' is an evergreen, richly branched shrub of up to 1 m (5 ft) high, that is assigned to the family Asteraceae. It has elliptic to wedge-shaped leaves, of between and 1 cm long, green to gray-green, many with several teeth. The flower heads have about fifteen blue-violet ray florets, encircling many yellow disc florets. This species grows in southern Namibia and the west of South Africa. Description ''Felicia brevifolia'' is an evergreen, upright, up to 1 m (5 ft) high shrub, very woody and leafless at the base, covered in a fibrous, gray-brown bark. The older shoots support dense-leaved short shoots, and are topped by young long shoots. The leaves are alternately set, of very different size, between long and wide to long and wide, elliptic to wedge-shaped, without or with (sometimes up to ten) pointed-ovate teeth, with or nearly without a leaf stalk. The surface of the leaves may be carry short bristles, or bristles and glandular ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dehiscence (botany)
Dehiscence is the splitting of a mature plant structure along a built-in line of weakness to release its contents. This is common among fruits, anthers and sporangia. Sometimes this involves the complete detachment of a part; structures that open in this way are said to be dehiscent. Structures that do not open in this way are called indehiscent, and rely on other mechanisms such as decay or predation to release the contents. A similar process to dehiscence occurs in some flower buds (e.g., ''Platycodon'', ''Fuchsia''), but this is rarely referred to as dehiscence unless wikt:circumscissile, circumscissile dehiscence is involved; anthesis is the usual term for the opening of flowers. Dehiscence may or may not involve the loss of a structure through the process of abscission. The lost structures are said to be wikt:caducous, caducous. Association with crop breeding Manipulation of dehiscence can improve crop yield since a Trait (biological), trait that causes seed dispersal i ...

Ceres, Western Cape
Ceres is the administrative centre and largest town of the Witzenberg Local Municipality in the Western Cape Province of South Africa. Ceres serves as a regional centre for the surrounding towns of Wolseley, Tulbagh, Op-die-Berg and Prince Alfred Hamlet. It is situated in the ''Warmbokkeveld'' (Afrikaans: "warm antelope field") Valley about 170 km north-east of Cape Town. Ceres is located at the north-eastern entrance to Michell's Pass and was the old route north between Cape Town and Johannesburg, which was later replaced by the N1 highway, which traverses the Breede River Valley to the south. Named after the Roman goddess of agriculture, Ceres, a name which is fitting as the valley in which the town is situated is extremely fertile and is a major producer of South Africa's deciduous fruit. Geography and climate Ceres experiences a typical Mediterranean climate tempered by its altitude. The town experiences warmer temperatures in summer, due to its inland location with ...

Calvinia
Calvinia is a regional town in the Northern Cape province of South Africa named after the French people, French religious reformer Jean Calvin. The town falls under the Hantam Local Municipality which forms part of the Namakwa District Municipality. The Calvinia district is part of the Great Karoo region of South Africa. The town is just south of the Hantam mountains on the banks of the Oorlogskloof (meaning "War Ravine") River. Calvinia enjoys 80% starlight and is renowned for its kaleidoscope of spring wildflowers coinciding with the Namaqualand wildflower spectacle. An asteroid (1245 Calvinia) is named after the town. History The earliest known people living in the area were Khoisan people. The first Europeans in the area were farmers who took their livestock to the area in the 1750s. On 19 January 1847, at a meeting on the farm Tygerhoek, a new Dutch Reformed Church congregation was founded for the Hantam region. In 1848 the congregation bought 1,200 hectares of the farm H ...

Lüderitz
Lüderitz is a town in the ǁKaras Region of southern Namibia. It lies on one of the least hospitable coasts in Africa. It is a port developed around Robert Harbour and Shark Island. The town is known for its colonial architecture, including some Art Nouveau work, and for wildlife including seals, penguins, flamingos and ostriches. It is also home to a museum, and lies at the end of a decommissioned railway line to Keetmanshoop. The town is named after Adolf Lüderitz, founder of the German South West Africa colony. Economy and infrastructure The centre of Lüderitz' economic activity is the port, until the incorporation of the exclave Walvis Bay in 1994 the only suitable harbour on Namibia's coast. However, the harbour at Lüderitz has a comparatively shallow rock bottom, making it unusable for many modern ships. The recent addition of a new quay has allowed larger fishing vessels to dock at Lüderitz. The town has also re-styled itself in an attempt to lure tourists t ...

