Leucospermum Pedunculatum
''Leucospermum pedunculatum'' is an evergreen, low shrub of high spreading from a single stern upright stem, from the family Proteaceae. The powdered or hairless line-shaped to somewhat sickle-shaped leaves are 3–6 cm (1.2–2.4 in) long and 2–5 mm (0.08–0.20 in) wide. The stalked, individually set flower heads are globe-shaped, 2½−3 cm (1.0−1.2 in) in diameter consist of initially white to pale cream flowers that eventually turn carmine. From the center of the flowers emerge straight styles that jointly give the impression of a pincushion. It is called white-trailing pincushion in English. It flowers from August to January, peaking in September. It is an endemic species that is restricted to a narrow strip on the south coast of the Western Cape province of South Africa. Description ''Leucospermum pedunculatum'' is a low spreading shrub of 15–30 cm (½–1 ft) high, that forms dense mats of up to 3 m (10 ft) in diameter ...

Johann Friedrich Klotzsch
Johann Friedrich Klotzsch (9 June 1805 – 5 November 1860) was a German pharmacist and botanist. His principal work was in the field of mycology, with the study and description of many species of mushroom. Klotzsch was born in Wittenberg. Originally trained as a pharmacist, he later enrolled in pharmaceutical and botanical studies in Berlin. In 1830–32 he was curator of William Jackson Hooker's herbarium at the University of Glasgow. Beginning in 1834 he collected plants in Saxony, Bohemia, Austria, Styria and possibly Hungary. In 1838 he replaced Adelbert von Chamisso (1781–1838) as curator and director of the Royal Herbarium in Berlin. The plant genus ''Klotzschia'' from the family Apiaceae, and some plant species like '' Eugenia klotzschiana'' or '' Acianthera klotzschiana'' are named in his honour. Selected works *''Mykologische Berichtigungen zu der nachgelassenen Sowerbyschen Sammlung, so wie zu den wenigen in Linneschen Herbarium vorhandenen Pilzen nebst Aufstellung ...

Carl Meissner
Carl Daniel Friedrich Meissner (1 November 1800 – 2 May 1874) was a Swiss botanist. Biography Born in Bern, Switzerland on 1 November 1800, he was christened Meisner but later changed the spelling of his name to Meissner. For most of his 40-year career he was Professor of Botany at University of Basel. He made important contributions to the botanical literature, including the publication of the comprehensive work ''Plantarum Vascularum Genera'', and publications of monographs on the families Polygonaceae (especially the genus ''Polygonum''), Lauraceae, Proteaceae, Thymelaeaceae and Hernandiaceae. His contributions to the description of the Australian flora were prolific; he described hundreds of species of Australian Proteaceae, and many Australian species from other families, especially Fabaceae, Mimosaceae and Myrtaceae. His health deteriorated after 1866, and he was less active. He died in Basel on 2 May 1874. See also * Meissner's taxonomic arrangement of Banksia Carl ...

Wildfire
A wildfire, forest fire, bushfire, wildland fire or rural fire is an unplanned, uncontrolled and unpredictable fire in an area of Combustibility and flammability, combustible vegetation. Depending on the type of vegetation present, a wildfire may be more specifically identified as a bushfire(bushfires in Australia, in Australia), desert fire, grass fire, hill fire, peat fire, prairie fire, vegetation fire, or veld fire. Fire ecology, Some natural forest ecosystems depend on wildfire. Wildfires are distinct from beneficial human usage of wildland fire, called controlled burn, controlled burning, although controlled burns can turn into wildfires. Fossil charcoal indicates that wildfires began soon after the appearance of terrestrial plants approximately 419 million years ago during the Silurian period. Earth's carbon-rich vegetation, seasonally dry climates, atmospheric oxygen, and widespread lightning and volcanic ignitions create favorable conditions for fires. The occurre ...

Table Mountain Sandstone
The Table Mountain Sandstone (TMS) is a group of rock formations within the Cape Supergroup sequence of rocks. Although the term "Table Mountain Sandstone" is still widely used in common parlance, the term TMS is no longer formally recognized; the correct name is the " Peninsula Formation Sandstone", which is part of the Table Mountain Group. The designation "Table Mountain Sandstone" will, however, in deference to the title, continue to be used in the rest of this article. The name is derived from the famous landmark in Cape Town, Table Mountain. Table Mountain Sandstone is made up predominantly of quartzitic sandstone laid down between 510 (Cambrian Period) and 400 (Silurian Period) million years ago. It is the hardest, and most erosion resistant layer of the Cape Supergroup. It therefore forms most of the highest and most conspicuous peaks in the Western Cape, as well as the steepest cliffs of the Cape Fold Mountains, despite being the oldest, and, therefore, low ...

