Description:

Trifolium campestre is one of the commonest annual trefoils of the Mediterranean region. Thousands of annuals evolved around the Mediterranean where they grow one besides the other. Up to half of the Mediterranean flora (and sometimes more) is annual. This is why many evolution research projects are held in this region. If u look at the corolla, u can see that it doesn't wilt, it curves down and seves later as a wing for the seed wind-disperal.
