Euphrasia Vigursii
''Euphrasia vigursii'', also known by its common names of Vigur's eyebright or Cornish eyebright, is an endangered annual of the eyebright family which is endemic to Devon and Cornwall. It is a facultative hemiparasite and needs open conditions and regular grazing of larger shrubs and grasses to grow. It is named after C. C. Vigurs, a Cornish doctor and botanist. Appearance ''E. vigursii'' can be identified by its bright reddish-purple flowers and long glandular hairs on its upper leaves. It has dull grey-green leaves, often permeated with violet or black due to anthocyanins. It is considered a stable hybrid between '' Euphrasia micrantha'' and ''Euphrasia anglica''. Distribution ''E. vigursii'' is endemic to the ''Agrostis curtisii''-'' Ulex galli'' heathlands of South West England, specifically Cornwall and Devon. The largest global population of ''E. virgusii'' is believed to be Lydford High Down in Dartmoor National Park, Devon Devon ( , historically known as Devons ...

Frederick Hamilton Davey
Frederick Hamilton Davey (1868–1915) was a British amateur botanist who devoted most of his leisure time to the study of the flora of Cornwall, England. Born at Ponsanooth in the Kennall Vale, Cornwall to a large family of limited means, he left school aged 11 to work in the Kennall Powder Mills. Encouraged by his father and local vicar, Davey took to Nature Study as his principal recreation. Of rather a weak constitution, he suffered successive bouts of ill-health, but used his convalescence to further his studies. In 1891, aged 23, he submitted his first paper to the Cornwall Polytechnic Society, followed by several more, earning him various medals in recognition of his industry. In 1899, Davey met ornithologist and plant collector A. O. Hume, C.B., founder of the South London Botanical Institute, who was to accompany him on tours of Devon and Cornwall. This was clearly a seminal event, which led to Davey beginning his major opus, ''Flora of Cornwall'', for which he was to ...

Endemic Flora Of England
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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Euphrasia
''Euphrasia'', or eyebright, is a genus of about 450 species of herbaceous flowering plants in the family Orobanchaceae (formerly included in the Scrophulariaceae), with a cosmopolitan distribution. They are semi-parasitic on grasses and other plants. The common name refers to the plant's use in treating eye infections. Many species are found in alpine or sub-alpine meadows where snow is common. Flowers usually are borne terminally, are zygomorphic, and have a lower petal shaped like a lip. The most common flower colours are purple, blue-white, and violet. Some species have yellow markings on the lower petal to act as a guide to pollinating insects. Alternative names, mainly in herbalism, are ''Augentrostkraut, Euphrasiae herba, Herba Euphrasiae'' and ''Herbe d'Euphraise''. Use in herbalism and medicine The plant was known to classical herbalists, but then was not referred to until mentioned again in 1305. Nicholas Culpeper assigned it to the Zodiac sign Leo, claiming that it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dartmoor National Park
Dartmoor is an upland area in southern Devon, England. The moorland and surrounding land has been protected by National Park status since 1951. Dartmoor National Park covers . The granite which forms the uplands dates from the Carboniferous Period of geological history. The landscape consists of moorland capped with many exposed granite hilltops known as tors, providing habitats for Dartmoor wildlife. The highest point is High Willhays, above sea level. The entire area is rich in antiquities and archaeology. Dartmoor National Park is managed by the Dartmoor National Park Authority, whose 22 members are drawn from Devon County Council, local district councils and Government. Parts of Dartmoor have been used as military firing ranges for over 200 years. The public is granted extensive land access rights on Dartmoor (including restricted access to the firing ranges) and it is a popular tourist destination.

Lydford
Lydford, sometimes spelled Lidford, is a village, once an important town, in Devon, north of Tavistock on the western fringe of Dartmoor in the West Devon district. There is an electoral ward with the same name which includes Princetown. The population of this ward at the 2011 census was 2,047. Description The village has a population of 458. The village stands on the small River Lyd, which traverses a deep narrow chasm, crossed by a bridge of single span; and at a little distance a tributary stream forms a cascade in an exquisite glen. The village is noted for its history and surrounding countryside and is popular with tourists. From its Perpendicular church of St Petrock fine views of the Dartmoor tors are seen. The parish of Lydford is immense, embracing some 50,000 acres (200 km2) of land. Close to the church are slight remains of the castle of Lydford. Running south-west from the village is Lydford Gorge, a 1.5-mile (2.4-km) wooded gorge which has been cut through ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heathland
A heath () is a shrubland habitat found mainly on free-draining infertile, acidic soils and characterised by open, low-growing woody vegetation. Moorland is generally related to high-ground heaths with—especially in Great Britain—a cooler and damper climate. Heaths are widespread worldwide but are fast disappearing and considered a rare habitat in Europe. They form extensive and highly diverse communities across Australia in humid and sub-humid areas where fire regimes with recurring burning are required for the maintenance of the heathlands.Specht, R.L. 'Heathlands' in 'Australian Vegetation' R.H. Groves ed. Cambridge University Press 1988 Even more diverse though less widespread heath communities occur in Southern Africa. Extensive heath communities can also be found in the Texas chaparral, New Caledonia, central Chile, and along the shores of the Mediterranean Sea. In addition to these extensive heath areas, the vegetation type is also found in scattered locations acro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ulex Galli
''Ulex gallii'', the western gorse or dwarf furzeA R Clapham, T G Tutin, E F Warburg, ''Flora of the British Isles'', Cambridge, 1962, p. 332 is an evergreen shrub in the pea family (Fabaceae), native to the Atlantic coasts of western Europe: southern Scotland, England, Wales, Ireland, the Isle of Man, western France and the northern coast of Spain. It favours acidic heathy soils and is frequently found in exposed maritime and montane environments. It is more common in the west of its distribution; in eastern England it is replaced in similar habitats by the closely related Dwarf Furze (''Ulex minor''), with very little overlap in the distribution of the two species. ''Ulex gallii'' is usually tall although it may grow up to . The stems are modified into spines, mostly about long, but with some regularly spaced recurved spines of about . Like other members of the genus ''Ulex'' it has trifoliate leaves as a seedling, but later the leaves are reduced to small scales or spines. ...

Stable Hybrid
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
