Identification difficulty
ID guidance

There is a very common and similar white daisy of waste ground and arable margins - Scented Mayweed (Matricaria recutita (synonym = M. chamomilla).  Both species can be aromatic.  The best way to tell is to slice through the boss of yellow florets (the receptacle) in the centre of the flower with your thumbnail; Scented Mayweed has a definitely hollow receptacle and Scentless Mayweed has a more or less solid receptacle. 

Chamomile (Chamaemelum nobile), Corn Chamomile (Anthemis arvensis), Stinking Chamomile (Anthemis cotula) and Austrian Chamomile (Cota austriaca (synonym = Anthemis)) have all been recorded in VC55, but are scarce or very rare; a specimen will be needed to verify them.  They all have scales among the yellow florets on the receptacle, unlike Matricaria or Tripleurospermum.  Corn or Austrian Chamomile are often included in seed-mixes of cornfield annuals, and are occasionally naturalised.
