# 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
