This weed is taking over our yard. We have searched the web and cannot find a match to identify it. There is a teeny tiny white flower with a yellow center that grows on it -- so tiny it is almost invisible to the eye and too small to capture a picture of it. Please click the link below for a picture. Please help identify this weed, and if possible, how to kill it. Thanks in advance for your help!
