British NVC community OV6 (Cerastium glomeratum - Fumaria muralis ssp. boraei community) is one of the open habitat communities in the British National Vegetation Classification system. It is one of six arable weed and track-side communities of light, less-fertile acid soils.
It is a widespread community. There are no subcommunities.
Community composition
The following constant species are found in this community: Scarlet pimpernel (Anagallis arvensis) Sticky mouse-ear (Cerastium glomeratum) Common ramping-fumitory (Fumaria muralis ssp. boraei) Toad rush (Juncus bufonius) Annual meadow-grass (Poa annua) Groundsel (Senecio vulgaris) Prickly sow-thistle (Sonchus asper)
Four rare species are associated with the community: Babington's leek (Allium babingtonii) Lesser quaking-grass (Briza minor) Tall ramping-fumitory (Fumaria bastardii) Small-flowered catchfly (Silene gallica)
Distribution
This community is confined to disturbed, fertile, light soils in the damper oceanic climate of south-west England. It is found only in The Scillies and south-west Cornwall. It is closely associated with the Briza minor - Silene gallica community, which often replaces it on drier soils.
Subcommunities
There are three subcommunities: the Aphanes microcarpa - Ranunculus muricatus subcommunity the ''Valerianella locusta - Barbula convoluta subcommunity the Vicia hirsuta - Papaver dubium'' subcommunity
