Tylecodon Paniculatus
''Tylecodon paniculatus'', also known as butter bush, butter tree, butterboom or rooisuikerblom (Afrikaans), is a species of succulent plant in the genus ''Tylecodon'' belonging to the family Crassulaceae. Etymology The genus name is a syllabic anagram of the former name ''Cotyledon'', created by Helmut Toelken who split a few species off into a genus of their own. The species Latin epithet refers to the shape of inflorescence — branched terminal panicles. The common names refer to soft, fleshy and brittle stems. For centuries children have used the soft, slippery stems as sleds. Description ''Tylecodon paniculatus'' is a thickset, robust succulent dwarf tree up to 2.5–3 m tall, with very fat stems with usually well branched rounded crown. The single main trunk and branches are covered with mustard-yellow to olive-green bark peeling in papery semi-translucent sheets. Branches are short, with prominent leaf scars. Leaves are clustered and spirally arranged around the apex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Linnaeus The Younger
Carl Linnaeus the Younger, Carolus Linnaeus the Younger, Carl von Linné den yngre (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 (outdated) or L.f. (modern) as a botanical authority; 20 January 1741 – 1 November 1783) was a Swedish naturalist.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 nine and was taught science by his father's 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 '' Supplementum Plantarum systematis vegetabilium'' of 1781, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stamen
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains ''sporangium, microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna (plant), Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea'' ...

Plants Described In 1978
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ability ...

Anysberg Nature Reserve
The Anysberg Nature Reserve of 62,500 ha, is situated in the western Little Karoo region of the Gouritz Cluster Biosphere Reserve in the Western Cape province, South Africa. The central mountain is named after Anise, ''Pimpinella anisum'', which is found in the reserve. The reserve was established in 1984, to conserve succulent and fynbos flora in the Cape Fold Belt, and to reintroduce game which formerly occurred here. The nearest towns are Laingsburg and Ladismith, which are both about 55 km from the main reserve entrance. History Land for the reserve was first set aside in 1984 below the Anysberg Mountain Catchment Area (designated in 1978). This was further extended multiple times to its current area of . Biodiversity Fed by three rivers, the diversity of life is supported here amidst mountain feathers and the characteristic Klein Karoo veil. About 180 species of birds are regularly spotted in the reserve, making it a popular choice for bird watchers. In additi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

De Doorns
De Doorns is situated in the Breede Valley Local Municipality, Cape Winelands District Municipality in the Western Cape province of South Africa. Location It lies in the Hex River Valley on the N1 National Route, 32 km north-east of Worcester and 40 km south-west of Touwsrivier. It is in the centre of an export grape growing region, surrounded by over 200 table grape farms. History The town takes its name from the farm "De Doorns boven aan de Hex Rivier" (‘the thorns on the upper Hex River’), known as early as 1725. The area was declared a sub-drosty of Tulbagh in 1819 and the farm became the seat of the area's own drostdy in 1822. The De Doorns farm was bought by the government of Cape Prime Minister John Molteno in 1875, to build a railway station for the rapidly expanding Cape Government Railways. The line was immediately built through De Doorns, connecting it to Cape Town on the coast and reaching Montagu Road(later Touws River) in 1877, on its way to Kimberl ...

Richtersveld
The Richtersveld is a desert landscape characterised by rugged kloofs and high mountains, situated in the north-western corner of South Africa’s Northern Cape province. It is full of changing scenery from flat, sandy, coastal plains, to craggy sharp mountains of volcanic rock and the lushness of the Orange River, which forms the border with neighboring Namibia. The area ranges in altitude from sea level, to at Cornellberg. Located in the north-western side of the Northern Cape province in South Africa, the Richtersveld is regarded as the only arid biodiversity hotspot on earth and the majority of the area is inscribed on UNESCO's World Heritage List due to its cultural values. The Nama people of Richtersveld claimed title to their traditional land and set aside this conservancy for future research and tourism. The northern part of the area was proclaimed in 1991 after 18 years of negotiations between the National Parks Board and the local Nama people who continue to liv ...

Cardiac Glycoside
Cardiac glycosides are a class of organic compounds that increase the output force of the heart and decrease its rate of contractions by inhibiting the cellular sodium-potassium ATPase pump. Their beneficial medical uses are as treatments for congestive heart failure and cardiac arrhythmias; however, their relative toxicity prevents them from being widely used. Most commonly found as secondary metabolites in several plants such as foxglove plants, these compounds nevertheless have a diverse range of biochemical effects regarding cardiac cell function and have also been suggested for use in cancer treatment. Classification General structure The general structure of a cardiac glycoside consists of a steroid molecule attached to a sugar (glycoside) and an R group. The steroid nucleus consists of four fused rings to which other functional groups such as methyl, hydroxyl, and aldehyde groups can be attached to influence the overall molecule's biological activity.

Bufadienolide
Bufadienolide is a chemical compound with steroid structure. Its derivatives are collectively known as bufadienolides, including many in the form of bufadienolide glycosides (bufadienolides that contain structural groups derived from sugars). These are a type of cardiac glycoside, the other being the cardenolide glycosides. Both bufadienolides and their glycosides are toxic; specifically, they can cause an atrioventricular block, bradycardia (slow heartbeat), ventricular tachycardia (a type of rapid heartbeat), and possibly lethal cardiac arrest. Etymology The term derives from the toad genus ''Bufo'' that contains bufadienolide glycosides, the suffix ''-adien-'' that refers to the two double bonds in the lactone ring, and the ending ''-olide'' that denotes the lactone structure. Consequently, related structures with only one double bond are called ''bufenolides'', and the saturated equivalent is ''bufanolide''.
