True Service-tree
''Cormus domestica'', commonly known as service tree or sorb tree, is a species of tree native to western, central and southern Europe, northwest Africa (Atlas Mountains), and southwest Asia (east to the Caucasus).Rushforth, K. (1999). ''Trees of Britain and Europe''. Collins .Mitchell, A.'' f. ''(1974). ''A Field Guide to the Trees of Britain and Northern Europe'', p 280. Collins It may be called true service tree, to distinguish it from wild service tree. It is the only species in the monotypic genus ''Cormus.'' It is a deciduous tree growing to (rarely to ) tall with a trunk up to diameter, though it can also be a shrub tall on exposed sites. The bark is brown, smooth on young trees, becoming fissured and flaky on old trees. The winter buds are green, with a sticky resinous coating. The leaves are long, pinnate with 13–21 leaflets long and broad, with a bluntly acute apex, and a serrated margin on the outer half or two thirds of the leaflet. The flowers are diamet ...

Édouard Spach
Édouard Spach (23 November 1801 – 18 May 1879) was a French botanist. The son of a merchant in Strasbourg, in 1824 he went to Paris, where he studied botany with René Desfontaines (1750–1831) and Antoine-Laurent de Jussieu (1748–1836). He then became the secretary of Charles-François Brisseau de Mirbel (1776–1854). When de Mirbel became a professor at the Muséum national d'histoire naturelle (National Museum of Natural History), he followed him and remained at the museum for the remainder of his career. He published many monographs, including ''Histoire naturelle des végétaux. Phanérogames'' ("Natural history of plants: Spermatophytes"; fourteen volumes and an atlas, Roret, Paris, 1834–1848), and with Hippolyte François Jaubert (1798–1874), ''Illustrationes plantarum orientalium'' ("Illustrations of plants of the East"; five volumes, Roret, Paris, 1842–1857). The genus ''Spachea'' was named after him by Adrien-Henri de Jussieu [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant Sexuality
Plant reproductive morphology is the study of the physical form and structure (the Plant morphology, morphology) of those parts of plants directly or indirectly concerned with sexual reproduction. Among all living organisms, flowers, which are the reproductive structures of flowering plant, angiosperms, are the most varied physically and show a correspondingly great diversity in methods of reproduction. Plants that are not flowering plants (green algae, mosses, Marchantiophyta, liverworts, hornworts, ferns and gymnosperms such as conifers) also have complex interplays between morphological adaptation and environmental factors in their sexual reproduction. The breeding system, or how the sperm from one plant fertilizes the ovum of another, depends on the reproductive morphology, and is the single most important determinant of the genetic structure of nonclonal plant populations. Christian Konrad Sprengel (1793) studied the reproduction of flowering plants and for the first time it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Camel
The River Camel ( kw, Dowr Kammel, meaning ''crooked river'') is a river in Cornwall, England. It rises on the edge of Bodmin Moor and with its tributaries its catchment area covers much of North Cornwall. The river flows into the eastern Celtic Sea between Stepper Point and Pentire Point having covered about 30 miles, making it the second longest river wholly in Cornwall. The river is tidal upstream to Egloshayle and is popular for sailing, birdwatching and fishing. The name ''Camel'' comes from the Cornish language for 'the crooked one', a reference to its winding course. Historically the river was divided into three named stretches. Heyl ( kw, Heyl, meaning ''estuary'') was the name for the estuary up to Egloshayle, the River Allen ( kw, Dowr Alen, meaning ''shining river'') was the stretch between Egloshayle and Trecarne, whilst the Camel was reserved for the stretch of river between its source and Trecarne.

Bristol
Bristol () is a city, ceremonial county and unitary authority in England. Situated on the River Avon, it is bordered by the ceremonial counties of Gloucestershire to the north and Somerset to the south. Bristol is the most populous city in South West England. The wider Bristol Built-up Area is the eleventh most populous urban area in the United Kingdom. Iron Age hillforts and Roman villas were built near the confluence of the rivers Frome and Avon. Around the beginning of the 11th century, the settlement was known as (Old English: 'the place at the bridge'). Bristol received a royal charter in 1155 and was historically divided between Gloucestershire and Somerset until 1373 when it became a county corporate. From the 13th to the 18th century, Bristol was among the top three English cities, after London, in tax receipts. A major port, Bristol was a starting place for early voyages of exploration to the New World. On a ship out of Bristol in 1497, John Cabot, a Venetia ...

