Take a picture again a little more closer so can see if ridges on the leaves, etc. Also go online to your local area university and see is there is a "ID this plant" forum. I was able to do this for Honolulu when I found a stinky Passion flower. - and believe me - I thought somebody dumped garbage near the flower! I didn't know the words to describe but when I got an answer I learned that the word was 'bracts'
It's better to go local sources than the USDA Plant ID site.
Here's a picture of what bracts look like the hairy sticky gnarly cowl around the fruit of a stinky passion:
I don't know but it reminds me a bit of a minor weed here, Chenopodium album or Fat Hen, but it might be a flower, some things can look quite similar. Where do you live? Someone more local to you might be able to recognize if it's a weed or not.
