Clover sprout similar to vetch bud

I pulled weeds out last Saturday.

And, this is one of the war result. 

I noticed that this shape resembled something.....

It's a vetch flower!

They belong to legume family.

So some parts may resemble each other.

Little purple flowers are blooming on vetches.

Petals look like orchid's.
