As Promised...My Amazing Find

I told you I had a surprise. I think it is pretty special but I am aware this may be something rather normal that I am simply unaware of. There are several opinions floating around here.

I found this on my walk yesterday. It was from a stalk that had no other leaves like it. The rest were green with no markings. If I'd had my camera I would have taken a photo to show you. I brought this home as I was convinced it was a sign for something.
What do you think it means? Do you know how it happened? Tell me what you know.
But mostly, don't you agree? Isn't it wonderful?
