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.

The following constant species are found in this community:
 Scarlet pimpernel (Anagallis arvensis)

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
