Barelees Pond
__NOTOC__ Barelees Pond is the name given to a Site of Special Scientific Interest (SSSI) in north Northumberland, England. The site is a kettle hole, a deep pond formed in the void remaining after a submerged glacial calf block melted. Barelees Pond is illustrative of vegetative habitat evolution as peat sediment gradually fills the pond. Location and natural features Barelees Pond is situated in the north-east of England, immediately south of the Anglo-Scottish border in the county of Northumberland, some south-east of the town of Cornhill-on-Tweed. The pond lies within mildly undulating terrain circa above sea level, and is oval in shape, some north to south and east-west. An island has formed to occupy much of the south and midsections of the pond, fringed at the south by a moat of water, the substantial remains of the pond lying to the north end. The local area has a number of other kettle hole ponds; a second, Campfield Kettle Hole, lies west of Barelees. Vegetation ...

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 ...

Menyanthes Trifoliata
''Menyanthes'' is a monotypic genus of flowering plants in the family Menyanthaceae containing the single species ''Menyanthes trifoliata''. The North American form is often referred to as ''M. trifoliata'' var. ''minor'' Michx. It is known in English by the common names bogbean and buckbean. Description ''Menyanthes trifoliata'' has a horizontal rhizome with alternate, trifoliate leaves. The inflorescence is an erect raceme of white flowers. The species occurs in fens and bogs in Asia, Europe, and North America. In eastern North America, it is considered to be a diagnostic fen species. It sometimes creates big quagmires with its thick roots. Taxonomy The name ''Menyanthes'' comes from the Greek words ''menyein'', meaning "disclosing", and ''anthos'', meaning "flower", in reference to the sequential opening of flowers on the inflorescence. Fossil record One fossil seed of ''Menyanthes trifoliata'' has been extracted from borehole samples of the Middle Miocene fresh wate ...

List Of Rosa Species
There is significant disagreement over the number of true rose species. Some species are so similar that they could easily be considered variations of a single species, while other species show enough variation that they could easily be considered to be different species. Lists of rose species usually show more than 320. The numbers 320 to 350 are the figures accepted by most botanists, but as Bailey has pointed out the extreme lumpers Bentham and Hooker only allowed for thirty species, while the extreme splitter Michel Gandoger allowed 4266 species just in Europe and western Asia. Subgenera and sections There are currently four subgenera in ''Rosa'' although there has been some disputes over the years.', The genus Rosa (Rosoideae, Rosaceae) revisited: molecular analysis of nrITS-1 and atpB-rbcL intergenic spacer (IGS) versus conventional taxonomy, 2005 The four subgenera are: *''Hulthemia'' (formerly ''Simplicifoliae'', meaning "with single leaves") containing one or two sp ...

Crataegus Monogyna
''Crataegus monogyna'', known as common hawthorn, one-seed hawthorn, or single-seeded hawthorn, is a species of flowering plant in the rose family Rosaceae. It is native to Europe, northwestern Africa, and West Asia, but has been introduced in many other parts of the world. Names This species is one of several that have been referred to as ''Crataegus oxyacantha'', a name that has been rejected by the botanical community as too ambiguous. In 1793, Medikus published the name ''C. apiifolia'' for a European hawthorn now included in ''C. monogyna,'' but that name is illegitimate under the rules of botanical nomenclature. Other common names include may, mayblossom, maythorn, (as the plant generally flowers in May in the English-speaking parts of Europe) quickthorn, whitethorn, motherdie, and haw. Description The common hawthorn is a shrub or small tree up to about tall, with a dense crown. The bark is dull brown with vertical orange cracks. The younger stems bear shar ...

Sambucus Nigra
''Sambucus nigra'' is a species complex of flowering plants in the family Adoxaceae native to most of Europe. Common names include elder, elderberry, black elder, European elder, European elderberry, European black elderberry and tramman (Isle of Man). It grows in a variety of conditions including both wet and dry fertile soils, primarily in sunny locations. The plant is widely grown as an ornamental shrub or small tree. Both the flowers and the berries have a long tradition of culinary use, primarily for cordial and wine. Although elderberry is commonly used in dietary supplements and traditional medicine, there is no scientific evidence that it provides any benefit for maintaining health or treating diseases. Description Elderberry is a deciduous shrub or small tree growing to tall and wide, rarely reaching tall. The bark, light gray when young, changes to a coarse gray outer bark with lengthwise furrowing, lenticels prominent. The leaves are arranged in opposite pairs, ...
