Cumberland Spurge (Euphorbia mercurialina)? ID tentative.
Growing at a woodland edge. Leaves alternate, smooth, with ciliate edges. This plant has a superior ovary, meaning the central "female" inflorescence (called a cyathium) is surrounded by several smaller male flowers.

Edit: Went back for more leaf shots (my camera battery died), and it looked like deer or something had eaten the flowers completely!
