There were patches of this very tiny flower on the pathways at a nature reserve. I don't think the leaves most visible in the picture are it's leaves. There are small geranium type leaves dotted around. I have used a 10p to show how small this flower is and would be very grateful for feedback as to what it is. My hunch is that it is a type of Crane's-Bill, but not sure at all.
