Sky I think VA Tech has a weed identification guide on their website. www.vt.edu. If I remember right it leads you through the procedure to identify each weed.
University of Missouri has a great ap to put your phone or pad, called ID Weeds. I use it a lot. The picture looks like a bunch of cockle burs... But hard to tell
Thanks kenny and Fire this is the first time I have seen that ugly weed.. I have been looking but haven't found the name of the weed yet but here is the direct link kenny or whoever wants to see it. http://www.ppws.vt.edu/weedindex.htm
