Scentless Chamomile/ Scentless False May Weed (Anthemis arvensis, Tripleurospermum perforaturm (Merat) or Matricaria perforata )
      Here's the only thing I've been able to find on this plant so far: From "Natural Toxicants in Feeds, Forages and Poisonous Plants," Peter R. Cheeke, 2nd Edition pg. 449  "...does not seem to be toxic to livestock." It does not appear in A Guide to Plant Poisoning of Animals in North America. I would try feeding it to my animals.
