British NVC community OV15 (Anagallis arvensis - Veronica persica community) is one of the open habitat communities in the British National Vegetation Classification system. It is one of two arable weed communities of light lime-rich soils.
It is a widely-distributed community in south-east England, but is found only locally, its distribution being restricted to areas of suitable soils.
There are four subcommunities.

The following constant species are found in this community:
Two rare species are associated with the community:
A distinctive feature of most occurrences of this community is the presence, in mid- to late-summer, of Kickxia, represented by one or both of K. spuria and K. elatine, and Euphorbia exigua.
This community occurs widely across south-east England, but, being dependent on lime-rich soils, it occurs only locally, typically as a weed community of cereal crops.
It is essentially the same as the Kickxietum spuriae assemblage described by Kruseman and Vlieger.
There are three subcommunities:
