Didelta Spinosa
''Didelta spinosa '' (L.f.) Aiton, belonging to the family of Asteraceae, is a Southern African woody shrub or small tree endemic to the West Coast and found from Saldanha Bay in the south across the Gariep into the south-west corner of Namibia. Growing 2–3 m tall and drought-resistant, its preferred habitat is on dry, rocky slopes. This species was introduced to Europe by Thunberg and Masson. Leaves are opposite, shiny, oval to elliptic with margins rolled under (revolute) with irregular spine-tipped teeth - young leaves and twigs somewhat felted; flowers with an outer row of unusually large and leaf-like bracts with mucronate apices, and which become membranous with age; fruits in spine-fringed cells. Flowering takes place from midwinter to early spring. There are only 2 species in this genus, the other being ''Didelta carnosa'' (L.f.) Aiton. Recent phylogeny studies have placed the genus ''Didelta'' and ''Berkheya spinosissima'' on the same clade. The beetle '' Julodis v ...

Plantae
Plants are predominantly Photosynthesis, photosynthetic eukaryotes of the Kingdom (biology), 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 Glaucophyte, Glaucophyta, and consists of the green algae and Embryophyte, Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and Fern ally, 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 colo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between organisms ...

Brian Burtt
Brian Laurence "Bill" Burtt FRSE FLS (27 August 1913 – 30 May 2008), was an English botanist and taxonomist who is noted for his contributions to the family Gesneriaceae. In a career that spanned 74 years, he worked first at the Royal Botanic Gardens, Kew, and then at the Royal Botanic Garden Edinburgh (RBGE). He made numerous field trips to South Africa and Sarawak and described a total of 637 new plant species. Burtt is denoted by the author abbreviation when citing a botanical name. Education and career Brian Laurence Burtt, known to colleagues as Bill, was born 27 August 1913 in Claygate, Surrey, to Mabel Johnston and Laurence Buckley Burtt. He was educated at Dulwich College, excelling in Latin. After Dulwich he was employed at Kew as herbarium assistant to Arthur William Hill, the Director. Here he learnt to work with dried plant material from all over the world, painstakingly dissecting and classifying. Burtt wrote his first paper in 1932 with the assistance of Joh ...

Charles Louis L'Héritier De Brutelle
Charles Louis L'Héritier de Brutelle (; 15 June 1746 – 18 August 1800) was an 18th-century French botanist and civil servant. Born into an affluent upper-class Parisian family, connections with the French Royal Court secured him the position of Superintendent of Parisian Waters and Forests at the age of twenty-six. In this capacity, L'Héritier conducted various studies of native trees and shrubs, also gaining interest in exotic flora. The abbreviation L'Herit. is also used. Early life Apart from what is stated above, little is known of his early life before his first employment. He appears to have been self-taught in botany, after taking up the superintendency. In 1775 L'Héritier was appointed a magistrate in the ''Cour des Aides'' in Paris. This was a court which dealt with tax offences, but under its president Malesherbes it became perhaps the only French government institution to protect ordinary citizens against a corrupt state. Malesherbes himself was a keen botanist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grand Trianon
The Grand Trianon () is a French Baroque style château situated in the northwestern part of the Domain of Versailles in Versailles, France. It was built at the request of King Louis XIV of France as a retreat for himself and his ''maîtresse-en-titre'' of the time, the Marquise de Montespan, and as a place where he and invited guests could take light meals (''collations'') away from the strict ''étiquette'' of the royal court. The Grand Trianon is set within its own park, which includes the Petit Trianon (a smaller château built in the 1760s, during the reign of King Louis XV). ''Trianon de porcelaine'' Between 1663 and 1665, Louis XIV purchased the hamlet of Trianon, on the outskirts of Versailles. In 1670, he commissioned the architect Louis Le Vau to design a porcelain pavilion (''Trianon de porcelaine'') to be built there. The façade was made of white and blue Delft-style porcelain (ceramic) tiles from the French manufactures of Rouen, Lisieux, Nevers and Saint-Cl ...

Pierre Joseph Buchoz
Pierre-Joseph Buc'hoz (27 January 1731, in Metz – 13 January 1807, in Paris) was a French physician, lawyer and naturalist. Buc'hoz become a doctor of medicine in Nancy in 1763. He was devoted to botany, but was also interested in the treatment of melancholy and recommended music as therapy. He travelled throughout his native Lorraine and published a 13-volume of the province. Teaching botany as well, he was demonstrator at the . Author of many works of botany he also studied animals (in particular birds) and minerals In geology and mineralogy, a mineral or mineral species is, broadly speaking, a solid chemical compound with a fairly well-defined chemical composition and a specific crystal structure that occurs naturally in pure form.John P.

Didelta Spinosa08a
''Didelta'' is a genus of shrubs of up to 1 or 2 meter high, with two known species in the daisy family. Like in almost all Asteraceae, the individual flowers are 5-merous, small and clustered in typical heads, and are surrounded by an involucre, consisting of in this case two whorls of bracts, which are almost free from each other. The 3–5 outer bracts are protruding and triangular in shape, the inner about twice as many are lance-shaped and ascending. In ''Didelta'', the centre of the head is taken by 3–5 clusters of bisexual yolk yellow disc florets, sometimes divided from each other by male disc florets, and is surrounded by one complete whorl of infertile yolk yellow ray florets. The common base of the flowerhead swells around the developing fruitlets, become woody and breaks into segments when ripe. The fruitlets germinate within this woody encasing. The species of the genus ''Didelta'' can be found in Namibia and South Africa. The genus is called salad thistle in Eng ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nematode
The nematodes ( or grc-gre, Νηματώδη; la, Nematoda) or roundworms constitute the phylum Nematoda (also called Nemathelminthes), with plant-Parasitism, parasitic nematodes also known as eelworms. They are a diverse animal phylum inhabiting a broad range of environments. Less formally, they are categorized as Helminths, but are taxonomically classified along with Arthropod, arthropods, Tardigrade, tardigrades and other moulting animalia, animals in the clade Ecdysozoa, and unlike platyhelminthe, flatworms, have tubular digestion, digestive systems with openings at both ends. Like tardigrades, they have a reduced number of Hox genes, but their sister phylum Nematomorpha has kept the ancestral protostome Hox genotype, which shows that the reduction has occurred within the nematode phylum. Nematode species can be difficult to distinguish from one another. Consequently, estimates of the number of nematode species described to date vary by author and may change rapidly over ...
