Some of the other flowers I found along the wayside at Paxton Pits yesterday. I think the top left photo is a vetch, possibly a bush or a kidney vetch, The yellow one is bird's foot trefoil but when I was little I used to call it Lady's fingers as the red tips were said to resemble painted fingernails. I'm sure you'll recognise the others.
@judithg I think the centre seedhead could be a salsify. We have them on a nearby field. They're very pretty and come in purple or yellow. I didn't think it was a dandelion either but wasn't sure..
