Linaria Arenaria
''Linaria arenaria'', sometimes called sand toadflax or French toadflax, is a yellow-flowered member of the genus ''Linaria''. It is found in sand-dunes and sandy grassland in western France, north-west Spain and Portugal and is thus a psammophyte plant . It is found casually in England and reliably at two sites. One is Braunton Burrows in north Devon where it was planted around 1893 and continues to grow, and the other, since 2004, is in north Somerset. Description It is an annual plant and grows to around . The leaves and stem are covered in sticky hairs. The flowers open in June-July. They are in a cluster at the top of the stem and are yellow with a purplish spur. The species was first described by Augustin Pyramus de Candolle Augustin Pyramus (or Pyrame) de Candolle (, , ; 4 February 17789 September 1841) was a Swiss botanist. René Louiche Desfontaines launched de Candolle's botanical career by recommending him at a herbarium. Within a couple of years de Candol .. ...

Catalogue Of Life
The Catalogue of Life is an online database that provides an index of known species of animals, plants, fungi, and microorganisms. It was created in 2001 as a partnership between the global Species 2000 and the American Integrated Taxonomic Information System. The Catalogue is used by research scientists, citizen scientists, educators, and policy makers. The Catalogue is also used by the Biodiversity Heritage Library, the Barcode of Life Data System, Encyclopedia of Life, and the Global Biodiversity Information Facility. The Catalogue currently compiles data fro165 peer-reviewed taxonomic databasesthat are maintained by specialist institutions around the world. , the COL Checklist lists 2,067,951 of the world's 2.2m extant species known to taxonomists on the planet at present time. Structure The Catalogue of Life employs a simple data structure to provide information on synonymy, grouping within a taxonomic hierarchy, common names, distribution and ecological environment.

Linaria
''Linaria'' is a genus of almost 200 species of flowering plants, one of several related groups commonly called toadflax. They are annuals and herbaceous perennials, and the largest genus in the Antirrhineae tribe of the plantain family Plantaginaceae. Taxonomy ''Linaria'' was traditionally placed in the family Scrophulariaceae. Phylogenetic analysis has now placed it in the vastly expanded family Plantaginaceae. Closely related genera include '' Nuttallanthus'' (American toadflaxes, recently split from ''Linaria''), ''Antirrhinum'' (snapdragons) and ''Cymbalaria'' (ivy-leaved toadflaxes). Cultivation Several ''Linaria'' species are cultivated as garden plants, and some are regarded as having a weedy habit. *Common toadflax or butter-and-eggs (''Linaria vulgaris''), a European species which is widely introduced elsewhere and grows as a common weed in some areas. *Broomleaf toadflax or Dalmatian toadflax ('' Linaria genistifolia'', syn. ''L. dalmatica''), a native of southe ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Psammophyte
A psammophyte is a plant that grows in sandy and often unstable soils. Psammophytes are commonly found growing on beaches, deserts, and sand dunes. Because they thrive in these challenging or inhospitable habitats, psammophytes are considered extremophiles, and are further classified as a type of psammophile. Etymology The word "psammophyte" consists of two Greek roots, ''psamm-'', meaning "sand", and ''-phyte'', meaning "plant". The term "psammophyte" first entered English in the early twentieth century via German botanical terminology. Description Psammophytes are found in many different plant families, so may not share specific morphological or phytochemical traits. They also come in a variety of plant life-forms, including ephemeral plant, annual ephemerals, perennials, subshrubs, Raunkiær plant life-form#Hemicryptophytes, hemicryptophytes, and many others. What the many diverse psammophytes have in common is a resilience to harsh or rapidly fluctuating environmental facto ...

Braunton Burrows
Braunton Burrows is a sand dune system on the North Devon coast. It is privately owned and forms part of the Christie Devon Estates Trust (see Tapeley Park). Braunton Burrows is a prime British sand dune site, the largest sand dune system (psammosere) in England. It is particularly important ecologically because it includes the complete successional range of dune plant communities, with over 470 vascular plant species. The short turf communities are very rich in lichens and herbs, and the dune slacks are also rich. The many rare plants and animals include 14 with UK Biodiversity Action Plans. For example, this is one of only two sites in the UK for the Amber Sandbowl Snail '' Catinella arenaria'', which is found on the wet dune slacks. History The Devon historian Tristram Risdon (d.1640) wrote as follows: " Santon is in the parish of Branton, not unaptly so termed the ''town by the sand not'', that hath overblown many hundred acres of land. And near this hamlet the country p ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Augustin Pyramus De Candolle
Augustin Pyramus (or Pyrame) de Candolle (, , ; 4 February 17789 September 1841) was a Swiss botanist. René Louiche Desfontaines launched de Candolle's botanical career by recommending him at a herbarium. Within a couple of years de Candolle had established a new genus, and he went on to document hundreds of plant families and create a new natural plant classification system. Although de Candolle's main focus was botany, he also contributed to related fields such as phytogeography, agronomy, paleontology, medical botany, and economic botany. De Candolle originated the idea of "Nature's war", which influenced Charles Darwin and the principle of natural selection. de Candolle recognized that multiple species may develop similar characteristics that did not appear in a common evolutionary ancestor; a phenomenon now known as convergent evolution. During his work with plants, de Candolle noticed that plant leaf movements follow a near-24-hour cycle in constant light, suggestin ...

Flora Of France
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms ''gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de Phy ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Flora Of Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be separated from Asia by the watershed of the Ural Mountains, the Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits. "Europe" (pp. 68–69); "Asia" (pp. 90–91): "A commonly accepted division between Asia and Europe ... is formed by the Ural Mountains, Ural River, Caspian Sea, Caucasus Mountains, and the Black Sea ...
