British NVC Community OV39
British NVC community OV39 (''Asplenium trichomanes'' - ''Asplenium ruta-muraria'' community) is one of the open habitat communities in the British National Vegetation Classification system. It is one of six communities of crevice, scree and spoil vegetation. This community is widely distributed in areas of suitable habitat, especially in the west of Britain. There are two subcommunities. Community composition Four constant species are found in this community: * Wall-rue (''Asplenium ruta-muraria'') * Maidenhair spleenwort (''Asplenium trichomanes'') * Silky wall feather-moss ('' Homalothecium sericeum'') * Wall scalewort (''Porella platyphylla'') Two rare species are associated with the community: * Hutchinsia (''Hornungia petraea'') * Nottingham catchfly (''Silene nutans'') Distribution This community require a lime-rich substrate and its natural habitat is crevices in limestone bedrock, especially in western Britain, where the more humid conditions are favourable to the ...

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'' ...

British Plant Communities
''British Plant Communities'' is a five-volume work, edited by John S. Rodwell and published by Cambridge University Press, which describes the plant communities which comprise the British National Vegetation Classification.

Nort .... The series is a major contribution to plant conservation in Great Britain, and, as such, covers material appropriate for professionals and amateurs interested in the conservation of native plant communities. Each book begins with an introduction to the techniques used to survey the particular vegetations within its scope, discussing sampling, the type of data collected, organizat ...

Asplenium Ruta-muraria
''Asplenium ruta-muraria'' is a species of fern commonly known as wall-rue (but which, as a fern, is not by any means closely related to common rue). It is a very small epipetric species, growing exclusively on limestone and other calcareous rocks. Its fronds are bluish-green and are heavily sub-divided, becoming up to 12 cm in length. Taxonomy Linnaeus first gave wall-rue the binomial ''Asplenium ruta-muraria'' in his '' Species Plantarum'' of 1753. A global phylogeny of ''Asplenium'' published in 2020 divided the genus into eleven clades, which were given informal names pending further taxonomic study. ''A. ruta-muraria'' belongs to the "''Pleurosorus'' subclade" of the "''Pleurosorus'' clade". The ''Pleurosorus'' clade has a worldwide distribution; members are generally small and occur on hillsides, often sheltering among rocks in exposed habitats. ''A. ruta-muraria'' is exceptional within the subclade for its lack of hairs on the leaf. The phylogeny suggests t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asplenium Trichomanes
''Asplenium trichomanes'', the maidenhair spleenwort, is a small fern in the spleenwort genus ''Asplenium''. It is a widespread and common species, occurring almost worldwide in a variety of rocky habitats. It is a variable fern with several subspecies. The binomial nomenclature, specific epithet ''trichomanes'' refers to a Greek word for fern. Description ''Asplenium trichomanes'' grows 10 to 30 cm tall forming tufts arising from a short, scaly rhizome. The scales are dark. The evergreen fronds are long and narrow, gradually tapering towards the tip. They are simply divided into small, yellow-green to dark-green, roundish Frond, pinnae. The stipe (botany), stipe and rachis of the frond are dark all along their length. The fronds can reach 40 cm in length but are more commonly 8–20 cm. The Sorus, indusia are linear to oval, straight, and attached to the upper-side of the fertile vein. There are (2) 4 to 8 sori per pinna and each are 1 to 3.5 mm long. Diplo ...

Silene Nutans
''Silene nutans'' is a flowering plant in the genus ''Silene'', most commonly known as Nottingham catchfly. Description ''Silene nutans'' is a diploid, mainly outcrossing, herbaceous, perennial plant. It grows up to tall, from a branching, woody stock with a thick taproot. The lower leaves are up to long, spathulate and have a long stalk, while leaves higher on the plant are lanceolate, subsessile and acute; all the leaves are covered in soft hairs. The flowers are wide, long, and drooping, on short, viscid stalks. The petals are white or pinkish and divided into two narrow lobes. Each flower remains open for three nights as a means of preventing self-fertilisation; the flower reveals one whorl of stamens on the first night, the second whorl of stamens on the second night, and the three styles on the third night. The seeds are wide and kidney-shaped. Distribution ''Silene nutans'' is widespread across Europe, from southern Spain and Italy north to the British Isles and Sc ...

Fern
A fern (Polypodiopsida or Polypodiophyta ) is a member of a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. The polypodiophytes include all living pteridophytes except the lycopods, and differ from mosses and other bryophytes by being vascular, i.e., having specialized tissues that conduct water and nutrients and in having life cycles in which the branched sporophyte is the dominant phase. Ferns have complex leaves called megaphylls, that are more complex than the microphylls of clubmosses. Most ferns are leptosporangiate ferns. They produce coiled fiddleheads that uncoil and expand into fronds. The group includes about 10,560 known extant species. Ferns are defined here in the broad sense, being all of the Polypodiopsida, comprising both the leptosporangiate (Polypodiidae) and eusporangiate ferns, the latter group including horsetails, whisk ferns, marattioid ferns, and ophioglossoid ferns.
