Cormus (plant)
''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 the wild service tree (''Torminalis glaberrima''). 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 ...

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 morphology) of those parts of plants directly or indirectly concerned with sexual reproduction. Among all living organisms, flowers, which are the reproductive structures of 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, 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 was understood that the pollination pr ...

River Camel
The River Camel (, 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 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 (, meaning ''estuary'') was the name for the estuary up to Egloshayle, the River Allen (, 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.

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 reserve (United Kingdom), national nature reserves, Ramsar Convention, Ramsar sites, Special Protection Areas, and Special Area of Conservation, Special Areas of Conservation. The acronym "SSSI" is often pronounced "triple-S I". Selection and conservation Sites notified for their Biology, biological interest are known as Biological SSSIs (or ASSIs), and those notified for geological or Physical geography, physiographic interest are Geological SSSIs (or ASSIs). Sites may be divided into management units, with some a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, downstream from the Avon Gorge, and just east 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 Devonian sandstone and Carboniferous limestone, overlaid with Triassic dolomitic 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 '' Sorbus eminens'' and '' Sorbus anglica'', both of which are also nationally rare in Britain. The nationally scarce Large- ...

Glamorgan
Glamorgan (), or sometimes Glamorganshire ( or ), was Historic counties of Wales, one of the thirteen counties of Wales that existed from 1536 until their abolishment in 1974. It is located in the South Wales, south of Wales. Originally an early medieval petty kingdom of varying boundaries known in Welsh as Kingdom of Morgannwg, Morgannwg (or Glywysing), which was then invaded and taken over by the Anglo-Normans, Normans as the Lordship of Glamorgan. The area that became known as Glamorgan was both a rural, pastoral area, and a conflict point between the Normans, Norman lords and the Welsh princes. It was defined by a large concentration of castles. After falling under English rule in the 16th century, Glamorgan became a more stable county, and exploited its natural resources to become an important part of the Industrial Revolution. Glamorgan was the most populous and industrialised county in Wales, and was once called the "crucible of the Industrial Revolution", as it contain ...

Cliff
In geography and geology, a cliff or rock face is an area of Rock (geology), 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 (rock), 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 ...
