British NVC community OV17

British NVC community OV17 (Reseda lutea - Polygonum aviculare community) is one of the open habitat communities in the British National Vegetation Classification system. Although classed with communities OV15 and OV16 as an arable weed community of light lime-rich soils, it also shares many features with the communities classed as arable weed and wasteland communities of fertile loams and clays.

This community is not found elsewhere in Europe, and in Britain is found only in East Anglia. It was first described by Silverside (1977), who labelled it the Descurainio-Anchusetum arvensis association.

There are no subcommunities.