Felicia (plant)
''Felicia'' is a genus of small shrubs, perennial or annual herbaceous plants, with 85 known species, that is assigned to the daisy family (Compositae or Asteraceae). Like in almost all Asteraceae, the individual flowers are 5-merous, small and clustered in typical heads, and which are surrounded by an involucre of, in this case between two and four whorls of, bracts. In ''Felicia'', the centre of the head is taken by yellow, seldom whitish or blackish blue disc florets, and is almost always surrounded by one single whorl of mostly purple, sometimes blue, pink, white or yellow ligulate florets and rarely ligulate florets are absent. These florets sit on a common base (or receptacle) and are not individually subtended by a bract (or palea). Most species occur in the Cape Floristic Region, which is most probably the area where the genus originates and had most of its development. Some species can be found in the eastern half of Africa up to Sudan and the south-western Arabian pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Section (botany)
In botany, a section ( la, sectio) is a taxonomic rank below the genus, but above the species. The subgenus, if present, is higher than the section, and the rank of series, if present, is below the section. Sections may in turn be divided into subsections.Article 4 in Sections are typically used to help organise very large genera, which may have hundreds of species. A botanist wanting to distinguish groups of species may prefer to create a taxon at the rank of section or series to avoid making new combinations, i.e. many new binomial names for the species involved. Examples: * ''Lilium'' sectio ''Martagon'' Rchb. are the Turks' cap lilies * ''Plagiochila aerea'' Taylor is the type species of ''Plagiochila'' sect. ''Bursatae'' See also * Section (biology) References Section Section, Sectioning or Sectioned may refer to: Arts, entertainment and media * Section (music), a complete, but not independent, musical idea * Section (typography), a subdivision, especially ...

Synonymy (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia leva ...

Kurt Dinter
Moritz Kurt Dinter (10 June 1868 – 16 December 1945) was a German botanist and explorer in South West Africa. Education and career Dinter was born in Bautzen, where he attended the Realschule. Having completed his military service and joined the Botanic Gardens at Dresden and Strasbourg to further his botanical and horticultural interests. He was appointed assistant to Prof. Carl Georg Oscar Drude, the plant geographer, in Dresden. As a result of his keen interest in exotic succulents, he was selected by Sir Thomas Hanbury to manage his acclimatisation garden, the Giardini Botanici Hanbury at La Mortola, near Ventimiglia on the Italian Riviera. This garden had a large collection of South African bulbs and succulents. He also spent about six months at Kew, returned to La Mortola and decided on a trip to South West Africa. He landed at Swakopmund in June 1897, having sailed on the "Melitta Bohlem". Dinter started his collection in the countryside around Swakopmund, moved on ...

Augustin Pyramus De Candolle
Augustin Pyramus (or Pyrame) de Candolle (, , ; 4 February 17789 September 1841) was a Swiss botanist. René Louiche Desfontaines launched de Candolle's botanical career by recommending him at a herbarium. Within a couple of years de Candolle had established a new genus, and he went on to document hundreds of plant families and create a new natural plant classification system. Although de Candolle's main focus was botany, he also contributed to related fields such as phytogeography, agronomy, paleontology, medical botany, and economic botany. De Candolle originated the idea of "Nature's war", which influenced Charles Darwin and the principle of natural selection. de Candolle recognized that multiple species may develop similar characteristics that did not appear in a common evolutionary ancestor; a phenomenon now known as convergent evolution. During his work with plants, de Candolle noticed that plant leaf movements follow a near-24-hour cycle in constant light, suggestin ...