Shirehampton
Shirehampton is a district of Bristol in England, near Avonmouth, at the northwestern edge of the city. It originated as a separate village, retains a High Street with a parish church and shops, and is still thought of as a village by many of its 6,867 inhabitants. Although on the far northwest corner, and largely separated from the rest of Bristol by a broad swathe of parkland extending from the Blaise Castle estate, with the River Avon forming a barrier for access to Somerset, the community is still a convenient location from which to reach all parts of the city. Travel is also easy from Shirehampton into Gloucestershire, South Wales and Somerset since it lies within reach of the main motorways in the area, including the M5, the M4 Second Severn Crossing, and the M49, and it is served by the A4 Portway and by Shirehampton railway station, which allow access to near the city centre. It is informally known to local people as "Shire". Situation Shirehampton looks across the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Site Of Special Scientific Interest
A Site of Special Scientific Interest (SSSI) in Great Britain or an Area of Special Scientific Interest (ASSI) in the Isle of Man and Northern Ireland is a conservation designation denoting a protected area in the United Kingdom and Isle of Man. SSSI/ASSIs are the basic building block of site-based nature conservation legislation and most other legal nature/geological conservation designations in the United Kingdom are based upon them, including national nature reserves, Ramsar sites, Special Protection Areas, and Special Areas of Conservation. The acronym "SSSI" is often pronounced "triple-S I". Selection and conservation Sites notified for their biological interest are known as Biological SSSIs (or ASSIs), and those notified for geological or physiographic interest are Geological SSSIs (or ASSIs). Sites may be divided into management units, with some areas including units that are noted for both biological and geological interest. Biological Biological SSSI/ASSIs may ...

Horseshoe Bend, Shirehampton
Horseshoe Bend, Shirehampton () is an 11 acre (4.45 hectare) biological Site of Special Scientific Interest in Bristol, England, on the north bank of a lower, tidal stretch of the River Avon, Bristol, River Avon, 1.9 miles (3 kilometres) downstream from the Avon Gorge, and just east of the village of Shirehampton. It was notified as an SSSI in 1999. Description The site consists of a wooded cliff and a narrow salt marsh. The underlying rocks are Old Red Sandstone, Devonian sandstone and Carboniferous limestone, overlaid with Triassic Dolomite (rock), dolomitic Conglomerate (geology), conglomerate. Biological interest Wooded cliff The site's principal interest and the reason for its designation as an SSSI is the presence of a population of the True Service-tree (''Sorbus domestica'') growing on the cliffs. This tree is nationally rare in Britain, and this site hosts the largest known population in England. Other notable species of ''Sorbus'' here are the whitebeams ''Sorb ...

Cliff
In geography and geology, a cliff is an area of rock which has a general angle defined by the vertical, or nearly vertical. Cliffs are formed by the processes of weathering and erosion, with the effect of gravity. Cliffs are common on coasts, in mountainous areas, escarpments and along rivers. Cliffs are usually composed of rock that is resistant to weathering and erosion. The sedimentary rocks that are most likely to form cliffs include sandstone, limestone, chalk, and dolomite. Igneous rocks such as granite and basalt also often form cliffs. An escarpment (or scarp) is a type of cliff formed by the movement of a geologic fault, a landslide, or sometimes by rock slides or falling rocks which change the differential erosion of the rock layers. Most cliffs have some form of scree slope at their base. In arid areas or under high cliffs, they are generally exposed jumbles of fallen rock. In areas of higher moisture, a soil slope may obscure the talus. Many cliffs also fea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wyre Forest
__NOTOC__ Wyre Forest is a large, semi-natural (partially unmanaged) woodland and forest measuring which straddles the borders of Worcestershire and Shropshire, England. Knowles Mill, a former corn mill owned by the National Trust, lies within the forest. Natural history The forest covers an area in local terms of 2,634 hectares (6,509 acres), or on the larger scale and is noted for its variety of wildlife. Although now the Wyre Forest has been much deforested, it still extends from east of the A442 at Shatterford, north of Kidderminster in the east, almost to Cleobury Mortimer in the west and from Upper Arley in the north to Areley Kings, near Stourport in the south. It is one of the largest remaining ancient woodlands in Britain. Forestry England looks after around half of today's forest. Around two-thirds of the forest has been designated as an SSSI (1,753.7 Ha), while a further fifth (549 Ha) is listed as a national nature reserve. The Dowles Brook flows through the ...
