Solitary plant found on outskirts of St Davids; not far from coastal path.
No interactions present.
Common Fumitory would have a spoon-shaped lower petal which this does not. I cannot be sure which of the others it is, perhaps muralis.
Many thanks, cicuta58, for your feedback; haven't knowingly come across the Fumaria family before, so ID was based solely on comparison with Rose. Chose officinalis because it was reckoned to be the commonest in the south.
Unfortunately, Rose doesn't mention the "spoon-shaped" lower petal, but some of the flower heads in Picture 1 have a projecting lower lip; presume, from your comment, that they aren't wide enough?
Title changed to Fumitory Variant.