Quaternary
The Quaternary ( ) is the current and most recent of the three periods of the Cenozoic Era in the geologic time scale of the International Commission on Stratigraphy (ICS). It follows the Neogene Period and spans from 2.58 million years ago to the present. The Quaternary Period is divided into two epochs: the Pleistocene (2.58 million years ago to 11.7 thousand years ago) and the Holocene (11.7 thousand years ago to today, although a third epoch, the Anthropocene, has been proposed but is not yet officially recognised by the ICS). The Quaternary Period is typically defined by the cyclic growth and decay of continental ice sheets related to the Milankovitch cycles and the associated climate and environmental changes that they caused. Research history In 1759 Giovanni Arduino proposed that the geological strata of northern Italy could be divided into four successive formations or "orders" ( it, quattro ordini). The term "quaternary" was introduced by Jules Desnoye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tertiary
Tertiary ( ) is a widely used but obsolete term for the geologic period from 66 million to 2.6 million years ago. The period began with the demise of the non-avian dinosaurs in the Cretaceous–Paleogene extinction event, at the start of the Cenozoic Era, and extended to the beginning of the Quaternary glaciation at the end of the Pliocene Epoch. The time span covered by the Tertiary has no exact equivalent in the current geologic time system, but it is essentially the merged Paleogene and Neogene periods, which are informally called the Early Tertiary and the Late Tertiary, respectively. The Tertiary established the Antarctic as an icy island continent. Historical use of the term The term Tertiary was first used by Giovanni Arduino during the mid-18th century. He classified geologic time into primitive (or primary), secondary, and tertiary periods based on observations of geology in Northern Italy. Later a fourth period, the Quaternary, was applied. In the early d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Danger Point
Danger Point is a coastal feature and cliff face in Devon (England), Devon, on the south coast of England. It is about southeast of the city of Exeter and about east of Exmouth, Devon, Exmouth and lies between the towns of Budleigh Salterton and Sidmouth. Geology and littoral ecology There are two rock sequences along the coast at Budleigh Salterton, the Pebble Beds and the "Otter Sandstone Formation". In the cliff face it is very apparent that both dip eastward. The "Budleigh Salterton Pebble Beds" are overlain by the sandstones that form the cliffs at Danger Point. Both sediments are markedly red, which indicates that they were formed in a desert in the hot dry climate of in the Triassic Period about 225 million years ago. The coastal path, south of the village of Otterton on the peninsula of Otter Sandstone, has many viewpoints and headlands from which the cliffs can be seen. However, there is no safe access to the seaward shore on any of the stretch between the southern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape Agulhas
Cape Agulhas (; pt, Cabo das Agulhas , "Cape of the Needles") is a rocky headland in Western Cape, South Africa. It is the geographic southern tip of the African continent and the beginning of the dividing line between the Atlantic and Indian Oceans according to the International Hydrographic Organization. Historically, the cape has been known to sailors as a major hazard on the traditional clipper route. It is sometimes regarded as one of the great capes. It was most commonly known in English as Cape L'Agulhas until the 20th century. The town of L'Agulhas is located near to the cape. Geography Cape Agulhas is located in the Overberg region, 170 kilometres (105 mi) southeast of Cape Town. The cape was named by Portuguese navigators, who called it ''Cabo das Agulhas''—Portuguese for "Cape of Needles"—after noticing that around the year 1500 the direction of magnetic north (and therefore the compass needle) coincided with true north in the region. The cape is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leucospermum
''Leucospermum'' is a genus of evergreen upright, sometimes creeping shrubs that is assigned to the Proteaceae, with currently forty-eight known species. Almost all species are easily recognised as ''Leucospermum'' because of the long protruding styles with a thickened pollen-presenter, which jointly give the flower head the appearance of a pincushion, its common name. Pincushions can be found in South Africa, Swaziland, Zimbabwe and Mozambique. The shrubs mostly have a single stem at their base, but some species sprout from an underground rootstock, from which the plant can regrow after fire has killed the above ground biomass. In a larger group of species, specimens are killed by fire, and their survival depends on the seeds. In all species, seeds are collected by ants, which take them to their underground nests to feed on their ant breads, a seed dispersal strategy known as myrmecochory. This ensures that the seeds do not burn, so new plants can grow from them. ''Leucospermum ... [...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 ...

Otto Kuntze
Carl Ernst Otto Kuntze (23 June 1843 – 27 January 1907) was a German botanist. Biography Otto Kuntze was born in Leipzig. An apothecary in his early career, he published an essay entitled ''Pocket Fauna of Leipzig''. Between 1863 and 1866 he worked as tradesman in Berlin and traveled through central Europe and Italy. From 1868 to 1873 he had his own factory for essential oils and attained a comfortable standard of living. Between 1874 and 1876, he traveled around the world: the Caribbean, United States, Japan, China, South East Asia, Arabian peninsula and Egypt. The journal of these travels was published as "Around the World" (1881). From 1876 to 1878 he studied Natural Science in Berlin and Leipzig and gained his doctorate in Freiburg with a monography of the genus '' Cinchona''.
