Leucospermum Calligerum
''Leucospermum calligerum'' is a softly hairy shrub, with wand-like branches, entire ovate leaves that have a bony tip of about 25 × 6 mm (1 × ¼ in), and globular heads of 2–3½ cm (0.8–1.4 in) in diameter, with two to six together near the tip of the branches and flowering in turn, that consist of Merosity, 4-merous flowers, initially cream-colored, later pink, with the petals curled and the styles 2–2½ cm (0.8–1.0 in) long, sticking out like pins from a cushion. It is called arid pincushion or common louse pincushion in English and rooiluisie in Afrikaans. Well-scented flowers can be found from July to January. It naturally occurs in fynbos in the Northern Cape and Western Cape provinces of South Africa. Description ''Leucospermum calligerum'' is a shrub of ½–2 m (1½–6 ft) high and up to in circumference, with a single main stem at its foot, Virgate (botany), wand-shaped stems, Divaricate, branching at wide angles, initially horizontal o ...

Pollen-presenter
A pollen-presenter is an area on the tip of the style in flowers of plants of the family Proteaceae on which the anthers release their pollen prior to anthesis. To ensure pollination, the style grows during anthesis, sticking out the pollen-presenter prominently, and so ensuring that the pollen easily contacts the bodies of potential pollination vectors such as bees, birds and nectarivorous mammals. The systematic depositing of pollen on the tip of the style implies the plants have some strategy to avoid excessive self-pollination Self-pollination is a form of pollination in which pollen from the same plant arrives at the stigma of a flower (in flowering plants) or at the ovule (in gymnosperms). There are two types of self-pollination: in autogamy, pollen is transferred .... References * Plant anatomy + Proteaceae {{Botany-stub ...

Proteaceae
The Proteaceae form a family of flowering plants predominantly distributed in the Southern Hemisphere. The family comprises 83 genera with about 1,660 known species. Together with the Platanaceae and Nelumbonaceae, they make up the order Proteales. Well-known genera include ''Protea'', ''Banksia'', ''Embothrium'', ''Grevillea'', ''Hakea'' and ''Macadamia''. Species such as the New South Wales waratah (''Telopea speciosissima''), king protea (''Protea cynaroides''), and various species of ''Banksia'', ''soman'', and ''Leucadendron'' are popular cut flowers. The nuts of ''Macadamia integrifolia'' are widely grown commercially and consumed, as are those of Gevuina avellana on a smaller scale. Australia and South Africa have the greatest concentrations of diversity. Etymology The name Proteaceae was adapted by Robert Brown from the name Proteae coined in 1789 for the family by Antoine Laurent de Jussieu, based on the genus ''Protea'', which in 1767 Carl Linnaeus derived from t ...

On The Cultivation Of The Plants Belonging To The Natural Order Of Proteeae
''On the cultivation of the plants belonging to the natural order of Proteeae'' is an 1809 paper on the family Proteaceae of flowering plants. Although nominally written by Joseph Knight as a paper on cultivation techniques, all but 13 pages consists of an unattributed taxonomic revision now known to have been written by Richard Salisbury. Publication of the paper triggered one of the most bitter disputes in 19th century botany, because Salisbury had preempted the publication of numerous plant names that Robert Brown had intended to publish. Brown's paper had already been read to the Linnean Society of London, at meeting which Salisbury had attended, but his paper had not yet made it to print. In publishing this paper before Brown's ''On the natural order of plants called Proteaceae'' had been printed, Salisbury beat Brown to print, claiming priority for the names that Brown had authored. As a result of this, Salisbury was accused of plagiarism and ostracised from botanical cir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Superfluous Name
''Nomen illegitimum'' (Latin for illegitimate name) is a technical term, used mainly in botany. It is usually abbreviated as ''nom. illeg.'' Although the International Code of Nomenclature for algae, fungi, and plants uses Latin terms for other kinds of name (e.g. ''nomen conservandum'' for "conserved name"), the glossary defines the English phrase "illegitimate name" rather than the Latin equivalent.''Melbourne Code''Glossary/ref> However, the Latin abbreviation is widely used by botanists and mycologists. A superfluous name is often an illegitimate name. Again, although the glossary defines the English phrase, the Latin equivalent ''nomen superfluum'', abbreviated ''nom. superfl.'' is widely used by botanists. Definition A ''nomen illegitimum'' is a validly published name, but one that contravenes some of the articles laid down by the International Botanical Congress.

Leucospermum Oleifolium
''Leucospermum oleifolium'' is an erect shrub of about high and 1½ m (5 ft) across that is assigned to the family Proteaceae. It has spreading branches, densely set with initially felty, entire, oval, olive-colored leaves of about 3½ cm (1½ in) long and 1½ cm (0.6 in) wide, with a bony tip that sometimes has two to five blunt teeth, with a blunt base and conspicuous veins. The flowers and their long thread-like styles are initially sulfur yellow, but soon become orange and finally turn brilliant crimson. The flower heads are about in diameter, crowded at the tip of the branches with a maximum of five that start flowering in turn. This provides for a colour spectacle from August till December. It is called by various names in South Africa such as Overberg pincushion, flame pincushion, mix pincushion and tuft pincushion. It naturally occurs in fynbos in the Western Cape province of South Africa. Description ''Leucospermum oleifolium'' is an erect, usually compact ...

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] |

Little Karoo
The Karoo ( ; from the Afrikaans borrowing of the South Khoekhoe !Orakobab or Khoemana word ''ǃ’Aukarob'' "Hardveld") is a semi-desert natural region of South Africa. No exact definition of what constitutes the Karoo is available, so its extent is also not precisely defined. The Karoo is partly defined by its topography, geology and climate, and above all, its low rainfall, arid air, cloudless skies, and extremes of heat and cold.Potgieter, D.J. & du Plessis, T.C. (1972) ''Standard Encyclopaedia of Southern Africa''. Vol. 6. pp. 306–307. Nasou, Cape Town.''Reader’s Digest Illustrated Guide to Southern Africa''. (5th Ed. 1993). pp. 78–89. Reader’s Digest Association of South Africa Pty. Ltd., Cape Town. The Karoo also hosted a well-preserved ecosystem hundreds of million years ago which is now represented by many fossils. The ǃ’Aukarob formed an almost impenetrable barrier to the interior from Cape Town, and the early adventurers, explorers, hunters, and travelers o ...

Swartberg
The Swartberg mountains (''black mountain'' in Afrikaans) are a mountain range in the Western Cape province of South Africa. It is composed of two main mountain chains running roughly east–west along the northern edge of the semi-arid Little Karoo. To the north of the range lies the other large semi-arid area in South Africa, the Great Karoo. Most of the Swartberg Mountains are above 2000 m high, making them the tallest mountains in the Western Cape. It is also one of the longest, spanning some 230 km from south of Laingsburg in the west to between Willowmore and Uniondale in the east. Geologically, these mountains are part of the Cape Fold Belt. Much of the Swartberg is part of a UNESCO World Heritage Site. The two ranges The Swartberg consists of two officially named ranges, the Smaller and the Greater Swartberg Mountains. ''Klein Swartberge'' The Smaller Swartberg are the westernmost of the two. Ironically, this range is the higher one, including the province's high ...
