Trifolium campestre

Like black medick except with bigger flowers and none of the black seeds. That’s not really helpful if you don’t know what black medick looks like or if you’ve never seen the two growing together and yet I find that the ID books always seem to compare them with each other…it’s so frustrating. On the other hand I can’t think of anything different to write so I’m doing just the same. Not as commonly found as the other plants that look similar.
