Protea Cynaroides
''Protea cynaroides'', also called the king protea, is a flowering plant. It is a distinctive member of ''Protea'', having the largest head (botany), flower head in the genus. The species is also known as giant protea, honeypot or king sugar bush. It is widely distributed in the southwestern and southern parts of South Africa in the fynbos region. The king protea is the national flower of South Africa. It also is the flagship of thProtea Atlas Project run by the South African National Botanical Institute. The king protea has several colour forms and horticulturists have recognized 81 garden varieties, some of which have injudiciously been planted in its natural range. In some varieties the pink of the flower and red borders of leaves are replaced by a creamy yellow. This unusual flower has a long vase life in flower arrangements, and makes for an excellent dried flower. ''Protea cynaroides'' is adapted to survive wildfires by its thick underground stem, which contains many dorm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oceania
Oceania (, , ) is a region, geographical region that includes Australasia, Melanesia, Micronesia, and Polynesia. Spanning the Eastern Hemisphere, Eastern and Western Hemisphere, Western hemispheres, Oceania is estimated to have a land area of and a population of around 44.5 million as of 2021. When compared with (and sometimes described as being one of) the continents, the region of Oceania is the smallest in land area and the list of continents and continental subregions by population, second least populated after Antarctica. Its major population centres are Sydney, Melbourne, Brisbane, Perth, Auckland, Adelaide, Honolulu, and Christchurch. Oceania has a diverse mix of economies from the developed country, highly developed and globally competitive market economy, financial markets of Australia, French Polynesia, Hawaii, Hawaii, New Caledonia, and New Zealand, which rank high in quality of life and Human Development Index, to the much least developed countries, less developed ...

Southern Double-collared Sunbird
The southern double-collared sunbird or lesser double-collared sunbird (''Cinnyris chalybeus'') is a small passerine bird which breeds in southern Africa. It is mainly resident, but partially migratory in the north-east of its range. Habitat This sunbird is common in gardens, fynbos, forests and coastal scrub. The southern double-collared sunbird breeds from April to December, depending on region. The closed oval nest is constructed from grass, lichen and other plant material, bound together with spider webs. It has a side entrance which sometimes has a porch, and is lined with wool, plant down and feathers. Identification The southern double-collared sunbird is 12 cm long. The adult male has a glossy, metallic green head, throat, upper breast and back. It has a brilliant red band across the chest, separated from the green breast by a narrow metallic blue band. The rest of the underparts are whitish. When displaying, yellow feather tufts can be seen on the shoulders. As w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orange-breasted Sunbird
The orange-breasted sunbird (''Anthobaphes violacea'') is a species of small, predominantly nectar-feeding bird that is endemic to the fynbos shrubland biome of southwestern South Africa. It is the only member of the genus ''Anthobaphes'', in the family Nectariniidae (the sunbirds and spiderhunters), though it is sometimes placed in the genus ''Nectarinia''. The birds are sexually dimorphic, with females being olive green while the males are orange to yellow on the underside with bright green, blue and purple on the head and neck. Taxonomy In 1760 the French zoologist Mathurin Jacques Brisson included a description of the orange-breasted sunbird in his ''Ornithologie'', based on a specimen collected from the Cape of Good Hope. He used the French name ''Le petit grimpereau a longue queue du Cap de Bonne Espérance'' and the Latin ''Certhia Longicauda Minor Capitis Bonae Spei''. The two stars (**) at the start of the section indicates that Brisson based his description on the exami ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phosphorus
Phosphorus is a chemical element with the symbol P and atomic number 15. Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on Earth. It has a concentration in the Earth's crust of about one gram per kilogram (compare copper at about 0.06 grams). In minerals, phosphorus generally occurs as phosphate. Elemental phosphorus was first isolated as white phosphorus in 1669. White phosphorus emits a faint glow when exposed to oxygen – hence the name, taken from Greek mythology, meaning 'light-bearer' (Latin ), referring to the " Morning Star", the planet Venus. The term '' phosphorescence'', meaning glow after illumination, derives from this property of phosphorus, although the word has since been used for a different physical process that produces a glow. The glow of phosphorus is caused by oxidation of the white (but not red) phosphorus — a process now called chem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solubility
In chemistry, solubility is the ability of a substance, the solute, to form a solution with another substance, the solvent. Insolubility is the opposite property, the inability of the solute to form such a solution. The extent of the solubility of a substance in a specific solvent is generally measured as the concentration of the solute in a saturated solution, one in which no more solute can be dissolved. At this point, the two substances are said to be at the solubility equilibrium. For some solutes and solvents, there may be no such limit, in which case the two substances are said to be " miscible in all proportions" (or just "miscible"). The solute can be a solid, a liquid, or a gas, while the solvent is usually solid or liquid. Both may be pure substances, or may themselves be solutions. Gases are always miscible in all proportions, except in very extreme situations,J. de Swaan Arons and G. A. M. Diepen (1966): "Gas—Gas Equilibria". ''Journal of Chemical Physics'', ...

Proteoid Root
Cluster roots, also known as proteoid roots, are plant roots that form clusters of closely spaced short lateral rootlets. They may form a two- to five-centimetre-thick mat just beneath the leaf litter. They enhance nutrient uptake, possibly by chemically modifying the soil environment to improve nutrient solubilisation. As a result, plants with proteoid roots can grow in soil that is very low in nutrients, such as the phosphorus-deficient native soils of Australia. They were first described by Adolf Engler in 1894, after he discovered them on plants of the family Proteaceae growing in Leipzig Botanic Gardens. In 1960, Helen Purnell examined 44 species from ten Proteaceae genera, finding proteoid roots in every genus except ''Persoonia''; she then coined the name "proteoid roots" in reference to the plant family in which it was known to occur. Proteoid roots are now known to occur in 27 different Proteaceae genera, plus around 30 species from other families, including Betulaceae, Ca ...

Taproot
A taproot is a large, central, and dominant root from which other roots sprout laterally. Typically a taproot is somewhat straight and very thick, is tapering in shape, and grows directly downward. In some plants, such as the carrot, the taproot is a storage organ so well developed that it has been cultivated as a vegetable. The taproot system contrasts with the adventitious or fibrous root system of plants with many branched roots, but many plants that grow a taproot during germination go on to develop branching root structures, although some that rely on the main root for storage may retain the dominant taproot for centuries, for example ''Welwitschia''.Taproot also store nutrition. Plants with taproots are often vegetables. Description Dicots, one of the two divisions of flowering plants (angiosperms), start with a taproot, which is one main root forming from the enlarging radicle of the seed. The tap root can be persistent throughout the life of the plant but is most oft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...

Proteus
In Greek mythology, Proteus (; Ancient Greek: Πρωτεύς, ''Prōteus'') is an early prophetic sea-god or god of rivers and oceanic bodies of water, one of several deities whom Homer calls the "Old Man of the Sea" ''(hálios gérôn)''. Some who ascribe a specific domain to Proteus call him the god of "elusive sea change", which suggests the constantly changing nature of the sea or the liquid quality of water. He can foretell the future, but, in a mytheme familiar to several cultures, will change his shape to avoid doing so; he answers only to those who are capable of capturing him. From this feature of Proteus comes the adjective protean, meaning "versatile", "mutable", or "capable of assuming many forms". "Protean" has positive connotations of flexibility, versatility and adaptability. Name origin Proteus' name suggests the "first" (from Greek "πρῶτος" ''prōtos'', "first"), as ''prōtogonos'' (πρωτόγονος) is the "primordial" or the "firstborn". It is ...
