British NVC community OV6

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
