Tree or Weed leaf identification
Based on the pics provided it appears to be some form of mulberry tree - perhaps a paper mulberry or red mulberry. The paper mulberry has a round fruit , about 3/4 inch diameter that is an aggregate of red drupes. The upper surface is rough and the under surface is velvety. The red mulberry also has a rough upper texture but the lower texture is paler and fuzzy. Its fruit resembles blackberries, cylindrical, about 1 - 1.125 inches long.
Hope this helps.
Thanks so much!
