British NVC Community OV12
British NVC community OV12 (''Poa annua'' - ''Myosotis arvensis'' community) is one of the open habitat communities in the British National Vegetation Classification system. It is one of eight arable weed and wasteland communities of fertile loams and clays. It is a widespread community, in which two subcommunities are recognised.

Vegetation Of Open Habitats In The British National Vegetation Classification System
This article gives an overview of the plant communities formed by vegetation of open habitats in the British National Vegetation Classification system. Introduction The open habitat communities of the NVC were described in Volume 5 of ''British Plant Communities'', first published in 2000, along with the three groups of maritime communities ( shingle, strandline and sand-dune communities, salt-marsh communities and maritime cliff communities). In total, 42 open habitat communities have been identified. The open habitat communities consist of eight distinct subgroups: * six arable weed and trackside communities of light, less-fertile acid soils ( OV1, OV2, OV3, OV4, OV5 and OV6) * eight arable weed and wasteland communities of fertile loams and clays (OV7 OV7, formerly known as La Onda Vaselina, is a Mexican Latin pop group formed in 1989, but it was not until the early 1990s that Onda Vaselina would begin to make their impact. La Onda Vaselina was formed with the membe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Terminology Used In Connection With The British National Vegetation Classification
__NOTOC__ The British National Vegetation Classification or NVC is a system of classifying natural habitat types in Great Britain according to the vegetation they contain. A large scientific meeting of ecologists, botanists, and other related professionals in the United Kingdom resulted in the publication of a compendium of five books: ''British Plant Communities'', edited by John S. Rodwell, which detail the incidence of plant species in twelve major habitat types in the British natural environment. They are the first systematic and comprehensive account of the vegetation types of the country. They cover all natural, semi-natural and major artificial habitats in Great Britain (not Northern Ireland) and represent fifteen years of research by leading plant ecologists. From the data collated from the books, commercial software products have been developed to help to classify vegetation identified into one of the many habitat types found in Great Britain – these include ''MATCH'' ...

Agrostis Stolonifera
''Agrostis stolonifera'' (creeping bentgrass, creeping bent, fiorin, spreading bent or carpet bentgrass) is a perennial grass species in the family Poaceae. Description ''Agrostis stolonifera'' is stoloniferous and may form mats or tufts. The prostrate stems of this species grow to long with long leaf blades and a panicle reaching up to in height. The ligule is pointed and up to long. This differs from common bent, ''Agrostis capillaris'', which is short and does not come to a point. The leaves are tapering, often with a blue-grey colour. The grass is not tufted and the spikelets are red and tightly closed within the panicle. It flowers in July and August. Distribution It can be found growing in a variety of habitats including woodlands, grasslands and meadows, wetlands, riparian zones, and as a pioneer species on disturbed sites. It is native to Eurasia and North Africa (Algeria, Morocco and Tunisia). It is possible that it may also be native to northern parts of ...

Myosotis Arvensis
''Myosotis arvensis'' or field forget-me-not is a herbaceous annual plant, annual to short lived perennial plant, perennial flowering plant in the family Boraginaceae. Clive Stace describes this plant as having the following characteristics: * Upright, to ; softly hairy, with hairs at more-or-less right-angles to the stem. * Flowers grey-blue, across, saucer shaped in profile; sepal tube with hooked hairs; April–October. * Mature fruit dark brown, shiny. * Mature calyx (botany), calyx on spreading stalks longer than sepal tube; calyx (botany), calyx teeth conceal the ripe fruit. * Basal leaves stalked, in a rosette; upper leaves not stalked. * Generally found on open, well drained ground; common throughout the British Isles.

Poa Annua
''Poa annua'', or annual meadow grass (known in America more commonly as annual bluegrass or simply poa), is a widespread low-growing turfgrass in temperate climates. Notwithstanding the reference to annual plant in its name, perennial bio-types do exist. This grass may have originated as a hybrid between ''Poa supina'' and '' Poa infirma''. Description It has a slightly creeping, fibrous, rootstock. The stem grows from 15–25 cm (6-10 in.) high. It is slightly flattened, due to being folded rather than rolled. The panicle is open and triangular shaped, 5 to 7.5 cm (2 to 3 in.) long. The spikelets are stalked, awnless, 1 to 2 cm (3/8 to 3/4 in.) long when flowering, and loosely arranged on delicate paired or spreading branches. Sometimes they are tinged purple. The vivid green leaves are short and blunt at the tips, shaped like the prow of a small canoe. They are soft and drooping. Long sheaths clasp the stem. The leaves are smooth above and below, with fin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poa Trivialis
''Poa trivialis'' (rough bluegrass; ''UK:'' rough-stalked meadow-grass or rough meadow-grass), is a perennial plant regarded in the US as an ornamental plant. It is part of the Poaceae, grass family. Description It is very common in meadows and pastures throughout United Kingdom, Britain. Its preferred habitat is moist, sheltered places. Its wiktionary:herbage, herbage is plentiful and fairly nutritious, though not as much as ''Poa annua'' or ''Poa pratensis''. It is useful for grazing on heavy and damp soil. It also copes well with the polluted atmosphere of towns and cities. It is in flower from June onwards throughout the summer. It is often considered a weed of golf courses. It is an invasive species in the Great Lakes region and was first sighted in 1843. It has short stolons. The leaves are broad and tapering, and the sheathes are very rough. It has shiny leaves like ''Lolium perenne'' and crested dog's-tail. They have pointed ligules 4–10 mm (3/16 – 3/8 in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polygonum Aviculare
''Polygonum aviculare'' or common knotgrass is a plant related to buckwheat and dock. It is also called prostrate knotweed, birdweed, pigweed and lowgrass. It is an annual found in fields and wasteland, with white flowers from June to October. It is widespread across many countries in temperate regions, apparently native to Eurasia, naturalized in temperate parts of the Southern Hemisphere. Description Common knotgrass is an annual herb with a semi-erect stem that may grow from high. The leaves are hairless and short-stalked. They are longish-elliptical with short stalks and rounded bases; the upper ones are few and are linear and stalkless. The stipules are fused into a stem-enclosing, translucent sheath known as an ochrea that is membranous and silvery. The flowers are regular, green with white or pink margins. Each has five perianth segments, overlapping at the base, five to eight stamens and three fused carpels. The fruit is a dark brown, three-edged nut. The seeds need l ...
