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'' ...

Crepis Capillaris
''Crepis capillaris'', the smooth hawksbeard, is a species of flowering plant in the tribe Cichorieae within the family Asteraceae, and is native to Europe. It has become naturalized in other lands and is regarded as a weed in some places. ''Crepis capillaris'' is a low, annual plant common in disturbed ground and open habitats, such as thin grassland, lawns, spoil heaps, rocky banks and on roadsides, the stems often trailing along the ground but sometimes erect, the leaves sometimes forming a rosette. It flowers from June to December in the Northern Hemisphere, producing an array of numerous small flower heads. Each head has as many as 60 yellow ray florets but no disc floret The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae w ...s. References External links *Jepson Manual Treatme ...

Digitaria Ischaemum
''Digitaria ischaemum'' is a species of crabgrass known by the common names smooth crabgrass and small crabgrass. It is native to Europe and Asia, but it is known throughout much of the warm temperate world as an introduced species and often a common roadside and garden weed. It is an annual grass producing an inflorescence with two or more narrow branches lined with tiny spikelets. It is easily confused with other members in the genus, particularly southern crabgrass in California which differs by having spikelets of nearly twice the length. It may also be confused with Bermuda Grass, but differs in being a much taller plant with a much longer inflorescence. The leaves on this grass often form above the base of the plant, and it is usually singular, rarely forming large clumps.

Elytrigia Repens
''Elymus repens'', commonly known as couch grass, is a very common perennial species of grass native to most of Europe, Asia, the Arctic biome, and northwest Africa.

Other names include common couch, twitch, quick grass, quitch grass (also just quitch), dog grass, quackgrass, scutch grass, and witchgrass.Flora of NW Europe''Elytrigia repens''/ref>Flora of China''Elytrigia repens''/ref> Description It has creeping rhizomes which enable it to grow rapidly across grassland. It has flat, hairy leaves with upright flower spikes. The stems ( 'culms') grow to 40–150 cm tall; the leaves are linear, 15–40 cm long and 3–10 mm broad at the base of the plant, with leaves higher on the stems 2–8.5 mm broad. The flower spike is 10–30 cm long, with spikelets 1–2 cm long, 5–7 mm broad and 3 mm thick with three to eight floret ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erodium Cicutarium
''Erodium cicutarium'', also known as common stork's-bill, redstem filaree, redstem stork's bill or pinweed, is a herbaceous annual plant, annual – or in warm climates, biennial plant, biennial – member of the family Geraniaceae of flowering plants. It is native to Macaronesia, temperate Eurasia and north and northeast Africa, and was introduced to North America in the eighteenth century, where it has since become naturalized, particularly of the deserts and arid grasslands of the southwestern United States. Description It is a hairy, sticky annual, resembling Geranium robertianum, herb Robert but lacking the unpleasant odor. The stems are reddish and bear bright pink flowers, which often have dark spots on the bases. The flowers are arranged in a loose cluster and have ten filaments – five of which are fertile – and five styles. The leaves are pinnate to pinnate-pinnatifid, with hairy stems. The long seed-pod, shaped like the bill of a stork, bursts open in a spiral whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
Senecio Vulgaris
''Senecio vulgaris'', often known by the common names groundsel and old-man-in-the-spring, is a flowering plant in the family Asteraceae. It is an annual herb, native to Europe and widely naturalised as a ruderal species in suitable disturbed habitats worldwide. Description ''Senecio vulgaris'' is an erect herbaceous annual growing up to 16 inches (45 cm) tall. The inflorescences usually lack ray florets, the yellow disc florets mostly hidden by the bracts giving the flowers an inconspicuous appearance. ''Senecio vulgaris'' is very similar to ''Senecio viscosus'' but ''S. vulgaris'' does not have the glandular hairs and ray florets found in ''S. viscosus''. Leaves and stems Upper leaves of ''Senecio vulgaris'' are sessile, lacking their own stem ( petiole), alternating in direction along the length of the plant, two rounded lobes at the base of the stem ( auriculate) and sub-clasping above. Leaves are pinnately lobed and + long and wide, smaller towards the top of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
