Gonospermum Ptarmiciflorum
''Gonospermum ptarmiciflorum'', formerly ''Tanacetum ptarmiciflorum'', is a shrub with silvery leaves in the family Asteraceae.

Philip Barker Webb
Philip Barker Webb (10 July 1793 – 31 August 1854) was an English botanist. Life Webb was born to a wealthy, aristocratic family; his father was the lord of the manors of Witley and Milford, Surrey, Milford, in Surrey, England. Webb was educated at Harrow School and Christ Church, Oxford. He collected plants in Italy, Spain, and Portugal, and was the first person to collect in the Tetuan Mountains of Morocco. En route to Brazil he made what was intended to be a brief visit to the Canary Islands, but he stayed for a considerable time, returning after his Brazil expedition. The results can be seen in the nine-volume ''Natural History of the Canary Islands, Histoire Naturelle des Iles Canaries'' (''Natural History of the Canary Islands''), which he co-authored with Sabin Berthelot. In company with Berthelot, who had lived on the islands for some time, Webb collected specimens on the islands between 1828 and 1830. The text of ''Histoire Naturelle des Iles Canaries'' took 20&nb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sabin Berthelot
Sabin Berthelot (4 April 1794 – 10 November 1880) was a French naturalist and ethnologist. He was resident on the Canary Islands for part of his life, and co-authored ''L'Histoire Naturelle des Îles Canaries'' (1835–50) with Philip Barker Webb. Berthelot was the son of a Marseille merchant. He joined the French Navy and served as a midshipman during the Napoleonic Wars. After the war he joined the merchant fleet, travelling between Marseilles and the West Indies. He first visited the Canary Islands in 1820, where he taught at a school in Tenerife and managed the botanical gardens at Orotava for the Marquis of Villanueva del Prato. Berthelot studied the natural history of the islands. He was joined in this task by Webb in 1828, and by 1830 they had collected sufficient information for publication. They travelled to Geneva, and produced the first volume of ''L'Histoire Naturelle des Îles Canaries'' in 1835. Berthelot concentrated on the ethnography, history and geography of t ...

John Patrick Micklethwait Brenan
John Patrick Micklethwait Brenan (1917-1985) was a British botanist who became director of the Royal Botanic Gardens, Kew. Brenan was born on 19 June 1917 in Chislehurst and died on 26 September 1985 at Kew. A funeral requiem was held on 3 October 1985 at St. Anne's Church, Kew with a memorial service on the 23rd; he is buried at St. Anne's. Brenan received his Master of Arts in Biology from the University of Oxford in 1940 and began to work at the Imperial Forestry Institute (now the Oxford Forestry Institute) in Oxford. He collected plants from 1947 to 1948 in what is today Zambia and Tanzania. He began work at the herbarium of the Royal Botanic Gardens, Kew in 1948 and became head of its African section in 1959. He became a member of the Linnean Society of London in 1952. In 1965, he became head of the herbarium and assistant director and became director of the Royal Botanic Gardens, Kew in 1976. He was a member of several learned societies, and was president of the Asso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shrub
A shrub (often also called a bush) is a small-to-medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen. They are distinguished from trees by their multiple stems and shorter height, less than tall. Small shrubs, less than 2 m (6.6 ft) tall are sometimes termed as subshrubs. Many botanical groups have species that are shrubs, and others that are trees and herbaceous plants instead. Some definitions state that a shrub is less than and a tree is over 6 m. Others use as the cut-off point for classification. Many species of tree may not reach this mature height because of hostile less than ideal growing conditions, and resemble a shrub-sized plant. However, such species have the potential to grow taller under the ideal growing conditions for that plant. In terms of longevity, most shrubs fit in a class between perennials and trees; some may only last about five y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Asteraceae
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more technicall ...

Endemic
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perennial Plant
A perennial plant or simply perennial is a plant that lives more than two years. The term ('' per-'' + '' -ennial'', "through the years") is often used to differentiate a plant from shorter-lived annuals and biennials. The term is also widely used to distinguish plants with little or no woody growth (secondary growth in girth) from trees and shrubs, which are also technically perennials. Perennialsespecially small flowering plantsthat grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as herbaceous perennials. However, depending on the rigours of local climate (temperature, moisture, organic content in the soil, microorganisms), a plant that is a perennial in its native habitat, or in a milder garden, may be treated by a gardener as an annual and planted out every year, from seed, from cuttings, or from divisions. Tomato vines, for example, live several y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
