Senecio Cruentus
''Pericallis cruenta'' ( syns. ''Senecio cruentus'' and ''Cineraria cruenta'') is a species of flowering plant in the family Asteraceae, native to La Gomera and Tenerife islands of the Canary Islands. It has a nonwoody growth form and is typically found growing in Tenerife's laurel forests. With ''Pericallis lanata'' it is a parent of the widely cultivated garden plant ''Pericallis × hybrida'', the florist's cineraria. In the past, and continuing today, there has been confusion and debate about the identity and origin of ''Pericallis'' × ''hybrida'', with ''Pericallis cruenta'' being incorrectly called a 'feral' form of the florist's cineraria. In 1895 in a series of letters and articles in '' The Gardeners' Chronicle'' and ''Nature'', William Turner Thiselton-Dyer argued that the garden plant ''Cineraria cruenta'' was derived by simple breeding from the wild plant ''Senecio cruentus'', while William Bateson argued that it was of hybrid origin. The argument was resolved by Ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
The Gardeners' Chronicle
''The Gardeners' Chronicle'' was a British horticulture periodical. It lasted as a title in its own right for nearly 150 years and is still extant as part of the magazine ''Horticulture Week''. History Founded in 1841 by the horticulturists Joseph Paxton, Charles Wentworth Dilke, John Lindley and the printer William Bradbury it originally took the form of a traditional newspaper, with both national and foreign news, but also with vast amounts of material sent in by gardeners and scientists, covering every conceivable aspect of gardening. Its first editor, John Lindley, was one of the founders. Another founder, Paxton, later also became editor. Prominent contributors included Charles Darwin and Joseph Hooker. By 1851, the circulation of ''The Gardeners' Chronicle'' was given as 6500. Compared with that of the far more eminent ''Observer'' at 6230, and ''The Economist'' at 3826, ''The Gardeners' Chronicle'' did astonishingly well. Possibly these figures include the Chronicle's lar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Richard Irwin Lynch
Richard is a male given name. It originates, via Old French, from Old Frankish and is a compound of the words descending from Proto-Germanic ''*rīk-'' 'ruler, leader, king' and ''*hardu-'' 'strong, brave, hardy', and it therefore means 'strong in rule'. Nicknames include "Richie", "Dick", "Dickon", " Dickie", " Rich", " Rick", " Rico", "Ricky", and more. Richard is a common English, German and French male name. It's also used in many more languages, particularly Germanic, such as Norwegian, Danish, Swedish, Icelandic, and Dutch, as well as other languages including Irish, Scottish, Welsh and Finnish. Richard is cognate with variants of the name in other European languages, such as the Swedish "Rickard", the Catalan "Ricard" and the Italian "Riccardo", among others (see comprehensive variant list below).

William Bateson
William Bateson (8 August 1861 – 8 February 1926) was an English biologist who was the first person to use the term genetics to describe the study of heredity, and the chief populariser of the ideas of Gregor Mendel following their rediscovery in 1900 by Hugo de Vries and Carl Correns. His 1894 book ''Materials for the Study of Variation'' was one of the earliest formulations of the new approach to genetics. Early life and education Bateson was born 1861 in Whitby on the Yorkshire coast, the son of William Henry Bateson, Master of St John's College, Cambridge. He was educated at Rugby School and at St John's College, where he graduated BA in 1883 with a first in natural sciences. Taking up embryology, he went to the United States to investigate the development of ''Balanoglossus'', a worm-like hemichordate which led to his interest in vertebrate origins. In 1883–4 he worked in the laboratory of William Keith Brooks, at the Chesapeake Zoölogical Laboratory in Hampton, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Form (botany)
In botanical nomenclature, a ''form'' (''forma'', plural ''formae'') is one of the "secondary" taxonomic ranks, below that of variety, which in turn is below that of species; it is an infraspecific taxon. If more than three ranks are listed in describing a taxon, the "classification" is being specified, but only three parts make up the "name" of the taxon: a genus name, a specific epithet, and an infraspecific epithet. The abbreviation "f." or the full "forma" should be put before the infraspecific epithet to indicate the rank. It is not italicised. For example: * '' Acanthocalycium spiniflorum'' f. ''klimpelianum'' or ** ''Acanthocalycium spiniflorum'' forma ''klimpelianum'' (Weidlich & Werderm.) Donald * ''Crataegus aestivalis'' (Walter) Torr. & A.Gray var. ''cerasoides'' Sarg. f. ''luculenta'' Sarg. is a classification of a plant whose name is: ** ''Crataegus aestivalis'' (Walter) Torr. & A.Gray f. ''luculenta'' Sarg.

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 ...

Pericallis × Hybrida
''Pericallis'' × ''hybrida'', known as cineraria, florist's cineraria or common ragwort is a flowering plant in the family Asteraceae. It originated as a hybrid between ''Pericallis cruenta'' and '' P. lanata'', both natives of the Canary Islands. The hybrid was first developed in the British royal gardens in 1777. It was originally known as ''Cineraria'' × ''hybrida'', but the genus ''Cineraria'' is now restricted to a group of South African species, with the Canary Island species being transferred to the genus ''Pericallis''; some botanists also treat it in a broad view of the large and widespread genus ''Senecio''. Some varieties are sold under the trade name Senetti. Cultivation and uses Florist's cinerarias can be raised freely from seeds. For spring flowering the seeds are sown in mid spring in well-drained pots or pans, in soil of three parts loam to two parts leaf mould, with one-sixth sand; cover the seed thinly with fine soil, and press the surface firm.
